    TECHNICAL FIELD
    [001] Modalities of the invention refer to drip irrigation emitters and methods of retaining emitters parts together. BACKGROUND
    [002] Drip irrigation emitters can be formed from several parts, such as an external housing formed, for example, from two members. Drip emitters typically include an inlet through which liquid seeping into a tube can enter the emitter and an outlet through which liquid which has entered the emitter can escape to the outside environment. In addition, drip emitters typically include cavities for liquid, such as an outlet bowl on one side of the emitter that is fitted to the tube, a flow path formed at least in part of a flow restriction path, and a flow regulating chamber. pressure.
    [003] The flow restriction path works to control the flow with which the liquid is discharged by the emitter and is usually referred to as a "labyrinth channel" or "labyrinth". Through the flow restriction path, liquid entering the emitter must drain to reach the outlet of the emitter where it empties via the outlet basin to the outside. The flow restriction path is a high-resistance flow channel along which pressure of liquid seeping through the emitter drops relatively quickly with the distance along the path. Therefore, in some cases it may be advantageous to form the longest flow restriction path.
    [004] A resiliently flexible component often referred to as a membrane or diaphragm can be used in an emitter as part of the pressure regulating chamber to control the flow of liquid flowing out of the emitter, so that it is substantially independent of the pressure of input to a pressure range typically found in irrigation applications that can equal a flow between about 0.4 and 12 liters per hour (1 / h). The membrane is usually located between the entrance and the exit and can contain on one side liquid that enters the entrance of the emitter to pass through the labyrinth and on the other side that has already passed through the labyrinth and reached a pressure regulating chamber that in some cases is located adjacent to the emitter outlet.
    [005] The pressure regulating chamber typically has a wider cross section than the maze that empties into it, in order to establish an improved pressure regulating performance for the emitter. The membrane in response to the pressure increase of the incoming liquid, can flex in the pressure regulating chamber to restrict the flow of liquid that leaves the outlet and through which to act to control the flow of liquid that flows out of the emitter.
    [006] Various types of connections can be used in order to bring together parts of a drip irrigation emitter and in particular parts constituting external housing members of the emitter. In addition, several considerations can be taken regarding the arrangement of the emitter's liquid cavities in relation to each other in order to obtain an optimum design for the intended use and performance of the emitter.
    [007] US patent 6,206,305 describes an emitter unit adapted to be integrally connected to an inner surface of a tube. The emitter has an external housing, an entrance that communicates with an interior of the tube; an outlet communicating with a tube outlet and a flow restriction path. The housing has a closed box format and includes a receiving member and a corresponding cover member. Projection means and interlocking recesses formed on these members are adapted to form a tight pressure fitting to ensure effective retention between these members after assembly and before being connected to a tube. The emitter also includes a pressure regulating chamber and a flow restriction path located inside the housing and an outlet bowl on the outside of the housing where the emitter connects to the tube
    [008] PCT publication WO2012 / 137200 describes a drip emitter integrally installed inside a tube. The emitter has a body that on its side which is affixed to the inner wall of the tube is formed with an outlet bowl that is elongated in its dimensions and extends substantially along the entire length of the body. The emitter also has on this side that a flow passage is attached to the tube that circumferentially surrounds the elongated outlet basin in order to give the emitter a symmetrical configuration on the side that connects to the tube and by which the need for dripper orientation before being fitted into a tube. SUMMARY
    [009] The following modalities and aspects of it are described and illustrated in conjunction with systems, tools and methods that are understood to be exemplary and illustrative and not limiting the scope.
    [0010] In accordance with an embodiment of the present invention, a drip irrigation emitter is provided extending between a first and a second longitudinal ends, the emitter comprising an external side for attachment to a pipe which is laterally limited between a first and a second longitudinal edges.
    [0011] The outer side can be connected to the tube by heat and the display can preferably be on the inner side of a wall of the tube. The first and second longitudinal edges that limit the outer side of the emitter possibly also define lateral ends where the outer side is still attached to the tube where in addition to these ends the emitter is not attached to the tube and generally leans out from the inner side the tube wall.
    [0012] The outer side comprises a flow path and an outlet basin, in which at least one section of the flow path extends downstream along the first edge and at least a portion of the outlet basin is formed between the section of the flow path and the second edge, that is, extending to adjacent the second edge with no other formation, for example, of liquid between them.
    [0013] The outlet basin can be defined as having a maximum longitudinal extension possibly extending along the entire (or a large portion) of the section of the flow path that extends along the first edge. The outlet basin can furthermore be defined as having a maximum lateral extension, for example, in at least a portion of the basin that is formed between the section of the flow path and the second edge.
    [0014] The maximum longitudinal extent, possibly at least 5 mm in length, is configured to establish a length sufficient to allow a medium such as a drill to penetrate the tube to penetrate the tube at a location above the outlet basin. The maximum lateral extension is adapted, for example, to compensate for lateral distortions formed during the formation of a drip tube, such as by twisting the tube, in order to similarly establish a sufficient extension, lateral here, for the medium that penetrates the tube - to penetrate the tube at a location above the outlet basin.
    [0015] Possibly, the section of the flow path constitutes a full length of the flow path, while in other cases the section constitutes a first section that can be followed by one or more sections of the flow path that possibly partially surround a portion the outlet basin possibly including an emitter outlet.
    [0016] In a form of the invention, a modality is provided where the emitter comprises a first member comprising the outer side and also comprises a lower inner side comprising a cavity. The cavity in the emitter can form a pressure regulating chamber of the emitter when, for example, covered by a membrane and this chamber can be used to control the flow of liquid flowing out of the emitter, so that it is substantially independent of the inlet pressure. for a pressure range typically found in irrigation applications.
    [0017] In a preferred embodiment, the flow path extends downstream to a terminal end where it communicates with the cavity and preferably a full length of the flow path is a pressure reduction path, possibly including a group of these opposing baffles between which the liquid is restricted from flowing.
    [0018] Communication with the cavity can be via a passage through which the flow path communicates downstream with the cavity or chamber and from which additional communication downstream is via a passage forming an emitter outlet through which liquid it can flow downstream to the outlet basin and from there to the outside environment.
    [0019] According to one aspect of the present invention there is thus provided a drip emitter with an optimized arrangement of cavities for liquid. Such optimization can be established on the one hand by an asymmetric arrangement of cavities on the external side affixing to the tube which allows a long extension of the flow path along a lateral edge on this side (possibly along substantially all of this lateral edge ) while leaving a relatively large space for an outlet basin to be formed along all or most of the longitudinal extent on this side and between the flow path and the other side edge (or at least part of the other edge side) on this side. On the other hand, locating the flow path on the outer side leaves room for a relatively large cavity or pressure regulating chamber to be formed at another location on the emitter, preferably on a side opposite the outer side.
    [0020] In accordance with an aspect of the present invention, a method is also provided for forming a drip irrigation tube equipped with emitter modalities according to the present invention including such sides as symmetrically external. The method involves providing a tube formed around a geometric axis of the tube and providing a plurality of drip emitters, each emitter extending between a first and a second longitudinal end and comprising an external side extending along an axis longitudinal geometric and being laterally limited between a first and a second longitudinal edges equally spaced from the longitudinal geometric axis.
    [0021] The method further comprises a step of orienting each emitter in such a way that its longitudinal geometric axis is generally parallel to the geometric axis of the tube and then fitting each emitter on a wall of the tube, and at the same time that it then forms opening through the wall above the external side of each transmitter in a location laterally away from the longitudinal geometric axis of the emitters.
    [0022] According to one aspect of the present invention, a drip irrigation emitter comprising a first and a second member extending longitudinally is also provided, only the first member being adapted to attach from the outside to a pipe and the second member being adapted to fit snugly to the first member, where the second member comprises a base and a peripheral wall that rises above the base to enclose a recess, the first member comprises an inner side and a peripheral surface which extends a distance in height from the inside to the outside, and the first member is at least partially located in the recess with the walls surrounding the peripheral surfaces over at least part of the height.
    [0023] Possibly, the wall comprises along at least part of its periphery a plurality of teeth projecting into the recess, the peripheral surface comprising along at least part of its periphery a frieze, and at least some teeth are adapted to engage the frieze from above.
    [0024] Preferably, the teeth support against the frieze from above to press the first member towards the second member.
    [0025] Typically, the emitter comprises valleys formed on both sides of each tooth.
    [0026] If desired, the first and second members are formed from different materials, with preferably the material of the second member being harder and / or more resistant than the material of the first member.
    [0027] In addition to the exemplary aspects and modalities described above, other aspects and modalities will become evident by reference to the figures and by studying the following detailed descriptions. BRIEF DESCRIPTION OF THE FIGURES
    [0028] Exemplary modalities are illustrated in the referenced figures. It is intended that the modalities and figures described here should be considered illustrative, rather than restrictive. The invention, however, as to the organization and method of operation, together with its objectives, characteristics and advantages, can be better understood by reference to the following detailed description when taken with the attached figures, in which: Fig. 1 shows schematically a top perspective view of an emitter embodiment according to the present invention including a first and a second member; Fig. 2 schematically shows an exploded view of Fig. 1 revealing an emitter membrane; Fig. 3 schematically shows a separate view of the first and second members; Fig. 4 schematically shows a side view of the emitter side of Fig. 1, partly in cross section; Figs. 5A and 5B schematically show, respectively, another perspective view and a longitudinal side view of the emitter of Fig. 1; Figs. 6A and 6B schematically show, respectively, a top perspective view and a separate view of first and second members forming another embodiment of an emitter according to the present invention; Figs. 7A and 7B schematically show, respectively, a top perspective view and a separate view of first and second members forming yet another embodiment of an emitter according to the present invention.
    [0029] It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures were not drawn to scale. For example, the dimensions of some of the elements can be exaggerated in relation to other elements for clarity. In addition, where deemed appropriate, reference numbers can be repeated within the figures to indicate identical elements. DETAILED DESCRIPTION
    [0030] Attention is first directed to Fig. 1 showing a drip irrigation emitter 10 according to an embodiment of the present invention that possibly includes a first member 12 and a second member 14. The first member has an external side 16 here fully visible that is formed with a flow path 18 next to an outlet bowl 20 of the emitter. The flow path 18 here is optionally formed along its total length as a flow restriction path, possibly including groups of opposing deflector teeth 21 to create high resistance to liquid flow. Each of the first and second members possibly has an elongated shape and the emitter 10 is adapted to fix preferably by heat connection to an inner side of a tube 23 on the outer side 16 (tube seen, for example, in Fig. 4 ).
    [0031] It should be noted that directional terms appearing throughout the specification and claims, for example, "front", "rear", "up", "down" etc., (and derivatives thereof) are for illustrative purposes only, and are not intended to limit the scope of the appended claims. In addition, it is noted that the directional terms "down", "below" and "bottom" (and derivatives thereof) define identical directions.
    [0032] The outer side 16 is laterally bounded between two edges extending longitudinally edges 22, 24 and outlet bowl 20 is laterally bounded between two longitudinal flanks and facing away from each other 17, 19. The flow path 18 extends longitudinally in this modality along only one of the edges 22 from a beginning 26 to an end 28 and outlet basin 20 extends longitudinally between the flow path 18 and the other edge 24, with a first among the flanks 17 of the basin outlet 20 being adjacent to flow path 18 and a second between flanks 19 of outlet basin 20 adjacent to edge 24. The first member 12 thus in the mode shown includes on its outer side 16, side by side, only a single path of flow 18 and a single outlet basin 20, such that a lateral geometric axis L, perpendicular to the longitudinal geometric axis G, extending from edge 22 to edge 24 crosses: first the flow path 18, immediately and thereafter the outlet basin 20, at the same time immediately thereafter reaching the edge 24.
    [0033] Attention is now directed to the exploded view of the emitter 10 seen in Fig. 2 which schematically illustrates the first and second emitter members 10 and a membrane 30 which in an assembled state of the emitter 10 is interposed between the members. The first member 12 includes an outlet 32 of the emitter seen here emptying into the outlet bowl 20. The second member 14 is formed with an inlet embodied here as a filter including a plurality of slots 36. The second member 14 includes a base 38 and a peripheral wall 40 that rises above the base to wax a recess 42, and the slits 36 of the entrance are formed along the base 38 extending through the base 38 opening on its inner side into the recess 42 and on its other side to an external side of member 14 (not visible in this view) which is adapted to face a tube in which the emitter 10 is installed.
    [0034] Wall 40 is formed along a periphery on its side facing recess 42 with a plurality of teeth 44 projecting g into recess 42; and valleys 46 are formed on both sides of each tooth 44 in the peripheral direction. The first member 12 has an inner side 48 (not entirely seen here) and a peripheral surface 50 that extends a distance in height from the inner side to the outer side 16. The peripheral surface 50 meets the outer side 16 in a peripheral edge of generally rectangular shape 52 that includes the two longitudinal edges 22, 24 and the two lateral edges 25, 27. The peripheral surface 50 includes, along each of its longitudinal sides, a rib extending longitudinally 54 and along each of its lateral sides, a frieze extending laterally 56, with all friezes 54, 56 being located possibly as seen here adjacent to the inner side 48.
    [0035] With attention directed back to Fig. 1 it is appreciated that in the formation of an assembled state of emitter 10, the first and the second members 12, 14 are retained together first requesting the first member 12 inside the recess 42. Do thus it takes the wall 40 of the second member 14 to enclose the peripheral surface 50 of the first member 12 and the teeth 44 of the second member 14 to fit just over the ribs 54, 56 of the first member 12.
    [0036] This forms an interlocking relationship where the teeth 44 rest against the ribs from above and by which they and hold the first member 12 pressed against the second member 14. It is noted that the provision of the valleys 46 on both sides of each tooth 44 increases the flexibility of the teeth so that they can flex more easily when fitting over the friezes and thus reduce the likelihood of deformations in interlocking parts of the emitter that can occur (or be larger) if, for example, the valleys are absent.
    [0037] Attention is now directed to Fig. 3. The first member 12 is formed adjacent to one of the longitudinal ends of its inner side 48 with a chamber 58 here in the form of a cylindrical cavity. The second member 14 is formed similarly adjacent to one of the longitudinal ends of the inner base 38 facing the recess 42 with a chamber 60 here also in the form of a cylindrical cavity. Each chamber 58, 60 is preferably dimensioned to have a lateral extension, here a diameter, which extends over an almost total lateral width of sides on which they are formed. The base 38 is formed with a central rail extending longitudinally 62 with the slits 36 being formed on the lateral sides of the rail, and along the rail 36 in a center of the chamber 60 a bulging projected 64 is formed.
    [0038] The inner side 48 of member 12 has a plurality of ducts extending laterally 66 seen here mainly straight with an adjacent chamber 58 being curved. The ducts all open into a longitudinally extending channel 68 generally located below the flow path 18 on the other outer side 16 of the member 12 where it extends along edge 22. Channel 68 at one end distal to chamber 58 it communicates via a hole 70 formed through the first member 12 with the beginning 26 of the flow path 18, and the outlet 32 opens into a center of the chamber 58 which in turn communicates via a hole 72 formed through of member 12 with end 28 of flow path 18.
    [0039] Attention is directed to Fig. 4 showing a partial cross-sectional view of a mounted state of the emitter 10. In the emitter 10, the membrane 30 is located between chambers 58 and 60 and is pressed from below its center by the bulge 64 to ensure that it is raised above the slits 36 opening into the chamber 60. A membrane periphery 30 is bounded from above by a part of the first member 12 while being free from below to ensure that it performs the appropriate curving during the operation of the emitter. The chamber 58 which is sealed from below by the membrane 30 forms a pressure regulating chamber of the emitter. Preferably, the chamber 58 is formed, inter alia, laterally as wide as possible on the side 48 to improve the pressure regulating properties of the emitter 10.
    [0040] At the emitter 10 the slits 36 outside the chamber 60 are located in line with corresponding ducts 66 of the first member 12 so that at least most of the slits 36 each communicate with an associated duct 66 from above. Also seen in this view is that the emitter is attached to an internal face of the tube 23 in which it is fitted by which the outlet bowl 20 communicates with the outside environment via an opening 76, here embodied with the orifice, which is formed through the tube wall.
    [0041] During irrigation, pressurized liquid in the tube 23 enters the emitter 10 via the slits 36 formed in the second member 14 and from where the liquid flows via the ducts 66 formed in the first member 12 into the channel 68. From from channel 68 liquid flows upwards via hole 70 to the beginning 26 of flow path 18. The liquid flowing downstream via flow path 18 reaches the end 28 from where liquid flows back down via hole 72 into the pressure regulator chamber 58 of the emitter.
    [0042] In chamber 58 the flow of liquid flowing forward downstream from the emitter via outlet 32 is regulated to be substantially independent of the inlet pressure for a pressure range in which the emitter was designed to operate. The mechanism for regulating the liquid flow that leaves the emitter 10 includes the curving of the membrane 30 in response to liquid pressure acting on its side facing the slits 36, so that a rise or fall in pressure in the pipe, respectively, decreases or increase the path available for liquid to leave chamber 58 via outlet 32 to basin 20 and from there to the outside environment.
    [0043] With attention directed to Fig. 5A and 5B it can be seen that the emitter 10 can be formed with a step extending longitudinally 78 formed by removed material or lacking on the outside of second member 14. Due to step 78 , the emitter 10 is asymmetrical in a view taken along the longitudinal geometric axis G. This asymmetric shape of the emitter 10 can assist in correctly orienting the emitter when or before it is fitted to the inner side of the tube wall 23.
    [0044] In Figs. 5A and 5B the geometric axis G can also represent, in the embodiment shown here, a central geometric axis C that defines a center, for example, the outer side 16 which is equally spaced from the edges 22, 24. The outlet bowl 20 as seen, for example, in Fig. 5 A is thus symmetrically located on the outer side 16 since, for example, the central geometric axis C is not equally spaced from the flanks 17, 19. In another possible way, the outlet basin 20 can be defined asymmetrically formed around a plane (not shown), possibly also being a median plane of the emitter, which includes geometric axis C and perpendicularly intercepts, for example, the external side 16.
    [0045] Since the outlet basin is symmetrically formed on the outer side 16, it may be required to adjust the orientation of the emitters that are installed in a tube so that all emitters are fitted to the tube with, for example, their basins outlets oriented on a similar side. This orientation adjustment can be aided by steps 78. In addition, it may be required to predetermine a position of a medium 77 (schematically illustrated in Fig. 5B) configured to create openings 76 through the tube wall 23 during the production of a tube including drip emitters according to the modalities of the present invention.
    [0046] Such a predetermined position of the medium 77 can be chosen to also be laterally spaced away from the geometric axes C of the emitters that are installed in the tube, and / or also from a central longitudinal geometric axis L of the tube. An orientation means 77 to be placed away can assist in creating openings 76 at locations along the tube that are substantially formed in more central positions of the emitters' outlet basins. Possibly, this more central position may aim to be generally in a lateral center of each basin 20 generally equally spaced from the flanks 17, 19 - in order to increase the probability of effective formation of openings in a lateral location above the outlet basin in cases where, for example, lateral movement of the tube (with emitters) occurs due, for example, to the tube twisting. The alignment between the first and second members 12, 14 to ensure that all flow paths 18 are located, for example, on the same side side as, for example, step 78, can be accomplished by means such as optical means identifying, for example, the exit location 32, the hole 70 and / or the hole 72 and therefore affecting the correct assembly between the first and second members 12, 14 of the emitter 10. The medium 77 can be any medium configured to make openings or cuts through a tube, such as a drill, laser array, cutting array, or the like. Openings 76 formed through the tube can be of any shape such as a circular hole, an ellipse, a slit or cut (etc.).
    [0047] As an example, membrane 30 can be formed from a thermoset elastomeric material such as silicone, EPDM or similar. The first member 12 that connects to the tube can preferably be formed from the same material as the tube to ensure connection. Typically, drip irrigation tubes are made of polyethylene and thus the first member 12 can preferably also be formed from polyethylene. In embodiments where the tube can be made from a different material such as polypropylene, the first member 12 can therefore also be formed from polypropylene. The second member, on the other hand, can be formed from any plastic material such as polyethylene, polypropylene PA, PBT, PET, POM (or similar) since it may not be essential that it be formed from the same material in modalities such as those shown here where it connects to the first member 12 by tight fitting by pressure.
    [0048] In one embodiment, the second member 14 is made from material that is harder, more resistant than the first member 12 so that the teeth 44 can be formed from a material better suited to keep the fit tight by pressure against forces acting to separate members 12, 14 from their interengage. For example, member 14 can be made from one of: polypropylene, PA, PBT, PET, POM while the first member is made from polyethylene.
    [0049] Attention is now directed to Figs. 6A and 6B showing another embodiment of a transmitter 100 according to a form of the present invention. Emitter 100 is generally similar to emitter 10 previously discussed with generally similar elements being indicated here with the same numbers as before. Some elements of issuer 100 that differ in, for example, their construction or arrangement in issuer 10, will now be observed, and will receive new numbers. The emitter 100 on the outer side 116 which is adapted to attach to the tube includes a flow path 118 extending from a beginning 26 to an end 28. Flow path 118 has a first section 1181 extending longitudinally to the along substantially the entire edge 22 and a subsequent second section 1182 extending along side edge 27 and a third short end section 1183 extending along a short edge portion 24 in an opposite longitudinal direction.
    [0050] Pressurized liquid in the tube enters the emitter 100 via the slits 36 formed in the second member 14 and from where the liquid flows via the ducts 66 formed in the first member 112 of the emitter 100 into the channel 68. From the channel 68 liquid flows upwards via hole 70 to the beginning 26 of flow path 118. The liquid flowing downstream via flow path 118 reaches the end 28 from where the liquid can flow back down via the hole 72 into the pressure regulator chamber 58 of the emitter 100.
    [0051] At the emitter 100 a substantial outlet basin length 200 along the geometry axis G will stretch laterally between the flanks 17, 19 which are located, respectively, adjacent to the first section 1181 of the flow path and the edge 24 while that a small area of the outlet basin 200 adjacent to outlet 32 has, for example, a smaller side width limited between the first and third sections 1181, 1183 of the flow path. The emitter 100 by including the second and third flow path sections 118 embodies a possible optimization of the arrangement of cavities for liquid on the outer side 116. This arrangement can be seen as being aimed at by one side having a relatively smooth flow path. long, here embodied as having across all three sections 1181, 1182, 1183 groups of opposing deflecting teeth 21 to create high resistance to liquid flow, while still maintaining relatively large outlet bowl portion 200 with such a large lateral extension as possible.
    Consequently, the emitter 100 has a first longitudinal member 112 with an outer side 116 for attachment to a tube and an inner side 48 that includes a pressure regulating chamber or cavity 58. Chamber 58 is formed adjacent to a longitudinal end of the emitter and the flow path 118 extends along the outer side 116 from its beginning 26 to its end 28 where it communicates with the chamber 58 via hole 72. The beginning 26 is preferably adjacent to the other longitudinal end of the emitter to increase as much as possible an effective length of the flow path and the flow path thus extends in this embodiment along a complete length of only one edge 22 on the outer side 116.
    [0053] Attention is now directed to Figs. 7A and 7B showing yet another embodiment of a transmitter 1000 according to another form of the present invention. The emitter 1000 is generally similar to the emitter 100 with the addition of a first section 11800 of a flow path 1180 of this modality extending along edge 25. The emitter 1000 on its external side which is adapted to be attached to the tube includes consequently, the flow path 1180 extends here from a start 26 adjacent to where the edges 24 and 25 meet. The first section 11800 here consequently extends laterally along edge 25 to where edges 25 and 22 meet. A subsequent second section 11810 then extends along the edge to find a third section 11820 extending along the side edge 27 that communicates with a fourth short end section 11830 that extends along a short edge portion 24 in an opposite longitudinal direction.
    [0054] At the emitter 1000 a substantial outlet basin length 2000 along the geometrical axis G will stretch laterally between the flanks 17, 19 which are located, respectively, here adjacent to section 11810 of the flow path and the edge 24 while that a small area of the outlet basin 2000 adjacent to outlet 32 has, for example, a smaller lateral width between sections 11810 and 11830 of the flow path. The emitter 1000 by including the four sections 11800, 11810, 11820 and 11830 of the flow path 118 embodies another possible optimization of the arrangement of cavities for liquid on the external side. This arrangement can be seen as being aimed on the one hand to have an even longer flow path than on the emitter 100 while slightly compromising the size of the outlet basin 2000, but still maintains a substantial portion of the basin 2000 with a large lateral extension extending up to the edge 24.
    [0055] As seen in Fig. 7B, the position of the flow channel 68 on the inner side 48 of the first part 1120 of the emitter 1000 is opposite to that in the previous modalities in order to take the liquid entering through the inlet slits 36 of the emitter via hole 70 into the beginning 26 of flow path 1180 which consequently starts here adjacent to the intersection of edges 24 and 25 (and not adjacent to the intersection of edges 25 and 22 as in the previous embodiments).
