    The invention relates to a nozzle for continuous deposition on a substrate.
    a layer of solid material / glass) as a result of the reaction of at least two reactants, gaseous or suspended in a gas.
    The purpose of the invention is the expansion of technological capabilities to ensure the possibility of obtaining a homogeneous mixture of gaseous media.
    FIG. 1 shows a nozzle, a cross section; in fig. 2 - the longitudinal end of the nozzle, the cross-section; in fig. 3 shows section A-A in FIG. ..
    The nozzle for applying a layer of solids to the substrate contains the node 1, the feed, the node 2 of separation and the node 3 of distribution, whereby the node 1 of feed and the node 3 of distribution are elastically attached to the node 2 of separation with screws 4, pressed (their disc washers 5. Between the assembled nodes 1 - 3 are located seals 6.
    The nozzle feed unit 1 comprises three chambers 7-9, extending along the nozzle and each of the inlets 10. In FIG. 1, only the inlet 10 of the chamber 8 is shown, since the remaining inlets of the chambers 7 and 9 are longitudinally offset to secure the corresponding supply lines (not shown).
    The separation unit 2 comprises a plurality of vertical channels 11 communicating the chambers 7-9 with the separation unit 2.
    At the entrance and exit of the vertical channels 11 are placed, the pads 12 of the sponge with open pores from the terlon. These gaskets 12 serve to create large pressure losses designed to evenly distribute gases along the entire length of the nozzle. Distribution element 3 contains two profiles 13 and 14, the cross sections of which are made in the form of a rectangular trapezium and are located symmetrically relative to the vertical plane of the nozzle the acute angles of these cross sections are adjacent to this median plane.
    The inclined surfaces of these two trapezoids form a prismatic space 15 between them, the third side of which is covered by the bottom surface of the separation element 2. Outputs of all three parallel channel groups
    11 exits into the lower surface part of the separation element 2 forming the prismatic space 15.
    The nozzle for applying a layer of a solid substance to the substrate also contains three adjacent chambers 16-18, which are designed to receive gaseous media and have corresponding outlet openings adjacent to one another and converging to
    a common mixing zone for gaseous media located along openings 2 along the stream. The outlet openings of chambers 16-18 are formed by longitudinal slits made in the truncated apex of the prismatic space 15, and the adjacent outlets of the chambers 16-18 are separated by two intermediate ribs formed by the edges of two corresponding metal bands 19 and. 20, located along the entire height of the prismatic space 15. The volumes of the three chambers 16-18 are equal, and the belts 19 and 20 are positioned so that each chamber 16-18 will communicate through one of the groups of vertical channels 11 to chambers 7-9, respectively. The chambers 16-18 are separated from the corresponding chambers 7-9 tightly by means of seals 21 and 22 placed in the longitudinal grooves 23 and 24, into which one of the ribs of the tapes 19 and 20 are inserted.
    Two clamping strips 25 and 26 fixed by screws 27 press the corresponding seals 21 and 22 in the grooves 23 and 24. In connection with this, the ribs of the belts 19 are thus secured between the edges of the grooves 23 and 24 and the seals 21 and 22.
    An oil circulation line passes through the nozzle, inlet port 28, which is shown along with two longitudinal circulation channels 29 and 30, made in profiles 13 and 14 COOT. The oil circulating line communicates with the external system of the thermal stabilization of the nozzle in order to maintain its temperature, approximately 110 ° C. In addition, the nozzle is provided with support surfaces 31 and 32, intended to give the tapes 19 and 20 corresponding angles of inclination and installed adjacent to each end of the tapes 19 and 20, which divide the prismatic space 15 into three equal volumes, and means of longitudinal tension of the metal tapes 19 and 20. The opposite ends of the belts 19 and 20 rest on two guides, identical surfaces located at the other end of the nozzle. The supporting surfaces 31 and 32 are fixed perpendicular to the two walls 33 and 34, respectively, located in the continuation of the nozzle body.
    . The longitudinal tensioning means of the belts 19 and 20 comprise a rod 35 with a thread 36 placed at one of its ends, clamping devices 37 and 38 for clamping the ends of the respective belts 19 and 20, attached screws 39, a sleeve 40 with an outer 9 LINT thread 41, mounted on the other end of the rod 35 is a nut 42 and a spring 43 placed between the nut 42 and the sleeve 40, the sleeve 40 being mounted on the rod 35. The sleeve 40 is screwed into a plate 44 attached to both walls 33 and 34 located in the extension of profiles 13 and 14 and carried | Sim support surfaces 31 and 32. The threaded holes into which the sleeve 40 is screwed are inclined relative to the vertical plane passing through the vertex of the prismatic space 15 and form an angle to this plane, so that the angle of this angle is predominantly at the level of the supporting surfaces 31 and 32. The sleeve 40 is rigidly fixed outside the space between walls KSLtm 33 and 34 and plate 44.
    The nut 42 for adjusting is screwed onto the outer end of the rod 35, the spring 39 in the form of cup springs, and the washers are located between the sleeve 40 and the nut 42 to prevent the adjusting nut 42 from untimely rotation.
    A triangle-shaped part 45 screwed onto the end of the distribution element 3 is located between the supporting surfaces 31 and 32. and serves to close the end of the prismatic space 15.
    Taking into account the tension force and the angle at which it acts on the ends of the belts 19 and 20, the latter are tightly pressed to the supporting surfaces 31 and 32 and in the transverse plan. Acquire the inclination of the supporting surfaces 31 and 32. Considering that the accuracy of the supporting surfaces can achieve a high degree particularly in regards to
    the inclination and centering of the truncated top of the prismatic space 15, pressing the belts 19 and 20 to the surfaces with a certain tension allows keeping the same position strictly along the entire length of the nozzle, as a result of which the gap between the three ka, measures 16-18, is made between the ribs profiles 13 and 14 are kept uniform regardless of expansion due to the elastic tension forces acting on the belts 19 and 20.
    The nozzle is also provided with supporting stubble si 46, cantilevered with one end and in contact with metal tapes 19 and 20 with other ends.
    The rods 46 pass through profiles 13 and 14 parallel to the surfaces of their cross sections in the form of a rectangular trapezium and preferably half a distance from these two surfaces. The rods 46 are designed to act on the ribbons 19 and 20. The cross-sectional durability of the ribbons 19 and 20 cannot be perfect, as they are necessarily obtained with a cutting path. The cutting forces that occur during this operation create a slight lateral deformation of the belts 19 and 20. The tension applied to the belts 19 and 20 increases. This deformation between the two support surfaces 31 and 32, together arcuate in the transverse plane of the belts 19 and 20. The rods 46, distributed along the entire length of the prismatic space 15, are intended to be affected by the protrusions of the belts 19 and 20, which are oriented in this way so that the convexity faces the rods 46. The light force of the rods 46 into the middle of the belts 19 and 20 allows the flatness of the ribbons to be restored in the transverse plane without disturbing the straightness of the free edge of the belts 19 and 20 stretched on both onts.
    Special care must be given to the finishing of the parts that make up the prismatic space 15 and the belts 19 and 20 separating this space, in particular as regards the state of the surface of these parts in order to guarantee the laminarity of the flow with its tangential character in gas jets up to they meet at the top of the prismatic space 15, where the reaction should take place and where the substrate to be covered is located. In addition, all surfaces in contact with gaseous reagents must be made of a material resistant to the corrosion caused by these gases. All surfaces, including the ribbons 19 and 20, are gold plated by electroplating. The nozzle for applying a layer of solids to the substrate works as follows. Gaseous or suspended solids in the gas are delivered to the delivery unit 1, where they are distributed in chambers 7-9, then to separation unit 2 along vertical channels 11 and then to distribution node 3, where, the passage to chambers 16-18, the reactants arrive at the outlet openings of these chambers and come into contact with each other in close proximity to the substrate of a layer of solids (glass), brought to a temperature close to the reaction temperature of these reactants. The proposed glass is intended for the manufacture of self-moving front windshields or rear windows; vehicles, namely automobiles, since it is impossible for them to use glasses that are opaque or insufficiently transparent or in which uneven metal oxide coatings can impair visibility for the driver. When the icing of such glass is eliminated by passing an electric current in the metal layer covering it, the voltage drop due to the electrical resistance of this layer should be minimal, since the electric current must be supplied by a battery with low power and low voltage (12 V). Tests carried out with such a nozzle allow the cut to be performed with satisfactory quality and uniformity. 2 3
