A method for coating a substrate, preferably of glass, with a pyrolyzed transparent, electroconductive layer. The coating is comprised of indium formate, optionally mixed with a powdered or gaseous tin compound or a gaseous organotin compound. The coating layer is deposited upon a hot substrate whereupon it pyrolytically decomposes, forming a layer which is subsequently heat treated in a reducing or an oxidizing atmosphere to optionally enhance the low emissivity and low resistivity of the coating or reduce said low emissivity and low resistivity properties.

A window glass comprising at least one sheet of glass coated with an electroconductive ITO layer, pyrolyzed from powdered components, combined with a flexible plastic material of the PVB, PU, PVC type, with an index approaching more the index of the ITO layer than the index of air, with which the said layer is coated, and a sheet of glass dyed in the mass, with the same color as the ITO layer, and with properties of reduced energy transmission also entering advantageously into the composition of the window glass is provided. The invention particularly applies to the production of heated windshields for automobiles.

A plurality of injector elements are mounted on a frame and within a nozzle above a subjacent support for depositing a layer of pulverulent product on the support. In order to change the predetermined spacing of the injectors, they are selectively connected to a shuttle which is moved by a digitally controlled stepping motor to a predetermined position, after which they are separated from the shuttle. A solenoid mounted on each of the injectors can be activated to frictionally hold the injector at its predetermined position.

The invention relates to a device for the distribution of pulverulent product on a substrate. The device has two walls delimiting a blade-shaped cavity converging toward substrate, a gas injection chamber closed by a plate, pierced with a multiplicity of jets 12 for injecting a gas under pressure inducing ambient air into the cavity substantially parallel to the wall of the cavity which is adjacent thereto which homogenizes the pulverulent gas product mixture and accelerates it in the direction of the substrate, thus forming a uniform thin layer on a substrate.

Distribution of a pulverulent solid

The invention relates to coating a heated substrate, particularly glass, by a process according to which a distribution nozzle ending in a slot, sprays a gas stream mixed with a pulverulent or powder product, which decomposes in heat, onto a heated substrate for contact therewith to form a thin coating layer thereupon. The coating zone in the vicinity of the main stream of gas-entrained powder coming from the nozzle is cooled to prevent premature decomposition and to directly remove pulverulent products not immediately deposited upon the substrate. Also, a device for carrying out the novel process is disclosed herein. The invention makes it possible to produce a coated glass substrate which is essentially free of the problem of coating fogging.
