The invention relates to the application of electrically conductive bus bars onto a low-emissivity coating of glass. A method of applying electrically conductive bus bars onto a low-emissivity surface of glass is performed by gas dynamic cold spray method with the aid of a spraying nozzle of a gas dynamic spraying apparatus. The method comprises: providing in the gas dynamic spraying apparatus an estimated bulk weight of a powder, sufficient for spraying the powder over the entire length of the bus bar; moving the spraying nozzle to a beginning point of the bus bar without supplying the sprayed powder into the nozzle, and upon positioning the moving nozzle at the beginning point of the bus bar, supplying the sprayed powder into the spraying nozzle and moving the spraying nozzle with a constant speed from the beginning point to an end point of the bus bar. Upon reaching the end point of the bus bar, the movement of the nozzle is reversed towards the beginning point of the bus bar with a speed greater than the speed of the nozzle from the beginning point to the end point of the bus bar.

The invention relates to removal from the working area of a dust and gas mixture produced by action of a processing tool on the material being processed. The present dust and gas valve is intended to be mounted in an apparatus for processing materials. The dust and gas valve comprises a casing adapted to accommodate a processing tool and to be connected to a system for aspirating the produced dust and gas mixture, and means for directing the dust and gas mixture into the casing. According to the invention said means comprises: a unit for directional supply of compressed air to the working area, and a dust and gas mixture flow guiding element having a lower surface disposed around the working area and streamlined for the dust and gas mixture flow.
