Abstract: The invention relates to a glass product with electrically heated surface and a method of its manufacture.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to methods for processing glass objects, in particular, to methods of blunting sharp edges of glass objects. A method comprises treating a glass edge with a focused laser beam, while relatively moving the glass object and/or the beam, said treating of the glass edge being carried out with a laser beam having a ring-shaped section, during which the glass edge is heated with the laser beam to a temperature above glass transition temperature, T>Tg. The method provides the creation of tempered glass sections of desired shape and size in the near-edge area due to the provision of thermal stresses in these areas, which cause the formation of a chamfer with rounded or blunt ends on the glass at brittle fracture.
