Abstract: The invention relates to a coating system in the form of a vehicle (3), which can travel in a pipe (1) or a duct. The coating system is pulled over an appropriately stabilised section of piping (4) in such a way that the inner wall (58) can be evenly coated by a rotating distributor (18) with an outlet opening (29). The various product and supply lines (20, 21, 22, 136) are securely accommodated inside the section of piping (4) by means of a highly resistant flexible tube (138) into which they are drawn. Said flexible tube is air-tightly sealed by covers (148, 149) or a terminal block (150) at the ends and is also configured to absorb tensile forces. The individual supply and product lines (20, 21, 22, 136) are thereby protected in the section of piping (4) without being subjected to excessive pulling or other forces. They are also prevented from interfering with each other.

Abstract: A system and method for controlling triggering of spray guns in an automatic spray coating system, includes a hand-held pendant having input controls for entering spray gun “on” and spray gun “off” control parameters based upon observation of parts as they are conveyed past the spray guns by a conveyor. Gun triggering controls for optimized spray patterns, including extended and restricted spray patterns and combinations thereof, are entered and saved in a gun triggering controller according to an operator's inputs which include START SPRAY, STOP SPRAY, SAVE and SET PICKOFF controls. Multiple gun control parameters are stored as unique part coating recipes in the controller and are executable in look-ahead sequence based upon part identification as parts are conveyed toward the spray guns. The multiple gun control parameters are calculated by the controller from a fixed Pickoff distance from a part identification sensor to the spray guns.

Abstract: Disclosed is a method and apparatus for coating liquid films on to the surface of a wafer substrate by rotation the substrate at a speed sufficient to cause a liquid, through centrifugal effect, to flow outwardly toward the perimeter of the surface and form a substantially uniform thickness liquid coating thereon and starting at the central region of the wafer surface and moving radially outward therefrom, spraying a fine mist of the liquid to the surface of the wafer.

Abstract: The invention relates to a device for powdering printed sheets, especially printed sheets made out of paper, whereby a powder coating device is arranged inside a sheet feeding device and an electrostatic charging device that is disposed outside the sheet feeding device is assigned to the sheet.

Abstract: Provided, among other things, is a re-circulating particle feed apparatus comprising: a circular conduit of dimensions suitable for circulating gas with suspended particles; a deposition station comprising an opening onto the conduit, into which opening an electrostatic chuck fits, with a deposition surface of the chuck available to the interior of the conduit; and a propulsion device for maintaining fluid and particle circulation through the conduit, wherein the propulsion device is adapted to maintain fluid and particle circulation at a rate that brings a deposition effective amount of particles within a range of electro-attractive influence at the deposition station.

Abstract: Apparatus for depositing granules onto a substrate includes a hopper for containing granules, the hopper having a discharge slot, and a reciprocating gate mounted for rotation across the slot to open and close the slot. A method of depositing granules onto a moving substrate includes providing a hopper for containing granules, where the hopper has a discharge slot. A gate is moved across the slot to open and close the slot. When the slot is open granules fall from the hopper, and when the slot is closed granules are prevented from falling from the hopper. The method further includes detecting the speed of the substrate, and controlling the extent of opening of the slot by the gate to meter the granules falling from the hopper in response to the speed of the substrate.

Abstract: A waste fluid separation and recovery system of the present invention includes a first cup in which the substrate is disposed when the substrate is being coated with the photoresist, a photoresist waste fluid groove connected by a path of fluid communication with the first cup and an exhaust airflow generator for generating an exhaust airflow, which guides photoresist waste fluid from the substrate toward the photoresist waste fluid groove.

Abstract: A thermal spraying system for a cylinder, in which a cylinder is held on a turntable; a bore inside surface of said cylinder is subjected to thermal spraying by moving a thermal spraying gun in the axial direction in the bore of said cylinder while said cylinder is rotated; a suction port of a dust discharge pipe for sucking dust in the bore of said cylinder is disposed under said cylinder to suck and discharge dust in the bore of said cylinder; and the diameter of the suction port of said dust discharge pipe is larger than the inside diameter of the bore of said cylinder.
