Abstract: A dispenser is mounted on an X-Y coordinate arrangement of sleeves and guide shafts. It is driven by a motor mounted to a carriage assembly and having a magnetic follower unit driven by the motor and associated with a cam on a support made of ferromagnetic material, the cam being contoured as determined by the pattern of the gasket to be formed by the deposited gasket material. The magnetic follower unit is magnetically attached to the cam support and includes a wheel which is rotated by the motor and drives itself around the profile of the cam as the gasket material is deposited onto a work path of the workpiece. In one embodiment the cam is a chain and the drive wheel is a sprocket gear operating on the chain.

Abstract: As a liquid is sprayed onto a sheet, some of the liquid is oversprayed beyond an edge of the sheet. A collector for collecting such overspray comprises a pan arranged below the edge of the sheet, and a vapor-retaining structure extending over the pan to define a plurality of narrow apertures which permit the overspray to pass into the pan, while resisting the passage of vapors upwardly through the apertures and back into the spray chamber. The vapor-retaining structure comprises a plurality of inverted V-shaped strips which are arranged parallel to one another such that the bottom edges of adjacent strips define the narrow apertures, the width of the apertures being in the range of about 1/32 to 1/4 inch. This apparatus can be used as a hazardous waste minimization effort for spray coating operations.

Abstract: A paint applicator comprises a frame with a flat side which carries an absorbent pad; the other side of the frame supports a handle. The axles for a pair of rollers depend from a hinged mount supported on the handled face of said frame; the axles are parallel and are inclined toward one margin of the frame. The angle of the hinged mount with respect to the frame is adjustable. The rolling face of the rollers may have a circumferential groove such that, in use, the applicator may edge the paint on a surface adjacent a narrow moulding with a circumferential groove of the rolling surface of the rollers abutting the bevelled corner of the moulding. In another embodiment, the rollers have a knife-edged rolling face which abuts in the inside corner between the surface to be painted and the moulding. In a further embodiment, the rollers are replaced with a stationary knifed-edged abutment which is also intended to abut the inside corner between the surface to be painted and the moulding.

Abstract: The invention is a spray coating machine for applying a protective coating to a pipe or pipeline as the machine travels down the pipe. The invention has a two piece yoke which separates at the top and bottom to enable it to be fitted around the pipe. Each of the two pieces of the yoke serve as a track on which a spray gun moves, one spray gun flexibly mounted on each of the two pieces of the yoke. The two spray guns are aimed at the pipe and are moved up and down opposite each other by means of a gear belt driven mechanism. The spray guns are controlled so that they spray during only one direction of travel and are turned off as they travel in the opposite direction.

Abstract: An application device capable of very rapidly applying a liquid in the form of a thin film to a continuously moving flexible carrier in such a manner as to avoid corrosion and wear to the surface of the doctor edge portion of the application device to thus avoid the formation of streaks on the surface of the applied liquid. A clearance between the surface of the carrier and the surface of the doctor edge portion is made larger at the downstream end of the surface of the doctor edge portion than at the upstream part thereof. For this purpose, a support roller is provided near the downstream end of the surface of the doctor edge portion so that the clearance between the surface of the doctor edge portion and the surface of the carrier can be appropriately controlled along substantially the entire width of the doctor edge portion by adjustably displacing the roller.

Abstract: An overspray extractor collects the overspray of a volatile organic compound coating material sprayed onto three-piece steel cans. The overspray extractor comprises a hood having five orthogonal walls, with the bottom wall having a slot of predetermined width that is placed above the cans and downstream of the coating material nozzles. The ratio of the height of the hood between the top and bottom walls to the width of the bottom wall slot is greater than one. The hood is connected by means of a throat located opposite an outside wall to an exhaust passage. When a vacuum is applied to the hood, coating material overspray and atmospheric air are drawn into the hood through the slot and through the hood into the exhaust passage. A slit in the outside wall permits atmospheric air to be drawn into the hood to flow along and scrub the top wall of solids from the coating material that coagulate on the top wall.

Abstract: An improved method for making preforms by vapor deposition soot laydown processes is provided wherein an oxidizing atmosphere is used during at least part of the laydown process, e.g., during the laydown of the center portion of the preform. The use of such an atmosphere has been found to result in enhanced dopant capture, reduced axial trends, and an overall stabilization of the laydown process. A method for selecting burner flows which optimize the laydown process is also provided.

Abstract: An arrangement for holding and cooling bearing shell blanks (2) positioned one next to the other during a coating process in a vacuum chamber, has cooling body and work piece holding pairs (3) which are detachable from each other and which are connected to one another via a cooling surface (9) and a heat transmission surface (7). A work piece holding part (5) of the cooling body and the work piece holding pair (3) is implemented so that the bearing shell blanks (2) are placed in a concave bearing surface (32) of the holding part during the coating process and are kept, over their entire surface, at a temperature determined by the cooling surface temperature. A temperature gradient can be formed if teflon foil strips are placed on the bearing surface. These allow only a direct heat contact of the apex of the bearing shell blanks (2) with the bearing surface.
