Patent number: 5360516Abstract: This invention relates to the treatment of substrates with fluidized material in repetitive patterns during application cycles. The treatment patterns made with this invention can be altered by changing machine operating parameters. The patterns of fluidized material are applied to substrates using intermittent charges of compressed air. The intermittent charges of compressed air pass through a venturi slot which creates a region of low pressure in the charges adjacent to a region where the fluidized material accumulates between application cycles. This region of low pressure helps to entrain the fluidized material in the charge of compressed air. After the fluidized material is entrained in the charge of compressed air, the charge deposits the fluidized material on the substrate.Type: GrantFiled: November 12, 1992Date of Patent: November 1, 1994Assignee: Philip Morris IncorporatedInventors: Edwin L.

Patent number: 5246731Abstract: A method and apparatus for depositing solder on the terminal pads of printed circuit boards in which a solder resist layer or layers having a thickness corresponding to the desired solder height border the pads. Molten solder from a reservoir is directed by nozzles against the sides of the board to fill the cavities extending above the terminal pads while the board is moving via a conveyor mechanism relative to the reservoir. The cavities when filled with molten solder are covered by a suitable element such as a flexible belt or roller. The molten solder within the covered cavities is then cooled below its solidification point and the covering element removed. If desired, part or all of the solder resist layer or layers may then be stripped from the board to leave solder pads extending above the surface of the board.Type: GrantFiled: March 16, 1992Date of Patent: September 21, 1993Assignee: Velie Circuits, Inc.Inventor: Larry N. Velie

Patent number: 5229166Abstract: A method of forming a gummed band on a web of paper (1) is provided. A marginal band (7) forming a seam is projected by one (10) of two devices (10, 11) under the action of compressed-air pressure, the air being pre-heated (20) and passing into a feed line (19), whereas an inside gummed band (6) is formed by the other device (11) fed with cold compressed air through a duct (21). An adhesive is contained in a reservoir (8), kept under pressure by means of a tube (12), and reaches the projection device through another duct (9).Type: GrantFiled: July 31, 1992Date of Patent: July 20, 1993Assignee: Fabriques de Tabac Reunies, S.A.Inventors: Michel Grossmann, Eduard Ringgenberg

Patent number: 5215622Abstract: The invention is used in a labeling machine for applying liquid to the surface of the bottles after the labels are applied for the purpose of rendering scratches, abrasions, chipping and chafing of the bottle surfaces invisible. To minimize the space taken by the combination of the labeling machine and the new liquid applicator device, the device is associated with the outfeed starwheel of the labeling machine. The liquid applicator device includes a fixed arcuate friction and applicator surface on which the bottles roll by reason of being orbited in the outfeed starwheel and, while rolling, the bottles receive their coating of liquid from the applicator surface. The applicator surface is spongy and maintains a coating of the liquid on it which is applied to the surface by means of spray nozzles which are timed to spray the applicator surface by projecting a fanshaped spray through the space between successive bottles as the bottles are moving orbitally by the rotating outfeed starwheel.Type: GrantFiled: March 2, 1992Date of Patent: June 1, 1993Assignee: Krones AG Hermann Kronseder MaschinenfabrikInventor: Stephan Schmelzer

Patent number: 5194297Abstract: A particle deposition system having an atomizer, wafer transport, sheath flow means, particle counter and computer control for accurately depositing a desired density of particles onto a surface. The sheath flow keeps an article clean, while the particle flux in the deposition chamber is rising from zero to an equilibrium state. The particle counter measures particle flux by sampling the atmosphere in the deposition chamber. The computer determines when the rate of change of particle flux is substantially zero and then actuates transport of the article completely or partially out of the sheath flow into the mist of falling particles. The computer also calculates the required deposition time for providing the article's surface with a desired particle density, actuating transport of the article back into the sheath flow after the desired density is reached. The operator of the system can specify particle size, desired density and full or partial coverage of the surface with particles.Type: GrantFiled: March 4, 1992Date of Patent: March 16, 1993Assignee: VLSI Standards, Inc.Inventors: Bradley W. Scheer, Paul A. Konicek

Patent number: 5178902Abstract: Two methods are provided for applying and forming a protective composite coating on a metallic substrate. In the first method, the substrate is heated to a temperature between about 175.degree. C. and 275.degree. C. and a powdered coating of epoxy resin between 100 and 400 microns thick is applied to the outer surface of the heated substrate. A premixed powder coating of epoxy resin and polyolefin is applied directly onto the epoxy resin coating, forming an interlayer of interspersed domains of epoxy and polyolefin between about 100 and 400 microns in thickness. On to this, powdered polyolefin is sprayed to produce a polyolefin sheath coating for the metallic substrate between 200 and 1000 microns in thickness. In the second embodiment of the method, the interlayer is formed by spraying pure epoxy resin powder and polyolefin powder from separate sources simultaneously onto the substrate. By these methods, a metallic substrate coated with a composite epoxy/polyolefin protective coating is produced.Type: GrantFiled: August 7, 1991Date of Patent: January 12, 1993Assignee: Shaw Industries Ltd.Inventors: Dennis Wong, Jiri Holub, Joseph G.
