Patent number: 6375451Abstract: A tape casting machine has a casting base with a feed location lying generally in a horizontal plane, and a casting head positioned to dispense a slurry onto the casting base. The casting base and the casting head are movable relative to each other. The casting head includes a reservoir containing the slurry, and a doctor blade having a lower leading margin contacting the slurry in the reservoir and disposed adjacent to but not contacting the casting base. The slurry exits from the reservoir to the feed location of the casting base between the lower leading margin of the doctor blade and the casting base to form a cast tape. The lower trailing margin of the doctor blade has a curvature in the horizontal plane and/or a vertical plane.Type: GrantFiled: August 23, 2000Date of Patent: April 23, 2002Assignee: The Boeing CompanyInventors: Klaus Robinson, Anna Lackner, Elena Sherman

Patent number: 6343924Abstract: The invention relates to an arrangement for the manufacture of plastic molded parts such as sheets, strips or the like which allows the continuous manufacture and largely ensures the avoidance of wastes. The arrangement according to the invention includes two revolving conveyor belts (9, 10) running parallel to each other and arranged at a distance of each other, sealed along their longitudinal edges by adjustable sealing members (16). A liquid plastic material, which is evenly distributed across the entire width of the conveyor belts (9, 10) is fed into the intake gap between the conveyor belts (9, 10) by a distributor means (6) comprising at least two containers (2) holding a monomeric component. The conveyor belts are placed in a chamber (22) in which the temperature required for solidification or polymerization of the liquid plastic material is achieved by heating means (25) while transported by the said conveyor belts (9, 10).Type: GrantFiled: May 26, 1999Date of Patent: February 5, 2002Assignee: Firma Ploytech Klepsch & Co. GmbHInventor: Rudolf Klepsch

Patent number: 6312244Abstract: A plant is provided for manufacture of latex foam products comprising recesses, such as mattresses, cushions and the like. The plant makes use of a plurality of carriers placed in a ring-like configuration limited by a first, upper stretch between a foam injecting station and a product-removing station and by a second lower stretch for the return of the carriers devoid of foam, to the injecting station. At any moment the first stretch is filled with carriers, touching each other and making a single mold on which foam is injected, while on the second stretch, at least one carrier, or a discrete number of carriers, considerably separated form one another, travel. The carriers of the first and second stretch are moved by different and independent operating systems and the speed of the carriers in the second stretch is considerably higher than the speed of the carriers in the first stretch, so that, a carrier can always be present at the injecting station, while another carrier leaves the removing station.Type: GrantFiled: March 8, 2000Date of Patent: November 6, 2001Assignee: Sapsa Bedding SpAInventors: Guido Levera, Francis Herlin

Publication number: 20010028909Abstract: A method and apparatus for making a shaped confectionery product of Bingham plastic rheology by cold extrusion wherein particles of the confectionery product are fed between counter-rotating form rolls having depressions corresponding to the desired product shape. The particles are compacted and compressed between the form rolls and fuse together to exit with a thin web of material interconnecting the shaped confectionery product. The release of the product from the roll surface is aided by induced differential motion between the rolls.Type: ApplicationFiled: June 7, 2001Publication date: October 11, 2001Inventors: Peter Thomas Kashulines, Emil Anthony Kritzer, Robert Otto Brandt, Aubrey Elmo Jones, Malcolm Albert Austin, Ray Louis Peterson

Patent number: 6268005Abstract: An improved sheeter wire device providing constant tension on a feeder spool even during wire breakage. A constant speed motor draws wire across the face of the sheeter while a drag motor maintains constant tension on the wire. A pair of pinch rollers prohibits unwinding of the feeder spool in the event of wire breakage.Type: GrantFiled: August 4, 1999Date of Patent: July 31, 2001Assignee: Recot, Inc.Inventor: Marvin Vincent Brewer

Patent number: 6213755Abstract: A process and apparatus is provided for automatically and continuously producing a mass of moldings. A continuous molding is manufactured by injecting a solid solution in order of precedence into a plurality of molds circulating in a line along an endless track and by solidifying the injected solution. The solution is preferably vinyl chloride resin or another synthetic resin. After the solution solidifies the mold is automatically removed from the molding. The continuous molding consists of a number of moldings open at the bottoms and connected end to end by a top plate, molded at the same time.Type: GrantFiled: December 1, 1998Date of Patent: April 10, 2001Assignee: Kabushiki Kaisha KatsuronInventor: Hiroshi Ishikawa

Patent number: 5935536Abstract: Apparatus and method for reclaiming expanded synthetic resin wastes in a form suitable for subsequent injection molding. The apparatus includes a tank containing a solvent having a pump for pumping dissolved resin wastes to an evaporator. The evaporator comprises an endless belt on which dissolved resin waste is deposited and precipitates in the form of a thin film. A heater is disposed below the belt to expedite separation of solute and solvent by evaporation. A blower disposed within a housing enclosing the endless belt establishes air circulation over the belt, further promoting evaporation. The thin film is wound on a roller and subjected to a heated roller to fuse the many thin film strata into a solid, generally cylindrical mass. The solid mass is then comminuted by a granulator. Evaporated solvent is recovered in a condenser and is reused.Type: GrantFiled: January 14, 1998Date of Patent: August 10, 1999Inventors: Berkley C. Badger, Kevin E. Hissem, David E. Jones
