Publication number: 20130341817Abstract: A composite article is formed with a reaction-injection mold (RIM) foam layer between a substrate and a flexible skin in a RIM tool having at least one inflatable seal defining an edge of the foam layer. The RIM tool is clamped in a fully closed position. A reactive mixture is injected into a space between the substrate and skin with the inflatable seal being deflated. The inflatable seal is inflated to close off the edge when the reactive mixture approaches the edge. Inflation of the inflatable seal and clamping at the fully closed position are maintained for a gel time of the reactive mixture. After the gel time, the inflatable seal is deflated to vent at least a portion of gas produced by the reaction while maintaining the clamping at the fully closed position for a curing time of the reactive mixture.Type: ApplicationFiled: June 20, 2012Publication date: December 26, 2013Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventor: Steven W. Heffelbower

Publication number: 20080050463Abstract: A stacked type tooling is formed by stacking a plurality of slices. Each slice has a plurality of patterned openings. When these slices are stacked together, The patterned openings form at least a cavity. Unnecessary volume of the tooling can be avoided to shrink the size of the tooling and let the tooling be lightweight. Moreover, the manufacturing cost and time of the tooling can be substantially reduced.Type: ApplicationFiled: August 23, 2006Publication date: February 28, 2008Inventor: Chen-Yang Lin

Patent number: 6103159Abstract: The present invention relates to a method for preventing material to be briquetted from sticking to a roll surface of a briquetting roll press. To be more specific, a sticking of the material to be briquetted to and a sintering of the material on the roll surface are to be prevented. To this end, a lubricant emulsion which is atomized with a gas is sprayed onto the roll surface.Type: GrantFiled: July 17, 1998Date of Patent: August 15, 2000Assignee: Maschinenfabrik Koppern GmbH & Co. KGInventors: Wolfgang Schutze, Werner Plagemann, Siegfried Grone

Patent number: 5547357Abstract: An apparatus for hot-briquetting iron sponge includes a gravity feeder which has a feed shaft and a regulating tongue which supplies material in a dosed quantity to a moulding gap of a roller press, in such a way that the apparatus can also be used for pressing hot iron sponge at temperatures of up to 1000.degree. C. for obtaining high-density briquettes of good quality. The regulating tongue is provided with a heat-reducing insulating layer and cooling system. The feed shaft and a feed hopper also may have a heat-insulation layer and a cooling system. A flow-rate control is provided for gravity feeders where bulk material or flowable material is supplied by at least one regulator through a feed shaft to a moulding gap formed between at least two rolls and is processed by the rolls. At least one of the rolls is motor-driven. The material is supplied to the moulding gap by the regulating tongue in response to a driven roll torque sensed by a torque detector.Type: GrantFiled: May 20, 1994Date of Patent: August 20, 1996Assignee: Maschinenfabrik Koppern GmbH & Co. KGInventor: Hans-Georg Bergendahl

Patent number: 4996743Abstract: An improved drive linkage for a reciprocating mold plate in a food patty molding machine includes, in series, a hydraulic cylinder and its piston; one is connected to a motor or other prime mover and the other to the mold plate. Three hydraulic lines connect the opposite ends of the cylinder to a large hydraulic reservoir and to each other. A hydraulic pressure flow directing means, preferably comprising check valves in the hydraulic lines, produces a continuous, unidirectional flow of hydraulic fluid from the reservoir into one end of the cylinder, on to the other end of the cylinder, and then back to the reservoir; the flow remains unidirectional despite cyclic reversal of the direction of piston movement in the cylinder.Type: GrantFiled: January 29, 1990Date of Patent: March 5, 1991Assignee: Formax, Inc.Inventor: Wilbur A. Janssen

Patent number: 4986747Abstract: In compacting straw and other fibrous material into blocks or briquettes the material is precompressed into a length L of compressed material before feeding to compacting apparatus for compacting the length into the blocks or briquettes.The compacting apparatus includes a pair of rotary members 10, 11 rotatable about relatively inclined axes 12, 13. A row of pockets 19, 20 extends around each rotary member and the pockets define spaces in which the material is received. The rotary members converge during rotation so that the material is compacted in the spaces.Type: GrantFiled: January 21, 1986Date of Patent: January 22, 1991Assignee: Barrico LimitedInventor: Keith Broomhall

Patent number: 4248584Abstract: Highly purified metal halide salts are made into a frangible stick having uniformly spaced lines of weakness which permit the stick to be broken readily into cylindrical pellets of uniform size. The pellets are particularly useful to supply the vaporizable fill in high intensity metal halide discharge lamps. The stick is formed by intermittently loading salt powder into the sized entrance to a channel through which the salt is forced, and compressing the charge against the back end of previously formed salt stick by means of a polished plunger.Type: GrantFiled: February 12, 1979Date of Patent: February 3, 1981Assignee: General Electric CompanyInventor: Elmer G. Fridrich
