Patent number: 4837281Abstract: The invention is specifically concerned with an improvement in the process of manufacturing reinforced materials. The reinforced materials are conceived to include a wide variety of materials, the most notable being high density compressed gaskets. The improvement comprises mixing a cut solid (generally a cut fiber) with a body material to produce the reinforced materials. The solid is cut into particulates of highly variable size, the range in the size of the particulates being adjusted to optimize the characteristics of the resulting reinforced material. The cut solid is produced utilizing comminuting machines previously used for the recycle of waste products.Type: GrantFiled: June 9, 1986Date of Patent: June 6, 1989Assignee: BASF CorporationInventors: Billy B. Hibbard, Joe A. Mann, Frans P. P. Koeleveld, Agnes K. Potepan, Richard E. White, Barry T. Knight, Howard H. Bryant

Patent number: 4813319Abstract: An apparatus and improved method for transversely cutting strips of deformable material with a rotating cutting blade which is moved generally transversely across the strip at a predetermined rake angle and bevel angle. A vacuum applied to certain chambers of a platen draws the strip firmly against a supporting structure at two locations on opposite sides of a cutting line during the cut cycle. A lubricant is sprayed through nozzles onto the blade as it cuts the strip and blow-off nozzles remove excess lubricant during the cut and return cycles of the blade to prevent contamination of the cut strip edges. A release bar assists in disengaging the strip from the platen after the strip is cut. Grippers remove the cut strip and then an input conveyor advances the remaining strip toward the cutting line where the grippers pull the strip forward to a predetermined position for the next cut cycle.Type: GrantFiled: April 1, 1987Date of Patent: March 21, 1989Assignee: The Firestone Tire & Rubber CompanyInventor: Harley P. Weyand, Jr.

Patent number: 4590829Abstract: A food slicing method and apparatus includes blades mounted on a shaft for rotation therewith, the blades successively converging and diverging to slice the food pieces as the shaft rotates. An inlet flume conveys the food pieces to and through the rotating blades. A flighted conveyor within the flume submerges the food pieces at the flume inlet and releases them at the bottom of the flume to float upward, oriented according to their buoyancy before entering the blades. In one embodiment, the blades are mounted on a curved shaft which rotates about a longitudinal axis of symmetry to cause the blades to converge on the inward side of the shaft and diverge on the outward side. The blades engage a synchronously counterrotating drum to slice the food pieces as they enter on the inward side of the shaft. As the blades diverge, the majority of the slices fall free of the blades.Type: GrantFiled: June 15, 1984Date of Patent: May 27, 1986Assignee: Amfac Foods Monterey, Inc.Inventors: Arthur R.

Patent number: 4404879Abstract: An "easy open" feature for a sealed flexible pouch and method and apparatus for accurately positioning said feature in the sealed border region of said flexible pouch. The feature comprises a stress concentrating aperture exhibiting a strong tendency to initiate a directional tear while maintaining integrity of the sealed pouch until an opening force is applied. In a preferred embodiment the pouches are cut from a moving web by a rotary shear cutter while a web punching means operatively connected with each cutter blade is engaged in the moving web. Because the web undergoes no movement relative to the cutting means or the punching means until both operations have been completed, the aperture is precisely positioned with respect to the severed edge of the pouch. In a particularly preferred embodiment, the sealed edge of the pouch is subjected to a high level of tension and is unsupported in the area of contact with the punching means during the aperturing operation.Type: GrantFiled: March 11, 1982Date of Patent: September 20, 1983Assignee: The Procter & Gamble CompanyInventors: Arthur E.
