Patent number: 5084282Abstract: A texturing assembly for a machine for forming special brick shapes from extruded slugs of unfired material. The slugs are conveyed forward by conveyor(s) onto an elevator which lifts vertically. This lift pushes the slugs into opposing rollers. The rollers are arranged on opposing shafts spaced to produce vertical indentations in the slugs on 8-inch centers. The edges shaped by the rollers are the 4-inch long textured edges on the finished faces. At a convenient height above the rollers and on matching 8-inch centers are fixed horizontal wires. The cuts by the wires are centered in the indentations made by the opposing rollers. The cut and textured green paver brick rest on top of the slugs captive in the opposing rollers until lifted away by an automatic setting machine.Type: GrantFiled: August 16, 1990Date of Patent: January 28, 1992Assignee: J.C. Steele & SonsInventors: Gerald L. Stuart, Thomas M. Fisher, Charles B. Whittaker

Patent number: 5047192Abstract: Process of manufacturing a cryogenic regenerator including a plurality of channels for conducting a working fluid, including the steps of providing a cylindrical forming member having a longitudinal axis and a plurality of peripheral slots displaced axially and oriented substantially parallel to the longitudinal axis of the cylindrical forming member, or having a continuous spiral peripheral slot of sufficiently small pitch such that the convolutions thereof are oriented substantially parallel to such longitudinal axis; providing epoxy which is relatively flexible upon hardening, loading the epoxy with thermally conductive material for enhancing the radial thermal conductivity of the cryogenic regenerator, and applying the epoxy to the periphery of the cylindrical forming member to fill the plurality of slots or the spiral peripheral slot with the epoxy and to form a radial layer of the epoxy of a generally first radial thickness allowing the epoxy to harden and thereafter reducing the radial thickness of theType: GrantFiled: July 10, 1989Date of Patent: September 10, 1991Assignee: CDC PartnersInventors: John R. Purcell, Raymond E. Sarwinski

Patent number: 5040962Abstract: A female die part has an upwardly opening die cavity for receiving a male die plunger, a supporting surface around the cavity for a porous batt of fibrous reinforcing material overlying the cavity, and a first shearing edge defining the periphery of the opening for the cavity. Peripheral portions of the batt are clamped to the supporting surface, whereupon the die plunger presses portions of the batt into a mold formed between the male plunger and the sidewalls of the cavity to completely fill the mold. A cutter having a second shearing edge cooperates with the first shearing edge to shear peripheral portions of the batt from the portions overlying the die cavity. The shearing edges in cooperation with the die plunger seal the mold to enable injection of reactive chemicals that impregnate the porous batt within the mold.Type: GrantFiled: December 12, 1989Date of Patent: August 20, 1991Assignee: The Dow Chemical CompanyInventors: Douglas P. Waszeciak, Ronald R. Gamache

Patent number: 5030078Abstract: Apparatus for making food product comprising a closed outer shell and a filling is made from a coextruded body. The body advances through a reciprocating cutting head 3 driven by a reciprocating shaft 10. The shaft 10 rotates to drive, through cam means, blades within the head 3.Type: GrantFiled: January 26, 1990Date of Patent: July 9, 1991Assignee: Bernard Matthews plcInventors: Bernard T. Matthews, David J. Joll, David N. Wilson, John H. Barker

Patent number: 4978484Abstract: The present invention relates to a method of and an apparatus for manufacturing biaxially oriented film. A tubular original film which has been extruded by an extruding die is biaxially oriented by heat and air injected to the inside portion thereof being conveyed to nip rolls each having an individual circumferential speed. The temperature of heat to be applied to the film is controlled on the basis of the detected film thickness for the purpose of obtaining a uniform film thickness distribution. Furthermore, the film can be made uniform by adjusting the outer diameter of the bubble-shaped oriented film by adjusting the distance between two sets of nip rolls on the basis of the measured width of the film. In addition, when the thus-oriented film is subjected to a heat treatment, temperature of heat is arranged to be a predetermined temperature as to prevent adhesion of the films.Type: GrantFiled: March 30, 1989Date of Patent: December 18, 1990Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Masao Takashige, Teruyuki Iwai, Hidenobu Takeichi, Yasuo Takai, Yoshinori Sasaki, Masato Masuoka, Yuichi Ohki
