Patent number: 5168800Abstract: A method and apparatus for eliminating fat from a formed ground meat product while maintaining desireable texture and other eating qualities, comprising the steps of placing the product on a support member configured to promote the flow of fat away from the product; bringing the product to a temperature at which a substantial proportion of the fat contained in the meat is liquified; and compressing the product against the support member only after the product has reached the temperature at which a substantial portion of the fat contained in the meat is liquified, by applying a rolling pressure which repeatedly traverses the product in a plane parallel to the support member for a period and at a pressure level sufficient to exude a substantial portion of the liquified fat from the product. During at least part of the time when rolling pressure is applied, a non-fat liquid is supplied to the top surface of the product.Type: GrantFiled: June 14, 1990Date of Patent: December 8, 1992Assignee: Geoffrey MargolisInventor: Geoffrey Margolis

Patent number: 5102057Abstract: The present invention is directed toward an apparatus for compressing plastic waste for the purposes of minimizing space, maximizing manageability and otherise improving the logistics of household recycling. The claimed invention is an electrically powered machine that rotates a plurality of converging, tapered cylinders. Each cylinder has chisel pointed teeth arranged in a helical pattern along the surface of each cylinder. Once a piece of plastic material is placed between the cylinders, the motor is turned on. The cylinders all rotate in the same direction. The pointed teeth on the cylinders grab the plastic material, forcing it deeper between the converging cylinders. The rotation of the cylinder, with the protruding teeth, cause the plastic material to twist as it is pulled downward. Eventually, the plastic material is passed through the bottom of the converging cylinders, wherein the plastic material is oriented in a tightly compressed and twisted cylindrical form.Type: GrantFiled: May 20, 1991Date of Patent: April 7, 1992Inventor: William H. Ellis, III

Patent number: 4901103Abstract: A pressure developing device having a pair of pressure developing rollers in an image recording apparatus. A pressure-sensitive recording sheet can be fed to pass between the pressure developing rollers, and has a pressure-sensitive image bearing layer on one surface thereof. A developer sheet can selectively be fed to pass between the pressure developing rollers in superposed relation to the pressure-sensitive image bearing layer. The pressure developing rollers are spaced from each other by a gap which is greater than the thickness of the pressure-sensitive sheet and smaller than the combined thickness of the pressure-sensitive sheet and the developer sheet. The pressure developing device also includes a friction roller held against a surface of the pressure-sensitive recording sheet opposite to the image bearing layer and rotatable for frictionally feeding the pressure-sensitive recording sheet.Type: GrantFiled: June 3, 1988Date of Patent: February 13, 1990Assignee: Brother Kogyo Kabushiki KaishaInventors: Kiyoharu Hayakawa, Yumio Matsumoto, Masashi Ueda, Akira Sago, Osamu Tagaki

Patent number: 4875511Abstract: Apparatus for removing bark from logs, particularly from logs of stringy-bark eucalyts and other rough-barked tree species, and for crushing logs, consists of a plurality of pairs of concave rollers which are mounted in spaced-apart relationship along the linear passage of the log through the apparatus. Each pair of concave rollers applies pressure to regions of the log to loosen the bark from the body of the log. Knives may be included on the concave surfaces of some or all of the rollers to cut the loosened bark.Type: GrantFiled: December 10, 1987Date of Patent: October 24, 1989Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Robin Wingate-Hill, Bernard M.

Patent number: 4693587Abstract: An image forming apparatus wherein an unfixed image is formed on a recording material at an unfixed image forming station, such as an image transfer station or a station for developing an electrostatic latent image. The unfixed image is fixed by a fixing device including a couple of fixing rollers, one of which is substantially frustoconical. The present invention is effective to avoid the possible disturbance to the image caused by the frustoconical shape of the roller. The preferable arrangement is such that the distance between the image forming station and the nip formed between the rollers is shorter than the length of the recording material, and that the nip is non-parallel with respect to the leading edge of the on-coming recording material. Further, the small diameter side of the conical roller receives the leading edge of the sheet earlier than the large diameter side of the frustoconical roller.Type: GrantFiled: July 11, 1985Date of Patent: September 15, 1987Assignee: Canon Kabushiki KaishaInventors: Michio Shigenobu, Takashi Saito

Patent number: 4635861Abstract: A roller mill, in which the milling rollers are pressed together with high pressures, has a fluidic device for imparting the respective pressure. This fluidic device comprises piston-cylinder units and a pressure line for the fluid. In order to obtain a skewing of at least one roller in dependency upon the pressure exerted by the fluidic device, pressure sensitive means are interposed between the pressure line and a displacing device for the skewing angle. In this way, a pressure signal may be transferred to a converter for converting the pressure into a corresponding displacement stroke. Preferably, at least one roller has a basic camber or crown which corresponds to a pressure within a lower range of the occurring pressures.Type: GrantFiled: February 7, 1985Date of Patent: January 13, 1987Assignee: Gebruder Buhler AGInventor: Heinz Resch

Patent number: 4587895Abstract: Radial compression of a cylindrical body made of compressible material, is achieved by axially leading the body through a rotationally symmetrical space, which tapers in the transport direction and whose smallest diameter is smaller than that of the body to be compressed, the envelope of the rotationally symmetrical body being generated by roller shaped bodies which rotate in the same direction and cross the axis of rotation of the space at an angle of between 5.degree. and 45.degree. but do not intersect it. During such passage, the body performs a helical movement relative to the envelope of the rotationally symmetrical space and is compressed, the compression being made permanent by wrapping at the narrowest point of the space.Type: GrantFiled: March 19, 1985Date of Patent: May 13, 1986Assignee: Chemie Linz AktiengesellschaftInventor: Wilfried T.

Patent number: 4509571Abstract: A wooden truss structure comprises upper and lower chords, each of which is grooved on the side facing the opposite chord. A web member formed of sheet material, such as plywood, interconnects the chords and fits within the chord grooves. At the web/groove interface, the webs are scalloped to provide alternating alignment guide areas and glue vent areas which extend above the interface and allow the escape of excess glue from the groove. The scalloping, in addition to venting the glue line, forms individual, pressurized glue pockets which assure even glue distribution. The scalloping is preferably provided by pressing the wood web material to compress it at the glue vent areas and thus permit the web member, due to its memory, to expand after contact with the glue. This expansion pressurizes the glue pockets and forces glue from the joint area into the wood further enhancing the expansion process. The web is rigidly bonded to the chord members, all while being aligned by the alignment guide portion.Type: GrantFiled: June 23, 1982Date of Patent: April 9, 1985Inventor: Dierk D. Peters

Patent number: 4348952Abstract: A mechanism for inducing a crossing of one axis of a roll with respect to the axis of a second roll on a calender roll machine, to correct for varying amounts of roll deflection under varying operating loads. The mechanism includes a pair of biased levers which are pivoted on a frame diametrically across from one another against a bearing box on a calender roll. The roll has a mechanism at each end thereof. The levers are biased by incrementally movable pistons which when actuated, swing the respective ends of the calender roll in an arc about its midpoint to effectuate the controlled skewing of its axis with respect to the axis of a calender roll thereadjacent.Type: GrantFiled: January 19, 1981Date of Patent: September 14, 1982Assignee: USM CorporationInventor: Kendrick J. Gooch
