Patent number: 12201118Abstract: An apparatus and method for separating meat from bone. Meat-laden bones are fed to a compression screw rotating within a barrel. The compression screw and the barrel cooperate to progressively compress the meat-laden bones to force the meat-laden bones radially outward against an inner wall of the barrel as the meat-laden bones move axially along the compression screw. At least a portion of the meat is separated from the meat-laden bones by forcing the meat through apertures in the barrel while inhibiting the meat-laden bones from co-rotating along within the barrel with the compression screw. In one embodiment, inhibiting the meat-laden bones from co-rotating within the barrel along with the compression screw is accomplished by cooperation of guide channels extending axially along an inner surface of the barrel with curved fillets extending between a root of the compression screw and screw flights of the compression screw.Type: GrantFiled: January 16, 2024Date of Patent: January 21, 2025Assignee: POSS DESIGN LIMITEDInventors: Kenneth Benjamin Gulak, Neil Metcalfe

Patent number: 5641741Abstract: A process for producing granules of anionic surfactant, preferably PAS by in situ neutralisation of a precursor acid to form the surfactant, heating the surfactant to a temperature in excess of 130.degree. C. and subsequently cooling the to provide surfactant granules is disclosed. Detergent compositions containing such granules are also disclosed.Type: GrantFiled: August 24, 1995Date of Patent: June 24, 1997Assignee: Lever Brothers Company, Division of Conopco, Inc.Inventors: William Derek Emery, Kenneth Metcalfe, Peter James Tollington

Patent number: 4193794Abstract: A method of producing a liquid developer for electrostatic images by subjecting a low density polymer to a solvent of relatively smaller molecular size so that the solvent activates the polymer chains to form a modifying carrier liquid, and then applying the modifying carrier liquid to particles of solid toner material so that by dilatant action the molecular bonds of the particles are broken to produce a fine developer held in a lattice structure.Type: GrantFiled: April 30, 1976Date of Patent: March 18, 1980Assignee: The Commonwealth of AustraliaInventors: Kenneth A. Metcalfe, Alwin S. Clements, Clive W. Wilson

Patent number: 4172905Abstract: A method of transferring images from one surface to another, which, instead of using a steady field uses a corona to build up a charge on a roller which transfers the charge to the surface where transfer is required. The device comprises a pair of rollers which are urged toward each other, one of the rollers having an insulator surface, the other roller forming an electrode, the charge being applied to the insulator surface on the one roller by means of a corona generating device spaced from the insulator surface and remote from the electrode roller.Type: GrantFiled: January 18, 1974Date of Patent: October 30, 1979Assignee: The Commonwealth of AustraliaInventors: Kenneth A. Metcalfe, Alwin S. Clements, Brian J. Horrocks

Patent number: 4134762Abstract: The method of coating a pervious fibre sheet with a photoconductor in which the photoconductor, a resin and a solvent for the resin are each selected and combined to have different penetrating power when applied to the pervious sheet whereby the photoconductor has a minimum penetration, the resin has a greater penetration and the solvent has the greater penetration, the components being selected to have an increasing dielectric constant inwards from the surface of the sheet, the resin being hydrophobic and capable of wetting both the photoconductor and the fibre.Type: GrantFiled: June 14, 1977Date of Patent: January 16, 1979Assignee: The Commonwealth of AustraliaInventors: Kenneth A. Metcalfe, Alwyn S. Clements

Patent number: 4049446Abstract: A method of developing electrostatic images in which a liquid developer is maintained in quiescent condition in contact with the base material carrying the electrostatic image and wherein the developer contains in separate coexistence within an insulating carrier liquid toner particles of relatively low dielectric constant and movement-inducing particles having a high dielectric constant. The presence of both sets of particles results in agitation in the liquid due to particle movement in a field by charge exchange between the high dielectric particles and the other particles to produce random agitation of the particles in the liquid and thereby high mobility of the toner particles during developing.Type: GrantFiled: February 9, 1976Date of Patent: September 20, 1977Inventors: Kenneth A. Metcalfe, Clive Westgarth Wilson, Denton Field

Patent number: 3992311Abstract: A method for making an electrophotographic developer having developer particles suspended in an insulating carrier liquid comprising reactively producing the developer particles by placing into the carrier liquid at least two substances which are both soluble in the carrier liquid and are insulators relative to the carrier liquid and when in a dissolved state in the carrier liquid precipitate in the carrier liquid to form the developer particles. The developer particles are maintained in the carrier liquid so as to be shielded against oxidation until used as a developer.Type: GrantFiled: July 24, 1975Date of Patent: November 16, 1976Inventors: Kenneth A. Metcalfe, Alwin S. Clements
