Patent number: 7393193Abstract: A system is capable of making a metallic product with robust mechanical and electrical properties. The system includes a pressing stage configured to compress powder (e.g., MMC material) to form a green compact from the powder, a sintering stage configured to sinter the green compact to form a sintered structure from the green compact, and a consolidation stage configured to apply electric current to the sintered structure to form the metallic product from the sintered structure. The electric current is in the form of high density, short electric AC or DC pulses and results in consolidation of the sintered structure at grain boundaries to correct defects in the boundaries (e.g., areas of high electrical resistance) without melting the bulk metal to produce the metallic product. Such a system alleviates the need for coining process, which could fracture bonds and thus weaken the structure, following the sintering process.Type: GrantFiled: December 22, 2004Date of Patent: July 1, 2008Assignee: EMC CorporationInventors: Nader G.

Patent number: 5580412Abstract: A method and an apparatus for the production of a three-dimensional textile (3), wherein the textile (3) is formed from two sheets of textile (5, 6) placed face to face and connected together by a plurality of threads (10), impregnated with resin and inserted between two layers (16, 17) so as to form a layered structure (1). This layered structure (1) is inserted between two dies (25, 26) of a heated press which is subsequently closed to allow the resin impregnating the structure to distribute itself uniformly. The layers (16, 17) are then attached by vacuum to the faces of the dies (25, 26) which are then opened through a first controlled distance within the limit of the elastic recovery of the three-dimensional textile (3). The outermost layers of the structure (1) are then polymerized by heating the dies (24, 26) while the resin impregnating the threads (10) remains in a plastic state.Type: GrantFiled: July 27, 1995Date of Patent: December 3, 1996Assignee: Metalleido S.R.L.Inventor: Marco Fantino

Patent number: 5401156Abstract: An automatic filling machine for forming, sizing, transferring and inserting a food product portion into a container. The machine has forming chambers that are expandable to facilitate receiving a food product in bulk and are contractible to define a column having a cross section mating that of a container to be filled. The chamber is expanded to receive a quantity of a food product that is to be inserted into a container. The chamber is contracted to form the food product received therein into a column as defined by the contracted chamber. An upper plunger is provided to force and compress the formed food product column into a sizing apparatus. A pressure switch controls the compressive force applied to the food product column to provide consistency between sized portions of the food product.Type: GrantFiled: December 8, 1993Date of Patent: March 28, 1995Assignee: Carruthers Equipment Co.Inventor: Paul S.

Patent number: 5395227Abstract: An adjustable powder flow gate for a rotary pellet press has a movable gate wherein one dimensional motion of the gate across an opening in a powder flow feed frame on the rotating turret of the press is effected with a rotatable shaft having a screw connection to a member attached to the gate. The shaft is maintained in a selected rotational position with a bias member that is movable between an engaged and a disengaged position. The bias member is adapted to engage a selected detent on a member attached to the shaft having several circumferentially spaced detents when the bias member is in the engaged position. The shaft can freely rotate when the bias member is in the disengaged position. An operator can easily adjust the size of the opening by first disengaging the bias member from the selected detent, turning the shaft to move the gate to the desired position, and then engaging the bias member into a newly selected detent.Type: GrantFiled: August 20, 1993Date of Patent: March 7, 1995Assignee: Westinghouse Electric CorporationInventors: Thomas B.

Patent number: 5382150Abstract: A method and apparatus of molding articles from composite materials are dlosed in which a stack of prepregs are placed on a first forming surface of a former, which forming surface has a surface configuration matching that of one side of the composite article, placing a semi-rigid molding shelf onto the former such that a second forming surface of the molding shell, which matches the surface configuration of an opposite side of the composite article, bears against the stack of prepregs and urging the molding shell towards the former, thereby compressing the plies of prepregs by drawing a vacuum between an impermeable membrane covering the molding shell and the former. The assembly of the former, the molding shell, the stack of prepregs and the impermeable membrane are placed in an autoclave such that it may be heated while the vacuum is drawn between the membrane and the former to compress the stack of plies of prepregs.Type: GrantFiled: March 16, 1994Date of Patent: January 17, 1995Assignee: Societe nationale D'Etude et de Construction de Moteurs D'AviationInventor: Philippe Henrio

Patent number: 5328345Abstract: An expansion molding apparatus for forming molded articles having consistently or partially thin-walls by expanding expandable thermoplastic resin beads in a cavity formed between molds with the application of heat. The apparatus has a moving device, for example, a cylinder which moles the molds in one orthogonal direction relative to a closing direction of the molds when filling the cavity with the expandable thermoplastic resin beads. After filling the resin beads in the cavity by moving at least one of the molds in at least one direction orthogonal to the closing direction so that a distance in a circumference section of the cavity becomes greater, the mold is moved back to the original position and the application of heat is performed to obtain molded articles.Type: GrantFiled: December 17, 1992Date of Patent: July 12, 1994Assignee: Sekisui Kaseihin Kogyo Kabushiki KaishaInventors: Ken Yamamoto, Masaru Harao, Hideo Takamatsu

Patent number: 5275056Abstract: A gyratory shear material compacting device in which a material sample is placed within a cylindrical mold having a wobble plate. The material sample is compressed by a piston while the mold is simultaneously gyrated. Gyration is achieved by tilting the mold and holding the wobble plate within rollers which revolve around the mold, controlling the selected angle of tilt while imparting oscillatory gyration. The selected angle of tilt of the mold may be precisely controlled at all times, preventing the mold from riding up on the sample, or from coming into contact with the base of the device. The mold is free to advance rotationally. The device is capable of measuring and recording the height of the sample, angle of gyration, and moment of gyration.Type: GrantFiled: October 20, 1992Date of Patent: January 4, 1994Assignee: Rainhart Co.Inventors: Edward R. Hamilton, Raymond D. Alexander, Lawrence E. Hart

Patent number: 5088399Abstract: Pressing apparatus comprising a die made up of a number of segments defining a cavity in which metal swarf is compacted to form a billet. The die segments are held together by one or more sleeves housed in a housing which is mounted on a pedestal which pivots between a first position in which the cavity is aligned with one or more rams which are advanced into the cavity to compact the swarf, and a second position in which the cavity is aligned with gripping devices which grip the ends of the die segments and separate them radially to release the billet after a jacking device mounted on the housing is actuated to move the sleeves in the axial direction and release the die segments. One of the gripping devices may comprise a cylindrical bore through which an empty tube can be fed into the cavity and the other gripping device may similarly comprise a cylindrical bore through which the billet can be fed after it has been ejected from the die cavity.Type: GrantFiled: September 21, 1990Date of Patent: February 18, 1992Assignee: Camborne Industries PLCInventors: Antonino G.
