Patent number: 5176777Abstract: In a process for covering an object by means of at least one flexible piece, a fluidized bed of particles (8) is covered by a flexible cloth (10), the flexible covering piece (12) is placed above said cloth, the object (13, 14) is placed above said cloth, pressure is applied to said object, deforming the flexible sheet and immersing the object in the fluidized bed until a mating imprint is formed in the latter. The covering can be effected by gluing, in particular with a previously applied heat-activated adhesive in which case the fluidized bed is obtained by means of a current of hot air at a temperature above the activation temperature of the adhesive. The process is particularly suitable for assembling and mounting seat covers. Also described is a device for implementing the process.Type: GrantFiled: January 14, 1991Date of Patent: January 5, 1993Inventor: Christian Guilhem

Patent number: 5145548Abstract: A highly efficient manufacture of magnetic cards can be achieved by the arrangement of the present invention in simple and compact structure. The manufacturing apparatus including laminating and cutting devices can automatize every step required for manufacture, e.g., supply, transfer and positioning of material or discharge of a finished card. In other words, the manufacturing arrangement performs the total process automatically from pre-treatment to post-treatment with high efficiency.Type: GrantFiled: September 13, 1990Date of Patent: September 8, 1992Assignee: NATEC IncorporatedInventor: Ryoichi Yamamoto

Patent number: 4814080Abstract: A filtration device provided with two rigid surfaces and two or more pneumatic supports disposed therebetween; one pneumatic support is mounted on each of the rigid surfaces. Two or more flexible tubular filtration elements are disposed in one or more rows between the pneumatic supports; in each row, the flexible tubular filtration elements are in parallel alignment.Type: GrantFiled: December 10, 1986Date of Patent: March 21, 1989Inventor: Jean-Claude Sauvaget

Patent number: 4382833Abstract: An apparatus for laminating a solar cell structure includes upper and lower housing members and an intermediate member which includes a flexible membrane. The members form upper and lower sealed chambers which can be selectively evacuated. The solar cell structure is placed between the membrane and a parallel rib structure in the lower chamber. Heater elements and reflectors between the ribs are employed for radiating heat energy to the solar cell structure during the laminating process for melting a potting material therein, while both chambers are evacuated. Then air is admitted to the upper chamber to cause the membrane to compress the laminated structure against the parallel rib support means while the laminated structure cools.Type: GrantFiled: August 25, 1981Date of Patent: May 10, 1983Assignee: RCA CorporationInventors: Peter J. Coyle, Marvin S. Crouthamel

Patent number: 4273604Abstract: Apparatus for bonding heat bondable materials through the application of pressure and heat employs a diaphragm pressed by fluid pressure against the materials. The diaphragm comprises a web having a flexible heating element which is bonded to its non-material pressing side and has a configuration corresponding to the desired seam configuration. The web carries heat dissipating means to conduct heat away from the diaphragm and the materials in the seam configuration and heat directing means to conduct heat from the element to the seam area. Preferably the heating element, heat directing means and heat conducting means are formed from metallic foil bonded to both sides of the web and having portions etched away to provide electrically insulating channels separating one from another.Type: GrantFiled: September 6, 1979Date of Patent: June 16, 1981Inventor: Orin B. Johnston

Patent number: 4264404Abstract: Cellulosic paper sheets interleaved with sheets of a thermoplastic material having a glass transition point below about 100.degree. C. and a melting point of about 125.degree. C. or more provide a cushion for use in laminating operations. The thermoplastic sheets employed in the cushion have an individual thickness ranging from about 2 to 20 mils and a combined thickness of at least 5 mils. Such a cushion provides a long-term, reuseable cushion for laminating operations.Type: GrantFiled: November 21, 1979Date of Patent: April 28, 1981Assignee: Formica CorporationInventor: Harold C. Giesler

Patent number: 4251314Abstract: Apparatus for bonding heat bondable materials through the application of pressure and heat employs a diaphragm pressed by fluid pressure against the materials. The diaphragm comprises a web having a flexible heating element bonded to its non-material pressing side and has a configuration corresponding to the desired seam configuration. An improved heating element configuration is disclosed to reduce the forces tending to separate the element from the web as a result of their different coefficients of expansion and provision is made fo facilitate electrical connection to the heating element while reducing unwanted effects on the heat pattern.Type: GrantFiled: September 6, 1979Date of Patent: February 17, 1981Inventor: Orin B.

Patent number: 4217157Abstract: A method for fabricating a filament reinforced metal matrix composite comprises bonding a plurality of filaments to a perforated metal foil with a fugitive binder, overlaying the filaments with a second perforated metal foil to form a stack, positioning the stack in a vacuum die, heating the stack in a vacuum to cause vaporization of the binder and evacuation of the vapors through the perforations in the foils and hot pressing to consolidate the stack.Type: GrantFiled: November 20, 1978Date of Patent: August 12, 1980Assignee: United Technologies CorporationInventors: Leon Stoltze, Harry A. Nutter, Jr., Robert F. Wilson

Patent number: 3964958Abstract: A device for heat bonding thermoplastic materials. At least one pressure chamber having a diaphragm is spaced from a supporting surface with the diaphragm and supporting surface in opposing relation to each other. Materials to be bonded are positioned between the pressure chamber diaphragm and supporting surface and the pressure in the chamber is raised above ambient pressure causing a deflection of the diaphragm. The amount of diaphragm deflection increases with the distance from the pressure chamber side wall. Either the supporting surface or the pressure chamber, or both, is moved toward the other causing a contact between the deflected diaphragm, supporting surface and the materials to be bonded. As the relative movement continues, the contact area with the materials to be bonded increases thereby progressively expelling air trapped between the materials.Type: GrantFiled: August 22, 1974Date of Patent: June 22, 1976Inventor: Orin B. Johnston
