Publication number: 20090139661Abstract: A composite pipe has a metal conduit sandwiched between inner and outer conduits of PVC/CPVC, each of which are adhesively secured to the interlaying metal conduit with a dried, solvent-free thin layer of a thermosetting bilayer adhesive which provides a bond with the metal, which bond fails in cohesive failure. Narrowly defined limits on the thickness of each conduit are found to provide a bendable composite pipe with an aluminum interlayer; and to provide a rigid non-bendable composite pipe with a steel interlayer. Making the composite pipe which meets required ASTM and NSF test considerations requires unexpectedly critical process steps. A process for making the pipe is disclosed, as are PVC/CPVC fittings which allow lengths of pipe to be solvent-cemented in them so as to seal the terminal ends of the pipe against infusion of fluid under pressure in the pipe, thus preventing delaminaton.Type: ApplicationFiled: November 26, 2008Publication date: June 4, 2009Applicant: LUBRIZOL ADVANCED MATERIALS, INC.Inventors: Robert M.

Patent number: 7111657Abstract: In the resin film forming method for extruding a fused resin from an extruder die to form a resin film, the second resin forming both ends in width direction of the resin film uses a resin greater in extension viscosity than the first resin forming the center in width direction of the resin film.

Patent number: 6811632Abstract: A method and apparatus for welding thermoplastic materials with a stir welding system using a rotating element pin or element with a geometry to induce frictional energy from the rotating element. A floating constraining surface that has a motion independent of the rotation the pin (preferably stationary) is used to constrain ejection of material from the zone where the weld is being formed. Molten material is retained in the weld region, avoiding weakness and voids at the weld joint. Optionally a system for introducing thermal energy into the weld zone in addition to the frictional energy is used. The system for introducing the thermal energy may be in association with the constraining shoe and/or the rotating tool, or a system independent of these.Type: GrantFiled: April 28, 2003Date of Patent: November 2, 2004Assignee: Brigham Young UniversityInventors: Tracy Wendell Nelson, Carl David Sorenson, Clark Joseph Johns

Patent number: 6805771Abstract: This invention relates to a lamination apparatus and in particular to a dual belt driven, continuous pressure lamination apparatus that utilizes pressure, heat and cooling to bond at least two substrates (plies) with an adhesive between the layers of the substrates. The pressure laminator of the present invention has been specifically designed to permit the permanent joining of at least two fabric substrates with an adhesive between the fabric substrates, with little or no shrinkage occurring during the lamination process. The resulting non-woven fabric advantageously has the appearance of a woven fabric, but has superior strength characteristics there over. The pressure laminator of the present invention can have other uses, for example, printed circuit board substrate manufacture, and the like, as will be appreciated by those having ordinary skill in this art.Type: GrantFiled: July 1, 2002Date of Patent: October 19, 2004Assignee: Hunter Douglas Industries B.V.Inventors: Wendell B.

Publication number: 20040163769Abstract: In the resin film forming method for extruding a fused resin from an extruder die to form a resin film, the second resin forming both ends in width direction of the resin film uses a resin greater in extension viscosity than the first resin forming the center in width direction of the resin film. Thereby, even if production conditions such as resin condition and operating conditions change, faults such as neck-in and its resultant thickening at both ends of the resin film can be suppressed. In the production of a laminate by nipping a support and a resin film of a thermoplastic resin by means of a nip roller and a cooling roller while coating the resin film onto the surface of the support, the accompanying air following the rotation of the cooling roller to the nip point is shut off by blowing a gas permeable through the resin film from a gas jet nozzle toward the surface of the cooling roller.Type: ApplicationFiled: March 2, 2004Publication date: August 26, 2004Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Tadahiro Kegasawa, Ryuichi Katsumoto, Masanori Takase, Hidetoshi Okamura

Patent number: 6780264Abstract: A method for welding synthetic resin members includes the steps of detecting a temperature of a high frequency electrode or an ultrasonic horn (or an anvil) by a temperature detector, cooling the high frequency electrode or the ultrasonic horn (or the anvil) by cooling means when the temperature detected by the temperature detector during a high frequency or ultrasonic vibration exceeds a preset temperature range, thereby reducing the temperature rapidly down to the preset temperature range, and stopping an operation of the cooling means when the temperature of the high frequency electrode or the ultrasonic horn (or the anvil) is reduced to the preset temperature range.Type: GrantFiled: November 20, 2002Date of Patent: August 24, 2004Assignee: YKK CorporationInventors: Yoshifumi Nakata, Osamu Igarashi, Michio Ito

Patent number: 6739367Abstract: The invention relates to a plastic film heat seal apparatus which comprises a heat seal bar covered with at least one low adhesive sheet. The heat seal bar is pressed against superposed layers of plastic film so that the layers of plastic film can be heat sealed with each other by the heat seal bar to have a heat sealed portion whenever the layers of plastic film are intermittently fed in a direction and temporarily stopped. The low adhesive sheet is interposed between the heat seal bar and the layers of plastic film for protection of the layers of plastic film when the heat seal bar is pressed against the layers of plastic film. The heat seal bar is then retreated and spaced from the layers of plastic film to permit the layers of plastic film to be fed again after being heat sealed. The heat sealed portion includes upstream and downstream edges in the plastic film feeding direction.Type: GrantFiled: October 30, 2002Date of Patent: May 25, 2004Assignee: Totani CorporationInventor: Mikio Totani

Patent number: 6706137Abstract: A tool and method for bonding two carpet pieces by use of a vacuum which forces air to move upwardly through the carpet and to cool the hot glue adhesive. The invention goes beyond providing a uniquely strong bond by leveling the carpets on both sides of the bond seam. Thus it also has the ability to bond a thin side of carpet with a thicker side of carpet because of leveling of the carpet on both sides of the bond seam thus hiding the seam more perfectly (many times when a carpet manufacturer shears a carpet one side will be thicker than the other side). Alternately, thin carpets may be bonded without risk of having a weak bond. When several carpets are bonded together with multiple seams, the carpet may be stretched more than conventionally bonded carpets due to the great strength of bonds made in accordance with this invention. All species of the invention enjoy a substantial savings in time needed for seaming.Type: GrantFiled: May 14, 2002Date of Patent: March 16, 2004Inventor: Daniel Paul Bennett

Patent number: 6699354Abstract: The gluing together of flat materials between belt faces (21, 22), facing one another, of belt conveyors (15, 16) arranged over one another is effected usually with the application of heat and pressure. However there are pressure sensitive materials that with the gluing may only be impinged with a slight pressure. Here already the weight of the sagging belt face (21) of the upper belt conveyor may lead to an excessive pressure loading and a permanent deformation of the materials caused by way of this. The invention solves the mentioned problem in that the upper belt face (21) located above the materials to be glued is held up without contact, e.g., by means of suction nozzles or magnets. The sagging of the belt face (21) is alleviated by way of this and an undesirable high pressure loading of the materials to be glued is avoided. By way of the contactless holding-up of the belt face (21) the suction nozzles or magnets do not interfere.Type: GrantFiled: May 24, 2001Date of Patent: March 2, 2004Assignee: Schaetti AGInventors: Peter Schwenk, Wilfried Dreischmeier
