Patent number: 10538018Abstract: A method includes processing multiple macromolecular staples to successively produce a macromolecular sheet body, multiple silks and multiple sheet particles. The macromolecular sheet body contains multiple district camouflages and is processed by edge cutting to form multiple color strips. The color strips, the silks and the sheet particles are processed and attached to the surface of the macromolecular sheet body, so that the surface of the macromolecular sheet body forms the district camouflages, the thread camouflages and the spot camouflages. Finally, the macromolecular sheet body is vulcanized or solidified in a foam molding zone, to form an elastic mat with a mixed color type.Type: GrantFiled: July 21, 2017Date of Patent: January 21, 2020Assignee: Simple Green Co., Ltd.Inventors: Chen-I Kao, Shang-Chieh Kao, Shu-Chen Huang, Hsueh-Fang Kao, Yung-Ping Lai

Patent number: 5750444Abstract: A breathable laminate comprises at least two porous webs laminated together with a porous adhesive matrix, preferably a random fibrous adhesive pattern having a coat weight of between 1.5 and 12 grams per square meter. The two or more porous webs comprise woven or non-woven materials and the resulting breathable fabric or laminate has good hand and flexibility. Breathable fabric is adhered to foam by such random fibrous adhesive patterns of similar coat weights. Coating widths of up to 80 inches or more are produced in a slot die fed by a selected plurality of recessed lands within the die, with motors and pumps controlled to maintain consistent, uniform coat weights regardless of coat widths and substrate speeds selected. Single ply coated webs, apparatus and methods are disclosed.Type: GrantFiled: October 4, 1993Date of Patent: May 12, 1998Assignee: Nordson CorporationInventors: Curt Jarrell, Manfred Kubo, Hans-Jurgen Meissner, Gustav Rieckmann, Jurgen Benecke

Patent number: 5584952Abstract: A method and apparatus for making drip irrigation lines, by forming two (or more) tubes in side-by-side relation joined together at a juncture including a plurality of preformed members bonded to and within the juncture at spaced locations along the longitudinal axes of the preformed members and of the juncture. Each of the preformed members includes a pair of flow-reducing, groove formations, one on each side of the longitudinal axis of the preformed member. The juncture is slit along the longitudinal axes of the preformed members to thereby form two (or more) drip irrigation lines each integrally formed with a section of the plurality of preformed members, each section having one of the groove formations serving as a flow-reducer element in the respective line.Type: GrantFiled: August 15, 1994Date of Patent: December 17, 1996Assignee: Hydromatic Ltd.Inventors: Zvi Rubenstein, Valish Malkin

Patent number: 5387303Abstract: An apparatus for forming a rubber sheet having cords embedded therein includes a grooved roll formed in its circumference with a plurality of circumferential grooves for arranging cords with equal pitches, and a pressure-joining roll arranged spaced from the grooved roll for pressure-joining a first rubber sheet with the cords arranged with the equal pitches in a first pressure-joining position between the grooved roll and the pressure-joining roll. The apparatus further includes a groove forming roll for forming a plurality of longitudinal grooves in one surface of a second rubber sheet, and a forming roll arranged spaced from the pressure-joining roll to form a second pressure-joining position between the forming roll and the pressure-joining roll.Type: GrantFiled: June 29, 1993Date of Patent: February 7, 1995Assignee: Bridgestone CorporationInventor: Toshio Azuma

Patent number: 5298097Abstract: An apparatus and method provides for thermally bonding a textile web while supporting the web continuously from the lay down point until the web is thermally bonded. The apparatus includes a heated transfer roll adjacent an endless moving belt. The transfer roll is located outside the belt loop on the opposite side of the belt from a guide roll. The belt passes around a first portion of the transfer roll with the web sandwiched between the belt and transfer roll. The heated transfer roll heats the web and the web is transferred to the transfer roll. The web is then directed through a nip formed by a calender roll positioned adjacent a second portion of the transfer roll for thermally bonding the web.Type: GrantFiled: March 31, 1992Date of Patent: March 29, 1994Assignee: Neuberger S.p.A.Inventor: Roberto Zanferrari

Patent number: 5192559Abstract: Systems for and methods of generating three-dimensional objects from a medium capable of selective physical transformation upon exposure to synergistic stimulation, whereby sheets of medium corresponding to cross-sectional layers of the three-dimensional object are dispensed from a source, the dispensed sheets then being selectively exposed to synergistic stimulation thereby forming a layer of the three-dimensional object, the areas not exposed to synergistic stimulation being removed, and whereby successive sheets corresponding to successive cross-sectional layers are dispensed and selectively exposed to synergistic stimulation and integrated together with preceding layers to provide substantially a layer by layer buildup of the three-dimensional object, thereby forming the three-dimensional object.Type: GrantFiled: December 3, 1991Date of Patent: March 9, 1993Assignee: 3D Systems, Inc.Inventors: Charles W. Hull, Paul F. Jacobs, Kris A. Schmidt, Dennis R. Smalley, Wayne A. Vinson

Patent number: 5183598Abstract: Process for obtaining three-dimensional objects, according to which process a sheet (2A, 2B, 2C) is prepared, which sheet is composed of a material, the solubility of which varies when it is subjected to a specific radiation, and of fibers or of a screen for reinforcement, the sheet having a sufficient rigidity to be handled and being capable of adhering on a similar sheet. The sheet is subjected to said radiation (18) in a defined zone, and then a new sheet is fixed onto it and the passing of radiation is recommenced, and then the stack is subjected to a selective dissolving which causes the desired object (31) to appear.Type: GrantFiled: March 4, 1991Date of Patent: February 2, 1993Assignee: Dassault AviationInventors: Jean-Louis Helle, Jean-Claude Andre, Philippe Schaeffer

Patent number: 5174845Abstract: The insulating coating for an object such as a rocket motor casing is formed by wrapping a strip of insulating material upon the surface of a rotating mandrel. By means of this invention, it is possible to wrap a strip of malleable material such as rubber from an extruder onto a complex shape while exercising precise thickness control, thereby eliminating the need for machining the outer surface. The strip is run through a forming mill of unique construction which shapes the strip during the wrapping process to conform most precisely with the topography of the mandrel. The mill automatically varies both the taper and the width of the strip. The final wrapped product has a smooth outer surface that requires minimal finishing.Type: GrantFiled: July 18, 1991Date of Patent: December 29, 1992Assignee: Thiokol CorporationInventor: Phillip C.

Patent number: 5122212Abstract: An improved process and means are disclosed for continuously forming tiles that are embossed in register with a printed design. In this process a base layer is formed on a continuously moving support surface and moved by the surface through printing, laminating and embossing stages wherein a printed design is applied to the base layer, a wear coat is laminated over the design, and the design is embossed. In accordance with the invention, the base layer is adhered to the support surface prior to transfer of the printed design thereto.Type: GrantFiled: October 27, 1989Date of Patent: June 16, 1992Assignee: American Biltrite, Inc.Inventors: Donald C.
