Patent number: 5484641Abstract: A method of fixing plastic reinforcing pins into non-woven filamentary material includes the steps of: (a) providing an elongated web of randomly-aligned synthetic fibers, (b) creating a repeating pattern of holes through the by a hole-punching mechanism having a plurality of heated punch heads maintained at a temperature above the melting point of the synthetic fibers, (c) conveying the web from the punching mechanism over a supporting belt such that the belt provides a closed bottom for each hole, (d) injecting a quick-setting liquid polymer into the holes with an injector mechanism having a plurality of liquid injector nozzles arranged in an identical pattern as the pattern of punch heads and operated in coordinated sequence with the punching mechanism, such that an injector nozzle is inserted into a corresponding hole, and (e) allowing the severed ends of the fibers to imbed into the liquid polymer before it sets.Type: GrantFiled: November 1, 1993Date of Patent: January 16, 1996Inventor: Martin J. Rotter

Patent number: 5470424Abstract: Disclosed are a number of processes for forming a liquid-impermeable sheet having a fibrous cloth-like surface. In one embodiment the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces; and subjecting the sheet to pressure and a z-gradient temperature differential sufficient to melt the fibers of the first surface and form the melt into a liquid impermeable skin without significantly altering the fibers of the second surface.Type: GrantFiled: November 30, 1993Date of Patent: November 28, 1995Assignee: Kimberly-Clark CorporationInventors: Robert L. Isaac, Bernard Cohen, Lee K. Jameson

Patent number: 5458717Abstract: A method of shearing a thin metal sheet having a thickness of approximately 0.1 mm or less so as to be separated into a product and scrap by a pair of dies. A chamfer or a round having a size of approximately from 5 to 10 times greater than the thickness of the thin metal sheet is arranged at the lip of a first die which presses one portion of the thin metal sheet which is to be scrap. A chamfer or a round is not substantially arranged at the lip of a second die which presses the other portion of the thin metal sheet which is to be a product. A backing material and the thin metal sheet are overlapped so as to be a laminate. The backing material has a thickness of approximately 2 times or more greater than that of the thin metal sheet and is formed of a flexible material having a very small elongation and is soft enough not to substantially prevent the thin metal sheet from being sheared, such as, for example, paper.Type: GrantFiled: December 22, 1993Date of Patent: October 17, 1995Assignee: Nippondenso Co., Ltd.Inventor: Mikiya Kurita

Patent number: 5453146Abstract: A needle bar is made from a support member and a carrier. The needle bar can be made with a plurality of needle grooves. The bar is made by adhering the support member to the carrier. Then the support member is divided into a plurality of individual segments of predetermined length, after the support member is adhered to the carrier. Adjacent ones of the individual segments (a) can be spaced to form a gap narrower in width than the needle grooves, and (b) can have opposing edges shaped to form a concavity having a width equivalent to the needle grooves.Type: GrantFiled: January 31, 1994Date of Patent: September 26, 1995Assignee: Karl Mayer Textilmaschinenfabrik GmbHInventor: Rainer Kemper

Patent number: 5452867Abstract: An aircraft structure, such as a wing, is made of fiber composite material and includes a shell structural component also made of fiber composite material. The structural component has at least one access opening closeable by a cover. The shell structural component has a first area containing the access opening closeable by the cover. In the longitudinal direction of the wing the first area is predominantly flexible while a second area surrounding the first area is predominantly stiff, whereby these areas take up different longitudinally effective forces, relative to the length of the wing. Both areas are capable of transferring shear forces in the same manner.Type: GrantFiled: October 8, 1993Date of Patent: September 26, 1995Assignee: Deutsche Aerospace Airbus GmbHInventors: Gero Grunwald, Michael Hauschildt

Patent number: 5439542Abstract: A composite article useful as a material of construction made of a plurality of substantially aligned, individual pieces of corrugated cardboard cut from scrap corrugated boxes or sheets. The corrugated pieces lie in a shingle-like configuration, a bridge-like configuration, or a combination thereof and form multiple, generally planar layers of individual corrugated cardboard pieces having a length only a fraction of the full length of the article. The material of construction is particularly useful in making shipping pallets to replace wood pallets currently in use.Type: GrantFiled: July 26, 1994Date of Patent: August 8, 1995Inventor: Henry L. Liebel

Patent number: 5437758Abstract: A "green" sheet manufacturing method and apparatus contemplates perforating the "green" sheet with through-holes as it is calendared, rolled or extruded by rollers. To this end, the rollers are each machined with punches of a length one-half the thickness of the "green" sheet and that mate with punches on the other. Any flash or diaphragm obtaining in the through-holes are removed by subsequently exposing the "green" sheet to new mechanisms providing fluid pressure or vibration, or spiking. The bosses or punches may be supplemented with enlargements and other bosses providing for pads and counterholes and grooves in the "green" sheet. The through-holes may be shaped to have a smaller diameter interiorly than at the outer edges to lock in place solder or other conductive media squeegeed into them. The locking action may be enhanced by slightly off-setting bosses or mating punches to produce through-holes whose top and bottom halves are slightly off-set.Type: GrantFiled: May 9, 1990Date of Patent: August 1, 1995Assignee: Joseph B. TaphornInventor: Thomas J. Walsh, Jr.

Patent number: 5430901Abstract: A therapeutic mattress overlay for supporting a recumbent human body so as to redistribute body weight away from prominent areas of the human body and also to support selected anatomical body portions, e.g., the lower extremities, of the recumbent human body has a substantially planer resilient member having top and bottom surfaces and first and second edges. Reinforcements extend from proximate the first edge to proximate the second edge of the planer resilient mender such that a patient may be rotated by grasping the reinforcements proximate the first edge of the resilient member and lifting the first edge thereof so as to cause the patient to roll toward the second edge thereof. The reinforcements prevent damage to the resilient member during lifting of the first edge. The pad is formed to have at least one area of less resistance thereon which corresponds to protruding portion(s) of a human body.Type: GrantFiled: June 10, 1993Date of Patent: July 11, 1995Inventor: David L. Farley

Patent number: 5429700Abstract: A sealed aperture is formed in a laminated assembly by prepunching a central sheet such as a paper art print to form a first aperture and then laminating the art print between two sheets of laminating film to form a laminated assembly in which the two films are fused together in the aperture to form a single film in the form of a disc. A second aperture is then punched through the disc having a smaller diameter than the film aperture such that a sealed border remains between the second aperture and the first aperture.Type: GrantFiled: March 15, 1994Date of Patent: July 4, 1995Assignee: The Splash Art CompanyInventor: Robert L.

Patent number: 5427416Abstract: A business form 10 includes a planar carrier 12 having a card 14 demarcated therein and a window 18 defined in the carrier 12 adjacent the card 14. A planar element 20 of a synthetic plastics material is laminated to the carrier 12 in register with the card 14 and the window 18 so that a part 20.1 of the element 20 is arranged within the window 18. A coating of adhesive material is carried by at least that part 20.1 of the element 20 in the window 18 so that, upon removal of the card 14 and that part 20.1 of the element 20 in the window 18, said part 20.1 of the element 20 can be folded over onto the card 14 and adhesively secured to the card 14 to form an arrangement where both surfaces of the card 14 are covered by the plastics material.Type: GrantFiled: October 4, 1993Date of Patent: June 27, 1995Assignee: Lithosaver Systems LimitedInventor: Neil W.
