Such welding is conducted by vibrating two fiber reinforced thermoplastic parts under pressure along their common interface to generate frictional heat to melt and fuse their surfaces together. Fibers from at least one surface penetrate both into the weld and into the other surface. As a result, the welded, fiber reinforced thermoplastic surfaces have increased tensile strength than heretofore achievable. Vibration welds of reinforced thermoplastic surfaces according to this invention achieve a maximum tensile strength as high as about 120% of a weld formed by the unreinforced surfaces of corresponding thermoplastic materials.Type: GrantFiled: November 1, 1996Date of Patent: February 23, 1999Assignee: AlliedSignal Inc.Inventors: Valeriy Kagan, Caroline Bednarczyk, Siu-Ching Lui, Gregory R.

Patent number: 5871830Abstract: A fibrous product is produced by providing a collection of fibrous material, and encapsulating the fibrous material by covering the fibrous material with a film to form an encapsulated blanket of the fibrous material. The encapsulated blanket is then needled to cause entanglement of the fibrous material, thereby producing a needled, encapsulated fibrous product.Type: GrantFiled: February 29, 1996Date of Patent: February 16, 1999Assignee: Owens Corning Fiberglas Technology, Inc.Inventor: William S. Miller

Patent number: 5869162Abstract: Net which, in the unfolded state, has the form of a central part provided at the petrify with a number of flaps. Nets of this type are used to fix articles on pallets. The flaps in particular are subject to substantial loads and will frequently be damaged. So as to avoid the need to carry out extensive repair work on the net structure, it is proposed, according to the invention, to construct the net from various component nets. The production of the nets can likewise be facilitated in this way.Type: GrantFiled: February 19, 1997Date of Patent: February 9, 1999Inventor: Josephus Michael Anthonius Traa

Patent number: 5865002Abstract: The invention relates to a joint arrangement in connection with the manufacture of a wood element blank, especially a wood board blank or a wood beam blank, in which arrangement the wood element blank is arranged to be formed of several blank battens (1-4) that are arranged to be interconnected with an adhesive, whereupon each blank batten (1-4) is formed to have at least partly substantially triangular cross section, so that it may rest on at least four adjacent blank battens, and that the apex of the triangular part of each blank batten (1-4) remains inside the wood element blank. In order to improve the yield and the strength properties, each blank batten (1-4) is formed with substantially radial cleavings, so that the pith of the wood remains at the apex of the triangular part of the blank batten.Type: GrantFiled: June 16, 1997Date of Patent: February 2, 1999Inventors: Eero Tapojarvi, Sanna Tapojarvi, Minna Tapojarvi

Patent number: 5853857Abstract: The present invention provides a windshield frame utilizing composite technology. More particularly, the windshield frame preferably comprises a fiber reinforced plastic molded upper frame section bonded with a structural grade adhesive to a fiber reinforced plastic molded lower frame section. According to the invention, steel reinforcements and tapping plates are bonded on or molded into the frame sections to stabilize the structure and provide hardware attachment points. Continuous carbon fibers may also be molded in the frame sections in critical high stress areas. The strength of the bonding between the frame sections is enhanced by a tongue and groove geometry along the interface. In addition, dowel pins and bushings are used to mechanically tie the frame sections together near body side attachment points.Type: GrantFiled: February 20, 1997Date of Patent: December 29, 1998Assignees: The Budd Company, Chrysler CorporationInventors: Mohammed Mahmood, Michael M. Shinedling, Saad M. Abouzahr, Stuart A. Ehrhardt, Dennis G. Karolski

Patent number: 5843552Abstract: A sealing tape for sealing linear seams formed by adjacent substrate sheets comprises two laterally spaced linear strips interconnected with an intervening linear center strip. The center strip comprises a soft, pliable, adhesive sealant material adapted to flow into the substrate seam upon application of heat and pressure to the sealing tape. The laterally spaced side strips are dimensionally stable and comprised of a tacky elastomeric compound adapted to adhere to the substrate under applied heat and pressure.Type: GrantFiled: June 1, 1993Date of Patent: December 1, 1998Assignee: Bridgestone/Firestone, Inc.Inventor: H. Alan Karrfalt

Patent number: 5840141Abstract: A splice having (a) a support comprising a polymeric film having a major surface; and (b) a fiber reinforcement comprising a plurality of monofilaments where the monofilaments have longitudinal axes extending in a parallel direction, one to another, across the major surface, and the monofilaments are bonded to the major surface of the support by a fiber adhesive, where the fiber adhesive is a moisture-cured polyurethane adhesive. The invention also relates to methods and products thereof for using the splice to form spliced flexible abrasive articles, including endless belt forms.Type: GrantFiled: July 12, 1996Date of Patent: November 24, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventor: Gerald E. Korbel

Patent number: 5840378Abstract: An endless woven fabric for condensing paper material and a method for forming such an endless fabric which removes ink and other extraneous substances from the aqueous solution of reclaimed paper material. On the endless fabric formed by weaving plastic monofilaments, an antiflexing part, 30-50 mm in width, is provided on at least one end of the selvage in the direction of width by causing thermoplastic resin to fill not less than 85% of an empty space in the endless woven fabric. Further, a guide ridge of thermoplastic resin is formed by causing thermoplastic resin to fill an empty space in the end parts on the running surface of the endless fabric, and is welded with the antiflexing part integrally. Platelike reinforcing strips are formed in a length nearly equal to the width of the endless fabric. The strips are extended between the opposite ends of the endless fabric by causing thermoplastic resin of the strips to fill not less than 85% of an empty space in the endless fabric.Type: GrantFiled: December 12, 1996Date of Patent: November 24, 1998Assignee: Nippon Filcon Co., Ltd.Inventors: Hiroyuki Nagura, Takehito Kuji

Patent number: 5834083Abstract: Used tires are sorted on-site to separate those which are still good from those that are scrap. At the site, the sidewalls are separated from each scrap tire and the remaining tire portion is slit transversely and laid flat, stacked one atop the other. The stack is transported by vehicle from the site to a central processing facility that shears the tire portions to a uniform width and thickness. The uniformly dimensioned tire portions are then connected into strips by male/female dovetail cuts. Two strips are bonded together at their flat inner tire sides to form a two-ply tread strip. The two-ply tread strips are then used in construction, building component manufacture, fencing or landscaping; the two-ply treads are more flexible then lumber. The sidewalls are used as landfill or grounds cover in landscaping.Type: GrantFiled: February 10, 1997Date of Patent: November 10, 1998Inventor: Alfred J. Pignataro, Jr.
