Patent number: 5914171Abstract: The invention relates to an edge protector, method and fitted article, and in particular to an edge protector for use on generally flat faced, panel-like products such as doors, worktops, table-tops and the like. There is disclosed an edge protector (10) having a base (14), two opposed sides (16), each side including a leg (20) and an arm (22), the legs and arms comprising corrugated paper joined to plain paper, characterised in that the arms (22) extend between the legs (20), and in that the plain paper on tan arm faces plain paper on the other arm and in that plain paper on a leg faces away from plain paper on the other leg. There is further disclosed such edge protector wherein the legs and arms are of paper having fluting on one face and include resilient biassing means (24) acting to urge parts of the respective sides towards each other. There is also disclosed a method for making such an edge protector and an edge protector fitted therewith.Type: GrantFiled: October 14, 1997Date of Patent: June 22, 1999Assignee: Aston Packaging, Ltd.Inventor: Timothy Corben Morley

Patent number: 5911950Abstract: A system to deliver gas/vapor from solid materials. Specifically, the delivery system for the use of gas or vapor released from a solid material, such as a non-aqueous/solid hydrogen peroxide complex. The system is comprised of a delivery system that is configured to receive a plurality of disks containing the solid material and provide these disks into an injector. The injector heats the disks to produce a gas or vapor that is then provided into a chamber. The sterilization process can be done by gas or vapor alone, or in combination with plasma or ultra violet radiation. In particular, a control system automatically induces the delivery system to provide the injector with a disk and then remove the disk once the injection sequence is complete.Type: GrantFiled: September 30, 1997Date of Patent: June 15, 1999Assignee: Johnson & Johnson Medical, Inc.Inventors: Xiaolan Chen, Paul Taylor Jacobs, Szu-Min Lin, Robert M. Spencer, Harold R. Williams

Patent number: 5900295Abstract: A fixing roller for an electrophotographic device has a cylindrical-shaped metallic base body, an insulation layer formed on an outer peripheral surface of the cylindrical-shaped metallic base body, and a resistance resin layer laminated on the insulation layer. The resistance resin layer is prepared using an injection-molding technique in which a die having a side gate structure is used as a resin-molding die. A major constituent of the resistance resin layer is selected from a polyphenylene sulfide resin, a polyphthalamide resin, and a liquid crystal polymer resin. In addition, the resistance resin layer also contains a mixture of carbon black and carbon fiber. Thus, the resistance resin layer has a specific volume resistance of 2 .OMEGA.cm or less in a direction along a central line of the cylindrical-shaped metallic base body. Both ends of the resistance resin layer are concentrically connected to ring-shaped metallic electrodes.Type: GrantFiled: March 20, 1997Date of Patent: May 4, 1999Assignee: Fuji Electric Co., Ltd.Inventor: Noriaki Kawada

Patent number: 5891534Abstract: Disclosed are improved components for a base rail system for the protection of fixtures such as display shelves, booths, and grocery store refrigeration cabinets. A protruding rotatable corner member rotatably engages objects that collide with the corner, reducing abrasion of the corner and of the object. In addition, the rotatable corner member redirects objects so as to reduce collision forces on the fixture protection system. Socket adapters closely receive a segmented, spheroidal rotatable member and rotatably couple the member to base rail protection members. A base rail protection member includes a single piece arcuate resilient sheath disposed over an arcuate channel member so as to form a cushioning gap therebetween for absorbing and dispersing collision forces. The arcuate sheath includes retaining grooves disposed along the length thereof for engaging tabs disposed along the arcuate channel member.Type: GrantFiled: December 31, 1996Date of Patent: April 6, 1999Assignee: McCue CorporationInventors: Douglas G. Sabin, David S. McCue, Christopher R. Hickey

Patent number: 5889093Abstract: The present invention provides an oxygen-absorbing resin composition, which is capable of sufficiently causing the oxygen-absorbing reaction even in a low-water environment, and also provides a packing material, packing method and package using such oxygen-absorbing resin composition.This invention is an oxygen-absorbing resin composition which contains a resin and an oxygen absorber which is made by coating iron powder with sodium iodide and potassium iodide. In a multi-layered film formed from this resin composition, iron particles coated with sodium iodide, etc. is dispersed in an oxygen-absorbing resin layer 4. Since a reaction accelerator of the oxygen absorber contains sodium iodide and potassium iodide as its principal component, this multi-layered film sufficiently absorbs oxygen in a low-water environment.Type: GrantFiled: February 3, 1997Date of Patent: March 30, 1999Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Hidetoshi Hatakeyama, Haruaki Eto
