Patent number: 6492022Abstract: The present invention provides load leveling and impact energy absorption webbing comprising warp yarn. If the webbing is used in seat belts, the webbing provides load leveling behavior from about 450 pounds (about 2,000 Newtons) to about 1,800 pounds (about 8,000 Newtons) in vehicle collision. The yarn has a force-displacement profile such that: (a) when the yarn is subjected to an initial barrier stress of from about 0.2 gram/denier to less than or equal to about 1.4 grams/denier, the yarn elongates to less than 3 percent and the initial modulus ranges from about 20 grams/denier to about 150 grams/denier; (b) upon subjecting the yarn to greater than the initial barrier stress and less than or equal to 1.8 grams/denier, the yarn elongates further to at least about 10 percent and the energy absorbed from 0 to the elongation at 1.8 grams/denier is at least about 0.0008 Joule/denier·meter; and (c) upon subjecting the yarn to greater than 1.Type: GrantFiled: September 4, 2001Date of Patent: December 10, 2002Assignee: AlliedSignal Inc.Inventors: Weiming Tang, Frank Mares, Robert Clark Morgan

Patent number: 6414066Abstract: A composition comprising a binder and a residue wherein the residue comprises a blend of polypropylene, styrene butadiene rubber and calcium carbonate. The residue is a novel material derived as a coproduct from the medium-pressure depolymerization of nylon 6 carpet. The compositions are useful as road asphalt, asphalt roof membranes, molding compounds, and plastic lumber such as palisades and spacers.Type: GrantFiled: November 20, 2000Date of Patent: July 2, 2002Assignee: AlliedSignal Inc.Inventors: Kwok Wai Lem, Alan Letton, Thomas Paul John Izod, Francis Stephen Lupton, William Brian Bedwell

Patent number: 6403006Abstract: Polyethylene terephthalate yarn is prepared by spinning under high stress conditions in the transition region between oriented-amorphous and oriented-crystalline undrawn yarns by selection of process parameters to form an undrawn yarn that is a crystalline, partially oriented yarn with a crystallinity of 3 to 15 percent and a melting point elevation of 2 to 10° C. The spun yarn is then hot drawn to a total draw ratio between 1.5/1 and 2.5/1 with the resulting properties: (A) a terminal modulus of at least 20 g/d, (B) a dimensional stability defined by E4.5+FS<13.5 percent, (C) a tenacity of at least 7 grams per denier, (D) a melting point elevation of 9 to 14° C., and (E) anamorphous orientation function of less than 0.75. The resulting treated tire cord provides high tenacity in combination with improved dimensional stability.Type: GrantFiled: May 16, 2000Date of Patent: June 11, 2002Assignee: AlliedSignal Inc.Inventors: Charles Jay Nelson, Jayendra Hiralal Bheda, Peter Bryan Rim, James Michael Turner

Patent number: 6361720Abstract: I have developed an agglomeration process by which granules are formed by the steps of: (a) injecting polymer having sufficient viscoelasticity, and (b) impacting particles on the polymer at the injection point. The present invention is advantageous because it overcomes the problems of previous granulation process and subsequent art processes by having a very low recycle rate and allowing for control of granule size. It is particularly useful for fertilizer granule formation using a ureaform polymer and particles comprised of ammonium sulfate.Type: GrantFiled: December 28, 1999Date of Patent: March 26, 2002Assignee: Honeywell International Inc.Inventor: Ronald Earl Highsmith

Patent number: 6341708Abstract: Blast resistant and blast directing container assemblies for receiving explosive articles and preventing or minimizing damage in the event of an explosion. The container assembly includes an opening covered by a band of blast resistant material with at least one slit therethrough in the hoop direction of the band, and optionally, a blast mitigating material located within the container. The container can be collapsible for storage when empty. The container assemblies have utility in aircraft where weight is an important consideration, more particularly as cargo holders or containment devices in the passenger cabin. They are also particularly useful to bomb squad personnel as transport devices for hazardous materials such as gunpowder, high explosives and combinations of high explosives with shrapnel, e.g., grenades and pipe bombs.Type: GrantFiled: May 28, 1999Date of Patent: January 29, 2002Assignee: AlliedSignal Inc.Inventors: Igor Palley, Gary Allan Harpell, Max Wilhelm Gerlach

Patent number: 6340524Abstract: The present invention provides a yarn having a force-displacement profile such that: (a) when the yarn is subjected to an initial stress barrier of from about 0.8 gram/denier to less than or equal to about 1.2 grams/denier, the yarn elongates to less than 5 percent and has an initial modulus in the range from about 30 grams/denier to about 80 grams/denier; (b) upon subjecting the yarn to greater than the initial stress barrier and to less than or equal to about 1.5 grams/denier, the yarn elongates further to at least about 8 percent; and (c) upon subjecting the yarn to greater than 1.5 grams/denier, the modulus increases sharply and the yarn elongates further until the yarn breaks at a tensile strength of at least about 6 grams/denier, wherein the yarn comprises a multiplicity of fibers, all of the fibers have substantially the same force-displacement profile, and are made from polymers having a glass transition temperature in the range from about −40° C. to about +70° C.Type: GrantFiled: May 1, 2001Date of Patent: January 22, 2002Assignee: AlliedSignal Inc.Inventors: Weiming Tang, Frank Mares, Robert Clark Morgan

Patent number: 6150019Abstract: This invention provides improved methods and compositions for achieving material coloration using particle scattering. These coloration effects can be designed to be either highly stable or dependent upon the switching effects of either temperature, integrated thermal exposure, moisture absorption, or exposure to actinic radiation. Articles employing materials with these coloration effects are described. Composition comprise a solid, light-transmitting matrix component having a non-liquid particle scattering colorant dispersed. Articles are produced wherein another solid second matrix component has an electronic transition colorant dispersed therein and the first and second compositions are disposed on one another and optionally interpenetrate each other. Colored articles are produced in the form of fibers, films and molded articles.Type: GrantFiled: June 23, 1999Date of Patent: November 21, 2000Assignee: AlliedSignal Inc.Inventors: Tammy Lynn Smith, Ray Baughman, Mary Frances Martin, Wonsik Choi, Jeffrey Moulton
