The reflective insulation system includes a reflective layer such as aluminum, a layer of fiberglass, and a layer of vapor retarding material. A first side of the layer of fiberglass is bonded to the reflective layer by a deposit of hot melt glue. The second side of the layer of fiberglass is bonded to the layer of vapor retarding material by a second deposit of hot melt glue. The vapor retarding layer may be a plastic material, such as polypropylene or a reflective material, such as aluminum.Type: GrantFiled: February 26, 2002Date of Patent: September 28, 2004Assignee: CGI Silvercote Inc.Inventors: Lawrence Zupon, David Dejarlais, James Gambatese, Stephen Neff

Patent number: 6746976Abstract: Disclosed are thin until wet materials that are suitable for use as acquisition members for absorbent articles (e.g., diapers, catamenial products, and adult incontinence devices). Preferred materials according to the present invention are either: 1) fibrous assemblies that utilize wet strength means to stabilize the material or 2) compressed regenerated cellulosic sponges so that, when the material is saturated with an aqueous fluid, it has an expanded wet density of between about 0.04 grams/cm3 and about 0.4 grams/cm3 and an expanded capillary desorption height of less than about 25 cm and a temporary binding means that helps maintain the material at a compressed dry density between about 0.06 grams/cm3 and about 1.2 grams/cm3 until the material is exposed to an aqueous fluid. The ratio of the compressed dry density to the expanded wet density is also greater than about 1.5:1. A suitable process for making the materials and absorbent structures using the materials are also disclosed.Type: GrantFiled: September 20, 2000Date of Patent: June 8, 2004Assignee: The Procter & Gamble CompanyInventors: Edward Joseph Urankar, Gerald Alfred Young, Mattias Schmidt, James Albert Cleary, Matthias Konrad Hippe, Giovanni Carlucci

Publication number: 20030228814Abstract: An antibacterial packaging material including a layer comprising matted cellulosic fibers is disclosed. The layer comprising matted cellulosic fibers has opposed surfaces, and a hop acid selected from alpha-acids, beta-acids, and mixtures thereof is dispersed in the fibers and between the opposed surfaces. A coating of polymeric material (e.g., a polyolefin) may be disposed on the layer comprising matted cellulosic fibers to provide a coated material. The antibacterial packaging material is useful in that the growth of gram positive spore-forming bacteria such as Clostridium and/or Bacillus (e.g., Bacillus anthracis) within or on the material is inhibited. In another form, a hop acid is disposed on at least a portion of one of the surfaces of the layer comprising matted cellulosic fibers. A coating of polymeric material is disposed over the hop acid and at least over a portion of one of the surfaces of the layer comprising matted cellulosic fibers.Type: ApplicationFiled: June 7, 2002Publication date: December 11, 2003Inventors: Michael C. Barney, David S. Ryder, John R. Seabrooks

Publication number: 20030224682Abstract: A gasket to seal a service door of an appliance. The gasket is formed from a needled glass mat attached to a glass paper by random needling. The mat is very compressible to seal the door to the appliance to prevent the entrance of flammable vapors and the egress of exhaust. The glass paper provides structural strength and carries a vermiculite coating that protects the surface nearest the flame. Random needling retains the structural strength of the product to prevent it from tearing.Type: ApplicationFiled: June 3, 2002Publication date: December 4, 2003Inventors: William John Luerman, Dorothy Jean Stuart

Publication number: 20030211800Abstract: A composite nonwoven fabric manufactured by joining a fibrous web that comprises wood fibers, or a mixture of wood fibers and synthetic fibers, to a spunlaid or other nonwoven baseweb by means of a hydroentanglement process. The spunlaid nonwoven web, which may be made of a polyester such as a poly (ethylene terephthalate) or of a polyolefin such as polypropylene, is a less-than-fully bonded web, which may be produced by a method in which the thermal calendering is effected at lower than normal temperatures, in particular temperature lower than the melting point or softening point of the polymeric material from which the spunlaid nonwoven web is made. The strength of the composite fabric may be significantly greater than that of the spunlaid nonwoven web itself, in certain embodiments the base web contributes no more than about 45% of the strength of the composite fabric.Type: ApplicationFiled: February 10, 2003Publication date: November 13, 2003Inventors: Graham Kirk Duncan, Alan William Meierhoefer, Raymond Anthony Volpe

Publication number: 20030203694Abstract: Disclosed is a filter medium having at least a first layer containing a stabilized matrix of thermoplastic filaments and at least one secondary material; and a second layer having a stabilized matrix of thermoplastic filaments and optionally of at least one secondary material. Each of the layer of the filter medium has a different compositional ratio of the components to result in a gradient structure. The compositional gradient for the layers of the coform results in a filter having improved capacity, which extends the life of the filter medium, as compared to a filter without the compositional gradient. The present invention also provides a method of removing particles from a fluid containing particles. The method of the present invention includes contacting the fluid containing particles with the filter medium of having the two layers described above in a manner such that the fluid containing particles is passed through the first layer of the filter medium before the second layer.Type: ApplicationFiled: April 26, 2002Publication date: October 30, 2003Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Ganesh Chandra Deka, Ronald C. Cox
