Patent number: 6596289Abstract: A garment for treating the skin, a method of making the garment and a method of using the garment to treat the skin, made of garment material, in particular hose material to be worn tightly against the skin, which has a multiplicity of durable chemical bonding sites. The durable sites which are preferably of the type to make covalent bonds, are bound to binding molecules which form chemical hooks for the garment material. Each of the chemical hooks has one or more semi-durable chemical bonding sites of the type which can chemically bond an active ingredient molecule to the binding agent but which is broken in the presence of skin conditions which are normal such as normal skin pH, normal skin moisture and normal skin heat generated both by body heat and the heat of friction of the garment rubbing against the skin. Active ingredient molecules such as molecules of theophylline or theophylline complexes are bound to the binding agent and are released to the skin when the garment is worn.Type: GrantFiled: July 27, 2000Date of Patent: July 22, 2003Inventor: Peter T. Pugliese

Publication number: 20030113565Abstract: Weatherproof sheets, suitable for conventional printing, writing, photocopying, and laser printing, are prepared by impregnantly coating a cellulosic substrate on at least one side with a durable weatherproofing composition that is water-based. The composition that is used for general-purpose weatherproof sheets comprises a styrenic acrylic copolymer, a wax, a filler for blocking resistance, a filler for tooth, and a pigment. The preparation of all-purpose weatherproof sheets, usable in photocopiers and laser printers, is made possible by substantially omitting calcium carbonate and titanium dioxide from the composition. The weatherproof sheets resist falling apart, remain legible, and can be written upon when wet. They are also non yellowing, biodegradable and recylclable. Also, disclosed are methods for making the weatherproof sheets, as well as weatherproof sheets made by those methods.Type: ApplicationFiled: December 17, 2001Publication date: June 19, 2003Applicant: J.L. Darling CorporationInventors: Scott E. Silver, Todd D. Silver, Dennis Oscar

Patent number: 6552536Abstract: A reference standard and method for inspecting dual-layered coatings. The reference standard has a first layer adherent to a substrate, the first layer has a predetermined thickness that increases in one direction. Adherent to the first layer is a second layer, the second layer has a predetermined thickness that increases in a direction orthogonal with the first layer. The orientation of the first and second layers of the reference standard provides a spectrum of the possible variations of the dual-layered coating.Type: GrantFiled: June 17, 2002Date of Patent: April 22, 2003Assignee: General Electric CompanyInventor: Richard L. Trantow

Patent number: 6294265Abstract: Composite cellulose containing materials which are waterproof and biodegradable are produced which consist essentially of cellulose and hydrophobic polymer-based composition in the amount about 4 to 40 wt %. The polymer-based composition comprises first polymer, which is partially saponified polyvinyl acetate, second polymer, which functions as plasticizer for improving elasticity of the first polymer and cross-linking agent, which is capable to cross-link the first polymer. The polymer-based composition may additionally contain environmentally friendly hydrophobizators, fillers and pigments.Type: GrantFiled: September 23, 1999Date of Patent: September 25, 2001Assignee: Rademate Ltd.Inventors: Michael Ioelovich, Oleg Figovsky

Patent number: 6170426Abstract: Apparatus and methods for producing dry, wet or partially wet and partially dry segments of tissues. The tissue dispenser generally comprises a housing having a tissue egress passage, a tissue source of a predetermined quantity of dry tissue located in the housing, a fluid source of a predetermined volume of fluid located in the housing, and an actuatable application mechanism in fluid communication with the fluid source and operationally positioned proximate to the tissue egress passage. The application mechanism can be actuated to dispense fluid onto the tissue as the tissue passes through the tissue egress passage. A partially wet and partially dry tissue can be used to clean and dry an article. The tissue may generally comprise a cleansing pad having an impermeable membrane positioned between two tissue segments to form a wet tissue area and a dry tissue area. The impermeable membrane prevents fluid from bleeding into the dry tissue area. The tissue may also comprise a pad attached to a bubble of fluid.Type: GrantFiled: October 2, 1998Date of Patent: January 9, 2001Inventor: Arden L. Thorsbakken

Patent number: 6153040Abstract: A process for reducing rollups in gypsum board panels when the panels are laminated with a laminate, is provided. A laminator is provided, as is at least one gypsum board panel, each panel having a face paper layer and a backing paper layer. Each paper layer has a coefficient of friction, and at least one of the face paper layer and the backing paper layer is treated with an agent for reducing the coefficient of friction and water absorbency. Next, a supply of laminate is provided and installed in the laminator. Then, at least one panel of the gypsum board is fed through the laminator, so that a layer of the laminate is applied thereon.Type: GrantFiled: May 15, 1998Date of Patent: November 28, 2000Assignee: United States Gypsum CompanyInventors: Evan V. Rohlf, Dick C. Engbrecht, Mark B. Scalf
