The nonwoven fleece layer is a needled blend of natural fibers and synthetic fibers having a uniform density and working surface, resulting in a better polishing or finishing consistency. The material can withstand high heat levels and can be worked quickly, resulting in a more efficient polishing or finishing operation. The buff material can be converted into any preferred shape or tool, such as an endless belt, disc, flapwheel, or spiral band.Type: GrantFiled: December 22, 2000Date of Patent: March 30, 2004Assignee: Freudenberg Nonwovens Limited PartnershipInventor: Gerald F. Kruegler

Publication number: 20040048535Abstract: Composite structures and methods are taught relating to temperature stabilizing saddle pads, horse blankets, saddle girths, saddle seat cushions, and saddles for protection and increased performance of horses and/or riders, among other similar products. The invention provides for products that stabilize the temperature of the horse and/or the rider by absorbing heat generated by the body of the horse and/or rider when the temperature exceeds a preset temperature appropriate for the product. In this process heat energy is absorbed through phase change, resulting in a constant temperature as long as there is material that has not changed phase.Type: ApplicationFiled: September 3, 2003Publication date: March 11, 2004Inventor: Richard J. Sacks

Publication number: 20040048542Abstract: A nonwoven fabric includes a first composite layer that includes from about 50% to about 90% by weight non-thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. A preponderance of the fibers at a first outer surface of the first composite layer comprise non-thermoplastic absorbent staple fibers and a preponderance of the fibers at a second outer surface of the first composite layer comprise thermoplastic fibers. The nonwoven fabric further includes a second composite layer that includes from about 50% to about 90% by weight non-thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. The second composite layer is adjacent the second outer surface of the first composite layer.Type: ApplicationFiled: September 9, 2002Publication date: March 11, 2004Inventors: Craig F. Thomaschefsky, Lawrence M. Brown

Publication number: 20040038014Abstract: Improved filtration media or filter bodies can be made from fine fiber and can be formed into a filtration structure having no internal defects. The filter media or filter body comprises a collection of spot in fiber with defined fiber diameter, layer thickness and media solidity. The fine fiber is formed into a media body and obtains substantial flux and filtration efficiency. The filtration media or body can comprise single or multiple layers of fine fiber combined into the improved filter body.Type: ApplicationFiled: April 7, 2003Publication date: February 26, 2004Applicant: Donaldson Company, Inc.Inventors: James W. Schaefer, Marty A. Barris, Thomas M. Weik

Publication number: 20040038008Abstract: A pliable pad includes a layer formed of an absorbent material and a formable material arranged generally parallel to each other. The selected formable material, such as aluminum foil, is capable of assuming a desired shape and of retaining the desired shape which has been assumed. As a result, the formable material can be shaped so that the pliable pad defines a basin for collecting and absorbing liquids. The pliable pad can also include one or more layers for defining a liquid barrier. The pliable pad can be used to collect excess liquid produced during a medical procedure, such as the irrigation of a wound, or can be used in other, non-medical applications in which liquid is to be collected.Type: ApplicationFiled: April 17, 2003Publication date: February 26, 2004Inventors: Daniel S Levine, David E Lavine, Marshall S Lavine
