Patent number: 6998023Abstract: Papermachine clothing comprising a woven or non-woven support layer, a non-woven layer comprising ultra-coarse non-continuous fibers orientated close to the intended running directions of the clothing and two further layers of batt each comprising conventional somewhat finer staple fibers predominantly aligned close to the cross-machine direction. The ultra-coarse non-continuous fiber layer may comprise two such layers, one of which is biassed at an angle A to the running direction X of the clothing, the other of which is biased at an opposite angle B to the running direction X to provide a layer whose fibers while being substantially orientated in the machine direction also have a bi-axial construction with a cross-orientation.Type: GrantFiled: October 18, 2001Date of Patent: February 14, 2006Assignee: Voith Fabrics Heidenheim GmbH & Co. KGInventor: Robert L. Crook

Patent number: 6989080Abstract: A nonwoven papermaker's fabric, usable in the dryer section of a paper machine, has a spiral wound machine direction (MD) base layer of raw stock which is wound around a pair of parallel rolls or cylinders until the desired length and width is achieved. The spiral wound MD layer is overlaid with a cross-machine direction (CD) layer of similar or dissimilar raw stock and mated by any of a number of means. The spiral wound MD layer can also be mated to another MD layer spiraled in the opposite direction and in one embodiment further mated to a CD layer. The fabric is preferably produced so that its neutral line is oriented toward the paper side of the fabric so that the paper sheet will stretch less than when typical dryer fabrics are used to turn the paper sheet and fabric around the dryer cylinders.Type: GrantFiled: June 19, 2003Date of Patent: January 24, 2006Assignee: Albany International Corp.Inventor: Robert A.

Patent number: 6986921Abstract: The present invention is directed to thermoplastic elastomer films and bags made from thermoplastic elastomer films and also to methods for making thermoplastic elastomer films and bags. The thermoplastic elastomer films of the present invention are composed of thermoplastic elastomers and non-elastic polyesters. The bags of the present invention are fabricated using blended monolayer thermoplastic films that include a blend of thermoplastic elastomer and a non-elastic polyester, or co-extruded multi-layer films that include at least one layer of thermoplastic elastomer and at least one layer of non-elastic polyester. The blended monolayer thermoplastic films of the present invention are useful in the food handling industry and particularly in the meat packaging industry and for use in cooking bag applications. The co-extruded films of the present invention are also useful in the food handling industry and particularly the meat packaging industry and for use in meat casing applications.Type: GrantFiled: November 12, 2003Date of Patent: January 17, 2006Inventors: Michael D. Schmal, Ernest E. Bachert, John A. Menges, Robert R. Witt

Patent number: 6949280Abstract: A sheet of unidirectionally-oriented fiber strands includes unidirectional fibers, bonding fibers interwoven with the unidirectional fibers to form a fiber panel, and thermoplastic film laminating the fiber panel there between. In one embodiment, a second sheet of laminated unidirectional fibers is joined to the first sheet of laminated unidirectional fibers with the unidirectional fibers running in a second direction as compared to the first fibers. In yet another embodiment, individual laminated sheets of unidirectional fibers are stitched together to form packets of sheets which may be used singularly or multiple packets may be bundled together.Type: GrantFiled: April 22, 2003Date of Patent: September 27, 2005Assignee: Survival, IncorporatedInventors: Lee Walker Brillhart, III, Ricky William Stewart, Ronald G.

Patent number: 6914021Abstract: This invention relates to airships, with a volume of 15 to 60 million cubic feet of Helium. More particularly, it relates to improved structural envelope/gas bags or outer covers for lighter-than-air and neutral buoyancy airships. In detail, the material is a multi-layer cloth assembly including at least two plies of fiber cloth, said cloth comprising 56 by 56 yarns/inch with a total weight of 150 to 450 g/m2, with the fiber of the individual cloth layers having a denier generally between 180 and 280 and with the fill of the individual plies at 90 degrees to each other. Preferably, the filaments should be between 200 and 215 denier. The fibers of each layer of cloth are selected from the group consisting of extended chain polyethylene polymer or a thermotropic liquid (melt spun) crystalline polymer. The extended chain polyethylene fiber is a woven modified rip stop weave architecture, while the thermotropic liquid (melt spun) crystalline polymer fiber is a 2×2 basket weave architecture.Type: GrantFiled: July 26, 2001Date of Patent: July 5, 2005Assignee: Lockheed Martin CorporationInventor: Donald R.
