Patent number: 6631609Abstract: A method for producing a cable or cable element from individual elements is provided. The method comprises heating the individual elements before or during a stranding process until they are at least close to plastification and cooling the individual elements to a solidification temperature of a plastic. A cable or cable element comprising individual elements that are twisted together to form the cable is also disclosed. The individual elements are heated either before or during a stranding process until they are at least close to plastification, and are subsequently cooled to a solidification temperature of the plastic until they leave a stranding machine. A stranding device for the production of a cable or cable element from individual elements is also disclosed. The stranding device comprises a heating device which acts on the individual elements and a cooling device located downstream of the heating device in a direction of processing.Type: GrantFiled: May 28, 2002Date of Patent: October 14, 2003Assignee: Drahtseilerei Gustav Kocks GmbH & Co.Inventor: Wolfgang Scheunemann

Publication number: 20030037529Abstract: The present invention includes a nontwisted composite tether comprising one or more composite rods encased in a jacket and a method for manufacturing same. A portion of the rods may be bundled into one or more strands, provided however that the rods comprising the strands are not twisted into twisted strands in the assembled nontwisted tether. Such untwisted strands, if any, additionally are not twisted relative to each other. Temporary and/or permanent buoyancy may be to the tether. The present invention includes methods for preparing, transporting, and installing a composite tether on a floating platform. The tether, preferably assembled at a waterfront, is launched into the water and towed to an offshore installation site, where the tether is upended and connected via a bottom end connector on the tether to an anchor foundation in the seabed and connected a top end connector on the tether to the floating platform.Type: ApplicationFiled: April 24, 2002Publication date: February 27, 2003Applicant: Conoco Inc.Inventors: Shaddy Y.

Patent number: 6460321Abstract: A racquet string comprises of a core surrounded by at least one sheath, having a plurality of sheath fibers wound around said core, and a coating resin uniting the core and sheath fibers into a unitary body. The sheath fibers are helically wound about the core at a high wind angle, i.e., at a wind angle between 25 and 40 degrees relative to the core axis. Preferably, the sheath comprises a plurality of main sheath fibers and a plurality of non-main sheath fibers, and the core, the main sheath fibers, and the coating resin are transparent. Preferably, the non-main sheath fibers have a relatively low transparency. In this manner, the non-main fibers produce a multi-helix appearance when the string is observed from the side.Type: GrantFiled: December 12, 1997Date of Patent: October 8, 2002Assignee: Gosen Co., Ltd.Inventors: Tatsumi Koshimae, Katsuo Kanno

Patent number: 6430913Abstract: A method of and an apparatus for making twisted electrical cable, such as 600 volt secondary distribution cable, and the twisted cable product are disclosed. The apparatus comprises a first plurality of stationary payoff reels each wound with a length of bare wire conductor. The conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the conductors during replacement of spent pay out reels. At least one extrusion process arranged downstream of the accumulator applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process. A cooling and/or curing trough through which water is flowed cools and/or cures the plastic insulation. A take-up accumulator arranged downstream of the cooling and/or curing trough accumulates a portion of each insulated conductor during changeover of the take-up reel arranged downstream of the take-up accumulator.Type: GrantFiled: May 19, 1999Date of Patent: August 13, 2002Assignee: Southwire CompanyInventors: Bobby C.

Patent number: 6009642Abstract: This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15).Type: GrantFiled: October 30, 1998Date of Patent: January 4, 2000Inventor: Gordon W. Nugent

Patent number: 5436075Abstract: Composite flexible multilayer insulation systems (MLI) were evaluated for thermal performance and compared with currently used fibrous silica (baseline) insulation system. The systems described are multilayer insulations consisting of alternating layers of metal foil and scrim ceramic cloth or vacuum metallized polymeric films quilted together using ceramic thread. A silicon carbide thread for use in the quilting and the method of making it are also described. These systems are useful to provide lightweight thermal insulation for a variety of uses, particularly on the surface of aerospace vehicles subject to very high temperatures during flight.Type: GrantFiled: November 9, 1992Date of Patent: July 25, 1995Assignee: The United States of America as represented by the Administrator of National Aeronautics and Space AdministrationInventor: Paul M.
