Patent number: 6773773Abstract: A fiber reinforced thermoplastic pipe member is obtained by a novel continuous process in which the reinforcement fibers are wrapped about the outer pipe surface in an unbonded condition while the pipe member continuously moves in a linear direction and which is followed by sufficient heating of the moving fiber wrapped pipe member to cause thermal bonding between the applied fibers and the pipe member. Automated apparatus for carrying out the continuous process is also disclosed.Type: GrantFiled: June 14, 1999Date of Patent: August 10, 2004Assignee: ADC Acquisition CompanyInventor: David Edgar Hauber

Patent number: 6753275Abstract: A multi-layered woven side air curtain has pre-configured air holding cavities and a polymeric film laminated thereto. An adhesive polyether polyurethane or polyester polyurethane prime coat layer is first coated onto a textile substrate, and then a polymeric film, such as polyamide, polyolefin, or polyurethane is laminated thereto. The textile substrate may be woven of nylon, polyester, or other synthetic fibers. According to an alternative embodiment, a multi-layered composite film product can be used as a film laminate without the need for a prime coat adhesive layer being first applied to the textile substrate. In such a case, the adhesive prime coat is applied to the textile substrate in a single step via the film laminate itself. The side air curtain can be pre-configured or prefabricated to numerous varied designs and shapes prior to coating.Type: GrantFiled: August 3, 2001Date of Patent: June 22, 2004Assignee: Bradford Industries, Inc.Inventor: Manuel J.

Patent number: 6746737Abstract: A hollow composite body includes a thermoplastic internal layer as a liner, a thermoplastic interlayer with embedded reinforcing fibers, and a thermoplastic external layer. The hollow body is made by furnishing the liner as a preform; introducing the preform into a mold, an inflatable bladder having been inserted into the preform; heating the preform and inflating the bladder to apply pressure against the internal wall of the preform. A space between the external wall of the preform and the internal wall of the mold is tailored to the thickness of the external layer of the hollow body to be obtained, so as to allow migration of the thermoplastic of the interlayer, and possible of the liner, beyond the interlayer.Type: GrantFiled: June 25, 2001Date of Patent: June 8, 2004Assignee: Saint-Gobain Vetrotex FranceInventors: Jean-Paul Debalme, Gilles Rocher

Patent number: 6743491Abstract: A laminated glass container has an inner layer of amber glass surrounded by an outer layer of flint glass. The container is manufactured by forming a cased glass stream, having an amber glass core and a flint glass casing layer, cutting the stream into individual gobs and molding the gobs into containers, all sufficiently rapidly that the amber glass does not have an opportunity chemically to react with the flint glass.Type: GrantFiled: August 22, 2003Date of Patent: June 1, 2004Assignee: Owens-Brockway Glass Container Inc.Inventors: Ronald A. Cirincione, W. Alan Poolos, Ronald T. Myers

Patent number: 6734123Abstract: The invention is directed to applying a plurality of polyurethane coating layers to a knit, woven or non-woven fabric substrate, following by sealing of two of such coated substrates together by radio frequency sealing, hot air sealing, or ultrasonic sealing to form an improved air-holding restraint system, such as an air curtain or air bag with superior air-holding characteristics.Type: GrantFiled: September 19, 2001Date of Patent: May 11, 2004Assignee: Bradford Industries, Inc.Inventors: Manuel J. Veiga, Richard J. Satin, Philip R. Rampolla, Leo Lizotte, Ryan Jennings

Patent number: 6716503Abstract: A method is disclosed for reinforcement of thin wall hollow thermoplastic storage vessels with one or more wraps of continuous fibers. This method requires thermal bonding between the reinforcement fibers and the outer surface of the thermoplastic storage vessel while the interior cavity of the storage vessel is being pressurized. The fiber wraps can also be oriented in spatial directions further resisting internal stress on the storage vessel walls when put in service.Type: GrantFiled: November 30, 2000Date of Patent: April 6, 2004Assignee: ADC Acquisition CompanyInventor: David E. Hauber

Patent number: 6709687Abstract: A generally transparent flexible packaging structure having an anti-transfer layer which, in a closed and sealed package, is at or close to an interior surface of the package. A contained food product in the package has a tendency to deposit a food product component on the interior surface of the packaging material and to thereby have a visually obscuring affect on transparency of the packaging structure. Anti-transfer material in the anti-transfer layer migrates to the interior surface of the package and interacts with the visually-obscuring component of the contained food product, thereby to attenuate or eliminate the visually obscuring effect of such component. Preferred primary polymer in the anti-transfer layer is EVA. Preferred anti-transfer materials include fatty acid esters and other amines and derivatives. The invention includes certain aspects of multiple layer packaging structures, closed and sealed packages, and methods of packaging food product.Type: GrantFiled: May 2, 2001Date of Patent: March 23, 2004Assignee: Curwood, Inc.Inventors: Gregory Robert Pockat, Richard Musil, Andrea M. Carlson, Kevin Nelson

Patent number: 6701971Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds.Type: GrantFiled: November 22, 2000Date of Patent: March 9, 2004Assignee: Mililken & CompanyInventors: John A.
