Patent number: 5492580Abstract: A method of making a moldable, nonwoven composite material. The method includes blending a mix of first fibers and second thermoplastic fibers. The second fibers have a melting point lower than that of the first fibers and comprise approximately 40-80 percent of the blend. The blend is then processed into a fibrous batt. The batt is then consolidated into a nonwoven structure with the first fibers being thoroughly intermixed with the second fibers. The nonwoven structure is then heated to a temperature below the melting point of the first fibers and above the melting point of the second thermoplastic fibers to substantially liquefy the second fibers and form a thermoplastic resin. The heated nonwoven structure is compressed to flow the liquefied resin to displace air voids in the nonwoven structure and encapsulate the first fibers. Finally, the nonwoven structure is cooled to form a composite material having substantially reduced air voids therein with the first fibers thoroughly encapsulated by the resin.Type: GrantFiled: September 13, 1994Date of Patent: February 20, 1996Assignee: Gates Formed-Fibre Products, Inc.Inventor: George A.

Patent number: 5374387Abstract: A process is provided for producing elastomeric compositions by forming a mixture of polymeric material, a reinforcing agent, a processing aid and a vulcanizing agent. The process of the invention is continuous and includes the repeated, sequential steps of admixing the polymeric material along a first mixing zone defined by a space wherein the gross energy applied induces a first operating temperature range. The mixture of the first zone is continuously passed into and through a second mixing zone while adding and admixing the reinforcement agent and processing aid therewith, the second mixing zone being defined by a space wherein the gross energy applied induces a second operating temperature range. The mixture of the second zone is then continuously passed into and through a third mixing zone while adding and admixing the vulcanizing agent therewith, the third mixing zone being defined by a space wherein the gross energy applied induces a third operating temperature range.Type: GrantFiled: January 29, 1993Date of Patent: December 20, 1994Assignee: The Gates Rubber CompanyInventors: Roger P.

Patent number: 5327963Abstract: A coupling device is adapted for attachment to an elastomeric tubular body having integral, looped reinforcement fibers as part of a tubular assembly. The coupling device includes a coupling member, a stem and a mechanism for retaining the elastomeric tubular body in sealing engagement with the stem when connected therewith. The retaining mechanism maintains this engagement by being interposed within loops of the reinforcement fibers to limit axial movement of the reinforcement fibers relative to the stem. Thus, the grommet retained coupling and the elastomeric tubular body are maintained in spaced relation to and sealing engagement with each other.Type: GrantFiled: October 30, 1991Date of Patent: July 12, 1994Assignee: The Gates Rubber CompanyInventors: James C. Vance, Sr., Roy G. Quinlan
