Patent number: 6268037Abstract: The present invention relates to a method for making a shielded automobile component and the shielded automobile component itself. The component includes a composite formed of a metal sheet which includes protrusions which extend from a surface of the metal sheet and a blow-molded thermoplastic layer formed around the protrusions which fixes the blow-molded layer to the metal sheet during the molding process. The protrusions on the metal sheet define plain polygonal areas which are free of protrusions.Type: GrantFiled: October 28, 1998Date of Patent: July 31, 2001Assignee: Acoust-A-Fiber Research and Development, Inc.Inventors: Richard M. Butler, Hiten T. Shah

Patent number: 6148955Abstract: A silencer and method of making are described. A tube is wrapped with a layer of texturized fiber yarn. A septum is then overlaid. Other layers of fiber and septums may also be added. Once rolling is completed, the roll is placed in a canister with end caps.Type: GrantFiled: June 7, 1999Date of Patent: November 21, 2000Assignee: Acoust-A-Fiber Research and Development IncInventors: Jerry M. Wolf, Hiten T. Shah

Patent number: 6094817Abstract: Method of filling a silencer with a sound insulating material includes inserting a nozzle into a silencer and feeding sound insulating material, preferably continuous texturized glass, or basalt, or mineral fiber, through the nozzle into the silencer. The nozzle reciprocates linearly and retracts from the silencer while the fibers are being fed into the silencer. The silencer may be rotated while the sound insulating material is fed into the silencer. The nozzle is reciprocated into and out of the silencer and the silencer rotated clockwise or counter-clockwise to control the density and distribution of fill.Type: GrantFiled: October 15, 1998Date of Patent: August 1, 2000Assignee: Acoust-A-Fiber Research and Development, Inc.Inventors: Hiten T. Shah, Tommy E. Rice, James M. Miller

Patent number: 6045717Abstract: Concentric conduits are supplied for the purpose of minimizing heat transfer from within the inner conduit through the outer conduit. The air gap or annulus around the inner conduit is filled with a resin mixture which is mixed with vermiculite and mineral fiber to form a slurry. The slurry is pumped into an open end of the annulus to fill the annulus and enhance the heat insulation characteristics of the concentric conduits.Type: GrantFiled: February 10, 1998Date of Patent: April 4, 2000Assignee: Acoust-A-Fiber Research and Development, Inc.Inventors: Jerry M. Wolf, Hiten T. Shah, Steven J. Crosbie, James D. Crosbie

Patent number: 6026846Abstract: A hot pipe from an automobile manifold is shielded from other components in the engine compartment by attaching a two part shield around the pipe and clamping it in place. Each part is formed of two sheets of metallic material sandwiching therebetween a fibrous layer of heat insulating material. The layers of each of the shield parts are formed to a shape to conform to the shape of the hot pipe to be shielded prior to installation.Type: GrantFiled: February 10, 1998Date of Patent: February 22, 2000Assignee: Acoust-A-Fiber Research & Development, Inc.Inventors: Jerry M. Wolf, Hiten T. Shah

Patent number: 5603297Abstract: A heat shield formed of composite layers of reflective metallic foil, heat insulating fibers and a non-electrically conducting sheet molding compound which are deformed to the general shape of an operating apparatus. The shield is then clamped about the operating apparatus in spaced relationship between the operating apparatus and a high temperature heat source to prevent heat radiation to the operating apparatus.Type: GrantFiled: January 18, 1996Date of Patent: February 18, 1997Assignee: Acoust-A-Fiber Research and Development, Inc.Inventors: Jerry M. Wolf, Hiten T. Shah

Patent number: 5464952Abstract: A shield for mounting on a vehicle intermediate the passenger compartment and the exhaust system is formed as a sandwich of a fibrous layer between two heat reflecting layers. During the manufacturing process a hardenable resin impregnates the periphery of the fibrous layer and hardens in place to serve as an adhesive for bonding the layers together and providing a hard rigid mounting bracket. The fibrous layer intermediate its peripheral edges is relatively loosely held in place to serve as a sound absorbing barrier.Type: GrantFiled: March 23, 1995Date of Patent: November 7, 1995Assignee: Acoust-A-Fiber Research and Development Inc.Inventors: Hiten T. Shah, Jerry M. Wolf
