Publication number: 20090178248Abstract: The invention provides a clamp assembly for holding a set of seal elements to a rail, the assembly including an arm sub-assembly and a locking mechanism. The arm sub-assembly includes first and second arms which are pivotally attached by a pin. The first arm includes an elongate first link portion and a first engagement portion extending substantially transversely to the first link portion. The first engagement portion includes a first contact part which is adapted to engage a selected one of the set of seal elements. In addition, the second arm includes a second link portion and a second engagement portion extending substantially transversely to the second link portion. Also, the second engagement portion includes a second contact part adapted to engage another one of the set of seal elements.Type: ApplicationFiled: January 16, 2009Publication date: July 16, 2009Applicant: PERFORMANCE POLYMERS INC.Inventors: Andrei BUTA, Frank Drayton WILLIAMS

Patent number: 6877671Abstract: The roadway at a road-rail crossing comprises rows of extruded rubber strips. The strips have a tongue-and-groove type of edge connection, which constrain the strips such that if one strip bounces the adjacent strips bounce too. Locking-strips fit between primary-strips, and have latches, which snap into place upon the locking-strips being driven downwards, from above.Type: GrantFiled: October 16, 2002Date of Patent: April 12, 2005Assignee: Performance Polymers Inc.Inventors: Dominicus Bruyn, Frank Drayton Williams, Bill Wei Shiu Chien

Patent number: 6701594Abstract: At a crossing, rubber interface strips are positioned between the rails and the asphalt or concrete. A U-shaped spring-clip fits underneath the rail, and has upstanding arms that carry tappets, which engage the strips. One of the arms is threaded, and carries a screwed tappet-rod. Turning the tappet-rod closes the distance between the tappets, clamping the strips onto the sides of the rail, and forcing the springy arms apart. The spring-clips are manipulated into position while in an unstressed condition. The spring-clip is only brought up to force when finally assembled. Assembly can be done without tools, and with little danger of mix-assembly, or of injury to workers.Type: GrantFiled: February 19, 2002Date of Patent: March 9, 2004Assignee: Performance Polymers Inc.Inventor: Dominicus Bruyn

Patent number: 6250562Abstract: Pre-cast concrete panels are commonly provided at road-rail crossings, to serve as the roadway, but such panels have been liable to premature failure. Rubber caps are placed over the cross-ties, between the panel and the ties, to isolate the panel from the stresses that arise when the panel contacts the ties directly. The caps are ribbed. Two kinds of ribs are provided, some solid and rectangular, others triangular and hollow. The ribbed panels provide resilience and hysteresis over a range of conditions, to prevent fretting and cracking of the panel.Type: GrantFiled: August 25, 1999Date of Patent: June 26, 2001Assignee: Performance Polymers Inc.Inventor: Dominicus Bruyn

Patent number: 5899379Abstract: At a road/rail crossing, rubber inserts are located alongside the rails, between the rail and the asphalt of the road. The insert has a resilient nose, which engages the under-face of the head of the rail. The insert does not touch the web of the rail, but rather the insert is wedged between the head and the flange of the rail. This engagement assists in locking the insert to the rail, by self-locking-taper action.Type: GrantFiled: October 27, 1997Date of Patent: May 4, 1999Assignee: Performance Polymers Inc.Inventors: Dominicus Bruyn, Frank Drayton Williams, Bill Wei Shiu Chien

Patent number: 4918127Abstract: A halogen-free filled elastomer blend composition, containing at least two elastomers from the group: elastomeric ethylene-propylene copolymers and terpolymers, polyamide elastomers, elastomeric polyesters, isobutylene polymers, polyurethane elastomers, acrylic elastomers, natural rubber, polybutadiene and polyisoprene, as minor components, and a flame-retardant halogen-free inorganic filler as the major component.Type: GrantFiled: February 23, 1989Date of Patent: April 17, 1990Assignee: BP Performance Polymers, Inc.Inventors: Ashok M. Adur, Charles D. Shedd

Patent number: 4833195Abstract: A thermoplastic pelletizable polymer composition comprising an oligomer or degraded polyolefin and an olefinic elastomer. Optionally, the composition can also include a polyolefin thermoplastic polymer. The composition, when converted to a film or fabric meets the criteria or drapability, low hardness on the Shore A scale, high melt flow and reprocessability.Type: GrantFiled: July 20, 1987Date of Patent: May 23, 1989Assignee: BP Performance Polymers, Inc.Inventors: Ashok M. Adur, Joseph M. Hogue, Jr.

Patent number: 4696967Abstract: A low smoke and flame retardant composition comprising an acrylate rubber and a polyolefin resin compatibilized with aluminum trihydrate. The composition can be made by dynamically partially curing blends of acrylate rubber and polyolefin resin with compatibilizing amounts of aluminum trihydrate to yield a thermoplastic elastomer with improved properties at elevated temperatures. The acrylate rubber can comprise an acrylate ester polymer or a copolymer of acrylate ester with ethylene. The polyolefin resin is preferably a high molecular weight polymerization product of either ethylene or propylene, preferably propylene.Type: GrantFiled: November 6, 1986Date of Patent: September 29, 1987Assignee: BP Performance Polymers Inc.Inventors: Charles D. Shedd, David J. Anzini
