Patent number: 6583241Abstract: The present invention is directed to producing a resin which, when formed into a film, has excellent gas barrier and/or moisture barrier (low MVTR) properties. Further, the resin has a relatively high molecular weight distribution, preferably above 6, and has excellent processability/extrudability. The resin is produced using a cyclopentadienyl chromium compound, preferably a mono CpCr compound, on a support, preferably a silica support. A particularly preferred catalyst for use in the present invention comprises pentamethylcyclopentadienyidimethylchromiumpyridine. Preferably, the catalyst is used in a slurry polymerization process.Type: GrantFiled: March 15, 2001Date of Patent: June 24, 2003Assignee: Chevron Phillips Chemical Company LPInventors: David L.

Patent number: 6531565Abstract: A process is disclosed for producing polyethylene resin of broad molecular weight distribution, when formed into a film, high barrier to moisture (low MVTR (Moisture Vapor Transmission Rate) for the film). The resin is formed by polymerizing ethylene, preferably in a gas phase process or in a slurry process, using a post-titanated catalyst, that is, a catalyst wherein after initial formation of a catalyst comprising Cr—Ti-inorganic refractory support, further titanium is added to the catalyst in a post-titanation step, preferably to increase the titanium content of the catalyst to a final level preferably between 7 and 9.5 wt. %.Type: GrantFiled: March 15, 2001Date of Patent: March 11, 2003Assignee: Chevron Phillips Chemical Company LPInventors: Gene E.

Patent number: 5378003Abstract: A creeper for supporting the body of a worker and facilitating movement of the worker under and around an object such as an automobile. The creeper comprises a platform having a top surface and an underside, and four corner casters mounted on the underside of the platform for spacing the platform above a generally flat horizontal floor and for facilitating rolling of the platform on the floor. The casters are so spaced with respect to the platform that lines connecting adjacent casters define a quadrangle with a corresponding caster at each corner of the quadrangle. A fifth caster is mounted on the underside of said platform within said quadrangle.Type: GrantFiled: May 20, 1993Date of Patent: January 3, 1995Assignee: Koller Enterprises, Inc.Inventors: Wayne D.

Patent number: 4813501Abstract: A rotary bit which includes a bit body having a tapered, externally threaded neck located at one side of the bit body. The bit body includes three, flat, lateral side faces which extend at 120.degree. to each other and thus lie in planes which would contain sides of an equilateral triangle. Groups of cutter supporting blocks are built-up on the bit body at circumferentially spaced intervals therearound and on the opposite side of the bit body from that from which the tapered neck extends. Each of the cutter supporting blocks defines a generally cylindrical bore for the purpose of slidably and rotatably receiving a cutter element in such bore. The several cutter elements thus mounted in the blocks are arrayed around a centrally located pilot cutter which is mounted on the bit body at a central location and in axial alignment with fluid passageways and ports which extend through the tapered neck and the bit body.Type: GrantFiled: December 2, 1987Date of Patent: March 21, 1989Assignee: Mills Machine CompanyInventors: Charles D.
