Patent number: 4789708Abstract: Ethylene propylene copolymer elastomers and ethylene propylene diene terpolymer elastomers are shown which, when cured, exhibit improved oil resistance and chemical aging properties at elevated temperatures and pressures. A previously polymerized liquid 1,2-polybutadiene is incorporated into the elastomer by chemical blending during the polymerization process. Such compositions are useful as electrical insulating materials for use under extreme environmental conditions, particularly in wire and cable constructions.Type: GrantFiled: December 14, 1987Date of Patent: December 6, 1988Assignee: Hughes Tool CompanyInventor: Raymond L. Guzy

Patent number: 4658089Abstract: An electrical cable for a submersible well pump has an internal fabric layer for providing additional hoop strength. The cable has a plurality of conductors. Each conductor is surrounded by an insulating layer that is permeable to gas. A woven fabric layer surrounds each insulating layer. An elastomeric jacket is extruded over and preferably bonded to each fabric layer. The jacket has flocked fibers to allow gas desorption while pulling the cable to the surface.Type: GrantFiled: May 28, 1985Date of Patent: April 14, 1987Assignee: Hughes Tool CompanyInventors: Raymond L. Guzy, Thomson H. Wallace

Patent number: 4589492Abstract: A submersible pump installation for a subsea well has an electrical connection that is hydraulically made up with provisions to avoid contact with sea water. The submersible pump is suspended by a suspension head located in a tubular member at the subsea wellhead. An electrical insulator is movably carried in a passage extending through a wall of the tubular member. An electrical connector pin is carried in the insulator. A piston moves the insulator into contact with the suspension head, then the connector pin into engagement with the electrical connector located in the suspension head. A seal and dielectric fluid in the suspension head serve to prevent contamination by liquids in the subsea wellhead.Type: GrantFiled: October 10, 1984Date of Patent: May 20, 1986Assignee: Hughes Tool CompanyInventors: Tom D. Greiner, Raymond L. Guzy, Dick L. Knox

Patent number: 4472598Abstract: An electrical cable has features that allow its use in wells containing oil, water and gas, for use with submersible pumps. The cable has a number of conductors. Each conductor is surrounded by an insulating layer of oil and brine resistant thermosetting material. The insulating layer is permeable to gas. A polymeric jacket is extruded around all of the conductors, separating the conductors from each other and in direct physical contact with the insulating layers. Perforations are placed in the jacket at regular intervals. During rapid depressurization, gas absorbed in the insulating layers is able to flow freely from the cable by means of the perforations in the jacket. The jacket has sufficient strength to prevent rupturing of the insulating layers during depressurization.Type: GrantFiled: April 27, 1983Date of Patent: September 18, 1984Assignee: Hughes Tool CompanyInventors: Clinton A. Boyd, Raymond L. Guzy

Patent number: 4430472Abstract: An elastomeric composition of the type used as a jacketing material for electrical wires and cables is shown having improved chemical, water and heat resistance. An ethylene/acrylic elastomer comprising a terpolymer of ethylene, methyl acrylate, and a cure site monomer is used as the base polymer and has blended therewith a polybutadiene. The polybutadiene has greater than 50% 1,2 polymerized units and has a molecular weight between about 1,500 and 25,000 grams/mole.Type: GrantFiled: December 17, 1982Date of Patent: February 7, 1984Assignee: Hughes Tool CompanyInventor: Raymond L. Guzy

Patent number: 4370518Abstract: A cable splice joining insulated conductor ends wherein the conductors are coated with lead, lead-tin alloy or tin, said splice comprising a metallic sleeve member joining the conductor ends, a first layer of adhesive over the sleeve member and any exposed conductor areas, a layer of foil formed of lead or lead-tin alloy covering the first adhesive layer, a second adhesive layer covering said layer of foil and extending over the exposed insulation; a helically-wrapped insulation layer formed of a thermosetting polymer, an over-lapped layer of fabric surrounding the insulation layer, a helically-wrapped heat-shrinkable type layer surrounding the fabric layer, and a heat-shrinkable sleeve surrounding the splice area, and a method for forming said cable splice, for providing cable splices which resist depressurization failure and corrosion of conductors when employed in high pressure gassy oil wells containing corrosive well fluids.Type: GrantFiled: July 27, 1981Date of Patent: January 25, 1983Assignee: Hughes Tool CompanyInventor: Raymond L. Guzy

Patent number: 4032270Abstract: A rotary sliding vane compressor having means for biasing the vanes outwardly. Such means include a resilient element located in the lower portion of the vane slot and engaging a convexly shaped edge on the vane. An improved wear surface on the resilient element at the area of contact with the vane slot provides enhanced service life. The flexing action of the resilient member ensures that the vanes will be moved outwardly during the expansion phase of rotor travel.Type: GrantFiled: May 28, 1976Date of Patent: June 28, 1977Assignee: Borg-Warner CorporationInventors: Rajesh N. Sheth, Raymond L. Guzy
