Abstract: A coupling for joining a downhole pump to a sucker rod string is disclosed. The coupling includes a core having a first end, a central portion, and a second end. The first end and the second end each have an end surface. The first end tapers linearly inwards from the central portion to the first end surface. The second end has a rounded edge along the second end surface. The coupling is made from a spinodally-hardened copper-nickel-tin alloy and has a sliding coefficient of friction of less than 0.4 when measured against carbon steel.

Abstract: An electrically conductive wire for deep water transmission includes a first wire portion and a second wire portion. The first wire portion makes up one end of the wire, and is formed from a first metal. The second wire portion is formed from a second metal. The first metal has a higher ultimate tensile strength than the second metal. The first wire portion is used to support the weight of the second wire portion, thereby allowing the electrically conductive wire to be used in underwater or subsea power cables which may be freely suspended from their origin for providing electricity to electrical devices located in deep water or ultra-deep water.

Abstract: A spinodal copper-nickel-tin-manganese alloy is disclosed that contains from 0.001 to about 2 weight percent phosphorus. When combined with small hard particles, the alloy has sufficient fluidity to infiltrate and fill at least 90% of the interstices of the hard particles, resulting in a composite article having superior strength and toughness. This composite article can be used in drilling bits and other cutting tools, either as a support body for cutting elements or as the cutting element itself.

Abstract: A mold for use in die casting aluminum parts is made from an underaged Ni—Be alloy containing about 1.0 to 2.0 wt. % Be.

Abstract: An unwrought continuous cast Cu—Ni—Sn spinodal alloy and a method for producing the same is disclosed. The Cu—Ni—Sn spinodal alloy is characterized by an absence of discontinuous &ggr;′ phase precipitate at the grain boundaries, ductile fracture behavior during tensile testing, high strength, excellent wear and corrosion resistance, superior bearing properties, and contains from about 8-16 wt. % nickel, from about 5-8 wt. % tin, and a remainder copper.

Abstract: A shot block for use in a die casting machine for die casting molten and semi-molten metal parts is formed from a metal or metal alloy having a thermal conductivity of at least about 25 Btu/ft.hr.° F., a Rockwell C hardness of at least about 25 and a 0.2% Yield Strength of at least about 90 ksi.

Abstract: A fluid powered drilling motor adapted for drilling oil wells and other subterranean bore holes. The motor having a rotor and a stator wherein the iron content of the whole motor is less than 0.1% wt. In one embodiment the motor is made of an alloy having a base metal comprising one of copper, nickel, and aluminum plus about 0.05-10 wt % Beryllium. In another embodiment, the motor is made of either 15Ni-8SN—Cu or 9Ni-6Sn—Cu.

Abstract: An improved thin walled threaded spacer for use in preventing thread galling in adjacent sections of drill pipe in a drill string is formed by mechanically deforming a strip of copper/beryllium alloy containing 2% beryllium to form a preform having a hollow, truncated conical section and then mechanically deforming the conical section to impart helical grooves therein.
