The carbon composite comprises carbon and a binder containing one or more of the following: SiO2; Si; B; B2O3; a metal; or an alloy of the metal; and the metal comprises one or more of the following: aluminum; copper; titanium; nickel; tungsten; chromium; iron; manganese; zirconium; hafnium; vanadium; niobium; molybdenum; tin; bismuth; antimony; lead; cadmium; or selenium.
Abstract:
A system and method of processing an alloy ingot or other alloy workpiece to reduce thermal cracking and reduce friction between the workpiece and the forging die may generally comprise positioning a multi-layer pad between the workpiece and the forging die. An article for processing an alloy ingot or other alloy workpiece to reduce thermal cracking also is disclosed. The present disclosure also is directed to an alloy workpieces processed according to the methods described herein, and to articles of manufacture including or made from alloy workpieces made according to these methods.
Abstract:
Lubricating compositions for use in the casting of steel, in particular in continuous casting processes are provided. Methods for making and using such compositions are also provided.
Abstract:
Provided is a method for producing a seamless tube, in which after a starting material to be extruded has been heated to a heating temperature T [° C.] satisfying the relationship of Formula (1) or Formula (2) depending on the outside diameter d0 [mm] thereof, the starting material is hot extruded by providing a solid lubricating glass between the starting material to be extruded and a die, whereby a transverse flaw on the outer surface in the top portion of tube can be prevented when hot extrusion is performed by using a starting material for extrusion having low deformability at high temperatures. When d0
Abstract:
The disclosed invention provides a composition that possesses insulation values approaching that of uncompressed foam neoprene. The liquid composition is incompressible and may be formulated to be neutrally buoyant in water. The composition is suitable for a use in a number of applications where insulation is required, including divers' suits and underwater cabins, such as chambers, submersible hulls, and waterproof housings.

Abstract:
An environmentally friendly lubricant composition useful for well contains: between 40% and 80% by volume of unsaturated fatty acid(s) having between 16 and 26 carbon atoms and between one and three carboxylic acid moieties, or triglyceride(s) having from 16 to 26 carbon atoms and at least one double bond, or mixture thereof; at least about 20% by weight of a suspension agent which is a Group I and/or Group II metal salt or base that is reactable with a carboxylic acid moiety in the unsaturated fatty acid; a film-forming amine R1—N—(R)2 wherein the amine has between ten and thirty carbon atoms; or mixtures thereof, wherein the amount of suspension agent is sufficient to provide at least a 50% overbased composition; and between about 10 and about 50 pounds of a polymeric beads per barrel of lubricant composition, wherein said lubricant composition is blended to form a substantially homogenous composition.
Abstract:
This invention provides a non-asbestos friction material excellent not only in performance at the time of braking under high loading at high temperatures but also in performance at the time of braking under low loading at low temperatures even if lead sulfide is not used in the filler. In the non-asbestos type friction material comprising a non-asbestos fiber base material, a filler and a binder, the filler comprises spherical bronze powder and artificial graphite and is free of lead sulfide.
Abstract:
Silicone grease comprising (A) an amino-modified silicone fluid having an amine equivalent of 10,000 to 200,000 g/mol and a viscosity of 10 to 100,000 cs at 25.degree. C., and (B) a thickener exhibits improved heat resistance and low-temperature resistance.
Abstract:
The present invention includes a method for the manufacture of a bearing seal which includes providing a polymer and/or a filler coated with a polymer and thereafter heating the coated filler to bond the copolymer to the filler. Following cooling of the coated filler, it is pulverized and added to granular polytetrafluoroethylene. This admixture is then mixed to obtain a uniform blend and thereafter shaped by compacting and heating into a preselected form. Fillers suitable for the present invention may be carbon, metal, glass, carbide, disulfide, polymeric, polyester fluoride and ceramic fibers.
