Abstract:
A process for coating a machine part surface wherein the surface is cleaned, abraded and treated so as to render the surface directly bondable to a resin-bonded lubricant coating. A resin-bonded lubricant coating then is directly applied to the treated machine part surface and cured so as to cross-link the resin.
Abstract:
The present invention relates to a cooling fluid for metal cutting, drilling, grinding and other fabricating operations comprising a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3, --C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F., and an at least partially soluble acid.The present invention also relates to a process and fluid product made by a certain process for cooling tools and workpieces for metal cutting, drilling, grinding and other fabricating operations comprising the steps of mixing a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3,--C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F., and an at least partially soluble acid, the mixture being a cooling fluid, maintaining substantial contact between the cooling fluid and an amount of transition metal or alloy containing at least one transition metal, sufficient to catalyze a reaction within the fluids during fabrication, and operating a tool while maintaining substantial contact between the tool and the fluid during fabrication.
Abstract:
Lubricant system for sheet and section rolling mills, containing a solid lubricant, an adhesive component and/or a thickening agent, and also water as a carrier medium. The lubricant system is sprayed onto the working cylinder in the roll stand as a suspension, at least some of the water evaporating and a firmly adhering, waterproof, lubricating and separating film forming on the working cylinders.
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.
