Abstract: A flexible lubricant applicator for forcibly applying a desired quantity of a lubricant material (such as carbon particles usually of the graphite type, particles of the Teflon type, polytetrafluoroethylene material, or the functional equivalent) to a workpiece surface which is harder than the lubricant material and usually comprising a metallic workpiece surface.

Abstract: An improved mist lubrication process whereby excellent lubrication and misting properties are obtained utilizing synthetic ester mist lubricants derived from specific polyol esters, trimellitate esters and dimer diesters and a mixture of polyisobutylene polymers having different molecular weights is provided.

Abstract: The invention's application is suited in particular to the lubricated turning pairs of crawler tracks. It makes provision for the sealing of the lubricant reservoir by means of an elastomer plug, and for the introduction of a needle into and through the plug. The needle serves to effect evacuation of any existing air from within the reservoir, and the subsequent introduction of lubricating oil. The needle is then withdrawn from the plug which, by virtue of the elastic properties of the elastomer, automatically re-encloses the puncture produced by the needle.

Abstract: Hydrogenated 1,3-butadiene polymers are used as synthetic lubricants. The polymers of this invention range in molecular weight from about 150 to about 3,000 and are characterized by a 1,2 addition structure of at least about 60 percent.
