Abstract: A method for manufacturing a lubricating grease having improved properties is described. The method comprises reacting a pyrrolidone with a fatty amine and subsequently adding a metal hydroxide to the reaction when the unreacted fatty amine content ranges between about 33 and about 66 wt. % of the fatty amine originally added. The grease thus formed will be a NLGI #0 grade grease that has the high temperature stay-in-place properties of a NGLI #2 grade grease.

Abstract: A self-releasing choker has ferrule holding jaws in a casing movable between a ferrule accepting station, a load carrying station, and a ferrule releasing station located intermediate the other two stations. Locking means holds the jaws closed while in the load carrying station and releasing means permits the jaws to open only while they are moving past the ferrule releasing station in the direction of the ferrule accepting station. Dampening means provides a time delay to keep the jaws from moving all of the way to the ferrule releasing station when the load is only momentarily taken off the ferrule.

Abstract: A metalworking lubricant composition which is particularly effective in high-temperature forging operations comprising a major amount of a naphthenic base oil which includes at least about 20 weight % of reduced naphthenic crude oil and preferably a minor amount of an additive which is either a zinc dihydrocarbyl dithiophosphate or a selected sulfur containing compound.

Abstract: A coating composition useful in metal working processes comprises a major amount of a mineral oil having a viscosity of 100.degree.F of at least 100 SUS and (a) 1.0 to 20.0 parts by weight of a paraffin wax, (b) 0.1 to 10.0 parts by weight of a polymeric wax modifier and (c) 0.1 to 10.0 parts by weight of an extreme pressure agent. The compositions can also contain one or more rust inhibitors. Particularly preferred classes of extreme pressure agents for use in this comparison are sulfur containing agents and zinc salts of dialkyl dithiophosphates.
