  • Aqueous machining fluid and method
    Patent number: 5874390
    Abstract: An aqueous machining fluid admixture comprises water, a sulfurized oil and a water soluble salt of a dimercaptothiadiazole wherein the weight ratio of the sulfurized oil to the water soluble salt of dimercaptothiadiazole is in the range of from about 15:1 to about 45:1. A method employs the fluid by applying the fluid at the interface between tool and workpiece in shaping or working operations of metallic and solid non-metallic workpieces. The fluid is particularly effective in grinding operations to produce improved grinding ratios.

  • Metalworking process
    Patent number: 5706684
    Abstract: There is provided a metalworking process, such as for example a punching process, wherein a shaping tool (eg. punch) contacts and applies a non-chip forming shaping force to a metallic workpiece (eg. blank) and there is supplied to the interface between the shaping tool and the metallic workpiece an aqueous fluid composition, having an alkaline pH, comprising water, a tall oil fatty acid, sulfurized lard oil, a sulfurized olefin, an oxyethylene/oxypropylene random or block copolymer diol having an average molecular weight in the range of from about 1000 to 8000 and an organic phosphate ester such as for example poly (1,2-ethanediyl) alpha-isodecyl-omega hydroxy phosphate. Reduced forces, lower friction and improved tool life are observed.

  • Method of making pull tabs and lubricant therefor
    Patent number: 5667349
    Abstract: An improved process for making metallic pull tabs is provided. In accordance with the improved pull tab making process comprising the steps of feeding a strip of metal into a pull tab forming die and forming the metallic pull tab the step of forming the pull tab is carried out in the presence of an aqueous based lubricant composition comprising water, an alkaline pH producing substance selected from the group consisting of alkali metal hydroxides, water soluble or dispersible aliphatic amines and water soluble or dispersible hydroxyl substituted aliphatic amines, an emulsifier, a water soluble or dispersible alpha (p-nonylphenyl) omega hydroxypoly (oxyethylene) phosphate ester and a water soluble or dispersible aliphatic diol.
