Abstract: A lubricant is provided to help in drawing containers such as cans from tinplate or coated tin free steel and to assist the metal forming process during drawing. The lubricant is formulated to permit a post spray without removal of the lubricant thereby eliminating washing and drying the container before post spraying. Post spray coatings are solvent or water based and are necessary to protect the container from the harmful effects of the material carried within the container and in turn to prevent contamination of the product by its container. A method of lubricating a metal to be deeply drawn into a sanitary can is explained and includes leaving the lubricant on the can during interior post coating operations.

Abstract: A radially-resilient seal can frequently pop out its annular groove defined in a carrier when the carrier and an overlapping housing are telescopically assembled. Such misorientation of the seal prevents proper seating of the seal against the housing and ultimately permits leakage of pressurized fluid past the seal.The present invention provides a compact sealed joint and fool-proof method of assembly which maintains proper orientation of a radially-resilient seal during telescopic assembly of a carrier and a housing. The sealed joint includes an annnular member having a diametrically tapered internal surface. The annular member positively ensures that the seal will properly seat against a housing inner surface which is not only physically inaccessible to the assembler but is also hidden from the assembler's view by an outer casing during the telescopic assembly.

Abstract: A tool for producing a pattern of highly accurate optical quality surfaces and the method of making same from a series of bi-metallic pins. A high strength metal pin is coupled to a slug of metal of lesser strength capable of being accurately scribed.
