  • Patent number: 6112395
    Abstract: A process is disclosed for making fine metallic fibers comprising forming a continuous tube about a plurality of coated metallic wires for providing a first cladding. The first cladding is drawn for reducing the outer diameter and for diffusion welding the coating within the cladding. The tube is mechanically removed to provide a first remainder. The first remainder is drawn for reducing the diameter thereof to transform the plurality of metallic wires into a plurality of fine metallic fibers. In one example, the diffusion welded coating is removed for providing the plurality of fine metallic fibers. In another example, a plurality of the first remainders are assembled and a continuous tube is formed about a the first remainders for providing a second cladding. The second cladding is drawn for reducing the outer diameter. The tube is mechanically removed to provide a second remainder.

  • Patent number: 5845394
    Abstract: In manufacturing a yoke for an elastic universal joint, the time required for each step is shortened and the automation of each step is made easy, and by the energy saving and high efficiency of the manufacturing work, a reduction in the cost is achieved. A metallic plate is subjected to working which can be done easily and within a short time by press work such as stamping work, deep drawing work and ironing work, to thereby make a yoke for an elastic universal joint. This can be accomplished because welding work and cutting work which require much working time and which are cumbersome to automate can be eliminated. Investment in facilities may be small.

  • Patent number: 5622612
    Abstract: A process is recited for plating elongated current collectors with indium. The current collectors have particular utility in alkaline electrochemical cells, particularly zinc/manganese dioxide alkaline cells containing "zero-added" mercury. The process of the invention involves electroplating conductive wire with indium and then drawing the plated wire to a lesser diameter. The drawn plated wire may then be cut to the desired lengths, typically in the shape of a nail, for use as current collectors within the alkaline cell.

  • Patent number: 5379507
    Abstract: A tank construction including an outer shell of steel material comprised of two half members welded together. The half members are formed by a deep drawing process. An inner shell of non-corrosive material is cast inside the outer shell by a rotational casting procedure with the external surface of the inner shell located adjacent the internal surface of the outer shell. The inner shell of non-corrosive material provides a substantially leak-fight liner for the outer shell to thus prevent contact between the contents of the tank and the outer shell. The rotational casting of the inner shell inside the outer shell is accomplished by charging the outer shell with a non-corrosive material and then subjecting the outer shell to a rotational casting movement while heat is applied to the outer shell. The outer shell serves as a mold for the inner shell wherein the mold (outer shell) becomes a permanent part of the completed tank.

  • Patent number: 5282306
    Abstract: The present invention relates to a process for preparing a printed can be draw-forming or draw-redraw-forming a preliminarily printed metal blank or laminate. By forming an original plate for printing by an image processing by a computer, a print image faithful to the original image can be manifested on the side wall portion of the can, and formation of an undesirable stripe pattern can be prevented. Furthermore, a print image excellent in the linearity can be displayed without an error on the draw-formed can in due consideration of the anisotropy owing to the plastic flow of the blank.

  • Patent number: 4999901
    Abstract: The invention provides a process of producing a nozzle member for sucking and transporting a string of yarn having an inner diameter which varies along an axial direction of the nozzle member. The process comprises the step of drawing a pipe stock having a predetermined outside profile so as to transfer the outside profile in an axial symmetrical relationship to an inside profile of the pipe stock. By the process, a nozzle member can be produced readily with a high degree of accuracy.

  • Patent number: 4999903
    Abstract: A process for producing multi-layer composite tubes involves extruding an inner plastic tube prior to forming a metallic tube around the inner plastic tube which is subsequently covered with an outer plastic layer. The metallic tube is initially formed to have an inner diameter which is substantially greater than the outer diameter of the inner plastic tube. Subsequent to welding to seal the metallic sheet into the form of a tube, the excess diameter of the metallic tube is reduced in a manner which avoids stretching or elongating the tube. Adhesive coatings can be applied between the various constituent layers of tubes, and a mesh can be interposed between the metallic tube and the outer plastic layer.

  • Patent number: 4637117
    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.
