  • Patent number: 5075176
    Abstract: In order to reduce the plug-in and tensile pulling forces of an electrical connector pair, the coating on the plug element of a socket and plug connector pair is given greater hardness than that for the other plug element. To this end, the base material (e.g., of a male plug) is given a surface coating of an alloy applied using the molten method. Besides tin and possibly lead (as well as small amounts of deoxidization and processing additives), this alloy also contains up to a total of 10% by weight of at least one element selected from the group consisting of silver, aluminum, silicon, copper, magnesium, iron, nickel, manganese, zinc, zirconium, antimony, rhodium, palladium and platinum. The melting point of the coating material preferably does not exceed 320.degree. C.

  • Patent number: 4874644
    Abstract: The invention relates to a material (504), having adjacent regions of differing strength and ductility, that has been formed by rapidly deforming a suitable base metal (501) having a banded structure, such as illustartively a previously cold worked low carbon steel alloy, in order to generate a high rate of change in the internal energy of the base metal. This energy change depressed the transformation temperatures of the base metal and induced an allotropic phase transformation to occur therein. Specifically, prior to being deformed, the base metal is maintained at a fairly low temperature, e.g. at or near room temperature. The tooling, preferably rolls, that is used to provide the deformation is maintained at a modestly elevated temperature.

  • Patent number: 4647511
    Abstract: Produced flake like metal chip has a shape being convexed in one side and concaved in the other side in its cross section.These metal chips are produced by dipping spherical or cone shaped projections provided on an outer surface of a rotary drum into molten metal contained in a molten metal reservoir, the molten metal adheres to each projections being dipped then the adhered molten metal is stripped off of each projection after at least a part of the molten metal has solidified.The apparatus for working the above-mentioned method includes, a molten metal reservoir, a rotary drum carrying on its outer surface a number of aforesaid projections, to the tip end of which the molten metal is adhered, and a means for stripping off the adhered molten metal after at least a part of the adhered molten metal has solidified.
