  • Patent number: 5826410
    Abstract: The tool 10 of the present invention includes in its mid-portion a handle or gripping portion 12. Extending outwardly in opposite directions from the gripping portion are a pair of spaced transition portions 14 and 16 each respectively terminating in a pair of tapered portions 18 and 19. The tapered portions 18 and 19 extend to a box engagement portion at each end 20 and 22. Each box engagement portion includes a transversely extending tapered portion 24 and 26 each of which terminates in a respective edge 28 and 29, and respective hook portions 30 and 32. It will be apparent that the transverse portion 20 is smaller than the transverse portion 22 to allow opening of smaller boxes with the end where transverse portion 20 is located.

  • Patent number: 5600990
    Abstract: A steel extrusion apparatus is shown having an improved die stack with a direct cone geometry. The die stack includes a die holder with removable and replaceable die inserts. The die inserts are made from a high strength material while the die holder is made of a less expensive, traditional material. A hot metal billet is extruded through an orifice provided in the die insert of the die holder. The die stack assembly is retained as an assembled unit as the extrusion container is moved out of contact with the assembly and the butt end of the metal billet is discarded. The die stack assembly is then again located on the extrusion container as a unit to begin another extrusion cycle.

  • Patent number: 5598735
    Abstract: A method of manufacture of a hollow stabilizer for automobiles which uses a heat-finished seamless steel pipe 20 as a material, comprising an inner surface and/or an outer surface of a part corresponding to a bending R portion A-B of the steel pipe 20 is polished to remove defects of the surface of the steel pipe, and after the above surface roughness is made less than Rmax 50 .mu.m, the part corresponding to the above bending R portion is previously formed an ellipse in section, and then the section after bending process accesses to a true circle to alleviate stress concentration of the bending part.

  • Patent number: 5590510
    Abstract: An ink tank cartridge is provided removably mountable onto an ink supply needle of the ink-jet type recording apparatus body. The cartridge has a housing provided with an ink supply port extending through and projecting from a wall of the housing and into the chamber of the housing. A porous member having ink impregnated thereon is positioned inside the chamber of the housing abutting against the ink supply port. A filter is mounted on the inner end opening of the ink supply port. The ink tank cartridge is further provided with a packing member for resiliently abutting against the outer periphery of the ink supply needle and is positioned adjacent one end of the ink supply port. The outer opening of the ink supply port is sealed with a sealing member through which the ink supply needle penetrates.
