  • Expansion wedge for use with heat exchanger tube, and structure for mounting tubes to header member of the heat exchange
    Patent number: 6843097
    Abstract: An expansion section for expanding the distance between longitudinal side surfaces of an opening of a tube when being inserted a predetermined depth into the opening is formed an expansion wedge body, and guide protuberances are protrusively formed on the respective longitudinal sides of the expansion section. The guide protuberances are inserted into the spaces provided on the respective sides of the opening of the tube, thereby guiding the expansion section into the opening.
    Type: Grant

  • Structure for mounting tubes to header member of a heat exchanger
    Patent number: 6572153
    Abstract: A structure for mounting a tube to a header member of heat exchanger is such that the header member has a tube hole and the tube is disposed through the tube hole so that a portion of the tube projects out of and beyond the header member. The portion of the tube which projects outwardly is expanded via the insertion of an expansion wedge to establish a tight contact between the tube and the tube hole.

  • Production of biaxially drawn film of polyamide blend
    Patent number: 4098860
    Abstract: A process for preparing a biaxially stretched film of polyamide blend, which comprises (1) extruding a polyamide blend in melt to make an unstretched film and (2) stretching the unstretched film first in a machine direction with a stretch speed of about 40,000 to 60,000,000 %/minute in a draw ratio of about 2 to 6 and then in a transverse direction with a stretch speed of about 500 to 100,000 %/minute in a draw ratio of about 2 to 6, or (2') stretching the unstretched film first to make a uniaxially stretched film having a plane orientation index of about 0.6 to 1.
