Abstract
593,171. Making electric contacts ; riveting. IGRANIC ELECTRIC CO., Ltd. June 11, 1945, No. 14728. Convention date, June 10, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Groups II, XXV and XXXVII] Powder metallurgy; working at specified temperatures.-Powdered materials such as those described in Specification 588,652 are densified by pressure at 10,000/40,000 1bs./sq. inch and sintered at 1600‹ F. to form a contact element 28, which is then riveted to an apertured plate 25 by moulding at 100,000 1bs. /sq. inch, which operation may be cold, but is preferably at 400‹ F. The element 28 is placed in a hole 26 in the plate 25, which is located in a recess in the moulding-die part 29, and the element then compressed between the die-punch 32 and pad 36, so as to form a contact 35. In modifications, Figs. 4-17 (not shown), the hole 26 may be threaded or countersunk, and the element 28 may be formed with a head. In Fig. 19, a headed element is non-rotatably mounted on a support 56, the head being compressed into the off-set portion 56c and the shank to overlie the edges 56d, 56e.
