Abstract
1,081,086. Moulding electrically conductive material. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 10, 1964 [June 13, 1963], No. 23693/63. Heading B5A. [Also in Division F3] In a press for compacting an electrically conductive composition, e.g. an initiator or an igniter filling composition the movement of the ram is controlled by a servo system which is responsive to the electrical resistance of the compact being pressed, whereby the pressing is terminated when the resistance reaches a predetermined value. The servo system includes a comparator which compares the resistance of the compact with a reference resistance and the output of which is fed to an amplifier which controls an electric motor which operates the press. A tachometer driven by the motor provides a stabilizing feedback signal to the amplifier.
