Abstract

396,819. Impulse transmitters. SIEMENS & HALSKE AKT.-GES., Wernerwerk, Siemensstadt, Berlin. Feb. 17, 1932, No. 4748. Convention date, Feb. 20, 1931. [Class 40 (iv).] In an impulse transmitter of the type in which a complete number is transmitted as the result of a single selecting operation, the impulse-transmitting discs 1 are provided at their peripheries with detachable and interchangeable digit-determining means such as screw pins 8 or toothed segments with different numbers of teeth. The appropriate disc is selected by a key 4 which moves contacts 5 rotatably mounted at 6 into operative engagement with the disc.
