Title: Improvements in or relating to transmitters for electromagnetic communication systems
Inventor: SNEATH OSWALD BARBER
IPC: H04B5/04
Filed: 1956-12-18
Abstract: 850,526. Electric selective signalling systems. MULTITONE ELECTRIC CO. Ltd. Dec. 12, : 1957 [Dec. 18, 1956], No. 38607/56. Class 40 (1). [Also in Group XL<SP>2</SP>(c)]  In a transmitter for electromagnetic communication systems whereby individuals can be selectively called by transmitting signals on a correspondingly selected frequency within the audio and intermediate frequency range, the transmitter is provided with eight keys of the press button type in which a key pressed remains down until further keys are pressed but the call is terminated automatically by a timing circuit. The frequencies are selected by  pressing either one or two of the eight keys; making a total of 36 possible calling frequencies. A frequency range is selected by the highest numbered key pressed, and the frequency within that range by the remaining key. As shown, with the keys controlling contacts 2A to 2D and 5A to 5D pressed, contact 5A selects tap T5 on inductor L1, which is tuned by capacitors Cl, C2, to determined the frequency range. The frequency within the range is determined by shunting the part of the main inductance L1 with an inductance L2 preferably of higher value and for this purpose a lead 1 from a tap T4 or T5 on the inductor L1, which tap is selected according to whether the. higher number key pressed is greater or not greater than 4, is connected to the moving contact 1C of key number 1. The lower number key pressed selects the tap on inductor L2 which is connected to the inductor L1 via the lead 1. The change-over of the tapping point on L1 at which L2 is connected is arranged so that the percentage gap between adjacent frequencies at the higher frequencies may be lower. The higher number key pressed may also connect in one of the capacitors C5 to C12 in order to tune the output loop. In an alternative arrangement the lower number key pressed changes the capacity across L1 instead of shunting it with an auxiliary inductance.
