Filed: 1952-10-11
Abstract: 707,311. Intercommunication systems. ADLER, A. E. Oct. 6, 1952 [Oct. 11, 1951], No. 23751/51. Class 40 (4) In a system in which conversations between a number of different pairs of intercommunication stations may take place simultaneously over separate speech circuits, the telephone transmitters at the stations may be switched to a paging circuit comprising an amplifier 10 and a loudspeaker 11, lamps 16 being provided for indicating when the paging circuit is in use. Two stations forming part of an intercommunication system are shown, each station comprising a receiver 17 and a transmitter 18 which may be combined in a handset. Calling between stations is effected by a push button 28 which in an overthrow position contacts a ringing bar 36 and completes a circuit from a ringing battery 13 to a buzzer 32 over the home line 30 or 31 of the station required. When an operated button is released it remains mechanically locked against a speaking bar 35 until the handset is replaced, thereby maintaining the speech circuit, which extends over a condenser 34 and the operated switch-hook contacts SH. A pair of common return leads are provided which are connected to the receiver and transmitter at each station over a resistor bridge circuit 21 as described in Specification 650,070. To transfer a transmitter to the paging circuit, a switch K is operated so that a relay R is pulled up by a paging speech battery 14. Operation of relay R removes a disabling short-circuit from the amplifier at contact R46 and completes a busy circuit at contact R47 from battery 15 to the lamps 16, the lamp at the calling station being isolated by switch K. Speech currents to the amplifier are induced in a second relay winding 44 from the operating winding 41. In order to compensate for voltage drop in the lamp circuit, the common lead is connected at each station to one side or the other of a fixed resistor 50. According to the Specification, the switch K may alternatively connect the receiver and transmitter of a station to a loud-speaking master station over a three-wire circuit.
