Patent GB-888201-A (GB)
Title: Improvements in or relating to terminal or repeater equipment for electric communication systems
IPC: H04B3/10
Filed: 1959-08-14
Abstract: 888,201. Automatic volume control. GENERAL ELECTRIC CO. Ltd., and HARROLD, A. E. Aug. 11, 1960 [Aug. 14, 1959], No. 27868/59. Class 40 (4). Pilot control apparatus for terminal or repeater equipment includes a movable contact the position of which varies in accordance with variation of a control signal whose value is dependent on the level of a pilot current, the movable contact, during failure of the pilot current, being held in contact with a potentiometer which provides a stand-by signal having substantially the value that the first control signal had immediately prior to failure of the pilot current. Modulated carrier signals and a pilot signal applied to input terminal 1 pass through a regulator 3, which controls their values, to output terminal 2. The pilot signal is separated by a filter 4, passed through an amplifier 5 and detector 6 and in a comparator 7 compared with a standard signal from a terminal 8. It is also applied to a relay R1. Comparator 7 provides an error signal that is supplied through a winding 9 to the regulator 3 for varying the level of the modulated carrier signals. Winding 9 is part of a measuring instrument 10 and controls the deflection of pointer 11. In the event of failure of the pilot R signal, relay R1 reverses contacts - from the 1 position shown and an electromagnet (not shown) is energized to displace pointer 11 to form a connection between a point on a fixed contact 13 and a point on a potentiometer winding 14 until the pilot signal is restored. A voltage across winding 14 is such that the voltage supplied to fixed contact 13 is the same as that which the control signal had immediately prior to failure of the pilot current. This voltage is supplied by contacts R/1 to regulator 3.   If the level of the pilot signal falls slowly, relay R1 operates when the pilot signal falls to a predetermined value and the alternative control signal has a level corresponding with this value.

In an output operation a register normally used for other purposes is put into a loop circuit through which the output word is passed, transmission to output equipment being effected simultaneously and the end of the word being indicated without the insertion of an additional signal. A word to be transmitted is stored in memory MEM, an input/output register I/O R is cleared and a counter M/Q count normally used for storing a multiplier or quotient is put into the loop. Excess-3 code is used but 0000 indicates S or the end of a word. Initially therefore the register I/O R stores S. As each digit is sent from I/O R to M/Q count it is also sent to input/output equipment I/O M. Therefore when the signal S completes a circuit it indicates the end of a word.
