Title: Supervisory signalling system for toll telephone service timing
IPC: H04M3/12
Filed: 1928-12-27
Abstract: 303,116. Onishi, H. Dec. 28, 1927, [Convention date). Time indicators.-A timing arrangement for toll calls comprises lamp or other signals controlled by a three-wiper rotary step-by-step switch the movement of which is initiated by the operator and then continued automatically until the time period has elapsed. If the call ends before the time period, the operator may cause the switch to be driven rapidly to normal. At the commencement of a conversation, operator throws key K to close contacts l, n whereby ground from a six-second interrupter F is connected over magnet I to battery VI. The magnet D drives wipers A, B, C and after the first step the driving circuit is maintained over wiper C independently of contact n, and a circuit is completed for lamp W over wiper A. Lamp W glows steadily during the first 24 steps (2¢ minutes) after which the circuit is transferred to a red lamp R for a further 4 steps (24 seconds), and at the last step the lamp R is flickered over wiper B and interrupter IR. If the conversation is to continue key K is held operated, If the call ends when the wipers are in an intermediate position, operator throws key for relay R1 and magnet D in series over wiper K to close contact m which completes a circuit C. The magnet does not operate but R1 closes a circuit at S1 for R2 which at S2 short-circuits R1 and operates the magnet. The wipers are thus stepped to normal. In a modification, the relays R1, R2 are replaced by a polarized relay operated by alternating current. If a call is interrupted by the occurrence of a fault, the operator restores key K until the fault has been remedied. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the interrupter IR is dispensed with, in which case the contact strip w of wiper A is extended so that lamp R glows for a further six seconds. This subject-matter does not appear in the Specification as accepted.

Each plotted curve is provided with one or two horizontal calibration lines, plotted with the same D. C. voltages applied as for the associated curve. The sampling converter has a sampling switch 7 driven by the output signal of a comparator 9, to supply an RC analogue store 19 which provides a "y" - deflection voltage, Uys to the recorder at 17. A time base generator 12 supplies an "x" - deflection voltage Uxs to the recorder at 14. D.C. voltages from an "x" auxiliary voltage generator 15 and a controllable staircase voltage generator 20 are added to the "x" - deflection and "y" - deflection voltages respectively by "x" mixer 13 and "y" mixer 18. The comparator 9 also controls a pen-lift voltage UL to the recorder. The comparator inputs are the time base generator 12 output and an output U@w at 8 representing the x-deflection voltage of the c.r.t.
