Title: Improvements in or relating to Methods of Converting Pulse Trains
IPC: H04M17/02
Filed: 1968-09-27
Abstract: 1,197,532. Automatic exchange systems. SIEMENS A.G. 27 Sept., 1968 [29 Sept., 1967], No. 45883/68. Heading H4K Metering pulses arriving at a prepayment substation are utilized to step a first uniselector whose contacts are so connected to those of a second uniselector that the latter is caused to step thereby a variable number of times whereby the values represented by the positions of the two uniselectors are kept as closely aligned as possible. In the German system described each metering pulse corresponds to a charge unit of 18 pfennig and each coin pulse to a value of 10 pfennig which is the minimum value coin acceptable by the coin box. If the same metering pulse rate is to be used for all subscribers it is therefore necessary to convert each metering pulse into a number of coin pulses each of which represents 10 pfennig. If this number is the same for each metering pulse then obviously a vast discrepancy between the required call fee and the actual fee paid would arise. Reference is made to a prior art method of solving this problem using capacitors. In the present embodiment the interrelated stepping of the uniselectors ensures that the discrepancy remains small and in fact vanishes altogether once every 5 metering pulses. Particular description.-An arriving metering pulse brings up relay J thus closing the operating circuits for selector magnets D1, D2. Wiper da1 of the first uniselector thus steps to and stops on the first outlet 1. Wiper da2 however on reaching its first outlet finds earth potential thereon and its magnet is thus enabled so as to step da2 to outlet 2 where it stops. Relay C operates at each step of da2 so as to produce a coin pulse. Receipt of the next metering pulse steps da1 to outlet 2 and da2 to outlet 4, and the following pulse sets da1 on its outlet 3 and da2 on its outlet 5. The fourth pulse steps da1 to outlet 4 and da2 to outlet 7. The fifth pulse causes wiper da1 to reach outlet 5 whereby this switch then homes by virtue of its self-interrupter contact d1. The fifth pulse also causes wiper da2 to reach outlet 9 whereby this switch then homes without producing any more coin pulses. This sequence repeats with the arrival of further metering pulses. The first switch thus counts in steps of 18 pfennig while the second switch counts in steps of 10 pfennig with the second switch being set to a value, which is an integral multiple of 10, normally higher than that to which the first switch is set but which is the same at each fifth step of the first switch.

Panels 128 indicate the connections to the mode. Connector 36 is releasably held between a spring 50, Fig. 2, and the tips 64, 66 of the combs 56, 58. To insert a connector 36, arms 80, 82, Fig. 1, of levers below the apparatus frame are squeezed together which pushes combs 56, 58 outwardly on pins 70, 72 against the resilience of springs 76 on pins 70, and when a connector 36 has been placed in position, arms 80, 82 are released and springs 76 urge combs 56, 58 against the connector to grip it.

Abstract: 1,100,192. Electric control circuits. EATOUGHS Ltd. 9 Sept., 1964 [27 Nov., 1963], No. 46910/63. Heading G4H. A machine control mechanism comprises a search uniselector connected with a bank of individual switches A each when operated causing the search uniselector to move to a different position, a second uniselector connected with the first and serving as a pulse counter being advanced by pulses generated from the machine and adapted to stop the machine when its position corresponds with that of the search uniselector. The apparatus is described applied to a conveyer having 48 work stations arranged on either side in 24 pairs. These positions are termed " odd " and " even ". The search uniselector has 24 positions. A work station may call for work by closing a switch Cl and a corresponding lamp L1 lights at the control unit. The operator then presses a corresponding button to close one of 24 switches A and one of 48 switches B. The search uniselector moves to the corresponding position and one of relays 1A or 1B picks according as to whether the switch B operated was odd or even. If the position reached by the search uniselector corresponds to the station calling for work the relay 1A or 1B is latched through the contact C 1  enabling the conveyer to begin moving. As it moves cam-controlled contacts make a pulse for each station position and these are applied to step the second uniselector. When it reaches the position of the search uniselector, one of relays 3A or 3B will pick and the conveyer will stop. While the conveyer is taking work to the work station a lamp L2 is lit. This goes out when the conveyer stops at that station.
