Filed: 1928-04-04
Abstract: 304,523. Thorp, F., and Parkinson & Cowan (Gas Meters), Ltd. April 4, 1928. Coin action, mechanical-connection.-In a prepayment mechanism, such as used on gas and like meters, the coin is inserted through a slot in the usual price-change disc b, Figs. 1 and 2, into a holder f on a rotary slot closing plate g rotatable by a handle e. The cheeks of the holder are connected at the top and bottom by strips j and the gap i between them is bridged at the middle by a lug k on a member m pivoted, by a pin n passing through an elongated slot o, to the spindle h of the handle e. When a coin is inserted, an inclined edge of a slot in a plate d forces the coin against the lugs k, during the first rotary movement of the holder. The member m has a tooth p to engage a toothed quantity wheel g and is connected by a spring q<1> to the plate g. A hook or catch s projecting from the price-change disc engages a slot t in the member m and prevents the tooth p from engaging the wheel g, so that the lower end of the member m is moved outwards against the pull of the spring g<1> as shown in Fig. 6. When the member m clears the catch s, it is turned by the spring g<1> about the part k so that the tooth p snaps into engagement with the wheel g. In a. modification, Fig. 9, the member m is in two parts m, m<1> pivoted together at v, the part m having the projection k, while the part m<1> is connected to the spring q<1> and is engaged by the catch s.

Title: Signalling system
IPC: H04Q3/545
Filed: 1973-03-06
Abstract: 1420262 Automatic exchange systems; pulse discriminating circuits INTERNATIONAL STANDARD ELECTRIC CORP 6 Mareh 1973 [6 March 1972] 10719/73 Headings H4K and H3T A dial pulse receiver includes two capacitive timing circuits which time pulses and interpulse gaps respectively and respectively set and reset a common bi-stable element in response to signals of at least a given duration. The figure shows a dial pulse receiver suitable for use in a program controlled exchange of the type described in Specification 1,181,182. When the exchange control unit CO detects an off-hook subscriber station a selected receiver is coupled to that line via the switching network and relay Er is enabled to close contacts e 1 , e 2 . The transformer W 1 , W 2  is used to couple dial tone to the line. Capacitors C 1  and C 2  are in the stand-by state charged via R13, R14 and R15 to a -27À7 volt level set by a potential divider R8 to R11 and a conducting diode d3. Transistor T 2  conducts and transistor T 1  is blocked at this time. When the subscribers loop is completed T 1  turns on discharging C1 via R12 to negative battery causing d3 and d4 to be immediately blocked and allowing if the loop break persists for 16 milliseconds the capacitor C 2  to discharge mainly via R16 to a level -31À7 volts set by d5 (now conducting) and potentiometer R8 to R11, transistor T 2  being arranged to be blocked at -31À4 volts, i.e. after 10 milliseconds of this time During each loop break (dial pulse) T 1  is immediately blocked, T 2  becomes conductive 10 milliseconds later and after 16 milliseconds both capacitors are charged to -27À7 volts. Thus provided each loop and loop-break lasts 16 milliseconds they are repeated at the output of transistor T 2  with a delay of 10 milliseconds. If they have a duration of less than 10 milliseconds they are not repeated and if they have a duration between 10 and 16 milliseconds are repeated with a smaller delay. If due to a faulty connection mains signals are supplied to the transformer, transistor T1 conducts for each positive half cycle and the consequential large current causes diode d6 to be blocked. Transistor T2 conducts and such pulses are counted at CR which operates an alarm after 15 such pulses.
