Title: System of charging subscribers and for the remote reading of telephone charges
IPC: H04M15/04
Filed: 1963-12-09
Abstract: 1,055,450. Automatic exchange systems. J. C. LAVENIR. Dec. 9, 1963 [Dec. 7, 1962], No. 48514/63. Heading H4K. In a cross-bar system in which metering is effected at the links between a non-numerical subscriber switching stage and the first numerical switching stage, the identity of a subscriber utilizing a particular link and the metering pulses occurring on this link during a call are recorded in a temporary store associated with this link and at the end of the call the temporarily stored metering information is transferred to a semi-permanent store associated with this subscriber which contains the cumulative charge for calls made by the subscriber. The system is particularly applicable to the case where a concentrator serves to connect a group of remote subscribers to a central exchange. The stores comprise tracks on a continuously driven magnetic drum in which information is stored in serial form. General operation of the system.-A calling subscriber is connected via a non-numerical switching stage in the concentrator to a free link extending to the first selection stage in the central exchange. The links are scanned sequentially by means of a scanner operating in synchronism with a magnetic drum whereby the identity of the calling subscriber, which is determined from the markings on a marking multiple extending between the concentrator and the exchange, is stored in binary form in a transit store and transferred to the compartment of the magnetic drum associated with this link. The private and marking wires of a link are monitored during each scan and their condition, i.e. busy or free, and metering pulse present or absent, respectively, is transferred via the transit store to the relevant drum compartment. At the end of the call, link scanning is stopped, and the metering charge, stored in the link compartment of the drum, is added to the charge for previous calls stored in the relevant subscriber's compartment of the drum by means of an adding circuit associated with the transit store. The transfer of information between the link and the drum is controlled by means of a " programmer " which initiates a different sequence of operations in response to the following conditions, (i) initiation of a call (receiver lifted, private wire of link just marked), (ii) initiation of a metering pulse, (iii) end of a metering pulse, (iv) end of call and (v) ticketing. The last condition arises when the telephone accounts department marks a special input of the programmer whereby link scanning is stopped and the metering information in respect of each of the subscribers is destructively read-out from the drum and is passed via the transit store to the accounts department.

Title: Improvements in or relating to Function Generators.
Inventor: LEWIS LEON DAVID
IPC: G06G7/28
Filed: 1967-11-01
Abstract: 1,185,390. Function generators. ULTRA ELECTRONICS Ltd. 1 Nov., 1968 [1 Nov., 1967], No. 49548/67. Heading G4G. [Also in Division G3] A precursive linear function generator (Fig. 1) comprises six inverting amplifiers 1 to 6 connected over series diodes 7, 8, 9 to point 39, which is negatively biased over resistance 40 and connected to output 13 over diode 42 positively biased over resistance 44. Output 13 supplies feedback over resistors 24 to 25 to the first input of corresponding amplifiers. The second input of amplifier 1 receives voltage V 1  over resistors 27, 28, the first input of amplifier 2 receives feedback bias + Vb, over resistors 30, 31, and input voltage -V F  over resistance 32, and the second input of amplifier 2 is earthed over resistance 33. Similar arrangements apply input - V F  and bias Vb 2  to amplifier 3. Similarly arranged amplifiers 4, 5, 6 receive feedback from output 13 to first inputs and those of amplifiers 5, 6 phase inverted input signals over amplifier 49. The second inputs respectively receive signal + V 2  and bias voltages Vb 3 , Vb 4  over series resistances. Operationally, for zero input, signal V 1  is amplified at 1 and applied to output 13, with feedback to the remaining amplifiers exceeding their respective inputs. As - VF increases negatively to exceed Vb 1 , amplifier 2 output exceeds that of amplifier 1 until input exceeds Vb 2 , when amplifier 3 output exceeds that of amplifier 2 (segment C). At equality of output with signal V 2 , amplifier 4 supplies output 13 (segment D) until inverted input exceeds Vb 3 , when amplifier 5 output exceeds that of amplifier 4 (segment E). Similarly, when inverted input exceeds Vb 4 , amplifier 6 output exceeds that of amplifier 5 (segment G) so that a desired voltage function of input variation is developed at 13 (Fig. 3). In a modification (Fig. 2, not shown), diodes 11, 12 are reversed and a further diode is connected between the combined outputs of amplifiers 5, 6 and output 13, with applied negative bias to the diode function and bias Vb 5  replacing Vb 4  on amplifier 6. Then the function segment E changes to segment F when the input signal reaches equality with Vb 5 . The amplifiers may be solid state integrated circuits incorporating then film resistors on the same substrate, and the device may be arranged as an integrated circuit. The output may be non-linear. Preferred component values are specified. The device is stated to be modifiable to incorporate pneumatic or hydraulic amplification and logic.
