Title: Improvements in semiconductor logic circuits
IPC: G06F7/501
Filed: 1960-12-09
Abstract: 964,897. Digital electronic calculating apparatus. RADIO CORPORATION OF AMERICA. Dec. 9, 1960 [Jan. 13, 1960], No. 42540/60. Heading G4A. [Also in Division H3] In an adder,the sum circuit comprises a negative resistance diode 86, e.g. a tunnel diode, connected in series in the base-emitter path of a transistor 92,and the carry circuit comprises a second negative resistance diode 108 in parallel with the base-emitter circuit of a second transistor 114. With no inputs, both diodes are in their low state and the outputs of both stages are logical 0. With one input the diodes are still in their low states and the output from the transistor 114 is still a logical 0 due to the shunting effect of the diode, the output from transistor 92 however is changed to a logical 1 due to the increase in baseemitter voltage. With two inputs the diode switch two their high state,thus most of the input to transistor 92 is dropped across the diode 86 and the output is again a logical 0, whereas the shunting effect of diode 108 is reduced and the output from transistor 114 become a logical 1. With three inputs the voltage across transistor 92 increase and both outputs become a logical 1.

Title: Automatic charging system
IPC: H04M15/04
Filed: 1970-09-09
Abstract: 1307557 Telephone metering systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 9 Sept 1970 [9 Sept 1969] 43253/70 Addition to 1233754 Heading H4K The metering system of the parent Specification is modified by the provision of buffer circuits between the charging memory M, which holds metering data during a call, and the exchange circuits and the processing circuits that handle the metering data at the end of a call. By placing the buffer circuits close to the memory M and its associated control circuit NP, problems of signal cross-talk are reduced. As shown in Fig. 1, the transmission junctors each have a buffer circuit such as ECC, the routing indicators have buffer circuits such as EIA, the exchange registers have buffer circuits such as EE, while the metering data processor CG has a buffer circuit ECG. When a register has full particulars from a calling subscriber a routing indicator is called in and, for metering, it activates its buffer EIA which places a demand for service from control NP which supervises access to memory M on a one-at-a-time basis. Given permission to proceed by NP, buffer EIA applies a back marking over the routing indicator, the register, and the junctor in use for the call. This mark is routed over leads AD and appears at the junctor's buffer circuit ECC which is identified by address marker MA to address the storage section of M associated with the junctor. Calling and called subscriber identities are then gated from buffer EIA to the store M on command from control NP. On detection of reply the register over its buffer EE applies to control NP which responds by the same process of backward marking to the junctor over leads AD to identify the junctor's storage section in M so that the charging code, charging rate or no charge, and the time of call connection from clock MT, can be stored. On detection of release in the junctor, the junctor's buffer ECC applies to a subordinate control circuit NS which calls up the call charge processor CG. Processor CG demands service from NP by application over its buffer ECG and provides the address marker MA with the junctor's identity by a code direct on wires ad. By this means the time of call disconnection is entered in the junctor's storage section in M and the total record there accumulated is read out to CG for the production of a permanent record such as magnetic or perforated tape, or punch card, or print out. The charging memory may be accessed by exchange operators to set up call particulars and register statistical data.
