Patent GB-745816-A (GB)
Title: Improvements in digital integrating devices, particularly adapted for differential analysis
IPC: G06F7/66
Filed: 1952-04-22
Abstract: 745,816. Valve circuits. BENDIX AVIATION CORPORATION. April 22, 1952, No. 10130/52. Class 40 (6). [Also in Group XIX] A digital calculating-device for performing integration (see Group XIX) employs valve circuits including the following: (1) a gate and associated stages of binary counters; (2) an anti-coincidence circuit; (3) a bi-stable trigger circuit and pair of associated gates; and (4) a switching circuit controlled by a bi-stable trigger circuit. (1) The gate 27, Fig. 7, receives negative pulses from the non-carry tube V0 of an associated X-counterstage. The pulse is passed through diode D2 to output line 67 or shunted through diode D1 according to whether the carry tube V1 of an associated Y- counter-stage is non-conducting (representing # 1 " ) or conducting (representing #0" ). Each stage of the X and Y counters comprises a bi-stable trigger circuit of the Eccles-Jordan type (not completely shown in Fig. 7) and associated with each Y-stage is a neon tube N1 connected to a line 80 whose potential is determined in such a manner that the neon tube lights when the true y-digit is # 1 " whether the Y-counter registers a true or complementary value. (2) Negative dx pulses on line 79, Fig. 11, are inverted and amplified in circuit 93 and sent to a one-shot multi-vibrator 94 whose square-wave output is differentiated in circuit 95 so as to apply a delayed negative pulse to the grid of a normally conducting triode V2. The negative dz pulses on line 70 are similarly applied through an inverter 96 to a one-shot multivibrator 97 whose square-wave output is applied directly to normally non-conducting triode V3 to cause conduction therein. Thus, only if a dx pulse occurs without a dz pulse will both triodes be cut-off-momentarily to produce a positive anode output pulse which is inverted in circuit 99. (3) A pair of gates (Fig. 12, not shown), similar to the gate 27, Fig. 7, are connected to opposite cathode circuits of an Eccles-Jordan type trigger circuit. (4) The switch 56, Fig. 13, includes four similar gates each comprising a lead 106-109, a shunt diode D9, D8, D7 or D10 and a further diode D13, D12, D11 or D14. The shunt diodes are in the cathode circuits of valves V6, V7 of trigger circuit 84 and further valves V8, V9 controlled therefrom over lines 88, 89. If valve V6, and therefore also V8, is non-conducting, negative pulses on leads 54, 53 are passed respectively through leads 108, 106 and diodes D11, D13, to channels 110 111; when, however, valves V7, V9 are non-conducting, the connections are crossed. The negative pulses on channel 110 cause a normally conducting valve V11 to be cut-off, thus producing a positive pulse at its anode which is limited to a fixed magnitude by a diode D15 and causes conduction in normally cut-off valve V12, thereby producing a fixed-magnitude anode output pulse on line 59. Channel 111 is connected by a similar limiting network to line 60. A mechanical reversing switch (not shown) may be inserted in the output circuits of valves V12, V12a.
