Title: Ladder static logic control system and method of making
IPC: G05B19/05
Filed: 1973-06-15
Abstract: 1436726 Logic circuits CUTLER-HAMMER EUROPA Ltd 15 June 1973 [16 June 1972] 28677/73 Heading H3T In a logic system comprising a plurality of solid state logic circuits each responsive to an input logic signal and an operate pulse time delayed with respect to the input logic signal to provide a delayed output logic signal, therebeing associated with each logic circuit two gating circuits which are enabled and inhibited respectively in response to the delayed output logic signal, means are provided for generating the time delayed operate pulse in response to an input logic signal at any of the logic circuits and for causing simultaneous operation of all those logic circuits receiving said input logic signal. If the input at CC1 of Fig. 5 changes from a high level to a low level a low level output is produced on line CC19 and is fed to a Master Control unit, Figs. 7A, 7B (not shown). This produces an output "operate pulse" after a delay, which is applied to the terminal CC20 of Fig. 5 to switch bi-stable 60. When the operate pulse ceases, the bi-stable 62 switches its state and causes output line CC31 to change from a high to a low level. Thus the output switching is delayed by a predetermined time after the input switching. The output signal is fed to enable normally inhibited gates Fig. 3 (not shown) or via an inverter (58) to inhibit normally enabled gates Fig. 4 (not shown). The circuit of Fig. 5 may be modified for latching operation, Fig. 9 (not shown), or for timer circuit operation Fig. 10 (not shown). Master Controller, Figs. 7A, 7B (not shown), application of an input (on line A, B, C or D) starts an astable multivibrator (Q2, Q3) which feed pulses to a two-stage shift register (92, 94; 100, 102) after two pulses from the multivibrator an output pulse is produced (on line MC20) and a signal is fed back to stop the multivibrator until another input pulse is applied.
