Firing time control circuit

Claim 2

An adaptive control circuit for producing an output circuit signal at a time subsequent to an initial event as determined by an optimizing control system, comprising: (a) multi-stage delay line means having a plurality of output taps emanating from predetermined stages thereof and having an input terminal for receiving a pulse indicative of said initial event; (b) means for propagating said pulse through said delay line at a desired rate; (c) code responsive means coupled to said plurality of output taps for selecting only one of said taps at a time and delivering the signal thereon to a utilization device; (d) bi-directional counting means having its output coupled to said code responsive means; and (e) means for incrementing or decrementing said counting means by a predetermined count value as determined by said optimizing control system.

Claim 3

Apparatus as in claim 1 and further including means for initially entering a predetermined count value into said bi-directional counting means.

Claim 4

Apparatus as in claim 7 wherein said limit control means comprises a comparator circuit having means for entering binary coded signals representative of upper and lower limits as a first value therein and means for entering the output from said bi-directional counting means as a second value therein and having first and second output lines, said first output line carrying an output pulse when said second value exceeds said first value, said second output line carrying an output pulse when said second value is less than said first value.

Claim 5

Apparatus as in claim 3 wherein said means for incrementing or decrementing said counting means includes gating means connected to said first and second input lines of said comparator and to a source of clock signals, the output from said gating means being coupled to said bidirectional counting means.

Claim 6

Apparatus as in claim 7 wherein said means for incrementing or decrementing said counting means includes: (a) programmable pulse generating means for producing a predetermined number of pulses each time said programmable pulse generator receives a stimulating pulse from said optimizing control system; and (b) means coupling the output of said programmable pulse generator to said bi-directional counting means to increment said counting means by said predetermined number when said stimulating pulse is of a first type and for decrementing said counting means by said predetermined number when said stimulating pulse is of a second type.

Claim 7

Apparatus as in claim 5 wherein said means for incrementing or decrementing said counting means further includes: (a) a pulse generator coupled to receive control signals from said optimizing control system for producing pulses on either of two output lines depending upon the type of control signal being provided by said optimizing control system; (b) means coupling one of said output lines to the "up" input terminal of said bi-directional counting means and the other of said output lines to the "down" input of said bi-directional counting means; and (c) means for inhibiting said pulse generator during the time interval that said programmable pulse generator is active.

Claim 8

An adaptive control circuit for producing an output control signal at a time subsequent to an initial event as determined by an optimizing control system, comprising: (a) multi-stage delay line means having a plurality of output taps emanating from predetermined stages thereof and having an input terminal for receiving a pulse indicative of said initial event; (b) means for propagating said pulse through said delay line at a desired rate; (c) code responsive means coupled to said plurality of output taps for selecting only one of said taps at a time and delivering the signal thereon to a utilization device; (d) bi-directional counting means having its output coupled to said code responsive means; (e) means for incrementing or decrementing said counting means by a predetermined count value as determined by said optimizing control system; and (f) a limit control means coupled to the output of said bi-directional counting means for preventing the count in said counting means from exceeding in either direction predetermined upper and lower limits.

Claim 9

An adaptive control circuit for producing an output control signal at a time subsequent to an initial event as determined by an optimizing control system, comprising: (a) multi-stage delay line means having a plurality of output taps emanating from predetermined stages thereof and having an input terminal for receiving a pulse indicative of said initial event; (b) means for propagating said pulse through said delay line at a desired rate; (c) code responsive means coupled to said plurality of output taps for selecting only one of said taps at a time and delivering the signal thereon to a utilization device; (d) bi-directional counting means having its output coupled to said code responsive means; (e) means for incrementing or decrementing said counting means by a predetermined count value as determined by said optimizing control system; and (f) a limit control means coupled to the output of said bi-directional counting means for preventing the count in said counting means from exceeding in either direction predetermined upper and lower limits.
