Display controller for time recorders and time actuators

Claim 3

A device used in combination with a plurality of time recorders of claim 1, said device receiving recorded time in binary serial format over a single line from any one of said time recorders, comprising: (a) a single input line providing means for receiving recorded time in binary serial format one bit at a time, (b) means for converting said binary serial signal into BCD format, and (c) a display driven by said BCD signals showing time recorded numerically in days, hours, minutes and seconds.

Claim 4

A time actuator providing level shifting signal means over a time actuation line at preprogrammed times, said preprogramming being provided over a single time load line, comprising: (a) said time load line providing means of presetting the count in a shift register, (b) a digital clock emitting clock pulses, (c) a counter generating shifting pulses and a trigger pulse each frame driven by clock pulses from said digital clock, (d) said shift register preset by serial pulses from the time load line, whose contents are shifted by shifting pulses from said counter, the length of the shift register being equal to one frame, (e) a pulse generator triggered by said counter generating a pulse each frame, (f) an adder driven by said pulse generator and said shift register and recirculating its output to said shift register thereby augmenting the count of pulses in said shift register until the shift register has been filled following which cycle time actuation is reached, (g) a second adder driven by said shift register and said first adder resulting in a reset pulse at the output of the second adder, and (h) a flip-flop having its state reset by a reset pulse from said second adder when time actuation is reached.

Claim 5

A time actuator providing level shifting signal means over a time actuation line at preprogrammed times, said preprogramming being provided over a single time load line, comprising: (a) said time load line providing means of presetting the count in a shift register, (b) a digital clock emitting clock pulses, (c) a counter generating shifting pulses and a trigger pulse each frame driven by clock pulses from said digital clock, (d) said shift register preset by serial pulses from the time load line, whose contents are shifted by shifting pulses from said counter, the length of the shift register being equal to one frame, (e) a pulse generator triggered by said counter generating a pulse each frame, (f) an adder driven by said pulse generator and said shift register and recirculating its output to said shift register thereby augmenting the count of pulses in said shift register until the shift register has been filled following which cycle time actuation is reached, (g) a second adder driven by said shift register and said first adder resulting in a reset pulse at the output of the second adder, and (h) a flip-flop having its state reset by a reset pulse from said second adder when time actuation is reached.

Claim 6

A time recorder in combination with a time actuator wherein both functions of time recording and time actuation are obtained comprising the elements of claim 3 and, (a) an input line over which a triggering signal is applied to said pulse generator upon occurrence of an event, (b) a single output line over which the content of said shift register is transmitted in binary serial format one bit at a time, and (c) means for recirculating contents of said shift register thereby maintaining recorded time in said shift register while simultaneously transmitting recorded time.

Claim 7

A device used in combination with a plurality of time actuators of claim 3, said device transmitting actuating time in binary serial format over a single connecting line to any one of said time actuators, comprising: (a) a selector panel for selecting said actuating time numerically in days, hours, minutes and seconds (b) means for converting said actuating time into binary serial format, and (c) a single output line for transmitting said actuating time one bit at a time to any one of said time actuators.
