Electrical control circuits for sequential energization and deenergization of programmed apparatus

Claim 1

AN ELECTRICAL CIRCUIT ARRANGEMENT FOR CONTROLLING THE SEQUENTIAL ENERGIZATION AND A DEENERGIZATION OF A PLURALITY OF CONTROLLED ELEMENTS, COMPRISING: A PLURALITY OF MONOSTABLE FLIPFLOPS EACH HAVING AN INPUT AND TWO OUTPUTS AND ADAPTED TO PROVIDE A VOLTAGE AT A FIRST ONE OF SAID OUTPUTS IF A VOLTAGE IS APPLIED TO SAID INPUT, AND TO PROVIDE A VOLTAGE AT THE SECOND OUTPUT IF NO VOLTAGE IS APPLIED TO SAID INPUT; MEANS CONNECTING SAID FIRST OUTPUTS OF SOME OF SAID FLIPFLOPS WITH RESPECTIVE ONES OF SAID CONTROLLED ELEMENTS; A PLURALITY OF CHAINS OF AND-GATES EACH ASSOCIATED WITH A RESPECTIVE ONE OF SAID FLIPFLOPS FOR CONTROLLING SHIFTING THEREOF; EACH OF SAID AND-GATES HAVING FIRST AND SECOND INPUTS AND ONE OUTPUT; ONE SINGLE, DIRECT CONNECTION BETWEEN THE FIRST INPUT OF EACH AND-GATE AND A SELECTED ONE OUTPUT OF ONE FLIPFLOP; MEANS INTERCONNECTING THE OUTPUT OF AT LEAST AN END ONE OF THE AND-GATES OF EACH CHAIN AND THE INPUT OFF THE ASSOCIATED FLIPFLOP; MEANS CONNECTING THE OUTPUTS OF THE OTHER AND-GATES OF SAID SECOND INPUTS OF SOME OF SAID AND-GATES; MEANS CONNECTING THE SAID SECOND INPUT OF THE INITIAL AND-GATE OF EACH CHAING TO A FEED VOLTAGE AND MEANS FOR SELECTIVELY APPLYING A COMMAND SIGNAL TO SAID SECOND INPUT OF AN INITIAL AND-GATE OF AT LEAST ONE OF SAID CHAINS, THE PATTERN OF SAID INTERCONNECTING MEANS ENSURING THAT APPLICATION OF SAID COMMAND SIGNAL PRODUCES THE DESIRED SEQUENTIAL ENERGIZATION AND DEENERGIZATION OF THE CONTROLLED ELEMENT.
