Time counter for electronic calculator - has logic circuit which gives control of set combination of time and number previously introduced into calculator

摘要

The electronic time counter is designed to be incorporated in an electronic calculator. The counter is of the type which includes a clock timer and adder and a register for the calculator. The counter connects the clock timer to the adder circuit and to the register by means of a control logic circuit and a memory and conversion logic circuit. The logic circuit are interconnectable and controllable and can be operated simultaneously, independently, or combined and automatically from the counter and from the adder circuit. The time counter has a double counting circuit connected to the timer by a first logic gate and two dividers, which are themselves connected to the memory and conversion logic circuit. The outputs of the counting circuit are connected to corresponding inputs of the memory and conversion logic circuit and to corresponding inputs of the control logic circuit. The control logic circuit is connected to the adder circuit via a second electronic gate.
