Title: Improvements relating to apparatus for number radix conversion
IPC: H03M7/12
Filed: 1955-03-10
Abstract: 769,735. Digital electric calculating-apparatus. GENERAL ELECTRIC CO. March 10, 1955 [March 10, 1954], No. 7085/55. Class 106 (1). In electronic decimal-to-binary conversion apparatus, each decimal digit is separately converted into a set of pulses representing the corresponding binary number and the sets of pulses are entered and placed in such positions in a binary accumulator as to build up the required binary equivalent therein. A 5-digit decimal number to be converted is set up on a keyboard 20, Fig. 1, the keys closing electric switches, whereby a pulse on one of the control lines 15 ... 19 is applied to the output line (1 ... 9) corresponding to the digit set up in the corresponding column a ... e. The lines 1-9 are connected to a rectifier or neon tube matrix which converts the digit into binary-coded form by selectively marking lines 11-14 (corresponding to values 8, 4, 2, 1) connected to the first four stages of a binary shifting accumulator 26 comprising e.g. Eccles-Jordan type two-state counting trigger circuits. The amount on the accumulator may be shifted one stage left by a pulse on line 27. In operation after a start switch 34 has been closed, gate 29 allows pulses from source 28 to step on frequency divider 30 comprising five two-state trigger circuits and thus having 32 conditions for each of which a different line is marked in " program " resistor matrix 31; pr selected combinations of the matrix lines are cormected to lines 15-19 and 27 whereby pulses, from source 32 (out of phase with 28) are applied via gate 33 in a predetermined 30-step cycle to lines 15-19 and 27 to cause the required converted binary number to be built up in the accumulator. When the cycle has been completed, a pulse is applied to line 36 to re-close gates 29 and 33. The number in the accumulator may be indicated by neon lamps, or may be transferred to a storage register or printing mechanism when the accumulator is cleared by a pulse on line 43. In a modification (Figs. 5 and 6, not shown), lines 11-14 are connected to a resistor-diode " shift " matrix controlled by the program matrix so as to direct the binary-coded digits directly to the correct orders of a non-shifting accumulator.
