Patent NL-6514377-A (NL)
IPC: H04L9/00
Filed: 1965-11-05
Abstract: 1,122,639. Pulse signalling. CIBA Ltd. 5 Nov., 1965 [6 Nov., 1964], No. 47059/65. Heading H4L. Apparatus for coding signal pulse sequences to ensure secrecy comprises means for mixing each signal pulse of a sequence with a different pulse in a pseudo-random pulse sequence to provide at the output combined pulses on the occurrence of one binary value in an auxiliary binary code pulse sequence, and means acting on the occurrence of the other binary value of the auxiliary pulse sequence for adding a predetermined pulse amplitude value to said combined pulses when the amplitude value of the latter does not exceed a predetermined threshold value and for subtracting said predetermined amplitude value when the amplitude value of said combined pulses does exceed said threshold value. In a circuit for coding quantized amplitude modulated pulses, Fig. 9, the signal pulses K, and pulses S whose amplitudes vary discretely in a pseudo-random manner, are added at 22 and supplied via an OR gate 35 and AND gate 39 to the output C. The combined pulses are also supplied to a threshold detector 24, supplying an AND gate 28, and via an inverter 25, to an AND gate 29. Gates 28, 29 and 35 are controlled by the auxiliary pulse sequence S<SP>*</SP>. It it assumed that amplitude values in the pulse sequences K and S differ by steps of 0.1 volt and that the amplitude values in each case may extend from 0 to - 1À5 volt. Thus the combined pulse sequence may have values extending from 0 to- 3À0 volts. The auxiliary binary coded pulse sequence S<SP>*</SP> has the two values-6 volts or 0 volt representing 0 and 1 respectively. When the value 0 occurs in the pulse sequence S*  the gate 35 passes to the output the more positive of its two inputs, i.e. the combined pulse output from 22. Gates 28, 29 are blocked and provide a signal blocking a subtraction circuit 33 and an addition circuit 34 so that 0 volts appears on lines 37, 38. Since gate 39 passes only the most negative potential at its inputs, the output of 22 passes to the output C unchanged. The occurrence of binary 1 in the sequence S<SP>*</SP> causes gate 35 to transmit the value O volt to the output gate 39. The threshold detector 24 provides an output potential of 0 volts as long as the amplitude value of the combined pulse sequence is less than 1.6 volt and of - 6 volts when the amplitude value is equal to or greater than 1.6 volt. Thus a signal will be passed by gate 32 when the output of threshold detector 24 is 0 volt and by gate 29 when the output is - 6 volts. Gates 31, 32 control circuits 33, 34 respectively, circuit 33 causing 1.6 volt to be subtracted from the combined pulse sequence appearing at the output of circuit 22 and circuit 34 causing 1.6 volt to be added. The decoding circuit, Fig. 10 (not shown), operates on similar lines. The input signal and pseudorandom pulse sequences may be in binary coded form, Figs. 11, 12 (not shown), and the required addition and subtraction obtained through counting chains.

Abstract: 1,248,742. Position encoders. PRECILEC. 24 Oct., 1968 [24 Oct., 1967; 6 Sept., 1968], No. 50481/68. Heading G4H. A transducer measuring the relative position of two members to give an amplitude-significant signal and an analogue-digital converter digitizing the amplitude signal are fed with the same source as the reference signal. In the embodiment of Fig. 1 signals u 1  = E sin # . sin wt, u 2  = F cos # . sin wt, u 3  = - E sin # . sin wt and u 4  = - E cos # . sin wt representing the angular displacement # of the primary winding of resolver 10 are first compared with zero to determine which two signals are positive. The associated two comparators are then enabled to compare their two inputs with a stepped reference signal derived from voltage divider 6, each step being counted in an auxiliary counter 7 until one of the two comparators is operated. The logic circuit 5 then sets a counter 9 to a level dependent on which two comparators were initially enabled and which comparator operated first and counter 7 is counted down to 0, counter 9 being simultaneously incremented or decremented from its set level under the control of the logic circuit. The count is stored in a register 14 and may be displayed. The voltage divider (Fig. 3, not shown) comprises a parallel resistor chain the resistances being switched under the control of transistor switches operated by the outputs of counter 7. In the embodiment of Fig. 7 the signal from a potentiometer 18 representing the angular or linear position of its slider 17 are compared with four stepped reference voltages representing four possible ranges of the input. Initially the reference voltages have the values 0, v/4, v/2, 3v/4 to determine the range in which the input lies. The reference voltages are then stepped and as in the embodiment of Fig. 1 pulses simultaneously counted in auxiliary counter 7. The counter 9 is preset by the logic circuitry 5 in dependance on the range in which the input is found to be. The apparatus of Fig. 1 may be modified to include coarse and fine transducers, the coarse transducer giving twice the required resolution, i.e. an auxiliary digit 0 or 1 and the fine transducer dividing one coarse digit into a hundred increments. A logic circuit adds one to the coarse value if the auxiliary digit is " 1 " and the fine value is between 0 and 25 and subtracts 1 if the auxiliary coarse value is " 0 " and the fine value is between 75 and 99. Alternatively a three-stage system, i.e. coarse, fine and medium may be used.
