Abstract: 1332317 Measuring slip on wheels SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES 13 Nov 1970 [14 Nov 1969] 54249/70 Heading G1N In apparatus for detecting slip between two wheels of a vehicle by comparing voltages representing the individual speeds, facilities are provided for correcting one of the voltages for variations due to wear of the wheel. As shown, the two speed voltages 1, 2 are compared at 5. When the output signal is small, representing wear on one wheel, the output from 5 is fed through a memory circuit 8 to a gain control 9 which varies the amplification factor of one of the speed measurements to remove the difference output. When the output from 5 is large, representing slip between the wheels, a circuit 11 blocks the automatic gain control loop and operates an antislip device at 13, the memory circuit 8 retaining the wear compensation signal for use when the slip is terminated.

Abstract: 1369590 Photo-electric torque measurement DUNLOP HOLDINGS Ltd 16 Nov 1971 [19 Nov 1970] 54954/70 Heading G1A A photo-electric torque measuring arrangement of the type comprising two slotted interrupter discs 4, 5 mounted at two positions, on a torque sensing shaft or structure, between which there may exist a torque, each disc repetitively interrupting light from a source 14, 15 directed at a photo-detector 12, 16, is modified so as to be able to measure torque at low or zero shaft velocity, by the addition of scanning discs 7, 8, movable in a direction opposite to that of discs 4, 5, in the light paths  to introduce further interruption of the beams. The holes in discs 7, 8 may be spaced apart a larger distance than the slots of discs 4, 5, e.g. a multiple of the spacing of the slots, or an equal distance. When the spacings are similar the hole diameters should be narrower than the slots spacing to prevent a continuous beam of light reaching a photo-cell. The latter is associated with a reflecting cone so as to have a rectangular field of view which overlaps a number of slots of an interrupter disc. The scanning discs 7, 8 are rotated by the same motor or two synchronized motors. The outputs of the cells feed a phase sensitive frequency meter which monitors any phase difference in these outputs. A calibration procedure for the arrangement is described. Alternatives In Fig. 4 (not shown) instead of a single shaft bearing interrupter discs, the system is applied to two coupled shafts. A further arrangement, Figs. 5, 6 (not shown) has interrupter and scanning discs provided with a plurality of rows of slots and holes to give multi-range processing facility. Overload protection dogs are provided. A single light source may be used instead of the two 14, 15. It is stated that other forms of energy apart from light may be used with appropriate detectors.

Title: Indication of change of position of parts of a mechanical system
IPC: H03M1/00
Filed: 1970-11-23
Abstract: 1380388 Indicating movement TRADE & INDUSTRY SECRETARY OF STATE FOR 23 Feb 1972 [23 Nov 1970] 55532/70 Heading G4H In a system for indicating movement using an A.C. resolver, the output of a resolver fed with reference phase signals is converted to pulses. Each pulse in the resulting output train is then compared in logic circuitry with the preceding pulse in the pulse train delayed by the period of the reference phase signal. One or more clock pulses appears at a first output when the pulse in the output train appears before the pulse in the delayed train or at a second output when the pulses arrive in the reverse order. The outputs are fed to the up and down inputs respectively of a counter; a change of count indicating movement of the A.C. resolver. As shown, a 10 kHz clock pulse generator 14 feeds dividers 18, 22 to provide a 1 kHz sine output from filter 26 and a 1 kHz cosine output from filter 42. These form the reference phase signals to resolver 32. The sine wave output of resolver 32, which is displaced in phase relative to the standards by an amount related to the position of input 48, is converted to a pulse train and fed to logic circuitry 60. 10 kHz clock pulses are also fed to the logic circuitry, which is shown in detail in Fig. 2. An input pulse from generator 56, sets flip-flop 62, enables AND gate 64 and passes a clock pulse to monostable 68 which resets flip-flop 62. This synchronizes the input pulses with clock pulses. The pulses are then delayed 50 Ás (half the clock period) at 70 to prevent gating problems. The pulse is fed along line 72 and sets flip-flop 74, enabling AND gate 76 and supplying divider 78 with clock pulses. 500 Ás later the output of divider 78 resets flip-flop 74 and sets flip-flop 80. The thusenabled AND gate 82 passes clock pulses to divider 84, and after another 500 Ás an output is passed from divider 84 to delay 86 where another 50 Ás delay occurs. The signal on line 88 is thus the input signal on line 72 delayed by 1 ms.; the period of the reference phase signal. Line 72 is also applied to the set input of flip-flop 90 and the reset input of flip-flop 98 and line 88 to the other inputs of these flip-flops. When a pulse on line 72 arrives before a pulse on line 88, AND gate 92 is enabled and clock pulses pass on line 94 to the up input of counter 96 during the difference period. When the pulses arrive in the opposite order, AND gate 100 is enabled and the output is on line 102 to the down input of counter 102.

Title: Coded information-reading device
IPC: G06K7/016
Filed: 1974-12-24
Abstract: 1488172 Bar code reader CASIO COMPUTER CO Ltd 24 Dec 1974 [26 Dec 1973 13 May 1974] 55739/74 Heading G4M A data carrier, such as a magnetic drum or disc or a card carrying bar codes, is read by a read head or a hand held reader and signals are fed to input 10. The data is preceded by two marks S 1 , S 2  which are spaced by an amount equal to the space occupied by all the bits of a character of the data. Detection of the leading edge of the first mark sets flip-flop 21 so that clock pulses, are fed to counters 29a, 31. The leading edge of S 1  also operates delay unit 11, 12, 13 which produces a pulse when the trailing edge of S 1  occurs. This causes a "1" count to be entered into counter 16. When the mark S 2  is detected the delay unit 11, 12, 13 again generates a pulse at the trailing edge and via OR gate 15 supplies a pulse to AND gate 19 enabled by counter 16 so that flip-flop 21 is reset to stop the pulse supply to the counters, to shift the value in counter 29b to counter 30 and to reset counters 29a, 29b and 31. Counter 29a is arranged to overflow and feed counter 29b at a count equal to twice the number of bits in a character so that the value in counter 29b represents half of a bit period. Counter 16 is increased to a value "11". After a short time period a mark S 3  is detected and flip-flop 21 is set so that clock pulses are fed to counters 29a, 31. After half a bit period the value in counter 31 equals the value in counter 30 and coincidence circuit 32 enables gate 33 and resets counter 31. AND gate 34 enables gate 33 so at each half bit period a pulse is fed to a counter 35 which sets flip-flop 40 at the end of the character and a binary counter 36 which each bit period enables gate 31 to supply a shift pulse # to shift register 39. The input to the shift register is the train of bit pulses in each character from input 10. At the end of the character flip-flop 21 is reset. A further circuit is illustrated for use with records having only one marking between characters (Fig. 6, not shown) and a circuit (Fig. 7, not shown) is illustrated for use with non-return-tozero recordings.

Title: Improvements in or relating to multiple data sets

IPC: H04L5/22
Filed: 1970-12-10
Abstract: 1277535 Digital transmission systems; active filters WESTERN ELECTRIC CO Inc 10 Dec 1970 [11 Dec 1969] 58588/70 Headings H3U and H4P A multiple data set is employed for connecting a number of terminal units to a corresponding number of voice frequency lines. The set includes a receiver, transmitter, and processor, time-shared among the lines. Frequency shift signals received on a line are sampled in a respective line unit, the instantaneous signal amplitude sample causing a multibit number to be generated representing the sample. The numbers from all the line units are passed sequentially on a common line to a digitallyoperating frequency-shift receiver similar to that described in Specification 1,276,418. The receiver output is distributed to the terminals. Data from the terminals is multiplexed to a digitally-operating frequency-shift transmitter similar to that described in Specification 1,268,327, the transmitter output being distributed to the line units for transmission over the voice frequency lines. The operation of the data set is controlled by the processor. If there is no signal on a line the processor sets the receiver to detect ringing signals (20 c.p.s.) occurring in the time slots corresponding to the scanning of that line. Should the ringing signal frequency be detected the duration of it is checked to determine that it is not a spurious signal. The relevant terminal is informed of the signal and returns a "ready" signal to the processor, whereupon the processor causes the line unit to place the line in an "off hook" condition. After a period sufficient to allow any echo suppressors to be disabled a continuous Mark frequency is transmitted to indicate to the calling station that the terminal is answering the call. If the processor now detects that continuous Mark frequency is received from the line for a certain time the terminal is connected to both the transmitter and the receiver during the time slot pertinent to the line. Digital signals can now be transmitted or received. At the end of communicacation the processor places the line unit in the "on hook" condition. The receiver includes a circuit, Fig. 4 (not shown), switchable to detect ringing signals and carrier signals. The circuit receives the multibit input to the receiver as a first input and the sum of the outputs of the digital rectifier contained within the receiver as a second input. Under the control of the processor the first or second input is gated to a digital filter. The filter output is added to a threshold number to produce an output if the circuit is receiving either ringing or carrier signals; this output passes to the processor. When the circuit is set to detect ringing signals the filter response is modified by recirculating the number corresponding to a sample on a chosen line for a plurality of scan cycles so that the circuit can correctly operate when detecting the relatively low frequency ringing signals.
