Title: Wheel alignment apparatus
IPC: G01B11/275
Filed: 1973-08-09
Abstract: 1432699 Photo-electric wheel adjustment  ROYAL INDUSTRIES Inc 9 Aug 1973 [18 Sept  1972] 37835/73 Heading G1A The angular position of a wheel axis is adjusted with respect to the vehicle axis by photo-electric apparatus. The apparatus 10 of Fig. 1 is attached by magnet 11 first to the rear wheel hub as in Fig. 3. The axis 23 of the rear wheel is at right angles to the vehicle axis 24 and thus provides a reference. A mirror 20 is mounted at some distance therefrom on a substantially parallel axis to 23. Photodiode 17 is pulsed by generator 29 and reflected radiation from 20 reaches phototransistors 15, 16. The detector circuit comprises two parts; one, having a meter 32, indicating the difference in detector outputs, and the other having a lamp 34, indicating that both detectors are in fact illuminated. Mirror 20 is adjusted until equal outputs are obtained indicating that it is parallel with reference axis 23. The magnet 11 is then adjusted to tilt the device 10 through an angle equal to that required for the setting (toe-in) of the front wheels. The device 10 is then attached to the front wheel and the wheel axis angle adjusted until the detector outputs are equalized as indicated by meter 32. The indicating circuits include respective switches for altering the sensitivities of the amplifiers to allow for the different distances of the mirror 20 from the rear and front wheels, these switches being actuated by a pin 14, Fig. 3, which abuts a plate 27 on a rear wheel and energizes a relay 13, such a plate being absent from a front wheel.  The source generator circuit 29 energized by A.C. utilizes a uni-junction transistor and an SCR. The detector circuit includes after amplifier 30, a diode bridge detector 31. A diode (96) in indicator circuit 33 provides a threshold device which does not respond if neither or only one of the detectors is producing an output.

Title: Inspecting system for sampling finished workpieces
IPC: B24B49/02
Filed: 1971-08-13
Abstract: 1364066 Grinding TOYODA KOKI KK 13 Aug 1971 [25 Aug 1970] 38137/71 Heading B3D [Also in Division G3] In a system in which a workpiece 7 is measured while it is being ground to produce a signal when it reaches a predetermined size, the measuring device is adjusted by an error signal corresponding to the difference between a desired size and the actual size, measured at an inspecting station 20 to which workpieces leaving the machine on a delivery shoot 12 are deflected. Both measuring devices comprise feelers, 9, 21 coupled to differential transformers. The output of the first is amplified at 57, is adjusted by the error signal at 50b and operates a Schmitt trigger 50a to actuate hydraulic means 61 by which the workpiece is released and a new one substituted. The inspection sequence is controlled by a counter, which selects a predetermined sample of workpieces. A solenoid SOL1 moves a deflecting piece 19 with the dotted position shown and an electromagnetic valve actuates first a clamp, which comprises a piston with a self-aligning conical end to engage the centre bore of a workpiece (a ballrace), and secondly a piston, which brings the measuring head 20 into engagement with the clamped workpiece 7d. The complete sequence is controlled by timing relays but the hydraulic cylinder for the measuring head is coupled to that for the clamp, so that fluid from the latter, when it has acted, operates the former. The inspection station and clamping arrangements are described in detail (Figs. 2 ... 5, not shown).

Title: Electric motor control system
IPC: H02P7/26
Filed: 1959-11-16
Abstract: 911,796. Control of D.C. motors. WARNER & SWASEY CO. Nov. 16, 1959 [Dec. 15, 1958], No. 38718/59. Class 38 (3). [Also in Group XXXV] The armature 12 of an electric motor is supplied through thyratrons 17, 18, connected back-to-back and controlled by a signal voltage across lines 34, 35, the phase and magnitude of this voltage determining the polarity and magnitude of the current supplied to the armature. The signal voltage has four components corresponding to four input voltages to amplifier 40 which are applied at terminals 38, 39. A reference voltage applied through resistor 45 has a phase indicative of the desired direction of motor operation and a magnitude which represents the desired speed, a velocity feed-back signal being derived from tachometer generator 48 to oppose the reference voltage. A feed-back signal dependent upon the armature current is applied to the input terminals of the amplifier 40 in additive relation to the reference voltage so that, if the load tends to increase, an increase in armature current is effected to anticipate the load change. The current feed-back signal is obtained from resistor 20 through transformer 59, the polarity of the voltage applied to transformer winding 58 being the same regardless of which one of the thyratrons is conducting. The pulsating output current of the transformer 59 is smoothed in filter circuit 62. A third feed-back signal is applied to the input of amplifier 40 in opposition to the control signal applied through resistor 45, this feed-back signal being derived from acceleration tachometer 64 of the drag cup-type having a D.C. field coil 65 and output coil 66. The output current of the generator 64 is converted to A.C. in bridge circuit 72 and transformer 73 which has its output amplified in amplifier 103. The acceleration feed-back signal tends to prevent over-shooting of the desired rate of speed. A plurality of pulses, each indicating a desired increment of movement of the armature 12 may be applied to a reversible counter which sums the pulses, an analogue voltage being provided whose magnitude indicates the number stored in the counter. This voltage is converted to an alternating voltage to supply current through a phase-control circuit and resistor 45 to the amplifier 40. As the motor rotates, pulses indicating the removal of an increment are fed back to the reversible counter and subtracted from the number stored therein, Fig. 4 (not shown).

Abstract: 1448114 Digital transmission; methods of testing WESTINGHOUSE ELECTRIC CORP 22 Aug 1973 [24 Aug 1972] 39714/73 Heading H4P A method of testing comprises a computer 45 permanently located at station A, which as part of its function sends test signals to remote station B where portable apparatus 48 generates in response, input signals to local circuits, e.g. circuit card 52 or a computer (not shown) outputs from the card &c. being sampled and signals indicative of such sampling being transmitted to computer 45 which analyses them with programmed values to determine whether the card &c. is functioning properly. Test set 48 may include digital/analog/digital converters. Any fault found may cause the computer to transmit diagnostic information to station B for use by a test operator. The arrangement is used in conjunction with a full duplex system employing error correction by returning blocks to the originating station(s), for comparison with the corresponding transmitted blocks, simultaneous transmission being through an acoustic coupling such as a telephone link by means of fsk signals. Each data word, i.e. 16 bits is accompanied by a field code of say 4 bits defining a series of groups, e.g. 1-4 which are stored alternately on reception into odd and even registers, the bits being immediately retransmitted to the originating station for compairson with stored signals. As soon as group 1 has been found correct group 3 is transmitted (group 2 having been transmitted meanwhile) which indicates correct reception to the remote terminal hence group 1 is passed into a utilizing device. If incorrect, group 1 is retransmitted which replaces the faulty group 1. Groups, which are bounded by start/stop bits, are transmitted without time delay between words.
