Abstract: 393,097. Control of motors. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. June 25, 1932, No. 18005. Convention date, June 25, 1931. [Class 38 (iii).] Travelling to predetermined limits.-An electrical control device for radio-receiving apparatus &c. comprises a control shaft 6 adapted to be rotated to a preselected position or positions by an electric motor 18, a contactor or contactors 17 for controlling the motor, a cam or cams 13 frictionally mounted on the shaft and means such as spring-restrained pushbuttons 37 co-operating with slots 36 in flanges 41 on the cams for holding a cam in fixed relation to its contactor when the control shaft is rotated to change the pre-selected position, the arrangement being such that each cam is adapted to actuate its contactor so as to de-energize the motor and stop the control shaft at the preselected position without the necessity for providing a positive stop. Each contactor 17 co-operates with a fixed contact 21 for one direction of rotation of the reversible motor 18 and with a contact 22 for the opposite direction of rotation, these fixed contacts being carried by conducting bars 23 connected in circuit with the motor as shown in Fig. 2. The cams are frictionally connected to the shaft by plungers 35 of aluminium or leather held in hubs 33 of the cam discs and pressed against the shaft by garter springs 34. The motor is operated by closing any one of the switches 25 by pressing a selector button 45 and the button is held depressed until the motor stops by the opening of the circuit at the corresponding contactor 17. In this position the notch 36 of the cam disc lies directly opposite the end of the setting plunger 37 which is then pressed to lock the cam in a fixed position with the contactor open. By manual operation of a knob 8, the control shaft is then turned so that the tuning condenser 5 is in the correct position for the particular station desired and the setting button is released. Thereafter, if the tuning control shaft be in any other position, pressure of the button 45 will cause the corresponding cam member 13 to open the contactor 17 at the same setting as before. The same operation is repeated for all the other cams. The selector buttons 45 and setting buttons 37 are mounted on a panel 39 and between the two rows of buttons a readily changeable indicator card 46 is held in a channel holder 47. Extension wires 32, Fig. 2, may be provided for remote control. Specification 341,464, [Group XXXVIII], is referred to.

Title: Improvements in and relating to binary counters
Inventor: CARROLL WILLIAM NICHOLAS
IPC: H03K21/00
Filed: 1961-05-19
Abstract: 908,555. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 19, 1961, No. 18285/61. Class 40 (1). [Also in Group XIX] The storage register of a binary counter is so controlled by logic circuits that in response to stepping pulses it stores odd numbers in true form and even numbers in complement form except for the lowest stage. The register controls further logic circuits so that read-out is always effected in true form. The register comprises flip-flops 10-18 and a lowest stage 44. A clear pulse sets all the flipflops to 1 except the lowest which is set to 0. In counting pulses on line 50, according to whether stage 44 is at 1 or 0 so gate 46 or 48 opens. With stage 44 at 1, a stepping pulse reverses 44 and samples gates 26-34. Any of these gates which is open because the corresponding stage is at 0 sends a pulse to all the OR gates 36-42 of higher denomination to effect complementing. If stage 44 is at 0, all the OR gates 36-42 are effective to effect complementing at the same time as 44 changes to 1. Read-out. The 1 and 0 outputs of the register flip-flops feed gates 56-64 and 66-74 respectively. One or other set is opened by gate 88 or 90, at read-out, according to whether flip-flop 44 of the lowest denomination registers 1 or 0. The read-out on leads 2<SP>5</SP>-2<SP>0</SP> is therefore in true form.

Title: Optical label scanning
IPC: B61L25/04
Filed: 1971-06-02
Abstract: 1348037 Vehicle identification IDENTICON CORP 2 June 1971 [10 June 1970] 18592/71 Heading B7N [Also in Division G1] In an identification system for rail vehicles each vehicle carries coded labels 10 each with horizontal, light reflecting stripes 12-16 which have widths a, 3a in scanning direction A which are less or greater than the width 2a of first stripe 11, the latter width being used as reference in reading apparatus for the labels. Light from source 21 is directed via lens 22, apertured mirror 23 and mirror scanning drum 24 to the label 10 and the reflected light is passed via the drum, the aperture 23a in the mirror and lens 26 to detector 26. The pulse signals from the detector and a vehicle present signal from sensor 32 are passed to decode circuit 30. A vehicle present signal on line 31 actuates flip-flop 41 to apply a reset signal to the various flip-flop and registers in the decode circuit. The first stripe pulse opens gate 52 applying clock pulses CP to reference width counter 54 and the end of this pulse switches over flip-flop 55 thereby disabling gate 52 and enabling gates 56, 57. The coded data pulses now gate clock pulses to the data counter 61 where the number of clock pulses per data pulse is compared with the reference in counter 54. Counts greater or less than the reference produce "1" or "0" signals from comparator 63 and these signals are fed during successive scans of the label to shift registers 45, 46. If the shift register signals compared in unit 47 agree then flip-flop 73 is set so that when the "leave read zone" signal is applied to gate 74 the number in register 46 is read out to converter 75 and register 76. The code form, i.e. two out of five, is checked in unit 66 and the expected number of digits is checked in unit 71, any error producing a reset signal. If the flip-flop 73 is not set error indicator 82 is actuated by the "leave read zone" signal. In a second reading arrangement the label is imaged on the face of a C.R.T., Fig. 5 (not shown). The label stripes can be circular Fig. 8 (not shown) or the cross-section of the scanning beam can be elongated in the direction of vehicle motion and the stripes made shorter than this dimension of the beam Fig. 7 (not shown).
