Title: Encoded tag reader
Inventor: HAMISCH PAUL HELMUT
IPC: G06V30/224
Filed: 1967-12-28
Abstract: 1,218,349. Photo-electric reader and generator. MONARCH MARKING SYSTEM CO. Dec. 28, 1967, No. 58940/67. Heading G1A. [Also in Division G4] A hand-held device for sensing a sales tag or label of the type shown in Fig. 3, having concentric tracks 37-39 and a central hole or dimple 22, comprises a probe 12, Fig. 4, for engaging in the hole or dimple 22 and a sensing head which includes light conductors 191-193 leading to photo-detectors individual to the tracks 37-39. Probe 12 has at its upper end a conductive cap 25 which bridges contacts 26a, 26b when the probe is depressed against the action of spring 113 as it is engaged with the label 20, contacts 26a, 26b being in circuit with a motor which rotates the sensing head via gears 27, 28. A common light source 148 illuminates the label 20 by way of light conductors 181-183 which are distributed about their respective sensing conductors 191-193 Fig. 7 (not shown). The photodetectors comprise concentric annular rings of photo-voltaic or photo-conductive material on a plate 200 and having output leads 210-212, suitable apertures being provided in plate 88 for conductors 191-193, and the outer ring providing the timing pulses. Circuit Fig. 10. Bridging of contacts 26a, 26b sets a start flip-flop 320 so that simultaneous sensing of start mark 44 and a timing mark 49, Fig. 3, enables gates 321, 330 and sets flip-flops 340, 341. Subsequent rotation of the sensing head results in a train of timing pulses being applied to counter 305 while information pulses from track 38 are fed via distributing gates 361 to memory 300, and thence to a cash register, punch or data processor 303. When the sensing of each character, represented in 2 out of 5 code, has been completed, OR gate 366 re-sets memory 300 and counter 305 is primed for the next character cycle. Sensing of successive characters continues until the start mark 44 is again sensed, whereupon a re-set pulse is generated via gates 380, 377 and a lamp 34 on the sensing device 16, lit to indicate that sensing has been completed. A re-set pulse is also generated if, during sensing, the sensing device is lifted from the label prematurely (inverter 392), or if a line extending radially across all three tracks 37-39 is detected (gate 375).

Abstract: 1,148,710. Television; multiplex signalling. IIT RESEARCH INSTITUTE. 29 March, 1966, No. 59377/68. Divided out of 1,148,231. Headings H4F and H4L. In a colour television magnetic recording system, an audio signal and one or more colour video signals are recorded on one channel of the recording medium without interference between the signals by offsetting the audio signal relative to the colour video signal or signals in frequency. In a first embodiment, Fig. 1, a single recording head 600 is supplied with the monochrome output signal - Y, alternate lines of the X and Z colour video signals interleaved by means of switch 622 and converted to a suitable modulated carrier signal (e.g. a double side band amplitude modulated signal) by modulator 623 and local oscillator 630 (2À5 Mc/s.), and the audio signal which is converted to a suitable modulated carrier signal by modulator 634 and oscillator 635 (2À0 Mc/s.). Alternate pulses of the horizontal sync. pulses used to switch 622 and which are fed to mixer 620 have different amplitude or width to enable alternate lines to be recognized by the playback circuits (Fig. 2, not shown). In the playback circuit the colour video signals and audio signal are separated from the monochrome signal by means of tuned transformers, demodulated, and if the X and Z signals are required simultaneously instead of line sequentially the received signals are alternately delayed for one horizontal line scan interval by means of a rotating magnetic drum. In a second embodiment, Fig. 3, a first recording head 701 is supplied with the monochrome signal and a second recording head 702 is supplied with the X colour video signal, the Z colour video signal converted to a suitable modulated carrier signal by modulator 716 and oscillator 717 (1À2 Mc/s.) and the audio signal converted to a suitable modulated carrier signal by modulator 720 and oscillator 721 (1À8 Mc/s.). Suitable high-frequency bias may be injected into lines 730 and 731. For carrier recording of the X signal, the conductor 731 may have a modulator interposed therein with a local oscillator operating at 1À7 Mc/s. while oscillator 717 may operate at 0À7 Mc/s. and oscillator 721 at 60 kc/s. If a second sound channel is utilized as in stereo a further modulator may be provided having an oscillator operating at 120 kc/s. During playback the monochrome signal may be delayed. Frequency modulation may be used instead of amplitude modulation. For economy a two-colour system may be recorded, e.g. X, R - Y, or I with - Y.

Filed: 1970-04-06
Abstract: 1303129 Road traffic signals on vehicles WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 6 April 1970 [5 April 1969] 16196/70 Heading G4Q [Also in Division H2] In a vehicle lighting system having flashing direction indicator lamps which may be dimmed by series resistors, the resistors are switched in and out of circuit by a relay acting in synchronism with the flash generator, this relay only being operable when the side or head lamps of the vehicle are switched on. The relay is voltage operated and is arranged to have a delay action greater than that of an electromagnetic monitoring means associated with the flash generator. The synchronous switching of the resistor ensures that the difference between the "day" and "night" currents in the monitoring system are not too great whereby the flash frequency of the hot wire generator remains nearly constant; also, the pilot lamps operated by the monitoring system give acorrect indication both at day and night. In the embodiment of Fig. 1, flash generator BG controls front flash lamps BLV, rear flash lamps BLh and trailer flash lamps BLA on operation of a direction indicator switch FR to position L or R. A light switch LS switches on side lamps St in position I and main beam head lamp F or dipped beam head lamp Ab in position II depending upon the position of dip switch AbS. A brake light switch BrS switches on vehicle brake lamps Br and trailer brake lamps BrA. Movement of switch LS to position I or II also energizes relay TN2 to open contacts K5, K6 and insert resistors R5, R6 in series with the brake lamps Br, BrA. Also, relay contact K7 is closed so that the winding of relay TN1 is energized across the terminals L, R of the switch FR when that switch is operated and relay TN1 then operates in synchronism with the flash generator BG. This causes flashing of the indicator lamps in the appropriate side of the vehicle and also flashing of pilot lamps C1, C2. When relay TN1 is energized it opens contacts K1 ... K4 to connect resistors R1 ... R4 in series with respective rear flash lamps BLh and trailer flash lamps BLA. In fog conditions a switch ZS may be opened to render the relays TN2 and TN1 inoperative. In a modification (Fig. 2, not shown) the relay TN2 is omitted and instead the light switch LS has additional contacts to permit energization of the relay TN1. In a further modification (Fig. 3, not shown) the vehicle has fog head lamps and fog tail lamps operated by separate switches and when the fog lamps are energized the relays TN1 and TN2 are rendered inoperative. Also, the fog head lamps can only be energized when the dipped beam head lamps Ab are energized. A further switch causes all the direction indicator lamps to be simultaneously flashed to indicate an emergency and the operation of this switch renders the relays TN1, TN2 inoperative.
