IPC: A63H17/39
Filed: 1959-04-15
Abstract: 872,342. Toy vehicles. REISER, R. April 15, 1959 [April 15, 1958], No. 12828/59. Class 132(3). An electrically driven toy vehicle is steered by remotely controlled electromagnetic means. As shown in Fig. 1, an electric motor 5 drives a rear wheel axle 2 through gears 9, 8, 7, 6, while the axle drives a toothed disc 18 through a worm 19. A control lever 16 linked to front wheel axles 11 and having a slot 24 fitting over the disc axle 25, carries two electromagnets 20, 21 by means of which it can be magnetically coupled to the disc 18 to effect the steering. With the disc rotating in the direction X, when the electromagnet 21 is energised, the rod is moved forward, within the confines of the slot 24, to turn the wheels 12, 13 to the right whereas, when the electromagnet 20 is energised, the wheels are directed to the left. In an alternative embodiment, the control lever 16 comprises two pairs of pivoted arms. In another alternative, Fig. 4, there is only one electromagnet 33, the steering wheels being biased by a spring 38 in a direction opposite from that in which the magnet 33 causes movement. As shown a driving disc 35 is vertical and the magnet has a counterweight 39 but the disc may be horizontal. In yet another alternative, Fig. 7, the disc 18 is arranged always to rotate in the same direction, independent of reversal of the motor 5, by' means of a cranked shaft 53, a slide 50 and a resilient arm 49 which engages the disc teeth. A resilient arm 54 prevents return rotation. The control lever may be of brass or aluminium the disc may be of iron.

Title: Improvements in coded electrical signal receivers
IPC: H04N7/16
Filed: 1949-05-17
Abstract: 669,583. Television receivers. ZENITH RADIO CORPORATION. May 17, 1949 [July 21, 1948], No..13121/49. Class 40 (iii). In a television receiver adapted to co-operate with the transmitter described in Specificaton 669,582, the key signal received by wire conductor from the transmitter is applied to a circuit which is controlled by the reception of the identifying signal so that only when the identifying signal is received does it pass the key signal to a device for decoding received television-picture signals. The television-picture signals received by circuit 2 are applied via circuit 3 to modulate the electron-beam intensity in cathode-ray tube 4. Synchronizing-signal separator 5 passes frame synchronizing pulses to frame-sweep signal generator 6 and line-synchronizing pulses to linesweep signal generator 8 via delay device 9. Delay device 9 is controlled by the simultaneous application to unit 13 of frame-synchronzing signals from unit 6 and key signal received over the telephone lines 11a to pass the line-synchronizing signals applied thereto to generator 8 with or without a delay in synchronism with the operation of a similar delay device at the transmitter. Identifying signals modulated on to the radio carrier-wave carrying the concomitant sound transmission and received by circuit 15 are separated by the filter unit 18 and applied to the switch circuit 12 which blocks the circuit from the lines 11a to the unit 13 except when the identifying signal is being received. Thus only when the appropriate television programme is being received does the key signal perform its decoding operation. Specifications 647,892 and 647,893 also are referred to.

Abstract: 1,049,916. Automatic frequency and phase control. FERNSEH G.m.b.H. March 31, 1964 [March 28, 1963], No. 13134/64. Heading H3A. In an arrangement for synchronizing signals generated by a flywheel oscillator C and synchronizing pulses applied at terminal 1, the oscillator and synchronizing signals are applied to a first phase discriminator A which develops an output voltage V 1  which is applied via filter B to control the oscillator and the oscillator signals are then applied to a voltage variable phase shifter D which is controlled by the output of a second phase discriminator F to which the synchronizing pulses and the phase shifted output signals O 1  are applied. The arrangement may be used to stabilize jitter in the output video signal of a tape recorder, Fig. 2 (not shown), by deriving a line frequency signal which is synchronized with the mean phase of the line synchronizing signal in the video output signal and controlling a delay circuit connected in series with the video output by the output voltage of a pulse discriminator to which the derived line frequency signals and the line synchronizing signals are applied.

Abstract: 874,837. Winding &c. apparatus; taking up slack of cables &c. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 1, 1960 [April 20, 1959], No. 13463/59. Classes 78 (2) and 78 (5). [Also in Group XXVIII] A cable 4 is secured to a rotatable storage reel 5 at an intermediate point 20 so as to divide the cable 4 into a part on the reel and a part retained in the form of a flat spiral coil 41, the arrangement being such that as the reel is rotated to pay off or draw in the first part of the cable, the diameter of the turns in the coil 41 changes. Thus, however much cable is paid off or drawn in by the reel 5, the length of cable in the spiral remains constant, and the cable at the outer periphery of the spiral may be fixed to a part 43 rigid with fixed frame plates 7, 8, and no twisting of the cable occurs. As shown, the cable 4 supports and contains the conductors for a television camera 1 for examining the core structure of a nuclear reactor. The part of the cable on the reel 5 is concentric with a hose 3 leading at 20 to the interior of the hub 6 of the reel 5. Coolant gas is supplied to the hose 3 via a sealed coaxial connection 73. The inner end of the cable 4 is internally coiled within the hub 6 and then passes through an elbow-shaped member 70 which is rigid with the hub 6. Also rigid with the hub 6 is a block 30 around which is wound the first turn of the coil 41. A spiral spring 35 is interleaved with the turns of the coil 41, and has its inner end fixed to the block 30 and its outer end 38 to side plates 26, 27 which are secured to the frame of the device. The cable 4 passes out through a gap 42 in a circumferential channel member 28 joining the plates 26, 27 to the connection at 43. The hub 6 is supported for rotation relative to the fixed frame plates 7, 8 by three ballbearing mounted rollers 59 and three similar rollers 58. The hub is located axially by a groove 70 which engages the rollers 58. The reel 5 is rotatable by a handle 78. This acts through a ratchet mechanism which may be set to hold the camera 1 against downward movement, but permits it to be raised. Alternatively the ratchet mechanism 103 may be disconnected by a lever 110 to permit the camera 1 to be wound up or down.
