Title: Improvements in a two-speed sprocket wheel device
IPC: B62M11/14
Filed: 1939-09-11
Abstract: 535.692. Change-speed gearing. BOWEN, L. G. Sept. 11, 1939, No. 25559. [Class 80 (ii)] In two-speed gearing suitable for cycles, of the kind comprising a sprocket-wheel provided witn planet-pinions co-operating with an annulus on a driving-member, and a sun-gear which is locked to the driving-member for high gear or is held stationary for low gear, a change-speed member can be moved into position for unlocking and holding the sun-gear only during forward movement of the driving-member. In the gear shown in Figs. 3, 8 and 10, a disc 29 on the pedal crank-shaft 27 is provided with a ring 30 having teeth 31 for engaging a coupling-dog 110 pivoted on a sun-gear 40. Teeth 41 on the sun-gear and a toothed annulus 36 on the disc 29 co-operate with planet-pinions 67 mounted on disc 57 provided with sprocketteeth 59. A change-speed member 80 consists of a ring which is arranged in a stationary ring 69 and can be rocked transversely on a pivot by means of springs 108. A pin 83 on the ring 80 engages a slot in another ring 95 which can be moved in either direction by a cable. In the high-gear adjustment, the pin engages the slot closely, whereas in the low-gear adjustment, the pin is in register with an enlargement in the slot. In the high-gear adjustment, a nose 121 on the dog 110 engages one of the tooth-spaces 32 of the disc 30, and the member 81 is ineffective. In the low-gear adjustment, forward movement of the pedals causes a gap 44, 48 in a flange 42 on the ring 40 to register with a gap 74, 73 in a flange 72 on the ring 69, a member 81 of the ring 80 is projected, a nose 126 thereon co-operates with the part 127 of the dog, the dog is raised, and the nose 121 is released from the ring 30. Slight backward movement of the sun-gear 40 then occurs, and the part 84 of the member 81 co-operates with a nose 136 to lift the dog out of engagement with the ring. The member 81 then co-operates with the gap 44, 48 to hold the sun-gear in stationary position and a projection 78 on the member l olds the dog in released position. If the rider back-pedals before the dog is released from the ring 30, the parts remain in high-gear, since the nose 126 co-operates with the nose 130 of the dog and the part 47 of the flange 42 to cam back the member 80.

Title: Track for electrically powered miniature vehicles
IPC: A63H18/02
Filed: 1959-07-28
Abstract: 894,837. Miniature-vehicle tracks. WRENN, G. R., and WRENN, C. R. Sept. 17, 1959 [July 28, 1959], No. 25865/59. Classes 132(2) and 132(3) A miniature-vehicle diverting device is such that it will divert an electrically powered vehicle by engaging a guide member or members on each vehicle with a member in a vehicle guiding slot to lift the guide member or members from the slot and to divert the vehicle from one lane of a track so that it will run under its own momentum to an adjacent lane. Each lane has a guide slot, e.g. 25, Fig. 1, engageable by one or more downwardly projecting guide members from a vehicle and also has electrically conductive strips 28 to 31 inserted in it engageable by current collectors. Each vehicle has a pair of current collectors, the collectors of different vehicles on the same lane engaging different pairs of conductors so that, by controlling the current supply to the strips, the speed of the different vehicles can be independently controlled. Figs. 3 and 4 show an insert frictionally fitted in a guide slot, the insert comprising an upwardly sloping face 47 and a laterally slanting face 49. As a vehicle travels along the lane its guide member is raised out of the lane slot by the face 47 and is deflected sideways by the face 49. Thus the vehicle is deflected from its lane to an adjacent lane where its guide member drops into a guide slot and its collectors make contact with the conductors. Fig. 6 shows an alternative embodiment where a similarly shaped deflector is pivoted at 51 and is operated through a cranked spindle 55 by a lever, Bowden cable or solenoid. Vehicles may be raced by controlling the diverting devices and current to the strips, the vehicles overtaking each other by changing from one track to another and back again. According to the Provisional Specification, instead of a guide slot, a raised guide rail having conductor strips incorporated in it or a pair of guide grooves for miniature-car wheels may be used. The Provisional Specification also describes overhead wires for miniature trolley buses or trams and points similar to those used in model railway tracks. Specification 844,436 is referred to,

Abstract: 1,149,626. Television signal recording. AKAI ELECTRIC CO. Ltd. 14 June, 1966 [8 Feb., 1966], No. 26391/66. Heading H4F. In an arrangement for recording and subsequently reproducing television signals with the aid of magnetic tape apparatus, the signals before recording are converted from the conventional form shown in Fig. 1, where the synchronizing pulses occupy the range 0 to - 40%, to the form shown in Fig. 2 where the pulses occupy the range extending from 0% to a value in excess peak white and preferably of the order of 140%. After reproduction the signals are restored to the conventional form again before use for image reproduction. The effect of the invention is to produce a signal for recording in which, in response to picture variation between all black end all white, the mean signal varies less than with a conventional signal. Since the signal is A.C. coupled to the recording head, this permits a signal of larger amplitude to be accommodated within the dynamic recording range of the tape magnetic material with a consequent improvement in the signal-to-noise of the signal when reproduced. Detailed transistor circuits for effecting the signal conversions are described with reference to Figs. 8-11 (not shown). The general procedure is to separate the synchronizing pulses from the picture signals (clipping below black level in the conversion from Fig. 1 to Fig. 2 before recording and clipping above peak white level in the conversion from Fig. 2 to Fig. 1 after reproduction) and after amplification and reshaping to recombine the pulses in opposition with the original signal with the appropriate amplitude relationship to bring about the conversion. The circuit used during reproduction also includes the conventional arrangements for effecting frequency and phase compensation to allow for the recording and head characteristics.
