Title: Improvements in or relating to the relaying of television pictures over wires
IPC: H04N7/10
Filed: 1953-06-03
Abstract: 763,194. Distributing music &c. BRITISH RELAY WIRELESS, Ltd., RUSSELL, K. A., and MACDONALD, D. A. May 25, 1954 [June 3, 1953], No. 15328/53. Class 40 (4). In a wired television relay system two screened cables are provided, each having two or more pairs over which video and audio signals are transmitted, and a sinusoidal signal, which provides line-scanning power, is transmitted over a phantom circuit using some or all of the conductors of each cable. As described, each of the cables 10, 11 has two pairs of conductors over each of which the video and audio signals pertaining to a separate television programme are transmitted. The four conductors (e.g. 12-15) are laid up as a quad around a central unpaired conductor (e.g. 16) and the whole is surrounded by a screen (e.g. 17) The combined vision and audio signals for the four television channels are applied to windings 30-33 of the four input transformers. The vision signals are in the form of amplitude modulation on a high-frequency carrier for example of 3.5 Mc/s. The frame scan waveform is applied to winding 50 and hence is transmitted over a circuit formed by the two central conductors 16 and 22 balanced about the screens of the two cables. The sinusoidal line scan power is obtained from generator 55 and is transmitted over a phantom circuit formed by the screens and the five conductors of each cable. This circuit effectively has conductors of larger section than the paths for the frame scan, vision and audio signals, which is desirable since the line scan power is substantially larger than that transmitted over any of the other paths. At each receiver the ganged contact arms 64, 69 serve to select the desired programme. The frame scan signals are applied to the two halves 80, 81 of a split time-base deflection coil, connected respectively between the centre conductors 16, 22 and the screens 17, 23. The two screens are also coupled through condensers 82, 83 to transformer 85 from which line defection power and E.H.T. voltage may be obtained as described in Specification 763,193. This power can be taken from the phantom circuit by coupling to the screens only since there is a large capacity between them and the conductors.

Title: Electro mechanical servo system
IPC: G05D3/12
Filed: 1953-06-04
Abstract: 743,225. Electric indicating systems. BENDIX AVIATION CORPORATION. June 4, 1953 [June 13, 1952], No. 15475/53. Class 40(1) In a selsyn system, an auxiliary signal, of greater magnitude and of opposite phase to the error signal, is generated, and added algebraically to the error signal when the transmitter and receiver rotors are displaced 180 degrees or more. The servomotor is then controlled by the auxiliary signal which prevents locking in of the receiver at the ambiguous 180 degree error position. As shown, for indicating total fuel flow to a plurality of engines, e.g. on an aircraft, the rotors R of selsyn transmitters 13/16, spring biased towards a zero position, are set individually according to the fuel flow to their respective engines. The selsyns are connected in cascade so that the angular position of the resultant field produced by the stator 20 of the selsyn receiver 22 corresponds to the sum of the settings of the four transmitters each of which is restricted to a movement of 90 degrees so that maximum total flow corresponds to one turn of the receiver rotor 24. The error signal developed in the receiver rotor is applied through an amplifier 27 to the control phase 28 of a two phase motor 29 which drives the rotor 24 in the follow-up sense and also sets an indicator 37. A brush 50 is also rotated by the motor in correspondence with the rotor 24 over a commutator 49 comprising two fixed semi-circular conductors 54, 56 arranged behind the indicator dial and energized in anti-phase over a transformer 59 from the same supply as that feeding the selsyn transmitters. A thyratron 69 has its grid energized from the receiver 22 and its anode energized over a transformer 65 from the brush 50. Normally the grid and anode are energized in anti-phase but when the rotor 24 deviates from its balance position by 180 degrees or more e.g. as a result of a change in the fuel flow while the amplifier is disconnected the grid and anode are energized substantially in phase. The tube fires, and developes an auxiliary signal in the transformer 65 which opposes and overcomes the error signal to drive the motor in the correct sense to remove the 180 degrees error, i.e. until the deviation is less than 180 degrees when the error signal again takes over control of the motor.

Abstract: 911,904. Fishing-reels. URFABRIKEN A.B. May 1, 1961 [May 2, 1960], No. 15736/61. Class 48. A spinning reel comprises a rotatable line guide 10 for winding the line 34 on to a fixed spool 9, a pin 11 projectable outside the line guide 10 to engage the line, a slide 12 carrying the pin 11 and radially displaceable within the line guide 10, a compression spring 33 urging the slide 12 to the projected position of the pin 11, a pair of catches 23, 24, Fig. 3, pivoted to the line guide 10 and adapted to hold the slide 12 in retracted position of the pin 11, and an abutment 32 on a fixed hub 7 adapted on rotation of the line guide 10 to release the catches one after the other. The catches 23, 24 have recesses 27 and are drawn together by a spring 26 so that, when the slide 12 is retracted by a plunger 18 engaging a wedge shaped part 17 of the slide, pins 29 on the slide engage in the recesses. The outer edges of the recesses are positioned relative to the pins 29 so that, as shown in Fig. 3, when the lower pin 29 abuts the edge of the recess 27 in catch 24 the other pin 29 is spaced by a small distance 35 from the corresponding edge of the recess in the other catch 23. When the line guide is rotated the fixed abutment 32 engages with flaps 31 on the edges of the catches and moves the catches in turn away from the pins; when the lower catch 24 is thus moved the slide is moved by its spring 33 until arrested by the other catch 23. This movement is sufficient to prevent the lower catch 24 from returning into engagement with its pin and when the other catch 23 is released the slide moves to the fully projected position of the pin 11. Inclined surfaces 28 on the ends of the catches 23, 24 slide on the pins 29 and cause the catches to move out of the path of the fixed abutment 32. The pins 29 may be on the catches and the recesses 27 in the slide. In a modification, Fig. 4 (not shown), the catches are constituted by blade springs and have bent in ends which engage with the forward end face of the slide to hold the slide in the retracted position of the pin 11.
