Title: Improvements relating to electric circuit-breakers
Inventor: WRIGHT EDWARD GORDON
IPC: H01H1/58
Filed: 1959-03-12
Abstract: 882,691. Switch contacts. OTTERMILL SWITCHGEAR Ltd. Feb. 25, 1960 [March 12, 1959], No. 8626/59. Class 38 (5). The contact assembly for each phase of an oil circuit-breaker comprises two identical sets of spaced fixed contacts bridged, in the breakerclosed position, by a vertically-movable bar 50, Fig. 2 (not shown). Each contact set consists of a pair of spaced terminal plates 2 whose outer faces 4 engage brackets 8 and the hooks 20 of four pairs of aligned contact fingers 1, which pivot about pins 23 and are urged inwardly by springs 25 enclosed by housings 30 whose lower ends 32 form stops for the fingers 1. With the breaker open the face 53 and hook 20 of each finger 1 engage members 4, 23 respectively, but upward movement of the bar 50 to engage first the arcing tip 41 and then the finger 1 causes upward and outward movement of the latter to engage the hook 20 with members 4, 13. Thus, during the closing and opening movements a rolling action occurs between members 1, 50 and 4, 20, and arcing takes place only between members 41, 50 and 13, 20. Members 1, 8 are preferably of a different material and members 1, 2 and 50 have silver surfaces. In a modification the end of the hook 20 is extended to engage the spring 25, thus ensuring that only the surfaces 4, 54 engage when the breaker is open.

The plates 2 need not be continued above the arm 7 and can be replaced at this part by two lines of links 11 connected by a cable 5, passing over a pulley 12, to a shock-absorbing spring 6. The links 11 and cable 5 may be replaced by a pair of cables 5a one on each side of the wheel. The plates 2 have lugs 3 connected by links 4, the lugs preventing the plates from bowing inwards towards the tyre. The plates can be restrained from falling to the vertical position by a leaf spring 24 and may have spikes or protuberances 25 on both sides.

Patent GB-644128-A (GB)
Title: Telemetering system
IPC: G08C15/08
Filed: 1947-04-03
Abstract: 644,128. Telemetering systems. STANDARD TELEPHONES & CABLES, Ltd. April 3, 1947, No. 9066. Convention date, April 6, 1946. [Class 40 (i)] A telemetering system consists of means for transmitting over a common transmission medium a plurality of meter readings to one or more points by means of single electric pulses time-modulated or groups of impulses frequency modulated in accordance with the instantaneous value of each of the said meter readings, and means at the receiving end for segregating the pulses to operate individual indicators to reproduce the indications of the original meters. The meter indications may be converted into electrical quantities either directly, if an electrical meter 1, or indirectly if mechanical meters 2, 3, 4, by adapting the moving part of the meter to effect an electrical change, either of magnitude or frequency. The various electrical signals are fed to a series of plates 45 on a cathode-ray tube 9, which normally produces a circular sweep of the beam from an oscillator 42 and sweep circuit 41. The electrical quantities on deflection plates 45 cause radial deflection of the beam as it passes through slots 48 on target plate 47, to impinge on a collector electrode 51, thus producing a series of single pulses a, b, c, &c., each being time-modulated in accordance with the amplitude of the electrical quantity on the plates 45 and a series of groups of impulses d frequency modulated in accordance with the frequency of oscillator 33. These are taken to a transmitter 55, whose transmitted wave is thus a sine-wave 57, Fig. 2, with a series of pulses a, b, c, &c. to which is added a synchronizing pulse s. At a receiving point, Fig. 3, the signal wave is taken to a synchronous pulse separator 61 to operate an oscillator 63 and sweep circuit 65 in synchronism with the sweep circuit 41 of the transmitter, and is applied to the deflecting plates of a cathode-ray tube 68. The signal wave is fed to the control grid 70 of the cathode-ray tube 68, so that the electron beam is modulated by the pulses, and each series of pulses a, b, c, &c. is segregated by the apertures 75 of a target plate 74 and produces on targets 76 in the case of channels a, band c pulses which are amplitude modulated in accordance with the phase of the signals. The signal in channel d produces frequency modulated pulses which may be interpreted by a frequency meter. The meters may be recording meters. Specification 603,614, [Group XL (a)], is referred to.

Abstract: 827,697. Magnetic record apparatus. MULLER, W. March 21, 1958 [March 7, 1958], No. 9071/58. Class 40 (2). In a sound record apparatus employing a sleeve-shaped magnetic record carrier mounted on spaced rollers and having a guide groove therein to guide the transducer, the drive mechanism comprises a friction wheel 56 mounted on the shaft 53 of a driving roller 24 and coupled by a belt 59 to a pulley 60 having a friction rim 62 and mounted on a rocker arm 63 which is pivoted about the shaft 53 and has a slot 80 in which the support of an axle 82 of a stepped friction-wheel 83 is biased by action of a spring 93 so that its smaller diameter step 84 is in constant contact with the friction wheel 56, and means whereby the rocker arm 63 can be swung from a neutral position in which the drives the rim 62 of pulley 60. The rocker arm 63 is moved by electromagnets 67, 68 acting on an extension 65 thereof. The neutral position is maintained in the absence of current in the magnets by springs 71, 72. The extension 65 operates electrical contacts 78 to complete the circuits of suitable indicator lamps 39. The transducer support arm comprises an elbow linkage which permits the transducer to shaft 51 of a motor 50 runs idly, to a forward drive position in which the shaft 51 engages the larger diameter of the stepped wheel 83, or to a reverse drive position in which the shaft 51 follow a rectilinear guide path. An crazing magnet 163 is mounted in the base of the machine and extends over the full width of the record band, and is moved up into contact with the band about a pivot 164 by the action of a push-rod 166 operated by a lever 172 which can only be tuned after moving in a longitudinal direction.
