Title: Improved method of, and means for, recording electrical voltage surges
IPC: H01T1/12
Filed: 1952-09-29
Abstract: 732,375. Recording voltage surges. E.M.P. ELECTRIC, Ltd., and LLOYD, H. Dec. 29, 1953 [Sept. 29, 1952], No. 24327/52. Class 37. A sheet of recording medium such as paper is movable across a spark-gap and punctured by a spark on the occurrence of a voltage surge. The recording medium may be a paper disc movable manually or continuously clockwork or electrically-driven or driven by a stepping magnet actuated by the surges. In Fig. 2 a synchronous motor 11 rotates at a low speed (e.g. one revolution per week) a paper disc 14 between gap electrodes 21, 22 and the disc 14 is punctured when a voltage surge causes a spark across electrodes 21, 22. The latter are paraboloid or half-ellipsoid in shape and the paper disc 14 is appropriately graduated into weeks &c., Fig. 1, so that surge magnitudes and occurrence times are registered by the size and position of the punctures. The disc 14 is detachably held by knurled nut 16 between flanges 15 coaxial with an insulating disc 24 which covers the front of motor 11 and is secured to a tube 23 enclosing the electrode 21. The latter may be connected to a standard surge or lightning arrester via cable 18 whilst the other electrode 22 is position-adjustable and earth connected at 19. The cable 20 feeds low voltage to synchronous motor 11 mounted on pillars 12 within plastic casing 4. If desired the disc 14 may be normally stationary and rotatable periodically by hand, using knob 24, Fig. 1. A spring-pressed plunger may be associated with the casing 4 so that on removal of the cover 7 the whole of the internal mechanism is earthed via the cable 19. The Provisional Specification states that a graduated recording strip may be used instead of a rotating disc; the recording strip can be wound off a reel on to a take-up spool by suitable driving means.

Abstract: 640,874. Photo-electric amplifiers. SCOLES, G. J., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 22, 1948, No. 24794. [Class 40 (iii)] An electrical waveform is reproduced by causing it to drive a light modulating device 1 to vary the light from a source 2 falling on a sensitive cell 3, and feeding the output back in opposite sense after amplification at 4, to a further light modulating device 6, thereby providing negative feedback to correct distortion of the waveform due to non-linearity of the characteristic of the light-sensitive cell and to eliminate the effect of variations in the brightness of the light source. Alternatively the control devices 1, 6 may be placed in " parallel " to control separate beams from the source which are reflected back together on to the photo-cell, Fig. 3 (not shown). Light guides may be used between the source, control devices, and photo-cell, Fig. 2 (not shown), so that the first control device can be easily isolated from the rest of the equipment enabling the apparatus to be used as an H.T. current transformer. The light modulating devices may be Kerr cells or electromechanical such as a pair of gratings photographed on to a film and operated by a loud-speaker unit.

[Also in Division F4] A radiator is made from a synthetic plastics material (unspecified) reinforced with metal mesh, preferably a diamond-apertured expandedmetal mesh. In the method described for making the radia tor, the contiguous edges of two superimposed sheets or the unjoined contiguous edges of a folded sheet are sealed together by folding and pressure as shown in Fig. 2 ; whilst at this stage also, pipe connections 5 of metal or a plastics material, for the radiator fluid are positioned between the sheets. Thereafter the plastics material is softened by passing an electric current through the wire mesh, and then a high pressure fluid (liquid, air or other gas) is passed between the sheets to expand them to the surface of a mould of the required configuration. The sheet or sheet sections forming the radiator may be joined together by high frequency localized heating at selected points and/ or along lines 3.

Title: Improvements in or relating to machines for performing edge-setting or other burnishing operations on the margins of shoe bottoms

Filed: 1924-10-22
Abstract: 246,213. British United Shoe Machinery Co., Ltd., Barclay, W. B., and Keall, F. B. Oct. 22, 1924. Edge - setting and burnishing. - A shoebottom edge burnishing machine of the kind described in Specilication 14696/08 is provided' with means for modifying the action of the tool during one traverse of the shoe to produce a sleeking and finishing effect on the edge and to obviate the formation of ridges or humps on the edge. To this end a block 4 is moved by the ratchet counting mechanism 1 described in the above-mentioned Specification, at the commencement of the last traverse of the shoe, beneath a vertically reciprocating screw 20. The block and the bar 5 on which it slides are thrust downwardly by the screw and move, through linkage 11, 13 and a bell-crank lever 15, a belt-tightening roll 18 which by this movement slackens the belt 19 which vibrates the burnishing tool. The latter consequently merely presses, without vibration, against the shoe-bottom edge during the last traverse. To ensure this the belt is at the same time lifted from the driving pulley 27 by arms 31 operated by linkage 28, 29, 30. Arms 39 on the arms 31 then move a lever 35 the outer end of which engages an eccentric 34 on the tool oscillating- sliaft 33 to arrest the tool in the mid-position of its oscillation. The removal of the tool from the work at the end of the operation is controlled by the valve mechanism which reverses the traverse of the shoe at the end of each traverse and the jack is traversed back after removal of the tool, so that in a new operation the tool will first engage a straight part of the edge. Specification 153,938 also is referred to.
