Patent GB-894943-A (GB)
Title: Improvements in and relating to means for testing insulating material for dielectricloss
Inventor: SIMONS JOHN SPENCER
IPC: G01R27/26
Filed: 1959-05-05
Abstract: 894,943. Measuring bridges; testing faults. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 26, 1960 [May 5,1959], No. 15434/59. Class 37. Apparatus testing for or detecting dielectric losses of a capacitance due to ionization of gas in voids of the dielectric comprises a bridge having non-reactive resistances R1, R2 (or equivalent loss-free capacitances) as ratio arms completed by the test capacitance member incorporating a dielectric specimen C4, shown shunted by loss resistance R4, and a variable capacitance C3 shunted by a variable resistance R3 which may be switched out of circuit. The junctions J1, J2 of the test and ratio arms are respectively connected to the X, Y plates of a graticuled cathoderay oscillograph returned to earth together with the bridge, which is excited by a high alternating voltage. Initially R3 is switched out and the shape of the trace is noted; an elliptical trace (Fig. 2, not shown) indicating dielectric loss without ionization and a rhomboidal trace (Fig. 3, not shown) indicating ionization plus dielectric loss. R3 is then switched in and adjusted to reduce the trace to an approximately straight line (Figs. 4, 5, not shown) and C3 is adjusted for coincidence with a predetermined straight line inscribed on the graticule having a slope determined by the amplitudes of the X and Y voltages at balance. The adjustments of R3, C3 may be calibrated in terms of capacitance and dielectric loss respectively, and the apparatus may be applied to testing insulation between conductor bars of dynamo-electric machines or of a cable which is immersed in conducting liquid or surrounded by a foilwrapping to provide the second electrode of a test capacitance. High-voltage insulators may be similarly tested. The loss angle # is given by 1 tan # = #-. #C3R3

Filed: 1937-06-04
Abstract: 496,881. Sorting cards, letters, &c. HITSCHMANN, E. June 4, 1937, No. 15501. [Class 117] Letters, cards, &c. are fed singly from a stack and are guided by rollers 3, 4, Fig. 1, and a pivoted guide member 9 to one or another of a series of shoots 5 which directs them into collecting receptacles according to visual characteristics. The guide 9 is moved by the armature 29 of a solenoid 28 acting against a spring 30 and the position of the guide is selectively adjusted by the interposition of blocks 31 of various sizes between the table 32 and a bar 26 carried by the armature of the solenoid. The blocks 31 are moved into position by keys 12, Fig. 2, acting through links 34 and toggle levers 35 and are returned by springs 36. The movement of each key may be arranged to close the circuit for energizing the solenoid and for actuating the card &c. feed devices, and a detent in the form of a rack-and-pawl may be provided to hold the guide 9 in position until the succeeding key actuation. The shoots 5 may be provided with ribs or wires and all incline in one direction, to reduce friction.

Title: Improvements relating to window operating mechanisms
IPC: E05F11/34
Filed: 1936-06-04
Abstract: 476,053. Operating-devices for flexible members in guides. COX, R. W. June 4, 1936, No. 15618. [Class 136 (i)] [Also in Group XXIV] Relates to window and windscreen operating mechanism of the type in which a unilaterally flexible member such as a chain or a metal strip issues from a guide to form a strut. According to the invention the guide is wholly or in part of curved form and the operating means engages the flexible member at one part only. The chain a, Fig. 1, is attached at one end to the wind-screen b and is movable along a guide c having a curved portion e and flanged edges d, Fig. 2, adapted to overlap the chain. Alternatively the guide may be a curved slotted tube.. For actuation, the flexible member carries a short notched projection f extending through the flanges d and engaged by a worm g of sufficient length to permit of the required movement of the flexible member. The worm may consist of a coiled wire on a spindle actuated by a handle h. In a modification, the flexible member consists of a cambered metal strip, and each end portion of the guide is straight. In a further modification the flexible member is actuated by a pin-and-slot connection with a lever adapted to be rotated by a worm and wheel. In a further modification, a pair of flexible members are actuated simultaneously in the same direction by being attached to a cross-bar having, e.g. a threaded connection with the actuating shaft g. In the modification, Fig. 9, the flexible members a are each slidably engaged by a lever s the other end of which is formed as a toothed sector t engaging a worm u on the actuating spindle v. In a still further modification, the guides extend along the lower edge and up the vertical sides of the wind-screen and the flexible members are connected flexibly to racks moved in opposite directions by a pinion on the actuating handle.

Abstract: 632,393. Photographic contact - printing frames. LITTLEJOHN & CO., Ltd., S. R., and COOPER, A. H. June 14, 1947, No. 15737. [Class 98 (ii)] A photographic contact-printing frame comprises a top glass frame and a bottom vacuum frame or blanket, the frames being geared together in counter-balancing relation. As shown, the top glass frame 3 and the bottom vacuum frame 4 are mounted on a framework formed of end members 1 and horizontal members 2.

Parallel to racks 6 and engaging the pinions 8 are racks 10 to the lower ends of which are secured or pivoted the bottom frame 4, the movements of the opposite pairs of racks being synchronized by chain- and-sprocket gearing to a common shaft 15. One of the pinions 8 is rotatable to open or close the frames by a hand wheel 11. A hand lever 21 operates, through rack-and-pinion gearing and a cross-shaft 25, bolts 16 at each side of the frame 4 to engage over rollers 22 on members depending from the upper frame 3 to lock the two frames together. The printing frame may be used in the horizontal position shown with the light-source above the frames, or may be used in the vertical position with the light-source disposed to one side. The racks 6 and 10 are mounted on the oppositely disposed quadrants 9, which may be looked in either the horizontal or vertical positions by spring-operated catches, controlled by a footlever 28, engaging in peripheral notches in the quadrants. The racks 6 carry pins slidable in arcuate grooves in plates secured to the frame 3, thus enabling the latter to be locked in any position between vertical and horizontal by nuts.

Abstract: 126,588. Schneider et Cie. April 19, 1918, [Convention date]. Field carriages; recoil apparatus.-Relates to endless-track gun carriages of the kind in which the trail A is trunnioned to a gun pedestal C vertically pivoted to a frame D supported on the trucks of the endless tracks G, and consists in making the frame D movable, round a shaft H, itself journaled in bearings I in the endless-track trucks E, the frame being further fixed to one of the trucks, as by arms D'. The endless tracks are therefore capable of turning independently of each other round the shaft H during firing or transport, whilst the truck fixed to the frame D provides a firm support for the gun carriage during firing. The invention is shown applied to a carriage which is trained round a pivot J<1> on the trail spade J by propelling the endless tracks at suitable relative speeds by a hand-operated ratchet-lever, Fig. 6, detachably applied to the squared end L' of a spindle L mounted to revolve within the hollow shaft H.
