Title: Improvements in or relating to rotary hydraulic pumps and motors
IPC: F04C2/36
Filed: 1964-03-23
Abstract: 1,063,953. Hydraulic rotary pomps and motors. O. BJORNDAL. March 23, 1964 [March 30, 1963], No. 12176/64. Heading F1F. A rotary pump or motor for use in hydraulic transmission systems, comprises a two-part housing 10,11, Fig. 1, rotatably mounting first and second parallel shafts 14, 18, to which are keyed axially-spaced rotors 20, 22 driven in opposite directions through gears 16, 17 and sealingly rotating in chambers 24, 25 which overlap each other at 26. The rotor 20 is formed with diametrically opposite segments (29), (30), Fig. 2 (not shown) projecting axially from the rotor towards the rotor 22 whilst the rotor 22 is formed with similar segments (31), (32) projecting axially towards the rotor 20 so that they co-operate with each other to transfer liquid from an inlet (27) to an outlet (28). The rotors 20, 22 are mounted between thrust bearings 21, 23 respectively and each rotor is provided with ducts 34 located between the segments to connect recesses 33 behind the rotors to hydraulically balance the rotors against axial thrust. Liquid discharged from the system passes into the housing through an opening 41 and through ducts 41a in the shafts 14, 18 to lubricate the thrust bearings and roller bearings, 13, 19 bearingly supporting the shafts. The number of segments on the rotors may be increased. In another embodiment, there are three rotors instead of two whereby by suitable connection of the two inlets and two outlets the two pumps or motors may be connected in series or parallel.

Title: Improvements in or relating to circuit arrangements embodying electron discharge devices
Inventor: BARFORD NORMAN CHARLES
IPC: H01J29/58
Filed: 1952-05-15
Abstract: 755,013. Electron beam apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 14, 1953 [May 15, 1952], No. 12263/52. Class 39 (1). In electron guns adapted to work when immersed in a homogeneous axial magnetic field undesired rotational components are set up by reason of the fact that the beam is initially convergent and thus the electrons travel at an angle to the magnetic lines of force; these components are stated to be counteracted by reducing the intensity of the magnetic field locally in the region between the cathode 1 and the limiter electrode 2. This may be done by winding a counter-field-producing coil 4, Fig. 1, on the cathode or by making the limiter electrode itself of high-permeability material so as partially to screen the cathode-limiter region, Fig. 2 (not shown).

Abstract: 417,677. Reels &c. JERVIS, J. E., 280, Tamworth Road, Long Eaton, near Nottingham. April 27, 1933, No. 12282. [Class 120 (iii).] A reel of the type having a tubular hub and flanges secured thereto by retaining members disposed within the hub, has a plurality of rigid tubular metal stays which extend longitudinally inside the tubular hub and through the flanges and have their ends bent over or flanged, preferably within the thickness of the spool flanges, internal means separate from the hub being provided to hold the flanges apart. The flanges 1, e.g. of plywood, are secured to the cardboard hub 2 by retaining members 4, preferably split tubes, having their ends splayed or beaded over as at 7, and tightly pressed into countersunk holes in the flanges. Each tube 4 may be formed with a shoulder or rib to bear against the inner face of the flange, or one or more ears may be bent outwards from the tubes for the same purpose, or the tubes may be surrounded by distance sleeves 9, e.g. of wood.

Title: Improvements in and relating to moving coil voltage regulators
IPC: H01F29/12
Filed: 1934-04-24
Abstract: 438,791. Transformers. FERRANTI, Ltd., and NORRIS, E. D. T., Hollinwood, Lancashire. April 24, 1934, No. 12374. [Class 38 (ii)] Relates to a voltage regulator comprising two fixed coaxial windings 2, 3, connected in series opposition and displaced axially and a movable short-circuited winding 4 associated therewith and consists in disposing the windings such that when the short-circuited winding is in the centre position the sum of the leakage impedances between the fixed and shortcircuited windings is less than the leakage impedance between the fixed windings, so as to reduce the mid-position load impedance of the regulator. This is effected by making the axial distance between the two fixed windings less than the axial length of the shortcircuited winding. The invention may be applied to the form of voltage regulators described in Specifications 340,538, 341,903, 368,142, 368,592, 372,493, 394,063, 396,408, and 406,830.

Abstract: 749,219. Pipe joints; stopping pipes. LAURENT, M. P. April 28, 1954, No. 12385/54. Class 99(1). A joint between two members e.g. pipes 8, 9, Fig. 2, at least one of which carries a fluid under pressure, comprises opposed conoidal sealing surfaces 13a, 14a, and a sealing ring 15a of substantially rigid material, e.g. metal, bridging the interval therebetween, the inner edge of the ring being subjected to the said fluid pressure and the relation between the surfaces 13a, 14a, being such that the outer surface 13a conforms substantially to an imaginary surface generated by the periphery of the ring 15a when the latter is forced towards the wider end of the surface 14a; alternatively the surfaces 13a, 14a may be such that the interval therebetween has substantially constant cross-section in planes normal to their axis, or the ring 15a and the interval between the surfaces 13a, 14a, may be defined as conforming to an imaginary solid generated by rolling a torus of constant volume over the surface 14a. The surfaces 13a, 14a, may be conical or, as shown in Fig. 2, the surface 14a is a portion of a sphere centred on the axis of the pipes 8, 9, at C, the surface 13a being conical and a close approximation to the surface obtained by the definitions given above. The space behind the ring 15a may be closed by rubber packing rings 16, 17, Fig. 3, which transmit the fluid pressure to the ring 15a. In Fig. 4 the two pipe ends are formed with identical spigots having the curved sealing surfaces 14b which co-operate with conical sealing surfaces 13b on a separate ring 18 and with sealing rings 15b, a rubber packing ring 17b filling the gap between the rings 15b and pipe ends. In a modification the spigot surfaces 14b are formed on the ring 18 which engages in identical sockets in the pipe ends. An application of the invention to a return bend is described and in Fig. 8 the sealing ring 15a seals the joint between an access plug 34 and its seat in a box-type return bend. U.S.A. Specification 2,582,995 is referred to.

Class 139 In a time delay mechanism a toothed member 12, Fig. 2, meshes with a pinion 16 to drive a gear train controlled by an escapement (not shown). The member 12 is rotated by an operating lever fixed to a disc on a bush of the member 12 so that when the member 12 leaves the pinion 16 the disc quickly completes its travel. During reverse setting movement of the member 12 the end of the spindle 15, Fig. 3, of the pinion 16 rides up a slot 14 in the frame plate 3 to disengage the pinion from the member 12. In a modification the operating lever and disc are replaced by a toothed rack which meshes with a gear fixed to the member 12. The angular position of the rack may be adjustable. The member 12 may be replaced by a gear which meshes with a mutilated rack. The spindle 15 may be tilted to disengage the pinion 16 from the member 12 by a cam member operated by a push button, Fig. 7 (not shown).
