Abstract: 1,103,722. Seaming non-metallic sheet material; laminates. DUNLOP RUBBER CO. Ltd. 13 May, 1965 [26 May, 1964], No. 21619/64. Headings B5K and B5N. An endless belt 1 comprises one or more reinforcement plies 2 embedded in a flexible material 3, the ends of the, or each, ply 2 being butted together and the ends 4, 5 of the ply 2, or the uppermost ply 2, being enclosed between the ends 6, 7, 8, 9 of a two-ply fabric 10 in which the two plies are interconnected along a line to form a fabric having an X-shaped section in a direction transverse to the line of interconnection. The fabric 10 may be two separate woven plies secured, e.g., by stitching, along a line transverse to either the warp or weft threads or, preferably, the two plies are woven simultaneously and either the warp or the weft threads of the two plies interchange between the plies at one point. A two-ply woven fabric may be produced having a series of lines of connection and the fabric 10 is severed therefrom. The fabric 10 may be cut on a bias. The fabric 10 may be made of natural or synthetic fibrous or filamentary material, e.g. polyesters, polyamides, rayon, cotton, polyvinyl alcohol or polypropylene, and has a covering of flexible material, e.g. natural or synthetic rubber or a polyvinyl chloride composition. The plies 2 may be made of steel cords or textile cords, e.g. of cotton, polyamide or polyester. The cords may be parallel to the longitudinal axis of the belt or at an angle to this axis of up to 40 degrees. Alternatively, the plies 2 may each comprise a woven textile fabric, e.g. a plain, twill, matt or leno weave, having warp or weft threads parallel to the longitudinal axis of the belt and may be made of cotton, polyamide or polyester fibres. Each ply 2 may comprise a multi-ply fabric and the ends of each ply are out at an angle of from 30 to 90 degrees to the longitudinal axis of the belt 1. As shown, six plies 2, each comprising a woven textile fabric in which the warp and weft threads are made of cotton yarn and nylon yarn doubled together, are embedded in a vulcanized rubber composition 3. The ends 4, 5 and 11, 12 of the upper and lower plies 2, respectively, are enclosed by the ends 6, 7, 8, 9 and 13, 14, 15, 16 of two-ply nylon fabrics 10, 17 respectively. To make the belt, the ends of a belt comprising six plies 2 are cut transverse to the belt at an angle of 40 degrees to the longitudinal axis thereof to produce complementary stepped ends which are then brought together. The fabrics 10, 17 each coated with a vulcanizable rubber composition are placed in position. The assembly is finally moulded under heat and pressure. A weaving plan for the fabrics 10, 17 is shown, Fig. 2 (not shown).

Title: Improvements in or relating to electronic reading systems for punched tapes or cards
Inventor: SAMAIN JACQUES
IPC: G06F7/22
Filed: 1953-08-06
Abstract: 735,821. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 6, 1953, No. 21723/53. Class 106 (1). An electronic card or tape reading apparatus comprises a plurality of sensing brushes arranged so that there is one brush for each hole in a column, an assembly of triode tubes, one for each group of hole positions in a column, a number of resistors in circuit with the grids of the tubes, changeable wiring connecting the grid resistors with selected brushes and a control element under the influence of the triode tubes. The arrangement is such that an impulse is directed to the element whenever a given punched hole combination is successively sensed as the columns pass under the brushes. Fig. 2 shows a conductive roll A and groups of brushes B11, B12, B13, G14, B15, connected by way of jumper connections to points G1, G2, G3, G4, G5 which are in the grid circuits of triode tubes L1, L2, L3, L4, L5. P1, P2, P3, P4 indicate four sources of voltage of decreasing value taken from a voltage-dividing network (not shown). Ra is an anode load resistor common to all the triodes, and T is a gas-filled triode or thyratron the blocking of which is controlled by the voltage existing on the terminals of resistor Ra while E is a control element for example a magnet or a relay to be actuated by the system. C represents a capacitor the value of which is such that the quantity of electricity it stores is sufficient to operate control element E when thyratron T is fired and Rb is a resistor charging the capacity C during the periods when the thyratron is non-conductive. The circuit described is employed where it is required to sense one number, where several numbers or words are required to be sensed a modification shown in Fig. 3 is used. In this arrangement each stage corresponds to a number to be detected. Both grids of the tube L11, for example, are connected to the two brushes corresponding to the required punched holes, in this case brush B11 is linked to G111 and brush B21 to G112. Thyratron T1 fires when both brushes sense a punched hole. B11 may alternatively be connected to G221 and B51 to G222, thyratron T2 then fires when brushes B11 and B51 both sense punched holes the control device E1, E2, &c., is then actuated in the manner previously described.

Title: Improvements in or relating to pump control
IPC: F04B1/08
Filed: 1954-07-28
Abstract: 758,297. Fluid-pressure servomotor-control systems. SUNDSTRAND MACHINE TOOL CO. July 28, 1954 [Aug. 10, 1953], No. 22041/54. Class 135. A control mechanism for a variable displacement pump 15 comprises displacement varying means, e.g., the swash plate 80 and means connecting it to an actuating device, e.g., the compound piston 60, having a first element 83 bearing on one side, and a second element 87 bearing on the opposite side, of the displacement varying means, and means, e.g. the two parts 70, 76 of the piston, urging the elements to move in opposite directions to clamp the displacement varying means between them. In the hydraulic transmission from the variable displacement multiplunger pump 15 rotated by gear 25, through multi-plunger motor 16, swash-plate 23 and shaft 24 to gear 26 the pump swash-plate 80 is adjusted by piston 60 under the control of a governor 33 responsive to the speed of gear 26. Aircraft engine lubricating pumps 35, 36 supply oil via passages 39, 42, 43 to a valve chamber located between the pump and motor for maintaining the plungers against the wobblers. The oil then passes to lubricating points 51 via passages 44, 46, 48 and reducing valve 49. Oil is also taken via pipes 53 to supply the governor 33 and provide the control pressure in pipes 31, 32. This pressure forces the two parts 70, 76 towards one another. The part 70 thus pushes the rod 83 into a socket on the wobbler 80 and the rod 87 which is pivoted to the skirt 78 of the part 76 is pulled by that part into a socket on the other side of the wobbler. The space between the elements is open to exhaust via passage 91.

Title: Improvements in or relating to aerials for use in wireless telegraphy and telephony
IPC: H01Q9/30
Filed: 1926-09-08
Abstract: 281,762. Franklin, C. S. Sept. 8, 1926. Aerials; directive signalling. - Impedances are inserted along the length of the aerial wire at points where the apparent resistance is equal to or lower than the surge impedance, so as to make the effective resistance equal to the surge impedance, and capacity or inductance is added to restore resonance. The combination may be utilized as a singlewire reflectionless feeder to a radiating system. Fig. 1 shows the effective resistance plotted vertically against horizontal lengths of wire for an aerial having a surge impedance of 400 ohms when energized on a wavelength of 86 feet. The points of low effective resistance occur at 20, 60 and 100 feet and correspond to one-quarter, threequarters, five-quarters &c. wavelengths. Fig. 4 shows a compensated aerial, with resistance R added to make the effective resistance equal to the surge impedance, and an inductance L or capacity C inserted to balance the reactance of the wire. Inductance coils N suppress radiation from alternate half wavelengths of the remaining length of aerial. Where the length of wire lying beyond the compensating elements is short, the arrangement approximates to an aerial of the Beverage or wave type but has the advantage that it may be erected vertically or at any desired angle, since no earth is necessary beyond the point of compensation. On the other hand the part of the wire beyond the point of compensation may be long and have large radiating power, in which case it can be erected at a considerable height above the ground with increased efficiency and reduced earth losses. The first part of the system then acts as a single-wire "feeder" to the second. The radiating portion may comprise impedances adapted to secure directional effects. As shown in Fig. 5, the part A may comprise a number of spaced wires, the effective resistance of which may be made equal to the surge impedance of the feeder wire W without the addition of special compensating impedances such as L, R, C. A number of such aerials may be employed, with or without reflecting systems, to secure directional effects.
