Abstract: 1,146,840. Hydraulic couplings. SOC. ANON. FRANCAISE DU FERODO. 2 Aug., 1966 [5 Aug., 1965], No. 34629/66. Heading F2C. In an hydraulic coupling the inner ends of the radial vanes 14 of the pump element are connected to an axially tapered deflector ring 21, an annular gap 24 being formed between the ring and the interior of the pump casing 10. At low speeds, as at starting, the bulk of the working fluid occupies an interior compartment 22 so that the torque transmitted is low, but as speed increases the ring 21 acts to promote outward flow of fluid through the gap 24 into the working circuit. The width of the gap 24 should not exceed half that of the ring 21. As shown, the ring 21 is of trapezoidal section, but other tapered forms are described, together with arrangements in which the ring is combined with internal webs.

Title: Improvements in or relating to cash registers and similar accounting machines
IPC: G06C11/02
Filed: 1931-12-17
Abstract: 393,989. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Robertson, W. H.; 1302, Patterson Road, Dayton, Ohio, U.S.A.) Dec. 17, 1931, No. 34928. Convention date, Dec.17, 1930. [Class 106 (i).] The amount indicators of a cash register or similar accounting machine are obscured by a shutter during a total or subtotal taking operation, means being provided to retain the shutter in obscuring position until the total indication is removed from the indicators by a subsequent operation of the machine. The shutter 100 is carried by a frame 96 rockable about the indicator shaft 97 and pin-and-slot connected to a lever 90. When the total control lever 75 is moved to a total or subtotal taking position, a bell-crank lever 83, connected to the lever by a link 85, is rocked clockwise, and a stud 86 thereon co-operates with the cam-shaped end 91 of the lever 90 to move the shutter into obscuring position. The shutter is held in obscuring position by the abutment of a stud 114 on the lever 90 with a step 113 on the upper arm of a latching lever 107. During each subsequent operation, the latching lever is disabled by a rocker 121 operated by the differential mechanism, and the shutter is restored to non- obscuring position during the machine operation that follows the return of the total lever. While the shutter is in obscuring position, the printing hammer 77 for the voucher is disabled by a slide 104 connected to the lever 90. The Specification as open to inspection under Sect. 91 describes the application of the invention to a machine of the type described in Specifications 285,500 and 318,252, [both in Class 106 (i), Calculating &c.]. This subjectmatter does not appear in the Specification as accepted.

Title: Electrical line circuit

Abstract: 963,286. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Dec. 1, 1960], No. 35246/61. Heading H4K. In a system in which a gate T is used to establish connection between one end of the secondary winding of a transformer TR1 in a subscriber's line circuit and the rest of the exchange, the other end of the winding being connected to a common return path, the latter is earthed only at some central point in the exchange, and is connected via a high pass filter (condenser C6) to the control circuit for the gate T. The circuit is also provided with clamping diodes D4, D5 to prevent damage to the transistor gate T when the subscriber goes off- or on-hook. As shown communication is established by the " resonant transfer " method between the condenser combination C5, C3, C4 and a corresponding combination in another subscriber's line circuit by synchronously opening symmetrical transistor gates T in the line circuits and at such highway interconnections as are necessary. These condensers also form part of the usual low-pass filter which is here of the m-derived type. Transistor T is normally biased off by potential applied over decoupling inductance L3 and the right-hand coil of transformer TR2. Such transformers are arranged in a 10 X 10 array. The left-hand coil of the transformer is normally short-circuited by a transistor common to a row, the windings of which are connected in parallel. The centre windings of a column are connected in series and are normally energized through a conducting transistor. When gate T is to be opened the requisite pulse is provided by opening both the row and the column transistors condenser C6 providing a path for the current pulse. The limiting diodes D4, D5 keep the left-hand emitter of transistor T within voltage limits determined by the Zener diodes Z1, Z2. Since the highway may assume a standing D.C. bias due to the control currents fed to the numerous gates connected thereto, Z1 and Z2 may require to have different break-down voltages. Specification 824,221 is referred to.
