Abstract: 365,291. Belt gearing. FREEDLANDER, A. L., 522, Grand Avenue, Dayton, Ohio, U.S.A. Dec. 30, 1930, No. 39187. [Class 80 (i).] A V-grooved pulley is used with a trapezoidal belt so formed that only its lower side edges engage the side walls of the pulley either in a continuous line or in a succession of points. At the bottom edge of the belt is situated a section of very heavy fabric 1 cut on the bias, which is surfaced by a rubber skim 5. Such fabric is substantially rigid transversely to the belt length but flexible longitudinally, and its raw edges engage the pulley when the rubber skim wears away in use. Above this section is a layer 6 of compressible material consisting of fine fibres mixed with rubber. Adjacent this section is an inextensible section 7 of rubberized cords wound continuously into several layers. An extensible section of continuously wound layers of light fabric 8 embedded in rubber completes the belt, which is pre-stretched during manufacture and vulcanized in that condition. The inner face of the belt may be corrugated, in which case the pulley is engaged in a succession of points. The belt may taper from its inner face towards its periphery.

Abstract: 344,574. Raising liquids by compressed air. THOMPSON BROS. (BILSTON), Ltd., THOMPSON, F. S., THOMPSON, H. J. and MEREDITH, J. W., Bradley Engineering Works, Bilston, Staffordshire. Dec. 27, 1929, No. 39565. [Class 102 (ii).] A device for raising liquids by compressed air has two chambers A, A<1> to which the liquid flows from pipes B, B<1>. The valve E admits compressed air first to chamber A<1>, the air pressure keeping vent valve H<1> on its seating. When the chamber is nearly empty the float N<1> rests on stop P<4> and opens the valve H<1> through the lever J<1> thus venting the chamber. This loss of pressure causes valve E to shift and close chamber A<1>, and hence the air then empties the chamber A through its discharge pipe R.

Title: Improvements in or relating to hydrodynamic transmissions
IPC: F16H61/64
Filed: 1963-10-10
Abstract: 987,624. Hydraulic couplings and converters. F.A.E. PORSCHE. Oct. 10, 1963 [Nov. 2, 1962], No. 39956/63. Heading F2C. An hydrodynamic torque converter or a fluid coupling for a motor car &c. is provided with a make-up pump mounted directly between two of its pump &c. elements. As shown, an engine crank-shaft 1 is splined to the bladed pump 8 of an hydrodynamic torque converter having the outer toothed ring 26 of a make-up gear pump 25 secured in a ring-shaped recess at its end. An inner toothed ring 27 of the gear pump 25 is held eccentrically with reference to the axis of the torque converter by a crescent-shaped filler element 28 secured to the bladed reactor 15, 16 of the torque converter, the teeth 32, 33 of the two rings of the gear pump meshing. The reactor 15, 16 is supported through a one-way detent 18 on a fixed tube 19. On starting, the torque converter pump 8 rotates and takes with it the outer gear pump ring 26, which in turn drives the inner gear pump ring 27. The crescent-shaped filler 28 on the reactor 15, 16 is held stationary by the one-way detent 18, so that a low-pressure zone 40 is created within the gear pump 25, to draw in oil from the sump (not shown) of the torque Converter through passages 38, 37, 39. The gaps between the teeth 32, 33 of the ring gear pump 25 passing on each side of the filler element 28 carry oil round to a high-pressure zone 41, connected through a port 42 with the torque converter working space. Excessive build-up of pressure is prevented by oil passing through a passage 43 between the torque converter pump and a bladed torque converter turbine 9 to a spring- closed relief valve 44. The turbine 9 drives to a change-speed planetary gear 13 (not further described). With sufficient increase in speed of the turbine 9, 8 as drive is taken up, the coupling point is reached, and the reactor 15, 16 begins to rotate forwardly, as permitted by the one-way detent 18. The crescent-shaped filler element 28 carried on the reactor 15, 16 accordingly begins to rotate with the toothed rings 26, 27 of the gear pump 25, reducing the output of the latter. Slippage between the pump and turbine 8, 9 of the converter keeps the gear pump 25 sufficiently operative to maintain a small flow of oil from the sump to make-up for leakage.
