Title: Improvements in or relating to hydraulic reciprocating pumps or motors
IPC: F01B3/00
Filed: 1960-05-23
Abstract: 890,604. Reciprocating pumps. THOMA, H. May 23, 1960 [June 18, 1959], No. 18092/60. Class 102(1). [Also in Group XXIX] In a hydraulic pump or motor having a plurality of pistons slidable in bores which may be parallel, inclined or radially disposed with respect to each other, liquid is conveyed under pressure under the control of automatically operating valve means to areas between each piston and its bore to oppose, and resist the side thrust imposed on each piston through the drive or transmission means. As shown in Fig. 1, each piston 1 slidable in its bore in a rotatable cylinder barrel 2 and formed with a spherical end 7 co-operable with a shoe 13 bearing on a driving disc, is formed with an axial-bore 5 in which is fitted a pin 8. The pin has an axial bore (not shown), and helical grooves or flutings 18 having a twist through 180 degrees. With the shoe 15 in its central position with respect to the piston 1, the flutings 18 are sealed. On the shoe being inclined with respect to the piston liquid fromthe pumping chamber passes up through the bore of the pin 8 into a shoe recess 14 and thence is directed down a fluting to a radial piston port 15 connected with a recess 15<SP>1</SP> to be discharged to act on that side of the piston to relieve the lateral piston thrust. A lower contact pressure may occur farther down the piston, to counteract this the flutings are extended to co-operate with additional radial ports 16 and a recess 16<SP>1</SP>. To prevent the entrance of dirt into the flutings the liquid passes through a clearance between the piston and bore and radial piston ducts 10 aligned with radial pin ducts (not shown). In a modification, a shortened pin 8, Fig. 5, has a plurality of longitudinal flutings 18 and control holes 24 communicating with an annular groove 26 connected by bores 27 to a shoe recess 29. Throttlling grooves 20 relieve the inner end of the piston. A lower annular piston recess 22 is relieved and the atmosphere through a bore 23. The flutings or helical grooves may be in the piston bore instead of the piston.

Abstract: 1,000,800. Suction lifting devices. MASCHINENFABRIK HASENCLEVER A.G. May 1, 1964 [May 21, 1963], No. 18106/64. Heading B8H. An article G, Fig. 1, is released from a suction lifting device, comprising a piston 2 moved in a cylinder 1 by a rod 3, by a manually operated valve 9 which admits air through a conduit 11 and a port 12 to the underside of the piston. In a second embodiment, Fig. 3, not shown, the piston is raised by a subsidiary piston at the upper end of the piston-rod which is moved in a cylinder by compressed air. The construction is otherwise as described above. In a third embodiment, Fig. 2, raising a piston rod 3 seals a valve head 13 against a loose piston 2 and moves the piston upwards to produce suction, upward movement of the piston being permitted by an annular rack 14 with grooves 16 which pass a key 15. This rack is rotated by a pawl 18 during the last part of the piston-rod's downward movement which takes place after the loose piston has come to rest. The amount of rotation is such that there is no groove 16 opposite the key 15, therefore, next time the piston-rod is raised no suction is produced and the device is raised bodily away from the load. When the device is set down on top of a further load the rack is rotated to bring the next groove 16 opposite the key so that lifting suction can be developed. A suction gauge calibrated in units of weight may be fitted.

[Class 40 (iv).] In a system of single side-band radio transmission, speech currents with all their frequency components equally displaced in phase are required at the transformers T1, T2. This phase displacement is effected without the use of balanced modulators by first modulating a carrier D1 by the valves M1, a, selecting a single side-band by the filter F, and then de-modulating this side-band by combining it in the valve d with the same carrier D1 displaced the required angle (say 90) in phase. The side-band filter F may comprise an artificial line L, R, Fig. 2, coupled at various points through tuned circuits to the input circuit of a valve V. By suitable tuning of these circuits all the frequencies passed by the filter will have approximately the same displacement in phase. The tuned circuits may be directly connected to tappings on the line L, and resistances r can be inserted in the grid circuit of the valve or in the tapping-leads, Figs. 4 and 5 (not shown).
