Title: Hydrostatic power systems
IPC: F04B1/20
Filed: 1970-05-07
Abstract: 1312275 Hydrostatic transmission ROBERT BOSCH GmbH 7 May 1970 [10 May 1969] 21980/70 Heading F2C [Also in Division F1] A power unit operable as a pump, motor or hydrostatic transmission comprises at least two machines 2, 55 each operable as a pump or motor, mounted in a common housing and having their rotating parts connected by releasable coupling means. In the axial piston machine arrangement shown, the rotary cylinder blocks have meshing gears, one gear 26 being axially movable by fork 43 for releasably engaging the other gear. Valves 63 and 67 are operable in conjunction with fork 43 to hydraulically connect the machines so that, with the gears engaged, either single or double pump or motor operation is obtained, and with the gears disengaged, the machines operate in a closed circuit as a hydrostatic transmission, clutch 60 also being operated with fork 43 to couple shaft 56 to output shaft 59. When operating as a transmission, pump 70 makes up leakage losses. In Fig. 8 (not shown), forward and reverse rotation of the transmission output shaft is provided by reversing the inclination of the pump swash-plate, check valves being provided in lines connecting the make-up pump to the high and low pressure connecting lines of the transmission. The coupling gears alternatively may be provided on the cylinder block drive-shafts, together with synchronizing means, Fig. 11 (not shown). In Fig. 2 (not shown), the cylinder blocks are fixed and the swash-plates rotate, the coupling gears being mounted on the swash-plates. The axially movable gear arrangement may be replaced by a gear movable into and out of mesh with gears on the rotating parts of the pumps or motors, Fig. 9 (not shown). The axial piston pumps or motors may be replaced by radial piston pumps or motors. In Fig. 10 (not shown), three pumps or motors are arranged in a common housing, two of them having driveshafts, and a coupling means being provided for operation as a transmission with auxiliary pump, a double pump or motor, or a single pump or motor. Belt or chain drives may replace the coupling gears.

IPC: E02F7/10
Filed: 1958-07-09
Abstract: 893,167. Suction dredgers; hydraulic jetting. WATANABE, H. July 9, 1958, No. 22004/58. Class 68(1). The exit from a suction pipe 17 enters a delivery pipe 16 on the exit side of a restriction in the delivery pipe so that the vacuum created on the delivery side of the restriction by water being pumped through the restriction causes particulate matter, which has been agitated into a liquid suspension by liquid jetted from a conduit 18 extending from the delivery pipe 16 from before the restriction to adjacent but not surrounding the intake of the suction pipe, to be drawn up through the suction pipe and passed along the delivery pipe. This system may be incorporated in the base of a hollow pile, which is then sunk into position by the combined jetting and suction action of the system.

Abstract: 731,843. Spray burners. LANGHAM, A. J. Dec. 2, 1953 [Sept. 3, 1952], No. 22189/52. Class 75 (1). An air straightener unit adapted to be disposed in a draught tube 15 coaxially surrounding a burner atomizing nozzle 28 comprises two or more coaxial tubes 1a, 2a, 2b and a plurality of transverse vanes 3a supporting the tubes coaxially within the draught tube upstream of the nozzle so as, to define a plurality of coaxial air passages. The vanes have slotted engagement with the coaxial tubes and are disposed in two sets, one at each end of the unit as shown or in a single set at one end. The vanes extend over a minor portion of the length of the unit and the latter is not less than five times the radial thickness of the passages between the tubes. The inner ends of the vanes may extend inwardly of the innermost tube and their outer ends extend beyond the outermost tube and are cranked to engage resiliently the internal wall of the draught tube. An air swirler unit is disposed in the draught tube downstream from the straightener unit and comprises a hub 5 and radial vanes 6 extending therefrom to a frusto-conical band 9. The vanes extend axially beyond the band 9 and the extended portions 10 are curved to rotate the air. The curvature of the extended portions 10 may be such that the outer air is given a greater or smaller rotation than the inner air or that the outer air is given a rotation opposite to that of the inner air. The hub 5 is in the form of a sleeve adapted to fit around an oil supply pipe and in the embodiment shown its ends are closed by streamlined plugs 5a. The swirler unit is located within an air constricter cone 11 the wide upstream end of which has spring tongues for engaging the inner wall of the draught tube and the narrow end of which has a flange 14 supporting the cone coaxially within the draught tube. The draught tube has an aperture 38 which allows removal of the straightener unit, the swirler unit and the constrictor cone and which is covered by a plate 37 clamped to the draught tube by a bracket 40 secured by nut 42 on a stud 43. The outlet end of the draught tube is fitted with a convergent divergent throat ring 24 of internal diameter not less than that of the narrow end of the constrictor cone. The ring may be formed in two parts, the outer part having deflector blades 27. The burner nozzle is supported immediately downstream of the constriction of the throat ring 24 by a ring 35 carried by arms journalled in the throat ring. Specifications 658,619 and 682,446, [Group XXIX], are referred to.

W.; 1161, Lowell Road, Schenectady, New York, U.S.A.) Aug. 6, 1931, No. 22296. Convention date, Aug. 27, 1930. [Classes 39 (i) and 40 (v).] In generating oscillations of short wavelengths of the order of a few cms., electrons from a cathode 4 pass an anode 6 and are received by a third electrode 5 beyond the anode 6 and at a positive potential less than that of the anode so that secondary emission from the electrode 5 to the anode gives the circuit of the electrode 5 a negative resistance to generate oscillations in a tuned structure 10 wholly or partly in the valve envelope 1. The structure 10 has a plate 12 forming with the plate surface of the electrode 5 a capacity resonating at the frequency of the oscillations with the inductance of a wire 13 at right-angles to, and connecting,. the surfaces 5, 12. The structure 10 also has a tubular part 11 forming a capacity counterpoise with sufficient capacity to ground to prevent rapid variations of the potential of the structure 10. The anode 6 is annular and the cathode 4 is surrounded by a focusing cylinder. The parts 11, 12 may be outside the envelope 1 about the stem 3. The wire 13 may be coiled and the electrode surface 5 may be reduced in size to the cross section of the wire 13 and formed by the end of the wire. The oscillations may be modulated by a grid between the electrodes 4, 6 and are radiated by the parts 5, 13.
