Abstract: 988,715. Hydraulic transmission. DOWTY TECHNICAL DEVELOPMENTS Ltd. Feb. 19, 1963 [Feb. 20, 1962], No. 6450/62. Heading F2C. In a hydrostatic transmission of the type wherein a hydraulically connected pump 6 and motor 7 each comprises a tiltable head 8 carrying a valve plate 15 and rotatable cylinder block 14 with axial cylinders which co-operate with pistons 21 connected to a non-tiltable plate 13 fast with a driving or driven shaft 12 carried by a bearing housing 11; the pump and motor heads 8 are connected by a single pivot 26 and the pump or motor bearing housing 11 is permitted axial or angular movement. As shown, the pump bearing housing 11 is axially slidable in guides 22, and the pump 6 is conditioned for zero displacement whilst the motor 7 is conditioned for maximum displacement. The plane through the pivot 26 and pivot 9 of the tiltable head 8 is perpendicular to the shaft 12 so that when the pump head 8 is tilted down or up for forward or reverse drive the motor head is tilted upwardly to reduce its displacement. The tilting movement of pump and motor heads may be effected by a servomotor (not shown), and leakage from the fluid system may be replaced by a make-up pump (not shown) driven by the input shaft 12. In Figs. 4-6 (not shown) the pump housing is angularly movable and in Figs. 7-10 (not shown) the motor bearing housing is angularly movable.

Title: Improvements relating to dry cleaning apparatus
IPC: D06F43/02
Filed: 1950-03-22
Abstract: <PICT:0689185/III/1> <PICT:0689185/III/2> In a dry-cleaning apparatus of the kind having a perforated drum 2 rotating in a casing 1 during the cleaning operation and subsequent removal of the solvent by centrifugal action and having also an air inlet 4 and an outlet 5 in the casing for the final deodorization of the cleaned articles, a false bottom 7 is provided between the drum and the casing extending over at least the width of the drum to form with the casing a part-annular duct 8 extending upwardly in both directions from the lowest point in the casing to conduct the liquid to a draining outlet 9 in the bottom of the casing.  The extracted liquid is thus prevented from circulating round and round the casing and being thrown out of the air inlet and air outlet.  Valved pipes 11, 12, conduct the solvent to a storage tank 15 or to a still 16.  A valved overflow outlet 17 in the duct 8 also leads to the storage tank 15 and maintains a constant level of liquid in the apparatus during the cleaning operation.  The solvent is supplied continuously by a pump during the cleaning operation.  After the latter the solvent is drained off and the drum then rotated at high speed, the pivoted shutter 6 in the air inlet 4 being closed.  In the final deodorizing stage, the pivoted shutter 6 is opened.  In a modification, curved walls 19, Fig. 4, are provided between the false bottom and the casing to deflect the liquid towards the draining outlet, the false bottom also being perforated at 20 to permit liquid dropped above it to drain into the draining outlet.

Abstract: 609,265. Eddy current brakes; bearings. WINTHER, M. P. March 9, 1946, No. 7430. Convention date, March 12, 1945. [Classes 12 (i) and 103 (i)] [Also in Group XIX] An eddy current dynamometer or brake comprises a concentric stator and rotor having flux concentrating poles peripherally spaced throughout an arc over only the upper portions of the stator extending from the stator towards the rotor and in close proximity thereto, and a field coil housed in a recess in the stator generating a flux field interlinking the stator and rotor through the poles, with perforated axial conduits located between the stator and rotor in an arc extending under the lower portions of the rotor to direct sheets of coolant liquid radially on to the surface of the latter. Several such dynamometers can be coupled together in alignment, the stators being also preferably connected together to actuate torquemeasuring apparatus. A motor can be readily coupled to drive them all for cleaning &c. purposes. The rockable stator S is mainly a welded construction with end heads 49 bolted thereto carrying bearing necks 27. The head 49 supports a labyrinth assembly 57 to which compressed air is supplied from a pipe 61, and a rotor sleeve bearing 53 having a drain pipe 62 for excess oil. The body of the stator comprises an outer cylinder 65, two end rings 67 and a series of inner cylinders such as 68, 70, connected together by recess-forming rings 71, 73. In each recess is a peripherally-wound field coil 77 sealed by non-magnetic rings 75. Magnetic teeth 81, 83 are welded to the top arcuate portions of the rings 68, 70, respectively, their ends 85 extending under the coils 77. The teeth 81 are of opposite polarity to the teeth 83. The lower arcuate portions of the rings 68, 70 have bridge plates 117 perforated to carry non-magnetic water tubes 121 which are slit axially to allow water to spray against the rotor R. A single water tube 129 is also supported between the teeth 81, 83 above the rotor. All the tubes are secured at the ends in header rings having access to end headers 95 supplied with water by flexible pipe 99. Outlets 115 connected to flexible pipes 113 allow the water to drain from the stator to a sump in the base-plate 1 of the machine. The water feed pipes for the right-hand header 95 are supported on the left-hand pedestal 3, and the pipes for the left-hand header are supported on the righthand pedestal. The stator S of each dynamometer has opposite pads to receive torquemeasuring apparatus if necessary, and end pads are provided whereby all the stators can be connected to actuate a single torquemeasuring means. Bearings.-The bearing necks 27 are mounted in the inner races of roller bearings, the outer races of which are carried by a ring gear 19 which is slowly rotated by a motor operating through sprocket gearing to drive a pinion meshing with the ring gear 19. This arrangement ensures an even wear of the bearings.
