A rotary pump or motor has a rotor 11 with outwardly sliding vanes 14 extending to a housing ring 1 through an annular working chamber 16 subdivided by abutments 4 and sealed laterally by packing rings 17 each of which is carried on a piston 18 urged axially by springs 29 and by the pressure of leakage fluid in chamber 20. The leakage fluid escapes through a passage 21 and either valves 22, 23 or an hydraulic motor driving e.g. an oil cooler fan. The abutments 4, four in number as described, are urged against the rotor by springs 10 and fluid pressure either from the working chamber 16 through a passage 7 or from an external source through a passage 9. The rotor has a curved outer periphery (shown at the bottom of Fig. 1) and is fixed to rings 13 connected to the shaft 26 by splines 27. Four alterantive methods of withdrawing the vanes to clear the abutments are shown in Fig. 1:-(a) a cam track 32 engages a piston 31 separated by a space 52, filled with hydraulic fluid and preferably steel, balls, from a smaller piston on which is mounted an arm connected to a vane; (b) a ball 38 in a cammed slot 32a is mounted on a lever 35; (c) a roller 43 (Fig. 2) engages a cam track 32 and moves a plunger 39; (d) a roller 46 pivots a lever 48.

Abstract: 1,248,573. Deflecting propulsion jets. ROLLS-ROYCE Ltd. 16 Oct., 1968 [18 Oct., 1967], No. 47407/67. Headings B7G and B7V. [Also in Division F2] A thrust producing means for propelling rockets, or, air water and underwater craft, comprises a tubular housing 1 with a curved bearing surface 2 providing a seating for a complementary surface on a nozzle 3. During operation a pressurized sealing fluid is introduced between the surfaces by a series of circumferentially spaced radial passages 5 fed by a duct 7. An annular seal 4 extends around the bearing surface between the downstream end thereof and the ports 6 of the passages 5. An annular driving ring 8 rotatable by means of gear teeth 10, engages an arm 11 on nozzle 3 for rotating the nozzle about the housing's axis and the ring 8 also carries an actuator 12 to tilt the nozzle. Alternatively, universal swivelling can be achieved by two double acting actuators connected to the nozzle at 90 degrees with respect to each other. The pressurizing fluid, which lubricates, cools, and seals the bearings against leakage, may be a propellant for a combustion chamber of a rocket engine; the flow of sealing fluid being synchronized with the engine firing sequence.

Abstract: 1435788 Seismic energy generators GEOSOURCE Inc 19 Oct 1973 48921/73 Heading H4D  A method for generating an underwater seismic pulse having a signature with a primaryto-secondary pulse pressure ratio of at least eight-to-one comprises spacing a plurality of bubble-generating seismic energy sources of different sizes apart sufficiently to prevent coalescence of their initially expanding bubbles of correspondingly different maximum diameters, actuating the sources simultaneously, and suppressing secondary oscillations of the bubble of at least one source.  In one embodiment, seven air guns of different chamber volumes and mutually spaced at various intervals are supported by floats and towed by a ship. Each gun has two compressedair chambers connected by an orifice, one chamber serving to inject oscillation-suppressing air into the bubble generated by abrupt release of air from the other chamber. Delays been a firing control signal for the guns and their actual firing times are compensated for by electronic means, the delays for individual guns being measured with the aid of respective hydrophones placed near the guns. The guns may be replaced with explosive or other seismic sources. Bubble oscillation may be suppressed by other gas-injection techniques or by using a perforated enclosure for the seismic source.

Abstract: 1,069,990. Inductive heating of crankshafts. INTERNATIONAL HARVESTER CO. Dec. 13, 1963 [Dec. 26, 1962], No. 49292/63. Heading H5H. The journals of a crank-shaft are heated for case hardening by an inductor 71 embracing an arc of some 120 degrees which rests on each bearing in turn and is constrained to follow their movements as the crank-shaft is rotated. In the case of the pin journals the heating power is switched between two levels at predetermined angular positions of the shaft to compensate for the effect of the webs: The inductor is suspended from parallelogram arms 64 which are themselves carried by a second set of arms 55, 56, one of which has strikers 87, 88 to actuate switches 83, 84 whose position on an arcuate plate 90 is adjustable. These switches, together with a second pair on the opposite side of support bracket 52, control the heating cycle, which consists in energizing the field circuit of a generator supplying the inductor through selected rheostats and for a total time determined by timing motors. When main journals are being heated there is no up and down movement of the inductor to actuate the switches and thus a constant heat is applied as is necessary in this case. The inductor supporting assembly is mounted on a carriage 30 manually moved along rails 28, 29 and is accurately located longitudinally of the crankshaft by an indent plate 35 which is engaged by a hand wheel operated pawl. Different inductor heads 71 are used for the various journals and the act of inserting them in channels 66 operates interlock switches 74 which, together with further switches on the indent plate, ensure that the correct inductor is used for each bearing and also that the appropriate field rheostat is switched into the generator field circuit. The apparatus is mounted on a quench tank 10.
