Inventor: KILLION DAVID L
IPC: F04B23/12
Filed: 2008-05-02
Abstract: A variable nozzle area jet pump is provided having a nozzle-sealing member resiliently urged to form a sealing closure. The sealing member is part of a normally non-passing pressure control valve that recirculates excess fluid back to the inlet of a positive displacement fluid pump. The fluid is recirculated with elevated pressure after a threshold fluid pressure is exceeded. The disclosed system provides for energy conservation and pump cavitation speed increase. The system may be integrated with an engine balance shaft module so as to provide low cost robustness to low speed gear noise emissions by application of the oil pump's drive torque to at lease one gearset.

Abstract: 108,007. Vickers, Ltd., and Elia, G. E. July 14, 1916. Mines, marine.-Relates to mines which are automatically anchored at a given depth by being made to sink with the anchor to the bottom and then to rise from the anchor until stopped at the desired depth. According to the invention, a weight, normally attached to the mooring cable, is released by a hydrostat as the mine rises, and the fall of the weignt causes the paying out of the anchoring cable to be stopped. ln the form shown in Fig. 5, the drum E of the anchor B is released to allow the mine A to rise by a spring pawl G when this is relieved of the pull of a weight C just before the anchor touches bottom. A hydrostat H and a weight I are attached near the mine to the mooring cable, D by means of a tube 2, fig. 6. The weight when released by the hydrostat falls along the cable and strikes a pivoted arm J; the shock on this arm is transmitted by a finger 24 to a pawl 26, which overcomes a spring catch and locks the drum E. The weight I is normally held in place by ai lever 11 locked by another lever 8, which is pivoted at 9 and is subjected to the action of two springs 7, 14 and of the water pressure on the left of a diaphragm 5. The spring 14 is finely adjusted by a screw-cap 15. To prevent premature release of the weight, the lever 8 is locked by a bolt 19, which is removed by a line 21 attached to the anchor when the mine rises from the anchor, a small wire 20 holding the bolt in place being easily sheared by the pull of the line 21.
