Title: Improvements in or relating to multiple pumps
Inventor: MURRAY JOHN F
IPC: F04D13/12
Filed: 1954-08-05
Abstract: 768,664. Gear pumps; centrifugal pumps. THOMPSON PRODUCTS, Inc. Aug. 5, 1954, No. 2303/56. Divided out of 768,663. Classes 110 (1) and 110 (2). A multiple gear pump, Fig. 1, incorporates a centrifugal impeller 107 which pumps fluid from the inlet 106 to the pumping cavities 103, 104 and is driven at a speed higher than that of the gear pumps through a gear train 121, 126. Movable bushings 129 are loaded by fluid fed to chambers 134 and are provided with lubricant recesses 142, 143, 146, each passage 146 incorporating a valve comprising a restriction orifice controlled by a spring-loaded ball, see Fig. 4 (not shown). The lubricant return passages 162 in the bearing surfaces of the housing 101 are also provided with valves 148; for details of said passages, Fig. 3 (not shown) should be referred to. The discharge pressure may be bled across the members 129 to the inlet side of the pump by a groove 165, see Fig. 3 (not shown), a secondary groove 163 connected to a source of high pressure being also provided. The output of the pump is fed to a flow control unit 178 and hence to burners 179, a by-pass conduit 186 being provided between the chamber 102 and the chambers 103, 104. The centrifugal impeller is preferably designed to produce a discharge greater than the combined capacity of the gear pumps and in a modified arrangement, see Fig. 6, a proportioned amount of the discharge from the impeller is metered through restrictions 191, 192 in a passage 190, said restrictions communicating with the bearing surfaces as shown.

Title: Improvements in phonographic sound reproducing devices
IPC: G11B33/06
Filed: 1939-01-23
Abstract: 513,198. Spring motors. FRANCK, E. W., and REEVES, H. E. Jan. 23, 1939, No. 2325. [Class 10] [Also in Group XXXVIII] Relates to sound reproducing machines, particularly adapted for use in dolls, and consists in providing as the driving motor a spring motor having a winding key which controls the starting and stopping, starting being prevented until the key has been moved from the winding position. The driving spring 31, Fig. 5, anchored at 24, is attached to a spindle 33, which is geared through pawl and ratchet mechanism to the turntable spindle 46 and to a governor 54. The spindle 30 has a pin 89 which abuts against one side or the other of a stop screw 88 when the spring is either wound or' unwound. The parts 88, 89 thus positively limit the movements of rotation of the spring spindle 30 in both directions. Attached to the rear plate 23 is a spring 93, Fig. 6, carrying a friction pad 94 adapted to bear against a disc on the turntable spindle 46. A bowed spring 96 is also secured to the plate 23, and carries a member 98 having transverse arm 101. 102. The arm 102 projects over the spring 93 and 101 projects over an extension 62 of an arm which supports the sound-box. A cam 104 extends from the part 98 and is adapted to be engaged by a pin 106 on the spring spindle 30. The spring 96 normally holds the arms 101, 102 out of engagement with the parts 93 and 62. The winding spindle 33 extends through holes in the members 96, 98, the upper hole being large enough to accommodate a pin 34 on the winding spindle. The winding key, Fig. 14, has a bayonet slot 36 adapted to engage with the pin 34 when the key is applied to the spindle. The head portion 109 of the key is larger than the hole in the member 98, so that when the key is pressed on to the spindle 33 to engage the bayonet slot with the pin 34, the spring 96 is flattened, and thus the pad 94 is forced against the braking disc on the spindle 46. At the same time the arm 101 bears against the member 62 and holds the sound-box off the record. On winding the spring, the pin 106, is moved away from the cam 104, and when the key is removed from the spindle 33, after winding, the friction pad 94 is free to spring away from the brake disc, the member 62 also being released to allow the sound-box to be applied to the record. At the end of the playing of the record, the pin 106 engages the cam 104, whereby the arms 101 102 are pressed against the parts 62. 93 respectively, to effect raising of the sound-box and application of the brake.

Abstract: 101,505. Caudron, R. Feb. 22, 1916. Steering.-A device for locking a foot-operated control member in any position, for use more particularly in aeroplanes, consists of a fixed ratchet member cooperating with two pawls acting in opposite directions and operated by pedals, one or other of the pawls being released when the control member is actuated. The device is shown applied to a rudder-bar o which has pivoted pedals c<1>, c<2> connected to spring-pressed pawls e<1>, e' engaging a fixed ratchet d having oppositelydisposed teeth d<1>, d<2>. On depressing one or other of the pedals, the corresponding pawl is released, and, as the bar moves, the other pawl slips over the teeth of the ratchet. A number of ratchet-wheels with offset teeth or pawls similarly offset may be used to reduce the effective pitch of the teeth.
