Title: Improvements in or relating to wireless control of distant apparatus
IPC: H03H9/46
Filed: 1923-08-22
Abstract: 222,285. Vickers, Ltd., and Ryan, C. P. Aug. 22, 1923. Controlling and actuating apparatus. -Tuned acoustic receivers of the type described in Specification 141,269 are utilized to actuate an inertia member such as a spring balance wheel of the kind described in Specification 11106/13 in a selective system of distant control. High-frequency signal impulses sent at intervals corresponding to the interval period of the wheel A are received by an aerial F, and the superposed note frequency of from 1,000 to 1,500 per second is repeated in a loud speaker H, which in turn actuates a local circuit K comprising a tuned resonator J and a telephone receiver L upon the diaphragm of which is mounted a chattering contact N. The vibration of this contact reduces the normal current flowing through an electromagnet D and thereby allows the wheel A to swing with increasing amplitude under the influence of the spring C. After a predetermined sequence of signal impulses an operative circuit is closed through contacts a<2>, e. In a modified arrangement the circuits K and M are coupled through a transformer.

Patent GB-793623-A (GB)
Title: Improvements relating to electrically driven pumps
IPC: F04D13/06
Filed: 1954-07-22
Abstract: 793,623. Centrifugal pumps; stuffing-box substitutes. GENERAL ELECTRIC CO. July 22, 1954 [July 24, 1953], No. 21438/54. Classes 110 (1) and 122 (5). A sump pump comprises an opening formed in the driving motor casing and communicating with the exterior, a pressure-sensitive means located in the opening and responsive to the liquid level, a switch operated by the levelresponsive means to energize the motor when the liquid reaches a predetermined level, the pump impeller having blades which exhaust the motor casing to create a holding force on the level-responsive means, and the holding force being relieved to stop the motor when the liquid level has fallen sufficiently to cause the blades to pump air. In the sump pump shown, a seal 30, of rubber or neoprene, prevents leakage of sump water into the motor casing 5 when the pump is stationary. When the water level in the sump has risen sufficiently, the hydrostatic pressure on the underside of a diaphragm 35 deflects the diaphragm to close a snap-action switch 36, thereby energizing the motor 7. The rim 33 of the seal 30 flies outwardly under centrifugal force and out of sealing contact with a stationary wall 23, and auxiliary blades 38 on the back of the pump impeller take over the function of preventing the sump water from reaching the motor casing 5. Initially, the blades 38 remove water from a cavity 14 and thereafter pump only the water leaking through a clearance between the blades 38 and an adjacent portion 40 of the pump casing. In recirculating the water, the blades 38 also withdraw air from the motor casing 5, causing a partial vacuum which exerts a holding force on the diaphragm 35 so that the switch 36 remains closed despite the fact that the water level in the sump is falling. When the water level has dropped to the point at which the impeller pumps air, the blades 38 cease to pump water and maintain a vacuum in the casing 5, and the switch 36 opens to stop the motor. The shaft bearings are lubricated by lubricant held in absorbent material 19, from which a wick 26 extends to an annular groove 25, leakage of lubricant being dealt with by slingers 21, 29. In a modification, the pump casing 1 is divided into a pumping chamber and a sealing chamber by an annular baffle in alignment with the impeller backplate 10, and an opening in the casing wall is provided above the level of the baffle. The blades 38 then pump against the pressure of the water in the sump instead of against the discharge pressure of the pump.

Title: Improvements in or relating to friction brakes
IPC: G05D13/00
Filed: 1931-07-28
Abstract: 380,894. Brakes; speed governors. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., and JOHNSON, E. N., 43, Belsize Park, Hampstead, London. July 28, 1931, No. 21553. [Class 103 (i).] A brake comprises two relatively movable surfaces between which a thick film of oil is maintained so that the braking action is due to the film of oil. The device is particularly applicable to centrifugal brake speed governors. That shown is a combined centrifugal and inertia governor applied to an electric motor. It comprises a pair of brake shoes 20, 21 pivoted at 18, 19 to a cylindrical member 17 secured to the shaft 16 of the motor and adapted to engage the interior cylindrical surface of a fixed drum 12. The shoes are connected by links 27, 28 to posts 25, 26 screwed into a flywheel 24 freely mounted upon the boss of the member 17. The posts 25, 26 pass through slots in the member 17. Posts 30, 31 also screwed into the flywheel and passing through slots in the member 17 are connected by springs 32, 33 to that member. A worm 40 on the member 17 serves to drive oil from a recessed portion 15 of the drum and through a channel 50 to the part of the drum engaged by the shoes 20, 21. The parts rotate in the direction of the arrow 52, Fig. 5, so that the movable ends or toes of the shoes are in advance of the pivoted ends and a thick film of oil is thus maintained between the shoes and the drum 12. In preparing the shoes these are at first formed with their engaging surface having a radius about sixteen thousandths of an inch less than that of the drum. The governor is then rotated with a grinding paste between the shoes and the drum until, with the toes of the shoes in contact with the drum, there is a clearance of about ten thousandths of an inch at the heels of the shoes. The range of thickness of the film of oil used is such that the frictional effect thereof diminishes rapidly with increase of thickness and is independent of the relative speed of the surfaces over a wide range of speed. Curves are given showing the behaviour of different oils at varying speeds and film thickness. In controlling steam or petrol engines, the drum 12 may be rotatably mounted and the torque applied thereto by the braking action be used by means of a coupling to control a throttle valve. Specifications 7023/89, [Class 37, Electricity, Measuring &c.], 20770/03, [Class 57, Governors &c.], 109,141, and 163,758, [both in Class 103 (i), Brakes &c.], are referred to.

Abstract: 517,327. Lathes ; chucks. BIRKIGT, M. July 20, 1938. No. 21560. Convention date, April 28.. [Class 83 (iii)] Multi - work spindle auto - meter turret lathe particularly for shell-turning has a workmagazine which is moved into a feeding position, so that a new workpiece may be fed into a chuck from which a finished piece has been ejected, and is then moved to an operative position to allow a tool carrying member to be moved up for a working- operation. The blanks 1, Fig. 10 are carried in the inclined magazine 6 which is hinged at 65, Fig. 5 and moved by cam and linkage mechanism into a position where the lowermost blank is in alignment with one of the six chucks which occupies 'the loading station and from which a finished blank has just been ejected. A plunger 67 carried by the magazine and operated by compressed air supplied through a cam-controlled cock, pushes the work piece into the chuck 5, Fig. 7, where it is gripped by toggle operated lever jaws 43 under the control of a spring 46. The chuck is previously opened up for the ejection of a finished workpiece by a member 48 engaging a spring sleeve 47 on the chuck occupying the loading &c. position; the member 48 being attached to an axial rod 50 operated by a spring returned air operated piston 51. The chuck ceases to rotate in this position through the operation of clutch-means 60 from a rod 62 the latter member engaging a fixed stop 57, Fig. 1 on the machine through which compressed air is also admitted to pass along the central hollow passage of the chuck to eject a finished workpiece. The work-drum is indexed through a cam and link operated ratchet finger and the tools are carried in a non-rotatable holder 3, Fig. 1, sliding along a central hollow cylindrical guide member 33 under the control of a cam drum 35 on the main camshaft 11. One of 'the tools 4<1>, Fig. 8, on the carrier 3 is adapted to cut a recess in the shell and is automatically given a radial feed movement, when a' part 79 contacts the end of the shell, through rotational movement of the toolholder by cam means 82. A supply of cutting and lubricating oil for the various parts of the machine is under the control of a cam which opens a valve on each forward stroke of the tool-carrier 3.
