Title: Improvements in and relating to oil switches
IPC: H01H33/04
Filed: 1932-01-22
Abstract: 384,116. High-tension switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Soc. GÚnÚrale de Constructions Electriques et MÚcaniques (Alsthom) ; 146, Avenue des Champs Elysees, Paris.) Jan. 22, 1932, No. 2068. Convention date, Jan. 22, 1931. [Class 38 (v).] In a liquid-break switch the movable contact 3 is mounted on the operating rod 8 immediately below a piston 2 which fits loosely within an insulating cylinder 1. When the contacts are in engagement the insulating liquid is arranged to extend to a height x, x immediately below the surface of the piston 2, the liquid level being maintained by a float or " birdfountain " apparatus communicating with the lower end of the switch cylinder through a non-return valve 10. Immediately the switch contacts are separated, the sudden rise in pressure produced by the vapour formed by the arc causes an acceleration of the movement of the contact 3, this acceleration continuing until the piston uncovers ports 7 formed in the side of the cylinder 1 and the vapour discharges. The movement of the contact is cushioned by the dashpot action of the air in the cylinder above the ports 7, the cushioning effect being assisted by a gland 12 around the rod which also prevents the escape of the arc gases around the rod and prevents their corrosive action on the portion of the rod which is surrounded by a spring contact assembly 11 bv which current is conducted to the movable contact. The loose fit of the piston 2 within the cylinder 1 permits the switch to be closed without appreciable retardation. The opening movement of the switch is initiated by the action of a spring which is under the control of latching mechanism. Specification 362,417 is referred to.

Title: Improvements relating to alternating current frequency converters
IPC: H02K47/18
Filed: 1953-01-26
Abstract: 728,473. Frequency converters. KRAUSS, K. Jan. 26, 1953 [Jan. 24, 1952], No. 2238/53. Class 35. The rotor of a frequency converter is driven through a continuously variable gear from a shaft rotating at constant or substantially constant speed. The principle of the invention is shown in Fig. 1 in which phase-splitting machine a which runs from single phase supply t and generates three-phase current of the same frequency f1, drives the rotor of a converter c through variable speed gearing b. The stator of the converter is fed with three-phase current at mains frequency, the output frequency f2 depending on the slip-speed of the rotor. If three-phase supply is available the phase converter a may be dispensed with. In a particular embodiment, Fig. 2, the motor and converter are in the same machine 1, the rotors b and c being concentric in the same three-phase energized stator a and coupled together through fixed gearing 2 and variable gearing 3. The outer rotor b is caused to rotate by the interaction of a squirrel cage or D.C. energized winding on its outer surfaces and the rotating field of the stator. The inner surface of the rotor b is polarized by direct current through slip-rings b1 to form a rotating field at synchronous or near-synchronous speed. The inner rotor c carries a polyphase winding supplying current through slip-rings c1, the frequency generated being dependent on the speed of this rotor. Rotor c is fixed to the same shaft as sun wheel K, the outer annular gear g is fixed to rotor b, and the planet wheel cage m is driven through variable-speed gearing o through gears i, q, p1, p2, at a speed producing the required frequency output. Specifications 524,598, 671,561 and 676,245, [all in Group XXIV], are referred to.

Filed: 1925-01-26
Abstract: 228,198. Persson, M. A. Jan. 26, 1924, [Convention date]. Void [Pusblished under Sect. 91 of the Act]. Rack-and-pinion actuated pumps; stroke, varying.-Relates to a device for locking and releasing mechanisms adapted to be actuated manually, mechanically or electrically, such as liquid vending apparatus and bolting arrangements. As applied to a coin-freed sale apparatus for liquids in which the pump piston is actuated through a rack from a pinion, the device comprises a receptacle 1 with a ring-shaped extension 2 constituting a coin guide at one side and a guide for a curved arm 7 at the other side, the arm 7 extending from an arm 6 fixed on a spindle 3 which is supported on the receptacle 1 and carries another fixed arm 5 engaging a recess 8 in the rack 10. Normally, the rack which is connected to the piston rod through a lost-motion device such as a pin and slot 27 cannot operate the rod owing to a lug 24 on the arm 6 coming against a pivoted two-armed lever 22, 23 gravity controlled to project into the coin guide. If, however, a coin or token has been inserted through the shoots 20, 19, the initial movement of the rack in operating the arm 5, and thereby the arm 6, causes the arm 7 to push the coin and rock the lever 22, 23 out of the path of the lug 24 so that the rack movement upwards can be continued to operate the pump piston, the coin passing down the shoot into the receptacle 1. At a position in the movement of the rack just before it moves out of engagement with the arm 5 a tooth 17 on the arm 6 engages a resilient device 18 on the ring guide 2 whereby the arms 5, 6 are held until on the return or descending stroke of the rack a projection 28 thereon engages the arm 5 and returns the parts to original position, the levers 22, 23 falling by gravity into position for arresting the arm 6. The rack may have graduation marks thereon and may carry an adjustable stop comprising a. sheet metal clamp 13 secured by a clamping lever 14 and carrying a stop member 15 adapted for fine adjustment by a screw 16.

Filed: 1962-01-24
Abstract: 922,504. Stuffing-box substitutes. JOHN ROYLE & SONS. Jan. 24, 1962, No. 2598/62. Class 122 (5). [Also in Group XXVIII] Pressure fluid contained in a cooling chamber 11 of a continuous vulcanizing apparatus, Fig. 3, is prevented from escaping between a wall 14 of the chamber and a sheathed cable 15 or its leading end 36, 37, as the cable is pulled through an opening in the wall 14, by means of a flexible sleeve 17 sealingly secured at its ends to the wall and to a member 25 adjacent their respective coaxial openings 20, 28, the inner surface of the sleeve being brought into adjustable sealing engagement with the cable or its leading edge by moving the member 25 relative to the wall 14 so as to expand or contract the bore of the sleeve. The member 25 is reciprocated by means of fluid motors 34 through a cross-head 31 and rods 26. The sleeve 17 is made from a length of relatively inextensible hose (see. Group XXVIII) and is clamped at one end on a bushing 19 by which it is initially twisted so that on movement of the member 25 towards and away from the wall 14 the bore of the sleeve is respectively expanded or contracted. The bushing may be rotated to give the desired twist by means of a motor connected to it. In a modification, the sleeve is untwisted and a length of wire, secured at its ends to the bushing 19 and to the member 25, is helically wound around or woven within the body of the sleeve or passed alternately inwardly and outwardly of the wall of the sleeve so that, on movement of the member 25 away from the wall 14, the wire is drawn tightly on to the sleeve and forces it into sealing contact with the cable. In Fig. 5 a metal ring 42 is disposed inside the sleeve 40 intermediate its ends to keep it distended. A split clamp 44 retains the sleeve on the ring 42. Aligned holes are provided in the ring, the sleeve and the clamp whereby cooling liquid under pressure has ready access to the interior of the sleeve so as to prevent water hammer from occurring within the length of the sleeve. In Fig. 6 the sleeve 17 is located outside the chamber 11 to the wall 49 of which is secured a housing 50 in which a member 54 attached to the sleeve through a bushing 57 can be reciprocated. A certain amount of pressure liquid seeps through the sleeve 17 and accumulates in the housing 50 under reduced pressure which may be maintained at a desired value below that in the chamber 11 by the provision of a bleeding valve. The difference in the pressures of the fluid inside and outside the sleeve helps in providing the seal between the cable and the sleeve. U.S.A. Specifications 2,561,820 and 2,883,702 are referred to.
