Title: Improvements relating to sealing structures for lead-in conductors in electric vacuum apparatus
IPC: H01B17/30
Filed: 1930-12-24
Abstract: 370,443. Vacuum switches; lead -in conductors. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rankin, W. K.; 267, Highland Avenue, Lansdowne, Pennsylvania, U.S.A.) Dec. 24, 1930, No. 38930. Convention date, Dec. 26, 1929. [Class 38 (v).] Lead-in conductors, such as 4, to the vacuum chamber 1 of electric vacuum apparatus, such as electric vacuum switches, are each resiliently supported in a glass insulating sleeve 32 the end of which are secured, one to the wall of the chamber and the other to the conductor 4 by means of flexible corrugated copper spinnings 33, 34, the conductor being biased by spring- urged bolts 16, on a flange 15 attached to it, so as to press a plate 23 on the end of the conductor within the chamber 1 against an insulating spacer 26. The bolts 16 carry springs 31 which bear against a cap 17 engaging an outer sleeve 19 of insulating material. The conductor 4 is hollow to permit the forced or convection circulation of cooling fluid which enters the outer sleeve 19 through a pipe 38 and leaves through the hollow conductor 4. In the hollow conductor 4 a tube 42 is secured and is expanded at its upper end 43 to form a tight connection with the conductor wall above apertures 41<1> therein which communicate with the outer annular space 41 formed by the sleeve 19. The cooling fluid passes from the pipe 38 through a ring conduit 30 into the space 41, and, moving upwards therein, passes into and down the annular space 44 in the conductor 4 from whence it passes up the pipe 42 out through the end of the conductor. A cupshaped shield 25 secured to the conductor 4 protects the spacer 26 from metallic deposits. The chamber 1 is exhausted through a tube 11 the end of which is closed by a cap 12 the edge of which is sealed by low melting point alloy 14. In an electric vacuum switch the conductor 4 is the fixed contact stud and the movable contact 3 is formed by an arm 5 which passes through a flexible diaphragm 6 to an actuating arm 8. The arm 5 is electrically connected to the chamber casing 1.

Title: Improved load responsive control for power systems
IPC: F02D29/00
Filed: 1961-10-31
Abstract: 925,310. Reciprocating pumps. A. PITT, and T. BUDZICH. Oct. 3 1 , 1961, No. 38975/61. Class 102(1). [Also in Groups XXIX and XXXI] FIGS 5 In a machine having a prime mover which drives a tool and means for feeding to the tool material to be worked upon thereby, the tool is driven through a transmission having a constant speed output and the feeding means is driven at a speed which is adjusted automatically to maintain a substantially constant load on the tool. The invention is described in connection with a threshing machine in which the rate of feed is determined by the speed at which the ground wheels of the machine are driven. In one embodiment, a variable-speed internal combustion engine drives the ground wheels through a fixed-ratio transmission and the tool or threshing mechanism through a variable-displacement pump and a fixed-displacement motor. The pump has a swashplate 57, Fig. 5, the inclination of which is adjusted to maintain a substantially constant rate of flow to the motor irrespective of speed variation of the engine by a piston 70 which is subject to the pressures upstream and at the throat of a Venturi 63a in the pump delivery line 63. The speed of the tool can be set by a manually adjustable spring 75 loading the piston 70 and the latter can be urged to the position corresponding to zero displacement to stop the tool by the admission of pressure fluid to a chamber 71a. The load on the tool is sensed by a tapping (not shown) from the line 63 which communicates with a chamber 92, Fig. 6, containing a spring-loaded piston 95 which, through a lever 112, acts on a control valve 103 so that on any departure from a pressure that is predetermined by the manual setting of a load-setting lever 114 connected with the lever 112 a servopiston 108 is operated to adjust the throttle valve 127 of the engine and thereby vary the speed of the ground wheels of the machine in a sense to restore the predetermined pressure in the conduit 63. When the lever 114 is set to the minimum load position the piston 108 is held by a loading spring 109 in its extreme rightward position and the throttle can be adjusted manually through linkage 130, 131 and 123. In a modification, a constantspeed prime mover driving the ground wheels through a variable-displacement pump as in Fig 5 and a hydraulic motor is employed, and the servopiston 108 acts upon the spring abutment 79 of this pump. In a further modification, also employing a constant-speed prime mover, the servopiston 108 acts on a pressure regulating valve which governs the action of servopistons controlling an infinitelyvariable transmission between the prime mover and the ground wheels.

In turning gear for slowly turning the rotor of a large steam or gas turbine while it cools after shut down, the hub of a clutch member 4 is connected to a shaft 1 by a torsionally resilient coupling wherein feather keys 2 in the shaft 1 engage slots 3 in the hub which are substantially wider circumferentially than the keys, a leaf spring 5 urging the hub angularly relative to the shaft to hold the keys 2 against one side of the slots 3 when the coupling is unloaded. The clutch is situated between the turning gear and the rotor and may be a magnetically engaged positive clutch as shown, or a free-wheel clutch. The turbine rotor is allowed to come to rest, and is then restarted by a turning motor having a flywheel in its drive train, the motor and flywheel being run up to speed, with the clutch engaged, in the time taken to take up the lost motion in the coupling.

Title: Ejector device
IPC: B64D25/20
Filed: 1959-11-19
Abstract: 873,345. Discharging from aircraft. DEVANTIER, K. E. Nov. 19, 1959 [Nov. 20, 1958], No. 39240/59. Class 9(2). Hydraulically operated means for ejecting a capsule containing a transmitter, such as that described in Specification 821,268, from an aircraft comprises a ram 5 aligned with the capsule 2 and exposed at one end to the pressure of the hydraulic fluid in a conduit 1, which also contains a piston 3a of greater weight than the ram. The ram has a head slidable in a chamber 6 formed by an enlargement of the conduit. On rapid deceleration produced by the aircraft colliding with an obstacle, the ram and piston tend to move forwards due to their inertia. Since they are of unequal mass the pressure set up in the hydraulic fluid by the piston thrusts the ram towards the capsule, which, due to its inertia also moves towards the ram, the air between in chamber 6 being compressed. A cutter 17 carried by the casing of the capsule punctures a plate 16 of frangible material, such as nylon, which closes a gas-filled chamber within the ram. The ram and capsule then move together towards the outlet of the conduit and detents 9b move radially inwards to prevent return of the ram due to the gas pressure. Meanwhile hydraulic fluid leaks along an annular passage 11 and thrusts detents 8b radially outwards, so that the capsule 2 can escape from the conduit. In a modification, instead of making the rod 3a very long, about 2 metres, and its path of travel at least 2À5 to 3 metres, to produce the momentum necessary for ejecting the capsule, the weight of the seats (and passengers) is operatively connected to the counterweight, Fig. 9. The counterweight piston 18 is connected to a flexible cable 20, which is attached to the seats in such a way that, in the event of a crash, the excessive deceleration causes the momentum of the seats to be transmitted to the piston and so operates the ram 5.

Title: A method and apparatus for continuous soaking of fibre material with washing liquid
Inventor: EKEGREN SVEN GUNNAR
IPC: D06B3/02
Filed: 1958-12-11
Abstract: <PICT:0867451/IV(c)/1> In a method for continuously soaking loose fibrous material e.g. raw wool, the fibrous material is constrained to move or fall into a chamber containing a quantity of washing liquid maintained in a continuous state of agitation by injection of a jet of the washing liquid below the liquid level in the chamber, the jet being directed towards a discharge opening provided at the bottom of an opposite wall of the chamber, whereby the fibrous material is discharged from the chamber.  Preferably the jet of washing liquid enters the chamber at right angles to its side wall. The method may be carried into effect using apparatus comprising a chamber containing washing liquid, an injection nozzle located in a side wall of the chamber and directed towards an elongated discharge opening at the bottom of the chamber in an opposite wall, the area of the discharge opening being variable.  As shown, a vessel 10 may have an intermediate wall 11 which can be raised or lowered.  Wall 11 and base 12 together form a discharge opening 13 of variable cross-section extending over the entire width of chamber 10.  An injection nozzle 14 opposite opening 13 directs washing liquid against wall 11 and flushes base 12 of fibres and solid impurities contained therein.  The fibres and their impurities discharged through opening 13 may enter a spout 15 which directs them to a further stage of a washing plant.  A splash guard 19 may be provided in chamber 10.  A safety discharge may function in the event of opening 13 becoming clogged.
