Title: Fluid-pressure relay devices particularly for brake mechanisms of aircraft and the like
IPC: B64C25/48
Filed: 1947-07-11
Abstract: 638,373. Valves controlled by auxiliary valves. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. July 11, 1947, No. 18411. [Class 135] [Also in Groups XXXIII and XXXIV] A fluid-pressure relay device for the control of two fluid-pressure operated mechanisms, e.g. brakes on aircraft, comprises a casing with two compartments 7a, each having an inlet 4, a valve control member 16 with an exhaust passage 18, and an actuating member 23 having a lost-motion connection with the member 16. Diaphragms 10, 13 and 19 divide each compartment into an operating section 7, an exhaust section 11 and a control section 14, and the inlet and exhaust passages are controlled by interconnected inlet and exhaust valves 5, 8 respectively. On supplying pressure-fluid to the control sections through a port 15 and under the control of a manually-actuated device, the members 16 rise to close the exhaust valves and open the inlet valves, thus permitting pressurefluid from a common inlet 3 to pass to the mechanisms through ports 9. The inlet valves close when the pressures in the sections 14 and 7 are equal. The members 23 abut a beam 36 having a movable fulcrum 37, which may be controlled by the rudder bar in an aircraft, whereby differential pressures may be applied to the mechanisms. In a modification, two control devices control the relay through a shuttle valve, and in another arrangement, an extra actuating member is mounted in each compartment. The diaphragms may be replaced by flexible stockings, bellows or pistontype sealing rings.

Title: Improvements in or relating to production of uranium and plutonium
Inventor: MYERS RUPERT HORACE
IPC: C22B60/02
Filed: 1950-07-27
Abstract: Uranium or plutonium is obtained by heating a mixture of the oxide and a particulate alkaline into metal (including Mg) to produce a reaction product in which particles or beads of the U. or Pu. metal are dispersed in a mass of alkaline earth metal oxide, and recovering the metal beads by leaching the product with water and/or aqueous acid to remove alkaline earth metal oxide and any excess alkaline earth metal from the said beads, the leaching being effected under conditions such that the resulting liquor in contact with the beads of U. or Pu. remains alkaline. Preferably the oxide is in powder form, the reaction occurs in a calcium oxide lined vessel, Ca or Mg used in excess, an inert atmosphere e.g. argon is used, the reaction product is heated rapidly to 1200 DEG C. and held there for 30 minutes, allowed to cool (in argon) then crushed avoiding disintegration of the U. or Pu. beads, and leached by tumbling in 20 per cent acetic acid.  The U. or Pu. beads may be washed and dried or coated with mineral oil or wax.  Uncoated beads may be compacted into e.g. rods by cold pressing at up to 30 tons p.s.i. followed by sintering in vacuo or in an inert atmosphere, or by hot pressing at temperaures up to 1000 DEG C. in inert atmosphere at 1/2 to 1 ton p.s.i.  Coated beads require any hot compacting at 1000 DEG C. under 1/2 to 1 ton p.s.i.

Abstract: 221,196. Renault, L. Aug. 28, 1923, [Convention date]. Actuated by running axle.-A servo-brake device operated by the rotation of a wheel axle is designed so as to enable the brakes to be applied when the vehicle is travelling either backwards or forwards, or is at rest; in modifications, when the vehicle is travelling forwards, or is at rest Fig. 1 shows a servo-brake operating mechanism comprising a band 3 connected at its ends respectively to an operating pedal and to the brakes and surrounding a pulley 2 loosely mounted on an axle 1. When the band 3 is tightened round the pulley, the screw 6 moves it to the right or left, according as the vehicle is moving backwards or forwards, and engages the pulley with either the cone 10, which is rigid with the axle 1, or with the cone 16, which is driven from the shaft 1 by means of an intermediate gear wheel 13. In either event the pulley 2 is rotated in the same direction and the brakes are applied. In a modification the cone 16 and its accessories are omitted so that the servo-brake device operates only when the vehicle is travelling forwards, and this may be further modified by replacing the friction clutch 10, 2 by a dog-clutch. The shaft 1 is driven by the gear 19 through dogs 17, 18, the play between which facilitates the disengagement of the clutches. Fig. 6 shows a. device in which worm gearing 29, 32 rotates a shaft 33, on which the servo-motor pulley or drum is mounted. When the drive is such that the worm 29 moves to the right, the clutch 26, 27 engages; when the vehicle travels backwards, the clutch 26, 27 disengages, and the plate 34 abuts against the plate 36, which, with the spring-pressed part 35, forms a friction clutch; this slips as soon as the brake control is operated, and the brakes are applied without using the servo-motor.

Abstract: 613,709. Impedance networks. GENERAL ELECTRIC CO., Ltd., and COLLETT, E. W. June 26, 1946, No. 19128. [Class 40 (viii)] An equalizer consists of a four-terminal network having an iterative impedance Z0 which is substantially purely resistive and comprises one or more series impedance elements of value Z1 and one or more shunt impedance elements of value Z2 such that Z1 Z2=Z0<2>, wherein means are provided whereby the value of Z1 can be changed to a number of values K1 Z1, K2 Z1, &c. and whereby the value of Z2 can be changed to a number of values 1/K1 Z2, 1/K2 Z2, &c., where K1, K2, &c. are different, and preferably consecutive, integers or the square roots of such integers. This inverse variation of Z1 and Z2 alters the propagation constant of the network by integral multiples and permits the equalizer to be adjusted to smooth out the transmission on a route consisting of any desired number of standard cable lengths. In the first embodiment, Z1 consists of an inductance L1, condenser C1 and resistance R1 coupled by a transformer T1 having tapped windings over a pair of impedances Z0. The impedance Z2 comprises a similar inductance L2, condenser C2, resistance R2 and transformer T2. Variation may be obtained by tapping the resistances instead of using transformers. The second construction shown is in effect a lattice network as, though there is only one impedance Z and one Z2 they are coupled in a network by tapped transformers T1 and T2, each with two primary windings and together forming the lattice.
