Title: Improvements in or relating to locking devices for remote control and other force transmitting systems
IPC: B64C13/30
Filed: 1943-02-12
Abstract: 563,365. Locking levers. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. Feb. 12, 1943, No. 2372. [Class 80 (iii)] Relates to locking devices or to automatic hydraulic locking devices comprising an actuating member connected through a lost-motion device with an actuated member, a locking chamber containing liquid and which becomes reduced in volume as the actuated member is moved, and a valve arranged to be opened by the actuating member in taking up the lost motion to allow liquid to escape from the locking chamber. According to the invention, a movement-increasing mechanism is interposed between the actuating member and the lockreleasing member or valve whereby a small initial movement of the actuating member serves to release the locking action. The actuating lever is connected to a link 10 and the actuated member, e.g. an aircraft flap, aileron or other device, to a link 11. Between the links 10, 11 is interposed a locking device 12 which prevents movement of link 11 by any force other than that applied by link 10. The locking device comprises a cylinder 13 closed at both ends and containing a pair of pistons 17, 18 connected together by a pair of side members 19, 20, Fig. 2. Each piston has a packing cup 21 and a number of oblique passages 24 leading to axial bores 25, 26 containing valves 27, 28. Each valve is loaded by a spring 31 and has an axial bore 33 and transverse bore 34. At its middle part 'the cylinder has an upward extension 36 bored transversely at 37, Fig. 2, to receive a pair of end race members 38, 39 which support a hollow spindle 42 having a bifurcated arm 43, 44 fitting between the pistons, the spindle having a splined extension 45 to receive a main lever 46. The upper end of this lever is pivoted to link 11 and has a projection 48 on which is pivoted at 49 a bell-crank lever, the short arm 52 of which is connected to link 10 and the long arm 53 to a link 58 connected through an arm 62 to a spindle 63, Fig. 2, carrying a radial valve operating arm 65, a ball-end extremity 66 of which fits with slight clearance between the valves 27, 28. The ends of the cylinder have bleeder plugs 67, 68 and liquid is introduced through opening 36a, Fig. 2, and kept under pressure by a flexible rubber sac 69 in a protective cover 70. The bell-crank lever carries a pin 55 which passes through a larger hole in lever 46 to provide the lost motion. When link 10 is moved, the bell-crank turns relatively to lever 46 to move the head 66 and open the appropriate valve to permit the pistons to be moved when the lost motion is taken up and link 10 actuates link 11 directly. In a modification, the invention is applied to a locking device in which the pistons are connected directly to the actuating and actuated members as described in Specification 535,046.

Patent GB-724921-A (GB)
Title: Production of terephthalic acid
IPC: C07C51/27
Filed: 1953-01-28
Abstract: Terephthalic acid is obtained by oxidizing p-xylylene dichloride above its melting point with nitric acid of at least 20 per cent concentration without the application of pressure.  The acid concentration may be up to 65 per cent, preferably 45-60 per cent, and the oxidative power of the acid may be increased by recycling the gaseous products, e.g. NO, NO2, NOCl or N2O3.  The xylylene dichloride may be made into a paste with water, dilute nitric acid or the mother liquor of a previous batch.  If an acid of concentration below 40 per cent is used the oxidation is preferably carried out in two stages.  The crude product is purified by treatment with carbon tetrachloride and may, if desired, be esterified with methanol. Examples are given of the process, terephthalic monoaldehyde acid being obtained as a by-product.  Specifications 662,139 and 662,229 are referred to.
