    • 940,220. Timing mechanisms. G. Q. PARACHUTE CO. Ltd., and A. E. F. THOMAS. Oct. 20,1961 [July 20, 1960], No. 25276/60. Heading G3T. [Also in Division B7] A safety harness release timing mechanism for the ejection seat of an aircraft has two different delay periods. A rack 19 is urged to the left by a lever 30, 32 acted on by a spring 11 but is normally locked by a locking and interceptor pin assembly 39, 42. When the interceptor pin is removed on election of the seat, the rack 19 is freed to move leftwards at a rate determined by an escapement 26, 27 driven by gearing 21-25. The rate of rotation of the escape wheel is determined by the inertia of the pivoted anchor 27. The lever 30, 32 has an arm 34 connected by a link 35 to the arm 36 of a double-armed lever the other arm 38 of which normally latches a pair of hammers 3 loaded by springs 11, 16. The arm 34 rotates counter-clockwise as the rack 19 moves and at the end of the delay period releases the latch arm 38 from the hammers 3 which are actuated to strike pins 10 which fire cartridges 18 and cause a piston 6 to move to the left and effect release of the hammers from the ejected aircraft seat. If, before release of the rack 19 a bell crank lever 46 is rocked counter-clockwise e.g. by means responsive to aircraft speed, a second anchor 45 is brought into engagement with the escape wheel 26 to reduce its rate of rotation and so produce a longer delay period before harness release. The anchor 45 is weighted by a cylindrical element 47.

    • 578,049. Indicating devices. THOMAS, A. E. F. Jan. 6, 1944, No. 271. [Class 3 (ii)] [Also in Group X] A device for indicating the position of supplies &c. jettisoned from aircraft comprises a three- or four-legged pyramidal frame 1 which normally is folded up and carried in a tube 3 extending alongside the package &c. 4 thrown overboard. When the parachute first opens, the shock of retardation causes the frame 1 to slip out of the tube 3, and a spring 9 on a medial rod 8 by which the frame remains attached to the tube 3 through a cord 11 causes stretchers 5 to open out the legs 1 as shown. The extent of opening out is determined by a canvas triangle or quadrangle 10 attached at its corners to the legs 1, and this sheet acts as a kite which keeps the device away from the parachute during descent. When the ground is reached, two of the legs 1 will lie horizontally and one will stand upright. Each leg may carry an electric lamp 12 and a flag 13, the lamp automatically switching on when impact occurs, so that the location can be seen either by day or by night even if the supplies fall in scrub &c.

    • 14,742. Fowler, T. R. June 18. Acetylene.-Two generators for alternate use consist of an open outer chamber 1 and a closed inner chamber 2, the latter containing openwork carbide containers supported above the bottom by the part 4 of a pipe 9, 4, 10 connecting the two chambers. Water is supplied from a tank 24 by a pipe 26 to the chamber 1, whence it flows by the pipe 9, 4, 10 into the inner chamber 2. The gas produced passes by a pipe 13, fitted with a cock 12, to a coil 21 supported by the inner wall 20 of the tank of the gas-holder bell 23. After the water has risen within the inner chamber 2 above the pipe 9, 4, 10, the level rises in both chambers at the same rate, so that the progress of decomposition of the carbide is readily observed. The supply of water to the chamber 1 is controlled by a valve 27 connected by a chain 28 and lever 29 with a rod 30, on which is an adjustable nut 34 in the path of the top flange 33 of the bell 23. The nuts 34 are adjusted by hand so as to put only one generator in use at the same time. Each generator is fitted with a drain cock 5, which is connected by a pipe 15 and cock 14 with the top of the generator for drawing off the residue of gas with the water and lime. The cocks 5, 14, and 12 are connected by levers with the same handle 17, so that the cock 12 is always closed when the cocks 14 and 5 are opened. An arm 18 projecting from the handle 17 over the cover 6 of the generator prevents the removal of the latter before the cock 12 is closed. A pipe 43 connects the chambers 1 in order that the second generator may be started automatically if the exhaustion of the first should be unobserved. A safety escape pipe 35, which is normally sealed by a pipe 36 depending from the top of the bell 23, conducts away excess of gas when the bell is raised too high. Pipes 37, 39, and 41 conduct water of condensation from the pipes 35, 13, and 40 to a well 38.
