Title: Improved method and means for controlling the fire of guns on aircraft
IPC: F41A17/08
Filed: 1935-09-10
Abstract: 461,824. Controlling fire of guns on aircraft. NORTH, J. D. Sept. 10, 1935, No. 25119. [Classes 92 (i) and 92 (ii)] Relates to means for controlling the fire of an aircraft gun 1, Fig. 1, movable in elevation and azimuth, as for example on a ring mounting 4, so that firing is prevented when a part of the structure of the aircraft is in the line of fire, said means including as part of the firing circuit a screen member 11, Fig. 2, bearing on its surface a representation of the danger field 17 and a contact member 16 moving in elevation and training with the gun to be controlled, the firing being prevented when the contact member bears on the danger surface. According to the invention, the screen member is of cylindrical form and one of the gun movements, for example the training movement, is represented by a rotation of the contact member relatively to the screen, the other movement, for example the elevating movement, being represented by a linear movement of the contact member parallel to the axis of its rotation. In the form shown in Figs. 1 and 2, the contact 16 is carried by a cross-bar 14 which rotates in training with the ring 4, and is connected by links 12 with the elevating arm 2 to produce the required linear movement. In the form shown in Fig. 3, the contact member 27 is carried by the rotary ring 4 of the gun mounting, and has a linear movement in the slot 26 effected by a spring-controlled bell-crank lever 21 and a cable 18 connected with the elevating arm 2 supporting the gun. The contact member bears against a fixed cylindrical ring not shown, which bears the shaped danger field. The screen is generally formed of conducting material, the danger areas being represented by insulated insets, but the invention includes the use of raised or depressed danger areas when mechanical firing systems are used. Fig. 7 shows a pneumatic servomotor 58 for pulling the trigger 55 under the control of a rotary valve 61. The valve is shown in the firing position with a pressure port 60 and an exhaust port 64. To preclude firing under danger conditions, the screen 11 has a conducting surface corresponding to the danger area and the contact 16 is included in the circuit of a solenoid 53 which acts to open a release valve 65 and enable a spring 59 to move the trigger to inoperative position irrespective of the position of the firing valve 61.

Title: Training equipment for aviators
IPC: G09B9/18
Filed: 1942-10-21
Abstract: 600,128. Ground trainers for aircraft pilots. WEST, R. L. Oct. 21, 1942, No. 25154/45 Convention date, Feb. 11, 1942. Divided out of 573,953. [Class 4] A ground trainer for aircraft pilots comprises an arm simulating a propeller pitch control arm, a lever simulating a throttle lever, and a pair of gauges adapted to record the setting of the arm and lever, one of the gauges responding only to movement of the arm and the other gauge responding to movement of either the arm or the lever or to the combined movement of both. The invention is shown applied to a trainer provided with controls corresponding to those of a twin-engined aircraft, viz. starboard and port throttle levers 10, 11, pitch control arms 74, 75, tachometers 76, 77 and manifold pressure or boost gauges 78, 79. The starboard throttle lever 10 and pitch control arm 74 are interconnected by a cable 94 connected to a toothed sector 96 which meshes with a second sector 100, both sectors being mounted on a differential arm 98 pivoting on an axis midway between the axes of the toothed sectors. A link 102 connects the throttle lever 10 and the toothed sector 100. The tachometer 76 is operated by movement of the arm 74 through a link 82 and rheostat 84, and responds only to movement of that arm, the sector 96 remaining stationary when the lever 10 is moved, whereas the manifold gauge 78 responds to movement of either the lever 10 or arm 74, through a link 104 and rheostat 106. Additional rheostats 88, 110 may be operated by the instructor through a member 18 to simulate failure of the engine. The gauges may be operated pneumatically instead of electrically. Mixture setting levers 136, 137 may also be fitted, controlling lamps 146a ... d, 147a ... d visible to the instructor, the contacts for the levers corresponding to " off," " lean," " rich " and " full rich" settings.

Title: Refinement of benzene hexachloride
IPC: C07C17/38
Filed: 1952-10-09
Abstract: The gamma isomer content of benzene hexachloride is enhanced by holding an emulsion of benzene hexachloride, an emulsifying agent, water and a solvent as defined below, at a temperature at which the amount of benzene hydrochloride present is greater than the solubility of benzene hexachloride in the amount of solvent present, and separating the emulsion and solid phases after a finite time to obtain the gamma enriched fraction from the liquid phase.  The solvents used are those having a selective solubility for gamma benzene hexachloride and possessing, when containing in solution substantial quantities of benzene hexachloride, a range of immiscibility with water.  Typical solvents specified are benzene, toluene, chloroform, carbon tetrachloride, dichloroethylene, ethylidene chloride, tetrachloroethylene, ethylene dichloride, trichloroethylene, isobutyl chloride, methyl acetate, ethyl acetate, methyl propionate, n-butyl acetate, cyclohexane, cyclohexene, cyclohexanol, decahydronaphthalene, ethylbenzene, trimethylbenzenes, propylbenzenes, diethylbenzenes, xylenes, kerosene, n-butyl bromide, ethyl ether, dioxane and dioxane methanol.  Preferably, the weight ratio of benzene hexachloride to solvent is between 4.5 to 1 and 10 to 1, and the ratio of water to solvent between 5 to 1 and 10 to 1. Several types of emulsifying agents are specified.  In an example, (1) a solution of benzene hexachloride (containing 12 per cent of gamma isomer) in benzene is concentrated by distillation, emulsified in water using sodium 2-sulphonate-dioctyl succinate as emulsifying agent, cooled and allowed to stand 4 hours at 30 DEG  C., filtered, and the filtrate treated with sodium chloride solution to yield an organic phase containing 30 per cent gamma benzene hexachloride equal to 74 per cent of the gamma isomer originally present. Other similar examples are given, and modifications are referred to using other solvents.

IPC: F15B15/26
Filed: 1956-08-22
Abstract: 826,036. Locking rods. MERRYWEATHER & SONS Ltd. Oct. 24, 1957 [Aug. 22, 1956], No. 25652/56. Class 80 (3). [Also in Group XXIX] Means for locking a single-acting hydraulic jack against return movement of the jack piston in any position of the piston, comprises a one-way clutch device capable of preventing reverse rotation of a member having a screwthreaded connection with the piston. As described a pair of jacks for elevating fire ladders are supplied in parallel and each is provided with locking means. Each piston rod has a thread 3 engaging a nut 4 rotatably mounted in a collar 5 fast with the jack cylinder 1. A clutch plate 6 is fast with nut 4, and a clutch plate 7 has a screw connection with collar 5 and is brought into engagement with plate 6 when rotated reversely (i.e. the direction in which nut 4 rotates when the piston is retracted). Plate 7 is biased into light frictional engagement with plate 6 by a spring 9 acting on a piston rod 12 coupled to the plate 7. Application of hydraulic pressure to the jack to extend its piston results in a forward rotation of plate 6, so that plate 7 is rotated against the action of the spring to allow the clutch to slip. Any tendency of the jack to retract causes plate 7 to be screwed into locking engagement with the plate 6 and thus retain the jack piston in position. To retract the jack liquid is admitted through a line 13 to move the locking piston against the action of spring 9 to rotate the plate 7 forwardly out of engagement with plate 6. The locking piston uncovers a pilot line 15 through which pressure is supplied to open a non-return valve to release the liquid in the jack.
