Title: Explosive train arming device
IPC: F42C3/00
Filed: 1956-04-26
Abstract: 908,221. Mines and projectiles. PLANK, D. A. April 26, 1956 [Dec. 13, 1955], No. 12918/56. Classes 9 (1) and 9 (2). An explosive train arming device comprising a body member having a detonator charge and a booster or acceptor charge therein in spaced relation to one another, wherein a separating medium is normally located in the space between the charges having a shock-transmission characteristic sufficiently poor to prevent ignition of the booster charge by the explosion of the detonator charge, is provided with means for replacing the medium with a second medium having a better shock transmission characteristic whereby shock-waves caused by the explosion of the detonator charge will explode the booster charge. Fig. 3 shows a mine provided with a detonator 68 mounted in a cylindrical chamber which is normally full of air and is surrounded by an initiating booster charge 67. The cylindrical chamber communicates directly and through tubes 83 with orifices in the mine which are closed by soluble discs 77. The mine also includes a main charge 65 and a main booster charge 66. When the mine is immersed in water the discs 77 dissolve so that water replaces air between the detonator and the booster charge so that the mine is armed. If the mine breaks free from its moorings the water drains away from the cylindrical chamber surrounding the detonator, and the mine is disarmed. In an alternative initiating device, Fig. 2 (not shown), the cylindrical chamber surrounding the detonator can be filled with liquid from a reservoir by a pump which may be initiated by a clock device; the clock device may also be used to reverse the direction of the pump to disarm the device. Fig. 4 shows a projectile or rocket device wherein the detonator 103 is normally surrounded by a block 104 of soft steel or other material having poor shocktransmitting properties which prevents the booster charge 95 from being actuated by the detonator. The acceleration when the projectile is launched causes the block 104 to move rearwards and the liquid in chamber 96 passes through apertures in the block into the space surrounding the detonator so that after a time this space is filled with liquid and the block is retained in its rearward position by a snap-ring fitting into an annular groove 109. The time factor in arming the device prevents the train being armed by accidental dropping or by striking a nearby object soon after firing.

Title: Preparing oximes by reduction of nitro-cycloparaffins
Inventor: WILSON KENNETH BRUCE
Filed: 1954-05-05
Abstract: A process for the manufacture of oximes comprises reducing alkali metal or alkaline earth metal salts of nitro-cycloparaffins by means of an aqueous solution of sulphur and alkali.  The term "alkali" is defined as meaning the hydroxides, carbonates or bicarbonates of the alkali metals or oxides or hydroxides of alkaline earth metals and the reducing agent is prepared by dissolving sulphur in boiling aqueous alkali or by heating anhydrous alkali with sulphur and dissolving the product in water. The alkali metal or alkaline earth metal salt of the nitrocycloparaffin may be added to an aqueous mineral acid and the pH of the mixture maintained below 4 by further addition of acid.  In examples: cyclohexanone oxime is obtained by reducing nitrocyclohexane dissolved in aqueous sodium hydroxide solution with products obtained by boiling sulphur with aqueous sodium hydroxide (1) and (2); and by boiling with water the reaction mixture obtained by heating calcium oxide and sulphur (3), hydrochloric acid being added during the reduction.

Abstract: 233,163. Cook, E. T. May 30, 1924. Condensers. - In a variable condenser, the plates of opposite polarity are so arranged that they may be caused to move towards or away from each other in a direction substantially at right angles to their planes by a parallel motion device. In the form shown in Fig. 2, the fixed plates a are arranged to form a casing within which are arranged a pair of moving plates c pivotally mounted at opposite ends of a pair of links q pivoting on spindles r. The links q are connected by springs u, and the upwardly bent end of the lower plate c is provided with an insulating block t against which the plates c may be forced towards the plates a in opposition to the springs to vary the capacity, contact between the two sets of plates being prevented by sheets of mica d serving as dielectric. The screw f operates in a sleeve h which is in screwed engagement with the panel g and a fixed member m upon which is provided a scale co-operating with the operating knob l which is secured to the head of the screw f by a screw n. A terminal v is provided on the fixed plate a whilst connection to the plates c may be obtained through the spindles r. Alternatively, the plates a may be insulated from each other and arranged to form a dual condenser for tuning two circuits simultaneously. In a modification, a single fixed plate is arranged to co-operate with a single moving plate, the plates being made of V-shape to increase the area. In a further form, Fig. 6, the pivoted links are replaced by inclined planes x provided on the bottom of the casing and a single moving plate c is carried on spindles y, the ends of which engage in slots z formed in the side walls of the casing. The distance between the plates a, c is varied by the screw f which acts in opposition to springs u tending to draw the swindles y towards the upper ends of the slots z. The single screw f may be replaced by a compound screw, or, alternatively, a cam may be employed for displacing the moving plates.

Title: Improvements in or connected with acetylene generators
IPC: C10H15/02
Filed: 1930-04-30
Abstract: <PICT:0350166/IV/1> An acetylene generator in which a conveyer feeds the carbide from a hopper to the generating chamber, is provided with means for sealing the hopper from the conveyer and the generating chamber, these means being preferably associated with means for preventing the discharge of carbide from the conveyer to the generating chamber, in such a way that the hopper cannot be sealed until the discharge from the conveyer has been stopped. Also, means are provided whereby the hopper cannot be opened for charging until it has been sealed from the generating chamber. As shown, the carbide hopper 1 is provided with a flap valve 3 pivoted at 4 and actuated by a lever 14 and a cam or plate 13 secured to a rock shaft 12.  By means of a system of links and levers, the lever 14 also moves a cap 25 fitting over the screw closure 2 at the top of the hopper, the arrangement being such that the closure 2 is accessible only when the flap 3 is closed. A conveyer 7 feeds the carbide to the generating chamber, and for preventing discharge of carbide from the conveyer when the hopper is to be recharged, there is provided a flap 28 carried on a rock shaft 27 and actuated by a lever 29.  A rod 30 pivotally mounted on the lever 29 is adapted to engage a hole through the lever 14 and the shaft 12 when the flaps 28, 3 are open, with the result that the flap 3 cannot be closed until the lever 29 has first been operated to close the flap 28.  The conveyer 7 is preferably driven by a water-motor, the piston of which actuates a ratchet wheel on the shaft 34 of the sprocket wheel 8, and mechanism is described (Fig. 2, not shown) whereby the conveyer drive is cut out when the lever 29 is moved to close the flap 28.  In operation, the carbide is discharged from the conveyer down a shoot 38 on to a grid 41, and water is supplied from the water-motor by a pipe 42.  The sludge is carried round a baffle 43 to an outlet 45, as described in Specification 351,646.  When the hopper is to be recharged, the levers 29, 14 are operated in turn so as to close the flaps 28, 3 and lift the cap 25.  When the hopper has been charged, the lever 14 may be moved a short distance so as to open the flap 3 slightly, acetylene from the generator then displacing air from the interstices of the carbide.  The closure 2 is then replaced, and the movement of the lever 14 completed.  The flap 28 is opened last.  The flap 3 carries prongs 11 and rests, when open, on the conveyer 7, which is provided with ribs 10; the ribs 10 agitate the flap 3, and prevent the carbide from wedging in the discharge opening of the hopper.  A valve in the pipe supplying water to the motor may be automatically operated by rise and fall of a gas holder.
