IPC: F42B12/68
Filed: 1954-05-27
Abstract: 777,840. Signal rockets. WAECO, Ltd. May 27, 1955 [May 27, 1954], No. 15740/54. Class 9 (2). A signal rocket housed in a canister 25 containing an ejecting and igniting charge is provided with means to cause the rocket to spin about its longitudinal axis during flight. The rocket body 10 contains a propellent charge 11 held in place by a clay choke plug 12 and a clay plug 16 spaced from a perforated disc 19 beyond which is a flare candle 15 attached to a parachute 13. Within a passage through the plug 16 and between the plug and the disc 19 is a charge 18 for ejecting and igniting the flare. A stabilizer tail consists of a sheet metal collar 21 to which three anglesectioned fins 23 are attached by flanges 24. The collar, which has a fold 21a allowing adjustment of its diameter, is held in place on the rocket by tags 22 bent into a groove in the body 10. A spring-loaded firing pin 29 extending through a disc 27 and held by a toggle 30 is exposed when the canister lid 28 is removed. An ignition charge 34 is housed in a cylinder 31 also containing a delay fuze 33 and a percussion cap 32. To discharge the rocket, the cap 28 is removed and the toggle 30 broken so that the pin 29 strikes the cap 32 and thus ignites the fuze 33. Fuze 33 ignites the charge 34, which in turn ignites the charge 35. Charge 35 ejects the rocket and ignites the propellant 11. In a modification, Fig. 2, the tail unit is slidable on the rocket casing and comprises a collar 40 with sockets 42 in which fit rods 41, which may be skewed relatively to the rocket axis, so that the rods act as rifling during discharge and during flight the air pressure on the rods produces rotation of the rocket about its axis. Secured to the rocket, adjacent the choke, by a circlip 44 are three members 43 (one shown), which engage the collar 40 in flight. Each projection 43 contacts a rod 41 so that as the tail moves rearwardly the rods cause the rocket to spin.

May 29, 1931, Nos. 15798 and 23673. [Class 39 (iii).] Soil is raised to a high temperature for sterilizing &c. by being treated with alternating electric current while packed between electrodes mounted in a container. The container may consist of a cubical or rectangular box e, Fig. 2, and an outer casing h with an air space i between them. The box e has two opposite walls f of metal held in place by a floor and end walls g of wood or other insulating material. The box and casing are separated by a frame l and strips k of a phenol condensation product, wood, &c. A hollow or other lid m may be provided with a hole n for a thermometer &c., and the casing h with bushed holes through which electric cables are passed to sockets on the metal walls f. In the modification shown in Fig. 5, the lid m is hinged and provided with fastening hooks, and also with means to prevent the current from being turned on until the lid is closed, and the lid from being opened until the current is turned off. When the lid is open an L-shaped spring plate v on the container engages a shouldered recess u in a plate s on the spindle of a rotary snap switch, and so prevents clockwise motion of the switch. Anticlockwise motion is prevented by a cam engaging a fixed stop w. When the lid is closed it presses back the spring plate v and thus allows clockwise movement of the switch for turning on the current, a slot z in the plate s engaging a stud x on the lid to lock it. The whole outer surface of the container may be covered with sheet metal. In another modification the container is built of aerated concrete slabs one or more of the walls being hinged to form doors. Single phase or polyphase alternating current may be employed and several metal electrodes for use with polyphase currents may be removably mounted in grooves in the concrete slabs. Corresponding electrodes for adjacent containers may be connected together in parallel. The strength of the current may be varied by changing its voltage or frequency, or the area or spacing of the electrodes, or the resistance of the soil. To vary the conductivity of the soil it may be moistened with a solution of salt or fertilizer. A thermostat may be provided to control the temperature automatically by varying the current. The containers may be provided with handles, straps, wheels, rollers, runners, &c. to facilitate movement. The electrodes may be of galvanized iron, which may be corrugated. The container may be provided with legs. The first Provisional Specification describes an electrode secured to a wooden framework provided with legs.
