    • An immersion heater for a water cylinder or water tank comprises a base section 2 having heating elements 7, a thermostat, and thermostat pocket (6, figure 3), a detachable middle section 3 connected to a power supply, thermostat sleeve and an electrical inspection chamber, and a removable cover section 24 having a thermostat reset button and securing fixings, where detaching the middle from the base disconnects the mains power supply to the immersion. The base may comprise an upper section having a rod thermostat and plug pins, and a lower section comprising heating elements and a rod thermostat pocket. The heating element may comprise single, dual, or multiple element rods. The connection means in the middle section may comprise hollow connection points receiving the plug pins. When the middle is detached from the base, the earth pin may be the last to disengage and closure means on the hollow connection points may close to prevent access to the power supply. The cover 24 may comprise a large cover section covering the supply connections and a small cover section 5 covering the thermostat and an over cut out reset button, the small cover section allowing safe inspection of the thermostat.

    • 746,843. Blasting and like fuzes. EVANS, V. L., MURPHY T., JONES, E., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 8, 1954 [May 18, 1953], No. 13860/53. Classes 9(1) and 9(2) A cord - like ignition device comprises a flexible incend i a r y waterproof envelope 4 confining a gas - permeable wick structure, the envelope being formed of a non - detonating deflagrating composition comprising a mixture of oxidizing and reducing agents bonded by a non - detonating combustible substance and having a high heatemissivity with low-gas evolution characteristies. The wick structure has at least one element comprising one or more filamentary portions. In the Figure the wick elements 1 consist of three cottons 2 spun together and impregnated with a black - powder nitrocellulose composition. The wick structure is spun and countered with two flat cottons 3 each consisting of six cottons of No. 30 count. The envelope 4 consists of a mixture of red lead, silicon and potassium chlorate bonded with a balata-rubber mixture. A paper yarn may be used for the wick structure and metal or textile filaments may be spun and countered around the outer surface of the device. In the given examples, the wick structure is impregnated with a composition comprising 30 parts nitro - cellulose solution and 20 parts sulphurless meal black powder. The envelope may consist of 26.2 parts plasticized nitrocellulose, 0.5 parts diethyl diphenyl urea, 23.0 parts red lead, 10.5 parts potassium nitrate, 22.2 parts potassium perchlbrate, 4.4 parts silicon, 8.3 parts calcium silicide and 4.9 parts flake charcoal. An alternative composition given is 10 parts rubber-balata composition, 47.0 parts red lead, 31.2 parts potassium perchlorate and 11.8 parts silicon, the rubber-balata composition being 25 parts mixed balatas and 7 parts rubber. All parts in the compositions are by weight. Specifications 652,542, and 728.240 are referred to.

    • 211,283. Lane, C., Hamilton, B. T., and Murphy, T. Dec. 12, 1922. Roulette; table games.-Apparatus for playing a table game of skill comprises a rotatable member 4 having a concave upper surface, a stationary ring 8 having a series of holes 9 to receive a ball projected centrifugally from the rotatable member. and a central hollow shaft 5 into which the ball is dropped at the commencement of the game, and from which it passes through an opening 6 on to the rotatable member which is integral with the shaft. The holes 9 in the ring 8 are each assigned a number, and the player rotates the member 4 by means of the shaft 5 with the object of causing the ball to enter a hole having a high scoring value. A second ring 12 is arranged beneath the ring 8 so as normally to prevent the balls falling completely through the holes 9. The ring 12 may be rotated by a handle 15 to a position in which a series of holes in it register with the holes 9 and allow the balls to drop. The apparatus is enclosed by a glass top 16. The balls may be released by coin-freed mechanism.
