Title: Improvements in or relating to fog-projecting fire-extinguishers
IPC: A62C13/00
Filed: 1962-10-17
Abstract: 958,178. Fog-projecting fire-extinguishers. A. JACOBS. Oct. 17, 1962 [April 17, 1962], No. 39227/62. Heading A5A. [Also in Divisions B2 and F1] A fire-extinguisher which projects a cooling and smothering fog comprised essentially of a non-flammable liquid and gas comprises a tank 11 holding liquified compressed gas, e.g. CO 2 , from which gas may pass via a manual control valve 12 and a pulsating valve 14, which allows an intermittent gas flow, to a conduit and to the discharge gun 30 where some of the gas passes into the forwardly extending tube 36 which terminates in a multi-ported outlet 37 disposed centrally in a wider passage 52 into which a non-flammable liquid is fed from a tank 62 via a hose 48 and a conduit 51 in the gun. The remainder of the gas passes through a passage 54 in the gun to a tube 49 concentric with the liquid supply hose into the liquid tank 62 and into the gas-operated liquid flow control means comprising a valve body 94 into which gas enters at the upper end 96 thereof and act on a plunger piston 98 provided with sealing rings 105 and 106 and which is resiliently biased upwards and which, in its upper position, blocks the orifices 108 communicating with the interior of the tank. The gas urges the piston downwards allowing gas to pass into and thus pressurize the tank (via orifices 108) and at the same time causes the valve closure member 114 to leave its seating 120 and allow liquid to pass up the tube 124 from near the bottom of the tank into the tube 80 and thence to the hose 48 and discharge gun where it mixes with the gas issuing from the nozzle 37 to form the fog. In an alternative arrangement indicated by Fig. 3 (not shown), the liquid control valve is not present, the gas passing directly into the tank 62. The gas-supply nozzle of the discharge gun shown in Fig. 2 comprises an entry conduit 35 communicating with the exit conduit 38 which terminates in a plurality of discharge ports 39, 40 and 41, the latter two (of a total of 4 such ports) being disposed at angles of about 30 degrees to the port 39 and the axis of the exit conduit. Suitable liquids for use in the apparatus are water and water containing up to 50% of a flammable material, e.g. methyl alcohol or a material which produces hydrogen at fire temperatures, the presence of which is stated to improve the fire-extinguishing results of the apparatus. Specification 825,790 is referred to.

Title: Charge transfer devices
IPC: H01L21/339
Filed: 1973-08-21
Abstract: 1415944 Charge transfer devices WESTERN ELECTRIC CO Inc 21 Aug 1973 [23 Aug 1972] 39474/73 Heading H1K A charge transfer device of the bucket brigade type has sequential portions of each transfer region (channel) of different threshold voltages. Three or four voltages per channel may be used but two is preferred. There should be an abrupt change between the portions and the parameters of the device and operation should be chosen such that (in the two voltage case) the depletion region associated with a charge receiving region does not extend back beyond the other side of the adjacent (low threshold) channel portion. The device shown has left to right transfer and has the left hand portion of each channel given a higher threshold voltage by enhancing the substrate conductivity at that point. In Fig. 2 the same effect is achieved, with uniform channel doping, by locally increasing the insulation thickness. Other methods suggested are: the use of electrodes with contiguous segments of different work function; the use of insulation with portions of different dielectric constants; and (c) the use of electrodes formed in overlapping isolated sections biased at different levels.

Title: Improvements in or relating to nuclear fuel
Inventor: WILLIAMS NEVILLE RONALD
IPC: G21C3/64
Filed: 1969-08-06
Abstract: 1,256,033. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 21 July, 1970 [6 Aug., 1969], No. 39481/69. Heading G6C. A nuclear fuel body is formed by locating a plurality of coated fuel particles each overcoated with a matrix material/binder mix in a die to form a loosely compacted artefact, and compressing the artefact by means of a ram whilst subjecting the artefact to vibrations to produce a compacted artefact. Either the die or the ram may be vibrated, or the artefact may alternatively be vibrated by means of a probe which does not directly vibrate the die or the ram. Such a probe is useful in the manufacture of hollow cylindrical fuel pallets. The vibration serves to lower the pressure necessary to effect compaction and yet still attain the desired matrix density, and hence there is less likelihood of the fuel particle coatings cracking. An increased concentration of coated particles in the matrix which requires an increase in the compaction pressure can be accommodated without undue cracking of the particle coatings using this method. When the matrix material is graphite powder and the binder is a phenol-formaldehyde resin, the compacted artefact is heated first to between 70‹ and 200‹ C. to cure the binder, then to 850‹ C. in an inert atmosphere to carbonize the binder, and finally to 1850‹ C. in vacuum to outgas the artefact. The matrix material need not be graphite, other suitable materials being any suitable ceramic, e.g. Al 2 O 3 , or a metal powder, e.g. Ni or stainless steel.

Abstract: 872,712. Feeding mechanism for stamping presses. GENERAL MOTORS CORPORATION. Dec. 2, 1959 [Dec. 24, 1958], No. 40944/59. Class 83 (4). [Also in Group XXV] An assembly for blocking downward movement of an arm 14 which removes or feeds workpieces 12 to or from a stamping press 2, comprises a hooked member 42 pivoted offcentre such that when the member hangs freely the hook 44 extends into the path of travel of the arm 14, and a plunger 50 which can engage the member 42 to urge the hook out of the path of travel of the arm. The hooked member 42 is pivoted at 40 to, and moves between, plates 32 and 34 fixed to the press, the plates also carrying a tubular housing 46 in which is disposed the plunger 50, a spring 48 and an operating plunger 58, the latter being adapted,when it is moved up the housing 46 by means of a handle 66, to load the spring 48 and thus the plunger 50; a detent 62 on the plunger 58 moves up a slot 64 in the housing 46 and the plunger 58 is retained in its upper position by rotating the handle 66 so as to engage the detent 62 in a shorter slotted portion 76. In the latter position of the plunger 58 the hook 44 is normally in its retracted position and the arm 14, which is hydraulically operated, is free to move for normal working. In operation of the blocking assembly the plunger 58 is moved to its lower position, as shown in Fig. 5, so that when the arm 14 is raised it is automatically engaged by the hook 44. When the arm 14 is to be released the plunger 58 is returned to its upper position, thus spring-urging the hook 44 to its retracted position; the hook, however, remains in its engaging position by virtue of its frictional engagement with the arm until the latter is again raised. The arm 14 is pivotally supported on guide members 16 slidably mounted on guides 18 and, upon movement of the arm, rollers 24 thereon engage cam surfaces 28 to cause the arm to swing on its pivot. The lower end of the arm is provided with an hydraulically -operated mechanical gripper 22. The ram of the press 2 is movable by means of a pulley and crank, the pulley being connected by a chain drive to a cam-type limit-switch for actuating an hydraulic device.
