Title: Improvements relating to the temperature control of exothermic reactions
IPC: B01J8/04
Filed: 1945-09-24
Abstract: In carrying out continuous exothermic reactions in which a fluid is contacted with a solid catalyst in a reaction zone the temperature of which must be kept within predetermined limits, a vaporisable coolant liquid, e.g. water, is injected into the reaction zone in sufficient quantity to maintain the reaction temperature within the desired range, e.g. 350-450 DEG  F., but not in excess of the amount which will be completely vaporised under the conditions prevailing therein, and in such a manner that the catalyst does not come in contact with unvaporized coolant liquid.  The fluid may comprise a polymer, e.g. di-isobutylene or an aromatic nitrohydrocarbon, e.g. a nitroxylene, preferably vaporised, and hydrogen.  The catalyst, which may be a hydrogenation catalyst, e.g. one or more metals of Groups VI and VIII of the Periodic Table or their oxides or sulphides, and preferably molybdenum sulphide, may be maintained in the reaction zone as a series of spaced beds, the coolant liquid being injected into the spaces therebetween.ALSO:In carrying out continuous exothermic reactions, e.g hydrogenation of a polymer such as diisobutylene or aromatic nitrohydrocarbons such as nitroxylene, in which a fluid is contacted with a solid catalyst in a reaction zone the temperature of which must be kept within predetermined limits, a vaporisable coolant liquid, e.g. water, is injected into the reaction zone in sufficient quantity to maintain the reaction temperature within the desired range, e.g. 350-450 DEG  F., but not in excess of the amount which will be completely vaporised under the conditions prevailing therein, and in such a manner that the catalyst does not come in contact with unvaporized coolant liquid.

Title: Improvements in or relating to liquid-dispensing devices
Inventor: HOMEWOOD GEORGE SIDNEY HENRY
IPC: B67D1/04
Filed: 1955-08-30
Abstract: 795,512. Dispensing aerated liquids. BRITISH SYPHON CO., Ltd. Nov. 23, 1956 [Aug. 30, 1955], No. 24870/55. Class 14 (1). [Also in Groups XVIII and XXIX] A pouring device which can be fitted to a container 5 to dispense liquid incorporates a locking means 15 which prevents a valve 9 controlling a pouring channel 3b from opening unless the device has been tilted to such an angle that the liquid in the container forms a seal over the channel 3b. A cap 1 is retained on the container 5 by a spring skirted cap 1 operated by a catch 7c. The valve 9 is located in a chamber 2 in the cap 1. The valve 9 with its sealing washer 10 is urged on to a shoulder at the bottom of the cap 1 by a spring 11 to seal the channel 3b. A short arm 13a on a cranked lever 13 extends through a slot in the cap 1 into a recess 9b in the valve 9. A ball 15 sits between a flat 13d at the end of the arm 13a and the wall of the chamber 2 so as to prevent the lever 13 from being depressed as long as the device is in the upright position. When the device has been tilted sufficiently the ball 15 moves into a curved recess 13c so that when the lever 13 is depressed the ball presses on a face 9c to open the valve 9 and allow the liquid to flow out through a spout 8. The spout 8 has a freely hinged cover 17 which protects it in the upright position, but opens freely when the device is tilted. Alternative methods for the attachment of the device, suitable for bottles with externally and internally threaded necks, are illustrated in Figs. 3 and 4 (not shown).

Transparent air distributing vanes 8 are secured by dowels or adhesive. The transparent portion of the hood may be attached to the non-transparent portion 1 as in Specification 536,484, the joint being covered by band 9. In a modification, the edges of the two half shells are secured by bolts and nuts to longitudinal metal strips which may extend over part of the non-transparent portion. The front of the top strip may carry a housing for an electric lamp and the strip may be apertured to admit light also to the interior of the hood. An air distributing vane may be formed integrally with the strip. Specification 502,245 and U.S.A. Specification 2,281,993 also are referred to.

Title: Improved apparatus for the destructive hydrogenation of solid fuels
IPC: C10G1/06
Filed: 1930-08-21
Abstract: <PICT:0363626/III/1> <PICT:0363626/III/2> A high-pressure vessel for the destructive hydrogenation of solid fuels contains a series of interlocking perforated trays a between which revolve transporting members b on an axle i.  Heat is supplied by electric means n, or by internal heaters.  Powdered fuel introduced at f passes down over the trays a in contact with hydrogen, which is introduced in a preheated state at g and passes up the annular space d between the vessel and the trays before meeting the fuel at the point h.  Vapour products and excess hydrogen leave by a pipe j, while ashes pass through a trap e to an ashpit below.

Filed: 1926-10-08
Abstract: 266,288. Dubilier Condenser Co. (1925), Ltd., (Assignees of Nyman, A,). Feb. 16, 1926, [Convention date]. Copying-telegraphs.-In order to modulate a carrier-wave in accordance with the varying light and shade effects, the output coil L2 of a thermionic oscillator 1 is coupled to a coil L3, which is connected in series with a biasing battery C and a photo-electric cell PC between the common filament circuit and the grid 2a of an amplifying valve 2. The grid filament circuit of the valve 2 is shunted by a high resistance Rg. The varying conductivity of the cell PC under the influence of a light-ray passing through a photographic film F sets up corresponding voltage fluctuations across the resistance Rg, which are applied to the grid of the valve 2 and so control the extent to which the electrical oscillators from the generator 1 are passed on through the amplifier 2 for subsequent transmission by any wellknown means. In a modified arrangement a single three-electrode valve functions as a combined oscillator and modulator.

Title: Improvements relating to the operation of nuclear reactors
IPC: G21C7/27
Filed: 1958-08-06
Abstract: 893,881. Nuclear reactors. COCKERILLOUGREE S.A. Aug. 6, 1958 [Aug. 6, 1957], No. 25213/58. Drawings to Specification. Class 39(4) A method of improving the utilization of the core of a nuclear reactor moderated with heavy water comprises using heavy water of commercial purity as moderator until the reactivity of the core has fallen to the minimum value acceptable for the functioning of the reactor, and then diluting the heavy water with ordinary water to allow an appreciable prolongation of the irradiation of the core. The dilution is preferably carried out continuously so that the reactivity is maintained at the minimum value. It is explained that the fuel irradiation time may be increased by about 20% in this way, and the saving thus produced is more than sufficient to cover the cost of re-concentrating the heavy water.

Title: Improvements in or relating to the exhaustion of closed containers such as are used for thermionic discharge devices
IPC: H01J7/18
Filed: 1925-10-10
Abstract: A pyrophoric base metal such as finely-divided iron, cobalt, or nickel is used for absorbing gas in a discharge tube or other container.  The metal may be obtained in a finely-divided state which is very reactive, by heating the formate, oxalate, acetate, or other organic compound of the metal.  Preferably a mixture is formed of such a compound with a similar organic acid compound of magnesium or similar metal, or with a compound of calcium such as lime.  Water is added to form a paste which is applied to the amount of the electrodes; or the lime absorbent may be applied to another part of the mount.  The bulb is exhausted by a pump and baked so as to drive off the metal.  After the bulb has been sealed off, the gettering action of the metal starts.
