Title: Improved process and apparatus for carrying out reactions with carbonaceous material
IPC: B01J8/18
Filed: 1943-08-12
Abstract: <PICT:0588089/III/1> Reactions involving carbonaceous material are effected by introducing hot finely divided solid into a reaction zone through a tubular member with a perforated discharge end, adding material adapted to produce a gaseous phase in the reaction zone wherein the solid is maintained as a fluidised bed, withdrawing spent solid to a chamber situated below said discharge end, and passing a stripping gas through the withdrawn solid and then into the reaction zone to return the stripped volatile products thereto. The solid may be either a reacting substance or a catalyst.  The reaction may be the catalytic cracking or conversion of hydrocarbons, or the oxidation, reduction, chlorination &c. of a hydrocarbon, or shale distillation, coal carbonisation &c.  Fig. 1 shows a hydrocarbon cracking plant wherein finely divided catalyst from standpipe 112 is fluidised by gas admitted at 316 and injected into reaction chamber 23 through flared conduit 16 with perforated end 18, so as to form a fluidised bed with surface at 22.  Hydrocarbon oil is injected into the catalyst through pipes 11, 111 supplying rings of nozzles 332, 336, Fig. 2.  The reaction products pass through a separator 26 from which catalyst is returned to the bed through legs 34, 35, and are led away by pipe 28.  Catalyst <PICT:0588089/III/2> passes from the bed down annular passage 48 into chamber 46 to which stripping gas is admitted by pipes 53 from circular headers 50.  The stripped catalyst passes into standpipe 64 from which it is suspended in regenerating gas and fed by conduit 76 to regenerator 78 in which it forms a fluidised bed, from which it flows over partition 86 into standpipe 112 for recirculation.  The exit gases pass through a waste heat boiler 118 and electric precipitator 128 from which the fines are returned to the regenerator after admixture of coarser material withdrawn from the system.  Extra heat may be supplied to the system by injecting oil into the regeneration zone at 192, or by burning oil in auxiliary burner 194 and using the hot combustion products as stripping or fluidising gas.  Draw-off lines 236, 242 are fitted whereby the catalyst, suspended in gas from pipe 226, may be transported to storage hoppers (not shown) when shutting down the plant.

Title: Improvements relating to pulse counting apparatus
IPC: G06F7/68
Filed: 1961-04-12
Abstract: 901,298. Frequency dividers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 12, 1961 [April 12, 1960], No. 13174/61. Class 106 (1). When the main counter is being reset at the completion of a predetermined count the incoming pulses are switched to an auxiliary counter, and when the auxiliary counter has reached a predetermined count the incoming pulses are again fed to the main counter. The frequency F1 to be divided is fed through gate 4 to the main counter 2 which has been set at a predetermined starting point by selectors 3. When the counter 2 is full it issues an output pulse F2. Simultaneously it signals 3 to reset the main counter. However, as this may take a time sufficient to lose some of the input pulses, the output pulse is arranged to operate gate 4 so that the input pulses are directed to auxiliary counter 5. When the auxiliary counter is full it restores gate 4. The presetting of selectors 3 takes account of the capacity of counter 5. Control of selectors 3 may be effected at a predetermined state of counter 5. In the modification of Fig. 3, counter 5 may be preset through selectors 6 at a certain stage of the count in the main counter 2. The inclusion of a ring counter 7 with one or more outputs between the main and auxiliary counters permits frequency division by a number including a fraction.
Patent GB-736404-A (GB)
Title: Process for the separation of oxygen-containing compounds from their mixtures with hydrocarbons
IPC: C07C29/74
Filed: 1952-05-26
Abstract: Acids and esters present in alcohol-hydrocarbon mixtures, particularly such mixtures obtained in the catalytic hydrogenation of carbon monoxide, are neutralized and saponified by treatment at elevated temperature and at a pressure at which substantially no evaporation of the mixture occurs with sodium hydroxide in quantity not higher than 20 per cent in excess of the theoretical quantity, removing any precipitated metal oxides by filtration, and separating the alkaline aqueous layer with the water-soluble alcohols from the upper hydrocarbon layer at the temperature used in the ester saponification.  The metal oxides which may be precipitated are derived from the catalyst used in the synthesis of the mixture and/or from the metal of the synthesis reactor.  It is desirable to carry out the saponification in the presence of one or more alcohols containing from 2 to 5 carbon atoms in the molecule.  Any olefins present in the washed hydrocarbon layer may be subjected to the Oxo synthesis.  The water-insoluble alcohols may be separated from the hydrocarbons in known manner, for example, by selective extraction or azeotropic distillation and any unsaturated alcohols or ketones which may be present are converted to saturated alcohols by hydrogenation. The alkaline aqueous layer which separates and is drawn off as the lower layer is cooled.  This results in two layers.  The upper layer containing higher alcohols is separated and the lower layer containing the combined alkaline washing and reaction waters may be distilled for the recovery of the water-soluble lower alcohols. The salts of fatty acids still present in the combined reaction and wash waters may be obtained in the dry state by evaporation.

Abstract: 354,259. Vehicle luggage-grids. HEWITT, N. E., 61, Norwood Road, Southall, Middlesex. May 2, 1930, No. 13621. [Class 103 (ii).] A vehicle luggage grid is attached to the vehicle in such a manner that it can be moved away from the back of the vehicle beyond its normal operative position and can swing in its own plane about either of its pivotal connections to the vehicle and can also be moved to a vertical inoperative position. The side members 11 of the grid 10 are each hinged to an arm 13 secured to the vehicle, each arm 13 supporting a bracket 16 comprising a projecting piece 20, two side members 15, and a bridge-piece 18 connecting the members 15 and passing beneath the arm 13 to take the weight of the grid. The projecting piece 20 on the bracket 16 is held between two horizontal eyes 19 on each side member 11, a pivot pin 21, having a thumb-plate 22, extending vertically through the three eyes. The portion of the pin 21 between the eyes 19 is formed with a flat 23 so that, on turning the pin, it can pass through a slot in the projecting piece and allow the grid to be swung away from the bracket 16 at this point. A spring at its lower end of each pin 21 draws the thumbplate 22 into a shallow groove on the upper surface of the eye 19, and a bearing plate 27 attached to each side member 11 bears on the under surface of the corresponding bracket 16, and relieve the weight on the pins 21 in the extended position of the grid. One or more legs may be pivoted to the grid to support it horizontally and to fold flat against the grid when the latter is turned to its vertical position. In a modification the two arms 13 may be of channel section to embrace the side members 11 so that the grid can slide along the arms. When completely detached the grid may be supported on folding legs each provided with a wheel or runner so that the grid may take the form of a truck. Specification 106,952, [Class 103 (ii), Rail and road vehicles, Details applicable &c. to], is referred to.

Abstract: 765,108. Gas manufacture. HUMPHREYS & GLASGOW, Ltd. March 30, 1955 [May 11, 1954], No. 13769/54. Class 55 (1). In a process for the manufacture of combustible gas by the carbonization of coal a part only of a supply of blue water gas from a water gas generator or generators is passed through coal whilst being carbonized, a smaller part of the blue water gas is enriched in carburetting apparatus which has been heated by the blow gases and the enriched water gas is added to the gases from the carbonizing plant. During the up-run gas making phase all the water gas from generator 11 is passed down through carburetter 12 and up through superheater 13 and into washer 14, the stack valve 27 and back-run valve 23 being closed, and butterfly valve 22 being open. During the first part of this phase oil is sprayed into the top of carburetter 12 and a deflector valve 20 directs the enriched water gas through secondary scrubber 15 to the gas main 19 through which the gases from retorts 18 pass. Subsequently oil spraying is stopped and valve 20 reset to pass blue water gas into the compensating holder 16 or direct to booster 17, feeding the base of retorts 18. During the following back-run phase, steam preheated in the superheater 13 and carburetter 12 passes downwardly through the. fuel bed in generator 11 and with valve 23 open and valve 22 closed, the blue water gas produced passes via connection 21 through washer 14 to the gas holder 16 or booster 17. In an alternative arrangement when oil spraying into carburetter 12 is stopped in the up-run phase, the blue water gas from generator 11 is passed directly through connection 24 to washer 14 by opening valve 25.

Abstract: 1501431 Making hollow charges; spinning; welding by pressure SOC NATIONALE DES POUDRES ET EXPLOSIFS and FRANCE ARMED FORCES MINISTER OF 3 April 1975 [17 April 1974] 13769/75 Headings B3A B3J and B3R [Also in Division F3] A method of making a conical bimetallic facing for hollow charges comprises explosively bonding two metal blanks of different types to form a bimetallic plate and shaping the plate into conical form by flow forming. One of the metals for the blanks produces a dense perforating jet when the hollow charge is fired while the other forms a core which either volatilizes or disintegrates. A sheet of copper or copper alloy which forms the perforating jet is explosively bonded to a sheet of zinc, lead, silver or aluminium which forms a volatilizable core or work-hardened steel which forms a disintegrating core. The bimetallic sheet, e.g. copper/aluminium having an initial thickness ratio of 1/5, is mounted in a driver 4 of a conventional spinning machine, and a conical facing is formed by advancing a rotating mandrel 2, which acts in co-operation with rollers 1, the copper layer being on the inside of the core. For bonding, an explosive charge comprised of 92À5% ammonium nitrate, 3À5% fuel oil and 4% wood flour, all by weight, is used together with a commercial detonator.
