Abstract: 877,210. Automatic level control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 27, 1958 [March 9, 1957], No. 7862/57. Class 38 (4). [Also in Groups XVI, XXXVII and XXXVIII] In a web unwinding mechanism (see Group XVI) a switch 18 is provided in each compartment 11 to control the operation of motors driving the capstans 8a and 9a by opening when a maximum quantity of tape is present in one of these compartments, these motors then being supplied at reduced power through a resistance. Opening of one of these switches also causes, through operation of a relay, a further switch to close to supply the motor driving the corresponding spool to be supplied with reduced power. Further switches 19, provided in compartments 10 of the bins 6 and 7 are closed by lateral pressure of the tape when a compartment contains a predetermined maximum quantity, thus energizing the motor driving the appropriate spool to wind tape thereon from that compartment. Switches 22, provided adjacent the bottom of each compartment 11, are opened when the corresponding compartment is nearly empty to bring the motors driving the spools under the control of switches 19. The direction of tape feed past the transducer 2 may be reversed by operation of a switch, not shown, coupled to mechanism which controls the supply of suction to the suction rollers 4 and 5. Specification 877,209 is referred to.

Title: Improvements relating to gas generators
IPC: B01J7/02
Filed: 1952-03-31
Abstract: <PICT:0738816/IV (b)/1> A gas generator for the production of a gas by the reaction of a liquid and a solid comprises two separate closed vessels in which the solid and liquid respectively can be maintained under gas pressure, the said vessels being in communication through a porous element so that the passage of liquid into the vessel containing the solid is dependent on the relative gas pressures in the two vessels, the gas space in the vessel containing the liquid being connected to the outside atmosphere through a controlled leak comprising a second porous element.  The second porous element may comprise a U-tube, partly filled with liquid to cover the porous element and communicates with the said gas space at one end and with the outside atmosphere at the other end.  The generator is particularly suitable for the preparation of hydrogen sulphide or hydrogen.  In the Figure, the vessel 2 of generally tubular shape and preferably with an enlarged middle portion 2a contains the solid reactant 5 resting on a porous plate 6.  The liquid reactant is contained in vessel 1 and a second porous plate communicates between the gas space in this vessel and the outside atmosphere, e.g. by the U-tube 12 containing the porous plate 11 which may be covered with water, glycerine or other suitable liquid.  On opening control valve 8, the liquid reactant passes through the porous plate 6 to the solid reactant and the generated gas passes out through valve 8.  When the valve 8 is closed gas pressure forces liquid back into vessel 1 thus creating a pressure above the liquid 4.  The controlled leak prevents an excessive pressure developing in the vessel 1.  The pressures developed in the vessels 1 and 2 can be controlled by the porosities of the two porous elements 6 and 11 which may be sintered glass discs, or may be made of porcelain or of foamed polyvinyl chloride, rubber, polystyrene or methyl methacrylate, or of plastic-bonded inorganic materials such as kieselguhr.

Filed: 1936-03-20
Abstract: Batches of grass and/or green vegetable matter, and of the same with the addition of soil containing quantities of organic matter, are allowed to decompose in excess of water in separate tanks. Liquids strained off from the tanks are (with heating at various stages), mixed together and with sodium nitrate, p-dichlorbenzene, dilute sulphuric and phosphoric acids, methylated spirits, carbon tetrachloride, dichlorethylene, and ether.  The mixture is boiled with powdered carbon, e.g. coal soot, methylated spirits, and more of the liquids strained off from the tanks is added, and the mixture distilled to 80 to 90 DEG  C.  The distillate is mixed with acetone and fusel oil, which may be followed by other volatile organic liquids, e.g. benzine, carbon tetrachloride, ether, methylated spirits, and tar-oil naphtha, the mixture being added to the liquid strained off from a tank containing grass and/or green vegetable matter, soil containing quantities of organic matter, and coal tar. The liquid obtained is diluted in the same manner as the distillate referred to above, with the optional addition of water and petrol, and then distilled to 100 to 150 DEG  C. This distillate is in turn diluted in the same way to produce a motor fuel.

Title: Improvements in or relating to electric discharge devices
IPC: H01J25/60
Filed: 1944-05-03
Abstract: 587,775. Electron transit time apparatus. WESTERN ELECTRIC CO., Inc. May 3, 1944, No. 8397. Convention date, May 4, 1943.. [Class 39 (i)] An electric discharge device comprises a source 3 of a stream of electrons of initially uniform velocity which are subjected to the action of mutually perpendicular constant magnetic and electric fields, whereby the stream is constrained to move in a looped trajectory, and at a gap 4 near a loop of the trajectory cyclical velocity variations are impressed on the stream, whereby accelerated and decelerated particles describe different curves, particles following certain trajections being removed at a node following said loop, and at the next loop following the node, high-frequency energy is removed from the stream. In the arrangement shown the input and output means are gaps 4 and 5. between plates between which potential differences are maintained and electrons following trajectories with large loops such as 10 are removed by collision with the other boundary plate 2. When used as a generator the plates forming gaps are connected by a structure 14, 15, 16 which acts as a resonator and a feedback means to cause oscillation. The output connection 22 is coupled with this structure. A magnet 25 provides the magnetic field. The apparatus can be used as an amplifier by coupling input and output connections to the two gaps respectively. Cavity resonators can be used instead of the structure shown. The apparatus may also be modified to remove the slower electrons, instead of the faster. In this case the electron stream passes an input gap in plate 58 and the faster electrons pass between plates 54 and 62 and.pass to the output system 64 and 65. The slower electrons arc intercepted by plate 62. The apparatus may also be used in systems in which an oscillator and amplifier are coupled by an electron. stream.

Abstract: 1,183,699. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 17 Feb., 1969 [29 March, 1968], No. 8428/69. Heading G6C. A fuel element comprises a multiplicity of cylindrical fuel pins 1 disposed in a regular array to form a bundle, each of the fuel pins 1 being deformed at one end into a shape 2 having a rectangular transverse cross-section and being metallurgically bonded to at least one other of the fuel pins 1 along a face of the deformed shape 2. The fuel pins 1 are disposed in a plurality of adjacent rows and are metallurgically bonded, e.g. by brazing or electron beam welding, to each other along the smaller lateral sides of the deformed shapes 2, which sides are cut away to provide continuous passages 10 extending along the length of each row of fuel pins 1. The fuel pins 1 in the front row as shown in Fig. 7 are closed by the preferred method in which the larger lateral sides 3 of the shapes 2 are crimped toward each other and seam welded. In an alternative method, elongated caps 11 are inserted between the sides 3 and seam welded, as shown at the rear row of fuel pins 1 in Fig. 7. In practice, only one closure method is used in a single fuel element. An end fuel pin 13 of each row is not closed in the same manner as described above but is provided with a second deformed shape 14 oriented at right angles to the shape 2. The smaller end faces of the shapes 14 are joined together in the same manner as those of the shapes 2 and either of the above described methods is used to close the open ends of the shapes 14. One side face 4<SP>1</SP> of the shape 2 of each end fuel pin 13 is aperturod to provide fluid communication with the passages 10. The passage 15 formed through the shapes 14 acts as a collection manifold for gaseous fission products generated within individual fuel pins.

Title: Improved construction of fire extinguisher
IPC: A62C13/00
Filed: 1926-03-29
Abstract: 266,159. Denison, F. H. March 29, 1926. Portable pressure reservoirs.-In an extinguisher of the kind in which liquid is maintained in a container under permanent air pressure, the dip pipe D and outlet pasage C in the head B are arranged near the wall of the container A. Consequently when the extinguisher, in the inclined position shown, is charged with liquid through the passage C, a sufficiently large body of air is trapped in the container when the liquid submerges the end of the dip tube, over filling being prevented. Air pressure is then built up through the jet nozzle G, a fitting P having a spring-pressed ball-valve being interposed between the jet nozzle and the pump. The fitting P is fastened to the head B by straps U and springs. The extinguisher is sealed by a valve I on a screwed stem H co-operating with a valve seat E. The Provisional Specification describes also the provision in the dip tube of perforations by which air escapes until they are submerged by the liquid.

[Class 83 (iv).] Billet-piercing.-Tubes are formed by forcing a billet, when surrounded by a container, over a piercing mandrel by auxiliary hydraulic means, and then forcing a die into the billet by the main hydraulic ram so that the metal extrudes between the die and the mandrel. A billet C is placed on a die A carried on a hollow rod B on a hydraulically operated table K, and a container D is raised from a position in which it surrounds the rod B to surround the billet. The container, operated by an auxiliary hydraulic cylinder, and the table K, rod B, and die A are raised until the billet is pierced by a mandrel E, Fig. 2, and the container abuts against a guide ring F. This ring may otherwise be placed on the billet to form a guide for the mandrel in the piercing operation. The die is then forced into the billet by the main hydraulic ram and the tube extrudes through the hollow rod B, Fig. 3. The tube is removed by lowering the table K slightly, removing a distance-piece H, and again raising the table to sever the residue from the tube by an exposed cutter J.

Abstract: 884,524. Travelling-band filters. HIRS, G. March 11, 1960 [Sept. 23, 1959], No. 8626/60. Class 46. A portion of filter paper 84 is unwound from a spool 86 by an endless chain conveyer 58 and carried up a perforate inclined ramp 80 located between an inflow chamber 44 and an outflow chamber 45 only at the times when the pressure in the latter falls sufficiently (owing to clogging of the paper) to operate a bellows switch 118 which switches on a driving motor 98 for the conveyer. The paper is squeezed between the conveyer and a rubber-covered idler roller 116 at the discharge position. Undue vacuum in the outflow chamber 45 is at the same time prevented by partial return of filtrate thereto via a by-pass 126, a constant-head tank 125 and a solenoid-actuated valve 128 operated with motor 98. Filtrate pump outlet pipe 24 and an inlet pipe 28 form part of a machine tool coolant circuit. When the pressure in chamber 45 is restored, driving motor 98 is de-energized.
