Title: Improvements in cathode ray tube apparatus
IPC: H03K4/10
Filed: 1938-09-12
Abstract: 519,168. Cathode-ray tubes ; photoelectric cells. TIHANYI. K. Sept. 12, 1938, No. 26582. Convention date, Sept. 13, 1937. [Class 39 (i)] [Also in Group XXXVI] The electrostatic or electromagnetic deflection of a cathode-ray across a television or oscillograph screen is controlled by relay or switch cells inside the cathode-ray tube and acted on directly by the ray. These cells may comprise associated fluorescent and photoelectric materials so that the ray causes fluorescence to control the photoelectric effect (Fig. 4, not shown), or two phosphorescent layers with or without an interposed light filter may be used so that the under layer gives an after-glow. In modifications, the cells.are gas-filled photo-electric cells in a common vessel or in separate vessels or are of the selenium or thallofide type and give a varying resistance. As shown in Fig. 1, the cathode-ray K is deflected by a synchronizing impulse applied to a small plate 6 so that the ray impinges on a cell 3 which allows the gradual charging of the deflecting plates 1, 4 from a constant voltage source through a resistance R. The ray is consequently gradually traversed to the left until it strikes a cell 2 which interconnects the plates 1, 4 to cause rapid return of the ray. In modifications, the charging of the plates 1, 4 is controlled by a third cell acted on by an auxiliary cathode-ray (Fig. 3, not shown) or the plates 1, 4 are replaced by coils the deflecting currents through which are similarly controlled (Fig. 10, not shown). The resistance R may be temperature constant and composed of two or more substances such as benzene, alcohol, picric acid and phenol. The liquid 25, Fig. 7, is enclosed in double-walled quartz tube 23, 24 and cooling liquid is passed through the inner tube 24 during the heating of the cathoderay tube in the evacuation process. The resistance R is preferably mounted within the cathode-ray tube. The source E of plate charging current may be stabilized in voltage. Specification 315,362, [Class 39 (i)], is referred to.

Title: Nuclear reactor including a shutdown device
IPC: G21C9/033
Filed: 1973-06-04
Abstract: 1404255 Nuclear reactors GROUPEMENT POUR LES ACTIVITIES ATOMIQUES ET AVANCEES 4 June 1973 [2 June 1972] 26594/73 Heading G6C A nuclear reactor including a safety device employing a neutron-absorbing liquid such as Li-6, comprises a reservoir 11 defining an upper compartment 15 above the core and a lower compartment 15<SP>1</SP> in the core, the upper compartment 15 normally containing the absorber and gas under pressure P1 while the lower compartment contains gas at a higher pressure P2, and a piston 23 movable in a casing 8, the piston having an orifice 23<SP>1</SP> opening into a tube 24 whose lower end engages, in the lower position of the piston, a member 17 carried at the upper end of a tube 16 and extending from the lower compartment 15<SP>1</SP> through the upper compartment 15. Upon opening of an electromagnetic valve 28 to introduce gas above the piston 23, the latter moves downwards in the casing 8 since a ballvalve 31 at the lower end of tube 24 is closed. As the lower end of tube 24 enters the open, upper end of a easing 10 housing reservoir 11, a spindle 32 projecting from the member 17 opens ball-valve 31 so that gas passes through the interior of tube 24 and hence into tube 16 to raise compartment 15<SP>1</SP> to the pressure P2 so forcing the liquid absorber from that compartment, via a syphon 20 to the upper compartment 15 and creating pressure P1 in the latter. The safety device is now ready for operation. When it is required to release the stored absorber into the core, a quick-acting valve 27 is opened to release the pressure in the casing 8. Residual pressure below a ball-valve 33 causes the latter to close and the piston 23 rises under the action of spring 30. As soon as the lower end of tube 24 brakes away from a seal 21, the pressure P2 in compartment 15<SP>1</SP> is released and the absorber is forced into that compartment so reducing reactivity. Residual pressure in tube 16 urges the member 17 upwards to seal the top of the tube 16 against ingress of sodium coolant. Gas escaping from compartment 15<SP>1</SP> passes up through the space between tube 24 and a surrounding tube 9 to debouch from the same into a layer of argon or helium cover gas above the sodium. Slower reactivity adjustments can be effected via the valve 28.

Title: Improvements in control devices for free piston internal combustion engines
Inventor: MORAIN WILLARD ARAM
IPC: F02B71/00
Filed: 1951-11-14
Abstract: 705,962. Fluid-pressure servomotor-control systems. BALDWIN-LIMA-HAMILTON CORPORATION. Nov. 14, 1951, No. 26649/51. Class 135. [Also in Group XXVII] The stroke of a free piston internal combustion engine 10, Fig. 1, acting as a gas generator supplying a turbine, is controlled by admitting air to or venting it from the bounce chambers 11 under the control of a device 20 in accordance with the mean pressure in the chambers, and the exhaust pressure of the engine. The device 20, Fig. 2, comprises a body having connections 22, 24, to the exhaust line 10a and a source of compressed air, e.g. bottle 26, respectively and two connections 28, 30 to a line 12 interconnecting the bounce chambers the connection 28 being so constructed as to provide in a chamber 74 beneath a diaphragm 42 the mean pressure in the line. The exhaust pressure acts on a piston 34 connected via a spring 36 to a valve seat 38 carried by the diaphragm 42, a bore 48 in the seat being controlled by a closure member 52 the stem 54 of which extends to contact a closure member 58 controlling the outlet of a cylinder 88. Slidable in this cylinder is a piston 86 carrying a closure member 80 in a chamber 82 controlling communication between connections 24 and 30. Inlet pressure from connection 24 acts through a bore 94 on the underside of the piston and through a restriction 92 on the upper side, and a spring 96 urges the member 80 to its seat. When the stroke is correct, members 52, 58 and 80 are seated. If the exhaust pressure increases, piston 34 unseats member 58 causing piston 86 to unseat member 80 to supply air to the chambers to reduce the stroke. A pressure decrease in the line 12 has a similar effect by permitting the spring 36 to unseat member 58. A decrease of exhaust pressure causes upward movement of the diaphragm, the member 52 engaging stops 64 whereby further movement of the diaphragm opens bore 48 to vent air from the chambers via an opening 50a. A similar effect is caused by an increase of pressure in the line 12, acting on the diaphragm to compress spring 36. In a modification, the pressure in the reverse bounce chambers 17 is applied via a line 100, Fig. 3, to a piston 34a, integral with piston 34. Specification 663,165 is referred to.

Title: Improvements in or relating to the electrolytic deposition of metals from slurries (or pulps)
Inventor: WILLCOCKS REGINALD GERALD WALL
IPC: C25C7/00
Filed: 1955-09-20
Abstract: 801,397. Electrolysis. RHOANGLO MINE SERVICES, Ltd. Sept. 19, 1956 [Sept. 20, 1955], No. 26875/55. Class 41. A process for depositing a metal, e.g. copper, from a slurry comprises electrolysing the slurry between two electrodes in the slurry and imparting a rotary motion to all or part of the slurry so that centrifugal force on the slurry is directed away from at least one of the electrodes whereby deposition on that electrode takes place in a zone of clarified liquid, e.g. the slurry may be delivered by a pump tangentially into the annular space separating two concentric electrodes. The centrifugal force produces an acceleration at least equal to that due to gravity. In one embodiment, Fig. 1, a rotor 1 comprising a solid or hollow non-conducting prism of polygonal cross-section is mounted in a vessel 11. Each face of the prism carries a conducting sheet 4 supplied with current by studs 6 and conductors 7 which are connected to a source 10 through a slip-ring 8 on a shaft 9. The vessel 11 is of lead or lead alloy and forms the other electrode, or electrodes may be disposed around the inner surface of the vessel. In a modification, Fig. 4, the rotor comprises a number of concentric electrodes 12, 13 of alternate polarity mounted on a non-conducting body 14, current being supplied via the rotor shaft. Scoops may bridge outer pairs of electrodes at the bottom of the rotor to encourage flow of slurry up and down between the electrodes. In another modification, Fig. 6, a central electrode 17 may be stationary or rotatory and is surrounded by a concentric, non-conducting, perforated or slotted cylindrical rotor 18. An electrode 20 surrounds the rotor 18. In a modification of the Fig. 6 embodiment, a hollow rotor carrying electrodes on its inner surface surrounds a fixed or rotatable central electrode, and in this case the rotor is also the vessel for the slurry. The function of the rotor is to keep solid materials in the slurry away from one electrode, e.g. the cathode, where they would contaminate the deposited metal, and move them to the anode where metal-containing solids are subjected to a reaction which dissolves the metal in the solid for subsequent deposition on the cathode. In one example, the slurry comprises copper in sulphuric acid which bears insoluble copperbearing solids, and in another example the slurry is a calcine, containing copper and cobalt, in sulphuric acid.

Abstract: Crystalline mixed alkali metal tripolyphosphates having alkali metals M1, M2 and phosphorus present in the molar ratio 3-3.2M1 : 2-1.8M2 : 3P are obtained by reacting a solution of an alkali metal orthophosphate with a compound (other than a phosphate) of another alkali metal, the proportions being such as to provide the above molar ratios, evaporating if desired and heating the mixture at 500-1200 DEG F.  If desired phosphoric acid may also be present in the reactants to obtain the desired ratios.  Specified alkali metals are sodium, potassium and lithium, orthophosphates referred to are the mono-alkali metal salts, and other compounds mentioned are sodium carbonate, hydroxide, formate, acetate and oxalate.  In the preferred procedure, an aqueous solution of impure phosphoric acid (obtained, e.g. from phosphate rock with sulphuric acid and containing iron and aluminium in solution) is reacted with potassium chloride (e.g. sylvite) or sulphate, the mixture fired at 1400-2000 DEG  F., quenched in water and autoclaved at 165-225 DEG  C. to produce mono-potassium orthophosphate from which impurities may be separated by filtration or centrifuging.  Three mols. sodium carbonate are then added per mol. of the orthophosphate and the mixture evaporated to 75 per cent solids.  The resulting paste which has the components present in amounts corresponding to the formula K3Na2P3O10 ma be heated in a rotary kiln at 1000 DEG  F.  Alternatively the aqueous solution may be spraydried and then heated at 1000 DEG  F. or sprayed directly into a rotary furnace.
