Title: Improvements in or relating to gas or vapour filled electric discharge tubes
IPC: H01J61/067
Filed: 1936-03-26
Abstract: 472,648. Thermionic cathodes. CLEVELAND, F. J. (Oerensofi, N. S.) March 26, 1936, No. 9060. [Class 39 (i)] An electrode of the hot cathode type for a gas or vapour-filled discharge tube has a conductive carrier portion and an emitting coating covering a substantial proportion of its surface, the carrier portion being formed with apertures, extending from the coated to the uncoated surface thereof, from which canal rays are emitted during operation of the discharge tube containing the electrode. The electrode shown comprises a thin strip 14 of tungsten bent into an arc and coated on one side with emissive material 16. Perforations 15 are provided, which in operation are free from emissive material and permit the passage of canal rays. Two such electrodes are mounted at the ends of a discharge tube with the coated concave faces inwards, so that the canal rays may be directed towards the cool ends of the envelope to prevent condensation and to maintain the filling in circulation. The emissive coating is of material which becomes conductive only at a temperature above that at which it becomes emissive. Such a material may comprise, by weight, zirconia 75 per cent, yttria 15 per cent, barium oxide 8À5 per cent, and strontia 1À5 per cent, together with a binder such as potassium waterglass or an easily vaporizable organic or inorganic compound. The binder may be replaced by 50 per cent or less of barium hydroxide. When chemically active gases, such as nitrogen, carbon dioxide, sulphur, selenium or tellurium are employed, the carrier should be of resistant metal such as gold or platinum, or these metals may be coated upon a base metal, such as tungsten, molybdenum, chromium, tantalum or nickel, electrolytically or by decomposing their chlorides. As carbon dioxide attacks alkaline earths, with this filling a mixture may be employed comprising zirconia 75 per cent, erbia 17À5 per cent, thoria 6À5 per cent and ceria 1 per cent. To secure a firm attachment of the emissive coating to carriers of metal or carbon, addition may be made to the emissive mixture of a metal such as zirconium, magnesium or thorium or a substance such as silicon which will alloy or combine chemically with the carrier substance. To a mixture of yttria 75 per cent, thoria 20 per cent, and barium oxide 5 per cent may be added four times its weight of zirconimn. When heated in vacuo or in hydrogen, the zirconium alloys with the tungsten carrier and partially reduces the oxides to form zirconia which is concentrated at the surface. The apertured carrier may be of spiral, helical or other twisted form. Specification 441,250 is referred to.

Title: Improvements in or relating to colliery and like "overwind" gear
IPC: B66B5/08
Filed: 1933-03-30
Abstract: 415,191. Winding - apparatus. HEWITT, H., Hill Side, Tunnel Road, Ansley, Nuneaton. March 30, 1933, No. 9554. [Class 78 (v).] A colliery or like winding gear is provided with hydraulic mechanism controlled by a timing device for stopping the engine and applying the brakes if overwinding occurs or a safe speed is exceeded. The mechanism includes a dash-pot device for cushioning the automatic application of the brakes. An oil pump, not shown, driven by the winding engine, forces oil from a sump 2 through a pipe 3 and the cylinder 5 of a piston valve 6 and back to the sump through a pipe 4. The valve 6 has a stem 7 carrying, on a pin 17, a roller 10 in engagement with a cam 8 which is so driven by the engine that it makes less than a complete revolution for the complete travel of the cage. An extension of the pipe 3 is connected to the upper end of a cylinder 11 in which is a piston 12 having a stem 15 with adjustable stops 15a for engaging a lever 16 pivoted on the pin 17. The uppermost position of the piston 12 under action of a spring 13 is defined by an adjustable stop 14. The lever 16 normally holds from turning a pivoted arm 19 which is linked to arms 23, 24 which are operatively connected respectively to brake-applying and enginestopping mechanisms and which are biassed by weights. For most of a winding operation, the passage for oil through the cylinder 5 is unobstructed. Towards the end of an operation, however, the cam 8 elevates the piston 6 partly to close the passage, so that the increasing pressure in the pipe 3 forces down the piston 12 and, eventually, rocks the arm 16, which has risen during this time with the piston rod 7, freeing the arm 19 and causing the engine to be stopped and the brakes to be applied. Similarly, excessive winding speed increases the pressure developed by the oil pump and so stops the engine. The cam 8 is provided with a projection 8a designed to stop the engine if the latter is started to drive in the wrong direction. A branch 3a from the pipe 3 is connected to a cylinder 29. When pressure develops in the pipe 3, it forces down the piston 31<a> so that a roll 32 on its stem 31 is in position to engage and cushion the movement of an arm 33 carried by the rock shaft 34 of the brake-applying arm 23.
Patent GB-454023-A (GB)
Title: Improvements in or relating to the cooling of vapour electric converters
IPC: H01J13/32
Filed: 1935-03-27
Abstract: 454,023. Arc converters. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Ltd., Witton, Birmingham. March 27, 1935, No. 9566. [Class 39 (i)] The metal container of a vapour electric converter is cooled by a number of streams of gaseous fluid, each stream being adapted to flow across a relatively short path of the container in a turbulent manner so that the major part of the pressure drop occurs at the container. Air is blown from a space below the converter by a fan through ducts 4, Fig. 1, in through gaps 12 in a sectional jacket 3, across the surface of the container 1, and out through gap 9. The jacket is closed at the top and bottom by plates. The radial depth of the ducts may decrease towards the top and bottom and air from the jacket 3 may pass through channels in the top plate of the converter. Longitudinal ribs may be provided on the converter to guide the air streams. In a modification, one side of the ducts 4 may be extended to the container so that air therefrom can flow in one direction only around the container. When the converter is relatively long, air is supplied to the centres of the ducts 4, Fig. 5, through a header 15 and two pipes 14 from the chamber 5. Air is also guided by a member 15<1> over the bottom of the converter and additional air may be fed to the bottom of the ducts. When the converter is provided with anode arms 17, Fig. 7, the outlets 18 of the surrounding jacket 3 are provided with radial flanges to direct the air into the arms. The outlets 18 extend upwardly to the horizontal plane which contains the top of the arms to prevent cooling of the anode seals 20. A flange 21 on the jacket directs air over the top plate 16. The air chamber 5 rests on insulators 23 and is provided with inwardly extending vanes which guide the air from the fan 24 and support the converter. The ducts 4 which supply the jacket 3 are arranged between the anode arms and are integral with the jacket 3. Air is fed to the ducts from chamber 5 through ducts 25. The chamber 5 is formed with openings 26 from which air is directed onto the arms by spouts 27. The cathode lead is taken through a bushing 29. The fan motor is insulated from the converter by forming the propeller of insulating material, or by providing a clearance between the tips of the propeller and the walls of the chamber 5 or by lining the chamber 5 with insulating material and it may be located in the throat of a convergentdivergent chamber 5. In another form, air is fed from the chamber 5, Fig. 8 through pipes 35 to circumferential headers 34 from whence it flows axially across the container through circumferential ducts 33 and out through gaps 36 located between the ducts. Air is directed over the bottom of the converter by a jacket 37. In another form, the air which issues from the jacket is directed by a further jacket over the condensing dome which may be further cooled by additional air from the chamber 5.

Title: A process and apparatus for heating sugar containing materials
IPC: C13B10/08
Filed: 1964-03-06
Abstract: In a process and apparatus for heating sugar beet cossettes before they enter a diffusion device 20, Figs 1 and 2, the cossettes are fed, by a conveyer 1 and through a hopper 2, on to the upper flight of a permeable, e.g. perforated, endless travelling conveyer belt 4 supported by drums 5. A regulator 6 and side baffles 7 maintain a uniform layer of cossettes on said upper flight.  Juice-distributing, perforated surfaces or sprinklers 10 are provided above said upper flight and a juice-collecting tank 11 is provided below it. The conveyer assembly 3 is pivoted at a point 13 and mounted on a jack 14, so that the upper flight of the belt 4 can be tilted. The conveyer assembly 3, the sprinklers 10 and the tank 11 are disposed within a casing 15, which is provided with an outlet pipe 17 connected to an inclined duct 18 leading into the diffusion device 20. A device for cleaning the conveyer belt 4 is provided. This device may comprise nozzles 8, for directing air or pressurized fluid at the belt, or a brush 9 rotating in the opposite direction to that part of the belt which it engages. Hot juice is withdrawn from the diffusion device 20 through a screen 21 and a pump 22. Part of this juice is sprinkled, by the sprinklers 10, on to the layer of cossettes and passes through the cossettes-thus heating them-into tank 11. The remainder of the hot diffusion juice is passed through a heat-exchanger 23, to acquire a desired sterilizing temperature, and then through a pipe 16 to mix with the heated cossettes received in the pipe 17. The resulting mixture passes into the diffusion device 20 through the duct 18, which is of such a length that a desired exchange of heat takes place and the cossettes are rendered aseptic. The final diffusion juice issuing from the diffusion device 20 and the juice from the tank 11 are subjected to further sugar-manufacturing processes. In order to isolate the conveyer belt, so that it can be stopped and repaired, a pivoted distributer 27 Fig. 3 (not shown), provided in the hopper 2, is operated to deflect cossettes away from the belt into the bottom of the casing 15 near the pipe 16, which is connected to the lower part of the casing at its inlet end. <PICT:1048326/C6-C7/1> <PICT:1048326/C6-C7/2>
