Title: Improvements in means for ensuring dispersion of a fluid in rotary apparatus particularly centrifugal apparatus such as that for the treatment of paper pulp
IPC: D21B1/12
Filed: 1931-01-27
Abstract: 360,283. Centrifugal machines. ROUX, C., 47, Avenue de la Motte Piquet, Paris. Jan. 27, 1931, No. 2662. Convention date, Dec. 5, 1930. [Class 23.] Fluid is supplied to a centrifugal machine through one or more orifices or nozzles ; the jets of fluid are dispersed by impinging upon surfaces which are relatively movable with respect to the nozzles. The arrangement can be used to prevent the deposition of solids or viscous substances on the walls of the machine especially during the treatment of paper pulp, or to effect physical or chemical reactions on the materials treated. A machine suitable for the treatment of paper pulp is shown in the Figure. During centrifuging, the heavy impurities are retained by the ring b and the light impurities by the ring c; the purified liquid escapes between the rings b, c and passes to the circular conduit d. Two rings h<1>, h<2> rotate with the drum, the former h<1> being in the form of a truncated cone, and the latter being a plane ring on the drum spider. Nozzles f or perforated conduits are associated with these rings. Gas, vapour or liquid can be supplied through these nozzles and after impinging on the rings h<1>, h<2> is dispersed over the various parts of the machine. Additional nozzles may be placed near the axis of the machine to direct jets on to the material under treatment. Projections on or depressions in the rings h<1>, h<2> help to break up the jets of fluid.

Title: Cathode ray tube for television
IPC: H01J31/48
Filed: 1937-01-29
Abstract: 491,443. Cathode-ray tubes; electron multipliers. RADIOAKT. GES. D. S. LOEWE. Jan. 29, 1937, No. 2678. Convention date, Sept. 11, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 30, 1937.] [Class 39 (i)] In a television apparatus an image of the object is projected on to a photo-electric screen and the resulting electron image projected on to one side of a mosaic screen consisting of an insulated wire net in the meshes of which are sensitized metal plugs ; the other side of this screen is scanned with a cathode ray or a light ray and the resulting emission utilized to produce picture signals ; either the final electron stream or the stream by which the electron image is projected on to the mosaic is amplified by secondary emission. The Figure shows an arrangement in which the photoelectric screen 1 is curved to compensate for distortion produced by the focusing electrodes 11 .. 15. The final anode 15 is at the same potential as the network of the screen 3 and the electrode 16 which accelerates the electron from the gun 64. The electrons liberated from the screen by the cathode ray are attracted by an electrode 21 into a side tube, where the stream passes through a series of secondarily emissive grids 23 .. 26, finally striking a collecting anode 17. The mosaic screen 3 is preferably produced by spraying a net of fine tungsten wire with aluminium oxide in collodion and amyl acetate, heating to 1800‹ C. in a hydrogen furnace, coating the net with powdered silver, or silver amalgam, and heating until the silver is melted and runs into the meshes of the net. The side scanned by the cathode ray is then sensitized in the usual way, and the other side coated with soot or other material which reduces the number of electrons emitted below those striking the mosaic. A construction in which the stream between the screen 1 and the net 3 is reflected at a secondarily emitting surface at an angle of 45‹ to it is also described.
