Title: Luminescent detectors of nuclear radiation
IPC: G01T1/204
Filed: 1951-05-02
Abstract: 688,672. Luminescent materials; photo-cells. TESLA, NARODNI PODNIK, KUHN, A., and KMENT, V. May 2, 1951 [May 13, 1950], No. 10272/51. Class 39(i) [Also in Group XL(b)] Radio-activity is detected by means of a liquid which fluoresces under the radio-activity the secondary radiation from the liquid being detected by either a photo-cell or a Geiger counter sensitive to visible or ultra-violet light. In the example shown in Fig: 3 the cell 5 is situated in a recess in a globe 2 reflecting on its outside or inside surfaces and filled with a liquid which under the influence of radio-activity emits ultra-violet radiation. This radiation after reflection from the coating of the globe is converted into radiation of a longer wave-length by a cube 13, the cathode of the photo-tube receiving light through an uncoated part of the recess wall. In the embodiment of Fig. 2 (not shown) the cube is omitted while in that of Fig. 1 (also not shown) the reflecting coating is omitted from the cell recess and a Geiger tube is situated in the recess. In the embodiment of Fig. 4 for determining alpha radiation the radioactive substance 8 is placed in a tube 9 radiation passing through a wire disc 10 into the fluorescent liquid 1. The fluorescence is then reflected from a parabolic reflector and concentrated by a lens 6 on to the cathode of a cell 5. In detecting neutron radiation the reflector is coated with a substance such as cadmium or indium which emits secondary Alpha, Beta or Gamma radiation. The Specification mentions four distinct types of fluorescing liquids (1) Luminescent liquids emitting ultra violet rays (2) Solutions of luminescent substances in solvents having no luminescence e.g. UO 2  (NO 3 ) 2  in water or naphthalene in ether. (3) Solutions of luminescent materials in luminescent liquids emitting radiation of different wavelength from the solids e.g. stylbene in benzene (4) Solutions of luminescent material in liquids emitting radiation of the same wavelength as the solids e.g. naphthalene in benzene.

Title: Selenium cell and lacquer therefor
IPC: H01L21/145
Filed: 1943-06-25
Abstract: <PICT:0583170/IV/1> A lacquer for application to a selenium cell or current rectifier comprises cellulose acetate and selenium dioxide in a volatile liquid.  The lacquer is applied to the selenium surface so that upon drying a layer is formed which enables the voltage across the cell to be increased, and where the cell is used as a rectifier the undesirable reverse current is reduced.  Only a very little reduction of the forward conductivity is produced by the lacquer coating.  As shown in Fig. 1, a current rectifier comprises a base plate 1, which may be of steel, on which is placed a layer of selenium 2.  The selenium may be applied by spreading molten selenium over the base plate and allowing it to cool and solidify.  The selenium is annealed by heating for some time at a temperature below the melting point to induce crystallization and enable the cell to operate as a rectifier.  The selenium coated disc may be placed in a press and heated to 120 DEG  C. for 30 minutes, and then heated to 214 DEG  C. for several hours after removing the pressure.  A layer of the cellulose acetate lacquer is applied to the annealed selenium and then a counter-electrode 3 is applied over the lacquer layer by spraying on a metallic alloy such as an alloy of cadmium, bismuth, and tin.  In an example, a thin lacquer comprising cellulose acetate, selenium dioxide, methyl ether of ethylene glycol acetate, and ethyl alcohol, is prepared.  The lacquer is applied by brushing or spraying, and on drying there is formed a very thin coating on the selenium surface.

Abstract: 358,526. Filter-presses. WILDERMAN, M., Villa Meurice, Rue Bosio, Monte- Carlo, Monaco. April 3, 1930, No. 10551. [Class 46.] Relates to filter-presses with double filter plates each composed of two plates, held apart to form a filtrate chamber and one or both of which are provided with ribs or projections so that the single plates give each other mutual support against the filtering pressure. According to the present invention the ribs or projections are formed of porous material. The plates may be formed of porous ebonite or soft-to-hard rubber with projections of the same material. Fig. 1 shows a single plate with lugs 1 .. 4 having apertures b .. g, which form mains for the supply and discharge of liquid under treatment, wash liquor, air, &c. The plate is provided with vertical projections 6 which contact, when the plates are in position, with the surface of the companion plate or with similar projections thereon. There may be similar horizontal projections 9, but these do not project sufficiently to prevent the downward passage of the filtrate within the double element. The plates may have metal frames 10, Fig. 9, with a coating of non-porous ebonite 10a. The frames may be moulded first and the plates moulded of partially vulcanized rubber within the frames, vulcanization being completed afterwards. Or plates and frames may be moulded separately and subsequently united by means of strips 8a, Fig. 12, of rubber coated with rubber solution which are afterwards vulcanized. Instead of rubber strips, strips of celluloid softened in acetone vapour and coated with a solution of celluloid in acetone may be used, a solid joint being formed on evaporation. Joint between the frames of the plates is made by means of rubber strips having a leather-like non-compressible layer and a layer of flexible rubber. The non-compressible layer is fixed in a groove in one frame and the flexible layer is pressed into a groove in the adjacent plate.
