Title: A rotary slurry pump
IPC: F04D29/42
Filed: 1964-01-28
Abstract: 1,045,136. Centrifugal pumps. R. BAUER. Jan. 28, 1964 [Feb. 8, 1963], No. 3542/64. Class F1C. In a slurry pump, particularly for liquids containing solids, having a circular pump chamber with an intake opening on one side and a rotor laterally offset therein in the axial direction towards the other side of the chamber, the rotor diameter substantially conforms with the internal diameter of the pump chamber. Thus one side of the pump chamber rotates thereby reducing the stationary area which frictionally inhibits rotation of the liquid in the chamber. In the embodiment of Figs. 3 and 4 the radially outer ends of dished concavities 9 between rotor blades 8 are shaped to produce vortices a which couple with liquid entering at 2 and assist the pumping thereof to an outlet 3. An optional partition 13, preventing the vortices from flowing across the outlet, is curved at 14 to assist the development of the vortices. The blades 8 may be sector-shaped so that the concavities 9 are of the same width throughout their radial extent. In a further embodiment, Figs. 8 and 9, the rotor has a peripheral flange 21 and the pump casing has an optional web 22, the apex 24 of which may overlap the region of the rotor concavities 20 and is provided with a preferably arcuate recess 25 to enhance the production of the vortices. Blades 28 on the back of the rotor suppress leakage through the gap 26. The free axial ends of the blades 19 may be offset axially inwardly relative to the face of the rotor. The blades may comprise two sets of axially offset blades, the blades of one set alternating with and being of a different axial height and radial width than the blades of the other set, the free axial ends of the blades of one or both sets being inclined at an oblique angle to the rotational axis. In one construction of a flanged rotor, Fig. 13 (not shown), the peripheral wall bounding the concavities is substantially cylindrical.

Title: Improvements in or relating to scintillation screens
Inventor: PLANER GEORGE VICTOR
IPC: G01T1/20
Filed: 1954-02-06
Abstract: A screen which scintillates under the action of alpha-particles or X-ray comprises a carrier of polystyrene or polymethyl methacrylate with particles of a phosphor wholly or partially embedded therein, the screen being prepared by incorporating phosphor particles in a liquid, producing polystyrene or polymethyl methacrylate, in such a manner that a majority of the phosphor particles will be positioned closer to one of the major surfaces of the carrier then to the opposing surface, and solidifying the liquid by polymerization.  The liquid can comprise styrene monomer or methyl methacrylate monomer or partially polymerized such materials, a solution or dispersion of polystyrene in styrene monomer or in partially polymerized styrene, or a solution or dispersion of polymethyl methacrylate in methyl methacrylate monomer or in partially polymerized methyl methacrylate. Polymerization can be effected by utilizing heat, U.V. or I.R. irradiation, or pressure.  In one example, zinc sulphide is dusted over a temporary flat supporting surface of glass to which it may be bonded lightly by phosphoric acid, and a liquid consisting of partially polymerized methyl methacrylate together with a curing agent such as benzoyl peroxide is poured over the phosphor layer and polymerization completed by exposure under an I.R. lamp.  Backing plates of polymethyl methacrylate or glass are attached to the surface of the film so produced by a glue consisting of partially polymerized methyl methacrylate containing a small quantity of benzoin and the glue hardened by exposure to U.V. light.  The film is then removed from the glass plate and coated with one or more light reflecting and/or excluding metallic, e.g. aluminium, films by e.g. electrode sputtering, vaporization under reduced pressure or by transfer from a temporary supporting surface.  Alternatively, or additionally thin films consisting of a resin with a dissolved dye can be used.  In another example, the phosphor is suspended in the monomer of, or partially polymerized, styrene or methyl methacrylate with polymerization agents, and the liquid poured into a flat dish and the phosphor allowed to settle, polymerization being thereafter effected by heat and/or U.V. light.  In a further example, the phosphor is dusted over the surface of the liquid monomer of, or partially polymerized, styrene or methyl methacrylate and the liquid polymerized. Organic phosphors may be used.
