Title: Device for producing recombination radiation
IPC: H01L29/00
Filed: 1964-02-14
Abstract: <PICT:1042264/C4-C5/1> A recombination radiation device comprises a body of luminescent material 2511, either intrinsic or extrinsic conducting, means for introducing charge carriers of one type (holes or electrons) into the body, the means including a layer of insulator material 271 on the surface of the body and a layer of extrinsic semi-conductor material 291 of one conductivity type (P or N) on the insulator, and means for introducing charge carriers of the other conductivity type (electrons or holes) into the body; the insulator material has a large band-gap than the luminescent material, and a thickness which permits tunnelling, and the semi-conductor material has a band-gap which is larger than that of the luminescent material and smaller than that of the insulator.  The means for introducing charge carriers of the " other " type may be a metal plate for electrons, or an insulator-semi-conductor assembly 27, 29 as above. Preferably, the work function of the insulator relative to that of the luminescent material is chosen to be low when positive carriers are to be introduced, and high when negative carriers are to be introduced.  The device may be mounted on a transparent plate 21, and one or both charge carrier introducing means may be transparent. When using an intrinsic lumiphor, initial conductivity may be imparted by a light flash, e.g. from lamp 53, and thereafter the device may be self-sustaining. A D.C. voltage may be applied either direct to a semi-conductor layer 291, or to a metal plate 31 on the semi-conductor.  N-type phosphors disclosed are CdS: Ag, Cl (with Al, In, Cl, Ba, I, Ga as activators), CdS: ZnS, ZnSe: ZnTe, ZnO, GaP, GaN, BAs, used with an insulator of MgO, BeO, Al2O3, CdF2 or ZnF2 and P-type semi-conductors of CuI: I, BP: Be, Diamond, and SiC. P-type luminescent materials disclosed are ZnTe, ZnSe, GaP, GaAs, GaAs: GaP, and BAs, with an insulator of MgO, CdF2, ZnF2 Al2O3, BaO, Ta2O3, or ZnSiO4 and N-type semiconductor of SnO(2-x), In2O(3-x) or CdF2:Sn:Cd. The insulator layer may be 10-1000, preferably 100 <\>rA thick and the phosphor 1-1000, preferably 50, <\>rA thick.  Preparations of such devices, e.g. by vacuum deposition and heat treatment for crystal growth, activation diffusion and oxidation are disclosed. Transparent conductors disclosed include gold, SnO and In2O(3-x), and may be reinforced by a metal grid.  With a gallium phosphor, a nitride insulator layer may be formed by heating the material (e.g. GaAs) in ammonia.

IPC: B29C41/22
Filed: 1961-02-24
Abstract: In a process for the production of reinforced flexible and hollow articles formed in one piece from polyvinyl chloride and having a specific surface pattern, a layer of polyvinyl chloride is formed on a heated shaped male mould having the required surface pattern in negative form by dipping the mould in a polyvinyl chloride plastisol, or organosol, the layer is partially cured, and then a woven or knitted cotton sock of reinforcement fibres is pulled over the layer of polyvinyl chloride on the mould, and the dipping procedure repeated to cover the reinforcement with a second layer of polyvinyl chloride plastisol or oragnosol.  The plastisol is then fused and the formed article removed from the mould and turned inside out. Alternatively the layers of polyvinyl chloride may be formed by spraying.

A screen for sizing or dewatering solids comprises strips 12 of rubber or rubber-like material which are spaced apart by resilient spacers 13 and supported at intervals across their length by rods 14 which pass through holes in both the strips and spacers, the arrangement being such that the strips can be subjected to lateral compression for reducing the size of the screen openings to compensate for wear. Compression of the strips is effected by the rods 14 which pass through frame members 16 and are screwthreaded at their ends to receive nuts 17, Fig. 6 (not shown). Several such screens may be placed side-by-side, and clamped by rubber-backed plates 23 in the bottom and end wall of an inclined vibratory screening apparatus, Figs. 1, 2 and 3 (not shown) which is supported on rubber blocks 1A and vibrated by motors 10, rubber jointing 22, 29 being provided between the screens and frame and between the screens themselves.

Abstract: 1,138,285. Bearings. KARL SCHMIDT G.m.b.H. 16 Feb., 1966 [16 Feb., 1965], No. 6896/66. Heading F2A. [Also in Division B3] The sliding surface of an axial or radial bearing is provided with very slight uneveness, in order to more readily retain a lubricant film, by first hardening the surface in predetermined zones and then finish machining the surface, the different rates of chip removal in the normal and hardened zones producing the uneveness. Hardened zones 2 are formed in a radial bearing 1 by mechanical deformation, the inner bore being machined to produce the desired uneveness. The surface can subsequently be plated. The uneven sliding surface can be modified by heat treatment, the hardening step being preceded by homogenization annealing and the surface then being finish machined. Subsequent ageing at increased temperature produces a varying growth of strengthened and unstrengthened zones. The surface treatment is applicable to a composite, for example, steel/aluminium body.

Title: A method of, and apparatus for, reducing the liquid content of a material containing both a liquid and solid matter

Abstract: 1,087,197. Tubular filters for liquids; reverse cleansing. DOWTY ROTOL Ltd. Feb. 22, 1965 [Feb. 20, 1964], No. 7159/64. Heading B1D. A method of reducing the liquid content of a material comprises:-Supplying the material under pressure to a chamber, where the pressure forces liquid through a porous flexible part mounted on or in a porous or apertured rigid member and held against it by the material pressure; interrupting the supply after an interval; displacing the flexible part and rigid member and simultaneously ejecting solid from the chamber by linear movement of an ejection member; and passing a cleansing medium reversely through the rigid member and porous flexible part, the latter being lifted and flexed. In operation of the apparatus shown, material to be filtered, e.g. ceramic slip, is introduced under pressure at 30 past a valve 52 held open against a spring 53 by an extension 54 of a rod 25. The material forces open a non-return valve 55 and flows via ports 33a, 32a, into an annular chamber 37, (partly occupied, however, by three symmetrically-disposed breaker strips 38). Liquid is forced inwards through a flexible filtering sleeve, 35, e.g. of nylon, mounted on a rigid porous tube 31 of sintered bronze, to an inner annular filtrate chamber 36, and flows leftwards through ports 40 in rod 25, bore 39, drain passage 41 and drain opening 43, to atmosphere. After the supply of material has been interrupted, the rod 25 is retracted to the left (by a hydraulic jack structure mounted on a companion plate to plate 12) taking with it a piston structure 32, 33, the non-return valve 55, extension 54, tube 31, filtering sleeve 35, breaker strips 38, a valve 26 and block 22. The cake formed in chamber 37 is thus withdrawn from outer casing 28 and falls in three strips into a receptacle (not shown). The hydraulic jack structure includes a spring-closed valve with a protruding pin which is engaged by a depression 45 of block 22 in the extreme left position. The valve, thus opened, admits compressed air through a passage 42 to bore 39 and thence to filtrate chamber 36. (Drain opening 43 has at the same time been closed by abutment of its seating with a plain surface of the jack structure). This air first forces residual liquid outwards through tube 31 and sleeve 35 and then passes through these members, flexing the nylon sleeve outwards. Tube 31 may be replaced by an apertured carrier. Several such apparatuses may form a plant effecting a continuous extraction of liquid.
