Title: Improvements in or relating to electron discharge devices
IPC: H01J43/10
Filed: 1955-05-27
Abstract: 792,507. Electron multipliers; cathode-ray tubes; electrode materials and processing. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 27, 1955 [June 4, 1954], No. 15355/55. Class 39(1). An electron multiplier, e.g. for light, infra-red or X-ray image intensification, comprises an envelope 10 having therein at least one planar dynode 17, 18, 19 positioned between a planar cathode 15, e.g., thermionic or photo-emissive, and a planar target 16, e.g. fluorescent, each dynode comprising a unitary metallic grid structure 42 formed with a plurality of tapering cellular openings 43 therein, the sides 44 of the openings diverging towards the cathode, and wherein the face of each grid structure remote from the cathode supports a thin continuous layer 40 of a crystalline insulating material such as an alkali halide, e.g. potassium or sodium chloride, which has the properties of producing secondary electrons transmissively and of increased conductivity upon electron bombardment. The layer 40 has a thickness of the order of 10<SP>-7</SP>-10<SP>-6</SP> cms. and is positioned on a layer 41 of electrically conductive material having a high atomic number, e.g., gold or uranium, and having a thickness of approximately 10<SP>-6</SP> cms. or less, causing scattering of incident electrons into the layer 40. The photocathode 15 and fluorescent target 16, e.g., of zinc sulphide, can be positioned on transparent conducting coatings 20 and 21 of Nesa. Alternatively the fluorescent target 16 can be provided with a thin aluminium coating. Equal steps of voltages can be applied between the electrodes 17, 18, 19 and 16 or the image electrode 16 can be operated at a substantially higher voltage. The grid 42 is of copper or nickel and can be plated or coated with gold or platinum. The openings 43 of the grid can be etched in a sheet of material so as to provide 500 openings per inch and an open area grid of about 50 or 70-90 per cent. The dynodes 17, 18, 19 can be formed by covering the grid with water and applying an organic solution, e.g. of Zapon, to the surfcae of the water. The water is removed and the organic film allowed to settle on the grid. The organic film is dried, the metal film 41 and secondary emissive layer 40 evaporated thereon, and the organic film baked off. The metal film 41 can be used with alkali halide layers 40 of lower atomic number but omitted with those of higher atomic number. Alternatively the layer 40 can be deposited into a permanent film of material such as SiO<SP>2</SP> of thickness of approximately 10<SP>-7</SP> cms. previously deposited in a manner similar to that for the organic film. The dynodes 17, 18 and 19 can have a close spacing of the order of a few tenths of an inch. The dunodes 18, 17, 19 may be mounted at different angles to the direction of incidence of the electrons whilst making the layer 40 thinner. Each dynode may be of a double grid construction and the secondary emissive material may extend to the sides of the second grid.

Filed: 1926-06-18
Abstract: 280,611. British Hartford-Fairmont Syndicate, Ltd., and Wardley, T. June 18,1926. Delivering molten metal.-Apparatus for feeding molten glass from a receptacle through a discharge opening comprises means for moving the glass positively in a plane substantially at right angles to the axis of the discharge opening in order to keep the glass of uniform temperature and consistency. In the construction shown in Fig. 1, the molten glass is contained in a forehearth A and is discharged through an opening B by the reciprocations of a plunger C, the size of the charge of glass being regulated by a flow-controlling tube surrounding the plunger, as described in Specification 194,675. According to the invention, another tube E surrounds the tube D and is provided on its outer surface with projections, vanes, or fins E'. The tube is rotated or moved angularly, and the projections E<1> stir or move the glass. The tube E may be dispensed with and the projections E' may be formed either on the tube D or on the plunger C when the tube D is not used. In another construction, the tube E may be provided with internal projections or it may be formed with spaces that leave depending parts dipping into the glass. The tube E may be adjusted vertically, if desired, to enable the stirring movement to be imparted at any desired depth in the glass. When the tubes D, E are not used, the plunger C is provided with a worm wheel F, Fig. 7, which is engaged by a worm on a spindle H journaled in a frame carried by the plunger. A pinion J secured to the spindle engages one or the other of two parallel racks L, M formed on the interior of the frame K which is movable horizontally. The frame is moved in unison with the reciprocations of the plunger C so that the pinion H is engaged by the racks alternatively on its downstroke and on its upstroke. The plunger is thus rotated continuously and the projections C' stir the glass.

Title: Polyhydroxynaphthacenes and their preparation
Inventor: MCCORMICK JERRY ROBERT DANIEL
IPC: C07C233/00
Filed: 1962-11-05
Abstract: The invention comprises naphthacene compounds of the formula <FORM:1026774/C2/1> wherein R2 is hydrogen, carboxamido, or N-(C1-C6 alkyl) carboxamido, R4 is hydrogen or dimethylamino, R5 is hydrogen, R7 is hydrogen, halogen or hydroxy, and R8, R9 and R10 are each hydrogen or hydroxy, and of the formula <FORM:1026774/C2/2> wherein R2 is carboxamido or N-(C1- 6 alkyl)-carboxamido, R4 is hydrogen, R7, R8, R9 and R10 are as defined above, or tautomers thereof, and of the formula <FORM:1026774/C2/3> wherein R2 is carboxamido or N-(C1-C6 alkyl) carboxamido, R4 is hydrogen, R1 is hydrogen or C1- 6 alkyl, R7, R8, R9 and R10 are as defined above, or tautomers thereof.  The novel compounds may be made by condensation of an appropriately substituted phthalic anhydride with a substituted 1,3-dihydroxynaphthalene under Friedel-Crafts conditions to form either a 6-hydroxynapthacene-5,12-quinone (II) when the dihydroxynapththalene contains a hydroxy or alkoxy group in the 5-position, or a naphthacene-6,11-quinone when there is a hydrogen atom or C1-C6 alkyl group in the 5-position. The naphthacenequinones may be reduced to the corresponding compounds of Formula I, for example with a metal and acid, hydriodic acid, catalytic hydrogenation, metal and alkali, reducing salts, or metal couples. The novel compounds may also be made by condensation of a substituted naphthalene with a substituted 3,5-dihydroxyphthalic anhydride to form the 6-hydroxynaphthacene-5,12-quinone which is then reduced as above. In these preparations, the phthalic acids, esters and halides may be used in place of the anhydrides.  The 2-carboxamide group may be introduced after the reduction of the naphthacene-quinone by use of the Gatherman-Koch or Reimer-Tieman procedures to prepare the 2-aldehyde which is converted to the amide via the oxime and nitrile. Alternatively the 2-acetyl derivative may be converted to the amide via the carboxylic acid or ester.  Compounds of Formula I in which R4 is dimethylamino or R4 is dimethylamino and R7 is chloro are made (in examples) by treating 6-dimethyltetracycline (or its 7-chloro derivative) with acetic-formic anhydride to give the corresponding 6-demethyl-12a-O-formyltetracycline; the latter is distilled in xylene solution forming 6-demethyl-4a,12a-anhydrotetracycline which is dissolved in butanol and HCl and heated on a steam bath to give the desired product.
