Sept. 17, 1932, Nos. 25861/32 and 7123/33. [Classes 52 (iii) and 52 (v).] A reading-stand comprises a cross-shaped base, in one arm of which is a cup-like recess for receiving the leg of a chair or settee. As shown in Fig. 1, the right-angled cross-like base a has in one arm a cup-shaped hollow or recess a<1>, and in the opposite arm a socket a<2> for a telescopic pillar b, c supporting eccentrically a disc d of wood. This supports a pivoted ashtray, and also a book slope f with a page-holding device consisting of an approximately U-shaped wire h with its lower ends inturned. The book slope consists of a board f which has attached to its side edges a U -shaped bar g; the horizontal part of this bar passes under the disc d and holds the board f at the slope indicated. Fig. 5 shows a modification comprising two crossshaped bases a connected by a baseboard i. Each base has a telescopic upright b, but one carries a lamp j. The castor socket may be formed in the part i or in an extension of one of the arms of one of the cross-like bases a. In a modification, the two discs d, over which a larger tray may be inverted, are used ; the book slope may be slipped over one of the arms of the base so as to serve as a newspaper &c. holder.

Abstract: 793,911. Laminates. STANDARD TELEPHONES & CABLES, Ltd. Aug. 28, 1956, No. 26231/56. Class 140. A method of manufacturing a copper-clad laminated sheet comprises inserting sheets of a thermoplastic material and copper, of the kind hereinbelow referred to, in a mould with the rough side of the copper adjacent the thermoplastic material and heating the sheets under pressure, the temperature and pressure being sufficient to band the copper and thermoplastic material together. The kind of copper sheet to be used is that having a copper content of not less than 99.9 per cent and having one side roughened. Electrolytically deposited copper, electrolytically refined copper and heat refined copper have the required purity. If necessary, one surface of the copper sheet may be roughened by etching. Specified thermoplastic materials are polystyrene, polyvinylchloride, cellulose acetate and cellulose nitrate. Polystyrene may be sulphonated by floating in concentrated sulphuric acid before moulding in order to increase the strength of the bond with the copper sheet. A reinforcing layer of porous fabric, e.g. woven glass cloth, may be inserted between the polystyrene and copper prior to the moulding operation. As shown, a sheet of polystyrene A is placed in the cavity of a mould B with a sheet of electrolytically deposited copper C covering its upper face, the rough surface of the copper being in contact with the polystyrene. Pressure is exerted by the top part of the mould D and the temperature is raised to soften the polystyrene. Upon cooling, the laminated sheet may be removed. The laminated sheets may be used in the manufacture of printed circuits.

Filed: 1976-06-24
Abstract: 1513216 Camera bodies AGFA-GEVAERT AG 24 June 1976 [25 June 1975] 26246/76 Heading G2A A camera comprises two rectangular body parts 1, 2, coupled together by hinges 3, and which can fold over into the operative position of Fig.2, or open out into the inoperative position of Fig. 1. Part 1 contains a light opening 11 covered by an auxiliary shutter 10, the camera release 6, the film transport and shutter setting lever 4, a space for the film or cartridge, and a part 9 of the viewfinder. Part 2 contains the diaphragm, the shutter, another part 14 of the view-finder, the objective 13 and a distance setting means 18 therefor. Because of this construction the camera parts may be much narrower from back to front, so that in the Fig. I position it is thin enough to be accommodated very easily in a pocket. Each part has a grooved labyrinth construction, 12 on part 1 and 21 on part 2, of magnetic material having opposite polarities, so that in the Fig.2 position these labyrinths lock into each other to form a firm and light-tight connection. The parts may also be held open in the Fig. 1 position by a magnet on one part engaging with a magnet on the other (19, 20), Fig.3 (not shown). In the operative closed position, a pin 8 engages in a sleeve 24, so that the movement of shutter release 6 is transmitted to the main shutter to effect the exposure. Similarly a pin 5 engages in a sleeve 23, so that movement of film transport lever 4 is also transmitted to the shutter setting mechanism. The auxiliary shutter 10 (seen more clearly in Fig.5 not shown) is, in the operative position, caused to pivot and uncover the light opening when the release 6 is pressed, and held open while the main shutter operates. After exposure, it closes again, and when the camera is opened into the inoperative position it is locked, and in turn blocks the shutter release against actuation.

Abstract: 712,286. Luminescent screens. GENERAL ELECTRIC CO. Oct. 20, 1952 [Nov. 23, 1951], No. 26288/52. Drawings to Specification. Class 39(1), A method of manufacturing a cellular luminescent screen for a colour television receiver comprises immersing the screen in a liquid suspension of a first phosphor so that the screen is vertical to coat lower areas of the cell walls and then repeating the process with the screen still vertical but rotated to another position so as to coat further areas of the cell walls with a second phosphor. Preferably each cell is coated with three different phosphors the colour excited depending on the direction of approach of the beam. The green, red and blue phosphors may be manganese activated zinc silicate, silver activated zinc phosphate or zinc cadmium sulphide and silver activated zinc sulphide respectively and three electron beams may be used, one for' each colour as an alternative to a single beam. The phosphor is suspended in an aqueous solution containing 6 per cent of potassium or sodium silicate as binder and is poured into a flat sided vessel holding the multicell structure. A rough vacuum is applied to the vessel for about one minute to remove air from the cells and settling allowed to take place for about half an hour. The arrangement is then heated to 70C for an hour to precipitate the silicate binder, the solution siphoned out and water removed from the cells by blotting paper. Finally the multicell is dried in an oven. The other phosphors are applied in the same way the multicell being rotated 120 degrees each time. It is not necessary for the entire inner surface of each cell to be coated with phosphor. The cells may be of circular or hexagonal form.

Abstract: 831,240. Electrostatic separation; concentrating ores. INTERNATIONAL MINERALS & CHEMICAL CORPORATION. Aug. 26, 1957 [Sept. 26, 1956], Nov. 26817/57. Classes 82(1) and 117 A method of separating relatively non- conducting materials such as ore particles, comprises suspending selectively charged particles of the materials in a gaseous stream flowing vertically upwards between electrodes so that particles of like electric charge accumulate adjacent the electrode of opposite charge and are there collected In the apparatus shown in Fig. 1 a circular duct 10 is provided with a porous member 11 above an air inlet 12. Powdered material to be treated is fed on to the porous member from a hopper 15 and is fluidized by air rising through the porous member. The suspended, charged particles come under the influence of the electric field between electrodes 13 and 14 and are thus separated according to their charge. The fluidizing gas stream is preferably heated, e.g. in the range 90F.-500F. for separating phosphate or silica or 850F. when treating sylvinite. The use of a heated gaseous stream is preferred when materials containing excess moisture are treated. The voltage acoss the electrodes may be such as to provide a field gradient of 1000-15,000 volts per inch. The concentration of phosphate ore having a particle size in the range 14-200 mesh is referred to using a field gradient of 3000- 15000 volts per inch, also the separation of sylvinite into its components, the ore having a particle size 28-150 mesh and being treated at a temperature above 200F. using a field gradient of 1500 volts per inch. Other gases such as nitrogen, carbon dioxide or helium may be used as fluidizing media instead of air. In the modification shown in Fig. 3 the treatment chamber is of rectangular horizontal crosssection and two opposite side walls diverge upwardly to give the chamber a larger cross-sectional area at its upper end reducing the speed of particles carried upwardly by the gas stream. Baffles 37, situated in the gas inlet, and 38 and 39, between the electrodes, serve to minimize turbulence of the gas stream Particles attracted to the electrodes 32 and 30 are diverted over wedge-shaped baffles 44 and 45 to their respective receptacles.
