Title: Improvements in or relating to television reproducing cathode ray tubes
IPC: H01J29/14
Filed: 1939-02-23
Abstract: 525,616. Television ; cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., MYERS, L. M., and STARR, A. T. Feb. 23, 1939, No. 6079. [Classes 39 (i) and 40 (iii)] In a television receiver comprising an alkalihalide plate W of variable transparency scanned by an electron beam modulated by the vision signal, the plate is provided with electrodes AL, W for applying a potential across its thickness. These electrodes may be transparent, or one may be of opaque reflecting material. The electrodes may be formed by sputtering; that remote from the electron beam may be of tungsten, silver, or nickel, and the other of aluminium or beryllium a potential of a few hundred volts being applied across the electrodes. The halide plate may be supported on mica or heat-resistant glass and be maintained at a temperature of about 400 degrees by an oven HO or by a heating coil HE, Fig. 5, arranged between mica plates M1, and metal plates N1, MB the halide plate being mounted on the nickel plate N1. With an electron velocity corresponding to 60,000 volts, a cathode ray current of about 1,000 microamperes, a halide plate 1 mm. thick, and a.temperature of 400 degrees, the local opacity persists for about 1/25th of a second, i.e. the duration of a picture. The light from a constant source may pass through both electrodes to a screen as in Fig. 1, or may be reflected by the second electrode so that it passes twice through the crystal plate. The electron beam may fall on the same side of the plate as the light, Fig. 3 (not shown) or on the back of the plate if the light is reflected, Fig. 4 (not shown). The crystal plate may be grown from a solution or from a melt. Reference has been directed by the Comptroller to Specification 513,776.

Title: Improvements in or relating to the manufacture of lay figures
Inventor: SCOTT PAULINE
IPC: A41H3/04
Filed: 1963-02-14
Abstract: 1,090,111. Lay-figures. MARKS & SPENCER Ltd. April 29, 1964 [Feb. 14, 1963], No. 6092/63. Heading G5G. A method of manufacturing a lay figure comprises the steps of applying to the human body a close-fitting covering of butter muslin or nylon jersey, applying to such covering a stiffer material such as a masking tape or pregummed strips of brown paper to produce a hollow pattern conforming to the configuration of the person, cutting open the hollow pattern for removal and after rejoining removing the hollow pattern and using the pattern to produce the lay figure by moulding or casting techniques. To facilitate removal of the pattern the original covering may be provided with zip fasteners along e.g. shoulders and sides. The ability of the pattern to retain its shape during handling and production is enhanced by spraying it with suitable varnishes or paints. The pattern may also be reinforced by a coating of plaster of Paris to make a mould. The lay figure may then be produced by sewing the pattern into half moulds filling the half moulds with papier mÔchÚ and placing them together before the mÔchÚ sets. The lay figure may be provided with a surface layer of material which permits pins to be stuck into. Readily deformable parts of the human body e.g. female breasts may be made of deformable material such as foamed rubber or sponge. The lay figure may have detachable limbs and may be divided to cater for asymmetries of the human body.

Abstract: 127,618. Jones, J. H. April 30, 1917. Processes, special.-Consists of a process for rounding angular edges or recesses, particularly applicable for rounding the crests and roots of hardened screw gauges. A curved surface uniting two mutually inclined surfaces is produced by preparing a number of pairs of such inclined surfaces to constitute a series, the sides being produced to form angular edges or recesses, and applying to these angular edges or recesses. one after another in succession, an abrading-surface the working face of which is flat for a crest or has a V-edge for a recess, until, by repeating the successive applications of the grinding-tool, the tool is worn so hollow or so round that the crest or recess last ground by it receives substantially the desired curved form; the remaining partly ground edges or recesses of the series are finished with the tool thus worn to shape. The grinder may be a wheel or other tool, and the process may be applied for rounding the angle between a single pair of inclined surfaces. Figs. 3, 4, and 5 show steps in the process of rounding the crests of the thread of a screw gauge.

Abstract: 105,055. Naamlooze Vennootschap Neo-Cellulose Maatschappij. lfarch 23, 1916, [Convention date]. Addition to 24057/12. Pulp, preparation of.-In separating impurities from fibrous materials, particularly in forming clean pulp from waste paper, by agitation with two immiscible liquids as described in the parent Specification; the agitation is carried out so as to produce a layer of foam which takes up the impurities. When water and a hydrocarbon are used as the two liquids, the foam is stable, and the whole of the hydrocarbon may be contained in it. In place of a hydrocarbon, a stable foam may be obtained by the use, in conjunction, of a material to form a foam such as soda soap, and a material to render the soap-foam stable such as vaseline, animal or vegetable fats or mixtures such as margarine. The soap used in forming the foam may be used for the preliminary treatment of the fibrous materials in place of sulphides, sulphites, thiosulphates or thionates.

IPC: F04F13/00
Filed: 1960-02-26
Abstract: 897,041. Pressure exchangers. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Feb. 7, 1961 [Feb. 26, 1960], No. 6827/60. Class 8(1). [Also in Group XIII] In a combined heating and cooling plant including a pressure exchanger 1, a compressor 13 and a heat processing chamber 11, a substance, for example tea leaf, is heated and dried in the chamber and cold air is provided for ventilating purposes. The pressure exchanger has a ring of cells 2 which rotate in a direction A relative to ports 3 . . . 6. Air at one atmosphere pressure and, say, 30‹C., enters the exchanger 1 through the inlet port 3 and flows into the cells 2 which at that instant are opposite the port. The cells already contain air at a pressure slightly less than one atmosphere and this air is compressed by the entering air to a pressure slightly greater than one atmosphere and heated to a temperature of, say, 85‹C. As the cells reach the outlet port 4 the heated air flows therefrom through the port and a line 10 to the chamber 11. The air remaining on the cells expands, its pressure falling to 0À55 atm. and its temperature to, say, -15‹C. When the cells reach the port 6, the air expands further and flows through the port and a line 7 which may include a water separator to a heat input stage 8 wherein the air is brought into indirect contact with brine entering a coil 9 at 30‹C. The brine leaves the coil at, say, -5‹C. and is used for cooling ventilating air. In a modification the coil 9 receives hot air exhausting from the chamber 11 instead of brine. Air leaves the stage 8 at, say, 20‹C. and part flows via a line 7 to the inlet port 5 whence it enters the cells 2 behind the air discharging through the port 6. The cells leaving the port 5 contain air at a pressure slightly less than atmospheric. As they move into communication with the inlet port 3 the cycle is repeated. The remainder of the air flowing from the stage 8 passes to the compressor 13 wherein it is compressed and heated. It discharges through a line 16 to mix with the air entering the chamber 11 through the line 10.
