Abstract: 494,254. Television receivers. FERNSEH AKT.-GES. April 23, 1937, No. 11689. Convention date, April 23, 1936. [Class 40 (iii)] Synchronizing signals are isolated by a bridge or compensation circuit comprising a rectifier for demodulating the received signal and a thermionic diode or contact rectifier. An anode bend detector 4, Fig. 3, demodulates the received signal and forms one arm of a bridge, whose other arms are constituted by resistances 1, 2, 3. A diode 5 is connected across one diagonal of the bridge. The bridge is designed to be balanced for a signal corresponding to black, the out-of-balance potentials corresponding to blacker-than-black being of such polarity as to pass through the diode 5 and give synchronizing signals either at terminals 10, 11 or across the diode, while the outof-balance potentials due to the picture signals are of opposite polarity and are unable to pass through the diode. The circuit may be adapted for a grid-leak detector 4, Fig. 4 (not shown). In a modification, the diode 17, Fig. 5, rectifies the received signal, and its load resistance 16 is connected in series with a diode 18, load resistance 20 and potential source 19. The circuit is adjusted so that the potential applied to diode 18 is zero when the received signal corresponds to the datum separating picture signals and synchronizing signals, and that the potential is of such polarity as to allow the diode to conduct when the received signal corresponds to a synchronizing signal. The synchronizing signals are taken from across resistance 20. The demodulating rectifier may be adjusted, as by biassing, to be inoperative for atmospherics.

April 24, 1933, No. 11970. Convention date, July 26, 1932. [Class 8 (ii).] A storage container for liquefied gas is automatically adapted to discharge the gas in the gaseous state when the pressure in the container exceeds a desired working pressure and to discharge the gas in the liquid state through a vaporizer at lower pressures. At low pressures liquid is discharged through a conduit 16, Fig. 1, to heating means 17, the heated fluid passing back through a coil 18 in the container to raise the pressure therein. The gas then passes to a re-heater 19 and a reducing valve 21 which delivers the gas at a constant pressure to the consumers pipe line 23. At higher pressures, gas is delivered through a conduit 24, a back-pressure valve 25 which prevents gas passing below a set pressure and a reducing valve 27 to a conduit 28 leading to the consumers pipe line. The discharge pressure from the valve 27 is high enough to lock the valve 21. A gas storage chamber 29 and a safety valve 31 are provided. In a modification, the reducing valve 27 is omitted, a single reducing valve being set in the consumers pipe line, and the coil 18 heats liquid in a pocket in the insulating mass, communicating with the storage container by liquid and gas conduits.

Abstract: 1,018,713. Screening apparatus. A. WEHNER. March 27, 1963 [March 28, 1962], No. 12059/63. Heading B2H. A screen is provided with coupling means 6, which slidably co-operate with entraining members 4 provided on one group of bearer members 3 so as to be given an oscillatory motion by those members except when under the influence of bearer members 3<SP>1</SP> of another group; more than two driving groups may be employed. The coupling means in the form of eyelets 6 in the screen are urged downwardly by springs 7 on to pins 4 protruding from the bearer members 3. When the members 3 are given a circular motion by driving means 2, the screen is carried upwardly and then downwardly along a circular path until intercepted by stationary or oppositely-gyrated members 3<SP>1</SP> which either hold the screen in a horizontal plane or lift and lower it while the pins 4 complete their circular cycle and restore the screen to its original position. Both the bearer members 3 and 3<SP>1</SP> may be provided with rollers, yieldable teeth or combs. In Fig 13 (not shown), a half moon-shaped motion of the screen is obtained by arranging bearer members 12 of one group to gyrate about stationary bearer members 12<SP>1</SP> of another group, some of the members forming entraining members which engage slideways 14<SP>11</SP> which are secured perpendicularly to the screen 13. In Fig. 15 (not shown), bearer members 12<SP>11</SP> and 12<SP>111</SP> gyrate in the same direction about one another and are arranged to spray the screen with liquid or gas. When fine mesh screens are to be employed, they may be supported on a coarse mesh or framework which is suitable for co-operation with the drive means. The screen may be subdivided into independent strips and operated horizontally at an incline or as a stepped screen ; furthermore, the screen may be driven by a selfcleaning Umbra screen comprising bearer members fitted with lateral projections.

Abstract: 623,389. Coating metals. BRITISH THOMSON-HOUSTON CO., Ltd. April 23, 1946, No. 12231. Convention date, April 24, 1945. [Class 82(ii)] [Also in Group XL(b)] In a method of making a light sensitive selenium cell [see Group XL(b)] the selenium layer is deposited on a metal base from the vapour state at a temperature below 80‹C and the resulting deposit is pressed against a mostly planar non- metallic surface whilst the metal base is at a temperature of about 140‹C, the non- metallic surface being kept at a temperature of about 110‹C. The condensation apparatus comprises an evaporator 11 (Fig. 1), containing a quantity of solid selenium and provided with a heater, (not shown), supported in a spherical shell 12 which is maintained at a temperature of about 80‹C by means of cooling pipes 13, holders 14 being provided on the inner surface of the shell 12 whereby the base plate elements for the cells are supported. The vitreous selenium deposit which is formed on the base plate elements is subjected to pressure against a smooth non- metallic counter mould, (e.g. a sheet of freshly split mica or highly polished chemically clean glass), in the apparatus shown in Fig. 3, in which the box plate carrying the selenium is supported on a plate 21 which is maintained at a temperature of about 140‹C, (controlled to + 2‹C by the thermocouple 27), pressure being applied to the selenium surface by the counter mould 28 and the degree of pressure determined by a pre-compressed spring 31. Before the selenium coated base plate is inserted in the pressing apparatus the counter-mould 28 and the plate 21 are maintained in close contact so as to assume nearly the same temperature (140‹C). During the pressing operation, the temperature of the counter-mould drops to about 110‹C, at which temperature it is maintained by heat flow from the plate 21. In a modification of the apparatus of Fig. 1, the shell 12 is surrounded by an outer casing which is hermetically sealed except for a duct communicating with a vacuum pump and, instead of, or in addition to, the cooling by the fluid passing through the pipes 13, a cooling effect can be obtained from a highly undercooled liquid, (e.g. liquid air), contained in a reentrant cavity provided at the top of the outer casing, (Fig. 2, not shown).
