Title: Improvements in sound television receivers
IPC: H04N5/62
Filed: 1954-02-23
Abstract: 753,030. Multiplex radio signalling; automatic gain control. GENERAL ELECTRIC CO. Feb. 23, 1954 [Feb. 24, 1953], No. 5321/54. Class 40 (5). In an intercarrier sound/vision radio receiver, the audio carrier energy reaching the second detector from a wide-band audio and video carrier amplifier is varied according to the amplitude of the beat frequency output of the detector, by controlling means for absorbing such energy from the amplifier. In the embodiment described the R.F. and frequencychanger stage 4 and the I.F. stages 6, 10, 8 feed the second detector 12, which provides the video signal for the picture tube 16 and feeds the sync. separator 18 controlling the scanning circuits 20, 22. The second detector output is also connected to the circuit 32, 34 which is series resonant to the inter-carrier beat frequency 4.5 M/cs. A tapping on inductance 34 is connected through capacitance 78 to a pentode limiter 72, the output of which provides the audio signal in discriminator 40 to energize the reproducer 44. The output of the I.F. stage 10 is developed across a circuit 48, 50, tuned to the audio carrier frequency, some of the energy in which is absorbed by a circuit 52, 54 magnetically coupled thereto and similarly tuned. In order to vary the amount of energy absorbed by circuit 52, 54, the capacitance 54 is shunted by a series circuit comprising capacitances 60, 62 and a diode 58, the junction of 60, 62 being earthed. The diode is normally biased to cut-off by a fixed positive voltage from potential divider 64, 66 applied to its cathode. Application of a variable positive voltage to its anode, over lead 70, renders it conducting to a variable degree. This control voltage is derived from the cathode resistance 79 of the limiter 72, the current through which varies with the amplitude of the beat-frequency applied to the grid, as the timeconstant of capacitance 78 and grid resistance 80 is such that the valve acts as a grid-cathode limiter. The changes in beat-frequency amplitude are made a function of the sound carrier alone by known gain control circuits applied to the video carrier.

Patent GB-395641-A (GB)
Title: Improvements in or relating to the separation of gases
IPC: C01B17/56
Filed: 1933-02-23
Abstract: A condensable constituent of a gas mixture, e.g. sulphur dioxide in furnace gases or volatile hydrocarbon in petroleum gases, is recovered by dividing the gas mixture into two portions one of which is cooled by expansion of cold stripped gas, and the other by evaporation of liquid.  The gas mixture is compressed and dried and one portion passes through an exchanger 16 cooled by cold gas, the condensate formed being drawn off into a receiver 26.  The second portion flows through an exchanger 17 cooled by evaporation of liquid drawn from the receiver, or from the base of the cold gas exchanger, the vapour being drawn off by a compressor 30 cooled by a coil 31 and returned to the storage tank.  The condensate from the exchanger 17 flows into the tank. The stripped gas from this exchanger is expanded in a motor 41 and flows through a separator 42 to the exchanger 16, liquid from the separator passing to a vessel 45 from which it may be conveyed to the tank or the exchanger 17.  The gases from the exchanger 16 may pass to the motor 41 or may be expanded directly around the <PICT:0395641/III/1> tubes of the exchanger 16.  In treating lean mixtures, the exchanger 17 may be used merely as a byepass conveying unstripped gases to mix with the stripped gases from the exchanger 16 in the motor 41.

Abstract: 1,220,803. Bakery apparatus. BAKER PERKINS Ltd. 1 Feb., 1968 [8 Feb., 1967], No. 6039/67. Heading A2A. [Also in Division B8] Receptacles 5 having cavities 6 for the manufacture of meat pies, and conveyed on a belt 7, have a linear cam formation 10 adapted to co-operate with cam follower means 9, thereby to control the operation of pie blocking apparatus (not shown). As the receptacle 5 approaches the blocking station, it is sensed by an inductive proximity switch (not shown). The latter acts to move valve 14 into its full-line position thereby energizing cylinder 12 thus releasing stops 12A holding arms 8. The latter are then urged inwardly so as to engage followers 9 with notches of the cams 10. Arms 8 respectively reverse a valve 16 and operate a switch 18. The valve 16 reverses a valve 15 to supply pressure to cylinders 13 for firmer holding of the arms 8. Switch 18 initiates the blocking operation. The cylinders 13 may be of different dimensions in order to provide a positive means of lateral location of the tray. At the end of the blocking operation a limit switch (not shown) deenergizes the valve 14 to initiate release of the tray. Similar apparatus is employed at a meat filling depositor station (not shown) and at a lid cutting and crimping station (not shown). In another embodiment (Fig. 1, not shown), the trays are adapted to carry a series of six bread tins. A cam follower (3) engages depressions (2) respective to each tin. The follower in addition to initiating the operation of a depositor (4) may cause the conveyer to stop. Alternatively the conveyer may run continuously, the trays being held in slipping contact with it during filling.

Abstract: 936,626. Reactor shields. GENERAL ELECTRIC CO. Feb. 22, 1960 [Feb. 24, 1959], No. 6133/60. Class 39 (4). To prevent the release of toxic products after the rupture of a nuclear reactor pressure vessel, the products are passed through the biological shield into a liquid pool surrounding the shield. As shown, the pressure vessel 10 is supported in the dry well 32 within the biological shield 30 which is surrounded by the liquid 40. The vent tubes 60 are provided with rupture discs 62 and join 32 to the annular air pocket 64. A leakage from 10 is first contained in 32 until the pressure rises, and the discs 62 give way to permit discharge into 40 through 64. In the pool, the leakage fluids are condensed and dissolved and the baffles 78 increase the contact between the pool liquid and the gas phase. To prevent melt down of the core, pool liquid is directed into the pressure vessel through tubes 90 by the remotely controlled valves 92. In a second embodiment, not shown, the toxic products in the dry well are passed to the pool through vent tubes which lead from the upper volume of the well radially outwards and then vertically down through the liquid surface. The pool liquid is alkaline, and contains boron to prevent nuclear reaction in the core after flooding. The liquid may be water, alcohol, glycol or glycerols.
