Abstract: 1,098,059. Refrigerating. LA FLEUR CORPORATION. Feb. 14, 1966 [Feb. 15, 1965], No. 6363/66. Headings F4H and F4P. In a refrigeration system at least some of the cold gaseous refrigerant from an expansion turbine is used to liquefy a gas in a heat exchanger and a minor portion of the expander refrigerant is used to pre-cool the gas to be liquefied. As shown, gaseous refrigerant from a turbine 18 is passed through a heat exchanger 24 to liquefy a pre-cooled gas passing through coil 25. The refrigerant stream is then divided into a minor portion which is used in heat exchanger 34 to pre-cool the gas to be liquefied and a major portion which is used in heat exchanger 16 to cool compressed refrigerant passing to turbine 18. The portions re-combine in line 36 and pass to the inlet of compressor 10. In a modification (Fig. 2a, not shown) the expanded refrigerant stream is divided upstream of heat exchanger 24. In a further embodiment (Fig. 2, not shown) two compressors (44 and 50) with an intercooler (48) are used, one compressor (50) being driven by the expansion turbine (60), and the gas to be liquefied is compressed in a further compressor (84) and cooled in a heat exchanger (88) before pre-cooling and liquefaction. After liquefaction the gas may be passed through a throttle (95) to a storage tank (96). The refrigeration system may include a power-generation cycle as described in Specification 1,038,575. The refrigerant may be helium and the gas to be liquefied air or nitrogen. Operating temperatures and pressures are specified.

E. ; 122, East Beechwood Avenue, Oaklyn, New Jersey, U.S.A.) Feb. 28, 1935, No. 6396. Convention date, Feb. 28, 1934. [Class 39 (i)] A photo-electrically sensitized mosaic screen 26 for use in a cathode-ray-tube, television transmitter is formed with a finely apertured wire base such as gauze 12, which is rolled flat and then insulated by an enamel 16 which enters the apertures ; the apertures are then filled with metal 24 either by pressing the material in paste or powder form, or by depositing the metal electrolytically. This may be effected on to a backing plate subsequently removed by grinding. The mesh may have 22,500 or 40,000 openings per square inch. One side of all the metal insets is then coated with photo-sensitive material 36. In a modification the screen may be formed from a thin metal sheet by a photo-engraving process ; a pattern of the apertures is photographed on a thin plate and an acid is applied to eat away the material unprotected by the photographic layer; the sheet is then cleaned, enamelled and filled with metal which is sensitized on one side. The screen substantially extends entirely across the cathode ray tube 28, the picture to be transmitted being focused from one side ; a wide-mesh, positively-charged electrode 42 collects the electrons emitted from the photo-sensitive surface. The screen is scanned on the other side by a ray 34 to develop the picture signals, the output current being taken off the screen to an amplifier 46. Electrons due to secondary emission from the screen due to the ray 34 are collected by an anode 52, which may be in the form of a silver coating on the tube and helps to focus the ray at a high speed on the screen.
