Abstract: 458,654. Television. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Hefele, J. R., and Ives, H. E.) June 2, 1936, No. 15402. Convention date, May 31, 1935. [Class 40 (iii)] In a colour television system, an object O is scanned at the transmitter T by a disc 12 having three apertures 1, 2, 3 in place of each aperture of the usual single spiral, all the apertures of spiral 1 being covered with red filters, those in spiral 2 with green filters and those in spiral 3 with blue filters. The light reflected from the object O is impressed on photo-electric cells 17, 18, 19 which are either inherently colour selective or made so selective by the provision of filters 20, 21, 22. If desired, a plurality of groups of colour selective lightsensitive cells may be employed. The image currents produced by the cells are transmitted over separate channels and applied at the receiver R to strip light sources 29, 30, 31 which either inherently produce light radiations of the different wavelengths or colours or have associated therewith appropriate filters 32, 33, 34. The light from these sources is directed on to a mirror helix 37 constructed as described in Specification 402,401, the light being reflected from the helix on to an observer's eye E. The spacing apart of the apertures in the disc 12 is determined so as to compensate for the physical separation of the light sources at the receiver and so obtain superimposition of the three images. According to a modification, Figs. 7-9 (not shown), a lenticular photographic film, preferably prepared by the process known under the Registered Trade Mark " Kodacolor," is scanned at the transmitter and delay networks are inserted in the channels leading to two of the light sources at the receiver in order to obtain superimposition of the images. The delay networks may alternatively be inserted at the transmitter or at any point in the transmission lines. If desired, the mirror helix 37 may be replaced by a lensed disc or other similar scanning device.

A diamond nuclear radiation detector is provided with a carrier-injecting electrode 2 and a blocking electrode 3, the thickness of the diamond 1 between the electrodes 2, 3 being less than the maximum attainable carrier diffusion length. The carriers injected by the electrode 2 serve to fill deep traps in the diamond 1 and thereby counteract polarization effects during long irradiations. The type of diamond used (type IIa or intermediate type) contains relatively little nitrogen impurity. In a second embodiment the diamond has a recess and the thickness of the crystal at the bottom of the recess is less than the maximum attainable carrier diffusion length, the remainder of the crystal being thicker. Injecting or blocking electrodes may be formed by painting on Au, Ag or Pt and heating at 500-700 C., by applying a solution of Au, Ag or Pt salts and heating at 500-700 C. or by doping the diamond surface with B, Al, P, Li or C. Electrodes which inject both electrons and holes may be formed by coating the diamond with a colloidal graphite suspension and treating in vacuum to 500-600 C. Blocking electrodes may also comprise evaporated Au, Ag or Pt, or may be formed by graphitizing the diamond surface in vacuum at 1000-1300 C. and removing the graphite from all surfaces except that on which the blocking electrode is required. Prior to application of the electrodes the diamond may be annealed in vacuum at 1000-1300 C. to increase the carrier lifetime, and etched by an oxygen-containing medium to reduce surface recombination.

Abstract: 691,261. Air and gas heating furnaces. ENGLISH ELECTRIC CO. Ltd. June 22,1951 [June 23,1950], No. 15742/50. Class 64 (i) [Also in Group XXVI] A turbine power plant for burning a low concentration combustible gas-air mixture such as methane in upcast air from coal mines, comprises a blower for supplying the mixture to a combustion chamber having a direct contact regenerative heat-exchanger transferring heat from the exit to the entrance of the combustion chamber and a compressor supplying air, which is at least partly heated in a heat-exchanger in the combustion chamber, to a turbine. In the arrangement shown, upcast air is delivered by a blower 5 to a rotary regenerative heat-exchanger 6 where it is heated before passing over heat-exchanger tubes 8 into the combustion chamber 9. The combustion gases pass over further heat-exchanger tubes 8 and through the rotary heat-exchanger 6 before being .exhausted to atmosphere through pipe 10. Air compressed in the compressor 1 is first heated by turbine exhaust gases in a heat-exchanger 2 and then further heated in tubes 7, 8 before passing to the turbine 4. The plant is controlled by a thermostat 11 in the outlet pipe 14 which controls a valve 12 by-passing the heat-exchanger tubes 7 and 8 and a valve 13 which allows air to enter the upcast air inlet pipe. An increase of temperature will cause the thermostat to open valve 13 and close the valve 12. The thermostat may be placed inside the combustion chamber.9. If desired, the exhaust from the turbine 4 may be cooled in a cooler C and returned to the inlet of the compressor 1. In a modification, the upcast air is preheated in a jacket surrounding the combustion chamber before entering the rotary heatexchanger. In a further modification, upcast air instead of atmospheric air is fed to the compressor. After being heated in the tubes surrounding the combustion chamber, this air is burnt in a second combustion chamber having a second rotary regenerative heat-exchanger transferring heat from its exit to its entrance and then passed to the turbine. In this arrangement, the controlling thermostat may be placed at the outlet of the second combustion chamber.
