Abstract: 749,058. Television pick-up tubes. CATHODEON, Ltd. Dec. 22, 1953 [Dec. 24, 1952], No. 32749/52. Class 39 (1). A television pick-up tube 1 has the final anode 7 of the electron gun 6 provided with attached sleeves 12 mounted to slide freely upon rods 13 arranged longitudinally in the tube and fixed to a ring 14 forming part of the gun assembly whereby the anode 7 can be retracted towards the gun end of the tube, Fig. 1, leaving sufficient space for the entry of an evaporating means 9, for photo-conductive or other light-sensitive material, and heater 10 through an aperture 11 in the tube envelope near the transparent signal plate 2, the anode 7 being moved back, after the aperture 11 has been sealed off and evaporation of the light-sensitive material on to the plate 2 has taken place, along the rods 13 to its normal position, Fig. 2. After evaporation and prior to the anode 7 being moved back to normal position the evaporating means 9, 10 is removed and the tube re-sealed and evacuated. The anode 7 is moved back to normal position by magnetic attraction, by sliding a magnet along the outside of the tube or by tapping the tube with target downwards. The anode 7 is held in its normal position by spring catches 16 supported on a member 17 in the gun assembly and engaging in diametrically opposed apertures 15 in the anode 7. The anode 7 has a mesh screen 8 and is provided with a collar 19 slidably engaging over a tubular portion 20 of the gun assembly. The sleeves 12 and rods 13 form an electrical connection between the anode 7 and the gun assembly and this is enhanced by pig-tail connections 18 between the anode 7 and a terminal or terminals within the tube. The photo-conductive material 3 evaporated on to the transparent signal plate 2 can be oxides, such as cuprous oxide, selenium, sulphur or suitable sulphides or selenides. The signal plate 2 is protected by a glass face 4 and between the tube envelope and the glass face 4 there is provided a metal ring, of, for example, material known under the Registered Trade Mark " Kovar," which is in contact with the signal plate 2 to form the output terminal.

Abstract: 537,824. Radial cylinder engines. MAWEN MOTOR CORPORATION. Dec. 22, 1939, No. 32767. Convention date, Dec. 29, 1938. [Class 7 (ii)] The cylinder block 20 rotates relatively to the crankshaft within a stationary ring 12 containing inlet and exhaust ports and ignition devices ; the crankshaft is geared to the cylinder block. and to the propeller shaft 44 through epicyclic gearing adjustable to vary the phase relation of the pistons in the cylinders and consequently the time of ignition. Toothed wheels 66, 83 are secured to the crank-shaft. The wheel 66 is connected to the cylinder block through planetary gearing including the gears 72, 74 and the carrier 68. A toothed ring within the fixed casing member 76 surrounds and engages the pinion 78. The gear 83 drives the shaft 44 through planet pinions 84 and their carrier 88 which is integral with the shaft. The internally toothed sleeve 80 engaging both the pinions 72, 84 is adjustable in response to the oil-pressure set up by the engine. A cylinder 98 interposed between projections on the hub of the sleeve 80 and the framing receives the oil, and adjusts the phasing and timing against spring-pressure, a check-valve serving to prevent abrupt action by the spring. Ignition is by glow-plug energized continuously, but exposed momentarily by the passage of the cylinder head port over the corresponding opening in the ring 12.

Abstract: 330,218. Smith, W., Thomas, J., and Scottish Dyes, Ltd. Nov. 28, 1928. Indanthrone derivatives. - Halogen atoms in the alpha-positions of halogenated indanthrones are replaced by amino or phenoxy groups, or by sub. stituted amino or phenoxy groups, by treating indanthrones having halogen atoms in the aposition with ammonia, or with primary or secondary amines, or with phenols. The treatment with phenols is carried out in the presence of copper or a copper compound as a catalyst and in the presence of acid absorbing agents, and these substances may also be used in the treatment with amines. The reactions may also be carried out in the presence or absence of diluents. The parent materials may contain further halogen atoms in the 3 : 3<1>-positions.
