Abstract: 195,764. Evans, D. A., and Hodgson, H. Jan. 9, 1922. Motors, cooling.-To prevent condensation of moisture within an enclosed electric motor particularly when working submerged in water, air is circulated in a closed circuit within the water-tight casing, and heat insulation is arranged between the field-magnet carcase and the casing so that there is no direct cooling of the magnet &c. from the outside. The field magnet b, Fig. 1, is surrounded by a lagging f of asbestos &c., and an annular space, r is provided between the magnet and the outer casing q. Heat insulation g may also be placed between the field frame and the end covers h, j. A fan s draws in air through perforations in the cover h into passages w, x. A deflector z directs air on to the magnet windings e, and a fan y drives the air through apertures v into the space r where cooling of the air by direct contact with the outside casing takes place. The stuffing-box n prevents entry of water into the motor. Perforated containers filled with hygroscopic material may be placed inside the end cover t to absorb moisture. In a modification, Fig. 2, the end cover h and fan s are dispensed with. Entry of water is prevented by a stuffing-box consisting of a casing 1 having its end walls fitted with white-metal or other packing-rings 2. Two flanged bronze sleeves 3 are kept in tight contact with the packing-rings by a spring 4. According to the Provisional Specification, one of these flanged rings may be fixed.

Abstract: 504,056. Engine valve-gear. WOODARD, W. E. Jan. 11, 1938, No. 889. Convention date, Jan. 21, 1937. [Class 122 (ii)] Comprises a locomotive, duplex valve gear wherein the motion of separate admission and exhaust poppet valves are obtained from oscillating cams operated by combination levers operated by the dual action of the crossheads of the two cylinders on opposite sides of the engine. The movement of the cross-head of a cylinder gives the lap and lead motion, and the movement of the other cross-head the travel motion. The method of operating the combination levers is the same as that described in Specification 487,686. In the present construction, each combination lever therein described is replaced by two combination levers of different length for the admission and exhaust valves respectively. In the engine shown the cranks are at 90‹. Steam is supplied at 41, Fig. 2, and exhausts at 43. Cam boxes 45 are mounted on the valve-chests and embody intake cams 46, Fig. 8, and exhaust cams 47, Fig. 9, operated by shafts 48, 49 respectively. The cams operate the valves through bellcranks on shafts 53, 60. The starting-points of the inlet and exhaust cam surfaces 65, 69 are 26¢ and 2¢‹ respectively from the centreline d .. d. Figs. 10, 11. The bulk of the gear is contained in a removable box mounted on a base-plate 71. The cross-heads 37 are connected by links 72 to rock-shafts 76 coupled to shafts 76R, 76L in the casing, which carry yokes 83R, 83L, Fig. 3, pivoted in a central bracket 85a. Diagonal cross-rods 86, 87 operate links- 88L, 88R. The reversing-shaft 80 carries arms 97R, 97L which raise or lower radius rods to modify the valve-gear setting. The rods are pivoted at 102R, 102L, Fig. 7, to combining-levers pivoted at 103R, 103L to the yokes 83R, 83L. ' The right-hand combination lever which combines the motion of yoke 83R and link 88R operated by the two crossheads respectively, comprise arms 104R, 105R for the inlet and exhaust valves respectively of the right-hand cylinder. The exhaust arm 105R is the shorter. Similarly levers 104L, 105L serve the left-hand cylinder. The inlet rods 106R, 106L connect the levers 104R, 104L to the rock-shafts 110R, 110L. Similarly the exhaust rods 112R, 112L oscillate shafts 116R, 116L. The shafts 110R, 110L, 116R, 116L are connected by other cross-shafts, cranks, and connecting-rods to the shafts 48, 49, Fig. 2. Cycles of operation with cut-offs of 60 per cent and 15 per cent respectively are described and compared with those given by a gear of the kind described in Specification 487,686.

Abstract: 653,054. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Jan. 13, 1948, No. 971. Convention date, Jan. 13, 1947. [Class 39 (i)] A television transmitting tube has a target electrode comprising a photo-electrically emissive mosaic layer on one side of a transparent insulating plate and on the other side of fluorescent layer scanned by a cathode-ray beam. A lens O projects on to a transparent photo-cathode P, and the electron image is focused by anode A and coil B on to a photosensitive mosaic C which is mounted on a thin mica plate M, on the other side of which is a very thin layer of platinum or tungsten connected to the output impedance Z, and a layer F of short afterglow fluorescent material. The latter is scanned by a high velocity electron beam from gun D. The tube may be divided into two parts in the plane of the mica permitting separate treatment of the cathodes. The fluorescent layer itself may be conducting avoiding the use of a signal layer. The Specification as open to inspection under Sect. 91 also comprises replacing the mica by a semi-conducting material, e.g. thin glass containing traces of metal oxide. No fluorescent layer is used, the first mosaic is not necessarily photo-sensitive but must have strong secondary emission, and the signal plate is a very fine mesh grid placed close to the semi-conducting layer. This subject-matter does not appear in the Specification as accepted.
