Patent GB-455267-A (GB)
Title: Mains supply apparatus for television tubes
IPC: H04N3/18
Filed: 1935-02-11
Abstract: 455,267. Control systems for discharge tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Feb. 11, 1935, No. 4283. Convention date, May 19, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 13, 1935.] [Class 38 (iv)] The A.C. supply to cathode-ray tubes used for television apparatus is smoothed to such an extent that the residual ripple potentials in both the grid and cathode circuits are equal as regards amount and phase. A transformer 1 is connected to the anode 20 and cathode 8 of the cathode ray tube through a rectifier 4, smoothing means consisting of condensers 5, 7 and resistance 6 being provided. The control grid 9 receives its bias potential from an adjustable tapping of the resistance 6. The image currents are supplied to the grid 9 from the receiver 12 through condenser 11. To provide ripple elimination of equal extent for the grid and cathode circuits, the circuits form a bridge, one branch consisting of the resistance 6 and condenser 7 while the other branch consists of resistance 10 and condenser 11, the grid and cathode being connected to opposite corners. By adjusting resistance 10 or condenser 11 a point may be found at which grid and cathode humming potential are co-phasal and the image is clear. To prevent fog of the image, a condenser 24 and resistance 25 are introduced so as to transmit the full humming potential of the supply to the point 26 thus making it necessary for the resistance 10 and condenser 11 in the grid circuit to possess a greater time constant than the cathode circuit.

Title: Improvements in or relating to oil cracking stills
Filed: 1925-02-16
Abstract: 240,355. Jackson, W. J. Mellersh-, (Sinclair Refining Co.). Feb. 16, 1925. Hydrocarbons, cracking. - In an oil-cracking still, in which the oil is passed through externally heated tubes 2, combustion is effected with preheated air and the necessary tempering of the hot gases obtained by admixture subsequent to combustion, of relatively cool waste gases. The air, preheated in a tubular heater 21 arranged in the waste gas flue 19, is supplied at 25 and the returned waste gases at 30. The flow of air is induced by the fuel jet from the burner 11 and that of the waste gases by steam injectors 28 arranged in pipes 27 which are disposed outside the furnace and deliver to a chamber 29 communicating with the inlet 30. A modification is described in which the vertical oil tubes 2 are replaced by three series of horizontal tubes connected by curved end-pieces so as to form continuous zig-zag passages.

Abstract: 783,796. Clips. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Feb. 14, 1956 [Feb. 14, 1955], No. 4371/55. Class 44 [Also in Group XXXVI] A clip for supporting a conductor wire (not shown) from an overhead cable 1 comprises a pair of clamping plates 3, 4 and a locking bar 5, the clamping plates 3, 4 being formed at one end with a pair of jaws 10, 11 for grippinig the wire or the cable 1, the outer faces of the clamping plates having inclined surfaces converging from the jaws to a point from which they continue to converge or run approximately parallel for a short distance, then sharply approach one another to form the risers 6, 7 of a pair of steps 8, 9 and finally run approximately parallel, the locking bar passing through apertures 14 located at least partly in the steps 8, 9 and having a laterally projecting lug 15, 16 at each end of the bar lying outside the clamping plates, and the locking bar 5 being rotatable from a locking position (Figs. 1, 2) in which the lugs are directed towards the jaws and engage the inclined surfaces so as to press the jaws firmly into contact with the wire or cable, into a second position in which the lugs are clear of or approximately at right angles to the slope of the inclined surfaces and lie over the steps thus partly releasing the jaws, and from the second position into a full release position in which the lugs are clear of the steps. The lower extremities of the plates 3, 4 are bifurcated, one prong of each strip (e.g. 17 in Fig. 2) being turned inwardly to bear against the straight prong of the other strip. Circular holes 12, 13 in the two clamping plates serve for the passage of a link, hook or bolt for connecting the clip to the conductor wire (not shown). In a modification (Fig. 3, not shown) the plates converge steadily from the jaws (10. 11) to the risers or joggled portions (6, 7), and the prongs at the lower extremities of the plates are joggled instead of being turned in. Fig. 4 (not shown) illustrates a further modified form of clip having jaws shaped to fit in side grooves in the suspended conductor wire.
