Title: Improvements in or relating to mechanically propelled dumpers
IPC: B60P1/24
Filed: 1955-12-30
Abstract: 808,216. Tipping trucks. LINER CONCRETE MACHINERY CO. Ltd., HODGSON, T. R., and SHELTON, J. L. Jan. 28, 1957 [Dec. 30, 1955], No. 37400/55. Class 108(1) A dumper has a skip 10 which in addition to having a full load position and a dumping position also has at least one intermediate (i.e. loading) position in which its loading end is somewhat lower than that when it is in said full load position whereby said loading end can easily be run under the discharge opening of a concrete or like mixing drum or other container so as to receive a load therefrom, the skip 10 having upper and lower cross-bars or members 15, 18. Adapted to be engaged selectively by a releasable hook or hooks 12 or the like so as to hold the skip on either the full load or the loading position. Cross-bar 15 is secured to the skip frame by brackets 16 and cross-bar 18 is suspended by links 19 from bross-bar 15. The hooks 12 are rigidly mounted on a cross-rod 13 carried by fixed brackets 14, the rod 13 being movable by a hand lever or pedal when it is desired to disengage the hooks and cross-bars to release the skip.

Title: Improvements in or relating to cathode ray tube circuits
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N3/20
Filed: 1957-12-02
Abstract: 864,933. Cathode-ray tube circuits. BUSH & RANK ClNTEL Ltd. Dec. 2, 1958 [Dec. 2, 1957], No. 37444/57. Class 40(7) Relates to circuits for preventing the production of a focused beam in a cathode-ray tube in the absence of both or one of two scanning generator outputs. The frame time-base potential at terminal 1 is amplified by valve 3 and fed to voltage-doubling peak-rectifier 12... 15. The rectified signal is fed to triode 17 together with the line time-base signal from terminal 18. The cathode of triode 17 is so biased, from divider 21 . . . 24, that a relay 20, which controls the production and/or focus of the C.R.T. beam, and which is in the anode circuit of the triode 17, is operated only when both inputs are simultaneously present. A small inverse current is passed through relay 20 from resistor 31 to render the circuit more sensitive to changes in the operating signals and to reduce its release time. Upon first energising the circuit, positive surges at the anode of valve 3 are by-passed from the rectifiers 12, 13 by a rectifier 25 which, after an interval, becomes non-conducting due to the application of a positive potential to its cathode from voltage-divider 27, 28 which includes a time-constant condenser 26. Such surges are also reduced by the provision of a time-constant cathode biasing circuit 6, 7 and screen grid supply circuit 29, 30. The gain of valve 3 is stabilized by a feedback circuit 9, 10, 11.

[Also in Divisions B2 and G2] A composite film comprising two hydrophobic layers is produced by casting on a casting surface a first solution of a cellulose ester in a solvent or solvent mixture with a boiling point or with boiling points below 100‹ C. and thereafter casting a second solution of a cellulose ester in a solvent or solvent mixture with a boiling point or boiling points below 100‹ C. to form a layer on the layer formed from the first solution while that layer remains on said casting surface and still contains a substantial proportion of solvent, one of the said solutions having a black pigment dispersed therein and the other a white pigment dispersed therein. The black pigment may be carbon black whilst the white pigment may be titanium dioxide, barium sulphate, zinc white or lead white. The carbon black may be present in a concentration of 1-5% by weight with respect to the total weight of solid material in such layer, whilst the concentration of the white pigment may be 10-55% by weight of the solid material.

Title: Decarburizing high-carbon ferrochromium
IPC: C21D3/04
Filed: 1956-12-17
Abstract: Low carbon ferrochromium is produced by heating pellets formed of high carbon ferrochromium and a gangue containing oxidant in sufficient amount to give an excess of oxygen over that required for the carbon-oxygen reaction, in a furnace under reduced pressure and at a temperature high enough to permit the carbon-oxygen reaction but below the melting point of the pellets, increasing the temperature in steps until the carbon-oxygen reaction is complete and cooling the low carbon ferrochromium produced.  The gangue containing oxidant may be iron ore, chromium ore, manganese ore, or oxidized high carbon ferrochromium.  The pellets may be placed in a vacuum furnace evacuated to 2500 microns mercury, heated to 1250 DEG C., the vacuum increased to 75 microns, and, when the carbon reaches 2.5 per cent, the temperature raised progressively to 1375 DEG C. at which it may be maintained until the carbon is reduced to 0.01 per cent.  The temperature may finally be increased to melt the gangue and allow it to form a seal on the surface of the pellets.

Abstract: 1436208 Producing glass films F M HENNEQUIN 14 Aug 1973 [21 Aug 1972] 38453/73 Heading C1M A glass film is produced by providing the material of which the film is to be formed, or constituents of the material, in the vapour state under a vacuum, condensing the vapour to the solid state on the surface of a liquid (e.g. mercury), and removing the condensed film from the liquid. The film may be formed by deposition of a single material, by simultaneous deposition of different constituents, or by successive deposition of constituents to form a stratified film. The liquid is preferably at ambient temperature, and preferably does not react with or dissolve the film. The liquid 26 (Fig. 1) may be provided in enclosure 10, film 14 formed being continuously removed through opening 12 on to reel 16 (opening 12 may be lined with, e.g. rubber to reduce ingress of air). The enclosure 10 may be provided with three cells 18, 20, 22, each of which contains a different vapour. Materials to be vaporized are charged into gas-heated troughs 24. The liquid 26 may be prevented from flowing over the film 14 by applying an adhesive beading 28 to the edges of the film (Fig. 2), or by folding upwards the edges of the film (Fig. 3, not shown).
