Title: Improvements in electric discharge devices
IPC: H01J17/00
Filed: 1956-01-20
Abstract: 790,528. Cold-cathode tubes. GENERAL ELECTRIC CO. Jan. 20, 1956 [Feb. 16, 1955], No. 2019/56. Class 39(1). The dark breakdown voltage rise in a cold cathode discharge tube containing an ionizable gas filling is reduced by adding a small proportion of tritium to the filling. The spark gap tube shown comprises a cylindrical vitreous envelope 1 to which are sealed feathered edged cups 2 of a metal having a coefficient of expansion as near as possible to that of the envelope material. A cylindrical mounting post 3 which serves also as a terminal is welded externally to each cup 2 and has a reduced diameter extension 4 projecting into the interior of the envelope. The end of the extension 4 is bored to accommodate the shank of a rivet-like member 5 which is locked in place by crimping at 6. A button 7 providing the discharge surface is welded to the rivet 5 and may consist of a pressed and sintered mass of tungsten-nickelbarium alloy. The filling is 84 per cent argon and 16 per cent hydrogen at a pressure of 670 mm. of mercury with the addition of 2 millimicrograms of tritium. At a reduced pressure of 200 mm. of mercury an even smaller amount of tritium is required, and a formula is given for calculating the mass of isotope required to provide a given radioactivity. The Specification refers to the prior art of inserting uranium oxide in the form of a suspension or paint on the inside of the envelope of a discharge tube which is dried or baked before sealing. Some 100 milligrams of uranium oxide are necessary to produce the same radioactivity as the small amount of tritium.

Abstract: 1,145,210. Fluid-pressure servomotor systems. BENDIX CORP. Jan. 16, 1967 [Feb. 1, 1966], No. 2213/67. Heading G3P. [Also in Division F1] A fuel supply system for a gas turbine engine includes a metering valve 56 connected to a double-acting servopiston 60 which is controlled by spool valves 66, 118 of which the former is connected to governor 104 whilst the latter is connected with some lost motion to the piston via lever system 126, 144, 150. During steady state operation, the valve 66 maintains engine speed constant by connecting chambers 62, 64 to fluid at high-pressure P S  or lower pressure P R , the latter pressure being determined by a relief valve 86. A velocity feedback to the valve 66 is provided by inter-connected bellows 188, 192, the feedback gain being controlled by needle 210 whilst a further bellows 218 introduces a lag. During acceleration, valve 118 is displaced as a result of lever 126 engaging stop 122 on the valve stem. Fluid at pressure P S  is now supplied to chamber 62 whilst chamber 64 is connected to a pressure P 0  less than P R . The movement of the piston 60 thus comes under the control of valve 118 and the acceleration is controlled by a cam 134 suitably profiled to avoid stall. Deceleration is controlled in a similar manner. The effect of valve 118 is to convert the integrating action of piston 60 to proportional action.

Title: Improvements in or relating to an apparatus or machine for testing the efficiency ofbrakes of automotive vehicles
IPC: G01L5/28
Filed: 1928-01-28
Abstract: 304,485. Jackson, L. Mellersh-, (Brake Synchrometer Co.). Jan. 28, 1928. Dynamometers; systems for testing motor vehicles.-For testing the brakes of a motor vehicle, the wheels are rotated in contact with independently rotatable. rotors moving solely by kinetic energy, and means are provided for measuring the movement of each rotor after the vehicle brakes are applied. The vehicle A is run over ramps 24 on to a platform 21 so that the wheels rest on four rotors or flywheels 32, 34, 45, 46 the surfaces of which protrude above the platform. The rear rotors are carried on aligned independent shafts 29, 31 the inner ends of which carry half pulleys 7, 8. The front rotors are similarly mounted and carry half pulleys 9, 10. An endless belt passes over the pulleys, over a jockey pulley 75 and a pulley 76. The pulley 75 is moved by a lever 81 to tighten the belt which equalizes the speeds of the pulleys and rotors. Each of the shafts 29, 31, 40, 41 is connected by a gear 49, 5 and a flexible shaft 51 to a speedometer on an instrument board 54. Pivotally mounted on a fixed plate is a four-armed spider 56 each arm of which carries a friction disc 57 adapted to engage a disc on the shaft 51. A spring 59 tends to pull the spider so that the friction wheels engage, but a stronger spring 64 acting on a pivoted latch 62 causes the latter to engage a lug 63 and hold the friction wheels 57, 58 out of engagement. The wheels 57 are connected by flexible shafts to tachometers 53 on the instrument board. The latch 62 is connected by a cable with the brake rod 65 operated by the brake lever 66. In use, the frame is adjusted longitudinally to suit the wheel base of the car, the belt 74 is tightened, the cable 6 is connected to the brake mechanism and the engine is started. Cables 104, 105 anchor the vehicle to the support. The speed of each fly-wheel is independently indicated, and when all rotate at a predetermined speed, the lever 81 is operated to loosen the belt, the clutch is thrown out, and the brake applied. The latch 62 is consequently released and the tachometers are set in motion to indicate the travel of each wheel from which readings the brakes may be adjusted and the distance which the vehicle will travel under braking action obtained. The speedometers indicate the speed of the vehicle when braking takes place. Supplementary fly-wheels 36, 37 may be coupled to the fly-wheels 32, 34 in the case of a heavy vehicle. The tachometers may be replaced by a recording device comprising a tape driven at constant speed marked by sparkgap devices timed from each fly-wheel.

Title: Process for the manufacture of colour photographs by using photographic layers having sensitisers in colloidal solution
IPC: G03C7/26
Filed: 1929-01-28
Abstract: 332,893. Heide, E. Wolff-. Jan. 28, 1929. Colour photography; toning. - Photographic emulsions treated with sensitizers, such as pinacyanol, in colloidal solutions whereby a superficial layer is rendered colour sensitive, are exposed through the transparent support and after developing and fixing are treated with a solution such as a uranium intensifier until the exposed gelatine in the superficial layer has been hardened. During exposure a yellow filter may be used or the emulsion may be dyed yellow. If the superficial layer has been sensitized for red, the negative comprises a black and white, silver image formed by the blue-green light in the layer of emulsion nearest the support and a hardened gelatin,e image formed by the red light in the superficial emulsion layer. The negative is treated in a known manner with ferric ammonium oxalate, and hydrochloric acid, washed, and immersed in sodium hyposulphite solution. As a result the red values of the negative assume a transparent blue-green colour. In printing positives from the negative, the latter is immersed in a 5 per cent solution of pinatype blue D which is absorbed by the soft gelatine in the superficial image layer, and is placed in contact with the positive film under water in the dark room. The two films are then pressed together by a roller, the pinatype dye on the superficial negative image being transferred to the positive film, and are afterwards exposed to light, the black and white image on the lower layer of the negative emulsion being photographically impressed on the positive film. After developing and fixing the latter, the emulsion is hardened by a solution of alum or the blue picture is fixed by a mordant. The photographically exposed parts are coloured red by converting the silver image to a silver-uranium compound and dyeing with a basic colour, or the silver bromide picture is converted to silver iodide and then coloured. A slight yellow colour may then be applied to the total picture. A silver bromide paper with a stripping emulsion may be used as positive material. The process is similar when the superficial layer has been sensitized for green, the negative then being dyed with pinatype carmoisin red D before printing. The photographically exposed parts of t.he positive are then toned blue-green with iron ammonium alum, potassium ferricyanide, or a solution containing ferric ammonium sulphate, potassium ferricyanide oxalic acid and sulphuric acid.
