Title: Method of Fabricating a Colour Cathode Ray Tube Screen.
IPC: H01J9/227
Filed: 1967-08-03
Abstract: 1,183,849. Luminescent screens. SYLVANIA ELECTRIC PRODUCTS Inc. 3 Aug., 1967 [8 Aug., 1966], No. 35779/67. Heading H1D. A method of fabricating a c.r.t. screen with sets of discrete elements of at least two differently coloured light emitting phosphors (e.g. a colour T.V. tube with red, green and blue phosphors) comprises cleaning the faceplate, which may be concave, and providing on the plate a uniform layer of tacky material, e.g. polyvinyl alcohol with ammonium or potassium bichromate, sensitive to electrons and optical radiation for example (u.v. sensitivity is instanced) under conditions, e.g. a saturated atmosphere, such that the material remains tacky for a prescribed time. The faceplate is positioned at a phosphor receiving station with an environment of relative humidity 40 to 50% and temperature 70‹ to 80‹ F., the plate being surrounded with a phosphor cloud confining tub with an aperture to receive a phosphor dispensing gun. Dry phosphor particles are mixed with substantially contaminant free air, e.g. containing no impurities of size larger than 7 microns preferably 3 microns and of temperature 40‹ to 50‹ C. and relative humidity less than 5%, and dispensed through the gun preferably normal to the longitudinal axis of the screen. The screen is rotated at preferably one to six revolutions per minute. The radiation exposure sensitive material and the phosphor are preferably sprayed in bursts, the former upwardly to the support. The cut-off of the rotation and bursts may be effected automatically, e.g. by a p.c. cell and light source above and below the face plate respectively. Elimination of chloride contamination is mentioned. Reference is made to a general controlled environment of pressure slightly greater than atmospheric.

Title: Improvements in plants for preventing and fighting fire, by means of inert gases
IPC: A62C99/00
Filed: 1932-12-17
Abstract: 416,563. Extinguishing and preventing fires. FAURE, H., 3, Rue des Saints- Peres, Paris. Dec. 17, 1932, No. 35819. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 20, 1933]. [Class 47 (ii).] Relates to systems for storing and moving combustible materials under an inert atmosphere, and consists in washing the exhaust gasses from an explosion engine, and then compressing them, by a compressor driven by the engine, to the maximum degree permitted by the capacity of the engine. The gases can then be stored in reservoirs of small capacity, or may be passed direct, by way of a reducing valve, into the tanks, &c., to be protected. The exhaust gases pass from the engine 14 to a washer 16 and thenca to the compressor 15. This forces them through a non-return valve 25 and water separator 26 into the reservoir 17. The valve 25 is spring-loaded to allow passage of gases only at a certain pressure, say 35 kgms. per sq. cm. The compressor is preferably of such dimensions and working speed that a pressure about half of atmospheric exists at the suction port from the engine exhaust. The reservoir 17 discharges to a header 28 through a pressurereducing device 27 of such character that gases are admitted automatically to the header if the pressure therein falls below a predetermined point. The header 28 is connected to a storage tank 1 by a pipe 21 and to a relay tank 2 by a pipe 22, three-way cocks 30, 31 being interposed in the pipes 21, 22. In the storage system shown, Fig. 2, the underground storage tank 1 is connected by a delivery pipe 13 to a distributing head 4. The relay tank 2 can be connected, by pipes 10, 11 and suitable valves, either to the pipe 13 or to a receiving head 12. Normally, the tank is filled with gasoline, &c., by gravity, and the gasoline is then forced into the tank 1 by inert gas. For the latter operation, an auxiliary compressor 19 of low capacity withdraws gases from the tank 1 by the pipe 23, and forces them into the tank 2 by way of the pipe 24, the cocks 30, 31 having been set suitably. If there is insufficient gas in the tank 1, more is supplied from the reservoir 17 by way of the valve 27. Preferably, pressureoperated devices are provided on the suction and delivery sides of the compressor 19, for stopping the compressor if the pressure falls below or rises above a predetermined point. Cocks 3 and 7 are arranged in the delivery pipes from the tanks 1 and 2. These cocks are controlled by pipe lines 5, 8, 9 which run beside the delivery pipes 13, 10, 11 and are charged with gas at moderate pressure from an auxiliary reservoir. If a delivery pipe is ruptured, the corresponding gaspipe will probably be ruptured also, and the fall in pressure therein is utilized to cause closure of the corresponding valve 3 or 7, thereby preventing leakage of the gasoline. The gas pipes may include ports closed by readily-fusible metal. An emergency cock 32 allows gas to be passed direct from the compressor 15 into the tanks 1, 2.

Title: Oxygen dispensing
IPC: B64D13/04
Filed: 1959-10-26
Abstract: 866,029. Respiratory equipment. AIR REDUCTION CO. Inc. Oct. 26, 1959 [Oct. 27, 1958; Sept. 30, 1959], No. 36267/59. Class 81 (2). An oxygen supply system for use under conditions of negligible gravity, when oxygen in liquid form could not be used owing to problems arising from the absence of gravity, comprises a thermally insulated container 10 connected to a reducing valve 30. The conduit is also connected to a pressure-sensitive switch 32, which causes current to flow through a heating element 135 when the pressure falls below a predetermined level. Liquid oxygen is introduced into the container 10, at atmospheric pressure, to fill it partially only, and the container is sealed, either by screwing on the cap 18 or by applying a closure member 22 to a filling tube 21. When the equipment is required for use, the electric current is switched on and the container is heated until the whole of the oxygen is converted into the gaseous form, it then being at a pressure of between 735 and 1000 lbs./sq. inch and at a temperature between -175‹ F. and -300‹ F. Thereafter, as the gas is used, the pressure is maintained by gradually raising its temperature, under the control of the pressure-sensitive switch 32 and heater 135. The gas issuing from the reducing valve 30 is passed through a heater 26 prior to use in a mask. A suitable form of pressure-sensitive switch 32 is described with reference to Fig. 2, in which a Bourdon type tube 110 actuates a contact blade 116 through a push rod 115, so that it engages a fixed contact 118. When the tube 110 extends, under rising pressure, the blade 116 is allowed to move away from the contact 118, to break the circuit. The pressure at which this occurs is determined by adjusting the position of the whole assembly 126 by means of a screw 130. The gradual rise in temperature, as the gas is used, for maintaining a steady pressure, is used as an indication of the amount of gas remaining and is measured by a thermocouple 18a, Fig. 1, in the container.
