Title: Improvements in or relating to methods of manufacturing display screens of cathode-ray tubes
IPC: H01J29/18
Filed: 1963-01-09
Abstract: 958,102. Colour television tube screens. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 9, 1963 [Jan. 12, 1962], No. 1038/63. Heading H1D. In manufacturing a multi-colour, cathode-ray tube display screen, the last luminescent material to be applied is mixed with a photosensitive binder and is spread on the screen support over the previously applied discrete luminescent areas. The binder is then exposed to the influence of a hardening radiation, both on its free surface at those areas at which the discrete areas of the last luminescent material are desired, and also through the support. The two irradiations are such that the binder is not hardened at the previouslyapplied luminescent areas, this unexposed binder being subsequently removed. Irradiation through the support causes the binder to be hardened over substantially the whole of its contact area with the support, whereby the last applied luminescent material fills the whole surface area of the support between the previously-applied discrete luminescent areas, and has a layer thickness which is greater in discrete areas, due to the irradiation on its free surface. The last-applied luminescent material may be a red-luminescing zinccadmium sulphide activated with silver. The luminescent materials are then coated with a reflecting, electron-permeable, metallic layer. Specifications 915,845 and 916,832 are referred to

Title: Process for the production of anhydrous fluorides
IPC: C01G43/06
Filed: 1956-01-13
Abstract: <PICT:0798489/III/1> Anhydrous fluorides of metals of the actinide and lauthanide groups, e.g. tri- or tetrafluorides of uranium or thorium are produced by treating the metal oxide in counterflow with hydrofluoric acid at elevated temperatures, in which the oxide is pre-heated to a temperature above the dew-point of hydrofluoric acid and water produced, and below the decomposition temperature of the hydrated fluoride.  Preferably an inert gas is present to maintain superatmospheric pressure.  Preferably the temperature increases from 150 DEG  to 250 DEG  C. at the inlet of an elongated reactor to 350 DEG  to 550 DEG  C. at the outlet, whereby the oxide is first converted to a hydrated fluoride which is then converted by anhydrous hydrogen fluoride to the metal fluoride.  In a suitable apparatus, a container 2 for uranium dioxide is heated by an element 4 to a temperature of 150 DEG  C., and is connected by a vibrator or feed screw 6 to a reaction vessel 14 heated by a furnace 15 to about 500 DEG  C.  The vessel 14 is lined with an aluminium or magnesium tube having a wall thickness of 2 to 5 mm., and is rotated.  Means 16 are provided at each end to make the vessel gas-tight.  Hydrogen fluoride diluted with about 10 per cent by volume of hydrogen passes through a pre-heater 22 maintained at 300 DEG  C. and flows through the reaction tube 14 in countercurrent with the thin layer of uranium oxide.  Excess hydrogen fluoride, water vapour, and hydrogen passes through the charge of uranium oxide in vessel 2 to a washing tower 24 supplied with a spray of caustic soda solution.  The residual gas consisting of hydrogen passes through a water trap 26, adjusted to maintain a pressure of 50 mm. water column in the washing tower. Alternatively the hydrogen may be admitted at the charging inlet.  In operation, uranium dioxide is fed at a rate of about 2 kg. per hour through the reaction chamber 14 which is slightly inclined, and its rotation is adjusted to this rate of flow.  The uranium tetrafluoride produced falls into a vessel 20, and contains less than 0.5 per cent each of uranyl fluoride and uranium dioxide.  The uranium oxide used may be obtained by heating uranium oxalate, or by treating a uranium salt with an acid amide as described in Specification 785,997.

Filed: 1956-01-18
Abstract: 778,522. Brake cylinders. BOSCH GES., R. Jan. 18, 1956 [Jan. 22, 1955], No. 1669/56. Class 103 (1). The piston 5 of a brake cylinder has throttle bores 19 therein which are adapted to be closed by engagement with seals 21 on a flanged ring 17 welded to a guide tube 7 when pressure applied in chamber 4 moves the piston 5 to apply the brakes through a piston rod 14. On release of the brake pressure, the piston 5 moves back, together with ring 17 and guide tube 7 until the pressure in chamber 4 is in excess of that in chamber 11 by about 0.3 atmosphere whereupon the spring 18 separates piston 5 and ring 17 to allow equalisation of pressures on each side of the piston through the apertures. By using this type of construction, in combination with a non-return valve, not shown, at the non-pressure end of the cylinder, it is possible to prevent the entry of any air which may carry with it solid or liquid matter, during the return stroke of the piston. An embodiment for a longer type of brake cylinder is also described.
