Title: Improvements in or relating to calcium sulphate plasters
IPC: C04B28/14
Filed: 1940-04-08
Abstract: 540,415. Synthetic resin compositions. LEFEBURE, V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 8, 1940, No. 6297. [Class 2 (iii)] [Also in Group V] In the production of calcium sulphate plasters which are mixed with aqueous ureaaldehyde syrups immediately prior to use, setting of the plaster is accelerated by incorporating in the calcium sulphate not more than 2 per cent. of a salt which dissolves in water to give an acid reaction thus causing hardening of the resin. Salts specified are potassium and sodium hydrogen sulphates and alum. Ammonium hydrogen sulphate and ammonium chloride may also be used but have the disadvantage that ammonia is evolved by re-action with the lime. Retarders may also be added to prevent too rapid setting, e.g. fused meta- and pyro-phosphates as described in Specification 458,437, [Group V], or keratinous refuse and dry hydrated lime (up to 0.1 per cent.). A plaster is prepared by mixing 10 cwts. calcium sulphate hemihydrate plaster with 6 lbs. organic scutch retarder and 6.7 lbs. powdered potassium hydrogen sulphate and then adding a further 10 cwts, plaster with further mixing. For use 100 parts of the plaster are mixed with 12¢ parts urea-formaldehyde syrup containing 75.5 per cent. resin and 47¢ parts water. The mixture may be used for the core of plaster boards or as an adhesive for bonding layers of plaster board as described in Specifications 540,326, [Group VIII], and 491,882, or as a camouflage applied to hessian or canvas backings.

Abstract: 234,920. Thomson, C. H., Cummiskey, J., Miller, C. J., and Jones, A. L. March 12, 1924. Safety cut-off valves.- A valve device adapted to be opened manually and maintained open by the fluid flow has the valve member loosely connected to an actuating disc working in a cylinder with a central restricted zone. In the form shown in the Figure the conical valve member 6 controls a side inlet port 8 and is mounted between stops 11, 12 on a spindle 9 connected to a floating disc 13. The stop 11 is of appreciable weight so that the valve member is given a slight hammer blow in closing. The sides of the stops adjacent the valve member may have radial grooves. The disc 13 which may be slightly dished works in a cylinder 1, of which the part a, b is reduced in diameter to allow only a very slight clearance, while the upper and lower parts are flared, the upper one to permit an increased flow of gas, the lower one to permit sudden closing on cessation of the gas supply. The upward movement of the disc is limited by a notched flange on the part 2 of the casing. The valve is opened initially by means of a spring pressed push rod 15. Vertical grooves may replace the flared points. A modification is described in which both inlet and outlet connections are arranged at the side of the casing. According to one Provisional Specification two or more actuating discs may be secured to the spindle and the valve .spindle may be guided by perforated discs arranged above and below the valve or the spindle may have a tail piece engaging a socket in the end of the push rod 15. The sides of the valve member may be recessed. The actuating disc may act through a lever or toggle mechanism to operate a tapered plug, flap, disc, ball, louvre or mushroom valve or a rotating cock. According to the other Provisional Specification, the valve may be fixed to the spindle, the lower stop may be, ball or pear shaped, and the lower end of the valve member may be tapered at a more obtuse angle than the seat.

Convention date, Dec. 9, 1939. Addition to 543,485. [Class 40 (iii)] ] Relates to television receivers comprising a cathode-ray tube 1, Fig. 1, containing a layer 20 locally deformed into lenses by the action of the cathode ray as described and claimed in the parent Specification to modulate a light beam from a separate light source 10 to reproduce the image on a screen 18. According to the invention, the light stream from the separate light source 10 is controlled in accordance with the average picture brightness and an equalization is simultaneously and automatically controlled by varying the intensity of the television signal transmitted to the cathode ray tube. This produces a satisfactory grading of image brightness on the screen. As shown in Fig. 1, the average picture brightness is determined by an averaging device in the signal amplifier 43, and this averaging device controls the signal intensity transmitted to the cathode-ray tube 1 and also controls, by means of an electromagnet 41, a shutter 40 in the light stream from the light source 10. In a modification, the average picture brightness of a picture film is determined photo-electrically and the output of the photo-electric device is used to control the light stream shutter and the amplifier of the signal transmitted to the cathoderay tube.
