Title: Improvements in or relating to television and like systems and apparatus
IPC: H04N9/24
Filed: 1947-08-11
Abstract: 642,954. Automatic control systems for cathode-ray tubes. RAULAND CORPORATION. Aug. 11, 1947, No. 22276. Convention date, Sept. 12, 1946. [Class 38 (iv)] [Also in Group XL (b)] In an arrangement for controlling the accuracy of the scanned pattern on the fluorescent screen of a picture reproducing tube, the pattern is monitored by means comprising a filter array of strip elements which co-operate with control means to provide a signal which is employed to control the scanning means of the tube to compensate for deviations of the scanned pattern from a precise predetermined pattern. The invention is described as applied to a colour television receiving system in which black-andwhite colour selection images reproduced on the fluorescent screen 3 of a cathode-ray tube 1, Fig. 1, are viewed through a colour filter 6 comprising a repeating series of strips selectively transmissive to the component colours employed (e.g. red, green, blue) (Fig. 2). A mar. ginal portion of this filter is masked from direct viewing by means of a screen 7 and photoelectric cells 9, 13, 14, each rendered responsive only to a different one of the component colours employed (by means of filters 10, 15, 16) are positioned so as to respond only to light generated by the marginal filter portion, the scanning electron beam being arranged to excite maximum fluorescence when scanning that part of the fluorescent screen behind the marginal filter portion. The photo-electric cell outputs are selectively combined in a switching and mixing device VII, Fig. 5, which is controlled by a blanking pulse generator IX, the operation being such that the output from each of the photo-electric cell amplifiers, which are blocked in turn for the duration of a single line scan when the colour to which their associated photo-electric cells respond is being reproduced, is arranged to produce two equal pulse signals of opposite polarity one of each of which, depending on the colour scanning sequence. are combined to produce a further signal which is applied to the velocity-modulated vertical scanning generator VIII to control the vertical deflection of the cathode-ray scanning beam. This control then operates to increase or decrease the slope of the vertical scanning sawtooth wave to return the scanning beam to a position in which the correct colour is reproduced, when, due to general inaccuracies in the system, an incorrect colour is reproduced. Details of the devices VII and IX, Fig. 5, are described with reference to Figs. 6 and 8 (not shown). In a modification (Figs. 3 and 4, not shown), a filter screen, the strip elements of which are selective reflective instead of selectively transmissive and which is positioned to receive light from the cathode-ray tube by optical projection, is employed in place of the filter 6 of Fig. 1. With suitable modifications the invention is applicable to black-and-white interlaced or stereoscopic television systems. Specifications 602,053, [Group XL (a)], 642,955, [Group XL (b)], and 642,956 are referred to.

Filed: 1947-08-12
Abstract: 632,747. Electric radiators and cooking- stoves. HANNAH, E. T. G. Aug. 12, 1947, No. 22347. [Class 39(iii)] An electric radiator comprises a hollow casing with movable heating elements 8 arranged such that they may automatically be moved from an opening at the front of the casing to a position beneath an upper hot plate 1 when the opening is closed by a movable shutter 12. The closing of the opening also displaces a pivoted arcuate reflector 18 from a position rearwardly of the heating elements to a position adjacent the opening to increase the heating space within the casing if operating as a cooker. An oven door is at the back of the casing. When the heating elements are below the hot plate, the central elements may be switched off if a low heating temperature is desired. An external terminal box is rotatable with the heating elements to obviate the need for pliable supply wires within the casing.

Abstract: Paper and textile materials comprising cellulosic fibres, e.g regenerated cellulose, alone or in admixture with acetone-soluble cellulose acetate, cellulose triacetate, polyamide, polyester or polyacrylonitrile fibres, may be creaseproofed and rendered dimensionally stable or have their water inhibition reduced by impregnating them with formaldehyde and with at least 0.25 gram per 100 grams of cellulose of magnesium chloride calculated as the hexahydrate in an aqueous solution containing at least 10% by weight of water at a pH of below 5, and then curing them.  The formaldehyde and magnesium chloride are applied as aqueous solutions which may contain other solvents, e.g. methanol and ethanol, providing the solution contains at least 10% by weight of water, and may be applied from the same or separate solutions. The solution preferably contains 0.5-6% by weight of formaldehyde and 0.25-6% by weight of magnesium chloride hexahydrate.  The solution may also contain softening agents, lubricants and water repellents and may be adjusted to the desired pH by the addition of hydrochloric acid or caustic soda. After impregnation the treated material may be dried at 30 DEG -110 DEG C. and cured by heating to 110 DEG -180 DEG C. for from 5 seconds to 30 minutes.  The material may subsequently be treated with ammonia or urea to remove unbound formaldehyde and magnesium chloride. Textile fabrics may subsequently be mercerized or "Sanforized" (Registered Trade Mark).  Specification 930,132 is referred to.

Abstract: 277,317. I. G. Farbenindustrie Akt.- Ges. Sept. 10, 1926, [Convention date]. Cellulose ethers, and processes for making films from.-Water-soluble sulphonated cellulose derivatives are obtained by causing cellulose in the form of an alkali compound or in the presence of an alkaline agent, to react with an aralkylhalide-sulphonic acid. In examples, mercerized cellulose is treated with alcoholic caustic soda solution, and to the mixture is added sodium benzylchloride - para - sulphonate dissolved in alcohol and the mass kneaded at 50-60‹ C.; mercerized cellulose is kneaded with caustic potash solution, the mass then pressed, and mixed with sodium benzylchloride-ortho-sulphonate while heating; mercerized cellulose is soaked with pyridine and then stirred with sodium xylylchloride-sulphonate. The products can be separated by conversion into their calcium or barium salts which are insoluble in water and from which the free acids can be obtained. Because of their incombustibility the products are suitable for impregnating textiles and for the manufacture of fireproof films; when used for impregnating, the fabric is soaked with an aqueous solution of the compound and a salt of a heavy metal, aluminium &c. added in order to precipitate the corresponding salt of the compound on the fibre.

Title: Polymerisation of olefins
IPC: C08F10/00
Filed: 1956-07-23
Abstract: Solid olefin polymers obtained by polymerizing olefins in the presence of an inert liquid and a catalyst comprising an organo-metallic compound, are separated by continuously withdrawing a reaction mixture comprising solid olefin polymer, catalyst and inert liquid from a polymerization zone, passing the reaction mixture to a separating zone and separating the inert liquid mechanically, recycling the inert liquid to the polymerization zone, passing the residual reaction mixture to a vaporizing zone so as to form a seal to prevent entry of gas from the vaporizing zone to the separating zone, treating the mixture with an aqueous acid or alkaline medium to dissolve out the catalyst and vaporizing the residual inert liquid, passing the solid polymer to a washing zone where it is washed with water and then dried.  The preferred catalyst system is aluminium alkyl-titanium chloride and ethylene the polymer.  An apparatus for carrying out the process is described in which the mechanical separation of the inert liquid may be effected in a continuously operated centrifuge or centrifugal sifter, the passage of polymer from separating zone to vaporizing zones by a twin screw, that through the vapourizing zone by paddles or a screw conveyor and the mixture of steam and acid or alkali introduced at several points (preferably from below) into the vaporizing zone.
