Abstract: 1,182,249. p-Xylene. IMPERIAL CHEMICAL INDUSTRIES Ltd. 18 July, 1967 [4 Aug., 1966], No. 34979/66. Heading B1G. [Also in Division C5] A liquid mixture containing p-xylene together with one or more of o- and m-xylene and ethyl benzene is cooled, to effect crystallization of the p-xylene, by dissolving carbon dioxide gas in the liquid under pressure and then evaporating at least a portion of the gas. The mixture may contain 12-25% of p-xylene. The gas may be absorbed at 10-40 atmos. and 25-45‹C. The gas may be compressed in several stages and contacted with the liquid at one or more of the intermediate pressures as well as at the final pressure. The gas may also be evaporated in stages matched with the compression stages, the gas being passed from an evaporation stage to the corresponding compression stage. Before cooling by evaporation, the liquid containing absorbed gas may be cooled to -30‹C by indirect heat exchange with melted crystal product. The thereby further heated product may melt further crystal product by direct contact therewith. The crystal product may be separated from mother liquor by means of a thickener and centrifugal filter or a pulsed reflux column.

Title: Activation process for electron emitters
IPC: H01J9/04
Filed: 1933-12-14
Abstract: 430,170. Thermionic cathodes. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Prescott, C. H. ; 32, Hollywood Avenue, East Orange, New Jersey, U.S.A.) Dec. 14, 1933, No. 35203. Convention date, June 30. Drawings to Specification. [Class 39 (i)] A cathode containing barium and strontium oxides is activated by heating it in the presence of a hydrocarbon gas of the paraffin series, such as methane. The cathode is then heated in a vacuum to stabilize its activity. In an example, a thermionic cathode consisting of a core of nickel or platinum is coated with barium and strontium carbonates in a suitable fluid suspension medium, with or without a binding material, such as an alkaline earth nitrate. The prepared cathode is sealed into an envelope connected to a suitable evacuating system, and the envelope is evacuated. The envelope is heated nearly to softening point in a baking oven, and the cathode is heated to a glowing temperature by a suitable battery to out-gas it and to convert the carbonates into oxides. The plate and grid may also be heated by highfrequency currents or by electron bombardment in a known manner. When the system is thoroughly out-gassed, a hydrocarbon, such as methane, is introduced at a pressure of about À01 mm. and the cathode is caused to glow for a short time at approximately 50 per cent above its normal operating current. The methane reacts with the barium and strontium oxides, either directly or after decomposition into hydrogen and carbon, producing free metal. The envelope is then re-evacuated, subjected to a further outgassing and stabilizing treatment and sealed off. The process may also be applied to coatings containing a compound of a finely divided metal of the eighth group, such as nickel, dispersed throughout the barium and strontium carbonates, usually in the form of oxides the reduction of which is completed by the hydrocarbon in the above-named process. Specification 430,169 is referred to.

Abstract: 211,643. Case, C. Z. Dec. 28. 1922, Trays, dishes, and containers combined with plate holders and for roll-films.-A phothgraphic camera, dark-slide, or the like in which a plate or film is held for exposure is provided witii an absorbent pad or roller impregnated with a desensitizing agent, and with means for bring- ing the roller into contact with the exposed surface of the plate or film after exposure, but before removal from the holder. For use with a plate or flat film B', Fig. 2, held in a darkslide B, the roller C is slidably mounted in guides A' in the side walls of the camera A. The ends of the roller C are carried by two laterally disposed tapes D the upper ends of which are secured to a spring-loaded roller E, which tends to keep the roller C in the upper position out of contact with the plate B<1>, and the lower ends to a roller F which can be rotated to draw the roller C down into contact by pulling a string G. In a roll-film camera, the absorbent roller H, Figs. 3 and 4, is mounted, between the exposure opening and the film reception reel J, on links L connected by friction clutches N or the like to the reel J, so that on turning the winding handle M the absorbent roller H is swung from the inoperative position into contact with the film against the tension of springs N'. The absorbent roller, which may be in the form of a rotary brush, may be mounted in a light-tight and water-tight compartment having a door which is opened to allow the roller to project therefrom by means operated by the winding mechanism. The compartment may have a removable end-wall allowing recharging of the roller when the camera is loaded. The film backing-paper is waterproofed with paraffin wax or the like to prevent the film adhering to it after contact with the roller. Glycerine or like hygroscopic liquid may be added to the desensitizing agent on the roller.

Abstract: 994,813. Cigarette-making machines. K. KÍRBER. Sept. 19, 1962, No. 35619/62. Heading A2C. A device for varying the feed path of cigarettes conveyed transversely to their longitudinal axes comprise a conveyer provided with holders for the cigarettes which holders are adapted to be pivoted relatively to the conveyer transversely to their longitiudinal axes. As shown, two oppositely faced rows of cigarettes are transferred from a cutting drum 4 (Fig. 1) to alternate pairs of holders 14, 15 of a conveyer drum 1 rotatably mounted on a shaft 3. The row of cigarettes in the holders 15 is directly transferred to a grooved belt 5, the other row being guided in the holders 14 by guides 7 and 8. The holders are mounted between walls 13 and are pivotally mounted at their mutually facing ends. The other ends of the holders are provided with pins 16 which co-operate with guides 11 and 12 so shaped that during rotation of the drum the holders are pivoted towards each other and the cigarettes held in the holders 14 are transferred to the holders 15 for delivery to the belt 5 to form a single row of cigarettes all facing the same way. The holders 14, 15 are provided with bores 39, 36 (Fig. 4) which communicate with a bore 34 in a bearing pin 31. The pin 31 has a slot 35 communicating with a radial air duct in the drum 1 which in turn leads to slots 26 and 17 in the shaft 3 (Fig. 3). The slots are connected to a suction duct 22. An opening 23 in the shaft 3 leads to a compressed air duct 21. Suction is applied to the holders 14 via the slot 27 and to the holders 15 via a slot 26. In operation, suction is applied to holders 14 and 15 as pairs of cigarettes are taken from the drum 4, the suction being shut off from the holders 15 when the cigarettes are deposited on the belt 5. Suction is applied to the holders 14 until the point of transference of the cigarettes therein to the holders 15 when suction is cut off from the holders 14, a blast of air is applied through the bores 39 via the opening 23 and suction is again applied to the holders 15. In alternative arrangements, cigarettes may be held in the grooves of the holders by further guides instead of by suction (Figs. 5 and 6, not shown), and instead of the guides 11, 12 and pins 16 the holders may be pivoted by a rack and pinion arrangement (Figs. 7-9, not shown), or by guide rollers on the holders which co-operate with suitably shaped cam members (Figs. 10 and 11, not shown). In a further embodiment (Figs. 12 and 13, not shown) a divided turning conveyer drum is employed, each section of which is provided with a single set of holders which have a limited pivotal movement, the transference of the cigarettes from the holders on one section of the drum to those of the other section being effected by bevel-like intermediate conveyer members.

Title: Filter apparatus and method for purifying gas or air streams
IPC: B01D53/08
Filed: 1976-08-27
Abstract: A moving bed which moves downwards and consists of pourable or free-flowing contact material (2) forms a filter wall through which there is at least a twofold flow. The crude gas (28) first, at the bottom, encounters the already partially laden contact material (2), is deflected after flowing through the filter wall and is passed through the filter wall at least one more time further upwards, where it gives off the remaining contaminants to the at that stage less heavily laden contact material (2). The main purpose of the filter installation is to remove radioactive contaminants from the exhaust air of nuclear reactor plants. <IMAGE>
