Title: Improvements in and relating to controlling means for doors and the like
IPC: E05F17/00
Filed: 1936-11-24
Abstract: 481,990. Door - operating apparatus. WAYGOOD-OTIS, Ltd., and IRWIN, E. G. Nov. 24, 1936, No. 32112. [Class 65 (i)] The two leaves of double swing doors are interconnected to move in unison by a linkage including a pair, of elements which have a separating movement when the doors are opened and which are interconnected or acted on by restoring means opposing their separating movement and thus tending to close the doors. In the arrangement shown, each door pivot 2 carries a cam member 8 round which passes a section of chain 22 attached to the member 8 at one point. Slidably mounted on the frame between the doors are two bars 14, 15 having at their ends lugs 19, 20 and 17, 18 respectively, one of the chain sections being connected to the lugs 18, 19 and the other to the lugs 17, 20. A cylinder 23 pivoted to the lug 17 and sliding between rollers 35 has its piston connected to the lug 19, and contains a compression spring acting on the piston to oppose separation of the lugs 17, 19 by the opening of the doors ; the leverage of the spring is reduced as its stress increases by the effect of the cam members 8. The cylinder has an air-leak valve 32 at its inner end to give a checking action in the closing movement, and its wall is grooved to byepass the piston as it approaches the closed position ; preferably, one tapered groove and a shorter rectangular groove are provided. The position of the piston in relation to the grooves in the closed position is varied by adjusting the attachments of the chain sections 22 to the bars 14, 15. An additional connection between the doors is provided by an adjustable link 13 attached to crank pins 12 on extensions of the members 8. The doors may be held open by spring-pressed balls in the housings of the pivots 2 engaging recesses in the members 8. Instead of the restoring device 23 interconnecting the separating parts of the linkage, separate restoring means, which may be weight-operated instead of resilient, may be arranged to act on the linkage parts.

Title: A new process of hydrogenation of fats and oils
IPC: C11C3/12
Filed: 1945-11-28
Abstract: Fats and oils containing glycerides of unsaturated fatty acids are hardened by hydrogenation by contacting at normal temperature and pressure with hydrazine hydrate.  The calculated amount of the latter, for example 4 or 5 per cent of an aqueous solution containing not less than 80 per cent of hydrazine hydrate, may be stirred into sardine or other fish or olive oil and left overnight with hardening and deodorizing of the oil and liberation of ammonia.  The Specification as open to inspection under Sect. 91 states that the process is applicable to hydrogenation generally, and refers to hydrogenation of fatty acids such as oleic, palmitic and ricinoleic. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to J. van Alphen, Recueil des Travaux Chimiques des Pays-Bas, Volume 44 (1925), page 1064 et seq.

Abstract: In the cracking of liquid or gaseous hydrocarbons, to form ethylene and (depending on the starting material) propylene, higher olefines, combustible gas, gasoline and oil coke, in a fluidized layer of granular inert or carbonaceous solid at 630-900 DEG  C. and separating entrained solid in a cyclone, solid being returned through a down pipe, the cycle is kept free of deposits by introducing granular solid with the reaction and/or other gases to the inner upper boundary surface of the cyclone near the gas outlet pipe, the upper boundary surface being dome-shaped, frusto-conical or frusto-conical in stages inclining downwardly from the centre to the side so that the solid particles are forced against the inner upper surface by a component of the centrifugal force (see Group II).  The fluidized solid may be sand, sillimanite, corundum or preferably coke and steam and steam and/or oxygen may be added during the cracking. If coke from the fluidized layer is passed to the cyclone preferably the coarser particles are separated and these only used.  Sand, pumice, sillimanite, synthetic alumina stones or corundum may also be used alone or mixed with the coke.  The solids may be suspended in the reaction gases or extraneous steam.ALSO:In the cracking of liquid or gaseous hydrocarbons, to form ethylene and (depending on the starting material) propylene, higher olefines, combustible gas, gasoline and oil coke, in a fluidized layer of granular inert or carbonaceous solid at 630-900 DEG  C. and separating entrained solid in a cyclone, solid being returned through a down pipe, the cyclone is kept free of deposits by introducing granular solid with the reaction and/or other gases to the inner upper boundary surface of the cyclone near the gas outlet pipe, the upper boundary surface being dome-shaped, frusto-conical or frusto-conical in stage inclining downwardly from the centre to the side so that the solid particles are forced against the inner upper surface by a component of the centrifugal force (see Group II).

Title: Decontamination of chlorinated alkanes
IPC: C07C17/38
Filed: 1957-10-22
Abstract: A process of decontaminating the gaseous reaction product from a thermal alkane chlorination process contaminated with finely-divided carbon and/or water, comprises the steps of intimately contacting the gaseous product with liquid concentrated sulphuric acid or oil by simultaneously passing the gaseous product and sulphuric acid or oil through a first contactng zone and then through a following zone having a restricted cross-sectional area such that the fluid is thereby subjected to a pressure reduction of at least 1.8 p.s.i., the sulphuric acid, if used, being at least 90% concentration and the oil, if used, being a high-boiling hydrocarbon oil having a viscosity of not greater than 20 centipoises.  The oil should have a boiling-point above about 300 DEG  F.  Highly saturated paraffin oils are preferred but small quantities of unsaturated impurities may be present.  Pure paraffins, e.g. containing 10-16 carbon atoms, may be employed. The products produced by a process employing a fluidized bed may be treated by the process.  Examples relating to the treatment of a gaseous mixture containing ethane, hydrogen chloride, ethyl chloride, ethylene dichlorides, water and carbon, with sulphuric acid and of a similar mixture containing carbon, with hydrocarbon oil, are furnished.  Representative of other products mentioned which may be treated are methyl chloride, propylene dichloride and octyl chlorides.  An apparatus for carrying out the process is described.

[Also in Division F1] A gas-cooled nuclear reactor has six gas circulators 27 arranged in the annular space formed between the reactor core 25 and its outer prestressed concrete pressure vessel (not shown) encased in steel or the like. The concrete pressure vessel has a hexagonal outer surface and an insulated cylindrical inner surface and is closed at its upper and lower ends, the upper closing wall being provided with a number of openings for access to the core and circulators. Hot gas, preferably helium, passes from the core through ducts 74 to a turbine 28 in each circulator, and then through apertures 102 to a pair of steam generators 26. The gas passes from the steam generators through ducts 112 to a compressor 30 which forces the gas through a duct 118, a control valve 119 and a generally flat duct 76 back to the core. The core is formed of a generally cylindrical bundle of vertically-extending fuel and control rod elements surrounded by a reflector structure 58 enclosed in a cylinder 60. An emergency cooling system for the reactor may be provided in the annular space between core and pressure vessel.
