Title: Improvements relating to hydrocarbon separation processes using molecular sieves
IPC: B01D53/04
Filed: 1962-02-07
Abstract: A cyclic vapour phase process for the separation of straight-chain hydrocarbons from mixtures, for example a petroleum fraction boiling in the range 150-400 DEG  C., by means of a 5A molecular sieve comprises successive absorption, purge, and desorption stages, wherein the pressure in the absorption stage is 50-150 p.s.i. below the dew point pressure.  Non-absorbed hydrocarbons are removed during the purge stage, and straight chain hydrocarbons recovered during the desorption stage.  The feedstock may be mixed with a diluent of lower boiling point than the lowest boiling component of the mixture, for example nitrogen, the ratio of nitrogen to feedstock preferably being 0.5:1 to 5:1, which diluent material may also be employed as the purge material. In one form, wherein more than two absorbers are used, the effluent from the absorber being purged may be employed as the diluent.  The desorption step may be effected by elution with a straight chain hydrocarbon having a lesser number of carbon atoms than the lowest boiling straight chain hydrocarbon in the feedstock, for example butane or pentane.  The absorption stage is preferably operated at 300-400 DEG  C., 50-300 p.s.i.g., LHSV 0.1-5.  All the stages may be operated isothermally and isobarically. Specification 994,441 is referred to.ALSO:A cyclic vapour phase process for the separation of straight-chain hydrocarbons from mixtures, for example a petroleum fraction boiling in the range 150-400 DEG C., by means of a 5  molecular sieve comprises successive absorption, purge, and desorption stages, wherein the pressure in the absorption stage is 50-150 p.s.i. below the dew point pressure.

Abstract: 372,720. Coloured photographs. PROJECTOR AKT.-GES., 17, Lowenstrasse, Zurich, Switzerland. Feb. 14, 1931, No. 4980/32. Convention date, Feb. 14, 1930, Divided on 372,424. [Class 98 (ii).] A process of colouring a differentially hardened and swelled colloid relief image consists in first colouring the tops of the relief corresponding to the unexposed parts, with a colouring matter that will remain on the surface and not penetrate into the colloid (such as albumen azure dyes)., and then further colouring the image with a colour solution that will penetrate the unhardened parts (for example pinatype dyes), and/or containing mordant dyes which will colour the hardened parts. The relief may be reduced after the first colouring by exposing it to dry heat. Chemicals such as calcium chloride may be added to the bath used for producing the initial relief, in order to increase the absorption power of the unhardened colloid. Alcohols may be added to the moistening bath used to produce the relief in order to obtain a rapid surface drying.

Abstract: <PICT:0378342/IV/1> <PICT:0378342/IV/2> <PICT:0378342/IV/3> Thin films or skins obtained from solutions of viscose or of cellulose in Schweizer's reagent are subject to stretching both longitudinally and transversely during precipitation or after precipitation but while still in a plastic condition.  As shown in the drawings, a solution of cellulose in cuprammonium issues from a pouring device in a wide layer and without further support enters a precipitating bath 4 consisting of a caustic alkali solution.  The film 2 passes around rods or rollers 5, 6, and is drawn forward by a roller 7 by which it is stretched longitudinally.  It is freed from precipitating liquid by means of pressure rollers 8 and by washing and is treated with other liquids for removal of copper.  These treatments are combined with the width stretching.  Tensioning frames hold the film by means of claw members 10 connected with endless chains 15 through arms 16 and flat members 17.  The claw members are led away from each other by movement in rails 11.  The film may be stretched till it is much wider than the length of the pouring slot.  The film is sprayed with liquid from nozzles 12 and passes into a bath 13 of dilute sulphuric acid or water.  The claw members are released from the film which is then passed through other treatment baths and dried.

Abstract: 881,015. Ion-exchange. PERMUTIT CO. Ltd. Feb. 2, 1960 [Feb. 16, 1959], No. 5328/59. Class 46. Hard water enters resin bed 5 through inlet 1 and leaves through outlet 6. Exhausted resin leaves the bed through collecting device 9, is passed to the bottom of regenerator 13 and travels in countercurrent to brine regenerant introduced at pipe 16 by pump 15. The resin travels through the regenerating bed, passes to rinsing bed 27 via line 22 and returns to softening bed via pipe 32. The beds contain the usual resin collecting devices and screens to retain resin beads but not liquids. The movement of the cycle, which can be controlled electrically, is made in batches by shutting the appropriate valves and using the liquids, such as the hard water, rinsing water and regenerant stored in vessel 38, to displace a portion of resin. The regenerant in vessel 38 is originally displaced from the top of the bed by movement of resin from bed 5 in to regeneration bed 13. In a modification of the invention, the regenerant is stored in another vessel and is supplied to the vessel 38 by a continuously running pump.

Abstract: 1,239,767. Rolling. INSTITUT CHERNOI METALLURGII. 2 May, 1966, No. 5536/68. Heading B3M. [Also in Division F2] Apparatus for balancing inertia forces of a reciprocating stand (4) for cold rolling of pipes comprises a pair of fixed piston-cylinder assemblies each with the piston-rod 3 connected to the stand. Conduits 18, 20 interconnect the chambers A, B of the cylinder which is connected at 11 to a pressurized air source via a reducing valve (5) that automatically maintains a specified initial pressure in the cylinder. The two chambers initially communicate via open valve 19 but when the stand has assumed its normal working reciprocation the valve 19 is closed so that compression of air in each chamber in turn balances the inertia forces of the reciprocating stand. The piston is lubricated by oil flowing from a reservoir (6) mounted adjacent the piston cylinder assemblies through needle valves 28 and through conduits connected to the pressure inlet 11 of the cylinder while oil passes out of drain openings 21 of each chamber and passes through non-return valves 24 into the reservoir. Pressurized air in the chambers A, B acts on the surface of the oil through the valves 24 to cause the flow of lubricating oil to the cylinders.
