Abstract: 1,264,262. Separating hydrocarbons by extractive distillation. HEINRICH KOPPERS G.m.b.H. 19 Feb., 1970 [19 Feb., 1969; 29 March, 1969], No. 8048/70. Heading C5E. Mixtures of saturated and unsaturated hydrocarbons, e.g. in pyrolyses products, are separated by extractive distillation with morpholine and/or a substituted morpholine. Suitable morpholine derivatives are the N-formyl-2,6-dimethyl-, N- formyl-, N-oxyethyl-, N-hydroxyethyl-, N- acetyl-, N-phenyl-, N-hydroxypropyl-, dimenthyl-, N-hydroxyethyl-, and nitroso-, derivatives. A feed, containing paraffins, monolefins, diolefins, and possibly small amounts of more highly unsaturated hydrocarbons, is subjected to extractive distillation at super-, normal-, or sub-atmospheric pressure to provide a head product comprising paraffins or, depending upon the conditions, a mixture of paraffins and olefins and a bottoms product comprising the extractive solvent and, depending upon the conditions, olefins and more highly unsaturated compounds or diolefins and more highly unsaturated compounds. The head product can be further separated by normal or extractive distillation and the bottoms product can be separated by distillation into a head product comprising the unsaturated hydrocarbons and a bottoms comprising the extractive solvent which is recycled to the extractive distillation. A feed 1 consisting of a mixture of hydrocarbons is separated at 2 by extractive distillation to provide a head product 4 of paraffins containing little or no olefins and a bottoms stream 5. The stream 5 is separated in an extractive distillation column 6 to provide a head stream 8 of mono-olefins, which can be further separated in a distillation column 9, and a bottoms stream 12. The stream 12 is separated by distillation at 13 to provide a stream 17 containing the diolefins and any more highly unsaturated fractions and which can be further separated by distillation at 18 and a bottoms stream 14 containing the extraction solvent which is recycled after partial regeneration at 16 to the extractive distillation columns 2 and 6.

Abstract: 1297192 Treating textiles CHEMIEFASERKOMBINAT SCHWARZA WILHELM PIECK VEB 4 March 1970 10444/70 Heading D1L An apparatus for testing the behaviour of textiles in the finishing thereof comprises a container for the finishing bath, a perforated treatment drum, a pump circuit for circulating the finishing bath, and a test container arranged in series in the pump circuit or connected directly to the bath container. In operation the textiles to be dyed are placed in the perforated treatment drum 2 through opening 3. A solvent, perchloroethylene, mixed with the dyestuff, is fed into the bath container 1, and during the whole of the process the dyebath is circulated by the pump 5. Textile samples are placed in the test container 6, in the pump circulation of the apparatus with the valves 8 and 9 closed. These valves are opened when the container 6 is securely closed, thus allowing a partial stream of dyebath to be continuously pumped to the container 6 from pipe 14, so that the samples in the test container 6 are dyed under the same conditions as the textiles in the bath container 1. The amount of dyebath flowing through the container is regulated by valve 8, the amount being measured by measuring device 11 in pipe 15. When the results are to be tested, the valves 8 and 9 are closed, preventing dyebath flowing through the container 6; the dyebath in the container is let off with the help of valve 10, through pipe 17 into the coarse filter 4. The test container 6 can then be opened and the textile samples removed. In a second embodiment the test container is connected with the bath container (Fig. 2 not shown).

Abstract: 1336716 Nuclear power plant BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd and ENGLISH ELECTRIC CO Ltd 18 Dec 1970 [24 Dec 1969] 62815/69 Heading G6C The pressure vessel wall 4 of a gas-cooled reactor forming part of a direct-cycle gas turbine power plant accommodates a pre-cooler 2 and inter-cooler 3 which abstract heat from the gas coolant in its return passage from the turbine to the reactor core. The heat exchangers 2, 3 together with a heat exchanger 5 form an intermediate cooling circuit 1 through which water is circulated by a pump 8 through a non- return valve 9. Heat is abstracted from the circuit 1 by a further circuit 6 through which water is circulated by a further pump (not shown), the heat in circuit 6 being rejected to the sea or atmosphere. Should the power supply to the pumps fail, the water circulation practically ceases so that the water in the heat exchangers 2, 3 boils and at a certain pressure a safety valve 10 opens to vent the steam to atmosphere. At the same time a small pump 12, energized from an emergency source, is started to draw water from an emergency supply tank 11 to replace the loss through the valve 10. Thus the latent heat of vaporization of water is used to provide an emergency cooling system.

Filed: 1971-03-19
Abstract: 1344475 Coating tubular films IMPERIAL CHEMICAL INDUSTRIES Ltd 11 Feb 1972 [19 March 1971] 7296/71 Heading D1L In a method for coating plastics film with a flowable material (e.g. polyvinylidene chloride anchoring or heat-sealable top coating material) a film with the material coated thereon travels past a resilient scraping member biassed towards the film under a substantially constant pressure, the film contacting surface of the member having a particulate material evenly distributed and embedded therein. As illustrated the method is particularly suitable for coating a tubular film 1 which is passed downwardly through a closed applicator vessel 3 containing a latex of the coating material supplied from reservoir 5, the resilient scraping member forming a seal 6 at the downstream end of the vessel 3. The thickness of the coating layer may be adjusted by altering the-level of coating material in the reservoir 5 and thus the pressure in the vessel 3. The resilient member is preferably formed of silicone rubber and the particulate material is preferably an abrasive (e.g. carborundum powder having an average particle size of 140 microns). The coated film may be heated after coating and/or uni- or biaxially oriented. An example relates to the coating of a tubular polyethylene terephthalate film with a latex of vinylidene chloride/acrylonitrile copolymer.
