Title: Isotope enrichment esp of uranium by vortex tube - using light diluting gas and flat vortex angle
Inventor: FUHSE WILMAR DIPL PHYS DR ING
IPC: B01D59/18
Filed: 1975-02-12
Abstract: An appts. for sepg. gas mixts., esp. for uranium isotope sepn. comprises a hollow vessel into which the mixt. is introduced at high eccentric or tangential speed to create a high speed vortex; in addn. to the mixt. of gases to be sepd., a quantity of a gas of considerably lower mol. wt. is also introduced. Pref. a high inlet speed is obtd. by a constriction of the inlet duct, followed by a widening out like a Laval nozzle to create supersonic speed. Used esp. for uranium enrichment. By using a 'vortex tube' principle, as a modification of the 'sepn. nozzle' principle, and by admixing allighter gas to increase considerably the inlet speed and energy, more efficient sepn. is achieved. The compression ratio is improved, e.g. to about 4:1. It is estimated that by increasing the rational angle of the gas to more than 360 degrees, and using a mixt. comprising 95% helium and 5% UF6, the energy demand is about one tenth that required for the diffusion process.

Title: Halogenated unsaturated hydrocarbons esp. vinyl chloride prodn. - using fluidised bed to transfer heat from exothermic to endothermic zones
Inventor: SHEELY HAROLD R
IPC: B01J8/24
Filed: 1976-06-30
Abstract: Prodn. of halogenated, unsaturated hydrocarbon is effected by simultaneous and common halogen substitution of a hydrocarbon and thermal decomposition of an alkyl halide. An exothermic reaction of a halogen with a selected hydrocarbon in the vapour phase is carried out in a first reaction zone (I) in the presence of fine particulate solids, so that a selected alkyl halide comprising >=2 halogen atoms in the molecule is formed, accompanied by heat production; this heat is absorbed by the solid particles; Simultaneously, an additional quantity of the selected alkyl halide is introduced into a second reaction zone (II) the solid particles are transported from (I) to (II) where they give up their heat to promote dehydrohalogenisation of the additional alkyl halide in this zone, thus producing a halogenated, unsaturated hydrocarbon with the same number of carbon atoms in the molecule as the alkyl halide. Used partic, for the prodn. of vinyl chloride. Effective transfer of the considerably heat produced (I) to (II) where it is required, is attained.

Title: Free running material storage container - with insert absorbing static pressure and metering flow rate to discharge opening
Inventor: LERCH FRIEDRICH WILHELM DIPL I
IPC: B65D88/64
Filed: 1976-12-22
Abstract: A device with a storage container for free-running bulk material to charge, e.g. an injection moulding machine, has a discharge opening at the botto which is connected to a worm conveyor, for example leading to an injection die. An insert is arranged stationarily in the container to absorb and equalise the pressure exerted by the charge and to pass a metered amt. of the material. Arrangement prevents fluctuations in the feed rate to the die, caused by fluctuations in the filling level of the container, which would cause webs if the pressure is too high, or inadequate filling of the mould if too low.
