IPC: B03B5/62
Filed: 1956-07-06
Abstract: 843,536. Washing granular materials; mixing appliances. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 7. 1957 [July 6, 1956], Na. 21041/56. Classes 82(2) and 86 [Also in Group I] Liquid containing suspended solids is pumped at 14, Fig. 1, from a classifier 41 to the tangential inlet 23 of a vessel 11 whence liquid containing solids, if any, below a certain grade (grade being a function of particle size, shape and density) is discharged by a siphon 13 and weir 45, while the remaining solids fall freely through the outlet 11b, at the base of the vessel, which is slightly submerged below a body of liquid (not necessarily of the same kind as that entering the vessel 11) in an open-topped receiver 12. There is no liquid flow into or out of the column at 11b. Hence solids (e.g. sand), may be transferred from liquid (e.g. sea water) in the column to a different liquid, which may also be of lower density (e.g. fresh water) in the receiver 12. There may be an independent flow of liquid through the receiver 12. The upward velocity at the separation level is rendered constant across the cross-section of the vessel 11 by vertically-arranged corrugated sheets in contact, or by a honeycomb structure 25, into which tapering needles 26 extend. The centrifugal pump 14 is operated as a constant head device. The level in receiver 12 is to some extent selfadjusting. Larger fluctuations, or changes caused by adjustment of valve 15 or valve 16 are compensated for by a needle valve 17 linked to a float 22 in a stilling pot 21. The pump may be replaced by a flume discharging into an open hopper having a control valve. The outlet of vessel 11 may be provided with a valve 30, Fig. 4, which may be raised vertically to raise, and close the aperture in a flexible sleeve 31 by a wire 39 and links 35, 32.

Title: Separation of uranium, plutonium and fission products from neutron-bombarded uranium
IPC: G21C19/48
Filed: 1962-06-04
Abstract: Plutonium and fission products are separated from uranium in a neutron-bombarded uranium mass by dissolving the mass in the metallic condition in a molten zinc-magnesium alloy containing 10-18% by weight of magnesium, adding more magnesium to obtain a composition corresponding approximately to the zinc-magnesium eutectic so as to precipitate uranium, and separating the uranium from the eutectic containing dissolved plutonium and fission products.  Preferably the dissolution and precipitation are carried out at 800-850  DEG C. in helium using a quantity of zinc about five times the weight of the uranium.  If an oxidic fuel is to be treated, the oxides are reduced to metals by additional magnesium included in the alloy.  Plutonium and fission products may be concentrated by distilling zinc and magnesium from the eutectic alloy.  Specification 867,057 is referred to.

Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C3/02
Filed: 1935-08-01
Abstract: Hydrocyanic acid is obtained by reacting nitric oxide with an amount of a hydrocarbon or mixture of hydrocarbons containing at least 2 atoms of carbon for each molecule of nitric oxide in the presence of 2 to 10 volumes of an inert gas per unit volume of nitric oxide, at a temperature of 800--1400 DEG  C., in the absence of a catalyst. Nitrogen is a suitable inert gas.  The reaction mixture may also contain water vapour and oxygen.  Ammonia may be catalytically oxidized with excess of air, the hot oxidation gases being used directly for making the reaction mixture.  The ammonia may be oxidized with oxygen instead of air, an inert gas such as nitrogen being subsequently added.  Suitable hydrocarbons include methane, ethane, butane, propane, vaporized gasoline, ethylene, propylene, benzene and naphthalene.  The reacting mixture should be preheated to about 600 DEG  C.  The whole of the necessary heat may be supplied by the addition of sufficient oxygen or air to the preheated reaction mixture.  The reaction may be conducted in an electrically heated silica tube.
