Filed: 1970-07-30
Abstract: 1275014 Casting composite articles BATTELLE MEMORIAL INSTITUTE 30 July 1970 [31 July 1969] 37012/70 Heading B3F [Also in Division C1] A composite material consists of porous carbon bodies embedded in a metal, the carbon bodies having been made by carbonizing a porous organic substance in a non-oxidizing atmosphere. It may be made by placing the porous carbon bodies in a mould, placing a piece of wire netting over the carbon bodies, placing lumps of metal on the wire netting, and then heating the mould so that the metal melts and fills the space between the cerbon bodies. The latter may be coated with a metal, or a metal carbide produced by heating a coating of the corresponding metal, prior to casting to improve the wetting of the carbon bodies by the metal being cast. This may also be achieved by adding Ti, Fe, Si, Zr, Hf, V, Nb, Ta, Cr, Mo or W to the metal being cast. To decrease the wetting action Cu, Zn, Ag, Cd, In, Sn, Sl, Au, Pb or Bi may be added to the metal being cast, or a layer of oxide may be formed on the surface of the metal, e.g. by admitting traces of oxygen into the atmosphere of the furnace in which the casting operation takes place. The casting operation may be carried out at pressures above or below atmospheric in the presence of argon. A deoxidizing slag may be used over the top surface of the molten metal. The metal may occupy all or only a part of the space between the carbon bodies; in the latter embodiment part of the metal is removed while it is still molten so that the only metal which is left is that which adheres to the carbon bodies. Some of the carbon bodies may be eliminated from the composite material, e.g. by combustion in an oxidizing atmosphere. Examples describe the preparation of composite materials having aluminium, copper and iron respectively as the metal.

Abstract: 1,007,212. Processing radioactive waste. ATOMENERGIKOMMISSIONEN. Sept. 16, 1964 [Sept. 24, 1963], No. 37742/64. Heading G6R. Radioactive waste in the form of cellulosecontaining material contaminated with radioactive material is destroyed, so that the radioactive material can be isolated as a concentrate able to be handled and stored, by suspending the cellulose-containing material in cold concentrated sulphuric acid (i.e. sulphuric acid at or near normal room temperature) and conducting the suspension below the surface of concentrated sulphuric acid maintained at a temperature of from 300‹ to 330‹ C. and to which is added a catalyst, e.g. selenium, for oxidizing the cellulose-containing material to carbon dioxide and water. Destruction by this method proceeds without development of smoke and the gas escaping consisting of carbon dioxide and sulphur dioxide as well as some water and sulphuric acid vapour only carries off a small amount of droplets, no greater than what is usually carried off by distillation. By way of example, 5 kg. contaminated cellulosecontaining material is stirred into a suspension in 50 1. cold concentrated sulphuric acid and this suspension is pumped through a tube for 1 hour below the surface of 100 1. concentrated sulphuric acid at 310‹ C. to which 1 kg. selenium has been added as catalyst and which is contained in a closed quartz vessel fitted with a fractionating column. During the destruction of the cellulose-containing material, about 50 kg. sulphuric acid, 8 kg. carbon dioxide, 24 kg. sulphur dioxide and 12 kg. water are removed. Most of the radioactive material stays in the sulphuric acid in the quartz vessel, and can be isolated as a concentrate by evaporation of the sulphuric acid. The escaped gas can, after condensation of sulphuric acid vapour and removal of surplus water, be treated in known manner to regenerate sulphuric acid from the sulphur dioxide so that only carbon dioxide finally escapes.

Title: An electrolytic process for producing halogen gases and the apparatus therefor
IPC: C25B9/19
Filed: 1961-10-25
Abstract: <PICT:0959846/C3/1> Halogens are produced by electrolysing anhydrous or concentrated halogen acid, especially HCl and HF, using a hollow microporous cathode of fuel cell type, e.g. carbon impregnated with Ni, Ag, Au, or Pt, to which oxygen is admitted to form water, thus removing the hydrogen, and reducing the decomposition voltage to be applied. A permeable membrane of selective ionic type surrounds the cathode. A suitable apparatus consists of a chamber 20 with a lid 22 clamped and sealed at the top in which is mounted an anode 42 which may be for example graphite, tantalum, titanium, silicon carbide, platinized metals, or aluminium. The cathode 42 is mounted concentrically within the anode, and is of microporous carbon in which is distributed a metal catalyst, e.g. Ag, Au, Pt, or may be a microporous mat of sintered Ag or Au. A surrounding ion-selective permeable diaphragm 48 is mounted either spaced from the cathode, or in contact with it. The sealing material used as gaskets and jointing may be P.T.F.E. when fluorine is made, or P.V.C. when chlorine is made.  In operation, HF is admitted through a port 30 under slight pressure and contains little KF or NH4F to render it conductive. Oxygen is admitted through a port 46 and a small amount of H2SO4 through an inlet 54.  The water formed in the cathode space, together with some HF, passes out with the H2SO4 through an outlet 56, and the fluorine produced passes out through a pipe 32.  For example, anhydrous HF containing 10% of KF was treated at 20 mA. per sq.cm. current density.  With nitrogen admitted into the cathode a voltage of 2.9 U. was required, with air 1.8 U.  Specification 911,386 and U.S.A. Specifications 2,636,851, 2,730,768, 3,103,473 and 3,103,476 are referred to.
