Patent GB-937485-A (GB)
Title: High energy rate extrusion of uranium
IPC: C22F1/18
Filed: 1962-06-18
Abstract: A method of extruding fine grain natural uranium suitable for reactor fuel, comprises heating a pre-formed natural uranium slug to 1000-1100 DEG  F., extruding the slug at a pressure sufficient to cause the transformation of the product emerging from the extrusion die into the beta phase, and rapidly cooling it.  This enables extrusion to take place in the alpha phase with automatic transformation into beta phase and the rapid cooling produces a fine grain structure and obviates further heat treatment. Machined hollow slugs heated in an argon atmosphere are extruded into a tube by a high-speed ram actuated by pressure gas, and having a machined carbon dummy block which eliminates any discard. A lubricant, consisting of an aluminium graphite suspension in a quick evaporating organic solvent, is sprayed on to the slug and the pre-heated extrusion tools.  The extruded tube emerging from the die is trapped in a catch tube stuffed with rock wool and is rapidly cooled by compressed air or water.  Specific examples are given.

[Also in Divisions C3 and D1] Leather-substitute sheet material may be produced by bonding a substrate to a porous sheet of polymeric material contains pores inclined at an angle of less than 80 degrees to the plane of the sheet, the pores having a length of 0À03 to 10 mm. and a diameter of 0À003 to 1À0 mm. It may be prepared by immersing a layer of polymer solution on a support in a coagulation bath for the polymer solution to rapidly coagulate the upper portion of the layer of solution and to form macropores in the inner portion of the layer, stressing the upper portion in a transverse direction, completing the coagulation of the polymer and finally removing the coagulated polymer from the support. Stressing of the upper portion may be achieved by the action of a rotating roll or by inclining the support at an angle of more than 20 degrees to the surface of the bath before or after immersion of the coated support in the coagulation bath. Polyurethane elastomers are the preferred polymers; others are mentioned. In a typical example, a polyurethane elastomer dissolved in dimethylformamide containing carbon black as pigment was flowed on to a polyethylene sheet, the sheet was introduced into a water bath at an angle of 80 degrees, the polyurethane coagulated and the sheet was then dried and stripped from the support. The sheet material may be bonded to substrates such as woven, knitted and unwoven fabrics, laminates of woven and unwoven fabrics, laminates of knitted and unwoven fabric, any of these fabrics impregnated with a polymer and paper. It is preferred to bond the substrate with that surface of the porous sheet which has not been in contact with the support. Specific substrates used in the examples are (i) one prepared by needle punching staple fibres from a mix spun filament of nylon-6 and polystyrene to produce an unwoven fabric which is then impregnated with a polyurethane elastomer solution followed by coagulation of the elastomer, extraction of the polystyrene and slicing of the surface to give a smooth surfaced substrate, (ii) cotton flannel, (iii) an unspecified unwoven fabric. The product may be embossed to make it more similar to leather.
