Patent GB-129654-A (GB)
Title: Improvements relating to the Working of Metals.
Inventor: GILBERT OLIVER CAVEN
IPC: B21C37/04
Filed: 1919-07-11
Abstract: 129,654. Gilbert, O. C. July 1, 1918, [Convention date]. Wire.-In a process for increasing the tensile strength of wire, the heat generated by external stresses in changing the physical form of the metal is compensated for so as to maintain the metal below the annealing temperature. The process refers particularly to making copper wire for electrical conductors. A billet, approximately 4 in. square is first reduced to a section of about “ in. diameter by rolling, the temperature of the metal being maintained below the annealing temperature. If the billet at the start is at approximately room temperature, artificial cooling may not be needed in the initial stages, but it is preferable to use a refrigerating agent. This may consist of a lubricant forced by a pump between the rolls and metal and over refrigerating coils containing liquid ammonia. The wire rod produced is then cold drawn through dies to reduce it to the required diameter, say 0.104 in. diameter or less, being subjected, before entering the die, to a refrigerating lubricant at about the freezing point of water, or even lower when working at high speed, so as to maintain the temperature below the annealing point. A tensile strength of over 114,000 pounds per square inch is thus obtained.

Filed: 1932-06-21
Abstract: In the destructive hydrogenation of carbonaceous materials the hydrogen is produced electrolytically by cathodic discharge from an electrolyte in contact with the carbonaceous material, e.g. p  coal tar &c.  High pressure chambers A, A<1>, B, B<1>, C, C<1>, are assembled in pairs so that each pair constitutes the electrodes of an electrolytic system supplied with current through terminals S, S<1>, S<2>,.  The chambers are connected laterally by pipes F<1>, F<1>, F<3>, provided with valves V<9>, V<10>, V<11> having insulating plates J and vertically by valved insulated connections V<12>, V<14>. Pipes P, P<1> are provided for washing out the apparatus and pipes M, N for leading off the products formed.  The chambers are connected by pipes <PICT:0403942/III/1> R<1>, R<2>, to hydraulic accumulators from which electrolyte and powdered coal are supplied to the chambers which are filled with expanded metallic bodies T resting on grids Q, the bodies T thus forming an extended electrode through which the electrolyte and powdered coal percolate, the carbonaceous material being hydrogenated by the nascent hydrogen evolved at the cathodic surfaces.  The vapors evolved and the excess hydrogen pass out through the pipe M while the anodic discharge is collected through the pipe N.
