Title: Method for the electrolytic deposition of copper on aluminium and its alloys and the products obtained therewith
IPC: C25D5/18
Filed: 1974-07-09
Abstract: 1423928 Electro-depositing copper on anodized aluminium R COLALE 9 July 1974 [9 July 1973] 30275/74 Heading C7B An A1 or A1 alloy body e.g. plate is electroplated with Cu by immersing the degreased and pickled body in an electrolyte bath containing Cu (and preferably K 4 ) pyrophosphate with pH between 8À2 and 9À7 and temperature between 50 and 65‹C, first as anode then as cathode by reversing polarity without withdrawing the body from the bath, the counter-electrode being at least one Cu plate or bar, and regulating the voltage so that a CD of between 1À6 and 2À4 A/dm<SP>2</SP> of body surface passes during anodizing, and of between 0À2 and 0À9 rising to a maximum of between 5 and 10 A/dm<SP>2</SP> of body surface during electro-plating, the voltage being reduced to between 0À3 and 0À7V at the end of the first stage. For offset printing, A1 cylinders electro-plated with Cu as above may be further electro-plated with Ni and/or Cr; for electronics, the Cu electro-plate may be coated with Sn-Pb soldering alloy. Degreasing may be effected in C 2 HCl 3  and etching in NaOH then HNO 3  solution. The bath may also contain inorganic salts of alkali metals, e.g. oxalates or citrates, to obtain shiny and brilliant Cu deposits.

Title: Improvements in or relating to hydrostatic extrusion processes
Inventor: GREEN DEREK
IPC: B21C23/00
Filed: 1964-07-31
Abstract: 1,111,351. Extruding. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 26 July, 1965 [31 July, 1964; 7 July, 1965], Nos. 30277/64 and 28823/65. Heading B3P. A billet 180 is extruded through a die 179 by a combination of hydrostatic and mechanical extruding forces. Surrounding the billet and enclosed in a cylinder 150 is a fluid which has communication with a chamber 123 by means of a bore 170 in an extrusion ram 146. The ram is rigidly attached to the outside of the chamber 123 and is used to exert an axial pressure on the billet while the fluid surrounding the billet exerts a hydrostatic force. A plunger 118 rigidly attached to a main ram 108 slidable in a cylinder 109, moves within the chamber 123 to effect pressurization of the fluid and to simultaneously exert an axial force on the ram 146 through the medium of the fluid. During extrusion, the chamber 123 together with the ram 146 normally move towards the left, but the chamber can be wholly or partly restrained from movement by means of piston cylinder units 134, 135 operatively connected to the chamber in order to control the amount of axial force exerted by the ram 146 on the billet. By stopping movement of the chamber completely the resulting extrusion is purely hydrostatic. The ram 108 is pressurized by a motor driven pump 177 delivering fluid through a valve 178 and is independently movable by piston-cylinder units acting on a crosshead 112. The chamber 123 and cylinder 150 are similarly axially movable by means of piston-cylinder units to allow insertion and removal of the billets. On completion of extrusion the cylinder 150 is moved to the right and the remainder of the billet is sheared off by either a horizontal or a vertical shear assembly 174. Alternatively the end of the billet may be sawn off. A shear ring 181 (Fig. 5, not shown) is discarded after extrusion. A back pressure tube 175 allows brittle materials to be extruded against a pressure exerted by a fluid in the tube.
