Title: Method of producing metal sponge and means therefor
IPC: C21B13/00
Filed: 1929-09-30
Abstract: In the production of metal sponge from oxide-containing materials in which finely divided ore and reducing agent are briquetted with a binding agent, the briquettes, preferably after drying, are placed in casings or shells and heated to the temperature required for the reduction.  In the production of iron sponge, using carbon as reducing agent, the shells are heated in a furnace chamber to about 1100 DEG  C.  Ferro-silicon is specified as the reducing agent in the case of chromium, and a reduction temperature of 1200 DEG  C.  Excess carbon is used when a high carbon-content metal is required.  The shells and contents after reduction may be melted in the same or in a separate furnace.  The shells are made of sheet iron or of a refractory material.  The charge within the shell is covered with a layer of carbon.

Abstract: 938,236. Making copper foil. CLEVITE CORPORATION. Aug. 24, 1961, No. 30543/61. Class 41. Copper foil is produced by electroplating copper on to a drum cathode which has a surface of crack-free chromium from which complex chromium compounds and oxides have been removed by dressing. This dressing is performed so that the impurities are removed primarily by a cutting action and with the minimum of heat generation. Immediately after the dressing the drum is plated to prevent atmospheric contamination. During the plating and stripping process only 3% of the drum surface is uncovered by copper plate. In the Figure the anode is in the form of copper bars 20 and the electrolyte 12 is circulated by means of the pipe work shown at 25, 26, 27 and 28. The weight of the deposit is determined by the speed of rotation of the drum. The temperature of the bath is 140‹ F. and the current density 135-145 amps/sq. ft. A suitable plating solution comprises: 50 g/1 copper or 200 g/1 copper sulphate, 100 g/1 sulphuric acid, " Goulac " (Registered Trade Mark) 1 p.p.m., hide glue 1 p.p.m., chloride 0.035 g/1.
