Title: Improvements in and relating to the production of powders of metal, alloy or other electrically conductive material
Inventor: DARLING ALAN SYDNEY
IPC: B22F9/14
Filed: 1960-12-14
Abstract: In a method of and apparatus for making electrically conductive powders, an electrical circuit is established between one or more pairs of electrodes through a layer of conductive <PICT:0924202/III/1> particles wetted by a di-electric, and the particles are agitated to cause sparking which results in spark eroded powder.  A container 1 for a dielectric 3 is connected by a pipe 4 to a draining valve 10 and an axial flow pump 5 which forces dielectric through a pipe 8 into a tray 13 and thence, by overflowing, back to the container 1.  The tray 1 is made of plastics and contains a number of positive and negative electrodes 15 of hemispherical form arranged in rows and columns.  Covering these electrodes is a layer 18 of scraps or particles of carbon to be powdered.  The tray is supported by an air vibrator head 14, which is switched on at the same time as the axial pump.  In a modification the columns of hemispherical electrodes are replaced by semi-circular section bars placed in rows flat side down on the tray.  Connected to the pipe 9 is an otherwise closed container full of dielectric; the valve 10 may be open during erosion, in which case some of the powdered carbon sinks from the circulating dielectric into said container.  Alternatively the valve 10 may remain closed during erosion.

An adjusting wheel 7 permits the deflector member to be rotated up or down and a similar wheel (10, Fig. 1, not shown) enables the vanes and spindle to be rotated to deflect the airflow left or right. In a modification, a sleeve may be fitted around the deflector member or between the latter and the vane assembly. The sleeve has apertures in register with apertures 6, 6<SP>1</SP> so that relative rotation of the sleeve and deflector member adjusts the air flow.

Title: Method of producing pure copper in the form of rods or bars
Inventor: MAY HENRY GEORGE
IPC: C25D1/04
Filed: 1962-11-22
Abstract: <PICT:1021087/C6-C7/1> Refined copper bars are produced using an anode of impure copper by electrodeposition on the conductive portions of both surfaces of a cathode 1 consisting of a flat plate 4 on which are disposed electrically insulating portions 7 defining a spiral or other sinuous conducting track 8, the deposited copper being stripped from the cathode to yield a bar which is subsequently joined to others to form a continuous length.  The electrically insulating portions 7 may be formed by upstanding fins of insulating material form by a strip inserted into a spiral groove in a stainless steel plate 4 or a similar strip disposed flush with the surface of the plate, or an insulating lacquer may be applied to define a spiral track 8 either on a flat plate or by coating the tops and sides of a plate having integral upstanding fins.  The centre of the spiral and the regions of the cathode outside the track area are preferably coated with insulating material.  The track 8 may be treated to facilitate removal of the deposit.  Several cathodes 1 may be suspended in the electrolysis bath with anodes adjacent each face. Even if the cathode deposits extend over the insulating portions, a line of weakness is formed which allows parting of adjacent turns.

Title: Purification of sand
Inventor: REEVE LEWIS
IPC: C03C1/02
Filed: 1964-10-30
Abstract: Sand is purified by fluidization with HCl in a bed at a temp between 400 DEG  and 800 DEG  C., The HCl is introduced into the bottom of the chamber at a temp. below 400 DEG  C. and the sand is introduced at a temp. high enough to bring the bed to the selected reaction temp. The effluent gases may be cooled, e.g. with a cooler gas, HCl gas being preferred, as they leave the chamber, e.g. to below 400 DEG C.  The HCl may be separated from the volatile metal chlorides, e.g. Fe, Cr and Mn chlorides and steam and recovered and recycled.  This recovery can be achieved (a) by scrubbing the cooled gases with aq. HCl, gaseous HCl remaining which is cooled to below 100 DEG  C., and dried, e.g. with conc. H2SO4, or (b) by cooling the gases to below 350 DEG  C. and scrubbing with conc. H2SO4, any H2SO4 mist in the recovered HCl being filtered out or electrostatically precipitated, or (c) by cooling the effluent gases to a temp. at which the metallic chlorides are condensed in an anhydrous state, e.g. 180 DEG  C. the remaining gaseous fraction being scrubbed with conc. H2SO4.  Fresh 95% H2SO4 may be added to the scrubber.

The cylinders are concentric with the node circles and have inside diameters essentially equal to the diameters of the node circles respectively. Three node circles (11, 12, 13), Fig. 4 (not shown), may be generated to correspond with three concentric right circular cylinders. The diaphragm 2 may be of metal and form one electrode of the piezoelectric element 3 or it may be made of synthetic resin. The diaphragm 2 is spaced from the cavity 51 by a number of projections 4.
