Abstract: ABSTRACT OF THE DISCLOSURE           A method of extracting primary zinc metal from ore concentrates is described.  The method includes pro-viding first and second electrolytic cells, the first cell being intended to receive an acid zinc sulfate solu-tion derived from an ore concentrate, and having an anode which is insoluble in said solution, and the second cell containing an alkaline electrolyte and having a cathode which is insoluble in said electrolyte.  A common electrode is also provided which is insoluble both in the acid zinc sulfate solution and in the alkaline electrolyte.  The common electrode can be transferred between the first cell, in which it acts as a cathode, and the second cell, in which it acts as an anode.  The zinc sulfate solution is subjected to electrolysis in the first cell with the common electrode acting as a cathode, thereby causing primary zinc metal to be deposited as a coating on the electrode. The coated electrode is transferred from the first cell to the second cell and the alkaline electrolyte in the second cell is subjected to electrolysis so that the primary zinc metal is transferred from the common electrode to the cathode of the second cell in a sponge-like form.  The zinc sponge is mechanically removed from the cathode of the second cell.

Abstract: ABSTRACT OF THE DISCLOSURE      A motorcycle boot has an upper wrap-around shell, closed by a buckle and strap, which overlaps a lower vamp shell having a plurality of forward and rear tapering fingers which extend into the upper shell to allow hinging movement of the upper shell.  Flexible liners are inserted into the vamp to custom fit the vamp shell to a wearer's foot.  An interconnecting hinge assembly includes a pivot pin, journalled in the upper shell, and slidably mounted within a slotted plate attached to the lower shell, to allow the upper shell to pivot forwardly and rearwardly and rock sideways.  The base of the lower shell, with a steel plate embedded in the instep arch, is covered by a replaceable sole attached by adhesive which forms a rupturable seal.  To waterproof the boot, a flexible cylindrical liner is sealed to the lower vamp and extends through the upper shell, with the liner top being folded down and externally attached to the upper shell.

Abstract: MULTIPLE OPTICAL CORE FIBER                         ABSTRACT         A multiple optical core fiber and method for manufac-turing it.  Two or more chemical vapor deposition type preforms are fused with a hydrogen-oxygen torch and then etched in a solution of 50% hydrofluoric and 50% nitric acid.  A hollow quartz tube is subjected to internal gas pressure while a hydro-gen-oxygen torch is passed along it.  This expands and cleans the tube.  The chemical vapor deposition preforms are inserted within the expanded tube which is again subjected to the torch to collapse it about the preforms.  A nearly solid glass rod with two or more optical waveguide cores is thereby formed.  This mul-tiple core preform may then be drawn into a multiple core fiber which can be utilized for the transmission of light pulses.
