Abstract: ABSTRACT OF THE DISCLOSURE A coupling includes a male member with a grooved configuration at opposed locations, and a hollow female member adapted to receive the male member.  The female member has a side wall with slots at opposed locations. A cam member exterior of the female member can rotate with respect to the female member.  The cam member has recesses which contain a generally U-shaped spring that includes a base and two arms.  The arms lie in slots of the female member when the cam member is in a first rotational position with respect to the female member, such that the arms protrude into the interior of the female member sufficiently to engage the grooved configuration of the male member.  The cam member is rotatable to a second position with respect to the female member, in which the recesses of the cam member and the slots of the female member are out of registry, so that the arms of the spring are forced apart sufficiently to allow removal of the male member.  The grooved configuration of the male member is adapted to receive the arms when the cam member is in the first position, thus retaining the male member within the female member.

Abstract: ABSTRACT "Digital integrated circuit comprising complementary field effect transistors."           Digital integrated C-MOS circuit in which two cross-coupled P-MOS transistors are connected via two separation tran-sistors (N-MOS) to two complementary switching N-MOS transistor networks. The gate electrodes of the separation transistors are connected to a reference voltage source. The switching speed of the C-MOS circuit is increased in that a) the voltage sweep across the logic network is reduced; b) the P-MOS transistor, which is connected via a separation transistor to a junction of the logic network to be charged, is slightly conducting and so is "ready" to charge this junction, and c) the separation transistor forms between the fully conducting P-MOS transistor and the junction to be discharged of the second logic network a high impedance which prevents the (still conducting) P-MOS transistor from charging the junction.

Abstract: ABSTRACT         The present invention constitutes a new and useful im-provement in a pliers-type hand tool wherein opposed jaws are spread apart for spreading or holding by engagement with internal surfaces thereof, objects such as chain links and snap rings.  It is comprised of a pair of movable handles, a first handle having a first jaw which is rigidly attached thereto and being pivotally connected to a work element which is in turn pivotally connected to the second handle and has a second jaw operatively opposed to the first jaw.  The invention also contains a toggle-type locking device which fixes the spatial relationship between the jaws when spread apart.  The distance between the locked jaws can be varied using an adjustment screw threaded into the first handle.  A re-lease lever pivotally connected to the second handle provides a fast and convenient mechanism For disengaging the locking device.       The jaws can be of various types.

Abstract: NEW PROCEDURE FOR COPPER CHLORIDE               AQUEOUS ELECTROLYSIS                      ABSTRACT           The process for extraction of copper metal from copper sulfide ore comprises leaching copper sulfide ore with ferrous chloride solution, to produce copper chloride, and electrolysis of the copper chloride using adjacent electrolytic cells separated by a semi permeable membrane.  The leach liquor containing copper chloride is introduced into the cathode cell containing an aqueous electrolyte, and brine is introduced into the anode cell. The semi-permeable membrane is permeable to monovalent cations, permitting the flow of sodium ions or other monovalent cations from the anode to the cathode during electrolysis.  Copper metal is withdrawn from the cathode and chlorine gas is removed from the anode for reclamation. The depleted copper chloride may be recycled for further electrolysis treatment.  The depleted leach liquor may also then be treated with zinc powder and removed for further processing to remove lead, precious metals and other elements. Zinc cations and ferrous chloride may be also recovered from solution for recyling.
