Abstract: A device for applying electric current to mass. The device includes a vessel having a cylindrical wall with a stirrer arranged in the vessel. The stirrer is mounted on a first end of a rotationally driven stirrer shaft. The stirrer shaft with a spacing is enclosed by a first electrode. The first electrode is immobile and fixed to a lid arranged to cover an open cross-section of the vessel. The cylindrical wall forms a second electrode, wherein the first electrode and the second electrode are connectable to opposite polarities of a current source.

Abstract: The inventive disclosures described herein pertains to an improved clasp-type device for connecting two ends of a wrap-around personal-adornment/jewelry item, such as a necklace, bracelet, or anklet. The improved jewelry clasp provides for both easy and secure coupling of two ends of a wrap-around jewelry item, while providing a decorative “hiding” of the clasp. In variations, the improved jewelry clasp can appear as just one of several ingots/charms that the wrap-around jewelry item may contain. Various other practical applications of the improved jewelry clasp are also disclosed.
