Abstract: A fiber optic wand novelty device for children utilizing a caricature illuminated in a constant color with a plurality of optical fibers extending therefrom. A mount for the optical fibers is secured to an illumination device and includes a color pallet so as to cause colored tip illumination of the optical fibers. The holder of the fibers may be of a fixed color and serves to orient the proximal end of the optical fiber bundle directly over the light source. Accordingly, the colored light is conveyed through fibers, with the longitudinal lengths of the fibers producing solid, whitish light. The holder therefore allows the caricature head to be made of a predetermined color and allows for a realistic likeness under normal lighting conditions and a predetermined colorization or illumination when placed in a darkened environment.

Abstract: The instant invention teaches the use of conventional chemiluminescent constituents of different colors disposed within at least two chambers [place] placed in a parallel or helically woven pattern. Each chamber sets forth a distinct color that when viewed in combination with an adjoining color emitting chamber, provides a combination color or rainbow type product that cannot be obtained by mixing dyes in a single chamber. The invention further provides [the unique] various color combinations not commonly available due to dye incompatibility.

Abstract: The instant invention teaches the use of conventional chemiluminescent constituents, admixed or separated, disposed within at least two juxtapose chambers in a parallel or helically woven pattern. The chamber each containing a distinct color that when viewed in placement of the instant invention, provides a combination color or rainbow type product that cannot be obtained by mixing dyes in a single chamber. The invention further providing a means for allowing new color combinations not available due to dye incompatibility.

Abstract: A method of fabricating chemical lighting devices, comprising coextensive inner and outer tubes, wherein the inner tube contains multiple, segregated oxalate components, is described. Upon activation the device generates a distinct multi-color array of light.

Abstract: A metal powder e.g. copper or zinc, is produced from a dilute aqueous solution of the metal by subjecting the dilute aqueous solution to electrolysis in a cell having a rotating cylinder cathode and in accordance with the equation:I = KCV.sup.xwhere I is the current density, K is a constant for a given cell, C is the concentration of metal ion in aqueous solution, V is the peripheral velocity of the rotating cylinder cathode and x = 0.7 to 1.0. A diaphragm cell is preferably used. Dilute aqueous solutions treated include mining liquors and viscose rayon plant effluent.This invention relates to metals and is particularly concerned with the recovery or extraction of metals in powder form by electrolytic means.
