Abstract: The invention provides a method of transporting a liquid A past or around a barrier, by adding a solute S to liquid A on one side of the barrier and correspondingly removing solute S from liquid A on the other side of the barrier, the solute S being such as to change the density of the liquid A when dissolving in it, thereby providing a motive force for its motion around the barrier. An example of the application of the invention is in a two-part electrolytic cell (1) comprising electrowinning and electrofining half cells (2 and 3, respectively), wherein the metal, solute S, is electrowon into a liquid (16,16a), liquid A, on one side of the cell's common electrode (4), the barrier, in the electrowinning half cell (2), and electrolytically removed from the liquid (17,17a) on the other side of the common electrode (4), in the electrorefining half cell (3).

Abstract: The invention is concerned with a spinner fishing lure of novel design, construction and function, which eliminates the conventional wire harness commonly used in the prior art. The inventive lure is completely snagless and weedless, and it is capable of being retrieved at any desired depth. Upon retrieval, the lure moves from side-to-side and zig-zags in imitation of the movements of a swimming bait fish, and it also pulsates and vibrates vigorously to additionally attract any fish in the vicinity. Additional features and advantages of the inventive lure are set out in the detailed description.

Abstract: Dyes which, in the presence of molecular oxygen, promote the formation of cytotoxic oxygen are used to combat internal parasites in warm blooded animals. Internal parasites having the dye incorporated therein are exposed to electromagnetic radiation to initiate one or more lethal oxidative reactions. The photosensitized parasites may be in the infective stage thereby breaking the life cycle. This reduces or prevents reinfection and the need for traditional anthelmintics.

Abstract: An artificial fishing lure is disclosed including first and second rearwardly diverging frame members that are connected by an eye means for attaching a fishing line. A weight and fish hook are carried by the first frame member, and a unique movable or pivotable arm member is connected to the trailing end portion of the second frame member. One or more buzz blades or spinner blades are mounted on the arm member or attached to the trailing end thereof. The arm member is free to move or pivot back and forth and up and down at the point of attachment at its leading end portion, but the trailing end portion and the buzz blades and/or spinner blades carried thereby are prevented from moving toward the first frame member a distance sufficient to foul any part of the lure. The lure is very versatile and is further characterized by markedly increased sound and action. The arm member and blades assume a vertical position in a free fall and the blades imitate an injured bait fish.
