Abstract: A positive displacement rotary apparatus comprising a rotor having opposed faces on opposite sides thereof; a housing around the rotor and having opposed internal side walls facing the opposed faces of the rotor; and a plurality of circumferentially spaced vane means extending slidingly through the rotor in a direction substantially parallel to the rotational axis thereof and disposed radially outwardly from the axis of rotation of the rotor on substantially the same radius. An annular recess which periodically varies in depth and width over its length is formed in each of said internal side walls of the housing concentrically with respect to the axis of rotation of the rotor. The annular recesses slidingly receive opposite ends of the sliding vane means, and the bottoms of the recesses are equidistantly spaced from each other at all aligned points over the length of the recesses as measured along any one vane means having its opposite ends in the recesses.

Abstract: A fishing lure which includes a rigid body of generally fish-shaped configuration tapering from mid-section to tail, and an elongated, flexible resilient streamer element connected to the tail of the rigid flotation body.

Abstract: A bolt action for a repeating rifle including an elongated hollow bolt having formed thereon, circumferentially spaced, axially extending rails which cover a major portion of the length of the bolt. One of the rails extends to the forward end of the bolt which, in the assembled rifle, is positioned inside the forward receiver ring adjacent the rear end of the barrel when the action is closed. The elongated rail cooperates with undercuts formed in the spaced lateral rails of the receiver to enable shells to be more smoothly and easily fed from the magazine to the chamber. The bolt is retained in its firing position by a plurality of locking lugs carried in the rear receiver ring which cooperate with the bolt rails. The bolt handle and bolt handle shroud are integrally formed and are a separate piece from the bolt proper which is screwed into the bolt handle shroud and pinned in this position.

Abstract: A burial facility comprising a rigid burial housing enclosing multiple burial crypts, burial services compartmentation, walk ways and facility maintenance spaces, said housing having a major portion thereof below ground level and a portion thereof above ground level, a frusto-pyramidal earthen mound covering and concealing the portion of said housing above ground level, and a downwardly sloping entryway extending through one side of said frusto-pyramidal earthen mound and communicating through an opening in one side of said housing with the interior thereof.

Abstract: Metallic copper is recovered from raw materials containing copper in a chemically bound state by first leaching the copper-containing raw material with a ferric chloride solution to extract copper as copper chloride in aqueous solution. The copper is extracted from the copper chloride solution with a liquid ion exchanger which is then stripped with sulfuric acid to form a copper sulfate solution. Metallic copper is recovered from the copper sulfate solution by hydrometallurgical reduction of it with hydrogen gas. An iron chloride salt may be crystallized from the copper-free raffinate from the ion exchange step, and then roasted to yield ferric oxide and hydrochloric acid. The hydrochloric acid produced in the roasting step is electrolyzed to produce hydrogen gas and chlorine gas which can be used in the regeneration of the ferric chloride leach solution.

Abstract: A vertically extending framework having a hydraulic ram subassembly mounted in the framework for pivotation about a horizontal axis, and spaced from the lower end of the framework to accommodate a refuse receptacle within the framework under the ram. A disinfectant injection pump is mounted in the hydraulic ram for automatically discharging a disinfectant into refuse compressed by the ram. The ram is double acting, and valve means is provided for automatically retracting the ram when a predetermined force opposes the outward extension of the piston of the ram.

Abstract: An illuminated fishing tackle box which includes an opened topped base portion of generally right parallelepiped configuration, a lid hingedly connected to one side of the base portion and forming a closure for the open top of the base portion, and a light swivelly mounted on one end of the base portion on the outside thereof for selectively directing a light beam in a direction extending toward the bottom side of, or alternately, directly out from, the base portion. A second light of different color from the first-mentioned light is mounted on the opposite end of the base portion from the first-mentioned light, electrical circuitry interconnects the two lights and includes means for causing the second mentioned light to undergo an intermittent on-off status so as to present a flashing light.

Abstract: A tubing bending machine is disclosed comprising a die and cooperating shoe means, means for advancing the die toward the shoe means to bend a pipe positioned therebetween, and a hydraulic piston and cylinder assembly coupled with the shoe means for restricting the movement of the shoe means during bending of the tubing, and for returning the shoe means to a pre-bending position. A linear scale is connected to a piston rod of the piston and cylinder assembly and movable therewith relative to the cylinder of the piston and cylinder assembly. A depth of bend indicator means is adjustably positionable along the linear scale to indicate a selected desired depth of bend reading thereon. Switch means is mounted on the machine in the path of movement of said depth of bend indicator means to be contacted by said depth of bend indicator means as it moves with said linear scale and piston rod of said piston and cylinder assembly during the bending of a tube.
