Abstract: The resistance of a cable conductor between a measuring point and a conductive fault is measured using an electronically regulated current source and a very high resistance voltmeter in such a way as to eliminate contact and fault resistance as a source of error. Distance to the fault is determined by calculation from the known resistance per unit length.
Abstract: A cleaner for cleaning from hands and the like difficultly removable objectionable material such as modern catalyzed auto paint, fast drying printers ink and the like characterized by a multi-component composition that includes at twenty-five percent by weight and no more than sixty percent by weight of dibasic ester consisting essentially of an admixture of dimethyl succinate, dimethyl glutarate and dimethyl adipate; at least five percent by weight and no more than twenty-five percent by weight of dipropylene glycol methyl ether; at least five percent by weight and no more than twenty-five percent by weight of oderless mineral spirits; at least four percent and no more than nine percent by weight of triethanolamine; at leat five percent and no more than fifteen percent by weight of octylphenoxypolyethoxyethanol in which there are seven to eight moles ethylene oxide per mole of octyl phenol; at least one percent and no more than three percent by weight of nonyl phenol ethoxylate having about four moles of eth
Abstract: What is disclosed is a method of forming a high-strength proppant that resists the deleterious effects of high temperature saline environments characterized by the steps of forming a plurality of particles of propping agent; and coating particles with a thin high-strength covering in a fluidized bed employing chemical vapor deposition to deposit a coating substantially uniformly over all the exposed surfaces of the particles to increase durability of the particles, as well as their strength and resistance to the deleterious effects of hot saline environment. Preferably, each particle has at least one passageway formed directly therethrough for increased permeability once deposited.
Abstract: There is disclosed an extension apparatus for a damper assembly having an extension member for effectively extending the damper assembly control shaft and a securing member for securing the extension member onto the control shaft.
Abstract: An improvement in a subsea wellhead apparatus that includes the conventional plurality of strings of conduit suspended in a borehole penetrating subterranean formations below the bottom of a sea at which the wellhead apparatus will be placed and the conventional wellhead and accessories disposed above the bottom and the plurality of strings of conduit; the improvement comprising a first communications aperture communicating with a first annular space intermediate a desired pair of conduit strings; a sealed conduit that defines a sealed path of flow for flowing a fluid waste into the annulus intermediate the respective conduit strings; remotely operable high pressure control valves interposed in the conduit for controlling the flow of fluid between the annular spaces and a remote control for controlling the flow control valves so as to route the fluid waste to the first annular space and fractured formation communicating therewith.
Abstract: An improvement in a knee brace for alleviating problems with tibia rotation, subluxation and migration with respect to a femur of a wearer, including conventional first and second pairs of elongate braces having their respective hinges connected at their central ends, characterized by the improvement in the form of a plurality of 8 flexible, inelastic, non-metallic bands connected at the plurality of points of fixation anteriorly and posteriorly of the respective braces for tightening to fit any leg and lie close to the leg. In a preferred embodiment, the respective plurality of straps connected to their respective D-rings anteriorly and posteriorly of the braces include a de-rotation pad for being held tightly adjacent the tibia at the inside anterior of the tibia to prevent rotation of the tibia.
