Abstract: The present invention relates to a method and apparatus for obtaining measurements of induced resistivity of objects from confined spaces such as within the confined space of a down-hole hydrocarbon production well. It is well known that measuring the resistivity of an object or media can provide useful information regarding the composition and the location of object or media. The present invention utilizes the principles of Magnetic Antenna™ and Magnetic Lensing™ to obtain information regarding the location and properties of the target object.

Abstract: A method and apparatus for transmitting electromagnetic flux through well casing or similar materials to measure or detect the electrical resistivity of media in the surrounding geologic formation. The invention creates a magnetically transparent region in an electromagnetic barrier material, e.g., ferromagnetic metal well casing. It further incorporates a transmitter sending an electromagnetic wave at a selected frequency and strength, and a receiver to measure returning signals. The method and apparatus may also incorporate the controlled use of electromagnetic barrier material that can be wholly or partially saturated with electromagnetic energy in order that the electromagnetic wave transmitted by the invention can be focused in a controlled manner.

Abstract: An apparatus for the detection and identification of metal particles, coolant or water in engine oil or hydraulic fluid. The apparatus comprising means for generating a high frequency oscillating field within the fluid, means for generating an electric field within the fluid, means for measuring the real and imaginary part of the complex impedance associated with the interaction of the electric field and the fluid, and means for determining at least one of the presence, the absence or the variation of metal particles, coolant or water in the fluid based upon the impedance measured. The high frequency oscillating field has a frequency range of approximately 2 megahertz to 10 gigahertz. Also, apparatus for the detection and characteristic identification of contaminants in engine oil or hydraulic fluid is provided.

Abstract: A method of separating the constituents of a fluid where the constituents have different physical characteristics including mass, weight, coefficient of friction and the like. The method comprising impeding the flow of the fluid for causing the fluid to move in a curvilinear path. By moving in a curvilinear path, the fluid is effected by centrifugal forces. The centrifugal forces cause the separation of the constituents of the fluid. Further, the effected fluid is slowed for further enhancing separation of the constituents of the fluid.
