Abstract: A method for the measurement of electrical properties of materials through non-magnetizable materials. The method also to calculate the thickness of a material with unknown permeability and conductivity using transparencies. The method comprising the steps of creating a first set of electromagnetic waves having specific constant amplitude of a known frequency, the first set of electromagnetic waves for engaging a system, impinging the first set of electromagnetic waves on the system under investigation, nulling the system, receiving a nulled signal, creating a change in the system, and receiving a modified signal associated with the change from the nulled signal such that the modified signal contains sufficient information to determine the change in the system.

Abstract: There are many liquid flows in which the concentration and content of the materials within the flow change or vary. One important example is the varying percentage of water found in a liquid hydrocarbon, e.g., crude oil. It is desired to detect and measure the variations in the concentration of water contained in a hydrocarbon being removed from a hydrocarbon production well. It is also important to detect changes in the salinity of the water and to production well.

Abstract: The present invention relates to a method and apparatus for obtaining measurements of induced resistivity of objects from spaces such as within a down-hole hydrocarbon production well. The invention also relates to measuring the location or direction of objects based upon measured responses from objects engaged or impinges by one or more transmitted signals having different phase and directional orientation. The invention relates to generating at least one signal or wave and transmitting it through a plurality of different materials that may have varying properties of density, magnetic permeability and dielectric that may each emit a separate signal with altered phase and directional orientation. When used with electromagnetic signals, the resistivity of an object or media can provide useful information regarding the composition and the location of object or media.

Abstract: A method is provided for creating a spectral EM frequency to calculate the thickness of a material with unknown permeability and conductivity using metallic transparencies. The method comprises the steps of testing empirically to approximate the conductivity, testing empirically to approximate the permeability, creating a first set of electromagnetic waves adjacent to the material to be measured of a relatively low frequency, impinging the first set of electromagnetic waves on the material for saturating the material, creating a second set of electromagnetic waves having specific constant amplitude of a higher frequency than the first set of electromagnetic waves, the second set of electromagnetic waves for engaging the material and generating a sensing signal having modified characteristics, and receiving the sensing signal through the saturated material such that the modified characteristics of the sensing signal are processed to determine the thickness of the material.

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 loading spout hoist mechanism comprises a multiple monospiral winch drum. The drum is located under the top of the loading spout, and the loading spout passes through it. The multiple monospiral winch drum is supported on two rings, the first of which is located inside the second. The first ring is fixed to the loading spout support frame, and the second ring is journalled to first one. The second ring also carries a ring gear, which may comprise gear teeth machined into the ring, or a separate ring gear attached to the second ring. The loading spout support frame carries a pinion drive mechanism which engages the ring gear, and can rotate the second ring in either direction, to raise and to lower the loading spout by winding in or out the loading spout support cables carried in each monospiral of the winch drum. In a modification, the loading spout is attached to the support frame by motorised pin mechanisms.
