Patent CA-2258365-A1 (CA)
Inventor: LAYTON KENNETH R
IPC: E21B21/06
Filed: 1999-01-11
Abstract: Apparatus and a process are provided for treating used drilling mud, particularly that produced during clearwater drilling. A structural and highway transportable skid comprises two or more settling tanks connected in succession. Flocculation aids settling of solids to the bottom and clarified liquid forms at the surface. Clarified liquid flows from one tank to the next successive tank. Clarified liquid is produced from the last of the successive settling tanks. The tanks have flat bottoms. Passageways extend between each successive tank for gravity-flowing liquid from one tank to successive settling tank. A solids tank is also mounted within the skid. The solids and settling tanks are located for weight-balancing. A rotational suction is positioned in the bottom of each settling tank and having one or more radially extending conduits which rotate about an axis and have inlets at their distal ends which traverse an inscribed circular path about the periphery of the tank's bottom. Collected solids are directed to the solids tank and a drag conveyor transporting solids product outside the skid. 37

Abstract: A lithium secondary battery uses an organic electrolyte solution and includes a battery case, an internal electrode body contained in a battery case and including a positive electrode, a negative electrode and a separator made of porous polymer. The positive electrode and the negative electrode are wound or laminated so that the positive electrode and negative electrode are not brought into direct contact with each other via the separator. A zeolite having a moisture absorption characteristic, has been incorporated in the battery case so that the zeolite is brought into contact with the organic electrolyte solution within the battery case. The lithium secondary battery achieves suppression of deterioration of a charge-discharge cycle characteristic of a battery caused by decomposition of an electrolyte by limiting moisture mixed into an organic electrolyte solution to a considerably lower level as well as improvement of its self-discharge characteristic.

Title: Apparatus suitable for searching objects in water
Inventor: SEKINE CHOGO
IPC: G01S7/62
Filed: 1999-03-25
Abstract: A fish finder having two 1D transducer arrays vertically arranged on a ship's hull. Each 1D transducer array provides a beam having a narrow width on a plane parallel to a plane in the transducer arrangement direction, and a fan-like beam on a plane crossing the plane. Ultrasonics are transmitted toward and received from the target on the first plane, by using the fan beam of the first 1D transducer array, and received from the second plane perpendicular to the first plane by using the fan beam of the second 1D transducer array. While the beam direction of the first 1D transducer array is gradually changed, that of the second 1D transducer array is rapidly changed so that information concerning the 3D space below the water surface is obtained. The obtained information is subjected to ray tracing processing for 3D displaying of an image on a 2D screen. This arrangement enables quicker detection of fish schools.

Title: Apparatus and method for detecting and characterizing signals in a communication system
Inventor: ANANTHAIYER SATISH
IPC: G10L25/90
Filed: 1998-11-13
Abstract: An apparatus and method for detecting and characterizing signals in a communication system provides efficient voice, tone, and noise detection which reduces the amount of processing resources consumed and also distributes the processing demand over time. The present invention provides for such efficient voice (412), tone (414), and noise (410) detection by applying the Average Magnitude Difference Function (404) over discrete time intervals to evaluate variations in pitch over time, allowing a hypothesis (402) to be made as to whether a signal is a voice, tone, or noise signal. Two novel metrics are computed which characterize the signal as to pitch and variation in pitch. Rule-based logic is applied to detect transitions between the types of signals.
