Abstract: The present invention relates to a quantitative evaluation method for concrete workability based on bottom resistance, including the following steps: step 1, carrying out a test for bottom resistance of fresh concrete; step 2, drawing a curve of inserting velocity of steel sheet over time; and step 3, quantitatively evaluating a concrete workability based on conditions of the bottom resistance. This method can quantitatively characterize the sinking condition of aggregate of the fresh concrete by effectively carrying out the test for bottom resistance of fresh concrete, calculating the inserting velocity of concrete and drawing the curves of displacement and velocity over time, so as to achieve the quantitative evaluation for concrete workability and overcome the defects of conventional methods that it is difficult to quantitatively characterize the segregation degree of concrete.

Abstract: Method and system is described to enhance operations for managing the hydrocarbon release. The system utilizes an airborne detection device equipped with measurement components and communication components. The system may utilize various measurement techniques to determine the thickness of the oil slick. This remote detection method may provide a dedicated airborne detection device for each response vessel and that can identify the location and thickness of the oil slick.

Abstract: A method and apparatus using sample test container filled with beverage, a penetrator holder, a penetrator and release means is disclosed. In the method a sample, is drawn into the test container and the penetrator dropped into the sample, and a reading of the stiffness of the sample is made based on the depth of penetration of the penetrator onto the sample.

Abstract: Methods and systems for characterizing drilling fluids laden with LCM (Lost Circulation Material) and other solid materials are disclosed. A test cell for analyzing a fluid is provided with a first conical inner portion and an axial positioning device positioned along an axis of the test cell. A first conical plug is coupled to the axial positioning device and is movable in and out of the first conical inner portion along the axis of the test cell. A fluid inlet is positioned at a first location on the test cell and a fluid outlet at a second location.

Abstract: A method is for connecting a tab pattern formed on a base sheet and a lead wire, wherein the tab pattern includes: a tab main portion; and a connecting portion formed to continue from one edge line of the tab main portion and to extend from the tab main portion along an extension line that is substantially orthogonal to the edge line, and wherein the method includes: connecting the lead wire on the tab main portion by bonding the lead wire at a position being displaced from the extension line of the connecting portion for more than a given offset amount where the extension line is identical to a center line of the connecting portion, the position being within a given distance from the edge line of the tab main portion.

Abstract: An apparatus for measuring the viscosity of a fluid is provided. The apparatus includes a vessel for containing a supply of the fluid and a member. The member is positionable within the vessel for displacement within the fluid. The apparatus also includes a measuring mechanism connected to the member and operably associated with the vessel for measuring the force required to displace the member within the fluid. The measuring mechanism is adapted to measure the force required to displace the member within the fluid. The force is indicative of the viscosity of the fluid.

Abstract: A device for measuring the elastic-viscous properties of objects, in particular objects made of an elastomer material such as rubber, has a measurement body movable in relation to a holder and having a measurement head that can be set on a test object, means for moving the measurement body back and forth and means for measuring the path of displacement of the measurement head and/or the force that acts on the measurement head during the reciprocating movement of the measurement body. In order to diversify the possible uses of the device and to simplify the measurement process, the measurement body is mounted in a freely movable housing with a passage for the measurement head and a bearing surface that can be set on the test object.
