    摘要： A chromatography column and method of maintenance is described which does not require the use of a hoist or crane for disassembly. The method provides improved operator safety by reducing the need for the operator to work below a suspended or supported load within the column. Furthermore, the removal or replacement of column components is facilitated by providing access to the interior of the column and by the provision of a handling device.

    摘要： Apparatus and method for monitoring the wear of a downhole tool, and providing indication of the degree of wear to an operator at the well surface. Rotating torque can exhibit a drop when wear of the cutting element matrix progresses to wear pads within the matrix. Other wear indicators can also be built into the cutting element matrix. Progression of wear down to the indicator can be directly measured at the well surface, or relayed to the surface via a downhole communication system.

    摘要： A monolithic sheet metal chord nailing restricting and web stiffening device features a chord plate combined with a web stiffening structure configured for lateral attachment to the web of a wooden I-joist. The chord plate is positioned on the bottom of the web stiffening structure and features a nail restricting hole having a diameter that corresponds to a predetermined diameter of a chord nail as defined by wooden I-joist manufacturers. The web stiffening structure has a web plate for attachment to the web and a buckling opposing web stiffening rib. Once the web stiffening structure is attached to the web above the bearing rest the nail restricting hole restricts chord nailing position and nail shaft diameter to manufacturer defined limits. Two devices may be combined by a web front bridge plate for simultaneous attachment of two opposite devices along an I-joist end.

    摘要： A circuit and a method for writing a binary value to a memory cell are provided. The circuit includes a first field-effect transistor having a first drain, a first drain, and a first gate operably coupled between the first drain and the first source. The first drain is operably coupled to a first memory cell. The first gate configured to receive a first data signal. The circuit further includes a second field-effect transistor having a second drain, a second source, and a second gate operably coupled between the second drain and the second source. The drain source is operably coupled to the first memory cell. The second gate is configured to receive a second data signal. The circuit further includes a first signal inverter having a first input terminal and a first output terminal. The first output terminal is operably coupled to both of the first and second sources. The first signal inverter is configured to output a first control signal on the first output terminal when the first input terminal receives a second control signal. When the first control signal has a second logic level and the first data signal has a first logic level and the second data signal has the second logic level, the first and second field-effect transistors induce the first memory cell to store a first binary value.
