摘要： An internal gate rotary vane fluid meter which has markedly improved performance as a result of precise control over the geometry and dimensions of the rotating elements and the fluid flow path. In particular, the outer diameter of the gate is the maximum possible which still allows the crescent to have an arc about the rotor axis which is sufficient to enclose the radial center lines of any adjacent pair of rotor vanes.

摘要： A downdraft exhaust cutting table comprising an elongated cutting table having a cutting torch positioned thereover and which is movable along the length thereof to cut material positioned on the cutting table. An elongated exhaust duct is positioned beneath the cutting table and runs parallel to the length of the cutting table. The exhaust duct has a plurality of horizontally spaced-apart exhaust openings formed therein which close by a movable damper. In one embodiment, successive dampers are opened as a slag collection bucket moves along the length of the cutting table below the cutting torch. In a second embodiment, a plurality of ventilation zones are created by pivotal gates extending laterally outwardly from the exhaust duct and which are pivotally movable to permit slagger to pass therethrough.

摘要： An arrangement for determining the supercompressibility factor of a flowing gas at elevated pressure includes a first meter for measuring the volume flow rate of the gas at the elevated pressure, a restrictor at the outlet of the first meter for dropping the pressure of the gas to a pressure at which the supercompressibility factor is known, and a second meter for measuring the volume flow rate of the gas at the lower pressure. A computer calculates the supercompressibility factor of the gas at the elevated pressure by utilizing measured values of temperature, pressure and volume flow rate of the gas at both the elevated and lower pressures.

摘要： A gas flow volume corrector mounted on a flow meter is provided with a microprocessor which calculates a corrected volume each time the meter measures a unit volume of flowing gas. Customer supplied data as to base conditions, specific gravity and gas composition are utilized to calculate supercompressibility values. These values are then processed to provide a plurality of constants which define calculation equations. The constants are stored in the corrector on a diode matrix card or PROM and are utilized each time the meter measures a unit volume of flowing gas for calculating the corrected volume. To conserve memory space, integer arithmetic, rather than floating point arithmetic, is utilized in the calculations.
摘要翻译：安装在流量计上的气体流量校正器设置有微处理器，每当计量器测量流动气体的单位体积时，计算校正体积。客户提供的基础条件数据，比重和气体成分用于计算超压缩值。然后处理这些值以提供定义计算方程的多个常数。这些常数存储在二极管矩阵卡或PROM上的校正器中，每当仪器测量单位体积的流动气体以计算校正后的体积时，就会使用这些常数。为了节省存储空间，在计算中使用整数运算而不是浮点运算。
