    • A turbine meter for measuring the flow of a fluid comprises a housing having an inlet port and an outlet port and defining a fluid flow path along a central axis thereof. A flow conditioner is mounted in the flow path downstream of the inlet port and has a plurality of flow deflectors canted in a first direction relative to the central axis. A first turbine rotor is located downstream of the flow conditioner and is mounted for rotation about the central axis. The first turbine rotor has a plurality of first rotor vanes canted in a second direction relative to the central axis, the second direction being opposite to the first direction. The meter further comprises a second turbine rotor located downstream of the first turbine rotor and mounted for rotation about the central axis. The second turbine rotor has a plurality of second rotor vanes canted in the first direction relative to the central axis such that the first and second turbine rotors rotate in opposite rotational directions when fluid flows through the housing at rotational speeds indicative of fluid flow rate.
    • 用于测量流体流动的涡轮仪包括具有入口端口和出口端口并限定沿着其中心轴线的流体流动路径的壳体。 流动调节器安装在入口下游的流动路径中,并且具有相对于中心轴线在第一方向上倾斜的多个导流器。 第一涡轮转子位于流动调节器的下游,并且安装成围绕中心轴线旋转。 第一涡轮转子具有多个第一转子叶片,其相对于中心轴线在第二方向上倾斜,第二方向与第一方向相反。 该仪表还包括位于第一涡轮转子下游的第二涡轮机转子,并安装成围绕中心轴线旋转。 第二涡轮转子具有多个第二转子叶片,其相对于中心轴线在第一方向上倾斜,使得当流体以指示流体流速的转速流过壳体时,第一和第二涡轮转子沿相反的旋转方向旋转。

    • A self-contained and readily portable apparatus for at adjustably variable desired times dispensing desired amounts of liquid-spray or other material from containers such as pressurized aerosol cans, the apparatus including a drive motor and a driven linkage effective upon actuation and during each cycle of operation of the drive motor to momentarily depress the container''s spring-biased discharge valve. The frequency at which cycles of operation are instituted is adjustable and is controlled by a novel timer device including a clockworks mechanism having an hour hand output shaft upon which is mounted a disc element having on one surface a plurality of electrically conductive segments arranged in circular sets concentric with and at varying radial distances from the central axis of the disc, the circumferential spacing between the segments being equal within each set and different from set to set. An electric contact is mounted for adjustment radially of the disc surface so as to overlie any desired set of conductive segments thereon, and so as to sequentially and periodically engage the segments of such set during disc rotation. Engagement between the contact and a conductive segment completes a circuit including the drive motor and its power source, which comprises a battery pack from which the clockworks mechanism is also energized, instituting a cycle of operation. The cycle is terminated by engagement between a switch element in the circuit and a cam member of the motordriven linkage. Intermediate successive cycles of operation, a second contact engaging the disc surface actuates the motor momentarily to disengage the cam member and the switch.
