摘要： An air valve actuated by an electric motor has a cylindrical inlet section. The inlet section defines a seating surface upstream of which is a support grid. A backplate to which the actuating motor is mounted is supported by a plurality of rods that extend downstream of the inlet section. A damper assembly includes a generally planar damper mounted for movement axial of the inlet section. The damper assembly includes a splined rod which extends upstream of the damper and into a cooperating spline in the support grid. A threaded spindle extends downstream of the damper plate through a cooperatively threaded motor-driven drive gear which is mounted for rotation on the backplate. Because a portion of the damper assembly is splined, the damper assembly cannot rotate and is driven axially within the valve by the rotation of the drive motor and drive gear. The backplate is spring biased so that upon the abutment of the damper plate with the inlet section seating surface the backplate becomes spring loaded in a manner which minimizes the chance that the drive motor will stall.
摘要翻译：由电动机驱动的空气阀具有圆柱形入口部分。入口部分限定了一个座面，其上游是支撑格栅。安装有致动马达的背板由在入口部分的下游延伸的多个杆支撑。阻尼器组件包括安装成用于在入口部分轴向运动的大致平面的阻尼器。阻尼器组件包括花键杆，其在阻尼器的上游延伸并且进入支撑格栅中的配合花键。螺纹主轴通过协作螺纹的电机驱动的驱动齿轮延伸到阻尼板的下游，该驱动齿轮安装成用于在背板上旋转。因为阻尼器组件的一部分是花键的，所以阻尼器组件不能旋转并且通过驱动马达和驱动齿轮的旋转在阀内轴向地被驱动。背板是弹簧偏置的，使得当阻尼板与入口部分座表面邻接时，背板变成弹簧加载的方式使得驱动马达将失速的机会最小化。

摘要： A normally closed pneumatically actuated air valve for use in a variable air volume air distribution system has a unitary inlet section which supports a damper assembly and actuator through a support grid disposed in the inlet section. The damper assembly is mounted for axial movement, on a fixed spindle and guide piston, under the impetus of the expansion of a pressure chamber defined by a portion of the damper assembly and a diaphragm which conformably surrounds the guide piston. A biasing spring acts on a surface of the fixed guide piston and on the damper assembly to bias the damper assembly toward a seating surface of the inlet section.

摘要： A normally open pneumatic air control valve includes an inlet section which defines a seating surface and a support grid. A support plate, located downstream of the inlet section, is itself supported by a plurality of rods extending from the inlet section. A damper assembly is disposed for movement axial of the inlet section and is supported for such movement between the inlet section support grid and the downstream support plate. The damper assembly is actuated by the admission of a pressurized gas to a chamber cooperatively defined by a housing fixed to the support plate and a diaphragm disposed therein. A spring acts on the fixed grid support of the inlet section and on the damper assembly to urge the damper assembly away from the inlet section so that the valve is biased to the open position.

摘要： Bias recording is used to record servo patterns on magnetic tape. With use of bias recording, a faster recording process may be provided relative to conventional pulse recording processes. A servo pattern recording method includes providing a servo band along at least a portion of a length of a tape. Bursts of a first signal are recorded in a first servo track of the servo band along the length of the tape and a second signal, e.g., a continuous signal, is recorded in at least a second servo track of the servo band along the length of the tape. The second servo track is recorded adjacent to the first servo track and at least one of the first signal and the second signal is recorded using a bias signal at a bias frequency summed with a record signal at a record frequency. A system for carrying out the bias recording of servo patterns is also described.
