    • A travel sensor (10) is proposed which has a insertion body (11) consisting of non-ferromagnetic material with good conductive properties. The insertion body (11) is submerged into a measuring coil (15) through which alternating current flows. In addition, the travel sensor is enveloped by a shielding sleeve (16) consisting of ferromagnetic material. Due to the alternating effect between the magnetic field of the coil (15), through which an alternating current flows, and the two materials, at designated frequencies of the alternating current and the respective volume of the insertion body (11) or the shielding sleeve (16), it is possible to compensate the effects of the temperature in such a way that at varying temperatures the measuring curves of the travel sensor (10) extend nearly parallel across the entire measuring range.

    • A diffuser for introducing gas in bubbles into liquid held in an aeration tank comprising a body member having a backing surface and passaging extending from a gas inlet to an outlet at the backing surface, and a flexible, gas permeable membrane covering the backing surface and secured at its periphery to the body member in sealing relationship thereto. The membrane is adapted to distend and move away from the backing surface upon delivery of gas under pressure to diffuser, with the gas flowing through the distended portion of the membrane and into the liquid in the form of relatively small gas bubbles, and adapted to collapse into engagement with the backing surface when gas under pressure is not delivered to the diffuser. A check valve comprising a movable valve member on the membrane and a valve seat on the backing surface enables flow of gas into the space between backing surface and the membrane, and blocks flow of liquid into the passaging in the body member.
    • 用于将气泡气体引入保持在曝气池中的液体的扩散器,其包括具有背衬表面的本体构件和从气体入口延伸到背衬表面处的出口的通道,以及覆盖背衬表面的柔性透气膜, 在其周围与本体构件密封的关系。 当气体在压力下将气体输送到扩散器时,膜适于膨胀并远离背衬表面,气体以较小气泡的形式流过膜的膨胀部分并进入液体中,并适于塌缩 当压力下的气体不被输送到扩散器时,与背衬表面接合。 包括膜上的可移动阀构件和背衬表面上的阀座的止回阀使得气体能够流入背衬表面和膜之间的空间中,并阻止液体流入主体构件中的通过。
