摘要： An underdrain flume plate for use in a filter including at least one central opening having an upstanding flange to interface with a cut-out in an underdrain lateral to form a passageway for connecting the lateral to the flume. The flume plate may also include at least one raised channel at each end of the plate with a solid or cut-away top surface, and/or holes and/or slots for connection of the flume plate to anchor rods and may be configured to overlap one another when placed side by side. The present invention also includes a method of installing underdrain laterals in a filter, including arranging a grid of anchor rods on a filter floor such that anchor rods are provided on both sides of the flume, and providing at least one underdrain flume plate adapted for attachment to the anchor rods such that the flume plate covers the flume.

摘要： A gas detection device is provided comprising an exterior housing in which an active pelement and a compensating pelement are disposed. The gas detection device further comprises a porous frit seated within a distal end of the exterior housing to separate the active pelement and the compensating pelement from the surrounding environment. The porous frit is adapted to prevent flashback into the surrounding environment while allowing movement of environmental gas through the porous frit to contact the active pelement and the compensating pelement. The gas detection device further comprises a flow guide for directing flow of environmental gas into the gas detection device disposed adjacent the exterior side of the porous frit. The flow guide comprises an inlet port through which a forced flow of environmental gas is pumped to pass through the porous frit and into the exterior housing in a direction generally parallel to the axis of the exterior housing. The flow guide also comprises an outlet port through which gas may exit the exterior housing. A gas detection device is also provided in which the electrical resistance of the compensating pelement is measured to determine concentration of combustible gas at combustible gas concentration levels above a predetermined concentration level set equal to the LEL (Lower Explosive Limit). The gas detection comprises a circuit for reducing current passing through the active pelement when the gas detection device is being used above the predetermined concentration level.
摘要翻译： 提供了一种气体检测装置，其包括外部壳体，其中设置有活动毛发和补偿毛发。 气体检测装置还包括位于外部壳体的远端内的多孔玻璃料，以将活动砂浆和补偿颗粒与周围环境分离。 多孔玻璃料适于防止回流到周围环境中，同时允许环境气体通过多孔玻璃料移动以接触活性孔和补偿层。 气体检测装置还包括用于将环境气体流引导到邻近多孔玻璃料的外侧设置的气体检测装置中的流动引导件。 流动引导件包括入口端口，通过该入口泵送环境气体的强制流通过多孔玻璃料并沿大致平行于外部壳体的轴线的方向进入外部壳体。 流动引导件还包括出口，气体可以通过该出口离开外部壳体。 还提供一种气体检测装置，其中测量补偿孔的电阻以确定可燃气体浓度水平之上的可燃气体的浓度高于设定为等于LEL（较低爆炸极限）的预定浓度水平。 当气体检测装置被使用高于预定浓度水平时，气体检测器包括用于减少通过活性孔的电流的电路。

摘要： A personal sampling apparatus having multiple sampling ports for simultaneously taking a plurality of ambient air samples in parallel. Incorporated into the sampling apparatus is a regulator for enabling the apparatus to function with virtually any personal sampling pump. The regulator by being located immediately proximate to the sampling ports is able to provide independent vacuum flow rate control of each of the multiple sampling ports.

摘要： An underdrain block including a top wall, a bottom wall, and a pair of sidewalls defining a hollow interior and having a longitudinal axis, wherein the sidewalls, top wall, or both comprise at least one external detail. A handle is detachably connected to the external detail for transportation and positioning of said underdrain block. The external detail may comprise one of a protrusion or a receptacle for receiving a protrusion and the handle may include the other of a protrusion or a receptacle for receiving a protrusion. Also, a method of installing an underdrain block lateral comprising at least one underdrain block including the steps of attaching a handle to external details on the underdrain block, lifting the underdrain block lateral by the handle, positioning the underdrain block lateral into the underdrain system, and detaching the handle from the external details of the underdrain block.
