    摘要： A multiple well tissue culture plate (10) having a plurality of opened bottomed wells (36) with a semi-permeable membrane (20) across the bottoms of a plurality of such wells (36). The multiple well tissue culture plate (10) is placed in contact with the basal medium (26) contained within the basal medium reservoir (12) to allow for exchange of nutrients and waste products between the basal medium (26) and the culture medium (22) across the semi-permeable membrane (20). The dialyzed multiple well tissue culture plate (50) provides dialysis of each individual well within the multiple well tissue culture plate (10) thus eliminating traditional exchange of culture medium to maintain proper culture conditions.

    摘要： A pressure control system for a bioreactor of the type having a gas space and a cell culture space therein is supplied with a gas such as oxygen separately from the supply of liquid nutrient media. The pressures in the gas space and the pressure in the cell culture space are controlled so that a higher pressure is maintained in the cell culture space than in the gas space to prevent displacement of the liquid nutrient media.

    摘要： A sensor-activated, battery-powered toilet room flush valve has a body with an inlet and an outlet. There is a valve seat in the body and a diaphragm which closes upon the seat to control flow between the inlet and the outlet. A cover mounted on the body defines a pressure chamber with the diaphragm and there are a sensor, solenoid and battery mounted on the cover and connected for operation of the flush valve. There is a passage in the cover connecting the pressure chamber and the outlet. Operation of the solenoid opens the passage to relieve pressure in the chamber to the outlet whereby the diaphragm moves off its seat to open communication between the inlet and outlet. A stop is positioned within the chamber and attached to the diaphragm to limit its movement toward the cover, which in turn controls the volume of water passing through the flush valve prior to closure of the diaphragm upon its valve seat. The stop is adjustable from the outlet side of the valve.

    摘要翻译： 传感器启动的电池供电的厕所冲洗阀具有带入口和出口的主体。 主体中有一个阀座，一个隔膜在阀座上关闭，以控制入口和出口之间的流动。 安装在本体上的盖子限定了具有隔膜的压力室，并且安装在盖上并连接以用于冲洗阀的操作的传感器，螺线管和电池。 在连接压力室和出口的盖子中有一个通道。 螺线管的操作打开通道以将腔室中的压力释放到出口，由此隔膜从其座部移开以打开入口和出口之间的连通。 止动件定位在腔室内并且附接到隔膜以限制其朝向盖的运动，其又在隔膜在其阀座上闭合之前进而控制通过冲洗阀的水的体积。 止回阀可从阀门出口侧调节。

    摘要： An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is peripendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maxium time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry. Any incremental interruption in the reflected signal which does not exceed the period of permitted interruption, restarts the commencement of the timing of the maximum period of continuous detection.

    摘要翻译： 自动干手器包含一个加热元件和一个驱动松鼠笼风扇的马达。 风扇将空气通过加热元件排出到向下的出口。 基座或安装板适于嵌入安装在墙壁上。 风扇的轴线垂直于干燥器所连接的基板和墙壁。 控制或感测电路将信号发射到出口下方的检测区域，并监视该区域以反映出用户的存在的反射信号。 该电路用于为风扇电机和加热元件通电和断电。 当检测到预定时间时，电路使电源电路通电。 控制电路在反射信号中断一段预定时间之后，或在连续检测的预定最大时间周期之后，使电源电路断电。 在后一种情况下，反射发射信号的刺激必须从检测区域移除，以重新激活控制电路。 反射信号的任何增量中断不超过允许中断的周期，重新开始连续检测的最大周期的定时。

    摘要： A faucet for automatic operation defining a base and an elongated cantilvered spout body provided with a discharge outlet. A sensing means for automatic operation in the form of an emitter and detector are mounted on the spout body intermediate the base and discharge outlet. The emitter and detector are positioned on the longitudinal center of the spout body and provide a concentrated zone of effective detection disposed intermediate the area of discharge from the faucet and the base. The zone shape is transversely elongated relative to the longitudinal center of the faucet spout body.
