摘要： A method and apparatus are disclosed for determining the concentration of coliform bacteria in a sample. The sample containing the coliform bacteria is cultured in a liquid growth medium. The cultured bacteria produce hydrogen and the hydrogen is vented to a second cell containing a buffer solution in which the hydrogen dissolves. By measuring the potential change in the buffer solution caused by the hydrogen, as a function of time, the initial concentration of bacteria in the sample is determined. Alternatively, the potential change in the buffer solution can be compared with the potential change in the liquid growth medium to verify that the potential change in the liquid growth medium is produced primarily by the hydrogen gas produced by the coliform bacteria.

摘要： Galvanized steel stock treated for the application of a finished coating or top coating. The galvanized steel is roughened with zinc pellets. The use of zinc pellets ensures that there are essentially no impurities in the treated zinc coating which would later form oxidation sites for corrosion.

摘要： A multi-point fluid sample collection and distribution system is provided wherein the sample inputs are made through one or more of a plurality of sampling valves to a progressive cavity pump which is not susceptible to damage by large unfiltered particles. The pump output is through a filter unit that can provide a filtered multi-point sample. An unfiltered multi-point sample is also provided. An effluent sample can be taken and applied to a second progressive cavity pump for pumping to a filter unit that can provide one or more filtered effluent samples. The second pump can also provide an unfiltered effluent sample. Means are provided to periodically back flush each filter unit without shutting off the whole system.
摘要翻译：提供了多点流体样品收集和分配系统，其中样品输入通过多个采样阀中的一个或多个进行到渐进式空腔泵制造，其不易受大的未过滤颗粒的损坏。泵输出通过可以提供过滤的多点样品的过滤器单元。还提供了未过滤的多点样品。可以取出流出物样品并将其施加到第二渐进腔泵，以泵送到可以提供一个或多个过滤的流出物样品的过滤器单元。第二泵还可以提供未过滤的流出物样品。提供装置以周期性地反向冲洗每个过滤器单元而不关闭整个系统。

摘要： A radial bellcrank actuator comprising a piston with a circumferential piston groove, and a bellcrank attached to an output shaft. The bellcrank has a bellcrank piston lobe at one end, and a bellcrank output shaft lobe at the other. The bellcrank piston lobe is attached to the bellcrank output shaft lobe at a bellcrank waist. The bellcrank piston lobe is sized to fit into the piston groove, such that reciprocation of the piston causes rotation of the bellcrank and attached output shaft. Relationships between the dimensions of the bellcrank lobes, the distance between their centers, the thickness of the bellcrank piston lobe, and the waist width are disclosed, which permit the preferred embodiment radial bellcrank actuator to provide up to 90 degrees of rotation. Thus, the instant invention is economical, simple, long-lasting and provides symmetrical loading to its components.
