摘要： A method and apparatus for simultaneously generating spatial profiles of moisture, thickness, and basis weight across a moving web of paper in a paper making machine. The apparatus includes a plurality of means for generating first and second beams of coherent microwave radiation and for generating signals proportional to the intensity of radiation applied to, reflected from, and transmitted through the web. The incident, reflectance, and transmittance signals for the two frequencies are used to solve simultaneous equations to generate moisture, thickness, and basis weight values at various positions across the web.

摘要： Disclosed is an effective dilution apparatus of simple construction which is easy to manufacture and use. The sample liquid is passed through a non-wetting porous membrane from a reservoir of sample liquid to a flowing stream of diluent which is constantly flowing when the sample liquid penetrates the membrane under positive pressure differential from the sample side of the membrane. The pressure differential can be suitably obtained both by means for exerting pressure on the sample liquids as for example on a stream of sample liquid on the entry side of the membrane as well as a reduction in pressure on the exit side of the membrane. The passage of the sample liquid through the non-wetting porous membrane requires a minimum liquid entry pressure differential across the membrane to cause penetration through the pores and not the material.

摘要： APPARATUS AND METHOD FOR ANALYSIS OF LIQUID SAMPLES A fluid injection analysis apparatus (10) and method has a liquid stream (13) and a detector (12) and a computer (11) which operates to observe properties in the composition of the fluid stream and compare detected data from observed samples with standards and in accordance with parameters established by calibration calculate the characteristics of the observed samples. An integral but segmented liquid stream (13) flows through the analysis system (10) to provide liquid segments of observed sample and reagent. A detector (12) scans data from the samples at the interface between these segments and information relating to the composition at the interface is analyzed by a mathematical model that permits comparison of the detected data from successively observed samples with standards and thus determines the characteristics of the samples. The information includes values such as electrical conductivity, concentrations, and compositions of the samples and the operation rapidly and precisely analyzes and records multiple samples. The segmented integral liquid stream (13) is fashioned by step pulsing of discrete segments of reagents and samples and transporting the discrete segments to a detector (12). The analysis system (10) is driven by a vacuum assembly (16) and valves (23a, 28b, 28c, 28d and 36) are opened to draw samples and reagents into tubing (14) and form the segments in the absence of air so that the respective sample and reagent segments interface with each other. A plurality of source tanks (20) provide the liquid samples and reagents for the segmented, integral liquid stream (13) and the vacuum assembly (16) creates a force which forms and drives the samples and reagents through conduit means (21), (23), (27), (14) and 138) to the detector (12). The detector (12) is positioned between the source tanks (20) and the vacuum assembly 16 so that stream (13) is passed through the detector (12) to the vacuum assembly (16).
