Abstract

The disclosure is directed to an apparatus and method for measuring the permeability of a gas in a sample. The gas is allowed to reach a steady flow rate through the sample. A measurable amount of the gas is collected during a given time period and then delivered to a sensitive quadrupole. The quadrupole signal, adjusted for background, is proportional to the amount of gas collected during the time period. The quadrupole can be calibrated with a standard helium leak. The gas can be deuterium and the sample can be polyvinyl alcohol.

Method for measuring radioactivities of tritium and /sup 14/C in sample air and apparatus for performing the same method

Patent Saito, T.; Watanabe, K.; Nishiyama, Y.; ...

An air sample including substances containing tritium and substances containing carbon-14 is oxidized continuously while measuring a volume thereof and water and carbon dioxide included in the oxidized air sample are collected respectively continuously. After water and carbon dioxide are recovered, the radioactivities thereof are measured respectively. 4 claims, 12 figures.
Method and apparatus for measuring rock permeability at elevated pressures and temperature

Patent Wiley, B.F.

The permeability of a rock formation is determined at elevated pressures and temperature by heating a core sample taken from the rock formation and a fluid which is utilized to determine the permeability of the core sample to an elevated temperature. The fluid is injected under pressure and a second pressure which is higher than the injection pressure is applied to the surface area of the core sample. The effect of injecting a fluid such as a corrosion inhibitor or a polymer useful in secondary or tertiary recovery techniques on the permeability of the rock formation can be determined atmore »« less

Patent Dissing, E.

A method of and an apparatus for human bone density determination in vivo. ..gamma..- or x-ray radiation of two different photon energies is scanned across the human body part to be examined. For the two photon energies, the logarithms of the intensities of the radiation transmitted through the human body part are determined simultaneously. The logarithm values obtained are processed on line such that the ratio of these values is changed by a predetermined factor. The processed values are subtracted from each other to produce a simultaneous output value which is integrated to give an examination result proportional to themore »« less
