Abstract: There is provided a novel method of testing for the presence of an analyte in a fluid suspected of containing the same. In this method, in the presence of the analyte, a substance capable of modifying certain characteristics of the substrate is bound to the substrate and the change in these qualities is measured.

Abstract: A measurement while drilling nuclear tool adapted to be coupled in the drill string to make formation evaluations and methods of using are described. A neutron source (58) is positioned on the cylindrical axis of the tool while a connected gamma ray source (47) is eccentered against an interior side of the cylindrical tool. Both sources can be axially removed from the tool along its interior. Novel source-detector configurations are provided in order to accommodate the constraints of the MWD environment. Gamma ray transparent windows (50, 51) are provided through both the drill collar and an external fluid excluder (stabilizer) (21) at the positions of the gamma ray source and scintillator detectors. Neutron detectors may be of two different types at the same spacing from the source. Corrections are made for microphonic noise that arises while drilling and for natural gamma ray background. A drilling fluid density determination is made and is utilized to compensate for "borehole" or "standoff" effects.

Abstract: Silica sol is added to the beverage, preferably beer, to be filtered. In order that the pore size of the filter medium can be reduced in a simple manner and adapted to the requirements, silica sol is added, upstream of the filter medium through which the beverage flows, continuously or in a batch process using a tank, at such a rate and controlled in such a manner that the silicic acid precipitation, that is the conversion from SiO2 primary particles into SiO2 secondary particles, has taken place before the beverage has left the filter medium. The silicic acid precipitation that takes place reduces the size of the pores without closing them.
