A foamable phenolic resole composition is foamed and cured with an acid curing agent which is an anhydrous aryl sulfonic acid which has a pKa of less than about 2.0 and which reduces the compatibility of the resole with water, e.g. benzene, toluene or xylene sulfonic acids. The phenolic foam formed has cell walls which are substantially free of perforations. The preferred anhydrous aryl sulfonic a...

Removal of ambient oxygen from aqueous liquids is effectively catalyzed by enzymatic deoxygenation systems comprising alcohol oxidase in the presence of alcohol optionally with catalase. Suitable deoxygenation systems described can be used to alleviate corrosion and oxidative degradation in areas such as oil field fluids, circulating water systems, water storage tanks, alcoholic beverages and food...

A method and apparatus of detecting fractures along the wall of a formation, such as a well formed by test-drilling, provides for the transmission of ultrasonic signals in a direction essentially perpendicular to the wall from a position spaced from the wall by a predetermined distance and the reception of the ultrasonic signals which may be reflected by the wall. The space of predetermined thickn...
