Abstract: The disclosure includes structured siloxanes which can foam in low surface tension solutions. The foaming compositions may form foam in alcohol/water and hydrocarbon condensates. The foaming compositions may replace surfactants in other compositions. The disclosure also includes sterilizing alcohol compositions, cleaning compositions, such as hard surface cleaners, warewash detergents, rinse aids, hand sanitizers, and the like which incorporate the same.

Abstract: A method for drilling formations below the bottom of a body of water includes disposing a drilling system on the bottom of the body of water. The formations are drilled by rotating a first drill rod having a first core barrel latched therein and advancing the drill rod longitudinally. At a selected longitudinal position, an upper end of the first drill rod is opened and a cable having a latching device at an end thereof is lowered into the first drill rod. The winch is retracted to retrieve the first core barrel. The first core barrel is laterally displaced from the first drill rod. A second core barrel is inserted into the first drill rod and latched therein. A second drill rod is affixed to the upper end of the first drill rod. Drilling the formation is then resumed by longitudinally advancing and rotating the first and second drill rods.

Abstract: A method of sizing paper for use in applications which require resistance to liquids comprising incorporating in the paper a size composition comprising one or more alkenyl succinic anhydride (ASA) compounds prepared from the reaction of maleic anhydride and one or more substantially symmetrical C20-C28 internal olefins.
