    摘要: A class of quaternary ammonium compounds are found to be effective as corrosion inhibitors. These quaternary ammonium compounds may be used alone or in combination with additional components. For example, phosphate esters can be used with the quaternary ammonium compounds. Moreover, thiocarbonyl compounds can also be added to the corrosion inhibitor compositions. These corrosion inhibitors are effective against ferrous metal corrosion, especially under downhole conditions.

    摘要: A method for inhibiting corrosion in an aqueous medium is disclosed. The method comprises incorporating into the medium an amount of a water-soluble corrosion inhibitor sufficient to inhibit corrosion. The corrosion inhibitor comprises an N-ethoxy,2-substituted imidazoline, the N-ethoxy substituent having from one to about thirty ethoxy units and the 2-substituent being an unsaturated or polyunsaturated fatty chain of from about six to about thirty carbons. If the medium is sweet, the inhibitor further comprises a phosphate ester derived from a water-soluble oxyethylated, straight chain alcohol of from about two to about thirty carbons. Corrosion inhibitor compositions useful in such method are also disclosed.

    摘要: A method and corrosion inhibitor for inhibiting corrosion of metal equipment in an aqueous medium comprising components selected from the group consisting of Skeletonema costatum, fish, other algae, and a combination thereof. The method comprises incorporating into the medium a corrosion inhibiting amount of a water soluble corrosion inhibitor comprising an N-ethoxy, 2-substituted imidazoline. The N-ethoxy substituent comprises a quantity of ethylene oxide effective to render the imidazoline water soluble. The corrosion inhibitor is rendered more environmentally compatible by shortening the number of carbon atoms in the fatty acid chain at the 2-position of the imidazoline. The fatty acid chain consists essentially about 18 carbon atoms or less, preferably about 10 carbon atoms or less, most preferably from about 6 to about 8 carbon atoms. As the number of carbon atoms in the fatty acid chain is reduced, the efficacy of the corrosion inhibitor is increased by combination with a wetting agent, preferably an ethoxylated alcohol having from about 8 to about 10 carbon atoms.

    摘要: A shape memory effect actuated diaphragmatic anti-scald valve, including a valve housing having a fluid flow path therethrough and including a pilot chamber. There is a first valve seat within the housing and a second valve seat within the housing and downstream from said first valve seat. A pilot valve is located within the chamber of the valve housing for preventing fluid flow through the chamber in which the pilot valve element is located when the SME valve is in its normal flow position and a first valve element is retained seated on the first valve seat by the pilot valve. There are means for controlling the open and closed positions of the pilot valve depending upon the temperature of the fluid flowing through the SME valve. A diaphragm defines a second valve element for the second valve seat and located in the main path of flow for the SME valve and being in an open position when fluid is flowing through the normal flow path and the fluid is directed at the bottom thereof for holding it off the second valve seat the second valve element in its first position opens a port which allows water pressure on the top side of the center of the diaphragm urging it to close against the second valve seat and in its second position in which the second valve element is open and the diaphragm is moved to its open position unseated from the second valve seat to permit normal water flow.

    摘要: The invention provides a self-contained automatic temperature-responsive three-way line valve. A tubular valve member is axially slidable between first and second limit positions for selectively directing fluid from an inlet port to a first outlet port or a second outlet port. The valve member is disposed between a pair of opposed compression springs, one being a conventional spring biasing the valve member to the first limit position and the other being an SME spring which overcomes the bias of the first-mentioned spring when the fluid exceeds a given temperature.
