    • A shock absorber is comprised of a cylinder defining a chamber therein, the cylinder containing a fluid; a piston rod sealingly projecting into the cylinder and being axially displaceable with respect to the cylinder; a piston being attached to the piston rod, the piston being slidably disposed within the cylinder to sealingly divide the cylinder into first and second chambers; means for permitting fluid communication between the first and second chambers; the means for permitting fluid communication being disposed in at least a portion of the piston. The fluid is comprised of a polyol ester the polyol component of which is a hindered polyol and the carboxylic acid component is a mono-carboxylic acid having from about 5 to about 18 carbon atoms.

    • Powder coating compositions having reduced volatility and improved processibility compared to conventional powder coatings consist essentially of a copolymer having pendant functionalities or pendant groups capable of reacting with a dicarboxylic acid such as the glycidyl groups of glycidyl acrylate or methacrylate copolymer and a cross-linking effective amount of a dicarboxylic acid. The reaction of the above pendant groups and the dicarboxylic acid cross-links or cures the powder coating after application to a substrate. The dicarboxylic acids according to the invention eliminate the need for a third component which is a flow control agent which improves the processibility of a two-component powder coating. The dicarboxylic acids according to the invention have a sublimation temperature great enough to decrease or prevent their vaporization during the curing of the powder coating and have a melting point low enough to impart improved flow properties to the powder coatings.
    • 与常规粉末涂料相比,具有降低的挥发性和改进的可加工性的粉末涂料组合物基本上由具有能够与二羧酸反应的侧挂官能团或侧基的共聚物组成,例如缩水甘油基丙烯酸酯或甲基丙烯酸酯共聚物的缩水甘油基和交联有效量 的二羧酸。 上述侧基与二羧酸交联的反应或在施用于基材后固化粉末涂料。 根据本发明的二羧酸消除了对改进双组分粉末涂料的可加工性的流动控制剂的第三组分的需求。 根据本发明的二羧酸具有足够大的升华温度以降低或防止其在粉末涂料固化期间的蒸发并且具有足够低的熔点以赋予粉末涂料改进的流动性质。

    • Novel modified and improved beta-diketones and their use in the extraction of copper from aqueous ammoniacal solutions containing copper values, resulting from commercial processes, including, but not limited to, leaching of copper containing ores, such as sulfidic ores, or concentrates resulting from flotation of such sulfidic ores. The novel diketones are those highly sterically hindered, which may be represented by formula (I) or (II) where in formula (I), R1 through R7 are the same or different, and are chosen from the group consisting of hydrogen, an aryl radical, an alkaryl radical containing from 6 to about 18 carbon atoms, and an alkyl radical containing from 1 to about 13 carbon atoms, with the provisos that (a) any two of R1 through R7 may together form a carbocyclic ring, (b) no more than four of R1 through R7 may be hydrogen, and (c) the overall molecule contains at least 14 carbon atoms. In formula (II), R is phenyl or alkyl substituted phenyl, R' is alkyl, and R'', R''' and R'''' are the same or different and are chosen from the group consisting of H, alkyl having from 1 to about 8 carbon atoms, and aralkyl having from 7 to about 14 carbon atoms, with the proviso that (a) no more than two of R'', R''' and R'''' are H and (b) the total number of carbons in all R groups is at least 13. The preferred beta-diketones of Formula (II) are selected from the group consisting of 1-phenyl-2-benzyl-3-isoheptyl-1,3-propanedione, 1-phenyl-2-methyl-3-isoheptyl-1,3-propanedione, 1-phenyl-4-ethyl-1,3-nonanedione and 1-phenyl-4,4-dimethyl-1,3-undecanedione.
