    摘要: A turbidimeter with a pair of movable and stationary elements interconnected by a vertically-aligned hinge pin. Interior walls of these elements, when fully closed, define a cylindrical through passageway and an annular shelf which extends outwardly from its upper end. Otherwise, the stationary element, when the movable element has been pivoted away from it, defines one-half of the through passageway bisected lengthwise and a semi-annular shelf. Prior to use, a transparent cuvette can be slideably inserted sideways into the bisected through passageway and suspended there by protrusions on a cap threadedly engaged with the cuvette. The protrusions include a cap plate and an annular support shoulder which, in use, rests on the shelf. With its cuvette insertable sideways, an upflow sample cell, complete with supply and drain fittings fluidly connected to the cuvette, can be readily moved into and out of the turbidimeter to facilitate calibration procedures.

    摘要: There is provided a tackifier composition especially suited for use with natural rubber latex and formed from an olefin resin, preferably a polymerized terpene hydrocarbon resin condensed with an unsaturated carboxylic acid or anhydride, optionally partially esterified with a C.sub.1 -C.sub.30 alcohol or phenol, and neutralized with a base, preferably a volatile base such as an amine, and then dispersed in an aqueous medium. The tackifier when added to a latex forms compositions useful particularly as pressure sensitive adhesives.

    摘要: There is provided a novel class of alkoxy silanes useful as corrosion inhibitors for metal surfaces and characterized by an alkylene group attached to silicon through a Si--C linkage. These compounds also contain nitrogen as an amine or an imine group in a linear or cyclic structure. Sulfur and/or a carbonyl or thiocarbonyl group may also be present. The invention also provides a method of inhibiting corrosion of metal surfaces by applying a coating containing or consisting of a novel silane as above described.

    摘要: Resinous coating compositions can be expediently heat cured by phenol compounds containing at least two methylene amine groups which are conjugated with the aromatic alcohol group or phenol group. The hydroxyl group substantially increase the reactivity of the aminomethyl functionality whereby active hydrogen containing resins can be effectively cross-linked.

    摘要翻译: 树脂涂料组合物可以方便地通过含有至少两个与芳族醇基团或苯酚基团共轭的亚甲基胺基团的酚化合物加热固化。 羟基基本上增加了氨基甲基官能团的反应性,因此含活性氢的树脂可以有效地交联。
