Abstract: A mounting bracket comprising two cooperating elements pivotally mounted together for pivotal movement between a first open position to dispose the bracket around a support beam or the like, and a second closed position at which the mounting bracket is securely held in place on the support beam. The two cooperating elements each include an engagement wall portion for engaging the support beam and a bearing wall portion for supporting a fixture, such engagement wall portions and bearing wall portions, respectively, being separated, at the first open position of the cooperating elements, and being adjacent one another in coplanar relationship at the second closed position of the cooperating elements.

Abstract: The addition of an inner salt of a quaternized pyridine carboxamide, preferably 1-benzyl pyridinium-3-carboxamide to aqueous alkaline electroplating baths containing zinc and cadmium ions results in smooth, bright deposits of these metals. High plating efficiency with low consumption of the additive compound is obtained using it either alone or in combination with small amounts of nicotinamide.

Abstract: Zinc, copper and/or iron impurities ordinarily associated with nickel or cobalt electroplating baths can be removed from solution by introducing an amount of a predetermined and selected alkylthiuram sulfide compound into the electroplating bath sufficient to convert the zinc, copper and/or iron impurities into relatively insoluble metal salts. The insoluble salts may then be removed from the bath by passing the treated solution through a standard filtering system.
