Abstract: The present invention relates to novel tertiary alkanolamines useful as catalysts for preparing polyurethane foams and as additives to reduce the dynamic surface tension of aqueous solutions. The tertiary alkanolamines may be represented by formula (I): wherein A, R1–R6, and n are defined herein, and where the tertiary alkanolamine is acid-blocked with a carboxylic acid.

Abstract: A water-soluble composition including a water soluble polyamine adduct which is a reaction product of: (a) an alkoxy group modified polyepoxide resin containing an average of at least 1.5 epoxide groups per molecule; and (b) a Mannich base polyamine. The Mannich base polyamine is a reaction product of a polyamine containing at least two amino groups with a N-Mannich condensate prepared from a reaction of a phenolic compound, an aldehyde, and a secondary amine wherein the secondary amine of the N-Mannich condensate is replaced by one of the at least two amino groups of the polyamine, and wherein the ratio of the Mannich base polyamine to the alkoxy group modified polyepoxide resin contains an excess of an active amine hydrogen relative to epoxide groups so that the water soluble polyamine adduct has an amine hydrogen equivalent weight of at most 1000 based on solids content.

Abstract: An alarm system for locking receptacles having an actuating arm, such as a latch bolt, engaging a fixed portion of the receptacle, the system including a switch having an arm for engageably coacting with the actuating arm in the locked position, with the switch open. Upon removal of the actuating arm, by force or otherwise, the switch arm, which is normally biased to a closed position, is released to activate an alarm circuit which includes a power source and a horn or bell or the like. Retaining means are provided to engage the switch arm to maintan it against its bias to inactivate the alarm system when access to the locking receptacle is desired by an authorized person.
