Abstract: Disclosed herein are polymers formed by the condensation of bis(hydroxycarbyl)-aminophenolic compounds with aldehydes. The condensation polymers include one or more repeat units having bis(hydroxycarbyl)amino functionality. The hydroxyl groups of the bis(hydroxycarbyl)amino functionalities are available for further condensation with an epoxide, such as ethylene oxide, to yield a polyalkoxylated polymer. The polymers are useful as antipolymerants, polymerization retardants, surfactants, or a combination of these in one or more industrial systems.

Abstract: The present invention provides improved methods for purifying and/or removing multiply charged cations and suspended solids from water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing multiply charged cations and suspended solids from an aqueous or oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is used in the presence of a source of alkalinity or anionic reactant as well as surfactant in appropriate ratios to facilitate multiply charged cation and suspended solids removal for water purification in any of a number of commercial, environmental and industrial applications.

Abstract: An automated robotic food handling or preparation apparatus includes one or more food contact surfaces and an antimicrobial lighting fixture. The antimicrobial lighting fixture includes an enclosure forming a sanitization chamber and one or more antimicrobial lighting elements, wherein each element emits light at a wavelength, irradiance, and direction sufficient to inactivate one or more microorganisms on a target surface(s) within the sanitization chamber. The automated food handling apparatus subjects itself to an antimicrobial lighting treatment within the sanitization chamber upon detection of one or more conditions. The systems and/or methods of the present disclosure may sanitize food contact surfaces of automated robotic food equipment and help reduce the frequency at which such food contact surfaces need to be manually sanitized to keep microbial growth below acceptable levels.
