Abstract: Disclosed is an improved mixing eductor (10) of the type wherein the primary liquid (17), e.g., water, is in a main stream (201) flowing in a downstream direction. A venturi tube (51) is in the eductor (10) and has an annular sharp edge (131) in the main stream (201), thereby dividing such stream (201) into a primary stream (179) and a secondary stream (181) around the primary stream (179). The eductor (10) has an air gap (103) and a flow guide (47) downstream thereof. In a specific embodiment, the flow guide (47) is annular around the venturi tube (51) and the tube (51) and the guide (47) are in spaced telescoped relationship. Several embodiments of the eductor (10) and a new method for mixing liquids are disclosed.

Abstract: A novel ethylenically-unsaturated 1,3-diketoamide functional compound, polymers comprised thereof, and latex formulations containing polymeric ingredients having 1,3-diketoamide functional pendant moieties are disclosed. The 1,3-diketoamide functional pendant moieties have excellent hydrolytic stability.

Abstract: This invention provides a composition and method for maintaining the appearance of stone floor surfaces such as marble that avoids the need for use of oxalic acid. This is provided by a stone floor surface crystallizer composition comprising from about 12% to 25% of a silicofluoride crystallizing agent such as magnesium silicofluoride; from about 15% to 25% of at least one fatty acid containing from about 16 to 22 carbon atoms such as stearic acid or mixtures of palhitic, stearic and oleic acids; from about 25% to 45% of at least one particulate abrasive, more preferably, an aluminum oxide abrasive; from about 80% to 140%, based upon the stoichiometric amount of carboxyl groups present in the fatty acid of the composition, of at least one alkaline neutralizing agent for the fatty acid such as a volatile amine such as triethanolamine; from about 0.1% to 2%, of a silicone fluid such as polydimethylsiloxane fluid having a viscosity of from about 100 to 2000 centistokes (0.01 to 0.
