Abstract: A process for preparing a surfactant, useful for dispersing tackifier resins in aqueous media, comprises reacting an ?,?-unsaturated carboxylic acid or anhydride, or an ester thereof, with a terpene- or hydrocarbon-based resin to form an adduct, then reacting the adduct with a polyalkylene polyol to yield the surfactant. In a related embodiment, the surfactant is subsequently functionalized. Also disclosed are surfactants prepared using a disclosed process; compositions comprising a disclosed surfactant and a tackifier resin; aqueous dispersions comprising a disclosed surfactant; tackifier resin and water; adhesive compositions comprising a disclosed aqueous dispersion and a polymer latex; and pressure sensitive adhesive overlays prepared using a disclosed adhesive composition.

Abstract: A feather seal is provided having a first element and a second element. The first element includes a pair of protrusions and the second element includes a slot for receiving the first element. The first element is slidably received within the slot of the second element, and the protrusions limit the travel of the first and second element relative to one another.

Abstract: An apparatus and method is provided for locking side entry blades, in a rotor, such as used in compressors, turbines and fans. The apparatus utilizes arcuate locking devices retained in a circumferential groove in the periphery of the rotor. Each locking device features a key which engages a keyway in the side of the blade root shank. Use of the locking devices does not require that the blades having abutting platforms.
