Abstract: A baffle assembly for intercepting paint particles passing through a spray booth is disclosed. The baffle assembly includes an inner plate and an outer plate adjacent each end or edge of the inner plate. The inner plate is comprised of a central planar portion, which is oriented substantially perpendicular to the direction of air flow, and having outer ends which are curved in an upstream direction and inwardly toward one another. Each outer plate includes a curved portion which terminates in a semi-circular portion. The inner plate is received and positioned within the outer plates so that each of its outer ends is substantially surrounded by and equidistant from its adjacent outer plate. In this manner, air flows between the inner plate and the outer plate in a first curved direction and then in a second opposite curved direction.

Abstract: This invention relates to novel hydroxy-functional polyester diluents, and more particularly, to acrylic-modified hydroxy-functional polyester reactive diluents useful for blending with a variety of thermosetting or thermoplastic film-forming polymers. More specifically, the hydroxy-functional polyester reactive diluents are essentially low molecular weight polyesters derived from triols, and a combination of unsaturated monocarboxylic acids and saturated monocarboxylic acids.

The first and second halves of the body member are substantially mirror images of one another. A central axis divides the first and second halves and intersects a mid-point at the fold in the body member in the display position.
