Abstract: A paint brush accessory mountable on a paint brush includes a planar shield having a first edge and an opposed second end. A guide is carried on the shield adjacent the first edge for sliding engagement with a surface or edge to enable the shield to be guided in a straight line at an angle along the surface or edge. The guide is formed with an exterior surface disposed at an angle with respect to the plane of the shield to hold the shield at a constant angle from an adjoining wall when the first edge of the shield in engaged with a surface or edge. A holder is pivotally coupled to the second end of the shield to enable pivotal movement of the first end of the shield between a first position adjacent the bristles of a paint brush and a second position spaced from the bristles. The holder is releasibly mountable on the paint brush handle.

Abstract: An improved resilient torsion arrangement. The torsion arrangement is comprised of a wire-like body member having an upper portion formed in a first predetermined open geometrical configuration, a transverse portion extending across the first predetermined open geometrical configuration, and a lower portion having a second predetermined open geometrical configuration. The upper portion and the lower portion are resiliently movable toward, or away from, each other to put the transverse portion into torsion. The torsion in the transverse portion provides the resilient force resisting movement of the upper portion toward the lower portion. Proper selection of the relationships between the upper portion and the lower portion and configuration of the transverse portion can provide predetermined relationships between the force required to move the upper portion toward, and away from, the lower portion and the separation between the upper portion and the lower portion.

Abstract: An improved containment barrier or boom section of the type having a flotation means for supporting the barrier or boom on the surface of a liquid body such as a lake, harbor, river, ocean, or the like, and also having a sinking means such as a flexible skirt section coupled to the bottom of the flotation means and extending below the surface, the skirt section containing ballast and, preferably, a tension member, to contain contamination or material floating on or near the surface, such as an oil spill, usually on one side thereof. End connectors are provided at each end of the barrier section for coupling to additional barrier or boom sections and/or to a towing means for deployment and/or recovery. The flotation means comprises an elongated tubular member having a cavity extending throughout the elongated length thereof and the tubular member is flexible.
