Abstract: A paper beading apparatus, includes a hopper having a body defining a chamber for holding a quantity of joint compound, and having an open upper end, an upper rim, and a lower end; a lid pivotally secured to the body for movement between an open position and a closed position, wherein in the closed position, the lid engages the open upper rim, the lid having a releasably sealable air port; and a base configured for and accommodating the hopper lower end, for receiving joint compound, and for applying the joint compound to a corner paper bead.

Abstract: A power tool in one embodiment is a table saw which includes a swing arm assembly movable along a swing path, an actuator configured to force the swing arm assembly away from a first swing arm position and toward a second swing arm position, and a riving knife positioned outwardly of the swing arm assembly when the swing arm assembly is in the first swing arm position, the riving knife including a channel with a first end portion and a second end portion, a first curved channel portion with a first center of curvature and located between the first end portion and the second end portion, and a second curved channel portion with a second center of curvature and located between the first end portion and the second end portion, wherein the first center of curvature is not coincident with the second center of curvature.

Abstract: A power tool in one embodiment is a table saw which includes a latch hold mechanism, a swing arm movable along a swing arm path between a first position adjacent the latch hold mechanism and a second position spaced apart from the latch hold mechanism, a latch movable between a first position whereat the swing arm is maintained at the first position and a second position whereat the swing arm is not maintained at the first position, an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first position, and a control system configured to control the actuating device to transfer a force to the swing arm when the swing arm is maintained at the first position sufficient to move the latch from the first position to the second position.
