Abstract: There is disclosed a vacuum assembly including a manifold housing having one port in fluid communication via a conduit with the suction side of a pump and wherein a user site is in fluid flow via a conduit with another port or the manifold housing and wherein a vacuum relief valve assembly is positioned within the manifold housing and includes a valve disc of a spring loaded valve disc assembly in line contact with a bevelled valve seat of a valve body of the vacuum relief valve assembly thereby defining a valve seat of line contact wherein the area downstream of the valve seat is greater than the area at the valve seat.

Abstract: A tool for lifting and carrying an automotive battery and the like consists of a pair of identical sheet metal stampings in the form of L-shaped levers, pivotally joined for scissor-like action and interconnected by a carrying strap. The levers are generally planar and include a plurality of gripping teeth in a convexly curved configuration at the inner confronting faces of the L-shaped ends to provide variable spacing of the opposed operative teeth. The strap is a semi-rigid plastic and biases the levers to a partly closed position.
