Abstract: A baseball bat has its handle, shaped to be grasped by the hand of a user, extending on into an enlarged hitting portion that continues away from the handle. Included in that hitting portion is a velocity meter situated in a cavity that extends longitudinally inward toward the handle from the outer end. A plunger is slidably received within that cavity and is resiliently held in place. Also included is an indicator which informs as to the amount of movement of the plunger outwardly from within the cavity as a result of the swinging of the bat by the user.

Abstract: A GAS PRESSURE CHARGED, TUBULAR DIAPHRAGM, PRESSURE ACCUMULATOR HAVING A FLOW TUBE FORMED OF SINTERED METAL PROVIDING COMMUNICATION PASSAGES FOR THE TUBULAR DIAPHRAGM AND A LIQUID UNDER PRESSURE IN THE FLOW TUBE, SO THAT THE GAS ABSORBS SUDDEN SURGES OF FLOW AND PRESSURE IN THE LIQUID FLOW LINE. THE SINTERED METAL FLOW TUBE IN THE ACCUMULATOR PROVIDES FULL OPEN COMMUNICATION BETWEEN THE LIQUID AND THE DIAPHRAGM BUT PREVENTS EXTRUDING OF THE DIAPHRAGM MATERIAL THROUGH THE OPENINGS AT HIGH GAS PRESSURES AND LOW LIQUID PRESSURES.
