Abstract: A head shield device having a frame and a replaceable lens. An engagement axle having an large dimension and a small dimension is attached to the frame. The lens defines an aperture with a neck and an enlarged inner body. The small dimension of the axle is adapted to pass through the neck and rotation of the axle to the large dimension locks the lens in place on the frame. The axle rotation is controlled by a control device located on a tab assembly forming the engagement axle.

Abstract: A method and apparatus for recharging depleted tennis balls that uses compressed carbon dioxide. A recharge pressure vessel including a cylinder with a closed end and a spaced apart open end with a connecting wall forming a charging chamber. A pressure port proximate the open end permits gas entry and exit for charging. The chamber may be filled with any number of discharged tennis balls and then is sealed and charged with high pressure heavy molecular weight gas such as carbon dioxide. The vessel is then agitated to jostle the inserted balls and within 4 to 5 days, the balls will become fully pressurized and the pressure may be released and the recharged balls remove from the vessel.
