Abstract
Apparatus for repressuring a tennis ball or similar play ball, which has lost a portion of its initial inflation pressure, in which a container or enclosure for the ball contains a chemical and a suitable fluid that reacts with the chemical to generate a gas at atmospheric pressure capable of diffusing through the permeable elastomeric material of the ball to elevate the total pressure within the ball toward its initial pressure value.
Claims11
Apparatus for repressuring hollow permeable plays balls inflated by a first gaseous medium to above atmospheric pressure, comprising a container for receiving one or more of the balls, the interior of said container being at atmospheric pressure, and a means for providing a second gaseous medium in said container externally of one or more of the balls, the second gaseous medium being capable of diffusing through said one or more permeable balls to increase the pressure therein, said means being at atmospheric pressure and said second gaseous medium being differemt from said first gaseous medium.
