Abstract: This invention is a nitrous oxide delivery system to improve engine power in which the nitrous oxide leaves its storage bottle as a vapor rather than conventional liquid delivery systems in which it leaves as a liquid. This system can therefore use a relatively simple pressure regulator and fixed orifice to maintain an essentially constant nitrous oxide mass flow rate over a wide range of storage bottle pressure. The nitrous oxide which enters the engine does not contain any ice crystals and will not cause icing, therefore allowing introduction of the nitrous virtually anywhere in the engine's induction tract.

Abstract: This invention is a golf tee having an aerodynamic drag portion with a relatively large frontal area and aerodynamic drag coefficient, an intentionally minimized mass, and a subsequent reduction in flight distance upon being struck with a golf club. This reduced flight distance coupled with the relatively large area of the drag portion makes this tee relatively easy to find. It is economically feasible, therefore, to make this tee from a virtually indestructible but relatively more expensive material such as polyurethane. The resulting tee has significantly greater operational life than conventional tees.

Abstract: This invention is a variable orifice for controlling the mass flow rate of nitrous oxide in a liquid delivery ststem, this orifice having an effective size, or area, which changes with changes in the nitrous oxide pressure applied to it. Several design parameters can be changed to provide the desired effective orifice area as a function of pressure. This variable orifice can be designed to maintain an essentially constant nitrous oxide delivery rate over a wide range of nitrous oxide pressures.
