Abstract:
A method of operating an internal combustion engine comprises the steps of (a) pressurizing a liquid fuel to a pressure above 150 psig; (b) heating the liquid fuel to a temperature above 500° F. to produce a heated liquid fuel; (c) suddenly reducing the pressure of the heated liquid fuel sufficiently to vaporize the heated liquid fuel to form a vaporized hot fuel; (d) combining the vaporized hot fuel with oxygen to form a vaporized hot fuel/oxygen mixture; (e) introducing the vaporized hot fuel/oxygen mixture into the internal combustion engine; and (f) combusting the vaporized hot fuel/oxygen mixture within the internal combustion engine.
Abstract:
A water recreational apparatus, such as a portable spa, hot tub, above ground pool, a recirculating bath tub has a water recirculation system wherein water from the basin of the apparatus is recycled through a pump in water jets disposed in the side walls of the basin. At least one water input valve for controlling the flow of water into one or more of the water jets is controllable by a remote controllable motor. A control panel for controlling the remote controllable motor is disposed proximate to at least one of the seat locations within the water basin.
Abstract:
A water recreational apparatus has a water basin, a filter and a pump. The side walls of the water basin have side doors to allow the flow of water from the water basin to the filter. A spring or other biasing means is provided to bias the side wall doors to a closed position when the pump is not operating, but allowing the side doors to open when the pump is operating.
