Abstract: Atomic oxygen is provided for the purpose of promoting reliable ignition and smooth combustion in a spark ignition internal combustion engine is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the flammable mixture of air and gasoline vapor prior to the time of ignition. The introduction of N2O may take place in the intake manifold, in the stream of exhaust gas being returned as part of the EGR process, or directly into the combustion chamber (for example through a small orifice in the base of the spark plug or through a small nozzle located elsewhere in the cylinder head). Introduction of N2O directly into the combustion chamber may be continuous, or it may be pulsed so as to occur at the time of, or shortly before, spark ignition.

Abstract: A sanitizing hand dryer comprises a dryer housing having an inlet air channel and an outlet air channel.

The sanitizing system within the outlet air channel includes at least one of a second air filter, a second ozone generator, a second sanitizing light source, a second photocatalytic oxidation system, a second ion generator, and a second electrostatic precipitator.

Abstract: One approach to providing atomic oxygen for the purpose of promoting more rapid and compact combustion is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the compressed air in the cylinder before or close to the time of ignition. The introduction of N2O may take place in the intake manifold, directly into the combustion chamber through a small orifice in the base of the fuel injector or a small nozzle located elsewhere in the cylinder head, or the N2O can be added as a solute to the injected fuel.

Abstract: An exemplary embodiment of a UV light injector assembly is used to apply intense light that includes short wavelength UV to the interior of an engine cylinder near the desired time of fuel ignition. In an example embodiment, the light is produced by a short-arc xenon flash lamp. This flash lamp includes an integral reflector (e.g., a parabolic reflector) to collimate the majority of its light into parallel rays. The assembly includes a window for passing UV light into the cylinder. To direct the collimated rays of light from the flash lamp through the window a UV-transparent condensing lens is used to focus the light from the flash lamp onto the window.

Abstract: A diesel engine fuel delivery system is equipped for addition of N2O to the fuel supply of a diesel engine. Fuel from a tank passes through an outlet tube to a low pressure pump which delivers it through a fuel filter. Simultaneously liquid N2O from a pressurized tank passes through a metering valve where it merges with the fuel before passing through a high, constant pressure, on-demand pump. The N2O-loaded fuel then enters a high pressure manifold, called a common rail, where its pressure is monitored by a sensor before it enters individual injectors which spray it, with proper timing into the combustion zone of each cylinder. The desired fuel injection timing can be adjusted and controlled by an electronic engine control unit similar to those commonly installed on modern vehicular diesel engines.

Abstract: A fire protective composite comprising a jacketed fibrous endothermic mat and method of wrapping thereof, the jacket material preferably including impregnated fiberglass fabric, the composite designed for fire protection of structural elements such as steel I-beams and complex joints, electrical conduits and cable trays, LP-gas container and vessel skirts and valves.

Abstract: A lavatory wash station includes a wash station housing, a sink basin connected to a front of the housing, wherein the sink basin has a rim, and a sanitizing hand dryer assembly having an air intake and an exit nozzle at the front of the housing. The air intake and the exit nozzle are connected by a dryer flow path and the exit nozzle is disposed at the front of the housing above the rim, where the exit nozzle provides air flow in a substantially downward vertical direction into the sink basin and the sanitizing hand dryer includes an ion generator that treats the air passing through the hand dryer.

Abstract: Embodiments of the invention include a method for engaging a dart with a net. A dart is thrown toward a net. When the dart hits the net, the nose of the dart passes through an opening in the net for subsequently, lodging strands of the net in a recess situated behind the nose of the dart. Embodiments further include a recreational toy assembly having in combination a net and a dart. One or more strands of the net lodge in a recess behind the nose of the dart for coupling the dart to the net. The dart remains engaged to the net until the dart is removed from engagement with the net. For disengaging the dart from the net, the strand(s) is/are removed from the recess such that the nose of the dart may be passed out of opening in the net. The strands of the net provide the boundary or perimeter of the opening.
