Submerged gas evaporators and reactors
ActiveUS7416172B2Increased turbulenceEnhanced mixing processCarburetting airUsing liquid separation agentChemical reactionHigh rate
A submerged gas processor in the form of an evaporator or a submerged gas reactor includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a process fluid inlet that provides a process fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. A weir is disposed within the vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the vessel and a second fluid circulation path between a second weir end and an upper end of the vessel. During operation, gas introduced through the tube mixes with the process fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the process fluid. This turbulent flow develops a significant amount of interfacial surface area between the gas and the process fluid resulting in a reduction of the required residence time of the gas within the process fluid to; achieve thermal equilibrium and / or to drive chemical reactions to completion, all of which leads to a more efficient and complete evaporation, chemical reaction, or combined evaporation and chemical reaction process.

Reciprocating weight exercise apparatus
InactiveUS7175575B1Improve versatilityGreat momentumClubsResilient force resistorsWeight trainReciprocating motion
A reciprocating exercise apparatus with a tube that has a slidable weight. The sliding action of the weight is damped by coil springs. To increase the types of exercises that can be performed with the apparatus there is a pair of stationary handles at the ends of the tube and a pair of handles that slide along the length of tube. The slidable handles are seated on sleeves with a swaged end. This configuration allows for exercises where the weight reciprocates alternately compressing one spring or the other and that can be performed with one hand or two. Auxiliary weights can be attached so a single unit is suitable for users with varying degrees of strength.

Method for injecting gaseous fuels into an internal combustion engine at high pressures
ActiveUS7162995B2Speed up the flowGreat momentumInternal combustion piston enginesFuel supply apparatusShock waveCombustion chamber
A method directly injects gaseous fuel into the combustion chamber of an internal combustion engine. The compressibility of the gaseous fuel is used to provide a fuel to the combustion chamber that is injected over all engine operating conditions at pressures that result in fuel jet speeds beyond the injector nozzle in excess of sonic speeds as determined in reference to the combustion chamber environment. The resulting fuel injection speed results in the fuel passing through shock waves within the combustion chamber, which, in turn, promotes combustion of the fuel by promoting turbulence and mixing of the fuel and intake charge within the combustion chamber where fuel burns in a non-premixed combustion mode.

Gyrostabilizer for small boats
InactiveUS7240630B2Large counter roll torqueShorten the timeMechanical apparatusVessel movement reduction by gyroscopesAngular momentumAngular velocity
A gyrostabilizer system that counteracts the natural rolling motion of a small boat or vessel. The invention constitutes an improvement in prior art systems of this type in that the system weighs less because it has a much lighter rotor made of composite materials spinning at much higher speeds. The gyrostabilizer system includes a lightweight rotor spinning at very high speeds to attain a large angular momentum. The mass of the rotor is concentrated away from the spin axis of the rotor to maximize angular momentum while minimizing weight. The rotor is mounted in a frame that, in turn, is mounted on gimbals so that the frame can be rotated about an axis that is normal to the longitudinal roll axis of the vessel. When the rotor is rotated about the gimbals, a torque is created that opposes the torque created by the sea and reduces the rolling motion of the vessel. The rotor may be mounted in an evacuated chamber to reduce air drag. Rotation of the rotor frame around the gimbal axis is controlled by an active servo system using information provided by roll angular position and angular velocity sensors.

Centripetal Separation System for Cleaning Particulate-Pervaded Air or Gas
ActiveUS20150128544A1Increase pressureEasy to separateCombination devicesAuxillary pretreatmentParticulatesImpeller
Some embodiments provide a centripetal air or gas cleaning apparatus for removing particulates from air or gas. The apparatus comprises an inlet, housing, impeller, a clean air outlet, and a particulate outlet. The housing has an inner conical surface. The impeller's rotation creates negative pressure towards the inlet that intakes particulate-pervaded air or gas into the housing. The rotation also induces an accelerating force that throws the particulate-pervaded air or gas against the outer walls of the housing. Here, the particulates separate from the air or gas, penetrate a high-pressure zone, and are ejected through the particulate outlet located in the high-pressure zone. The air or gas, having less inertia, deflects away from the high-pressure zone where it is then subjected to a centripetal force that drives the air or gas towards the center of the housing behind the impeller where it is ejected through the clean air outlet.

Therefore, differential pressure is formed between the air suction groove and the air jet groove to drive fluids to spray from the downstream of the blade to the upstream of the blade, and the air jet groove is positioned close to the suction surface of the front edge of the blade and exactly aligned to a leakage vortex generating area of the blade, so that leakage flow can be suppressed, and further the stall margin of the air compressor is increased. Moreover, as an air jet direction is consistent with a main flow direction, mixing loss of an air jet area and a main flow area is decreased, the momentum of a boundary layer of the wall surface of the casing is increased, and positive effects are achieved for the efficiency of the air compressor.
