The device (1) includes a probe (6) configured to measure a concentration of the gas dissolved in water, and the probe (6) is arranged in the housing (100) of the device (1).

Abstract: Milk frothing apparatus (1) having a container (2) which delimits a supply space (3) for milk (4), and having a frothing element which can be rotated by electric motor with the function of frothing the milk (4) by way of rotation of the frothing element, the supply space being assigned a filling opening (22), wherein the frothing element is configured as a feed rotor (7), with the function of conveying, by way of the rotation of said feed rotor (7), the milk which was frothed by way of rotation of the frothing element (7) to an outlet (10) through a milk froth line (9) of the milk frothing apparatus (1), and wherein the feed rotor (7) is arranged at least in sections, preferably completely, in a frothing chamber (6) which is connected in a fluid-conducting manner to the supply space (3), from which frothing chamber (6) the milk froth line (9) opens, and wherein the feed rotor (7) is assigned at least one airline (15, 15?) for sucking in air by way of the rotation of the feed rotor (7), and wherein the air lin

Abstract: A liquid aerator in one embodiment includes an air deliverer having a bulb pump portion formed integrally with a stem portion; a one-way valve located in the bulb pump portion of the air deliverer; and a porous diffuser located at a distal end of the stem portion of the air deliverer. A liquid aerator in another embodiment includes an air deliverer having a bottle shape including a larger diameter base portion formed integrally with a narrower diameter neck portion; a one-way valve located in the base portion of the air deliverer; and a porous diffuser located at a distal end of the neck portion of the air deliverer.

Abstract: A heat dissipation device includes an air current producing unit and an electromagnet unit separately disposed on a substrate. The air current producing unit includes a resilient fan body mounted to the substrate and having an unrestrained end, and a magnetic component disposed on the fan body. The electromagnet unit is configured to generate a varying magnetic field that acts on the magnetic component so as to cause the fan body to sway, thereby producing air current.

Abstract: A liquid container aeration system for replenishing gases dissolved in a selected liquid present in an interior of said liquid container that checks on an electrical power source capability to continue operation and allows selected liquid substitution in the interior of the container.

Abstract: A live well oxygenator includes a vessel having walls constructed of corrosion resistant material. The walls enclose a chamber that functions as a gaseous oxygen storage chamber. Fittings are disposed on the walls so that gaseous oxygen may be supplied to the chamber from an outside source. The vessel is equipped with a water pump and water return pipe which are in fluid communication with the water in a live well to provide for circulation of the water through the vessel. The water pump sucks water from the live well so that it flows through pump discharge piping. The pump discharge piping is positioned in the oxygen storage chamber. An induction fitting on the discharge piping functions to induct oxygen into the water stream in finely divided bubbles.

Abstract: A fish bait system includes a fish compartment and a filter compartment for maintaining bait fish in a healthy condition for prolonged periods prior to use. The fish bait system allows water to be pumped from the fish compartment through a filter having a standard non-woven reusable media whereby the filtered water is returned through an air infuser to the fish compartment. The infuser is mounted on the wall separating the fish and filter compartments and saturates the filtered water with oxygen to insure the fish are provided with an adequate oxygen supply. The removable filter media can be easily extracted from the filter housing, rinsed or replaced and returned to the filter in a quick and efficient manner.

Abstract: A portable aerator may be operated utilizing either internal direct current power or external alternating or direct current power. The aerator includes a housing in which are mounted an aerator pump and a motor for driving the aerator pump. The motor is connected to positive and negative contacts, which are interengagable by one or more direct current batteries. A jack mounted to the housing is electrically connected to the contacts and the jack is operably interengagable with an external adapter that is selectively attached to an external alternating or direct current power supply for supplying external power to the contacts and thereby to the motor. A switch may be employed to selectively provide power to and disconnect power from the motor.

Abstract: A high efficiency impeller-type aerator designed for aeration of the water supply of aquatic organisms has a first impeller, a second impeller, and a pump casing having at least one water inlet, one air inlet, and one water outlet. The first and second impellers are disposed between the pump water inlet and outlet, and the pump casing includes constricted portions in association with the first and second impeller to define axial flow direction boundaries. The air inlet is located at the constricted portion, and the axial flow direction boundaries define a channel through which the second impeller urge water to facilitate low pressure that creates a venturi which causes air suction at the pump air inlet.

Abstract: A high efficiency impeller-type aerator designed for aeration of the water supply of aquatic organisms has a booster impeller, a main mincing impeller, and a pump casing having at least one water inlet, one air inlet, and one water outlet, with the pumping and mincing impellers disposed between the pump casing water inlet and outlet, and wherein the air inlet is positioned advantageously between the booster pump and the main mincing impeller and is in communication with air, and wherein the water-inlet and outlet are in communication with water. The efficiency of the pump is retained while the bubbles produced in accordance with the present invention are advantageously small.
