Abstract: An air conditioning system for automobile having a heater core capable of heating the interior in good efficiency is to be provided. Such a heater core is supplied with the coolant having bubbles removed, and thereby the efficiency of heat exchange is enhanced and the noise is reduced. On the internal combustion engine is mounted a water outlet (bubble separating means) 3 having a receiving chamber 8 that the coolant after cooling the engine flows in. In the downstream position of the chamber 8 is formed a communicating portion 9 of narrowed sectional area and a feeding chamber 10 of increased sectional area in turn. The flowing velocity of the coolant is increased in the communicating portion 9 and decreased in the feeding chamber 10 and thereby it is possible to make bubbles in the coolant float up and separate out. As a result, the coolant without bubbles may be fed to the heater core 7 through a feeding portion 11.

Abstract: The purpose of this system is to separate components of a molecule from the larger molecule or separate a molecule into smaller pieces. This system uses the shearing and/or breaking of molecular bonds using pressure waves, sudden pressure differentials, rotary movements, high velocity collisions to separate the molecule, or any combination of these methods. The system uses high voltage through no voltage to facilitate the separated or broken particles to remain in a separated state. For simplification purposes in the patent the drawings will show the separation of hydrogen from water molecules rather than to refer to all combinations; however, this patent refers in general to the separation of molecules/atoms of any size, shape, or configuration into a baser unit, separation of molecular components, or for distillation purposes. The process combinations described below can be used in any industry and for any reason without limitation.

Abstract: A liquid-gas separator assembly is used in separating gas bubbles from a liquid coolant which liquid coolant is used in a polymer electrolyte membrane (PEM) fuel cell power plant. The assembly includes a cylindrical housing containing a central tube which is surrounded by an annular chamber.

Abstract: This disclosure relates to a method for deaerating a liquid layer such as a coating solution using electrostatic forces. A flow of charged particles is created above and moved towards a low conductivity liquid layer. The flow of charged particles causes localized thinning of the liquid layer which facilitates the removal of bubbles of entrained gas from the liquid by bringing those bubbles closer to the exposed surface of the liquid and rupturing them at that surface. This electrostatic deaeration technique is combined with other non-electrostatic liquid layer thinning techniques or degassing techniques to further facilitate removal of bubbles from the liquid in preparation of further processing of the liquid. The liquid layer may be stationary or flowing with respect to the application of charge particles.

Abstract: A system for rapid collection of large volumes of dissolved gases from groundwater pumps the water from a large-diameter passage through a small-diameter restrictor passage, and then into a flow-through collection chamber. The small-diameter passage causes a drop in the hydrostatic pressure of the groundwater traveling therein, causing spontaneous ebullition of gas bubbles which are then collected in the collection chamber. Testing reveals that the gases are collected in proportion to their presence in the groundwater, and thus the system allows accurate quantification of concentrations of dissolved gas in groundwater. The system may beneficially be made easily portable, thereby allowing its use in the field as well as in laboratory settings.
