Abstract: A process for generating microbubbles in a body of liquid includes immersing a tubular member defining a chamber having closed and open ends in a body of liquid with the closed end facing upward and the open end downward in the body of liquid; pressurizing the interior of chamber adjacent its closed end with a gas to maintain a level of liquid within the tubular member at a desired operating level; providing a liquid flow conduit conveying a liquid stream and having a terminal end within the chamber located such that the terminal end is fixed at a level just below the operating level of the liquid to thereby cause a stream of liquid flowing through the conduit to cause periodic oscillation of the level of liquid adjacent the conduit terminal end between positions just above and just below the terminal end, thereby causing periodic entrainment of gas from above the operating level of the liquid into the stream flowing through the conduit in the form of extremely small bubbles on the order to 30 .mu.

The processor is also coupled to the second sensor and configured to generate an alarm signal in response to the second sensor signal to warn an operator of a low HMDS level in the tank.

Abstract: An aeration device disperses microbubbles into a liquid and maintains efficient transfer of gas to the liquid. The aeration device uses a number of sealed end, hollow fiber membranes that are hydrophobic and provided with pores in the walls of the tubular fibers that range from about 0.01 to 1.0 microns, so that very small bubbles are formed on the outside surface of the hollow fiber membranes. Gas pressures above the bubble point of the fiber membranes are used, and a cloud of microbubbles is expelled into the liquid as it is forced to flow past the fibers. These microbubbles provide a large surface area for the effective dissolution of gases into the liquid. The length of the hollow fiber membranes is controlled in order to obtain efficient small bubble formation.

Abstract: A steam desuperheater has a body extending into a steam line and is operated by a controlled variable water pressure source responding to the amount of superheat in the steam line. As the pressure of the supply line is increased above a predetermined level greater than the steam pressure in the steam line, a piston moves up against a calibrated spring to progressively uncover a plurality of spray openings so that increasing water pressure results in an increasingly greater amount of water sprayed into the steam line.

Abstract: A priming system for the carburetor-fuel pump of an internal combustion engine. The priming system includes a manually actuatable primer that is connected through a primer check valve either directly to a fed orifice in the carburetor throat or through the metering chamber, which communicates with the carburetor throat through main and idle orifices. In one embodiment, successive actuations of the primer bulb functions to purge the fuel pump, primer and priming lines of air and fill them with liquid fuel so that continued pumping injects priming fuel into the carburetor throat. In an alternative embodiment, the fuel pump, primer and priming lines are similarly charged but the metering chamber is also charged with fuel and the excess fuel is pumped therethrough and into the carburetor throat through the main and idle orifices. The metering chamber is left with an excess charge of fuel that results in richer operation during cranking and initial engine operation.
