| 6029955 | Counterbalanced dual submarine-type liquid mixer pairs A counterbalanced, dual submarine-type liquid mixer provides a pair of counterbalanced mixing devices that move at opposing ends of a balance bar suspended above the surface of a liquid to be mixed. The bar is able to pivot so as to vertically move its en... | 02/29/2000 |
| 5417147 | Apparatus for carbonating liquids at municipal water pressure Apparatus is provided for automatically carbonating a liquid. A pressure vessel receives carbonating gas at a pressure P1 via a first input, and a supply of liquid at a pressure P2 via a second input. P2 is greater than P | 05/23/1995 |
| 4673443 | Continuous ionizer for semiconductor manufacturing processes A continuous ionizer adapted to introduce selected ions into a continually flowing stream of liquid. To ensure that a maximum concentration of ions is incorporated, the continuous ionizer is configured so that turbulent and intimate mixing of the ionizing... | 06/16/1987 |
| 4548232 | Valve assembly A check valve includes an elongated housing having an inlet port at the upper end and an outlet port at a lower end and a float movable therein. An exterior valve seat surrounds the outlet and a valve stem connected to the float extends through the outlet... | 10/22/1985 |
| 4436674 | Vapor mass flow control system In a system for delivering vapor from a container partially filled with liquid to be vaporized by bubbling a carrier gas therethrough, the flow of the vapor is precisely regulated by a controller so as to provide a uniform mass flow rate of vapor. The con... | 03/13/1984 |
| 4393013 | Vapor mass flow control system A system for precisely controlling the mass flow rate of vapor from a bubbler by a carrier gas stream.... | 07/12/1983 |

| 4339152 | Method and apparatus for mixing gaseous oxidant and lixiviant in an in situ leach operation Method and apparatus for mixing a gaseous oxidant (e.g., oxygen) and a lixiviant (e.g., an aqueous carbonate solution) at a downhole location before the oxygen-saturated lixiviant is injected into a formation to be leached. The invention involves establis... | 07/13/1982 |
| 4313897 | Gas and liquid admixing system Shown is a portable dispensing system schematically, with a motorless carbonator of the continuous flow type shown in detail employing a needle type valve that is removable as a unit for replacement or repair and which operates in combination with a float... | 02/02/1982 |
| 4271097 | Gas and liquid ad-mixing system Shown is a horizontal model of a continuous flow motorless carbonator, which carbonates water from a pressurized source as it is drawn, with a pivoted float element connected mechanically to a gas inlet valve assembly and having an extended arm to receive... | 06/02/1981 |
| 4192836 | Respiratory gas humidifier A respiratory gas humidifier comprises a closed water reservoir having a water level therein which is maintained so that it does not vary beyond a great change in the height level. A guide nipple is mounted on the bottom of the reservoir and extends upwar... | 03/11/1980 |
| 4187262 | Carbonator and liquid level control A carbonator has a pressure vessel, a nozzle for introducing water and carbon dioxide into the vessel, a water level control including a reed switch and a magnetic float for sensing the level of water and operating the reed switch; a novel housing enclose... | 02/05/1980 |
| 4101608 | Oxygen impregnation method An apparatus for dissolving oxygen in a body of water includes a housing submerged in a body of water.
