| 7195229 | Automatic sampler In a direct injection type automatic sampler, a sampling needle having a liquid sample collected from a sample vessel by using suction force of a pump is inserted into an injection port. Then, a flow path-switching valve is rotated to switch a flow path to make a fl... | 03/27/2007 |
| 7063302 | Sample valve with integral sample shut off function for chromatograph A multiple port valve integrated with the function of the sample shut off valve is disclosed. The integration of the sample shut off function eliminates extra plumbing and labor costs associated with a separate sample shut off valve. Additionally, the multiple port ... | 06/20/2006 |
| 6973938 | Liquid column pressure and vacuum vent A pressure and vacuum vent utilizing a column of liquid to open and close the vent at predetermined pressure and vacuum levels. A column of liquid is constrained in connection with internal and external passages coupled between a pair of expansion chambers. The exte... | 12/13/2005 |
| 6858150 | Water processing device with liquid seal A water processing device for removing contaminants from water for consumption, consisting of: 1) a heat exchanger; 2) a heater; 3) a boiler chamber; 4) a liquid level control device; 5) a demister; 6) a degasser; and, 7) a self-cleaning component. A water seal to p... | 02/22/2005 |
| 6823785 | Printing unit A printing unit has at least four cylinders that form a printer. At least two of these four cylinders rotate independently of each other. At least one of the cylinders in the group of at least four cylinders has a set up rotational speed that is not zero and that is... | 11/30/2004 |
| 6655657 | Coking-resistant bearing An EGR valve for use in an engine includes a valve body defining an internal passage for the passage of exhaust gas through the valve and a bearing supported in the passage having a bearing surface including an end portion adjacent to the internal passage... | 12/02/2003 |
| 6638481 | Plug flow cytometry for high throughput screening and drug discovery An apparatus for drawing and supplying multiple samples for rapid processing in flow cytometry. The apparatus comprises a reciprocating valve and at least one syringe. The invention is also a method for rapidly processing multiple samples in flow cytometr... | 10/28/2003 |
