Patent number: 10345186Abstract: A device comprising a pressure monitor and a control means that receives a signal representing measured pressure at the pressure monitor and controls the controllable elements of a fluid system is utilized to monitor a fluid system for error conditions, to optimize operations and to diagnose the fluid system. By following a testing protocol that selectively enables parts of the system, the control means narrows the list of possible falling components. Comparing the measured pressure against normal pressures allows the device to identify error conditions. Determining the volume of fluid being transported and controlling the duration of the flow optimizes operation of the fluid system.Type: GrantFiled: August 18, 2017Date of Patent: July 9, 2019Assignee: WATERS TECHNOLOGIES CORPORATIONInventors: Theodore D.

Patent number: 9618128Abstract: The present invention provides a method and apparatus for substantially eliminating destructive transients of pressure or flow rate which can degrade the efficiency and useful lifetime of chromatography columns. The present invention enables a substantially constant flow of mobile phase liquid to be maintained through the chromatography system by eliminating the flow blockage interval associated with the actuation of sample injection valves. The present invention further provides a method to reduce the pressure and flow rate transients associated with pressurization of the sample loop contents when the sample loop is introduced to chromatography system delivery pressure.Type: GrantFiled: October 31, 2014Date of Patent: April 11, 2017Assignee: Waters Technologies CorporationInventors: Theodore A.

Patent number: 9435775Abstract: A fluid switching valve includes a first valve element (e.g., a stator) that has a plurality of first fluid-conveying features (e.g., ports), and a second valve element (e.g., a rotor) that has one or more second fluid-conveying features (e.g., fluid conduits in the form of grooves). The second valve element is movable, relative to the first valve element, between a plurality of discrete positions such that, in each of the discrete positions, at least one of the one or more second fluid-conveying features overlaps with multiple ones of the first fluid conveying features to provide for fluid communication therebetween. At least one of the first valve element and the second valve element includes a recess. The recess serves to reduce wear between the first valve element and the second valve element. The recess is arranged such that it does not overlap with any of the first fluid-conveying features or any of the second fluid-conveying features when the rotor is in any of the discrete positions.Type: GrantFiled: February 3, 2012Date of Patent: September 6, 2016Assignee: Waters Technologies CorporationInventors: Mark W.

Patent number: 7955059Abstract: In various embodiments a fluid control device suitable for high pressure analytical instruments includes a housing having an interior surface with an end wall. The interior surface defines a chamber. A valve assembly disposed in the chamber controls the flow of fluid through the chamber. An end cap is disposed in the housing opposite the end wall to enclose the chamber. The end wall and end cap each have an opening to pass a fluid to the chamber or to remove a fluid from the chamber. The housing and end cap each has an abutment surface to receive the other abutment surface. At least one of the abutment surfaces has a plastic seal coating. A means of compression, such as a compression housing and compression sleeve, is included to engage the end cap to deform the plastic seal coating between the abutment surfaces and thereby seal the chamber.Type: GrantFiled: March 2, 2005Date of Patent: June 7, 2011Assignee: Waters Technologies CorporationInventors: Theodore D.
