Patent number: 9976370Abstract: A dump bailer actuator mechanism is disposed in a dump bailer having an elongated body and a longitudinal bore therethrough. The actuator mechanism has a collet rod which is moved longitudinally between a first, lower position and a second, upper position, by an electric motor turning a threaded shaft, on which rides a nut assembly connected to a push rod, which in turn contacts the collet rod. In the first, lower position, the collet rod keeps the collet fingers of a collet finger assembly, which have external shoulders, engaged with a shoulder profile within the bore of the main body. A weight bar assembly is attached to the collet finger assembly. When the collet rod is moved to the second, upper position, the collet fingers disengage from the profile, and the weight bar assembly is moved forcefully downward, striking a swab piston and forcing cement out of the dump bailer.Type: GrantFiled: December 22, 2015Date of Patent: May 22, 2018Inventor: Michael Wayne Boleyn, Jr.

Patent number: 9939299Abstract: By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.Type: GrantFiled: January 29, 2016Date of Patent: April 10, 2018Assignee: UNIVERSITY OF WASHINGTONInventors: Shwetak N.

Patent number: 8616237Abstract: A mesofluidic scale digital valve system includes a first mesofluidic scale valve having a valve body including a bore, wherein the valve body is configured to cooperate with a solenoid disposed substantially adjacent to the valve body to translate a poppet carried within the bore. The mesofluidic scale digital valve system also includes a second mesofluidic scale valve disposed substantially perpendicular to the first mesofluidic scale valve. The mesofluidic scale digital valve system further includes a control element in communication with the solenoid, wherein the control element is configured to maintain the solenoid in an energized state for a fixed period of time to provide a desired flow rate through an orifice of the second mesofluidic valve.Type: GrantFiled: February 3, 2011Date of Patent: December 31, 2013Assignee: UT-Battelle, LLCInventors: John F. Jansen, Lonnie J. Love, Randall F. Lind, Bradley S. Richardson

Patent number: 8615329Abstract: A control system is disclosed for regulating the flow of a liquid from a liquid provider through a liquid distribution system. The distribution system has a major liquid distribution channel connected to a plurality of minor liquid distribution channels providing the liquid to a multiplicity of users. A plurality of controllable user valves are interposed in the multiplicity of user channels. A liquid monitor senses a liquid flow characteristic within the liquid distribution channel. A user control changes selective controllable user valves for restoring a desired liquid flow characteristic within the liquid distribution channel.Type: GrantFiled: November 16, 2007Date of Patent: December 24, 2013Assignee: Water Optimizer LLCInventor: Thomas M. O'Connor

Patent number: 8596299Abstract: An externally mounted mechanical device for mechanically closing a pressurized tank or cylinder valve, such as a grill tank, is provided. The device comprises a securing mechanism, a rotatable mechanism having a handle recess to receive a handle of pressurized tank or cylinder valve, and a torsional spring, wherein the torsional spring is configured to store potential torsional force and then release the torsional force by way of a timed release mechanism. The mechanical device comprises a securing device for securing the mechanical device to a tank or cylinder. Torsional force may be stored in torsional spring by way of a ratchet and pawl that also is configured to release the stored torsional force by way of a timed release.Type: GrantFiled: April 1, 2010Date of Patent: December 3, 2013Assignee: Turtle Industries, LLCInventors: Ajay Patel, Alan Kenyon, Arvind A.

Publication number: 20130276898Abstract: A method and a device for supply of a dialyser in a dialysis unit with dialysis fluid is disclosed. At least one dialysis fluid concentrate is mixed with water to produce the dialysis fluid. The dialysis fluid concentrate is prepared in a reservoir unit in a given amount. A control and arithmetic unit calculates the dialysis fluid rate (Qd) such that, after a given treatment time (TB) has passed, a given residual amount of dialysis fluid concentrate or no residual amount remains in the reservoir unit. It is preferable to empty the reservoir unit by the end of treatment.Type: ApplicationFiled: June 14, 2013Publication date: October 24, 2013Inventors: Gerard Remkes, Gerhard Wiesen
