US Patent:

6882924, Apr 19, 2005

Filed:

Oct 6, 2003

Appl. No.:

10/680617

Inventors:

Nathan Todd Miller - San Diego CA, US

Assignee:

Precision Engine Controls Corp. - San Diego CA

International Classification:

G01H003/00

US Classification:

701100, 477 30

Abstract:

A turbine valve control system is provided. The turbine valve control system includes a variable flow metering device, a first sensor, a second sensor, a third sensor, a fourth sensor, memory, and processing circuitry. The variable flow metering device is capable of meeting a plurality of predetermined mass flow rates by varying positioning of the flow metering device. The first sensor is configured for detecting variable positioning of the flow metering device and generating a first output signal that is a function of the positioning of the flow metering device. The second sensor is configured for detecting fluid pressure upstream of the flow metering device and generating a second output signal that is a function of the detected upstream fluid pressure. The third sensor is configured for detecting fluid pressure downstream of the flow metering device and generating a third output signal that is a function of the detected downstream fluid pressure. The fourth sensor is configured for detecting temperature upstream of the flow metering device and generating a fourth output signal that is a function of the detected temperature.

Appl. No.:

11/080063

Inventors:

Nathan Todd Miller - San Diego CA, US

Assignee:

Precision Engine Controls Corp. - San Diego CA

International Classification:

G01H 3/00

US Classification:

701100, 477 30

Abstract:

A turbine valve control system is provided. The turbine valve control system includes a variable flow metering device, a first sensor, a second sensor, a third sensor, a fourth sensor, memory, and processing circuitry. The variable flow metering device is capable of meeting a plurality of predetermined mass flow rates by varying positioning of the flow metering device. The processing circuitry is configured to receive the signals, determine whether the flow is subsonic or sonic, and implement a corresponding one of the first and second computer program codes to calculate a combined coefficient of discharge times area that will generate a desired mass flow rate for the flow metering device. A method is also provided.

Appl. No.:

10/429092

Inventors:

E. Mares - Del Mar CA, US
Nathan Miller - San Diego CA, US
Mark Huebscher - San Diego CA, US

International Classification:

F16K037/00

US Classification:

137/554000

Abstract:

A metering valve for industrial gas turbine engines includes a valve body, a flow tube, an orifice plate, a central flow body, and a mover. The valve body has an inlet and an outlet. The flow tube is carried for axial movement in slidable and sealing engagement with the valve body at an inlet end and an outlet end. The orifice plate has an outlet. The central flow body is provided on an upstream end of the orifice plate and has an annular seal configured to seat into engagement with the outlet end of the flow tube when the flow tube is moved to a downstream position. The central flow body also includes a central, protruding flow diverter upstream and central of the annular seal. The mover is provided in the valve body and is configured to carry the flow tube for displacement of the output end toward and away from the central flow body.

International Classification:

B63G 9/02
B63C 1/12

Abstract:

A device for capturing underwater vehicles. The device comprises a cap member connected to a first rib member and a first plate member connected to the first rib member. The device further comprises a bell member with a first bell hole formed therethrough. The first bell member also has a first bell slot formed therethrough. A damper and a shim are slidably received in the first bell slot. The first rib member is slidably received in the first bell hole.
