Appl. No.:

13/584503

Inventors:

Robert Terrence McHugh - San Diego CA, US
Errol F. Jacob - Cleveland Heights OH, US
Daniel Matthew Wilbers - San Marcos CA, US

Assignee:

INVENSYS SYSTEMS, INC. - Foxborough MA

International Classification:

G01M 3/28
G06F 19/00

US Classification:

702 51

Abstract:

A method for detecting a leak in a fluid conducting conduit is disclosed. Inlet and outlet flowrates are measured for calculating a time derivative of average temperature of the fluid flowing in the fluid conducting conduit. A predicted difference in flowrate between a flowrate of fluid in the fluid conducting conduit adjacent the inlet and a flowrate of fluid in the fluid conducting conduit adjacent the outlet is calculated based on the calculated time derivative of the average temperature of the fluid flowing in the fluid conducting conduit. The predicted difference in flowrate is compared to a difference between the measured inlet flowrate and the measured outlet flowrate to determine whether a leak exists in the fluid conducting conduit.

Assignee:

Hon Hai Precision Ind. Co., Ltd. - Taipei Hsien

International Classification:

H01R 13625

US Classification:

439341

Abstract:

A board-to-board connector block for horizontally and electrically engaging a secondary board with a source board includes an insulative housing defining a plurality of passageways therethrough for receiving a corresponding plurality of resilient contacts therein, positioning means for properly aligning the connector block onto the source board, a U-shaped lever pivotably engaged with the housing, stabilizing means for holding the lever in place when in a locked position, and fastening means for securing the lever onto the housing. A force from the lever acting on the resilient contacts of the connector block results in a reactive force from each contact acting on a corresponding contact pad of the source board thereby securely and electrically engaging the two boards together.

International Classification:

H01R 450

US Classification:

439342

Abstract:

A ZIF socket includes a cover slidably engaged with a base to which a cam is pivotably connected. The cam is selectively rotated in a clockwise or counter-clockwise direction thereby driving the cover to move laterally in opposite directions with respect to the base. The rotational plane of the cam is substantially parallel to the plane of movement of the cover.
