US Patent:

58084703, Sep 15, 1998

Filed:

Sep 26, 1996

Appl. No.:

8/719689

Inventors:

Lewis E. Adams - Phoenix AZ
Jeffrey W. Hall - Gilbert AZ

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G01R 3114

US Classification:

324510

Abstract:

A method for detecting ground faults between a community antenna television (CATV) coaxial cable and an appliance coupled to the CATV coaxial cable for receiving CATV broadcasts is provided. A potential difference between a shield of the coaxial cable and a chassis of the appliance is determined. A fault indicator is provided, if the potential difference exceeds a predetermined threshold voltage. An apparatus for detecting ground faults between an appliance and a CATV coaxial cable is also provided. The apparatus includes a comparator. A first input of the comparator is coupled to a chassis of the appliance. A second input of the comparator is coupled to a shield of the coaxial cable. The comparator indicates a fault condition if a potential difference between the first and second inputs exceeds a predetermined threshold.

Abstract:

A method for separating lighter components of a hydrocarbon product in a container tank includes introducing the hydrocarbon product into the container tank via an inlet located near or at the bottom of the container tank; routing the hydrocarbon product through a pipe-in-pipe conduit that is at least partially surrounded by a bulk fluid stored in the container tank; providing a vapor-liquid interface that allows efficient evaporation of the lighter components resulting in separation of the lighter components and a processed hydrocarbon product; and routing the processed hydrocarbon product into the annular space of the pipe-in-pipe conduit thereby thermally insulating incoming hydrocarbon product from the surrounding bulk fluid and eliminating or minimizing vapor liquid equilibrium shift of the incoming hydrocarbon product caused by increased head pressure and/or reduction in temperature of the incoming hydrocarbon product.
