Abstract: The present invention relates to a length of pipe with a female end that is reinforced by a band of reinforcing material that extends around the female end. When the pipe and a similar adjacent pipe are threadably connected, the reinforcement material reinforces the female end against failure due to hoop stresses and/or lateral stresses. In this regard, the reinforcing material is any material with a higher resistance to hoop stresses and/or lateral stresses than the material from which the pipe is made. The present invention is also directed to manufacturing processes for manufacturing the pipe of the present invention.

Abstract: A method for magnetizing a wellbore tubular is disclosed. The method includes magnetizing a wellbore tubular at three or more discrete locations on the tubular. In exemplary embodiments the magnetized wellbore tubular includes at least one pair of opposing magnetic poles located between longitudinally opposed ends of the tubular. Wellbore tubulars magnetized in accordance with this invention may be coupled to one another to provide a magnetic profile about a section of a casing string. Passive ranging measurements of the magnetic field about the casing string may be utilized to survey and guide drilling of a twin well. Such an approach advantageously obviates the need for simultaneous access to both wells.

IPC: B23K26/00
Filed: 2011-01-26
Abstract: A circuit assembly controlling an optical system to generate optical pulses is provided.  The optical system includes a seed light source optically coupled to an amplitude modulator. The circuit assembly includes a control circuit which generates a pulsed seed drive signal for driving the seed laser source, as well as logic signals defining successions of ON and OFF states and having a predetermined relative timing relationship. One or more of the logic signals is delayed by a corresponding programmable delay line to adjust the relative timing relationship between the logic signals. A logic gating module combines the logic signals according to one or more logical rule, thereby providing a modulator drive signal. Using this circuit assembly, the optical system outputs an optical pulse at each ON state of the modulator drive signal synchronized with the passage of one of the seed optical pulses through the amplitude modulator.

Title: Safety supervisory module of an electric vehicle charging station
Inventor: HAGENMAIER CARL F JR
IPC: B60S5/00
Filed: 2011-05-16
Abstract: A safety supervisory module (SSM) of an electric vehicle charging station that controls flow of current from the electric vehicle charging station to an electric vehicle. The SSM includes a set of two or more processors to control operation of a contactor control circuitry of the SSM to open and close a set of contacts of a set of power supply lines to control flow of current from the charging station to an electric vehicle. Each processor independently determines whether an unsafe condition exists and asserts a relay enable signal to the contactor control circuitry only when an unsafe condition does not exist. The contactor control circuitry generates a current to energize a relay to close the set of contacts responsive to the relay enable signal being asserted by each and every processor of the set of processors, and inhibits closure of the set of contacts or opens the set of contacts to prevent electricity from flowing between the charging station and an electric vehicle when any of the set of processors is not asserting the relay enable signal.

Title: Shut-off valve
Inventor: DALTON MARTIN WALTER
IPC: F16K31/385
Filed: 2010-02-10
Abstract: This invention relates to a shut-off valve, and primarily to a valve for shutting-off the flow of a fluid such as a mains water supply to commercial premises or a domestic dwelling. The shut-off valve (10) comprises a diaphragm valve and a pilot valve (30). The diaphragm valve has an inlet (14) and an outlet (16), a valve member (26) and a valve seat (22), the valve member having a closed position in which it engages the seat and prevents the flow of fluid from the inlet to the outlet, and an open position in which the valve member does not engage the seat and fluid can flow from the inlet to the outlet. A first fluid conduit ( 36) connects the inlet of the diaphragm valve to the inlet of the pilot valve, and a second fluid conduit (40) connects the outlet of the pilot valve to the outlet of the diaphragm valve. The pilot valve has an open position in which fluid can flow from the first fluid conduit to the second fluid conduit and a closed position in which fluid cannot flow from the first fluid conduit to the second fluid conduit. The invention is characterised in that the diaphragm valve has a control member (42, 44, 46) which is adapted to hold the valve member against the valve seat, whereby the diaphragm valve remains closed even if the pressure at its outlet equals or perhaps exceeds the pressure at its inlet.

Title: Database schema complexity reduction
Inventor: KNIGHT MARK
IPC: G06F17/30
Filed: 2010-04-07
Abstract: In contrast to the traditional approach of defining relationships between data collections using complex groups of cross-reference database tables, the present invention makes use of generic sets to represent relationships between complex collections of interrelated data. The complexity of a database schema can be greatly reduced by representing the relationships between data items as these data sets (sets of data items). These sets of data items may be defined in one or more database tables in a database. This approach provides for much simplified database data management and control. It enables the easy pre- or re- calculation of sets and provides for the easy creation of hierarchical meta-data trees, which are ideal for the targeted delivery of data to the user.
