Abstract: A method utilized in borehole logging, such as in surveying or exploration relating to a subsurface formation. The method includes deploying a logging instrument that includes a pressure sensor into a borehole drilled into the formation. The method includes the steps of obtaining a first pressure value at a first depth in the borehole, obtaining at least one further pressure value subsequent to the first pressure value during withdrawing or advancing the logging instrument in the borehole, and determining one or more characteristics of the subsurface formation, utilizing at least one of the further pressure values, or a change in pressure (??) between the first pressure value and a said further pressure value or values, or a change in pressure (??) between a said further pressure value and another said further pressure value, or a combination of two or more of such values.

Abstract: An array of induction magnetometers for use in airborne transient electromagnetic (ATEM) geophysical exploration is disclosed, having similar weight and external dimensions of prior art induction magnetometers but with improved signal strength, signal-to-noise ratio, higher frequency, self-resonance and bandwidth, and providing accurate and well monitored calibration.

Abstract: A manufacturing cell having a plurality of work stations, where at least one of the work station comprises a metalworking machine, and where at least one metalworking machine is provided with a modular tooling apparatus. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine.

Abstract: A modular tooling apparatus for performing a metalworking operation on a workpiece or a family of workpieces. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine. The modular tooling apparatus permits machining a family of workpiece members that are related but different in detail, by inserting the insert member from the family of inserts to properly position and orient the corresponding workpiece member, without needing to change, disconnect, or move the base tooling.

Abstract: A modular tooling apparatus for performing a metalworking operation on a workpiece, having a base comprising an attachment surface having a locating feature, a removable insert separably secured to the attachment surface, having a locating feature and a workpiece support feature on a surface thereof, and an extraction/locking device movable between a first position wherein the insert is secured to the attachment surface, whereby the locating feature of the insert associates with the locating feature of the attachment surface, and a second position wherein the insert is at least partially extracted from the attachment surface. The extraction/locking device alternately secures an insert to the base and assists in extracting the insert from the base. The device provides for ease of removal of an insert when the upper portion does not provide convenient surfaces for a technician to grab.
