Abstract: An adjustable width mold apparatus for a slipform paver includes a center portion and left and right sideform assemblies. The left and right sideform assemblies are movably mounted on a machine frame. Left and right actuators can independently move the left and right sideform assemblies relative to the machine frame. A mold width of the mold is adjustable without adjusting a width of the machine frame. The mold can be laterally shifted in position relative to the machine frame.

Abstract: A self-propelled paving machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. The machine may be re-oriented from a paving mode to a transport mode by driving the ground engaging units to rotate the frame substantially in place on the ground through a re-orientation angle of the frame relative to the ground, and as the frame is rotating, pivoting one or more of the swing legs from a paving position relative to the frame, to a transport position relative to the frame.

Abstract: A self-propelled paving machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. The machine may be re-oriented from a paving orientation to a transport orientation via a transport conversion mode of an automatic controller configured to spin the paving in place on the ground through a re-orientation angle, then rotate each of the crawler tracks relative to its respective swing leg until each crawler track is primarily oriented in a transport direction generally perpendicular to the paving direction, and then while moving the paving machine in the transport direction pivoting each of the swing legs relative to the frame until each swing leg is oriented primarily in the transport direction. The paving machine may then be driven onto a transport vehicle.

Abstract: An apparatus and method for isolating a downhole tool section from hydraulic and mechanical noise. Anchoring grippers are used in conjunction with a fluid diverter valve to anchor the tool section to a borehole wall and divert fluid flowing in the drill string away from sensitive test equipment during formation testing.

Abstract: An in-situ rock strength measurement tool features a sub that is integrated into a drill string, or other downhole tool string, and lowered into an uncased borehole. The sub includes a plurality of lateral pistons that are selectively extendable in a radial orientation to engage the wall of the borehole. The pistons exert a force against a defined area of the borehole wall and penetrate the borehole across the defined area. The force needed to penetrate the borehole may then be measured and used to calculate rock strength and to determine other formation properties.
