Abstract: The application describes a tool comprising a tool head and a handle. An end of the handle is connectable to the tool head. The handle comprises a bistable reelable composite member having a first stable form in the form of an elongate slit tube in which form the member is resiliently biased and acts as a handle when connected to the tool head. When separated from the tool head, the tube can be opened out at the slit at an end and progressively coiled around an axis transverse to its length to reversibly attain a second stable form in the form of a coil. Thus, the tool can assume a compact form for storage or transportation.

Abstract: Techniques for live location sharing are described. A first mobile device and a second mobile device can communicate with one another using an IM program. The first mobile device can receive a user input to share a location of the first mobile device in the IM program. Sharing the location can include causing the second mobile device to display a location of the first mobile device in an IM program user interface on the second mobile device. Duration of sharing the location can be user-configurable. The second mobile device may or may not share a location of the second device for display in the IM program executing on the first mobile device.

Abstract: The present invention relates to a device for gripping a flat structure with openings in the area of its upper side, in particular a honeycomb structure, comprising two gripper units spaced apart from each other in a length direction, each of which in turn comprises at least one pin, and at least one pin displacement unit which is adapted to displace the at least one pin in an extending direction, as well as a tilting unit which is adapted to tilt at least one of the gripper units about a tilting axis extending substantially in a width direction.

Abstract: A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

Abstract: A paving machine including a modular frame, a plurality of swing legs pivotable relative to the frame, a jacking column secured to each swing leg, a crawler track, a slew gear drive, and angular position transducers for measuring an angular position between the swing leg and the modular frame, and an angular position of the crawler track relative to the jacking column. Feedback from the transducers facilitates maintaining position of the crawler track. The jacking column can include telescoping outer and inner tubes, a vertically oriented hydraulic actuator including a cylinder and a piston operable within the outer and inner tubes, and spaced apart axial bearings coupled to the outer tube and/or the inner tube. The slew gear drive can be secured between the inner tube and a yoke and capable of steering the crawler track under load without lifting the crawler track.

Abstract: In conventional wireline intervention shifting service, the success of the operation is heavily dependent on the engineer’s experience and knowledge. Any wrong judgement in the process of operation could lead to non-productive time or even total failure. Once the operation is completed, the post-job processing and report preparation also require significant manual effort and are extremely time consuming, which often leads to the inadequate or incomplete report. These challenges are addressed by the advanced surface acquisition software presented in this paper. The aim of the surface software is to redefine the selective shifting workflow by leveraging the available instrumentation, streamlining and simplifying operation procedures, eliminating or reducing the typical human errors observed earlier, and greatly reducing the burden on the field engineers for post-job deliverables with automated real-time data collection, processing, and report generation.

Abstract: A swing leg assembly, coupled to a paving machine for spreading, leveling and finishing concrete, includes a pivotable swing leg coupled to the paving machine. The swing leg may pivot between multiple angular orientations relative to the paving machine. A jacking column is coupled to the swing leg, and a crawler track is coupled to the jacking column. A slew drive coupled to the jacking column and crawler track rotates the crawler track relative to the jacking column between multiple angular orientations. A processor using sensors determines the angular positions of the swing leg and crawler track, and in response to determining a change in angular orientation of the swing leg controls the slew drive to cause the crawler track to rotate relative to the jacking column.
