Abstract: An apparatus (10, 60) for storage of elongate elements, such as pipes, tubes and conduits. The apparatus (10, 60) includes a frame (12) that supports a plurality of trays (15, 63). The trays (15, 63) are arranged in two vertical columns of storage positions, except for the trays located at the top or bottom of the apparatus as they are moved about sprockets (71, 72) by a drive motor (73). Each tray (15, 63) is configured to support a plurality of elongate items. The trays (15, 63, which may embodied as cradles or racks, may be moved between a storage position and an access position, wherein in the access position, the elongate items can be accessed from substantially vertically above the tray (15, 63).

Abstract: A gate opening and closing assembly includes a mount that is coupled to a vertical member of a gate that is extendable across an entry way. A drive unit is coupled to the mount and the drive unit is actuated to rotate in a first direction or a second direction. A wheel is rotatably coupled to the drive unit to roll along the ground. The wheel is rotated in an opening direction when the drive unit rotates in the first direction to urge the gate into an open position thereby facilitating a vehicle to drive through the entry way. The wheel is rotated in a closing direction when the drive unit rotates in the second direction to urge the gate into a closed position thereby inhibiting the vehicle from driving through the entry way. A remote control is in wireless electrical communication with the drive unit. The remote control turns the drive unit on and off to open and close the gate.

Abstract: An airfoil with dual wall cooling for a gas turbine engine comprises a spar having pressure and suction side walls that meet at leading and trailing edges of the airfoil, with a tip extending therebetween. An interior of the spar includes a coolant cavity, and each of the pressure and suction side walls includes an arrangement of pedestals on an outer surface thereof and a plurality of cooling holes in fluid communication with the coolant cavity. A pressure side coversheet overlies the pressure side wall and terminates in a radial direction short of the tip of the spar to form a shelf extending along a chordal direction. Flow channels between the pressure side wall and coversheet are configured to direct coolant from the cooling holes to radial flow outlets adjacent to the shelf. A suction side coversheet overlies the suction side wall, and a coolant circuit between the suction side wall and coversheet does not include radial coolant outlets.

Abstract: Techniques to facilitate assignment and scheduling of activities. In accordance with a method, a chart showing a calendar of schedule for a number of available resources is provided in a first frame (or window) in a user interface menu, and a number of objects representative of a number of unplanned activities are provided in a second frame. A selection for an unplanned activity in the second frame (or a planned activity in the first frame) is received and, in response, selected ones of a number of objects in the chart are highlighted based on the selected activity. A request to assign the selected activity to a selected resource and to schedule the selected activity for a particular time duration is thereafter received. The requested assignment and scheduling may be accepted or rejected based on the requirements of the selected activity and the capabilities of the selected resource.
