Patent CA-2769821-A1 (CA)
Inventor: HATZINIKOLAS MICHAEL
IPC: E04B9/22
Filed: 2012-02-28
Abstract: The end of a transversely extending beam is joined to a wall structure by a self-releasing structural assembly. The self-releasing structural assembly has a first portion that is anchored to the wall, typically as a built in connection. A second portion of the assembly sticks out from the wall. This portion is fireproof and non-thermally degradable. It defines a seat for receiving vertical shear loads from the beam. The assembly also includes a thermally degradable member that is keyed to the second portion of the structural assembly. Both portions have slots for accepting the end fasteners of the beam. In normal use the beam fasteners squeeze the end of the beam, the support bracket seat, and the consumable, thermally degradable member in compression. When exposed to heat or flame the consumable, thermally degradable member softens, releasing the tension in the beam end fasteners, and releasing the compression in the structural sandwich of parts. The end of the beam is then able to translate away from the wall structure. The consumable member can be inspected, replaced if necessary, and the beam fasteners re-tensioned, without removing the beam end from the seat.

Abstract: Implementations of the present invention include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. The driven latch mechanism can further include a retracted groove adapted to lock the plurality of wedge members radially within the core barrel assembly, thereby allowing for faster travel within the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems.
