This automaton for applying a patch to a draping surface (15) comprises a gripper (24) capable of grasping the patch and depositing it on the draping surface (15), and a heating system (25) for directly heating the draping surface (15).

A method eliminates voids in the bond line and manipulates a thickness of the bond line. This method includes: applying an adhesive at a center of an area of a structure; placing a doubler on the adhesive over the area of the structure, wherein the doubler has a peripheral edge; and maintaining a negative pressure at the peripheral edge of the doubler while simultaneously maintaining a positive pressure at the doubler to purge entrapped gases and control a thickness of the bond line at the peripheral edge of the doubler.

A device includes a water storage tank, a control cabin and an operation cabin which are sequentially connected from top to bottom, the operation cabin includes a sealing zone and an operation zone, the sealing zone is located on an inner wall of the operation cabin, a pressure difference between an internal pressure and an external pressure is adjusted to make the maintenance enhancing device separated from or absorbed on a subsea pipeline, and the operation zone is located between the sealing zone and the subsea pipeline.

An installation tool and method are provided to apply a patch to a structure while controlling the porosity in the bond line. An installation tool is provided that includes a frame defining an internal cavity. The installation tool also includes a flexible membrane that divides the internal cavity into a first chamber proximate the surface and a second chamber separated from the surface by the first chamber and the flexible membrane. The flexible membrane is releasably attached to the patch such that the patch faces the surface. The frame includes first and second vacuum ports into the first and second chambers, respectively, such that pressure therewithin is separately controllable. The pressure within the first and second chambers is controlled such that the adhesive is degassed while the patch remains spaced from the surface and the flexible membrane is thereafter caused to be stretched to urge the patch toward the surface.

A filling method for filling surface imperfections on a surface of a wing comprising a scanning step in which a control unit controls a movement of a scanner past the surface of the wing to scan the surface and transmit the collected data to the control unit, a computation step in which the control unit computes a digitized surface from the data, a determination step in which the control unit determines each surface imperfection by comparing the reference surface and the digitized surface, a generation step in which the control unit generates a digital model of the patch intended to fill the surface imperfection, and a printing step in which the control unit controls the movement of a 3D printer past each surface imperfection and commands the activation of the 3D printer in order to make it print the patch.

A foldable tool kit includes: a main body having a first side board and a second side board spaced from each other; multiple tools including a grinding tool, a chuck and a blade, one end of the tools being pivotally connected with at least one end of the main body and rotatable; the other end of the chuck having a chuck section; a grinding section being disposed on the grinding tool; and at least one tire reparation member received in one of the side boards. In case that a tire is punctured, the foldable tool kit can be used to repair the tire.
