Abstract: The invention relates to a drilling tool for producing a bore in the ground, comprising a rotatably drivable basic body, a removal means at a lower end of the basic body for removing soil material, and at least one adjustable removal element, which is adjustable between a radially inner retraction position and a radially outer extension position in which the removal element protrudes radially outwards relative to the basic body in order to widen a bore diameter.

Abstract: The invention relates to a drilling tool, in particular for discontinuous earth drilling, with a ground removal means which is arranged in a lower region of the drilling tool and is designed for removing ground material, a receiving space which is designed for receiving the removed ground material above the ground removal means on the drilling tool, at least one passageway which is designed for the passage of the removed ground material from the ground removal means into the receiving space during drilling, a closure means for closing the at least one passageway during withdrawal of the drilling tool from the borehole and a connecting means located in the upper region of the drilling tool for releasable connection with a drill rod.

Abstract: The present invention provides a cover plate for covering at least portions of a door gap formed between a door covering and a fuselage cell of an aircraft or spacecraft, comprising: a fastening portion by which the cover plate can be mounted on an outer surface of the door covering; a contact portion which rests in a contacting manner against an outer skin of the fuselage cell when the door covering is closed; at least one corner portion associated with a corner of the door covering; and a side portion associated with a side of the door covering, the at least one corner portion and the side portion being configured to press the contact portion with a constant contact pressure against the outer skin of the fuselage cell when the door covering is closed.
