Abstract: A flexible surface element is arranged on a vehicle to form a trampoline-like extendable or stretchable receiving or retrieval surface for drones. For this purpose, the surface element is brought out from a gathered-in, folded or pivoted-inward stored, stowed position into a mounted expanded position by means of extendable retention and guidance elements.

Abstract: A writing implement having at its front end a small writing tube and a writing wick axially slidable in it. The writing wick at its inner end has an enlarged head which engages a restoring spring. The restoring spring is part of a retaining ring which holds the spring in the implement, and the retaining ring has capillary ducts to convey ink between ink-conducting passages and the writing wick.

Abstract: There is provided a support structure for a motor. The motor includes a stator and a rotor. The Stator is comprised of a generally plate-shaped winding arrangement including a generally plate-shaped winding support arrangement connected to and supported by the support structure. The winding arrangement further includes a plurality of windings supported on the generally plate-shaped winding support arrangement. The stator further comprises a central support portion supported by the plate-shaped winding support arrangement. The rotor comprises a rotor shaft supported on the central support portion and extending transversely to the generally plate-shaped winding arrangement. The rotor further includes permanently magnetized material and magnetic return structure mounted on the rotor shaft for rotation therewith. Preferably, the motor is supported exclusively by the support structure, with the support structure being connected exclusively to the generally plate-shaped winding support arrangement of the motor.
