Abstract: A locking device is provided for locking two structural parts that are moveable relative to each other. A latch hook is disposed in a reference plane and is adapted to swivel on a joint with an axis center. An actuating element is provided for swivelling the latch hook about a latch hook axis. A rocking lever interacts with the actuating element for rotation about a rocking lever axis. The lever is connected with a first end of a steering arm via a first rotary joint. A second end of the steering arm is connected with the latch hook via a second rotary joint.

Abstract: A fluid actuating drive for relative translational movement of first and second structural parts has a housing filled with a pressurizing medium, which in its longitudinal direction, runs along a gap that separates the structural parts, and is connected therewith. The width of the gap is dependant upon the relative position of opposing side walls of the housing, which side walls can be moved against one another with a pressurizing agent for the relative movement of the structure, where the side walls are alternately connected to the first and second structural part across the gap.

Abstract: A variable wing section having an adjustable profile shape extending in the wing-span direction, includes a plurality of torsion boxes, which are positioned in the longitudinal direction, are torsionally stiff about the wing-span direction, and are each constituted of a first wing skin, a second wing skin opposite to it, and at least one spar. The variable wing section includes at least one vertebra, which has a transmission element that is connected to the first wing skin by a pendulum joint in order to compensate for a relative movement between the first wing skin and the at least one vertebra, and which has a vertically spaced-apart point of connection to a drive chord, the length of which may be changed, using a control command. The length of the drive chord is changed as a function of a control signal, and the at least one vertebra is rotated about the wing-span direction, so that the shape of the torsion boxes, and thus the profile shape, are changed in a predetermined manner.

Abstract: Method and apparatus for the contactless monitoring of a working tool for breakage or wear, the tool being installed in a machine having at least two parts, with one of the parts being stressed by forces imposed on the working tool during machine operation, by: inductively monitoring the position of the one part relative to the other of the two parts during machine operation to produce at least one induced voltage representative of a change in relative position; determining the value of the induced voltage; and emitting a signal when a predetermined change occurs in the value of the induced voltage.

Abstract: The specification discloses an adjustable motor mount enabling rapid movement of a motor to allow easy removal and proper tensioning of a drive belt. The motor mount moves relative to a supporting framework by means of a cable coupled to a cable take-up means.

Abstract: The luggage case construction has a first open sided shell over which a cover is removably secured. The shell includes bottom, top and two end walls interconnected by a rectangular back wall. An elongated frame member extends continuously along the inner top wall surface, both end walls and for a distance inwardly of the end walls onto the bottom wall. The frame is centrally located within the shell and includes a pair of parallel rib-like elements integrally related by a wall portion via which it is riveted to the luggage case shell. At each of the corners of the luggage case sheel and in the central portion immediately under the handle of the top wall there are provided sheet-like elements between the channel and the luggage case walls. The sheet-like members extend transversely of the luggage case an amount equal to the total case width, such that when the cover is closed over the shell and the secured in place, the sheet-like member establishes a firm case width.
