Abstract: A drill-elastic and flexurally rigid rod element (10) for supporting and guiding a movable flap (24) relatively to a wing (26) of an aircraft, wherein the rod element encompasses a cross-shaped profile cross section and first and second fastening sections (20, 22) and is made of a fiber composite material and the rod element can be fastened to the wing in a fixed manner via the first fastening sections (20) and to the flap (24) via the second fastening sections (22). The rod element and the fastening sections are laminated from a plurality of unidirectional, preimpregnated fibrous layers—prepreg layers—which are bonded to one another in the area of the fastening sections as well as in the cross-shaped cross section core area (28) and which are separated from one another in each case by a separating film inserted between the prepreg layers outside of the areas.

The first and second sections are formed by a strap made of a fiber composite material.

Abstract: An apparatus for producing a holding or transmission frame (12, 20) for an electrostrictive actuator, in particular, a stacked piezoactuator (5) includes the following steps: a) a winding spindle (52), corresponding to the shape of the inner periphery of the frame (12, 20), is wound with several layers of a unidirectional prepreg for forming a laminate body; b) the laminate body is hardened; c) the hardened laminate body in the frame is cut by sections parallel to the direction of winding.

Abstract: A friction wheel singler for singling bank notes includes a singler roller 1 with grooves 2, and retaining wheels 14 cooperating with the grooves 2. The retaining wheels 14 have friction areas 14a and sliding areas 14b such that both a sliding area 14b and a friction area 14a cooperate with each groove 2 of the singler roller 1. Such a friction singler is particularly suitable for longitudinal singling of narrow bank notes and prevents skewing of the sheet to be singled during the singling process.

Abstract: A friction wheel singler is proposed for singling sheet material, in particular bank notes, comprising sheet magazine 5 for receiving stack of sheets 1, singling cylinder 2 having one or more friction elements 4 for contacting and conveying sheet 1a to be singled out of the magazine, and retaining device 3 forming with singling cylinder 2 singling gap 7 through which sheets 1a to be singled out of the magazine are conveyed one by one, retaining device 3 having one or more friction areas 3a for contacting sheets 1a to be singled out of magazine 5.

Abstract: A cog belt pulley defining an axis of rotation having an outer circumferential surface oriented about the axis of rotation and including a plurality of teeth for engagement with at least one cog belt. The pulley is distinguished in having at least one flange segment radially extending from the outer circumferential surface. Each flange segment projects about a fraction of the circumferential surface and is located on an individual plane. The at least one flange segment is arranged for enabling a cog belt to be configured onto the pulley without interfering with the at least one of the flange segment.

Abstract: The present invention relates to a bank note sorting apparatus. Known such apparatuses have the disadvantage of not being user-friendly since the transport path of the bank notes is not readily accessible to a user due to the elaborate mechanical design of the transport system. Bank notes that block the transport system due to faulty transport can therefore not be readily removed. In the present invention this disadvantage is avoided by the bank note sorting apparatus consisting of at least three parts, with one part disposed in the middle and at least two parts removable therefrom, thereby obtaining easy access to the transport system.

Abstract: In a sheet-processing apparatus, banknotes are separated by a separator (10) and fed to a depositing arrangement (18) via a sensor and transporting unit (8). Depositing takes place in different depositing compartments in accordance with depositing criteria which are determined by certain features of the banknotes (BN) being sensed. The individual depositing compartments (30, 32, 34) of the depositing arrangement (18) are assigned stacker wheels (20, 22, 24), which have stacker fingers which, in pairs, define a sheet compartment between them. The banknotes are introduced into the sheet compartments and are then deposited in the associated depositing compartment by the stacker fingers.

Abstract: A rotor blade arrangement includes a rotor blade with a hollow blade chamber therein, and a flap module removably arranged and secured in the blade chamber. The flap module includes a module housing received in the blade chamber, an actuator arranged in the housing, a flap pivotably arranged at an edge of the housing, and a power transmission linkage connecting the actuator to the flap. The module housing is inserted through an opening into the blade chamber, so that the flap protrudes and forms a continuation of the aerodynamic contour of the blade. The flap may be a trailing edge flap at the trailing edge or a leading edge nose flap at the leading edge of the blade. The flap module does not change the center of gravity of the blade. The entire flap module can be easily removed from the blade for adjustment, inspection, maintenance, repair or replacement.

Abstract: A cog belt pulley system includes cog belt pulleys (10a to 10c) each with at least one flange (15 to 17) protruding in the radial direction beyond the toothed circumferential surface (11) and extending in the circumferential direction to limit slipping of the belt (20, 30, 40) at right angles to the circumferential direction of the pulleys (10a to 10c). Said flange is provided only as a segment over a limited part of the circumferential surface in the circumferential direction of the pulleys. A belt is mounted on two pulleys by the pulleys being rotated into a position in which the particular flange segments face each other. In this position the belt can be pushed onto the pulleys without colliding with the flange segments.
