Abstract:
The invention concerns a shutter system designed for a shutter (4) mounted on a vehicle body so as to be mobile relative thereto. The invention is characterized in that the shutter is maintained at least at one of its two lateral ends by a quadruple hinge mechanism formed by two main hinge elements (10, 12) which are mounted pivotable on the body (8), and a linking hinge element (16) which links together the free ends of the main hinge elements; and an adjusting motor (22) is mounted on the shutter itself, to move at least one of the quadruple hinge mechanisms. According to the invention, at least one main hinge element (10) of one quadruple hinge mechanism, is secured to the shutter or is a component of the shutter, and the linking hinge element (16) is pivotable relative to the adjusting motor means (22).
Abstract:
A radial anti-friction bearing, which has an outer and inner bearing race with an inner and outer raceway and cylinder rollers that roll on the raceways between the bearing races and which are held at equal distances to each other in the peripheral direction by a bearing cage. To prevent slip, the cylinder rollers are replaced by hollow rollers, which have a larger outside diameter and lower modulus of elasticity. The dimensions of the bearing races, cylinder rollers and hollow rollers are configured such that both the cylinder and hollow rollers initially have a defined radial bearing clearance in the non-installed state of the radial anti-friction bearing, and the pretension necessary for the continuous drive of the bearing cage is adjusted on the hollow rollers only once the radial anti-friction bearing has been installed, while simultaneously reducing the radial bearing clearance at the cylinder rollers.
Abstract:
A device for opening and/or closing a pivoting body piece (14), especially a rear hatch, of a motor vehicle (10). The device has an electric motor drive (20) which drives a motor shaft which drives the pivotable body piece (14) via a gearing (22). In order to enable the device to have a clutch-free structure, the electric motor drive (20) is provided, in accordance with the invention, with an electronic isolation means (24) which can be activated depending on a signal from a sensor means (30) which recognizes manual actuation of the pivoting body piece (14).

Abstract:
According to one exemplary embodiment of the present invention, a method for sensing the position of an edge of a stock being feed to a printing press is provided. The method includes the steps of providing a light source, utilizing the light source to illuminate with planar radiation a preselected area of the stock, and a preselected area adjacent to the stock, and further providing a retro-reflecting surface on at least a portion of the preselected area adjacent to the stock illuminated by the light source. According to a feature of the present invention, a measuring device is provided and utilized to measure radiation reflected by the retro-reflecting surface.
Abstract:
A radial roller bearing for storing shafts in wind turbine transmissions, which has an external bearing ring with an inner runway, an internal bearing ring arranged coaxial thereto provided with an external runway, and a plurality of roller bodies that displace on the runways between the hearing rings held at regular intervals by a bearing cage. To prevent slip, the roller bodies are replaced by hollow rollers that have a greater diameter and a smaller elasticity module than the roller bodies ensuring, when the radial roller bearing is in the load-free state, permanent contact with the bearing rings, a permanent drive of the bearing cage and that the roller bodies have kinematic rotation. The hollow rollers have a higher bending strength, and their internal cover surface has a maximum surface roughness of Rz≦25 μm preventing localized peaks of tension, without any disaggregation in the axial direction.

The hollow rollers, by a defined dimensioning of their internal diameter in relation to their external diameter for the dimensioning of the radial roller bearing, have the same bearing capacity as the roller bodies.
Abstract:
A sheet sensor arrangement for a sheet printing machine and particularly for a turning device of a sheet printing machine, which comprises at least one hollow cylindrical drum (3; 4), which has a gripper system to transport and/or temporarily store individual sheets (5). A sensor arrangement which is not very susceptible to contamination and has a mechanically simple structure is comprised of the fact that the cylindrical wall of the drum (3; 4) has at least one opening which allows light to pass through, and that a sheet sensor is formed by a light barrier (9, 10, 11), which has a light beam which, in at least one angle position of the drum, is directed from the inside at the opening which allows light to pass through. In addition, a corresponding process for optical monitoring of sheets in a sheet printing machine is indicated.
