Abstract: An apparatus for producing longitudinally folded products has a machine frame (17) which is arranged below a former arrangement which can be charged with web material. Transporting and processing units are arranged in tandem in the machine frame (17), and a superstructure wall (18) which carries web guiding members (19) associated with the former arrangement is mounted on the machine frame (17). At least one web ribbon (2a) is guided through the superstructure wall (18). The machine frame (17) has at least two modules (22, 23) arranged one above the other which are rotatable by 180° relative to one another and can be connected to one another. Each module (22, 23) has its own at least one drive motor, and every unit provided in the region of the dividing line (24) between modules (22, 23) which are rotatable relative to one another is constructed symmetrically with respect to a center working plane containing the axis of rotation.

Abstract: A sensor holder for a piston-cylinder unit with a cylinder and a piston rod which is movable relative to the latter comprises a holding element which carries out a synchronous movement with respect to the piston rod and has a first position measuring device. A second position measuring device is held by a holder so as to be axially stationary with respect to the cylinder, and there is a rotationally oriented installation position between the first position measuring device and second position measuring device. The cylinder-side holder and the holding element are rotatable relative to one another, and a magnetic force acting between the holder and the holding element brings about a rotational orientation of the two position measuring devices relative to one another.

Abstract: The invention provides for surface mapping of in-vivo imaging subjects using a single camera and an illuminator that projects a plurality of targets such as spots on the subject. By limiting the depth-of-field of the camera lens, or of the illuminator optics, or both, a spatial plane is defined in which the spots are most sharply in focus. Controlled displacement of this plane relative to the subject is achieved through movement of the mechanical stage on which a subject is placed; or through movement of the best-focus plane by adjustment of the camera, lens, or illuminator optics. Images are taken at several relative positions of the best-focus plane and the subject, and the height of individual points on the subject is determined through analysis of focus, given the known displacements. A mesh or other surface can be constructed from individual point locations, to provide a surface map of the subject. Accuracy of 0.5 mm can be readily attained for mice and similarly sized subjects.

The flow guide element has a drive-side end with an axial bearing area which can be moved into axial contact with an axial bearing, which is either an axial contact surface on the drive-side housing wall or is assigned to the drive-side housing wall.

The optical information is in the form of light beams extending from an image generating device (1), over at least one optical element to a surface and the virtual image is visible in front of, behind or in said surface. The light beams produce a beam path. Said invention is characterised in that an optical element (4), which influences beams, is arranged in the beam path between the image generating device (1, 2, 3) and the surface (WS), and that the optical element (4), which influences the beams, is arranged in the position thereof such that it can be modified by means of an adjusting device (5).

Abstract: The device for actuating a pivoting movement of a vehicle flap about a pivot axis includes a gas spring having a cylinder and a piston rod protruding from the cylinder. Either the cylinder or the piston rod is coupled to a fixed component of the vehicle body, and the other one of cylinder and piston rod is coupled to the flap at a distance from the pivot axis. A flexurally rigid guide extends parallel adjacent to the gas spring and is fixedly connected to the cylinder of the gas spring. One region of a flexible tension and compression element is guided in the guide and operatively connected to the flap, and a second region is guided in a flexible casing and operatively connected to a reversible drive, so that the flexible tension and compression element can be motor-driven.

Abstract: An optical filter uses two or more reflective polarizers together with retarders to form birefringent filters with controlled transmission. The energy reflected by these polarizers is absorbed by one or more dichroic elements, which can be adjacent to a reflective polarizer; or spaced apart from it by one or more retarder elements. These dichroic elements act as dampers, so the energy of rays undergoing multiple reflections is markedly reduced or virtually eliminated, and high image quality is maintained. This provides a filter arrangement with enhanced spectral range, image quality, or greater extinction, or lower cost, compared to filters using dichroic or prism-type polarizers.
