Abstract: Adjusting device for a front lid, with an actuator for raising the rear edge of the front lid, wherein the actuator is configured as a coupling mechanism having a first drive with a rotation-locked lever connected to a push rod in an articulated fashion and a second drive with a rotation-locked lever connected to a push rod in an articulated fashion, wherein the two push rods have a common attachment point, via which they are connected to the front lid.

Abstract: Adjusting device for a front lid, with an actuator for raising the rear edge of the front lid, wherein the actuator has a first linear drive which enables a substantially vertical movement of the front lid and a second linear drive which enables a substantially horizontal movement of the front lid.

Abstract: Adjusting device for a front lid with an actuator for raising the rear edge of the front lid, wherein the adjusting device has a front-lid-mounted leg with a guide and a vehicle-body-mounted retaining element with a section guided the guide, wherein the guide of the front-lid-mounted leg is movable relative to the section of the retaining element by the actuator for raising the rear edge of the front lid.

Abstract: An adjustment device for a lock of a front hood of a motor vehicle, with the front hood being movable from a normal position to an elevated position, includes a guide and a carriage which is coupled with the lock and movable along the guide. At least one wedge is configured to clamp the carriage with the guide in a clamping position. An actuating mechanism is provided to allow movement of the carriage from the clamping position to an unclamped position by displacing the at least one wedge.

Abstract: A method for investigating a volume change of a sample under tension, with a sample being scanned by a first light beam and the light beam reflected from the sample being detected and further processed. The sample is then illuminated with at least one additional light beam of finite width, with the light beam being converted into a first voltage behind the sample, and a transverse pattern of different reflectivity is scanned by the first light beam longitudinally, and with the change in frequency, produced by stretching, in the reflected light intensity-modulated in this fashion being converted into a corresponding second voltage and the voltages are compared with one another, possibly after calibration.

Abstract: A method is disclosed for measuring the rate and/or extent of movement of oscillatory element positioned on an oscillating system by passing a reference beam towards a reference detector over a reference edge. The reference edge is fixed relative to the element. The measurement beam is directed towards the measurement detector over a measurement edge of a surface adapted to move together with the element relative to the reference edge. The movement of the measurement edge cuts the measurement beam as it moves into the path of the measurement beam. The rate and/or extent of movement of the element relative to the reference edge is determined by comparing the illumination received by each of the detectors. Apparatus is also disclosed for measuring the rate and/or extent of movement of an oscillatory element positioned on an oscillating system including a measurement edge adapted to move together with the element. A reference edge is maintained stationary relative to the measurement edge.

Abstract: A parallel pencil of light, for example, a laser beam, is expanded by means of a cylindrical lens. The lens is fully cylindrical and has an optically thinner medium of cylindrical shape in its interior. The lens is arranged relative to the pencil of light so that total reflection occurs at the interface with the optically thinner medium.
