Title: Folding and guiding device for an endless conveyor band composed of segments
Inventor: BRANDAUER EDGAR DR ING
IPC: B65G17/18
Filed: 1993-06-04
Abstract: The invention relates to a folding and guiding device for an endless conveyor band which is composed of segments and which is guided between at least two deflecting devices. The object was to develop a folding and guiding device which makes do with substantially fewer operating elements than known solutions and which is characterised by robustness and operating reliability and is therefore suitable for providing a device of high efficiency. With this in view, sliding or rolling devices are used on the pull means and the folding segments. For the guidance of the conveyor band, these sliding or rolling devices engage into guide tracks arranged parallel to the band. The design of the guide tracks makes it possible to fold open the segments in predetermined regions. Closing takes place in various ways on the deflecting devices. <IMAGE>

Title: Interferometric determination esp. of rotational movements of object being measured
Inventor: LEWIN ANDREW DR
IPC: G01P3/36
Filed: 1994-07-15
Abstract: The interferometric determination involves a pair of measuring beams (3,4) emanating from a laser (7) which are reflected back from an object (1) being measured as signal beams (5,6). Each measuring beam (3,4) runs through a separate heterodyne-interferometer (12,13), in which a component is branched off as a reference beam (16,17). The signal beams (5,6) reflected back from the object (1) being measured in the interferometer are respectively superimposed on the reference beams, and the speed information of the measurement object (1) is obtained from the resulting output signals of both interferometers at detectors (23,24). In addition, the complementary interferometer outputs at detectors (25,26) are differentially combined to optimise the signal sent to an electronic evaluation unit.

Title: Bolt lock
IPC: E05B13/00
Filed: 1994-10-10
Abstract: The invention relates to a bolt lock (1) for a platform gate (drop side, sideboard) of a commercial vehicle or the like, with a locking bolt (3) for interaction with a counterholder (15), which locking bolt (3) can be moved by means of a locking lever (4) between an open position and a locking position, the locking bolt (3) being arranged in a preferably trough-like housing (2).

Title: Apparatus and method for measuring the refraction
Inventor: KRUEGER HELMUT
IPC: A61B3/10
Filed: 1983-02-10
Abstract: Ophtalmologic method useful for measuring the eye refringency with an enhanced time resolution. In order to proceed to the measurement, the image of an object is reproduced on the retina. The sharpness of said object image is controlled according to the light reflected by the retina, as a function of the distance between the eye and the object. The measurements are effected with narrow band invisible infrared light, which does not upset the sight and reduces the influence of the chromatic aberration of the eye. With said method, what is aimed at is not the distance between the eye and the object, at which distance the image of said object on the retina is sharper, but two distances at which the image is equally unsharp or fuzzy. By using said method, a differential signal is obtained with a very good signal/noise ratio allowing to determine the refringency of the eye. The apparatus and method are particularly appropriate for the automatic and objective measurement of the reflection, particularly the accomodation, timewise, of the human eye in relation to distances when the latter are modified, in other words they may be used not only to measure the static functions but also the dynamic functions.
