Abstract: The gearing and clutch unit for a two-wheeled motor vehicle comprises a housing (11) in which an input shaft (13), an output shaft (27) and a countershaft (43) are mounted in such a way that they can rotate relative to one another. Connected to the input shaft (13) is a starting clutch (19) designed, in particular, as a centrifugal clutch, which, in turn, is connected to the output shaft (27) via two gearing transmission paths with different transmission ratios. The first gearing transmission path leads to the output shaft (27) via the countershaft (43) and an overrunning clutch (47). The second gearing transmission path contains a gear-change clutch (61) designed as a friction clutch and having two clutch members (67, 71) arranged coaxially on the output shaft (27). The first (71) of these clutch members, which can be displaced manually by means of an actuating device, is spring-loaded into its disengaged position. The first clutch member (71) is connected to the output shaft (27) via a coarse-pitch thread (69) and is screwed towards the second clutch member (67) by the friction torque transmitted in the engaged position. The gear-change clutch (61) can thus only be disengaged when the internal combustion engine (1) is relieved of torque, an unwanted increase in the speed of the internal combustion engine when changing down from second to first gear thereby being avoided.

Inventor: JOCHAM BERTHOLD
IPC: G01N19/08
Filed: 1989-10-03
Abstract: This mechanical device picks up round rings without difficulty and rotates them around a centre point whose position is always the same. Two shaped jaws travelling in opposite directions produce deformation from the circular shape and as a result tensile stresses arise in the surface of the round ring depending on its rotational position. This reveals the smallest surface flaws in the form of, for example, cracks. The gate aperture of a CCD camera always records a particular area of the ring cross section in the region of increased surface tension. The mechanically reliable deformation with the position and shape of the round ring always being the same makes automation of the testing operation by means of digital image processing possible for the first time, such processing being required in connection with the use of round rings in safety systems (for example in cars). <IMAGE>

Abstract: A region from two frames of a television picture is subjected to Fourier transform in processing stages (3 and 4) one via a picture memory (2), and the resulting transforms compared in a comparator (5) whose output is subjected to inverse Fourier transform in a processing stage (6). The output of comparator (5) is also applied to a sample rate modifier (7) in which this output is enlarged prior to being subjected to inverse Fourier transform in a further processing stage (8). The outputs of processing stages (6 and 8) are respectively low and higher correlation functions of one pixel and one-quarter pixel resolution respectively. A given number, say 20, of sample points of greatest magnitude in the low resolution correlation function are selected in a largest vector selector (9) whose coordinates are used in a peak locator (10) which locates the peaks in the higher resolution correlation function associated with the selected samples to produce coordinates for these peaks to quarter pixel accuracy. A limited number of these, say 10, can be selected by a vector limiter (11) if used with a system having limited data capacity for motion vectors.
