Abstract: The surface finishing system for rotationally symmetrical workpieces has a number of successive machining stations along the workpiece feed path, using individually adjustable finishing stores (20) vibrated via a common oscillation drive (32). The latter is monitored by an oscillation sensor (50) providing an electrical output signal for a control microprocessor (80). This compares the detected oscillation with a supplied reference value to allow a constant oscillation amplitude to be maintained. The oscillation is detected via an acceleration sensor coupled to the microprocessor (80) via integrators.

IPC: H02N2/00
Filed: 1989-02-08
Abstract: An optical fibre (12) is connected to a structure (10) so as to be deformed by the latter's movement. Light is directed into the optical fibre (12) and a detector (16) detects changes in the light signal indicating movement of the fibre (12) caused by movement or deformation of the structure (10). The detector output is processed (17) so as to operate one or more piezo-electric actuators (34,36) attached to the structure (10). The piezo-electric actuators (34,36) may therefore dampen the movement of the structure (10) or may be used to re-position the structure (10). The structure (10) may be an aerofoil for example.

Abstract: The invention relates to a method for enlarging metal, especially steel, hollow profiles essentially open at the end faces to a shape which is predetermined by a divided outer die surrounding the hollow profile, the end faces being sealed by means of sealing heads and a hydraulic internal pressure being applied inside the hollow profile for the purpose of deformation. In order to specify a method for hydraulically enlarging metal hollow profiles which can be carried out as simply as possible and in which, in particular, the hollow profile is sealed off without great outlay in terms of equipment, it is proposed that the rigid part of the sealing heads should in each case be sealed off from the hollow profile via a flexible hollow sealing ring by subjecting the interior of the sealing ring to a pressure P1 which is at all times greater than the particular pressure P2 used for deforming the hollow profile, and bringing it to rest against the inner or outer surface of the hollow profile, the enlargement of the hollow profile in the region of the sealing ring being limited from the outside to within the capability of the sealing ring to adapt to the surface of the hollow profile.

Abstract: When confidential information items are processed on display devices, it is required that these confidential information items be made invisible for a short time on the display device if persons unauthorised for these information items come to the work station. According to the invention, this is achieved by the fact that the display on the display device is blanked out by an input device and reinserted by control pulses given to a control unit. For this purpose, the keyboard can have a blanking key by the first actuation of which the display can be blanked out and by a second actuation of which it can be reinserted. The person processing the confidential information on the display device can thus render the display on the display device invisible for a short time on the display device by simply actuating the blanking key. <IMAGE>

Abstract: Apparatus and method for collision detection in a multi-robot system. A "map" of the "world" is stored in memory. A collision map containing a desired robot move is created. The initial position of the desired robot is removed from the "world" map by combining the robot map and the "world" map in a logical exclusive-OR operation and thereafter combining the collision map and the "world" map in a logical exclusive-OR operation followed by combining the collision map and the "world" map in a logical "inclusive-OR" operation in a byte-by-byte manner. A collision is indicated by a difference in any bit position of the inclusive and exclusive-OR combinations. The lack of any difference indicates that the move may be made. Similar logic operations are performed to partially and ultimately totally deallocate an allocated path and for considering alternative moves or partial moves responsive to the presence of a "collision". The method is performed using a computer which may be no more sophisticated than a conventional personal computer (i.e. PC) in which calculations are capable of being performed within a millisecond, which operating speed favorably compares with the movement of a robot which requires of the order of one second.
