Title: Machine tool spindle with built-in actuation of chuck - has sleeve in bore which can be unlocked from spindle to allow nut driving drawbar to be rotated
Inventor: BURGTORF HEINRICH
IPC: B23B31/30
Filed: 1991-01-14
Abstract: The use of a motor directly coupled to the machine spindle precludes the actuation of the chuck drawbar by an external mechanism. In the invention the drawbar (5), which rotates with the chuck and spindle (2, 4) passes through a drawbar actuating sleeve (7, 11, 16), and is screwed into a keyed sliding nut (12, 13) against the pressure of spring (14). With the chuck clamped (as shown) the actuating sleeve is locked to the spindle by balls (8) which are forced intot he pockets (18) of the sleeve by the sliding collar (9) keyed to the spindle. The spindle is driven by the motor (10) directly coupled to the sleeve. To release the chuck the spindle is first halted at the correct rotational position. The collar (9) is then moved to the right, uncoupling the spindle and sleeve and locking the spindle to the housing. The sleeve and nut ae rotated by the motor (10) to move the drawbar to the left and release the chuck closing the chuck is down by a reverse process. USE/ADVANTAGE - Particularly for clamping tools and workpieces in multi-spindle machines without access for an external acutation of chuck drawbar.

Title: Valve for treating hydrocephalus patient - has capsule which is sensitive to small changes of pressure
Inventor: AFFELD KLAUS PROF DR ING
IPC: A61M27/00
Filed: 1991-09-11
Abstract: A uniform pressure is maintained inside the skull of a hydrocephalous patient by a valve. The valve consists of a flexible tube with an inlet (1). The flow through the tube can be shut off by compressing the tube by a projection from a pressure plate (4). The pressure plate is forced against the tube by springs (6). A capsule (3) is mounted in contact with the pressure plate on the side opposite to the springs. The capsule (3) is connected to the flexible tube upstream of the closure point (5). As the pressure in the capsule rises it overcomes the force of the springs and lifts the pressure plate away from the tube to allow flow throughout. USE/ADVANTAGE - Treatment of hydrocephalous patient by a device which is sensitive to small pressure changes.

Title: Signal-processing method for logic analyser and circuit and device for carrying out the method
Inventor: KOLLER ROMAN
IPC: G06F11/25
Filed: 1992-05-25
Abstract: The invention relates to a method for application in logic analysers, in which for the first time the following real-time execution is possible: a signal pattern of a logic circuit, in particular high-speed logic circuits, is scanned using direct evaluation of all the times which form the respective logic circuit directly with respect to the ICs (circuits), according to an acceptable tolerance range in accordance with data sheet specification including bidirectional bus connection (tristate) in uninterrupted measurement, with the particular variant that this takes place independently of the operating clock of the circuit so that the operating clock (processor clock) can also be swept in order to search the circuit during the test for worst case (worst operating state) automatically by means of its specific resonance behaviour. Furthermore, a vacuum adaptor is preferred for the method, which vacuum adaptor differs from the prior art in that it is designed as a mini tap base which can be fitted directly onto the printed circuit board, as a result of which maximum universality, in particular for steep signal edges, is ensured. Furthermore there is provision for a mini adaptor base to be optionally equipped with diverse adaptor electronic circuit boards using mini plug-in unit technology. A further special feature is a miniature high-power vacuum pump which can be of very cheap design, operates noiselessly as a result of simple damping means and therefore ... even directly in devices such as oscilloscopes, logic analysers ...
