Abstract: The invention concerns a set of surgical instruments for operating on cartilage, bone or body tissue areas, said set of surgical instruments comprising a surgical instrument (1) and a device (2) for guiding this instrument and/or a tissue applicator (3) for introducing tissue at a defect to be covered. According to the invention, the surgical instrument which can be guided in a circular or elliptical manner, or even in other manners, by means of the claimed guide device (2) takes the form of a shaver, scalpel, drill, curette, syringe or also a probe. Depending on the surgical context, however, other instruments for cutting, milling, stamping, sewing or drilling bores in cartilage, bone or body tissue or injecting operative auxiliary substances such as, for example, adhesive, can be guided by the claimed guide device in a specific areal shape.
Patent DE-19708792-A1 (DE)
Inventor: LUGER SIEGFRIED
IPC: H05B41/298
Filed: 1997-03-04
Abstract: The invention relates to a method for detecting the rectification effect in at least one gas discharge lamp (10) and to an electronic ballast operating at least one gas discharge lamp (10) detecting the occurrence of said effect therein. The current (i1) flowing through a primary winding (7A) of a heat transformer (7A-C) which is parallel connected to the gas discharge lamp (10) or a variable (i2, u3) dependent upon said current (i1) is monitored in order to provide high-sensitivity detection of the rectification effect occurring in the gas discharge lamp (10). Cut-off results when a predetermined limit is exceeded upon occurrence of the rectification effect in said gas discharge lamp (10).
Patent DE-19713276-A1 (DE)
Inventor: KEHR ULRICH
IPC: G02B7/04
Filed: 1997-03-29
Abstract: The invention relates to a device (10) for positioning components (42) in an endoscopic system, with a hermetically sealed housing (12). An exterior ring element runs around the exterior of the housing (12), said ring element being arranged so that it can rotate. This exterior ring element supports at least one magnet (18) peripherally. An interior ring element is also arranged in the sealed housing (12). The interior ring element also supports a magnet (34), and the magnets (18, 34) are arranged in such a way that when the exterior ring element is turned, the at least one interior magnet is also moved by means of magnetic attraction. This movement is used for positioning the component (42). In order to ensure a simple, compact assembly which functions reliably, the invention suggests that both the exterior and interior ring elements are configured as rings (14, 30) which are arranged so that they can rotate but cannot be displaced axially, that the rings support the magnets (18, 34) in such a way that they oppose each other, and that the interior ring is connected mechanically to the component which requires positioning (42).

Abstract: The invention relates to a clutch (1), comprising a sliding sleeve (17) with selector teeth (19) and two synchronising rings (28, 29) situated either side of the sliding sleeve (17). Said synchronising rings (28, 29) have locking teeth (30, 31) and a friction surface (24, 25), and can be turned about a limited rotation angle in relation to the sliding sleeve (17). The inventive clutch also comprises two clutch bodies (20, 21) with clutch teeth (22, 23) and a counter friction surface (26, 27), said clutch bodies (20, 21) interacting with the synchronising rings (28, 29).

Patent DE-19743168-A1 (DE)
Inventor: BRAKEMEIER ACHIM
IPC: H04L25/03
Filed: 1997-09-30
Abstract: The invention relates to a method for equalising a signal received via a time variable transmission channel by means of an equalisation filter with decision feedback. According to said method, a channel mismatched filter is provided as a first transversal filter in the continuous signal path. The filter coefficients of said channel mismatched filter are selected in such a way that the cross-correlation function of the channel step response and the step response of the channel mismatched filter has no or negligible overshoot. Consequently, the correction of overshoot distortions is essentially more simple or is completely unnecessary. The filter coefficients are easier to determine and the equalisation is more robust as a result of the transversal filtering being less complex.

Title: Pneumatic brake force intensifier for motor vehicles
Inventor: FEIGEL HANS-JOERG DR
IPC: B60T13/57
Filed: 1997-10-04
Abstract: The device has a two-part valve piston (6), with a first part (31) acting with an actuator rod (7), and a second part (32), e.g. a sleeve, which slides through the first part and carries a second sealing seat (16). Elements (34,35,36) to give discontinuous increase in the intensifier force form a power-transmitting connection of the second valve part with the control housing (8,14) when the second sealing seat is at a set distance (a) to the valve body (10,23). Movement of the valve piston against the actuating direction of the control valve (5) switches off the effect of the elements.
