Inventor: MAINBERGER THOMAS
IPC: B21C37/08
Filed: 2003-12-16
Abstract: The pipe section is formed from a steel sheet billet. This is punched out forming two straight side edges, a slightly curved rear edge, and a stronger curved front edge. The blank is curved until the side edges engage and are connected by Laser welding etc. to form a tube (10). The tube is placed into a mould (20), a straight first mandrel (23) and a second curved internal mandrel (24) are introduced into the tube, and a tubular press die (25) enclosing the straight mandrel is moved into place. The tube is pressed into the gap between the mandrels and the mould, forming the curved tube section and flat edged intake and outlet apertures. The tube is esp. for use as end pipe and exhaust systems in motor vehicles with Diesel engines.

Title: Procedure for determining object geometry via multi=position 3d=sensor
Inventor: BREUCKMANN BERNHARD DR
IPC: G01B11/00
Filed: 1996-07-04
Abstract: A procedure for determining the location, shape, accuracy of form etc. of objects subject to change employs 3-dimensional optical measurement incorporating a projector for illuminating the object such as to produce a specific optical pattern(2) over its surface(3). A 3d-sensor(4) observes a field of measurement(5) from a position(6) to identify by co-ordinates the then existing orientation of the sensor(4) w.r.t. at least three of the pattern marks(7). The procedure is repeated for additional overlapping fields (9, etc) observed from other sensor positions(8,11) and the collective position data is composter evaluated using established rules of multi-coordinate transformation to define object geometry w.r.t. common axes of reference.
Patent DE-19627216-A1 (DE)
Inventor: TILLEROT FRANCOIS
IPC: H04J14/02
Filed: 1996-07-05
Abstract: A device for the frequency transposition of optical signals, receiving data elements at a variety of different wavelengths (* small Greek lambda *0 , * small Greek lambda *1 ... * small Greek lambda *n ) and outputting these data elements at a single wavelength (* small Greek lambda *0 ), which equals one of the original reception wavelengths. The device comprises a circulator 30 that receives the input signals (* small Greek lambda *0 , * small Greek lambda *1 ... * small Greek lambda *n ) at a port 1 and transmits them via port 2 to an arm comprising a rejection filter 31, that reflects * small Greek lambda *0 signals back into port 2, followed by a wavelength converter 32 that converts all the other signals (* small Greek lambda *1 , * small Greek lambda *2 ... * small Greek lambda *n ) into signals at * small Greek lambda *0 . The circulator 30 also transmits the reflected * small Greek lambda *0 signal out of port 3 into an optical delay 33. A passive optical coupler 34 connects the outputs of the two arms, outputting a complete set of signals, all at * small Greek lambda *0 . This avoids feeding the * small Greek lambda *0 signal through the * small Greek lambda *0 converter, which would significantly decrease the quality of that signal. Other embodiments of the invention can comprise more than one conversion arm. The invention can be applied to asynchronous packet or synchronous frame transmission packet systems.
