Patent DE-4217821-A1 (DE)
Title: Multistage optical coupling network with frequency-dependent stage - is based on switch matrix which forwards multifrequency signal combinations for demultiplexing to several more receivers
Inventor: WEBER JENS DIPL ING DR
IPC: H04B10/272
Filed: 1992-05-29
Abstract: The number of inputs to the network (10) is a multiple (n) of the number of frequencies (k) to which the transmitters (21-2kn) can be tuned. A control circuit (32) demodulates the input signals and operates a broadband switch matrix (31) accordingly. Conventional measures are applied for extracting the frequency (fo) of the optical routing instruction signal and preventing crosstalk among the inputs. The switch matrix supplies n outputs without selection of frequencies (f1-fk) to separate de-multiplexers (51-5n) which serve an equal number of receivers (41-4kn). USE/ADVANTAGE - For communication between gps. of optical transmitters and receivers. Large numbers of subscriber connections can be served without division of optical spectrum into too many individual bands.

Title: Method for forming external toothing on hollow shafts - axial pressure forces are applied to material under section to be formed and produce multi-axial stress condition in workpiece
Inventor: EICHNER KLAUS WERNER PROF DR I
IPC: B21K21/00
Filed: 1992-07-31
Abstract: During the gear cutting, dies (3a,b) apply defined axial pressure forces (FSt) on either side, below the workpiece area to be toothed. This produces a defined multi-axial stress condition in the workpiece (1), and the radial stresses thus generated favour the material flow for profile forming. The workpieces have a solid section (2), where the toothing is to be formed. Two dies with opposite end faces engage into the hollow of the shaft. The dies apply the axial pressure forces to the solid section, to generate the defined stress condition. USE/ADVANTAGE  - Light-weight hollow shafts. Guarantees good profile forming even with high-tensile materials.

Title: Carpet yarn prodn
Inventor: STEINER ERWIN
IPC: D02G1/12
Filed: 1992-12-23
Abstract: A carpet yarn texturising installation has a stuffer box, with continuous extraction equipment. The entrance to the box is through vertical feed rollers and the exit has a trap leading to a channel which widens out at the sides.A creel holds reels of yarn which is fed into the texturiser. This has various sections (3), held on a stand. The yarn is drawn through between vertical input rollers, and is pushed into a stuffer box compartment, which is square in section. Random loops are held against the spring held trap at the outlet of the box, so that the yarn is crimped. An accumulation of yarn is gradually released into a larger section channel, and as the yarn progresses the sides of the channel are angled outwards, while the top and bottom remain parallel. The yarn spreads out of the width or part of the width of the conveyor band (9). The conveyor passes through the steam heating cabinet where the yarn has superheated steam application to set the crimp. Thereafter it is deflected into an accumulator and wound at position on to reels.
