Patent DE-19543044-A1 (DE)
Inventor: HERMES THOMAS DR ING
IPC: H04J14/02
Filed: 1995-11-06
Abstract: Optical frequency multiplexing systems with heterodyne receivers have channel occupation patterns in which the positions of adjacent channels are predetermined. When the frequency spacing between adjacent channels is constant (d = IF + fb, cf. figure 5), the limited available bandwidth is not optimally used. In order to reduce channel spacing, and so increase the number of channels up to their double, alternatively different channel spacings d1 and d2 are defined between every two adjacent channels (cf. figures 1 to 4). The marginal conditions that need to be met are in any case met to such an extent that no unacceptable degradation of the transmission quality is caused.

Title: Belt tightener with tensioning spring for safety belt for vehicle
Inventor: TEDER LEONID
IPC: B60R22/195
Filed: 1996-07-19
Abstract: The belt tightener includes a sensor spring (36) seated between the base of axial drilling (34) and the screw head (32). A blocking element at the other end of sensor mass (35) has a head (38), with two flat parallel blocking surfaces. The element is held between two rollers (39,40). Their parallel axes lie at right angles to the longitudinal axis. The first roller is supported at abutment (42). The second roller supports itself at a plane rolling surface (43) lying parallel to the blocking surfaces.  At the end of the contact arm of the end lever of the lever system, which introduces the reduced force of the tensioning spring (8) across the second roller, are the head of the blocking element and the first roller in the abutment. So that the axial forward movements of the sensor mass have blocking element, resulting from the vehicle deceleration against the effect of the sensor spring, with the exceeding of a specified deceleration, a rolling or a stalling of at least the second roller from the blocking element leads to an activation of the lever system and the release of the tensioning spring.
