Patent DE-19848721-A1 (DE)
Inventor: MENZEL WOLFGANG PROF DR
IPC: H01Q1/38
Filed: 1998-10-22
Abstract: The invention relates to a device for changing the polarization of an incident electromagnetic wave. Existing devices to change the polarization of an incident electromagnetic wave preserve signal decoupling, i.e. the relation between useful polarization and cross-polarization of the incoming signal. Furthermore, said devices are far too big for many applications. The aim of the inventive device is to improve signal decoupling. During transmission of an electromagnetic wave through the transmission polarizer, the cross-coupled fraction of an incoming signal is greatly reflected thus leading to improved decoupling of the transmitted signal. Furthermore, the transmission polarizer can be manufactured in the form of a single planar printed board. The transmission polarizer is particularly useful to change the polarization of an incident electromagnetic wave, i.e. from linear to circular polarization or vice versa, and to rotate the polarization of an incident electromagnetic wave around a fixed angle.

Title: Anordnung zur Erkennung von Schienenbrüchen und Eisenbahnschiene
Inventor: MINDEL KLAUS
IPC: B61L23/04
Filed: 1998-11-11
Abstract: Es wird eine Anordndung zur Erkennung von Schienenbrüchen angegeben, die eine Schiene (SCH), eine an der Schiene befestigte optische Faser (OF) und eine Auswerteeinrichtung zum Erfassen von durch die optische Faser übertragenen Signalen umfaßt. Erfindungsgemäß ist die optische Faser im Bereich des Schienenkopfes (KOPF) befestigt. Auf diese Weise wird die optische Faser nicht nur unterbrochen, wenn die Schiene vollständig durchbricht, sondern auch dann, wenn lediglich der Schienenkopf einreißt oder teilweise herausbricht. Ein unerkanntes Durchtrennen der Schiene im Rahmen eines Sabotageakts ist nicht möglich, da dabei immer auch die optische Faser durchtrennt werden muß. Da die Auswerteeinrichtung lediglich zu überwachen braucht, ob ein in die Faser eingekoppelter Lichtstrahl unterbrochen ist oder nicht, ist keine aufwendige Signalregenerierung und -auswertung notwendig. Entsprechend weit können Lichtsender und Auswerteeinrichtung voneinander entfernt sein.

Inventor: KROISS HUGO
IPC: F02M37/38
Filed: 1999-03-12
Abstract: A fuel supply system (1) for a motor vehicle is known in which the fuel flows through the fuel filter (6) of the fuel supply system in one direction only. In such a system, any sediments (10) that are present in the fuel are deposited on the filter material (8) so that the flow resistance of the filter material is gradually increasing. The aim of the invention is to provide a fuel supply system for a motor vehicle in which the flow resistance of the fuel filter remains virtually constant. To this end, a sedimentation pan (9) is provided in a housing of the fuel filter (6) below the filter material (8) which is mounted in the housing (7) in which pan the sediments (10) filtered off from the fuel (4) are deposited. An accumulator (15) is mounted in the fuel supply system that allows that the fuel (4) stored in the accumulator (15) scavenges the fuel filter (6) once the engine is switched off.
