Patent DE-19530261-A1 (DE)
Title: Low-pressure fuel injection system for vehicle IC engine
Inventor: PAPE ERWIN DIPL ING
IPC: F02M69/54
Filed: 1995-08-17
Abstract: The fuel injection system has a fuel pump (3) operating at relatively low pressure and a control valve (4) which returns excess fuel to the fuel tank (2). When the engine is switched off the fuel pump is operated for a sufficient time to build up the fuel pressure to a second, higher level, with the return flow (7) blocked. This ensures that vapour lock is prevented at the injector and allows a hot re-start. The excess pressure remains until the injectors have cooled sufficiently to prevent vapour lock. A processor control (8) monitors the full pressure (5) and the temperatures of the injectors (12) and of the exhaust (11).

Patent DE-19545280-A1 (DE)
Title: Demodulating simultaneously amplitude and phase modulated functions for technical diagnosis
Inventor: BITTNER HELMAR DR ING
IPC: H03D5/00
Filed: 1995-12-05
Abstract: The method involves first subjecting the signal, to be demodulated, to the Hilbert transform process, thus generating a second signal. Both of the signals are squared and added, thus generating an amplitude demodulation resultant signal. The method now involves a quotient process, in which the phase modulated signal is differentiated and Hilbert transformed, generating two new signals, mutually related, to determine the phase modulated signal.  First the amplitude demodulation is carried out.  Then the quotient of the squared signal and the amplitude demodulation result is formed for separating the amplitude and phase demodulated signal portions.  Then the phase demodulation result is determined.

Patent DE-19641522-A1 (DE)
Inventor: VOBIAN JOACHIM DR
IPC: H01S3/098
Filed: 1996-09-30
Abstract: The invention concerns a method of manipulating a compensation fibre such that it can compensate the high negative dispersion of a fibre laser in the second optical window. According to the invention, the active fibre of the fibre laser is linked to a compensation fibre which consists of a step-index quartz glass core with a sheathing. By doping the compensation fibre sheathing with fluorine in a targeted manner, a positive value is set for the dispersion of the compensation fibre. Subsequent dimensioning of the length of the compensation fibre increases the set dispersion value to the positive dispersion value necessary for complete compensation of the dispersion of the fibre laser.
