Patent DE-3919497-A1 (DE)
Inventor: LEFELDT EKKEHARD
IPC: G01R31/11
Filed: 1989-06-15
Abstract: In this method it is provided to write the recording of a fault pattern and a healthy pattern one above the other via a digital memory and to use pulses which have the same amplitude and curve shape. For this purpose, an arc is generated at the fault location and when the capacitor is discharged through the arc current to a voltage below the ignition voltage of the fault location, the existing residual charge of the capacitor is fed to the cable in the manner of a pulse and the reflected wave is detected via a channel of the digital memory. Subsequently, after disconnecting the cable and recharging the capacitor to a voltage below the ignition voltage of the fault location, a new discharge will occur via the cable, the reflected wave produced being recorded via a second channel of the digital memory. When the two recordings are written one above the other, the point of deviation is used for determining the fault location. <IMAGE>

Patent DE-3941327-A1 (DE)
Inventor: FRICKE HELLMUTH
IPC: H05B39/10
Filed: 1989-12-14
Abstract: The circuit is designed such that it assumes a first switching state when a monitored signalling lamp (L) is operating correctly, and a second switching state in the event of a fault. A fault is regarded as the interruption of the supply circuit passing through the main filament (HF) when the signalling lamp is switched on and, when the main filament is intact, lack of readiness of the standby filament (NF) of this signalling lamp to switch on. An alarm (M), which is connected in series with the standby filament of the signalling lamp in a high-resistance manner, is used to emit a monitoring alarm. This alarm is short-circuited by the switching means (JH/1) of an indicator (JH) connected in series with the main filament, when the main filament circuit is broken, and is also deactivated when the standby filament circuit is broken. The circuit is particularly suitable for functional monitoring of signalling lamps in railway signalling lights. <IMAGE>

Patent DE-4101910-A1 (DE)
Inventor: NITSCH ERNST
IPC: A61K31/733
Filed: 1991-01-23
Abstract: Described is a method of preparing a fructane which is readily soluble in water and a physiologically compatible kidney-examination agent containing such a fructane. The method calls for an aqueous fructane extract obtained from plant matter to be ultra-filtered through a first membrane which retains high-molecular-weight carbohydrates and proteins but allows the fructane to pass through. The filtrate thus obtained is then subjected to a second ultra-filtration operation using a membrane which retains the fructane but allows salts and other low-molecular compounds such as mono- and oligosaccharides to pass through. The fructane obtained in this way is used, together with physiologically compatible buffer compounds, as a kidney-examination agent at an osmolality equal to that of blood and at a pH of 5.0 to 7.0.
