Patent DE-19734716-A1 (DE)
Inventor: MESETH JOHANN DR
IPC: B04C3/04
Filed: 1997-08-11
Abstract: The invention relates to a separator (1) for a steam-water mixture. The inventive separator is located in the reactor pressure vessel (60) of a boiling water reactor plant on the core lid (11), and is characterised by its simple structure. The separator (1) has an inlet (8) through which the mixture flows into said separator (1) with a radial flow component. A rotational flow is created by means of a twist structure (40) located in the inlet (8). As a result of the rotational flow, the mixture is separated into steam (v) and water (w) in a separation chamber (10) located downstream from the inlet (8). The water (w) leaves the separator (1) via an annular off-flow opening (17) located on the outer periphery (52) of the separation chamber (10). The steam (v) is led out of the separator (1) via an off-flow pipe (16), above the height of the filling level (44) of the coolant in the reactor pressure vessel (60). The inventive separator (1) separates the steam and water so effectively that e.g., downstream steam dryers are not required.

Patent DE-19820324-A1 (DE)
Inventor: SEJA WERNER
IPC: H04L1/22
Filed: 1998-05-07
Abstract: The invention relates to a method and device for monitoring data flow, specially to provide radar data for air traffic control systems. In order to detect data supply failures and to provide an automatic replacement supply, the data which is transmitted is computed at the output of the data transmission device at parameterable time intervals, whereupon the data flow is reproduced, the measuring values are stored during several intervals and compressed into an average value. When a new value is inputted, the oldest value is erased. The average value is used as a starting value for a sensitivity curve which generates a time window for periodic comparison of added measuring values for an error detector which signalizes a total failure of measuring values in a predetermined time unit and initiates a selection mode to access a predefined data source in an appropriate data network and the data is inputted into the respective data supply system via interfaces.
