Abstract: An impedance arrangement (10) is provided for use in a high-voltage circuit. For example, the impedance arrangement (10) is useful in a circuit which includes reactance elements (e.g., 52) and a high-voltage circuit-switching device (e.g., 50). The impedance arrangement (10) limits transient inrush current and/or voltages in a first frequency range (e.g., 200-750 hz) which occur in the circuit during closure of the circuit-switching device and damps transients in a second frequency range (e.g., 10-200 khz) which occur in the circuit during opening of the circuit-switching device (50). The impedance arrangement (10) is also useful in applications requiring tuning reactors and current-limiting reactors to limit abnormal power-frequency currents, harmonics, transients, and/or high-frequency inrush currents. The impedance arrangement (10) functions predominantly as an inductive impedance over the first frequency range (200-750 hz); e.g., corresponding to the frequencies of transients encountered during the closing of the circuit-switching device. Additionally, the impedance arrangement (10) functions predominantly as a resistance over the second frequency range (10-200 khz) which is higher than the first frequency range (200-750 hz); e.g., corresponding to the frequencies of transient conditions on a power system such as are encountered during the opening of the circuit-switching device. The impedance arrangement comprises a first winding (12) having a first predetermined inductance (L1) and a second winding (14) connected in parallel with the first winding (12). The second winding (14) has a second predetermined inductance (L2) and a second predetermined resistance (R2). The second winding (14) is wound with respect to the first winding in an opposite sense to the first winding (12) and so to define a predetermined mutual inductance (Lm) between the first (L1) and second (L2) inductances.

Abstract: The invention relates to a diagonal flow filter module, particularly for ultra- and microfiltration. The diagonal flow filter module consists of a cuboid stack element (5) with alternating flow channels (9) for crude solution or retentate and filtrate channels (10), which are separated from one another in each case by a filter membrane (6). The flow channels (9) are closed off at the side walls of the stack element (5), while the filtrate channels (10) have openings at the side walls for the discharge of the filtrate. The flow channels (9) are open at the end faces of the stack element (5) and the filtrate channels (10) are closed. The ends of the stack element (5) are sealed to a housing (1) with a synthetic resin composition. Sealed to the end faces there are end caps (12) with the connections for crude solutions and retentate which, together with the seal between the stack ends and the housing (1), ensures a reliable separation between retentate and filtrate space. The filtrate leaves the stack element (5) at the side walls, is collected in the housing (1) and withdrawn through one or two drainage connecting pieces. The diagonal flow filter module has an improved flow guidance system and permits a larger connection cross section to be realized.

Abstract: In such a position measuring device for measuring the relative position of two objects, the graduation (T) of a scale (TT), connected to one of the objects, is scanned by a scanning device (A) connected to the other object. The scanning device (A) exhibits an illumination unit (B) to generate two periodic scanning signals (S1, S2), which are passed in the one case to an evaluation device (W) to form measurement values for the relative position of the two objects and in the other case to an error warning device (F) to generate an error signal (FS) in the case of erroneous signal parameters of the periodic scanning signals (S1, S2). In order to check the amplitude magnitudes of the two periodic scanning signals (S1, S2), the normal supply voltage (V) for the scanning device (A) is dropped to a reduced supply voltage (Va) for a specified test time (T), so that the brightness level of the illumination unit (B) is reduced and thereby the amplitude magnitudes of the two periodic scanning signals (S1, S2) are reduced. If the error warning device (F) emits an error signal (FS) during this test time (T), then this is considered to be an advance warning that the brightness of the illumination unit (B) will soon no longer be adequate for a perfect measurement. <IMAGE>

Abstract: Methods of preparing storage stable components useful for metathesis bulk polymerization of cycloolefin monomers are provided. These components contain cycloolefins with norbornene-functional groups and cocatalysts activated with a halometal compound. In these methods, the cocatalyst is completely formed before the halometal activator is added to prevent the formation of unwanted hydrogen halides, which catalyze undesired crosslinking reactions which destabilize the cocatalyst component. Bulk polymerization systems are provided wherein these storage stable cocatalyst components are paired with catalyst components that together form the complete metathesis catalyst system. For some embodiments, storage stability is aided by the removal of water.

Title: Method and device for the generation of pulse sequences for a number of signal lines
IPC: H04M19/02
Filed: 1989-08-03
Granted: 1993-07-21
Abstract: The method uses a binary coded counting device (BZ), which can be advanced by the clock pulses (MT0) of a pulse transmitter (IG). The signal combination (ZS) occurring in each case at the control outputs (ZOUT) of the counting device (BZ) forms, together with additional condition signals (CMD, CS) a total combination (GK) which is used for the further evaluation. In addition, clock pulses (MT0, MT1) can act on the connected signal lines (SIG) for forming the desired pulse sequences. Counts can be skipped or the advancing of the counting device (BZ) can be interrupted in that, when a total combination (GK) is present, a count (ZSL) determining the starting point for the further counting sequence is generated and, in conjunction with a corresponding loading signal (LD), loaded into the counting device (BZ). <IMAGE>
