Patent DE-59009252-D1 (DE)
Inventor: KUFNER HERWIG DIPL ING
IPC: H02M1/12

Abstract: The operation of power converters places shift and distortion reactive power on the main power system. The interference currents thus generated can be short-circuited by impedance circuits, but this measure is not always sufficient. It is therefore proposed according to the invention to connect a controlled feedback auxiliary converter (2) using fast-switching semiconductors in parallel to a converter (1) on the input side. The actual value of the current measured on the input side is fed in both converters (1, 2) to an adding device (7, 8) connected to a current regulator (9, 10) which is connected in turn to a control (11, 12) for the converters (1, 2). A reference current interfaced via a multiplier (14) with a reference sine wave (15) which is synchronised with the a.c. voltage applied to the converters (1, 2) is taken to the adding device (7) for converter (1). The difference between the actual and reference values at this converter (1) is taken to an inverter (16), the output signal of which is taken to the adding device (8) for the auxiliary converter (2) as a reference value. Unlike tuned impedance circuits, this arrangement not only impedes certain frequency components in the interference currents but also facilitates the compensation of any shape of curve through the high switching frequency of the auxiliary converter (2).

Abstract: The transmission system has an exchange terminating unit (COT) which can be connected to an exchange unit (EX) and is connected to a plurality of remote stations (RT1...RT3) via two optical, parallel-arranged lines (RL1, RL2). In the exchange terminating unit (COT), an incoming optical connection (RL1) is led to the further, outgoing optical line (RL2) in such a way as to form a folded ring network (FRN). Individual communication terminal devices of the communication network can be connected to the remote stations (RT1...RT3). In the event of malfunctions of the optical lines (RL1, RL2) or of the technical components (OR, OT) involved in transmission, a folded, configured ring network can be re-formed from the still intact ring network parts with the aid of switching means (LB1...LB3) and controllers (ZS, ST) arranged in the transmission system. The transmission system can be used particularly advantageously in communication networks extending over a wide area and can be adapted with regard to the requisite transmission reliability in dependence on the number of communication terminal devices to be connected. <IMAGE>

Abstract: With this device, it is possible to open the car door of an elevator car located in the region of a particular floor, together with a coupled shaft door, normally by automatic drive or, in a power cut, by hand. If the elevator car is located outside a particular floor, the car door remains locked. A control cam (15) arranged at the upper end of a door leaf of the car door is connected in an articulated manner to the door-driving device via a band-shaped drive means. The control cam (15) brings about a low-jolt opening and closing of the car door on the closing side and of a driving parallelogram (18) necessary for coupling the shaft door to the car door and connected to the control cam (15) by means of a pull rod (36).

Abstract: The invention relates to a method for the quantitative and qualitative optical detection of labelled molecules by time-resolved fluorescence spectroscopy. In the method, dyes or molecules labelled by one or more dye molecules (dye conjugates) are specifically coupled to biomolecules, toxic substances, polymers or pharmaceutical agents and characterised by the dye-specific fluorescence lifetime which is unaffected by the labelled molecule. The use of multiplex dyes (same absorption and emission behaviour but different fluorescence lifetimes) makes possible optimal characterisation, on the basis of their different fluorescence lifetimes, of various substances which are present in a mixture after specific labelling with multiplex dyes and with use of the same excitation light source and detection unit. Detection of the time-course of the fluorescence intensity (fluorescence lifetime) makes it possible to dispense with the filter technique hitherto used and to suppress temporarily the scattered light, which leads to an increase in sensitivity compared with the methods used at present.

The cartridge case (10) contains a cartridge (12) limiting a high-pressure space (21) in which a propelling charge (14) is located. The cartridge (12) is surrounded by a low-pressure space (10a) limited by the inside walls of the cartridge case (10) and a part of the base of the projectile (11). At the rear of the projectile (11) a tracer composition (11b) is arranged in a tube (27) which protrudes through the upper wall of the cartridge (12) into the high-pressure space (21). Projectile and cartridge case are interconnected via a rated breaking point (12d). The pressure for expelling the projectile (11) from the cartridge case is supplied by the pressure both in the high-pressure space (21) and in the low-pressure space (10a). Upon expulsion the volume of the high-pressure space (21) is furthermore enlarged when the tracer composition is pulled out thereof. These measures avoid steep pressure peaks in the march of pressure upon expulsion of the projectile. At the same time, approximately the entire projectile volume is available for a service charge.
