Patent DE-19517874-A1 (DE)
Title: Inverter control circuit used in HF heating device
Inventor: HAN GYEONG HAE
IPC: H05B6/06
Filed: 1995-05-16
Abstract: An inverter control circuit for HF heating has a detector 300 for the current entering the inverter 200 from a mains-fed rectifier 100 with a microcomputer 400 receiving the detector's output signal. The microcomputer then gives out first and second ON signals as well as a timing signal to control the inverter's switching. There is a detector 500 for the inverter input voltage and which gives a resonance detection signal depending on a given time lag setting signal. The latter is given by a driver control circuit 600, which also gives first and second control signals in response to the resonance signal and the three microcomputer output signals. The inverter driver 700 gives the driver signals to the inverter in response to the driver control signals.
Patent DE-19519424-A1 (DE)
Inventor: KRANERT KLAUS DR
IPC: H02M5/45
Filed: 1995-05-26
Abstract: A power converter drive for working aggregates with a propeller characteristic, for example marine screw propellers, has a synchronous motor with one or two stator windings, frequency converters for feeding the stator windings from a three-phase network and a regulating and controlling device (36) for the frequency converters and synchronous motor (19) associated to a manually controlled speed of rotation set value regulator (38). The frequency converters may be designed as direct or indirect frequency converters. When they are designed as indirect frequency converters (22, 23), they have two current source converters (32, 33) interconnected in series, associated each to one stator winding and that consist each of controlled semiconductor switches in a three-phase bridge arrangement. A current inverter (34) at the motor side with controlled semiconductors in a three-phase bridge arrangement is connected by a direct current intermediate circuit to the power converters (32, 33). In order to improve the power factor in the medium to low range of speeds of rotation of the power converter drive, one current source converter (33) of each pair of current source converters (32, 33) interconnected in series is short-circuited by a control unit (37) when the speed of rotation of the synchronous motor (19) falls below a set speed of rotation down to a predetermined speed of rotation (threshold speed of rotation), reducing the voltage in the intermediate circuit of the frequency converter (22 or 23) that feeds the stator winding of the synchronous motor (19).

Patent DE-19544185-A1 (DE)
Title: Industrial heat exchanger with tube bundle inserts
Inventor: VENTER JUERGEN
IPC: F28G1/06
Filed: 1995-11-28
Abstract: Inserts twisted round the tube axis are designed as cleaning elements (26) which oscillate freely within the tube section with limited flexure. Each inserted element consists of a zigzag of coil spring of smaller outside diameter (DA) than the inside diameter (DI) of the tube (25). The cleaning elements are held to the tube plates (24) and the element ends (27) lead out and round the plate and here fixed in groups by an abutment bearing (29). Another type of cleaning element is fixed to a flexible plate which itself bears resiliently on the tube plate. In service, gas flow through the exchanger tubes at 10-15 m/s dynamically excites the cleaning elements which thus scrape the inside tube walls clean using the flexible plates if fitted to produce a periodic vibration and more effective cleaning.

Title: Twyman-Green interferometer adjustment device
Inventor: WEINGAERTNER INGOLF DR
IPC: G01B9/02
Filed: 1997-03-01
Abstract: The device includes a measuring surface area of a Twyman interferometer which forms the first surface area of an optical system arranged in the beam direction. The optical system contains an adjustment system, which represents an interferometer, whereby the centres of curvature of the measuring surface area and the surface areas of the adjustment system are aligned with each other. The adjustment of the Twyman interferometer is correctly achieved, if the structure of the interferogram which results from the adjustment system is optimized with respect to any other adjustment. For example, the adjustment is correct if the system minimises intensity modulation or reaches an extreme of an evaluation function after a mathematical transformation.
Patent DE-19709840-A1 (DE)
Title: Axis counting arrangement for rail-bound vehicle
Inventor: GRAF RUEDIGER DIPL ING
IPC: B61L1/16
Filed: 1997-02-28
Abstract: The arrangement distinguishes between frequency-modulated inductive sensor signals generated at a remote place and transmitted over signal conductors to an evaluation arrangement. The sensor signals are caused by eventual wheel influences, and are supplied to an input filter, by which they are prepared for the evaluation. A frequency-to-voltage converter (FSU1, FSU2) with at least one coupled trigger (T12, T22) is connected to the signal conductors (SK).  The threshold of the trigger lies below or above a signal level which settles in when the sensor is not influenced and when no noise is present. The trigger responds to an under- or overstepping of the threshold value. The output signal of the trigger is combined by an AND function with the output signal of a further trigger (T13, T23) which is connected at least indirectly to the output of the input filter, and which responds when the value falls below its predetermined threshold.
