Patent DE-19638574-A1 (DE)
Title: Power supply for rail vehicle with at least one DC-fed power converter
Inventor: DIHLMANN THOMAS DIPL ING
IPC: B60L9/00
Filed: 1996-09-20
Abstract: The power supply has at least one DC-fed controlled converter. In the current control circuit is at least one filter with a band stop characteristic which has a frequency range that damps or suppresses interference currents. The converter is a DC power converter and has a voltage control circuit with an underlying current control circuit. The latter especially has a shorter reaction time than the voltage control circuit. Outside its characteristic frequency the filter has no amplitude or phase shifting of consequence. The filter is subject to actuation signals. It is located between the secondary output of the converter for measuring the actual current value and the summing point for the formation of the actuation signal.

Patent DE-19642839-A1 (DE)
Title: Removal of radioactive contaminants from aqueous mining effluent
Inventor: GOHLKE ULRICH DR RER NAT
IPC: G21F9/12
Filed: 1996-10-17
Abstract: A method for immobilising radioactive contents of water, especially for removing caesium 137, strontium 90, uranium and plutonium compounds from water, comprises a single step process which uses an organic polymer aggregate with amide oxime and hydroxamic acid groups to separate uranium and plutonium and also uses aluminosilicates to separate alkali(ne earth) metals. Contaminated water is added continuously and both effluent water and sludge are continuously removed. The sludge waste product from this process is converted into a glass to prevent radioactive substances being leached out.The apparatus used in this method is also claimed.
Patent DE-19644502-A1 (DE)
Title: Grab device for micro assembly of small workpieces
Inventor: WAGNER THOMAS DR
IPC: B25J7/00
Filed: 1996-10-25
Abstract: The device consists of two grab elements, each with a grab jaw section and a lever arm section. The lever arm sections are charged by a movable power-transmitting element, which is tensioned against the lever arm sections by a tensioner device. An actuator is formed by a piezo adjusting element, which is charged by an electrical control voltage. This lengthens the element in the direction of the lever arm sections, so that it presses against the power-transmitting element, which in turn is driven in the direction of the lever arm sections. This causes the grab jaws to move about joints, and towards each other.

Title: Analogue filter circuit for use in PAM data receiver system
Inventor: FRIESKE SVEN-OLAF
IPC: H04B15/04
Filed: 1996-12-04
Abstract: The circuitry consists of an analogue filter (3), as part of a receiver (9), two analog switches (1, 2), and a micro-controller (6) with an oscillator (7) and auxiliary oscillator. The analogue switches are coupled to the filter and the oscillator inputs (4, 5) of the controller.

With the receiver deactivated, the analogue switches are made to connect the filter to the oscillator inputs of the micro-controller. If coupled to the filter, the oscillator operates at the filter resonance frequency and serves for generating a time base.
