Patent DE-3246144-A1 (DE)
Title: Circuit arrangement for keeping a current constant
Inventor: MESCHKAT PETER DIPL ING
IPC: H04M19/00
Filed: 1982-12-14
Abstract: It should not be possible to overdrive a transistor, the collector-emitter path of which is connected in series with a variable load resistance and an emitter resistor to a voltage source and the base of which is connected to a source of constant reference voltage, due to increased load resistances even outside the constant current range so that, seen from the load resistance, the high impedance of the circuit arrangement is retained. For this purpose, an overdrive protection device is provided which monitors the collector voltage and below a minimum collector voltage still providing for the nominal constant current forms a base series resistance increasing from zero. The invention can be advantageously used in balanced feed circuits for telephone subscriber lines. <IMAGE>
Patent DE-3246365-A1 (DE)
Title: Notch antenna for a wide frequency band
Inventor: STOFFEL MANFRED ING GRAD
IPC: H01Q7/00
Filed: 1982-12-15
Abstract: Notch antennae consist either of a cut in a metallic structure or of an electrically conductive frame on a metallic body, and of a tuning capability to a specific frequency. This is implemented according to the invention in that the connecting cable is connected at the one end to the notch antenna, i.e. in the region of the open end in the case of a cut, and at its one end in the case of a frame. Connected in parallel with the connecting cable is a capacitor whose value is changed as a function of the frequency band in order to compensate for the reactive components of the antenna internal impedance. In the region of the opposite end, i.e. in the inner part in the case of a cut and at the opposite end in the case of a frame, a terminating reactance is inserted whose value is likewise changed as a function of frequency such that the resistive components of the antenna internal impedance has the desired magnitude. The latter may consist of the parallel connection of variable capacitances and a connected inductor. The capacitances are formed by capacitors which can be connected in parallel and can be switched, for example, by PIN diodes. <IMAGE>

Title: Process for the electrochemical treatment of wastewaters and arrangement for carrying out the process
Inventor: ZENIN GENNADIJ SERGEEVIC
IPC: C02F101/00
Filed: 1983-04-05
Abstract: The process for the electrochemical treatment of sea water-containing wastewaters (effluents) includes the recovery of a coagulant in the interelectrode space between insoluble and soluble electrodes of a diaphragm electrolysis cell and the subsequent discharge of the purified water. According to the invention, the coagulant is recovered in the interelectrode space by passing a current through only the insoluble electrodes, the current strength of which is sufficient to displace the potentials of the soluble electrodes to the range of their active dissolution, while the total concentration of coagulants in the interelectrode space between the insoluble and soluble electrodes is constant, which the self-regulation ensures. The arrangement for carrying out the process contains a diaphragm electrolysis cell having two or more electrode pairs, each of which is composed of a bottom insoluble electrode (2) and a top soluble electrode (3), which are arranged axially to each other. According to the invention, in each electrode pair, the insoluble electrode (2) is separated from the soluble electrode (3) by a dielectric intermediate layer (4), the outline of which coincides with an end surface of the insoluble electrode (2) which faces the soluble electrode (3), the length ratio between the soluble electrode (3) and the insoluble electrode (2) being at least 1 : 2. <IMAGE>

Title: Device for testing the flow resistance of filters
Inventor: WASCHMANN MICHAEL DR
IPC: G01F5/00
Filed: 1983-08-25
Abstract: Filters for cleaning air are used in respirators and medical breathing apparatus, to protect against the effects of dust and bacterial contamination. Their flow resistance becomes greater as they progressively become charged; the filter must be exchanged or cleaned. A device for monitoring the flow resistance must be provided and be easy to handle. It comprises a pressure line, which can be connected to a test-gas supply and onto which the filter to be tested is fitted. In the form of a T-piece, a flowmeter with a float and outflow of the flow air to the outside is connected to this pressure line. A restrictor in the pressure line between supply-air connection and flow meter determines the test-gas rate. A flow-setting screw upstream of the filter connection divides the test-gas stream into part-streams through the filter and the flowmeter. After setting the lowest flowmeter part-stream, the filter to be tested is connected. The flowmeter part-stream which comes about due to the additional filter resistance is greater. The extent to which it differs, which can be read off from the float, is the increased filter resistance.
