Title: Measuring longitudinal speed of strip insulating material - utilising time between detection of electrical charge measurement transducer signals
Inventor: DRYCZYNSKI KURT
IPC: G01P3/66
Filed: 1980-09-26
Abstract: The method is for measuring the speed of longitudinal motion of strip insulating material and involves electrically marking the surface of the material and continuously converting the markings into measurement signals. The measurement accuracy is independent of the surface charge magnitude and the measurements do not require a calibration against a standard foil. The moving foil is continuously discharged before high voltage pulses are applied at time intervals to two electrical charging strips simultaneously. The charges are then detected and converted into proportional measurement signals. The propagation speed is then determined from the time between the signals and the predetermined separation of the electrical charge strips of the pairs of charge strips. The speed is calculated automatically by a computer.

Title: RF input filter circuit of a tuner
Inventor: SCHURIG KURT
IPC: H03J5/24
Filed: 1981-03-10
Abstract: An RF input filter circuit (19) inserted between the antenna connection (8) and the input (3) of the RF input amplifier (2) of a tuner (1) comprises a tunable and switchable resonant circuit (6) and an antenna adapter circuit (7) which is connected downstream of the resonant circuit and which can also be switched to be set to a plurality of receive frequency bands. Seen from the antenna connection, the antenna adapter circuit has a base inductor (10) and a series inductor (12) which connects the antenna connection to the resonant circuit. The two inductors are formed from the series connection of two further inductors (L3, L4; L5, L6), the latter connection points (21, 22) of which are interconnected via a switching diode (D3). When the switching diode is in the conducting state, it connects in parallel the inductors (L4, L5) lying between it and, with a capacitor (C2) which lies in parallel with one of these inductors, forms a relatively broadband blocking circuit which is tuned to an interfering receive frequency band and with which the attenuating antenna resistor (Ra) lies in parallel via the small remaining base inductor (L3). <IMAGE>
Patent DE-3110020-A1 (DE)
Inventor: HUSSMANN PETER DR
IPC: A23F5/26
Filed: 1981-03-16
Abstract: The natural product is finely ground. A continuous extraction method allows the extraction from the finely ground natural product of the extractible component by means of extraction solutions of different concentrations through the counter-flow principle method; the extraction being carried out, at least with the most concentrated extraction solution, without a noticeable temperature difference; the extraction being moreover carried out so as to withdraw, with a view to dehydration, the part of solvent which is the most enriched with extracts, -after a last extract concentration-, and to add to the system a corresponding amount of fresh solvent in view of a new extraction step. The dehydration is carried out in the following way: the solution having the highest concentration of extracts is finely dispersed into a dry gaseous stream for drying, and precipitated in this form on a support (41, 42), where a dehydrated extract layer is formed; this dried layer is subsequently transformed into a product in granular form or an extract powder. Alternatively the drying gaseous stream is charged with damp during the extract dehydration and discharges subsequently again this water on an absorber (11). The absorber (11) itself releases the damp it is charged with during the passage of another hot gaseous stream; by cooling said other gaseous stream the water is released in the form of a condensate; this condensate is reused as a fresh solvent.

Title: Plant for purifying waste water
Inventor: BOEHNKE BOTHO PROF DR ING
IPC: C02F3/12
Filed: 1981-05-06
Abstract: The invention relates to a plant for purifying waste water (effluent). In its basic structure, the plant is composed of a mechanical clarification device for the mechanical purification of the waste water, an activation tank for a first activation stage, an intermediate clarification device, a nitrification stage equipped with a trickling filter apparatus, a denitrification stage, a secondary clarification tank and a device for conducting away and, if required, treating surplus sludge. The waste water to be purified passes from the mechanical clarification device into the activation tank and from the activation tank via the intermediate clarification device into the trickling filter apparatus and finally into the secondary clarification tank. The biocoenoses between activation tank and aeration tank are separate. The activation tank is designed as a very high loading activation tank. The trickling filter apparatus operates solely as a nitrification stage. Between the trickling filter apparatus and secondary clarification tank is arranged an unaerated mixing tank as a denitrification stage. Apart from water from the trickling filter stage, surplus sludge from the activation tank can be introduced into the mixing tank, by-passing the trickling filter stage. In order to operate the plant in such a way that it works with high purification efficiency in the purification of communal waste water, the activation tank of the first activation stage is installed for operation at an oxygen content of 0.5 to 1 mg/l and thus for partial oxidative degradation. Sludge supply in the intermediate clarification device can maintain the sludge in the first activation stage in the endogenous growth phase in which substrate respiration is established. <IMAGE>
