Abstract: In order to be able to carry out a method for the removal of asbestos from electrical devices, such as, for example, night storage heaters, attached or located in enclosed spaces, with a comparatively small degree of expenditure and in order, as far as possible, to preclude risks for the disposal personnel and for the occupants of the room in which the device to be treated is located, according to the method the asbestos-contaminated device is set down on a moving base element (2) and the device is removed from its previous mounted position, possibly near to the wall, so that the device is enclosed by means of an at least partially transparent hood (4) which is placed over the device onto the base element (2) and has the devices for manipulation (16) of objects inside the hood (4), a partial vacuum is then produced in the hood (4), the asbestos-contaminated device is disassembled inside the hood (4) into parts which can be individually manipulated into handleable parts, the disassembled asbestos- contaminated parts of the device are packed into vacuum-sealed enclosures (22) inside the hood (4) and after removal from the hood (4) are taken to a disposal site for asbestos materials. In addition, the application relates to an advantageous device for carrying out the method. <IMAGE>

Abstract: In an incremental measuring system, periodic analog measurement signals, the fundamental shape of which is sinusoidal, are generated by scanning a measuring division (2) with a scanning unit (3), and from these signals, digital counting signals dependent on the direction of adjustment are derived by electronic subdivision of the scale in a divider stage (6) for an evaluating device (10, 11), each counting signal being allocated to a particular phase angle of the measurement signals. For the electronic correction of position errors, further signal levels offset by defined fractions of the division step are determined between the signal levels allocated to the counting signals and located at the phase spacing of the subdivision points and the evaluation of the measurement is optionally referred to the offset signal levels in accordance with a correction program, so that corrections are performed in correction steps only corresponding to fractions of the division step. In a measuring system suitable for carrying out the method, comprising a divider circuit (6) in the divider stage and trigger and pulse shaper stages for generating the counting signals, two or more divider circuits (6 to 6c) with a mutually identical division factor but with a position of the trigger levels which is phase shifted by fractions of the division step with respect to one another with reference to the analog measurement signals, in which arrangement in each case one of the divider circuits can be connected to the evaluating device (10) via a selection switch (7) in accordance with a correction program.

Abstract: A balancing network of wave digital filter type consisting of three-terminal-pair conversion adaptors (21 to 26) connected in cascade each of which having a capacitor (C) and a resistor (R) as constituent elements to exhibit a filter operation function. Based on the fact that no wave is reflected by a terminal pair other than the two terminal pairs for cascade connection of the conversion adaptors (22, 24, 26) that include the resistor (R), the above terminal pair is excluded and these adaptors are combined with the neighboring conversion adaptors (21,23,25) that include the capacitor (C) in order to form a new three-terminal-pair-combined conversion adaptor (41) which realizes a filter function with an operation amount which is smaller than the sum of operation amounts of the three-terminal-pair conversion adaptors (21 to 26).

Title: Process for transmitting a colour television signal.
Inventor: EBNER ANDREAS
IPC: H04N9/77
Filed: 1990-11-08
Abstract: In order to prevent phase errors in the transmission of a colour television signal in time and frequency multiplex without taking account of image interference, a reference signal is inserted during image generation in at least one line of each complete image which contains no image information in its image blanking region. In the image blanking region of the line concerned the reference signal has a sloping component continuously rising with the amplitude on which a sine-wave oscillation with the frequency and phase of the colour carrier is superimposed. Throughout studio processing and broadcasting at the transmitter to preparation at the receiver, the reference signal remains inseparably linked to the image information of the appropriate complete image.

Abstract: A pressure pulsation absorbing device adapted to be connected between a pair of piping flanges is disclosed. The device comprises a cup shaped silencer box having a central inner bore for fluid flow therethrough, and a plurality of water stop bosses integrally formed with the silencer box around the inner bore through which piping bolts are inserted. An elastic cylindrical body is provided in the silencer box around the water stop bosses to thereby divide inside space of the silencer box to a radially inward fluid flow section and a radially outward dry section. A plurality of threaded bosses are integrally formed with the silencer box in the dry section for receiving bolts for fixing a side plate covering a side opening in the dry section. A slight clearance is provided respectively between outer surfaces of the water stop bosses and an inner circumference of the cylindrical body and, between outer surfaces of the threaded bosses and an outer periphery of the cylindrical body. The pressure pulsation is absorbed by expansion and contraction of the elastic cylindrical body. However, such expansion and contraction is limited within the range of slight clearances and, therefore, breakage of the elastic cylindrical body is prevented.

Abstract: The process of this invention will remove from acid rain essentially all of both the sulfur oxides (SOX) and nitrogen oxides (NOX) by catalytically reducing the NOX to water and elemental nitrogen and the SOX to either H 2 S or elemental sulfur as desired. The process employs specific catalysts in the heteropoly acid or salt group and the spinel or inverse spinel group. The process conditions achieve an oxygen-free environment and reduction is effected with stoichiometric to 100% excess above stoichiometric H 2  or H 2  and CO as reducing gas. Temperatures can be 200° to 900 C with the lower temperature range being favored; space velocity can be 2000 to 20,000 and still achieve 95+% abatement. The only product of the reaction which must be disposed of is saleable elemental sulfur.

Abstract: The process for low-emission drying of a substance in a drum-type drying installation is suitable in particular for sewage sludge, fish meal and sludges from starch factories, soap factories and paper mills, which substances are preferably to be converted into granules. The process is likewise very suitable for drying biomass products such as wood chips, grass, sugar beet chips and the like, since the emissions are very greatly reduced by means of this process. The drying process is carried out in such a way that no unpleasant odors and dusts are emitted to the outside, because the actual drying circulation is closed. Fossil fuels are used as the heat source for the burner for heating this air stream.

Abstract: This invention relates to a bias current control circuit which drives a power MOS transistor. Since the power MOS transistor has a large capacitance which is formed between a gate and a channel, it is needed to provide a circuit which is able to sufficiently supply a drive current to the gate. Such a circuit increases a consumption current because the circuit has to always flow the current to drive the gate. This invention provides a circuit which cut the consumption current in the circuit when the transistor is not driven, and increases a consumption current in the circuit in order to keep a gate current when the transistor is driven.
