Title: Process for the absorption and final purification of pollutant-containing exhaust gases
Inventor: MEINEL SIEGFRIED DIPL ING
IPC: B01D53/56
Filed: 1986-07-16
Abstract: The invention relates to a process for the absorption and final purification of pollutant-containing exhaust gases which contain, as principal pollutant components, HCl, HP, SiF4, SO2, NOx and/or wettable dusts. Such pollutants are principally contained in the exhaust gases of refuse incineration plants, some in highly variable compositions and concentrations. The aim of the invention is to develop an effective process for the absorption and final purification of pollutant-containing exhaust gases which operates with relatively low technical and economic effort. The object is the development of an absorption process by which readily and poorly water-soluble pollutant components can be absorbed separately. According to the invention the object is achieved in that the exhaust gas is passed through two identical absorption columns connected one after the other, equipped with sieve trays, at a velocity of 2 to 2.5 m/s, the sieve trays of which columns have an open area ratio of 0.25 to 0.30 and the hole diameter of which is 5 to 10 mm in the top part and 10 to 20 mm in the bottom part, fresh water being added in the top part of the first absorption column and dilute acid being circulated in the bottom part, and in the top part of the second absorption column, 10 to 20% by mass of NaOH solution being added and in the bottom part alkaline salt solution being circulated.

Title: Reinforcing core comprising metal tubes for an externally stepped or conical plastic mast, and mast provided with such a core
Inventor: LANGMATZ HANS
IPC: E04H12/02
Filed: 1986-10-23
Abstract: Reinforcing cores comprising metal tubes have proved successful for externally stepped or conical plastic masts for street lights or park lights. According to the prior art, either welded-together tube pieces of different diameter or conical tubes are used for this purpose. They are expensive, have to be provided with openings, which reduce the cross-section, for the passage of the plastic and they are difficult to centre in the production mould. The invention thus proposes to construct the core from circular-cylindrical, unconnected tube pieces 6 to 9 which are located one above the other, decrease in diameter from the base surface 3 of the mast to the tip 4, overlap at a distance at mutually facing ends and are held, at a predetermined mutual radial distance, at a radial distance from mould core 10 and the mould outer part 11, and over the overlapping length 12, by plastic retaining and spacing pieces 13 which are distributed uniformly over the circumference, can be plugged onto mutually facing tube-piece ends, receive said ends in a sliding manner and are in the form of S-hooks. <IMAGE>

Patent DE-3702133-A1 (DE)
Title: Photosensitive film
Inventor: DREXHAGE KARL HEINZ PROF DR
IPC: G03C7/02
Filed: 1987-01-24
Abstract: Known photosensitive films for the photographic bleaching method must be washed with water after exposure in order to remove the sensitiser. However, this is still too inconvenient with the known films. In addition, the known films harden relatively quickly after production, losing photosensitivity. The invention has the object of providing films with a longer shelf life whose sensitiser content can be washed out more rapidly. In order to achieve the object, the film contains a polyether and/or polyhydroxyl compound which has low volatility or is non-volatile at room temperature and pressure and is sufficiently soluble in water and the organic binder solvents.

Title: Arrangement for accepting and determining and delimiting the masses of liquids, especially for drinks such as milk or beer
Inventor: MIETH HANS OTTO DIPL ING
IPC: G01G19/08
Filed: 1987-06-13
Abstract: The invention relates to an arrangement for transferring and determining and delimiting the masses of liquids, especially for drinks such as milk or beer, according to the subject matter of the main application P 3545160.2-53, the liquid being transferred from at least a first container into at least a second container and in this process, in order to permit the gravimetric determination and delimitation of its mass, initially conveyed into a measuring container which is arranged upstream of the second container, the liquid preferably being measured there by means of a force-measuring device having a liquid inlet leading to a liquid outlet leading from the measuring container, by means of which the measuring container can be filled from the first measuring container on one side and emptied into the second container on the other, and with conveying devices for generating those differences in pressure in the inlet and the outlet which are necessary for conveying the liquid. An arrangement of this type ensures that determination of the weight of the liquid stored in the measuring container is carried out with even greater accuracy and substantially free of the effect of external and internal forces which distort the measuring results. This is achieved, among other means, in that the measuring container (1; 2, 3) is only free to move with respect to the supporting surface (21) in the direction of its weight components (FH<*>) which can be measured by the force-measuring device (18), in that the inlet pipe section (4a) for the inflow into the measuring container (1; 2, ...

Title: Apparatus for collecting samples
Inventor: WILLNER HELGE PROF DR
IPC: G01N21/35
Filed: 1987-11-05
Abstract: As connecting element between a gas chromatograph and an IR spectrometer, use is made of apparatus having a cooled carrier (support) (30) on the surface of which are deposited the substances brought from the gas chromatograph, where they can then be spectroscopically examined. The examination of a new sample requires the evaporation of the previously deposited substances. The heating and recooling of the carrier (30) required for this purpose has hitherto taken a very long time. Furthermore, the heating of the carrier was limited to temperatures at which not all substances could be completely removed from the surface of the carrier. By means of a thermal decoupling of carrier (30) and cooling apparatus (5, 7) it is possible both to heat the carrier (30) to higher temperatures and to reduce the time required for a measurement cycle, because such decoupling results in no heating of the cooling apparatus (5, 7), but the heating remains limited to the small mass of the carrier (30). Possible forms of a separable thermal coupling comprise a separable, heat-conducting mechanical connection (44, 92), a gas flow which can be switched off or else transport of the carrier from a cooling zone to a heating zone. <IMAGE>
Patent DE-3740017-A1 (DE)
Title: Circuit arrangement for detecting markings
Inventor: STEPHAN WALTER
IPC: B41F33/00
Filed: 1987-11-26
Abstract: In known circuit arrangements for detecting markings on objects, a multi-stage design of the switching amplifier is necessary to ensure the functioning of the switching element. In spite of this circuit-technological and constructional expenditure, when scanning markings which cause only relatively small signal amplitudes, difficulties arise with respect to their unequivocal identification. The novel circuit arrangement is intended to make it possible in a simple way, by suppressing interference signals (residual signals), that relatively unsharp markings can also be detected reliably. To compensate for the transparency of the object to be scanned (13), the circuit arrangement is provided with a further photoelectric device of a similar type, whose output voltage is fed as reference signal UE2 to the input of a differential amplifier (15), at whose other input the output signal UE1 of the photoelectric device on the scanning side is present (Fig. 1). <IMAGE>
