Title: Process for the connection of two bushings, especially act as pole tubes for electromagnets
Inventor: GIBAS CHRISTOPH
IPC: B22D19/04
Filed: 1984-12-21
Abstract: The process serves for the coaxial connection of two hollow-cylinder-like bushings (1,5) which especially act as pole tubes for electromagnets and which in the semifinished state can be telescoped together coaxially by means of an axially overlapping end section (3). The bushings are connected by means of a weld seam (10) arranged in a weld groove and having an essentially lower melting point than the bushings. The two bushings are rotated about their axis during the welding process of the weld seam, and the end section is twisted off after the solidification of the weld seam. In order to simplify the process steps and to substantially shorten the process, an annular weld body is set on one of the bushings, before the bushings are telescoped, on the side of the weld groove to be formed by these bushings. After the telescoping of the bushings, they are set in a rotation which presses the molten weld body outwards. This weld body is heated until molten and then cooled. <IMAGE>

Title: Curvature-measuring instrument
Inventor: LUDOWIG GEREON
IPC: G01B7/28
Filed: 1985-03-15
Abstract: The invention relates to a curvature-measuring instrument consisting of at least one elongated elastic member of specific and uniform thickness and having an electrical measuring device by means of which the curvature of the elastic member which is applied to a sample being subjected to curvature is measured by virtue of the fact that the expansions of the surface of the elastic member are a measure of its curvature and the electrical signal of the measuring device is proportional to the curvature of the sample. According to the invention, a plurality of elongated elastic members (4, 7, 9) made from wear-resistant material of specific and uniform thickness and high pressure resistance are to be located one above another in an axially parallel and plane-parallel fashion with a specific uniform spacing, and the expansions of the surfaces of the members which occur during bending of the elastic members are to be measured on at least one of the elastic members on the topside and underside thereof by at least two electrical expansion sensors (8), as a rule strain gauges, which generate an electrical signal which is independent of temperature influences and superimpositions of tensile and compressive stresses and is proportional to the curvature of the sample. <IMAGE>

Patent DE-3520398-A1 (DE)
Title: Method and device for notching out interference signals
Inventor: ARENS EGIDIUS DIPL ING
IPC: G01S3/86
Filed: 1985-06-07
Abstract: Due to their sound radiation, operating units generate interference signals in output signals of an underwater sound receiving system located on board. Filtering with respect to frequency also leads to a suppression of useful signals at the blocked frequencies in the output signals. This problem is prevented in the solution according to the invention in that one or a number of pick-ups for structure-borne sound are arranged at the operating units and spectra of the structure-borne sound are derived from their signals. The spectra of the structure-borne sound are used for notching out the lines of the structure-borne sound in the received spectrum of the output signals. This elimination of interference can be particularly advantageously used in passive sonar systems for direction-finding and/or locating water craft.

Patent DE-3617040-A1 (DE)
Title: Flue gas scrubber having integrated heat recovery for small boiler plants
Inventor: DOLATA TILO DIPL ING
IPC: F23J15/04
Filed: 1986-05-21
Abstract: The invention serves for purifying the flue gases or exhaust gases and for improving the thermal efficiency of boiler plants, predominantly of heating plants of houses and multiple dwellings and in industrial, commercial, administration and office buildings. The particular structural design of the gas scrubber makes it possible to free the flue gases from the pollutants, or greatly to reduce these, by a three-stage absorptive scrubbing. The gas is evenly wetted with a wetting liquor over the entire flow cross-section in a flue gas intake duct. During the spray absorption, the flue gas temperature is lowered below the water dew point (t < 43 DEG C). The flue gas is then scrubbed in two packing beds lying one above the other in the counter-current process. The scrubbing liquid becomes highly concentrated as a result of the particular drainage conditions of the scrubbing liquor in the two packing absorption stages and thus the requirement for fresh liquor is reduced by half. The flue gas is cooled in the flue gas scrubber down to approximately 25-30 DEG C. All of the heat energy released is utilised for preheating the fuels (oil, gas) and the heat transport media (heating water and utility water). The scrubber is completely composed of plastic (e.g. PVC). Corrosion problems are thus excluded.
