Patent DE-2617744-A1 (DE)
Title: Catalyst for reducing nitrogen oxides in gas mixt. with ammonia - contg. oxides of titanium, tungsten, molybdenum, vanadium and opt. tin
Inventor: WATANABE YOSHIHISA
IPC: B01D53/94
Filed: 1976-04-23
Abstract: Catalyst for reducing nitrogen oxides in exhaust gases to nitrogen by contacting the exhaustion gases with gaseous ammonia, contg. a mixt. of oxides of Ti, W and/or Mo, V and opt. Sn is improved in that it contains (in atom %) Ti >=50% (pref. >=70%), W and/or Mo =50% (pref. =30%), V =1%, and Sn 0-10% (pref. =1%). The catalyst compsn. pref. contains 60 wt.% or more of a solid carrier. Purification of exhaust gases from internal combustion engines, combustion furnaces, industrial plants producing or employing HNO3 or nitrates, etc., is improved by selective catalytic reduction of even small amts. of NO and NO2 to N2 with NH3 without side-reactions with other components of exhaust gases such as O2, CO2, CO, water vapour or sulphur oxides. The selective action of the catalyst can be ascribed to the use of a small amt. of V in a narrow concn. range. The reaction proceeds in a wide temp. range (150-650 degrees C, pref. 150-550 degrees V). The catalyst has high activity and long service life.

Title: Measuring tool for dimensions of object - uses carrier force detectors and computer to determine one or two dimensions and weight of body
Inventor: GASSMANN HELMUT DIPL ING DR IN
IPC: G01B7/004
Filed: 1977-03-28
Abstract: The tool is designed to check the one dimensional measurement of a body (1) such as a rod or tube.

Patent DE-2744879-A1 (DE)
Inventor: HILDEBRAND EDUARD
IPC: A47L15/24
Filed: 1977-10-05
Abstract: The supporting element of a first endless conveyor (4) is guided about deflection wheels (12) which are arranged between two supporting discs (43) which are supported by the same shaft. Beneath the first endless conveyor (4) there is arranged a second endless conveyor (14) which conveys articles in the same direction. Above the supporting discs (43) and the deflection wheels (12) there is arranged an auxiliary conveyor (30). The latter has two conveying elements (31) which engage in the two longitudinal edges of the trays (5) which are made to tip by means of the two supporting discs (43). The said conveying elements (31) release the inclined tray (5) into a position in which it is aligned with the bow-like holding devices (19, 20) of the second conveyor (14). The tray (5) which moves towards the second conveyor (14) by means of a free-fall therefore adopts a position in which it is aligned with the holding devices (19, 21), so that the trays (5) are no longer damaged despite continuous operation of the apparatus. <IMAGE>

Title: Adjusting universal rolling mill to required rolling line - where I=beams with symmetrical shape can be rolled independently of width of flanges on beam
Inventor: SVAGR ALEXANDR
IPC: B21B31/04
Filed: 1977-12-03
Abstract: During the rolling of I-beams, it is necessary to adjust both the vertical and horizontal rolls vertically. The two horizontal rolls are each located in chocks mounted on a transverse; and the traverses are located on tie rods so they can be moved vertically w.r.t. the bedplate of the mil. On the bedplate is an intermediate plate employed to support a frame carrying the two vertical rolls. The frame can be lifted w.r.t. the plate, so that packing pieces of different thickness can be inserted between the frame and plate, thus altering the height of the vertical rolls. I-beams with a symmetrical shape can be rolled independently of the width of the flanges on the beam.

Title: Heat insulated composite window profile - is made by extruding metal profiles, drawing insulating bar into grooves and pressing stem over
IPC: E06B3/273
Filed: 1977-12-14
Abstract: Two metal profile pieces and an insulating bar are combined to form the heat-insulated composite profile, together with two groove stem pieces forming a groove for the bar. A metal profile (1) is made by extrusion, with continuation (4) and one groove stem piece (3) in a position further away than that of the complete composite profile from the insulating bar (5). The bar is drawn into the grooves (6, 7) in the two metal profiles (1, 2). The first groove stem is deformed and pressed onto the bar so that the continuation takes up the requisite position for the complete unit. This process enables rolling-in to take place from outside.
