Patent DE-3531968-A1 (DE)
Title: Simultaneous scrubbing of SO2 and NOx having an intermediate step
Inventor: HOELTER HEINZ DIPL ING
IPC: C01F11/48
Filed: 1985-09-07
Abstract: It is known to purify SO2 and NOx from combustion exhaust gases by use of a wet scrubbing circulation whose scrubbing water contains iron II-EDTA or iron II-NTA complex. To retain the iron II complex within the scrubbing solution, reducing agents are added or scrubbing water treatments are carried out in the by-pass in order to reduce again the iron oxidized by the atmospheric oxygen from iron II to iron III in the chelate complex and thus to prevent the use of expensive reducing agents. In order further to improve the process according to the main application P 3525051.8 using sodium and/or calcium formate, according to the invention it is proposed that the scrubbing liquid is contacted with the SO2- and NOx-containing gas at a pH below 6, preferably between 4.3 and 4.8, and from this, a portion of the scrubbing water is reduced to a pH around 1.5 by sulphuric acid for EDTA precipitation and by introduction of SO2-containing gas, the reduction phase from FeIII sulphate to FeII sulphate is initiated. The liquid thus treated is returned to the active scrubbing circulation.

Title: Sealing device with a gas-lubricated mechanical seal
Inventor: SCHLIERMANN ERICH DIPL ING
IPC: F04B39/00
Filed: 1985-09-23
Abstract: A known gas-lubricated mechanical seal (axial face seal) which exhibits considerably smaller leakage losses than labyrinth shaft seals, is modified so that it can be used at extremely high pressures, temperatures and peripheral speeds. In the sealing device, sealing faces (1, 2) are arranged on slip rings (4, 6), depressions (1') resembling radial blades being formed in the sealing face (1). In the rotational speed range in which a hydrostatic gas lubrication film has not yet formed, the sealing faces (1, 2) have a predetermined gap; in the other rotational speed ranges, the sealing faces (1, 2) slide on one another with gas lubrication. This prevents the occurrence of dry friction and both slip rings (4, 6) can be produced from hard, stable materials. This gives a mechanical seal suitable for extreme stresses (Fig. 1). <IMAGE>

Patent DE-3544238-A1 (DE)
Title: Hydraulic lifting device, in particular a column hoist for vehicles
Inventor: BOECK HANS DIPL ING
IPC: B66F7/20
Filed: 1985-12-14
Abstract: A hydraulic lifting device with two lifting units working in synchronism is proposed, of which each lifting unit has a differential cylinder and a single-acting plunger cylinder. The disc-piston surfaces on one side of the differential piston of the differential cylinders are fed by a common hydraulic pump. The plunger cylinder of one lifting unit forms with the differential cylinder of the other lifting unit a synchronous pair and a pressure balance. The working space of the plunger cylinder is connected via a connecting line to the annular space of the differential cylinder, allocated to it, of the other lifting unit and is fed from this annular space. The piston surface of each plunger piston, which piston surface can be acted upon by hydraulic fluid, is identical in area to the annular surface of the differential piston of the allocated differential cylinder so that the lifting rods of this pair are in each case extended in synchronism. Each cylinder pair also regulates the synchronism of both lifting units even during varying loading without the disadvantage of retardation through compressibility. At the same time, mechanical or suchlike auxiliary devices are dispensed with.

Abstract: The invention relates to an arrangement for separating sheet-shaped articles from a stack by means of a frictional drive and may be used preferably in bank note counting machines, automatic cash dispensers, document evaluation devices (document readers) and similar devices. With the aid of metal guide plates which are arranged so as to be inclined at an acute angle to the stack advance direction and at an acute angle to the take-off direction and support surfaces which are arranged above and below the metal guide plates, at the sheet longitudinal edges, a curvature is achieved in the longitudinal direction of the sheet-like articles. The braking forces occurring at the first sheet-like article, which are produced by friction between the first sheet and the contacting surfaces and by friction between the first and second sheet, are thereby minimised. The separation quality and the reliability are thus improved. <IMAGE>
