Title: Method and device for rectifying a disturbed flow
Inventor: KERKMANN WILHELM DIPL ING
IPC: F15D1/06
Filed: 1989-03-15
Abstract: The device comprises a rectifier (2) with a central body (6) which carries a number of radial walls (7) on its periphery. The walls (7) form rectilinear, elongated cross-sections for parallel filaments of flow. The velocity of the filaments of flow is substantially greater than that of the disturbed flow. This results in homogenising of the velocity profile combined with the degree of turbulence being evened out by the flow distribution, and in fact at minimum pressure loss. The requisite rectifier length is also short. <IMAGE>

Patent DE-3912613-A1 (DE)
Inventor: MESZAROS PAL
IPC: B01D11/02
Filed: 1989-04-17
Abstract: A sloping cascade (e.g. at 30 DEG  to the horizontal) is composed of a series of stages of the construction illustrated. Attached to the mixing/settling vessel 2 by tube 4 is a separate vessel 3, at the top of which are valves 12a, for supplying compressed air, and 12b, for connection to the atmosphere. The phases in vessels 2 are agitated by means of gas supplied by lines 18. After the phases have settled, valves 12a are opened, in sequence, from the lowermost stage up. This causes the lighter phase to spill over, through lower connection 5, to the stage under it. Closing valve 12a, and opening 12b, restores the liquid to its former position. The heavy phase is discharged from the top stage by air-lift 22 and then, in succession, the heavy phase is moved up from each stage to the next higher, where it may be introduced into either of vessels 2 or 3. Mechanical agitation may be used; pumps may replace air-lifts 22; the lighter phase may be expelled by introducing the heavier below it. Both phases may be liquid, or one may be solid. Exemplified is treatment of a cation-exchange resin with sulphuric acid. <IMAGE>

Patent DE-3914550-A1 (DE)
Inventor: HARTNACK WOLFGANG DIPL ING
IPC: H04N5/44
Filed: 1989-05-03
Abstract: A video signal with 1250 lines, line interlacing and 100 Hz picture frequency, transcoded from a video signal with 1250 lines, line interlacing and 50 Hz picture frequency is free from extensive flickering. However, interferences due to a moving interference pattern may occur independently of the content of the picture. By transcoding the video signal with 1250 lines, line interlacing and 50 Hz picture frequency in function of the movement into a video signal with 900 lines without line interlacing and 75 Hz picture frequency, extensive flickering is avoided and the moving interference pattern is appreciably reduced, with the same vertical resolution and approximately the same line frequency. Application to digital image-signal processing.

Patent DE-3920645-A1 (DE)
Inventor: WAGNER BERNHARD DIPL PHYS DR R
IPC: G01P15/08
Filed: 1989-06-23
Abstract: A device for measuring mechanical forces and dynamic effects can be manufactured by micromechanical processes. A movable mass (4) is deflected, by the action of a mechanical force, against the resistance of a restoring element (3). For many applications, such devices must be insensitive to excessive mechanical stress. In known solutions, overload protection is achieved by means of mechanical limit stops which restrict the deflection of the mass. The device of the invention has elements which mechanically limit deflections of the mass and which can be intregrated monolithically with the other elements of the device, rather than being an additional element. The elements are designed as interlocking tongues (5, 6, 8, 9) which have motion-limiting bridge structures (7, 10).
