Title: Atmospheric carbon di:oxide fixed with valuable substances
Inventor: WAITZ EDGAR
IPC: B01D53/85
Filed: 1994-04-29
Abstract: CO2 in the atmos. is fixed by using a synthetic polymer reaction filter (11). H2O acts as a hydrogen donor and CO2 as hydrogen acceptor. Alternatively another sieve-like or channelling type, porous or coated reaction material can be used which has aperture sizes, migration distances or space between coatings which are up to the micron range. The walls or contact surfaces attract H2O molecules very strongly so that a reaction occurs in which H2O or H2O vapour impinges on the reaction material. Also claimed is a device for carrying out the reaction consisting of a reaction filter (11) in the form of an endless belt, a carrier (12), enclosing a water tank (13), a steam drum (16), running pulleys (14) and guide pulleys (15), to remove the reaction prod. from the filter (11), a tensioning device (17) for the filter (11) and a drive device (18).
Patent DE-4418427-A1 (DE)
Title: Air-flow guide mechanism for a compressor inlet
Inventor: YAGI YOICHI
IPC: F04D29/66
Filed: 1994-05-26
Abstract: The invention relates to a compressor which comprises a rotary shaft, an impeller which rotates about the shaft in order to compress air, and an air inlet with a circular cross-section, centred on the rotating shaft, to provide air for the impeller. Also provided are a multiplicity of movable guide blades, which are in each case rotated in an inlet near the outer periphery of the circular cross-section, and a mechanism for tilting the movable guide blades, and a mechanism for causing a particular movable guide blade to project further downwards than the other movable guide blades. If a circular air flow is produced by the movable guide blades, Karman vortices are produced by the rear ends of the guide blades, and if the phases of these vortices join together, noise is produced. A particular movable guide blade whose rear end projects further downwards than the other guide blades interrupts and disturbs the phase combination of the Karman vortices produced by the other guide blades and thereby prevents noise. Since the particular guide blade is tilted in the same direction as the other guide blades, the guide blades do not get in the way of one another. Consequently, the guide blades can be arranged at any desired interval from one another. In addition, tilting limits and the direction can be set as desired.

Patent WO-9201884-A1 (WO)
Inventor: SCHABERT HANS-PETER
IPC: F16H25/20
Filed: 1991-07-24
Abstract: In order to protect a spindle (2) rotated in a fitting by a spindle nut (6) rotating in a housing (4), the invention calls for a braking device for the spindle nut (6). When a given reference force is exceeded, two facing friction surfaces (11, 13) are pressed towards each other against the spindle (2) to exert a braking force. One friction surface (13) is rotationally secured with respect to the spindle nut (6), while the other friction surface (11) is rotationally secured with respect to the housing (4). The invention calls for the spindle nut (6) to be spring-mounted by a spring washer assembly (50, 51) in at least one longitudinal direction, the braking force acting through this assembly on an intermediate radius (ro) relative to the width (r1 - r2) of the assembly. The fraction of the total spindle force which acts as a braking force is thus increased.
