  • Patent number: 7033558
    Abstract: The invention refers to a method for removing traces of hydrocarbons, particularly propane, from gas flows. The conversion of hydrocarbons into carbon oxides is achieved by loading suitable carrier materials, such as e.g. TiO2 or Al2O3, with ruthenium as active component, possibly doping them with one or more further element(s), and subsequently calcining and/or reducing them at an increased temperature. By means of these catalysts, and at 20 to 150° C. and while adding molecular oxygen, hydrocarbons, particularly propane, in concentrations ranging from 0.1 to 2,000 ppm are oxidized.

  • Patent number: 7001021
    Abstract: A device for projecting a color image upon a screen, including color image recording and color image reproduction with an enhanced color reproduction trueness in comparison to conventional processes. In the device two images are recorded in parallel, which separately detect the shorter and the longer wavelength parts of the individual principle color spectral regions. In image reproduction six primary valences are produced, which respectively comprise the image information of the shorter and the longer wavelength parts of each of the individual principle color spectral regions. In an alternative embodiment the device produces a full color, stereoscopic image reproduction, in which the three primary valences of the respective shorter wave part encode a stereoscopic half image and the three primary valences of the respective longer wavelength part encode the other stereoscopic half image.

  • Patent number: 6996253
    Abstract: The invention concerns a device for improving the view in vehicles, in particular at night, bad weather and fog. In the process images of actual traffic scenes are recorded by a camera (2), which is sensitive outside the visible spectrum, and these images are reproduced in the visible spectrum in the vehicle via a display optic (6). According to the invention the type of object which is contained in a traffic scene recorded by the camera (2) is automatically classified according to type, and depending upon the type of the recognized object it is reproduced on the display optic (6) in an intensity and/or color, which corresponds to the intensity and/or color which the associated object typically has by daylight. The process facilitates the recognition by the vehicle operator of images of traffic scenes recorded outside the visible spectrum.

  • Patent number: 6994518
    Abstract: A pre-whirl generating apparatus (26) is provided that employs deformable air deflecting vanes (46) adjacent the inlet (18) of a radial air compressor (12-22), which vanes (46) can be mechanically deformed to generate positive, neutral, or negative pre-whirl flow to the compressor. A minimum number of parts are used to position one or more thin, deformable vanes (46) in the intake channel (34) leading to the compressor inlet (18). In their undeformed position, the vanes (46) do not deflect the incoming air, thereby causing little or no flow restriction. To achieve the desired positive or negative pre-whirl of flow to the compressor (12-22), the trailing edge (62) of the vanes (46) are deflected transverse to the direction of flow in the channel (34) in either the positive or negative direction.

  • Patent number: 6994458
    Abstract: The invention concerns a process for operation of a vehicle headlight as well as a vehicle headlight (1) with a housing and a light source (3) provided within the housing. In accordance with the invention the housing of the vehicle headlight (1) is designed to be pressure-tight and the headlight (1) is associated with a controller (7), which controls the headlight (1) depending upon the pressure within the housing. The controller (7) brings about that the headlight, depending upon the pressure within the housing, is switched off, is adapted in its light intensity and/or is changed in its emission characteristic. Thereby a headlight is produced characterized by being safe for the eyes.
