  • Method for processing an olefin-containing product stream
    Publication number: 20050222478
    Abstract: A method is described for processing an olefin-containing product stream (1) that contains, besides ethylene and propylene, longer-chain olefins and compounds of hydrocarbons with oxygen (oxygenates). Such a product stream (I) can occur in particular in olefin synthesis from methanol. The product stream is dewatered in successive process steps, optionally compressed in several steps and dried. Then it is subjected to fractionation. For removal of the undesired oxygenates it is proposed that the oxygenates be washed out of the gaseous product stream after the compression steps and before the drying step in a column (12) with methanol.

  • Rotary light switch
    Patent number: 6894242
    Abstract: The rotary light switch for motor vehicles has a housing (10) and an actuating member (14) mounted rotatably. In a peripheral wall (24) of the housing, a cam surface (26) is recessed, which runs in peripheral direction and rises axially facing axially away from the actuating member. A cam follower (22) projects radially from the actuating member (14) and runs up on the cam surface on rotation of the actuating member, bearing only axially on the cam surface and forcing the actuating member (14) to move axially.

  • Method and device for detecting substances in body fluids by Raman spectroscopy
    Patent number: 6868285
    Abstract: The invention relates to a method and to a device for the non-invasive detection or determination, by Raman spectroscopy, of the concentration of substances in body fluids. The aim of the invention is to facilitate a non-invasive in vivo detection of substances in body fluids that allows for very accurate, reproducible results of analysis while requiring only little time for measuring which is acceptable for the patient. To this end, the inventive method and device for carrying out a Raman spectroscopy of a body fluid in a body tissue (1) records at least two Raman spectrums under different physical conditions and compares them with each other. The result of comparison allows detection of the substance one is looking for and measurement of the concentration of said substance.
