  • Light barrier or light grid with alignment mechanism
    Patent number: 7087884
    Abstract: A light barrier or light grid which has at least one light emitter arranged in a first housing and at least one associated light receiver arranged in a second housing. At least one emitter of visible alignment light installed in the first or the second housing generates one or more alignment light beams which is used to geometrically orient the light emitter relative to the opposite light receiver. For optically aligning the two housings, at least one alignment mechanism is present in the housing which receives the alignment beam. The alignment mechanism has at least one surface which optically deflects the alignment beam towards a target plane.
    Type: Grant

  • Heat-exchanger tube structured on both sides and a method for its manufacture
    Patent number: 6488078
    Abstract: The invention relates to heat-exchanger tubes structured on both inner and outer sides with excellent heat-transfer characteristics, which have recesses on the outside and ribs with specific dimensions on the inside. The structuring tools utilized for the various method modifications are adjusted in such a manner that they are not only able to create aligned, continuous grooves and non-aligned, spaced apart recesses but also secondary structures. The heat-exchanger tubes provided preferably with smooth end sections and smooth intermediate sections are utilized in particular in shell and tube heat-exchangers.
