  • Cyclone separator and separation method
    Patent number: 8657932
    Abstract: A separator comprises a separation chamber (1) with at least one inlet (11a) in its upper part, a solids outlet (12) in its lower part and two outlet pipes (2 and 3) for fractions of gas. Also described is a method which the separator uses, with the fractions of gas being sucked out in two separation zones generated inside the chamber, one with reverse flow and the other with unidirectional flow.

  • Elevator with an all optical control apparatus
    Publication number: 20050121264
    Abstract: An elevator with an all optical control apparatus having a control unit with a light source, a photodetector, an optical feeding fiber, and an optical feedback fiber. The light source is coupled to the optical feeding fiber and the optical feedback fiber is coupled to the photodetector. The all optical control apparatus further includes a member that can be manually actuated. The member has a fiber input and a fiber output. The fiber input is optically coupled to the optical feeding fiber and the fiber output is optically coupled to the optical feedback fiber. The member, when actuated, influences a light path between the fiber input and the fiber output in a manner that is detectable at the photodetector.
