  • Patent number: 8292540
    Abstract: A manhole assembly including a frame and at least a pair of cover plates that are receivable in and disengageable from the frame to permit selective closing and opening of an aperture, the periphery of which is defined by the frame. The cover plates substantially occupy the aperture when received in the frame. A first cover plate of a pair thereof is smaller than a second cover plate of the pair. The first cover plate is hingeable relative to the second cover plate, while the latter is received in the frame, from a closed position received in the frame to an open position in which a first part of the aperture is open.

  • Publication number: 20070138876
    Abstract: An electrical machine is described, having a stationary main element as stator and a rotating main element as rotor, of which one main element having a magnetic yoke and poles, of a predefined number of poles, projecting radially from the former, is made of SMC material and carries a pole winding on each pole. To achieve cost-effective manufacturing of the main element, the main element is assembled from at least two modules that are axially adjacent, rigidly connected to one another, and produced from SMC material, each module having a yoke part, closed in on itself, of the magnetic yoke having an equal number of divisions of poles attached thereto in one piece, which corresponds to a fraction of the number of poles determined by the number of modules.
