  • Molding method with automatic fluid treatment of mold cavity
    Patent number: 4064208
    Abstract: Two mold halves together form a mold cavity and one of the mold halves is fitted with a plurality of ejector rods that can be reciprocated so as to push a molded article out of that half. At least some of these ejector rods are formed with throughgoing passages terminating adjacent the inner ends thereof at nozzle openings. Air and a treatment fluid, such as a demolding liquid, can be injected into the mold interior through these rods, the nozzle openings in the ends of the rods being covered during the normal molding operation.
    Type: Grant

  • Stator for electric motor
    Patent number: 4053800
    Abstract: An electric machine has a stack of stator plates forming a central throughgoing passage defining an axis and having an array of inwardly open and insulated axial grooves in the passage. A plurality of stator coils together form a tubular stator winding have a generally cylindrical central portion lying in the grooves, one end portion formed as a dome with a central aperture at the axis to one axial side of the stack, and another end portion of cylindrical slope to the other axial side of the stack. The domed end portion of the stator coil is secured together and physically stabilized by means of insulating lacquer and/or a domed insulating cage received within the domed end portion and mainly of smaller inside diameter than the outside diameter of a rotor within the stator coil.
