Abstract: An electromechanical adjusting device for pivotable head and/or foot parts of a bed frame with a pivot in the form of a rod movable with the pivotable part and extending transversely of the bed frame comprises a reversible rotary electric motor whose rotor shaft extends at right angles to the rod and drives a worm and worm gear and a pinion for driving the rod and itself driven by the worm and worm gear through spring clutch means, the adjusting device being supported by the rod.
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.
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.
