摘要： The present method and apparatus for die casting of metals such as aluminum, is especially suitable for casting under vacuum. The casting is performed under such operating conditions that a contact between the molten metal being cast and the free atmosphere is avoided all the way from the melt to the casting proper. For this purpose, the present casting apparatus includes a closeable and evacuable transport container connected to the casting apparatus proper by a coupling which is also evacuable. The transport container is placed on a filling chamber and the evacuating apparatus is arranged to simultaneously evacuate the filling chamber, the transport container and the coupling between the transport container and the filling chamber proper. The evacuation takes place in a direction opposite to the flow direction of the metal being cast. If desired, further evacuating means may be provided for evacuation of the filling chamber and the die in the direction of the metal flow. The vacuum is switched off in response to the operation of a pressure piston after the filling opening of the filling chamber has been closed.

摘要： This apparatus relates to a workpiece transfer mechanism wherein a tiltable workpiece transfer arm has a free end. A workpiece gripping device is secured to the free end of the tiltable transfer arm by a piston cylinder arrangement. The piston rod supports the workpiece gripping device and the respective cylinder is secured to the free end of the transfer arm. The pressure in the cylinder is separately controlled on opposite sides of the piston in the cylinder to move the gripping device in response to the operation of workpiece handling stations between which the transfer mechanism is arranged. The piston is axially movable relative to the cylinder but rotation of the cylinder is transmitted to the piston to tilt the gripping device independently of any tilting of the transfer arm.

摘要： A multi-axle programmable manipulator is described which includes a corresponding multi-axle training arm for programming the manipulator. A support for the training arm is disclosed which allows the training arm to so be anchored to the manipulator that the first axle of the training arm extends constantly in the extension of the first axle of the manipulator. The displacement of the second axle of the training arm is mechanically compensated to be rotatable about the second axis of the manipulator.
