  • Label applicator
    Patent number: 4236954
    Abstract: A label applicator for an injection moulding machine which includes a suction head for picking up a label, an electrostatic charging device to electrostatically charge the label and means to reverse the suction to transfer the label to the face of a die where it is held by electrostatic forces. The label applicator also includes sensing pins which will actuate a switch to close down the injection moulding machine if the label is not correctly positioned to cover the sensing pins.

  • Labelling
    Patent number: 4218204
    Abstract: An attachment for an injection moulding machine which enables simple in mould labelling to be carried out. A moveable die face receives the label and the product is moulded onto the label. The moveable die face may be part of a rotary core attachment or a reciprocal sliding attachment to the injection die. The label is held onto the face of the die by electrostatic forces. Labels are applied to the moveable die face prior to its moving into alignment with the die and commencement of the moulding operation.

  • Circuitry for load connection and disconnection
    Patent number: 3940660
    Abstract: This invention relates to circuitry for the connection of a load to and disconnection of a load from an AC power source. The circuitry is specifically useful in the on/off control of such as incandescent lamps, but not exclusively so, and provides for the timed disconnection of a load when the load is connected in series with the circuitry and AC power source, or alternately provides for the timed reduction of power delivered to the load.
