Abstract: An electrostatic precipitator is disclosed. The precipitatior comprises a conduit for the passage of particles in an air flow and means generating an electrostatic field substantially orthogonal to the air flow, and an ion supply, capable of charging said particles, in which the generating means comprise a point electrode and a two dimensional surface electrode, characterised in that the plane surface electrode comprises an ion source and the point electrode comprises a counter electrode and in that the counter electrode is earthed.

Abstract: An endless horizontal conveyor discharges cartons of necked bottles onto a horizontal tabletop aligned with the endless conveyor insuring carton-to-carton movement of the bottles beneath the discharge end of a gravity chute feeding a series of bottle carriers, individually supplied to the gravity chute from a nested carrier stack onto bottles. The carriers are pulled onto the bottles by movement of the cartons and the bottles carried thereby. A keeper plate adjacent the discharge end of the gravity chute and downstream therefrom insures contact between the tops of the leading end bottles in each carton and the leading end of the carrier. Movement of the carton-contained bottles pulls the carriers from the chute and deposits the carriers in proper position overlying the tops of the bottles to form six-pack or eight-pack groups.
