Title: Material treatment method and apparatus
Inventor: OGILVIE GRAEME J
IPC: B01D53/32
Filed: 1993-06-25
Abstract: ABSTRACT     A method of treating waste material which involves creating a substantially continuous curtain of plasma and directing  the  material  to  be  treated  through  that curtain.   An  electric  arc  is  generated  between  two electrodes which are separated by an annular space,  and the arc column is caused to rotate about the axis of that annular  space  so that  a  substantially  uninterrupted curtain of plasma bridges the space and extends around the circumferential  extent  of  the  space.   The direction  of rotation of the arc column is generally transverse to the direction  in which  that  column  extends  between the two electrodes, and material to be treated is fed through the curtain  in  a direction which is transverse to both the rotational  direction  and  the  direction  of  longitudinal extent of the arc column.  One of the electrodes may be of cylindrical tubular form,  in which event material to be treated  is  fed  into  the  region of the arc through the axial bore of  that  electrode.   The  other  electrode may have a cavity in alignment with the adjacent end of the tubular electrode which  serves  to  direct  material  in  a direction such as to pass through the plasma curtain.

Abstract: ARTICLE PALLETIZER/DEPALLETIZER                 Abstract of the Disclosure An article palletizer and/or depalletizer is disclosed.  During palletizing operations, articles on an article conveyor are diverted from the article conveyor at a first location and moved along a first path toward a discharge end where a sweep unit urges and leads the diverted articles onto a pallet by groups for storage with a retainer precluding article travel beyond the pallet.  During depalletizing operations, stored articles are urged and led from the pallet by groups by the sweep unit and a retainer unit along a second path separate from the first path to thus establish a flow-thru configuration with the articles being led to a second location of the article conveyor downstream from the first location where the articles are inserted onto the article conveyor.  The system and method are particularly useful for storing cans diverted from a high speed can production and/or handling line, and for later supplying stored cans, when needed, to the line.
