Abstract: A compact battery powered mover for heavy rollable loads, having a ventilated battery compartment incorporated into the body of the mover and a removable rechargeable ventilated battery that permits the replacement of a spent battery with a fresh battery at the work location. The mover also has incorporated into its compact design a motor controller that enables the use of a heavy current draw when needed for brief periods without developing excessive heating. The configuration of the critical components in and on the mover body permits the substitution of one critical component with another component having different operating properties without significantly changing the compactness of the mover.

Abstract: The invention is for a knife indexing apparatus for a non-rotating core cutting knife and a means for automatically indexing the knife during core cutting operations. The apparatus employs the discovery that by indexing the knife in the direction of rotation of the core, at least one additional fresh cutting edge can be presented to the work than would be the case if the knife were rotated in the direction opposite to the direction of rotation of the core to be cut.

Abstract: A core drive for internal drive core cutters having a non-rotating pull rod and a rotating drive plate. The core drive has a rotating element assembly that releasably couples to the drive plate and a non-rotating element assembly that is secured to the pull rod with a quick release securement. The drive is mated with a pusher so that the drive and pusher kit can be interchangeable with kits of other diameters to enable the quick changing of a mandrel to cut a core of a different diameter.

Abstract: A manifolded multiple wand spray apparatus with internal cleaning brushes and a flush valve that is activated when the rods carrying the cleaning brushes are rotated is disclosed. Valves that redirect the flow of water away from the manifold for a brief period during which spray orifice cleaning can be accomplished and an air intake valve that will admit air into the manifold to speed the flushing and create a negative pressure in the spray wands so as to draw obstructing materials into the spray wand during flushing is also disclosed.

Abstract: Flowable loose packing dunnage is formed from paperboard into three dimensional particles of various shapes. Also, an apparatus for forming the dunnage employs two vertically aligned arrays of toothed, untoothed and/or cutting wheels through the nip of which paperboard segments pass and by which they are shaped into dunnage particles. Further, in a method of forming the dunnage particles, strips of paperboard are cut into segments which are formed into three dimensional shapes. A method of protecting a packed object surrounds it with the flowable loose packing dunnage made of paperboard in accordance with the present invention.
