Abstract: A bowling ball abrader and polisher utilizes cooperative rotational inter-engagement between a cup-shaped abrading an polishing tool and a non-motorized rotating ball holder assembly to obtain even, concentric abrasion patterns on a bowling ball surface. Upon placement of a bowling ball in a ball cradling surface formed in the rotating ball holder, application of the rotating abrading and polishing tool on the surface of the bowling ball causes a corresponding rotation of the bowling ball using the non-motorized rotating ball holder, which enables the outer surface of the bowling ball to be more uniformly abraded and polished.

Abstract: A processing apparatus for comestibles such as nuts and syrup comprising a kettle having an opening at one end thereof for access for insertion and removal of the comestibles. The kettle has a generally concave shape and is rotatable about an axis with respect to a supporting base. The kettle has a generally concave surface symmetric with respect the rotation axis. A mixing device is provided and is mounted stationary with respect to the rotating kettle and comprises an elongate substantially rigid bar which has a concave shape and is spaced from the rotating concave surface of the kettle. The bar contacts the comestibles during rotation of the kettle and continuously turns the comestibles to provide substantially uniform mixing thereof.
