Abstract: In a method of cleaning a rotary mixing device having a mixer portion and a driving shaft, a shield is located over at least the mixer portion. The mixing device is rotated, expelling material clinging to or trapped by the mixing portion, such as paint, from the mixer portion of the mixing device. This material is blocked or caught by the shield. In one embodiment, the shield is cylindrical in shape and has a base with an opening through which the shaft of the mixing device may extend, and an open second end leading to an interior area for containing the mixer portion of the mixing device.

Abstract: A patch system for patching a hole in a wall surface. The system comprises an original plate member, a surface sheet, and adhesive material. At least one scored line is formed on the original plate member. The original plate member may be broken along the at least one scored line to obtain a plurality of sub-plate members. The sub-plate members are smaller than the original plate member. The surface sheet defines first and second surfaces. The adhesive material secures the original plate member or one of the sub-plate members to the first surface of the surface sheet. The adhesive material further secures at least a portion of the first surface of the surface sheet to the wall surface such that the rigid plate and the surface sheet are held in a desired position relative to the hole.
