Abstract: A brush for removing cremated remains from a crematory oven is entirely formed of metal to resist the high temperatures of the oven and has two linear brush assemblies fixed to a top frame. A steel handle extends rearwardly from the frame for grasping by a brush operator. One of the linear brush assemblies has smaller diameter crimped stainless steel bristles and is positioned at the front of the brush, the other of the linear brush assemblies has larger diameter crimped stainless steel bristles and is fixed to the top frame rearward of the front brush assembly. Side brush assemblies extend sidewardly and upwardly of the other two. In operation the brush is inserted at the front of the oven and drawn rearwardly after the cremation such that the rear bristles encounter and withdraw the larger elements of the remains, and the front bristles encounter and withdraw the smaller elements.

Abstract: During polishing of a substrate a sequence of measured values is received from an in-situ motor torque monitoring system. Positions on the substrate of the region of lower coefficient of friction are calculated for at least two measured values from the sequence of measured values. A first measured value from the sequence of measured values at which the region of different coefficient of friction is at a first position in a first zone on the substrate is compared to a second measured value from the sequence of measured values at which the region of different coefficient of friction is at a second position in a different second zone on the substrate or is not below the substrate. Based on the comparison, which of the first zone or the second zone the overlying layer is clearing first to expose the underlying layer can be determined.
