A chair-desk frame has a forward portion and a rearward portion. An assembly for honing a workpiece, the assembly having a plurality of hone tools each having abrasive surfaces configured to remove a portion of exterior non-uniform surfaces of a workpiece pushed through the hone tool, wherein the hone tool is configured to surround the entire periphery of the workpiece being passed therethrough. The new material is a bonded matrix of the fibers and the white pigment compound having particles of the fine particulate material, eg TiO2, dispersed and bonded within the matrix. A sinusoidal shaper is coupled to the output of the shift register to provide a signal modulated in frequency by the input signal. This way, the animal learns to associate movement in the correct direction andor proper orientation as gradually increasing positive reinforcement andor reducing negative reinforcement. The apparatus is intended to be installed on an automotive hoist at a height approximately the same as that of a tire of a vehicle disposed on the hoist.
