Abstract: A key duplicating machine having a key clamping assembly for supporting a key blank and a customer key to be duplicated, a key cutter assembly having a cutter wheel for cutting a pattern on the supported key blank and a follower for tracing a tooth patter on the supported customer key, a housing having a front wall, a top wall and a chip collection drawer lcoated below the front and top walls, the key clamping assembly being mounted on the front wall and the key cutter assembly being mounted on the top wall such that no obstructions exist between the key cutter assembly and the chip collection drawer located below the top wall, so that chips formed from a key cutting operation by the key cutter assembly fall unimpeded to the chip collection drawer, and surfaces which may collect the chips are minimized.

Abstract: Method and apparatus for coating catalytic converter substrates with an exact amount of a precious metal. In the course of operation of the apparatus, a hollow substrate to be treated having opposed open ends is transferred from a starting location such that one end is lowered into a dip pan into which has been introduced a predetermined amount of slurry material containing the precious metal. With the one end immersed in the slurry, a vacuum placed on the other end of the substrate draws up the entire charge of slurry from the dip pan to coat the lower portion of the substrate. Thereafter, the substrate is raised from the dip pan. The vacuum continues to operate to cause the coating to be evenly distributed on all the interior surfaces of the substrate. Then the substrate is rotated and again lowered so that the other end is immersed in another predetermined charge of the slurry and the process is repeated. Thereupon, the substrate is again raised from the dip pan.
