Figure 26. Top plate holder



The bottom disk was hung by securing four support rods, Figure 27, to the disk at

the countersink locations. The top circular plate rest on a shoulder machined onto the

support rod. The light plates on the bottom were fed fiber optics via a transport tube

that was dropped down directly on top of them. The support rods were screwed to the

blind flange at the top of the reactor to secure and square them. The transport tubes

pass through the blind flange and are supported by the stoppers located at the top of

the tube.

The plates are held using a slot and bolt mechanism shown in. This design allows

for easy assembly and removal for cleaning and maintenance purposes. Figure 28
