Feed composition cycling equipment

Figure 2. Detail of the feed composition cycling and flow control equipment.

An analogue display system Incorporating A and B scans was chosen, the B scan drawn on an oscilloscope was scaled using positional feed back from the manipulators and Information from the A scans on the flaw detector. A composite B scan could be drawn for each scan sequence (Fig 4) and erased after each complete cycle. Using video equipment the A and B scans were then mixed on to a monitor with digital Information Inlaid through a number Inlay unit. This Information was then recorded on video tape.
