In the second patent, it states: "With the disc or discs in place [the CICs] a capture ring of geometrical dimension to fit within the central opening and cover the edge of the other side of the disc is placed in central opening on the other side of the disc or discs and secured to the annular ring by sonic welding."

I have posted this picture previously with the supposition that a ring was used to secure the CIC's in-place. But I thought that heat, or some sort of glue, was used to secure the ring in-place. Your patent reference shows that "sonic welding" was the agent used to secure the ring. The image here reflects a failed welding, at least for 40 or 50 percent of the ring's circumference, on this Colorado Belle, $5 chip.

Thanks Roy!!
