A circular waved
Ceramic saddles retaining raschig ring is formed from two turns of a flat elongate wire strip and which follow a continuous sinusoidal wave path that includes a series of waves equidistantly spaced about the ring wavepath, each wave
Silicon carbide ring having a shoulder portion which bears against generally parallel surfaces of the working elements positioned on a shaft or in a cylinder bore. The ring fits in a
catalyst carrier rectangular groove formed either on a shaft or in a cylinder bore, the width of the groove being slightly greater than the distance between successive wave crests and troughs.
