Figure 10.  Cut away diagram showing the concave-upwards stacking arrangement of the discs in the manifold chamber of the Intervalometer. This stacking arrangement reduces cohesion between the discs and facilitates their release from the manifold and subsequent capture by the rotor. Scale refers to the discs.
