Abstract: A head stack assembly comb (154) for maintaining the heads (44) of a head stack assembly (26) in spaced relation is disclosed. The head stack assembly comb (154) includes a comb body (158) and a latch (218). The comb body (158) engages an upper surface of an uppermost actuator arm (30a) in the head stack assembly (26). The latch (218) engages a lower surface of this same actuator arm (30a). When installing the comb (154), the comb (154) is pivoted relative to the head stack assembly (26). This brings the latch (218) into engagement with the noted actuator arm (30a) and causes the latch (218) to pivot in a first direction against a spring (214), and then in the opposite direction by the action of the spring (214) on the latch (218) to engage the latch (218) with the lower surface of the noted actuator arm (30a).

Abstract: A material delivery system is disclosed which is particularly useful for filtered environments, such as clean rooms, minienvironments, or the like. One aspect of this particular material delivery system is that movement of an elevator is automatically controlled (i.e., no operator input), and more preferably is accomplished by monitoring for the presence of containers at multiple vertical positions. Another aspect of this particular material delivery system is that its elevator may be installed on and removed from a main housing of the material delivery system without requiring any tools. Yet another aspect of this particular material delivery system is that containers need not be unloaded from the material delivery system prior to removing its elevator, such as for replacement/maintenance purposes.
