Apparatus and method for providing a suspended agent

摘要

Apparatus and methods for maintaining the suspension of an agent suspended in a suspending medium in which a container holding the agent is revolved about an axis to create and maintain the suspension and the agent is selectively provided from the container. The agent may be selectively provided from the container while the container is simultaneously or intermittently revolved in a planetary orbit about an axis of rotation generally parallel to an axis of the container for maintaining the suspension. Alternatively, the container may be rotated about its longitudinal axis by a source of rotation to create and maintain the suspension while the agent is provided from the container due to a force imparted by the source of rotation.
