Abstract: An animal interaction device with a base, a housing, and a feeding mechanism having a rotatable platform mounted on the top surface of the base to rotate about an axis of rotation. There is a low profile drive cavity between the platform and the base and a food tray disposed on a top surface of the platform. A drive mechanism is located within the drive cavity and includes a drive mechanism with a curved rack gear engaged with the rotatable platform. There is a horizontally disposed worm drive mounted in communication with the curved rack gear to enable rotation of the rotatable platform about the axis of rotation. As the platform is rotated, the food tray moves from a first position where the tray is concealed under the housing to a second position outside of the housing, thereby allowing access to the food tray by an animal.

Abstract: An improved, automatic slide specimen staining apparatus. The apparatus includes a covered housing containing a plurality of baths, input and withdrawal drawers and a three direction slide racks transport mechanism. The transport mechanism is controlled in its movement of slide racks, from bath to bath between an initial position to a final position; the transport mechanism is under the control of a microprocessor control system programmed with a series of staining schedules that are operator selective for a given slide rack input from the initial position, the microprocessor control system interactively determining individual slide rack movement timing through selected baths.
