The table cores (micro pills, small pills or plain tablets) to be film coated make continuous complicated orbital motion within a closed rotating drum under the action of a streamline guide plate. Controlled by computer and according to the optimum technological parameters, they are automatically sprayed with film coating medium while hot air under a negative pressure is led in from one side of an air distributing pipe at the center of the drum, clean hot air penetrates through the tablet core layers and is discharged after being collected to the other side of the air distributing pipe by a pore duckbill-shapedair paddle embedded in the tablet core layers, so that the film coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thereby forming a layer of solid, compact, neat and smooth surface film.

Based on the 1T15M-2 reversible sleeve air spring made by Firestone Corp., an air spring with auxiliary chamber was built. The character of the air spring in vertical direction was described as a linear spring damper element. Using the method of free vibration with damping, the changing rules of the stiffness and damping under different pressure in the air spring with the change of throttle orifice diameter have been studied experimentally.
