Abstract:
1. An apparatus for shaking a container, comprising: a base plate, wherein said base plate is a cantilevered base plate; a motor mount supported by said base plate; a motor coupled to said motor mount a shaft, wherein said motor is configured to rotate said shaft; a wheel coupled to said shaft, wherein said wheel is configured to eccentrically rotate about said shaft, and wherein said wheel is a cam; a bearing, wherein said wheel is configured to rotate within said bearing; a container base coupled to said bearing such that said container base is configured to move in substantial accordance with said eccentric rotation of said wheel while dynamically tilting in a vertical direction, resulting in a vertical movement that is not de minimis; and at least one container coupled to said container base, and wherein the container tilts in substantial accordance with the translation of said container base; wherein said base plate is configured to flex according to said translation of said container base, wherein said base plate is made of a material that allows said base plate to flex generally downward as said container base moves away from a fixed portion of said base plate and wherein said base plate is made of a material that allows said based plate to flex generally upward as said container base moves toward a fixed portion of said base plate.
