Abstract
Abstract A vessel filled with two liquids of different specific gravities is provided with a centrifugal impeller for creating a vortex from the liquid of lesser specific gravity to simulate a cyclone. Ornaments may be disposed within the vessel for generating additional visual effects during the formation of the vortex.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A cyclonic liquid ornament comprising: a) a transparent vessel; b) two liquids of different specific gravities contained within the vessel; c) a centrifugal impeller for creating a vortex from the liquid of lesser specific gravity to simulate a cyclone formation within the vessel; and d) a light-reflecting ball within the vessel and means for directing light onto the ball.
Claim 2
Dependent Claim
59 words
A cyclonic liquid ornament comprising: a) a transparent vessel; b) two liquids of different specific gravities contained within the vessel; c) a centrifugal impeller for creating a vortex from the liquid of lesser specific gravity to simulate a cyclone formation within the vessel; and d) a light-reflecting ball within the vessel and means for directing light onto the ball.
Claim 3
Dependent Claim
25 words
The ornament of claim 1 further including: a) a base supporting the vessel; b) drive means contained within the base for rotating the centrifugal impeller.
Claim 4
Dependent Claim
15 words
The liquid ornament of claim 1 wherein the liquid of lesser specific gravity is dyed.
Claim 5
Dependent Claim
16 words
The liquid ornament of claim 1 further including at least one floating ornament within the vessel.
Claim 6
Dependent Claim
146 words
A cyclonic liquid ornament comprising: a) a transparent vessel; b) two liquids of different specific gravities contained within the vessel; c) a centrifugal impeller for creating a vortex from the liquid of lesser specific gravity to simulate a cyclone formation within the vessel; d) a base supporting the vessel; e) drive means contained within the base for rotating the centrifugal impeller; f) a partition board disposed within the vessel and positioned above the centrifugal impeller, the partition board including a suction intake eccentrically offset from a central axis of the vessel and a plurality of peripheral discharge outlets; g) the impeller being positioned below the suction intake and including a first half of a magnetic drive assembly; h) the drive means including a second half of a magnetic drive assembly and a motor for rotating same; and j) means for varying the speed of the motor.
Claim 7
Dependent Claim
