Abstract

An oscillating wave cell is disclosed. The oscillating wave cell comprises a substantially transparent, fluid vessel having a generally upper surface, a generally lower surface and transparent end caps. The wave cell contains first and second immiscible fluids of different colors, such as primarily a light mineral spirits and water. An air trap is provided which extends downwardly from the lower surface of the vessel. The air trap includes a partition defining a first trap chamber and a second trap chamber. The air trap further includes a plurality of passages extending between the vessel and the first trap chamber for permitting fluid flow therebetween. The partition extends downwardly from the lower vessel surface and includes a slot disposed away from the lower surface for permitting fluid flow between the first trap chamber and the second trap chamber. A base having an upwardly extending rocker mechanism including a cradle concealingly receives the air trap and supports the vessel.

Claims

1. A wave cell adapted for mounting on an oscillating base, the wave cell comprising:

a substantially transparent fluid vessel having, opposing ends, a generally upper surface and a generally lower surface said lower surface adapted for engaging said base, and said upper surface disposed opposite said lower surface; and

an air trap disposed on said lower surface.

2. The wave cell of claim 1 wherein said chamber is cylindrical.

3. The wave cell of claim 1 wherein said chamber has substantially transparent end caps.

4. The wave cell of claim 1 wherein said vessel contains first and second immiscible fluids.

5. The wave cell of claim 4 wherein said first and second immiscible fluids are of different colors.

6. The wave cell of claim 4 wherein said first immiscible fluid is principally a light mineral spirits and said second immiscible fluid is principally water.

7. A wave cell adapted for mounting on an oscillating base, the wave cell comprising:

a substantially transparent fluid vessel having a generally upper surface and a generally lower surface; and

an air trap disposed on said lower surface, wherein said air trap includes a partition defining a first trap chamber and a second trap chamber, said wave cell including means for permitting fluid flow between said vessel and said first trap chamber, and means disposed away from said lower surface for permitting fluid flow between said first trap chamber and said second trap chamber.

8. The wave cell of claim 7 wherein said means for permitting fluid flow between said vessel and said first trap chamber comprises a plurality of passages.

9. The wave cell of claim 7 wherein:

said partition extends downwardly from said lower vessel surface; and

said means disposed away from said lower surface for permitting fluid flow between said first trap chamber and said second trap chamber comprises a slot in said partition disposed away from said lower surface.

10. An oscillating wave cell comprising:

a base;

a wave cell including a substantially transparent fluid vessel having opposing ends, a generally upper surface and a generally lower surface, said lower surface adapted for engaging said base, and said upper surface disposed opposite said lower surface and an air trap extending downwardly from said lower surface;

wherein said base has an upwardly extending rocker mechanism including a cradle for receiving said air trap.

11. The oscillating wave cell of claim 10 wherein said air trap is concealed in said base.

12. The oscillating wave cell of claim 10 wherein said vessel is cylindrical.

13. The oscillating wave cell of claim 10 wherein said chamber has substantially transparent end caps.

14. The wave cell of claim 10 wherein said vessel contains first and second immiscible fluids.

15. The wave cell of claim 14 wherein said first and second immiscible fluids are of different colors.

16. The wave cell of claim 14 wherein said first immiscible fluid is principally a light mineral spirits and said second immiscible fluid is principally water.

17. An oscillating wave cell comprising:

a wave cell including a substantially transparent fluid vessel having a generally upper surface and a generally lower surface and an air trap extending downwardly from said lower surface;

a base having an upwardly extending rocker mechanism including a cradle for receiving said air trap, wherein said air trap includes a partition defining a first trap chamber and a second trap chamber, said wave cell including means for permitting fluid flow between said vessel and said first trap chamber, and means disposed away from said lower surface for permitting fluid flow between said first trap chamber and said second trap chamber.

18. The wave cell of claim 17 wherein said means for permitting fluid flow between said vessel and said first trap chamber comprises a plurality of passages.

19. The wave cell of claim 17 wherein:

said partition extends downwardly from said lower vessel surface; and

said means disposed away from said lower surface for permitting fluid flow between said first trap chamber and said second trap chamber comprises a slot in said partition disposed away from said lower surface.

20. An oscillating wave cell comprising:

a base;

a substantially transparent fluid vessel having opposing ends, a generally upper surface and a generally lower surface, said lower surface adapted for engaging said base, and said upper surface disposed opposite said lower surface, said wave cell containing first and second immiscible fluids;

an air trap extending downwardly from said lower surface, said air trap including a partition defining a first trap chamber and a second trap chamber, said air trap further including a plurality of passages extending between said vessel and said first trap chamber for permitting fluid flow therebetween, and said partition extends downwardly from said lower vessel surface and includes a slot disposed away from said lower surface for permitting fluid flow between said first trap chamber and said second trap chamber; and

wherein said base has an upwardly extending rocker mechanism including a cradle for concealing receiving said air trap.

21. The oscillating wave cell of claim 20 wherein said vessel is cylindrical having substantially transparent end caps.

22. The wave cell of claim 20 wherein said first and second immiscible fluids are of different colors.
