Abstract
Abstract A liquid in a transparent container has a relatively small quantity of pearl essence crystalline powder pigment mixed therewith. When quiescent, the mixture appears substantially opaque and lacking a mist pattern. When agitated, as by stirring by a motor-driven bar or propeller or the like, the mixture while remaining substantially opaque takes on a constantly changing mist pattern containing, for example, randomly moving veins of gold, streaks, lines, and/or areas, all more or less darkened, which constantly alter their shape, texture, direction and dimensions. It may be said to simulate marble wherein the veins are in constant change and flux. When a lamp is lit within or without the enclosure of the container, the mixture is made to appear translucent.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
In combination, a substantially transparent container containing a normally quiescent and substantially opaque mixture composed of a liquid vehicle and a pearlescent pigment, and means for effecting in said mixture a constantly changing visual pattern of mist and pearlescent veins, said means comprising means for stirring said mixture, a support of nonmagnetizeable material upon which said container rests, said last-named means comprising a motor mounted under said support and having a vertical drive shaft directed toward the bottom of said container, said shaft having a magnet rigid on the upper end thereof and spaced from but close to the underside of said support, the container having a magnetizeable member resting loosely on the bottom thereof and positioned vertically above said magnet whereby upon energization of the motor said magnetizeable member moves in synchronism with said magnet on said shaft.
Claim 2
Dependent Claim
139 words
In combination, a substantially transparent container containing a normally quiescent and substantially opaque mixture composed of a liquid vehicle and a pearlescent pigment, and means for effecting in said mixture a constantly changing visual pattern of mist and pearlescent veins, said means comprising means for stirring said mixture, a support of nonmagnetizeable material upon which said container rests, said last-named means comprising a motor mounted under said support and having a vertical drive shaft directed toward the bottom of said container, said shaft having a magnet rigid on the upper end thereof and spaced from but close to the underside of said support, the container having a magnetizeable member resting loosely on the bottom thereof and positioned vertically above said magnet whereby upon energization of the motor said magnetizeable member moves in synchronism with said magnet on said shaft.
Claim 3
Dependent Claim
37 words
A combination according to claim 1, said magnet on said shaft and said magnetizeable member having the centers thereof positioned in vertical alignment with each other and substantially with the center of said bottom of the container.
Claim 4
Dependent Claim
31 words
A combination according to claim 4, said magnet having the form of a bar magnet, said magnetizeable member comprising a bar magnet, both of said magnets having substantially the same length.
Claim 5
Dependent Claim
19 words
A combination according to claim 2, said magnetizeable member having a coating of plastic material covering the surface thereof.
Claim 6
Dependent Claim
32 words
A combination according to claim 1, said container having an inwardly directed tubular passage closed at its inner end extending into the body thereof, and an electric lamp mounted in said passage.
Claim 7
Dependent Claim
16 words
A combination according to claim 1, said magnetizeable member having a coating of plastic material thereon.
Claim 8
Dependent Claim
162 words
In combination, a substantially transparent container containing a normally quiescent and substantially opaque mixture composed of a liquid vehicle and a pearlescenT pigment, and means for effecting in said mixture a constantly changing visual pattern of mist and pearlescent veins, said means comprising means for stirring said mixture, a support of nonmagnetizeable material upon which said container rests, said last-named means comprising a motor mounted under said support and having a vertical drive shaft directed substantially toward the center of the bottom of the container, said shaft having a disc of nonmagnetizeable material mounted on the upper end thereof and coaxial therewith, said disc being positioned closely adjacent the underside of said support and having a magnet mounted eccentrically thereon, the container having a magnetizeable member resting loosely on the bottom thereof and positioned at the same degree of eccentricity with respect to the center of said bottom of the container as the eccentricity of said magnet with respect to said shaft.
Claim 9
Dependent Claim
162 words
In combination, a substantially transparent container containing a normally quiescent and substantially opaque mixture composed of a liquid vehicle and a pearlescenT pigment, and means for effecting in said mixture a constantly changing visual pattern of mist and pearlescent veins, said means comprising means for stirring said mixture, a support of nonmagnetizeable material upon which said container rests, said last-named means comprising a motor mounted under said support and having a vertical drive shaft directed substantially toward the center of the bottom of the container, said shaft having a disc of nonmagnetizeable material mounted on the upper end thereof and coaxial therewith, said disc being positioned closely adjacent the underside of said support and having a magnet mounted eccentrically thereon, the container having a magnetizeable member resting loosely on the bottom thereof and positioned at the same degree of eccentricity with respect to the center of said bottom of the container as the eccentricity of said magnet with respect to said shaft.
Claim 10
Dependent Claim
31 words
A combination according to claim 7, said magnet having the form of a bar magnet, said magnetizeable member comprising a bar magnet, both of said magnets having substantially the same length.
Claim 11
Dependent Claim

A combination according to claim 7, said magnetizeable member having a coating of plastic material thereon.
Claim 12
Dependent Claim
19 words
A combination according to claim 7, said magnetizeable member having a coating of plastic material covering the surface thereof.
Claim 13
Dependent Claim
32 words
A combination according to claim 7, said container having an inwardly directed tubular passage closed at its inner end extending into the body thereof, and an electric lamp mounted in said passage.
