17. The imitation candle of claim 16, wherein:
a) the fragrance emitter further comprises a fragrance wick coupled to the fragrance reservoir for disseminating a fragrance from the fragrance reservoir b) the fragrance wick extends from the fragrance reservoir and into the fragrance aperture.
18. The imitation candle of claim 8, further comprising a power source powering the electric light source and the fragrance emitter, the power source housed within the lower cavity.
19. The imitation candle of claim 1, wherein the electric light source comprises a light emitting diode.
20. An imitation candle comprising:
a) an imitation candle body defining an upper cavity generally open to the outside environment, and a lower cavity;
b) an electric light source for producing an imitation flame, the electric light source positioned in the upper cavity; and
c) a fragrance emitter for producing a fragrance, the fragrance emitter comprising: (i) a fragrance reservoir for storing a fragrant fluid, the fragrance reservoir positioned in the lower cavity, (ii) a fragrance wick coupled to the fragrance reservoir for diffusing a fragrance from the fragrant fluid, and (iii) an electric heat source for heating the fragrant fluid; and
d) a power source positioned in the lower cavity and powering the electric light source and the electric heat source.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus providing a reaction chamber for an oxygen-sensitive or water-sensitive reactant in a cavitation induced liquid reaction medium, the apparatus comprising:
a reaction chamber having a liquid space for a liquid reaction medium and a gas space overlying the liquid space when it contains liquid reaction medium, the reaction chamber excluding admission of ambient air;
means for producing cavitation in the liquid reaction medium;
at least one reactant inlet to at least one of the gas space or the liquid space for adding a reactant to the reaction chamber;
an inert gas inlet conduit with a sparger for injecting a flowing stream comprising inert gas into the liquid space of the reaction chamber;
a venting outlet for removal of a stream comprising inert gas from the gas space in the reaction chamber;
a recirculation conduit for re-circulating a stream of the inert gas from the venting outlet to the inert gas inlet conduit;
a heat exchanger in the recirculation conduit for condensing reaction medium entrained in the removed stream of inert gas for return to the reaction chamber;
and a reaction product outlet from the reaction chamber.
2. An apparatus as recited in claim 1 further comprising a gas pump in the recirculation conduit.
3. An apparatus as recited in claim 2 further comprising at least one of a needle valve, a pressure gauge, or a gas flow meter in the recirculation conduit to control the stream of the inert gas.
4. An apparatus as recited in claim 1 wherein the means for producing cavitation comprises an ultrasonic generator.
5. An apparatus as recited in claim 1 wherein the means for producing cavitation comprises a cavitation inducer acting on a wall of the reaction chamber.
6. An apparatus as recited in claim 1 wherein the means for producing cavitation comprises cavitation inducing plates immersed in the liquid reaction medium.
7. An apparatus as recited in claim 1 further comprising a hydrocarbon trap in the recirculation conduit.
