A system and method for extracting essential oils is provided. One embodiment comprises an extractor assembly with an extractor cover, an extractor container, and an extractor assembly base, wherein the extractor container is secured between the extractor cover and the extractor assembly base during an extraction process; a bowl cover assembly with a collection bowl, and a bowl cover assembly base, wherein the collection bowl is secured between the extractor assembly base and the bowl cover assembly base during the extraction process; and a canister compression holder assembly, wherein a cannister containing a solvent is secured within the canister compression holder assembly during the extraction process. A solvent that is released from the cannister passes into the extractor container that contains matter that is to have essential oils extracted therefrom. The extracted oils exits the extractor assembly base into the collection bowl that collects the solvent with the essential oils.

Disclosed are methods, systems, canisters, and other implementations, including a method of filling a filter canister with a particulate filter material to a desired packing density comprises providing a canister having a fill opening through which the particulate filter material is introduced into the canister, introducing the particulate filter material through the fill opening, and subjecting the canister to centrifugal forces for a time until the desired packing density is reached is provided.

The present invention relates to a novel process for crystallizing high purity lutein and zeaxanthin esters from marigold oleoresin. In another aspect, the present invention relates to the removal of soft and hard waxes by adsorption on diatomaceous earth or other filter aid using acetone or other organic solvent. Another aspect of the present invention relates to achieving high-purity lutein and zeaxanthin esters, including purity levels that are about 90 to 95%.

The present disclosure provides a flow-through aerosol capture device that includes a chamber defining an airflow path, and at least one heat-stable aerogel filter, for example a heat-stable polymer aerogel filter, disposed in the airflow path for capturing aerosol particles when an aerosol-containing gas passes through the filter. The flow-through aerosol capture device may be a needle-trap device or a thermal desorption liner with a heat-stable aerogel filter in the lumen of the needle or the liner. The disclosure also provides heat-stable polymer aerogels and methods of making such aerogels.

A headrest assembly for supporting a head or face of a user of a treatment device includes a headrest and a filter assembly. The headrest is configured to support the head or face of the user. The filter assembly is coupled to the headrest. The filter assembly includes a filter connector that is selectively coupled to the headrest, and a filter body that extends in a generally downward direction away from the filter connector. The filter body can extend in a generally downward direction away from an inner edge or an outer edge of the filter connector. The filter body includes sides and a base that cooperate to define at least a portion of a filtering cavity that is configured to be positioned substantially directly below the head or face of the user when the head or face of the user is supported by the headrest.

Disclosed is a storage-type modular data center. The storage-type modular data center includes a box, a dust removing module, an evaporative cooling module, and an air supply module. The box is provided with an air inlet and an air outlet. A server is disposed between the air inlet and the air outlet. The dust removing module is disposed between the server and the air inlet. The evaporative cooling module is disposed between the server and the air inlet, and includes an evaporative media and a water sprinkling tray module. One end of the evaporative media is immersed in liquid contained in the water sprinkling tray module. The air supply module is operative to drive air to flow between the air inlet and the air outlet.
