Certain exemplary embodiments can provide a system comprising a tub, a cover, a wick, and a diffuser cap. The tub defines a cavity. The tub is constructed to hold a liquid in the cavity. The tub comprises a top ring. The cover is constructed to be coupled to the top ring of the tub. The cover defines an aperture. The wick is constructed to convey a liquid via diffusion. The diffuser cap comprises a central stem. The central stem is constructed to engage with the wick. The diffuser cap is constructed to vent vapor conveyed to the diffuser cap via the wick.

The invention is a vapourising device (10) for vapourising a volatile liquid for supply to an environment. The device has a housing 100 having an inlet (109) for receiving inlet air which is warmed by inlet heater (111) before being supplied to cartridge assembly (200). Cartridge assembly (200) has a reservoir (204) for containing the liquid to be vapourised and at least one wick (206), one end of which is located in the reservoir to receive and transport the liquid to the other, exposed end of the wick where the liquid evaporates and mixes with the supplied stream of heated inlet air. The wick may be heated by a wick heater (211). The device also includes an outlet duct section (217) between the wick (206) and the outlet (221) which is conical in shape and is configured to accelerate the flow of the mixture of inlet air and vapourised liquid away from the wick towards the outlet (221). The invention provides increased control of the vapourisation process and helps to reduce condensation of the volatile liquid back onto the apparatus or onto surrounding surfaces.

A rotary separation devise deploys a drum with mesh like opening on the cylindrical surfaces and a removable cover or cap for filling in an upright position and removal of product or spent matter in an inverted position. When the drum is loaded with material, and the cover closed, it is rotatable to a horizontal position, and disposed in an outer container. The drum is rotated in the horizontal position to initiate the separation process. The outer container may be formed by the mating engagement at a common rim of an upper and lower vessel that form the sealed container.

An apparatus includes a portable housing with a cavity, a heater disposed within the cavity of the housing, a temperature buffering device coupled to the heater and disposed within the cavity of the housing, a non-biological skin substitute substrate coupled to the temperature buffering device and disposed within the cavity of the housing, and a carbon dioxide delivery device coupled to the housing. The non-biological skin substrate simulates a surface property of human skin.
