A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.

A steam vaporizer assembly includes an internal steam generator having a vessel configured to hold water, a vaporizer unit having a heating element configured to heat the water to generate saturated steam; and a controller configured to: cause the heating element to heat the water to a stand-by temperature; and while maintaining a water level of the water in the vessel between two control points: maintain the water in the vessel at the stand-by temperature until steam generation is required, and when steam generation is required, heating the water in the vessel from the stand-by temperature to a temperature at or above a vaporization temperature of the water using a heating element, to generate the steam.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side. The methods and apparatus includes plurality of heating elements that may be individually and/or selectively addressable by at least three electrode leads.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.

A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

The present invention relates to a steam system for a steam cooking appliance. The steam system includes a steam generator and a precipitator. The precipitator is arranged above the steam generator. The steam generator comprises two vertical heating pipe sections. Upper ends of the heating pipe sections are connected to a bottom side of the precipitator. Lower ends of the heating pipe sections are connected by a transverse pipe section. At least the heating pipe sections are at least partially enclosed by one of more heating elements. An inlet pipe is connected to the transverse pipe section at one end and connected or connectable to a water reservoir or water pump at another end. A return pipe is interconnected between the bottom side of the precipitator and the transverse pipe section. Further, the present invention relates to a corresponding steam cooking appliance.

A steam generator and a cooking device including the same, according to an embodiment of the present invention may include a water supply pipe into which steam water is introduced, a heating chamber having a chamber body and a chamber cover, and a steam heater configured to provide heat, wherein the steam heater is provided to be embedded in the chamber body and the chamber body includes a plurality of partition walls protruding in one direction along an inner peripheral surface to form a Z-shaped steam flow path through which supply water introduced into the chamber body and steam generated by heating the supply water flow. Therefore, the heat transfer, which had been concentrated only in a predetermined region, may be dispersed by the flow path formed in the chamber body, thereby stably generating the steam even in repetitive steam generation operation.
