An assembly for a vapor provision device includes a reservoir for storing source liquid; a liquid conduit for delivering the source liquid from the reservoir to a vapor generator for vaporizing the source liquid; and a liquid capture element in liquid transfer contact with at least a portion of the liquid conduit between the vapor generator and a part of the liquid conduit that receives liquid from the reservoir, and including an absorbent structure providing a higher capillary force than a capillary force of the reservoir.

Disclosed herein are methods and systems to vaporize extract, plant material containing organic material and the like utilizing convection heating via one or more manifolds each in fluid communication with a section of chamber containing organic material. The manifolds may be valved and may contain temperature sensors.

A light fixture is provided with a heating element. The heating element can be a resistive heating element, such as a Nichrome wire, and resides in grooves of a cover (e.g., a glass globe) of the light fixture. Thus, the heating element acts to directly heat the cover of the light fixture to prevent, decrease, or otherwise correct frosting, freezing, and other elemental effects on the cover when it is exposed to the environment. The heating element is capable of raising the temperature of the cover at least 15° C. from an initial temperature of −20° C. in 30 minutes. A heat sensing element may provide feedback regarding the temperature of the cover for controlling power supplied to the heating element.

An electric heating mat may include an outer sleeve having an interior, and an access end with an opening to the interior. The access end may be folded upon itself into a closed condition, and unfolded into an opened condition. When the access end is closed, the interior of the outer sleeve may provide a sealed enclosure. The sealed enclosure may accommodate and protect internal components, such as heating elements, a power source, and associated controls. The heating elements, associated wiring, and an insulation layer may be provided in an inner sleeve, which may be insertable into the outer sleeve as a unit. When the access end is opened, the opening provides access to the internal components. Such access allows the power source to be turned on to supply power to the heating elements.

A transparent pane is described, having an electrical heating layer extending at least over part of the pane surface and divided into a main heating region and an additional heating region electrically insulated therefrom. The transparent pane has connection means, which can be electrically connected to a voltage source and which has at least a first collecting conductor and a second collecting conductor. The collecting conductors are each electrically connected to the heating layer in the main heating region in direct contact such that upon application of a supply voltage, a heating current flows across a heating field formed by the heating layer. The transparent pane has at least one electrical line heating element, which is arranged, at least in sections, in the additional heating region of the heating layer.

A snow melting apparatus for melting snow on sidewalks, driveways, and other walkways is provided. The snow melting apparatus comprises a plurality of individual heating cables with the heat cables woven together to form a mesh-like covering mat and the covering mat having a top surface and a bottom surface. An outer perimeter border surrounds the covering mat. A snowfall sensor mechanism is mounted to the covering mat with the snowfall sensor mechanism detecting precipitation and automatically activating the heating cables. The top surface of the covering mat is presented for a person to walk and or stand while the bottom surface of the covering mat is capable of being positioned against the sidewalk, driveway, or other walkway. Upon activation of the heating cables, the temperature of the heating cables increases thereby heating the entire covering mat.

An aerosol delivery device having a detachable power source is provided. A control body may be coupleable with a cartridge to form an aerosol delivery device. The cartridge may contain an aerosol precursor composition and be equipped with a heating element configured to activate and vaporize components of the aerosol precursor composition. The control body may comprise a housing and a power source detachably coupled to an outer surface of the housing. A control component may be contained within the housing and configured to operate in an active mode in which the control body is coupled with the cartridge. The control component in the active mode may be configured to direct power from the power source to the heating element to activate and vaporize components of the aerosol precursor composition.

A heat exchanger for fluids includes an elongated conduit. At least two spaced fluid passageways are defined in the conduit and extend longitudinally through the conduit from a first end thereof to a second end thereof. A heat transfer element thermally contacts a surface of the conduit to transfer heat to or from a fluid flowing through the at least two spaced passageways. The conduit can be unitary and of one piece. In one embodiment, the conduit can be a single crystal.

An exhaust gas heater system for an exhaust system of an internal combustion engine includes a housing and a heating element. The housing includes an outer peripheral wall disposed about a central axis and defining an interior hollow space configured to receive exhaust gas from an exhaust pipe of the exhaust system such that the exhaust gas flows through the interior hollow space. The heating element is positioned within the hollow space and including a first end and a second end. The heating element forms a zig-zag shape extending in a radial direction relative to the central axis.

A heating device capable of heating a processing liquid stably and efficiently is provided. The heating device comprises a first unit heater including a first flow path, a second unit heater including a second flow path, and a first tube connecting the first unit heater and the second unit heater, wherein a processing liquid flows through the first flow path, the first tube, and the second flow path, and is heated by the first unit heater and the second unit heater, wherein the first unit heater comprises a first pipe extending along a first direction and including the first flow path formed therein along the first direction, a first input terminal formed on a surface of the first pipe and extending in the first direction, a first output terminal formed on a surface of the first pipe, extending in the first direction, and spaced apart from the first input terminal, a plurality of first heating wires spaced apart from each other, formed on a surface of the first pipe, and connecting the first input terminal and the first output terminal.
