A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.

A heated drain or vent pipe system provides a low-cost and efficient temperature regulator for drain or vent pipes that are exposed to freezing temperatures to prevent the pipes from freezing. The heated pipe system includes an embedded resistance wire connected to a transformer that supplies a low voltage of electricity to the resistance wire. The resistance wire heats up due to electricity passing through the wire and transfers that heat to the pipe. The resistance wire is embedded in the wall of the pipe and maintains the pipe at a temperature above freezing. The heated pipe system may include a safety limit switch to disable the flow of electricity to the resistance wires if the pipe is overheating. The heated pipe system can be installed with air conditioning system drains, roof drains, and two-way vents that are exposed to freezing temperatures.

Aspects of the instant disclosure relate to electronic cigarettes; more particularly, to electronic cigarettes including a power supply portion. In various embodiments, the eCig power supply portion includes a sub-assembly housing substantially containing a battery, an airflow sensor, and controller circuitry. Aspects of the disclosure are further directed to an eCig power supply portion further including a hemicylindrical port and/or electrical contacts aligned along a longitudinal axis of the power supply portion.

An inline heater includes a heater core that includes a heat spreader assembly comprising a tubular heat spreader that extends axially along a longitudinal axis and that comprises an external surface. The heat spreader assembly includes a fluid inlet and a fluid outlet. At least one conduit extends helically about the longitudinal axis of the heat spreader between the fluid inlet and the fluid outlet to define a fluid heating flow path that fluidically connects the fluid inlet and the fluid outlet. The heat spreader assembly further comprising an electrically operated heating element for heating the heat spreader.

A novel low profile heater apparatus and method of manufacture is disclosed, which provides a lower assembly including a first sheet, a heating sheet including at least one heating element, a dielectric sheet, an intermediate sheet and one or more electrical leads configured to supply electrical power to the heating element, the electrical leads extending through a lead sleeve of an upper assembly. The upper assembly includes a top sheet with one or more split sleeves securely attached thereto, thereby forming one or more strain relief assemblies configured to prevent damage to the electrical leads. One or more stitches or coupling features securely attach the upper assembly to the lower assembly. One or more retention device are be used to securely retain the low profile heater apparatus to one or more pipes, tubes or conduits of a plumbing apparatus.

The present invention provides an atomizing unit and an atomizing device. The atomizing unit includes a tubular heating assembly and a liquid conducting member. The liquid conducting member is wrapped around an outer periphery of the tubular heating assembly or fitted to an inner peripheral surface of the tubular heating assembly. The tubular heating assembly includes an annular connecting portion, at least two heating portions connected to one end surface of the connecting portion and arranged around the end surface, and electrode portions connected to one end of the heating portions away from the connecting portion. Each side of two opposite sides of one heating portion faces to a corresponding side of its adjacent heating portion with a gap therebetween. The at least two heating portions are connected in series through the connecting portion. The atomizing unit has a high structural strength and is convenient for assembly.

An electric heater with an axial opening for holding an object to be heated includes an electric heating element and a clamping sleeve for generating an adjustable, radial force acting in a direction toward an axis of the axial opening. The clamping sleeve of the electric heating device is penetrated by at least one cut, whose width can be changed by means of at least one clamping device. A component of the clamping device is rotatably mounted or can be rotatably mounted relative to the clamping sleeve about an axis of rotation perpendicular to the axis of the axial opening. This component interacts directly or indirectly with the clamping sleeve so that a rotation of the rotatably mounted or rotatably mountable component of the clamping device changes the width of the cut.

Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.

A tube heater for heating a fluid in an interior of the tube has a stainless steel cylindrical core. The core ranges about 3 to 300 mm in length and about 100 to 200 microns in thickness with an outer diameter of about 8 to 20 mm. An inner surface of the core has dimples and a conductive coating. A patterned resistive layer overlies the core in a thickness of about 9 to 15 microns. The resistive layer is thin- or thick-film printed about a circumference of the core. Two glass layers surround the resistive layer. Each glass layer is electrically insulative. The glass underlying the resistive layer has a thermal conductivity of more than 2 W/mK while the glass overlying the resistive layer has a thermal conductivity of less than or equal to 0.5 W/mK.
