A system for the production of molten salt. The system can have a preparation tank configured to melt raw salts, and a bubbler system in communication with the preparation tank. The bubbler can be configured to maintain vacuum conditions within the preparation tank and to remove gases from the preparation tank. A method for producing molten salt includes a step of providing a system for the production of molten salt. The system can have a preparation tank configured to melt raw salts, and a bubbler system in communication with the preparation tank. The bubbler can be configured to maintain vacuum conditions within the preparation tank and to remove gases from the preparation tank. Then, the method can include inserting raw salt into the preparation tank, and heating the raw salt to form molten salt. Then filtering the molten salt, and storing the molten salt.

A semi-finished product of an electric heater device has a casing body (2) defining a housing for at least one electric heater. The casing body (2) has a first or predefined configuration, in particular a substantially planar, or plate-like, or two-dimensional configuration, and is prearranged for being folded in substantially predetermined areas (1a), which define in the casing body (2) a plurality of regions (4, 5, 6) that are at least in part relatively stiff and are suitable to be folded with respect to one another in one said folding area (1a). In this way, a second or different configuration, in particular a substantially three-dimensional configuration, can be bestowed upon the casing body (2).

Devices, systems, and apparatuses for heating a liquid are disclosed herein. In one embodiment, a heater includes a base comprising a generally planar surface and at least two heater pillars and a sensor pillar configured on the base. The at least two heater pillars each comprise heating elements. The sensor pillar includes a thermal sensor. A mixing element is configured on the generally planar surface of the base and is coupled to a mixing motor. When powered, the heating elements of the heater pillars are configured to generate heat and the mixing motor is configured to cause the mixing element to rotate.

According to an embodiment of the present invention, provided is an electrode heating device including: a device housing; an electrode heating unit including a central conductor, an internal conductor disposed to form a gap inside the central conductor, and an external conductor disposed to form the gap outside the central conductor, and received and installed in the device housing; and a control board received and installed inside the device housing, and applying power to an electrode of the electrode heating unit, and controlling a heat generation operation of the electrode heating unit.

A glass-tube heater includes a glass tube, a cap, and a temperature display unit. The glass tube is provided therein with an off-water protection sensor or a tipping switch, a control circuit board, one of a TRIAC and a relay, and a heating element. The control circuit board includes a control unit (which is an MCU or a comparator). All the components that are disposed in the glass tube are electrically connected to form a control circuit. Devices for temperature control, detection, and heating are all disposed inside the glass tube. The off-water protection sensor is operable to detect if being removed out of water for controlling the heating element to carry out heating or not, thereby ensuring quick termination of heating upon removal out of water. The tipping switch is operable to control the heating element from heating in case of excessive tipping of the heater.

An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket protrudes into the heating chamber as a heating rib that may taper towards its lower closed end. A PTC heating element is received in the receiving pocket. The PTC element includes at least one PTC element and conductor tracks which energize the PTC element with different polarities which are electrically conductively connected to the PTC element, and which are electrically connected in the connection chamber. A pressure element also is received in the receiving pocket. Heat extraction surfaces of the PTC element are held in the receiving pocket abutting against oppositely disposed inner surfaces of the receiving pocket. The pressure element has at least one cambered surface segment projecting toward the inner surface or toward the PTC element.

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. A system may include assembly cells each including an assembly track and assembly carriages that ride thereon and which engage components of partially-assembled cartridges. A transfer apparatus may transfer partially-assembled cartridges between the assembly cells. In another example system, cartridges may be assembled on platforms on a rotary track. The platforms may include assembly grippers with sequentially-opening clamps configured to receive the components of the partially-assembled cartridges. Related methods are also provided.
