Electrical heater systems including one or multiple electrical heaters and a stack for combusting materials leaked into and vented from the electrical heaters. Configurations may include fluid conduits, pressure doors and other equipment for controlling a flow of leaked process fluid between the heater enclosure and the stack. Configurations may also include a purge gas distribution system for purging heater enclosures and preventing thermal shock of electrical heating elements.

A method of operating a tankless water heater for heating a continuous supply of water. The method includes detecting a water flow condition within a heating chamber of the tankless water heater and regulating electrical current to first and second heating elements in response thereto. Both the first and second heating elements are located in the heating chamber, and respectively have first and second wattages, where second wattage is different than the first wattage. The regulating step further includes providing electrical current to the first heating element and not to the second heating element when a first flow condition is detected, and providing electrical current to the second heating element and not the first heating element when a second flow condition is detected, and providing electrical current to both of the heating elements when a third flow condition is detected.

The current invention describes a system and method for relocating densely formed clouds from the location they are formed to another pre-determined and desired location. This is achieved by using air vehicles, or stationary air pods, to change the temperature of the desired location by increasing such temperature. This in tun creates a low-pressure system in that location, which acts as a sink to the air surrounding that location. Such low pressure causes the clouds to be drawn to the low-pressure system, thereby manufacturing the movement of the clouds from the position it was originally formed to another predetermined position. Other aspects of the invention describe a system for forming clouds from sea water or other bodies of water, using a mechanism to allow for utilizing solar energy to achieve the evaporation process faster than the natural process.

A control system for a control-compartment cooling fan of an oven. In one embodiment, the control system includes a sensor for sensing an operating condition of a motor of the cooling fan. The operating condition is selected from the group of a motor current and a motor RPM. A controller is communicatively connected to the sensor and is configured to receive the operating condition from the sensor, compare the operating condition to one or more predetermined tolerances and, when the operating condition exceed at least one of the one or more predetermined tolerances, generate an interrupt command. A heating control element is communicatively connected to the controller and configured to interrupt operation of a heating element in response to receiving the interrupt command. The control system may also include a user interface communicatively connected to the controller.

A mat includes a base and a plurality of studs that together may position an electric radiant heating element within a floor or wall, and may protect the electric radiant heating element as the floor or wall are constructed. The base extends in at least two directions that define a plane. Two or more of the plurality of studs has a cylindrical body that includes a surface and a top, the surface extends from a respective portion of the base in a third direction that does not lie within the plane and that is at an angle between and including 84 and 96 degrees relative to the respective base portion, and the top includes a hole to allow air to pass from outside the stud to an interior region. By using the mat one can quickly install a plurality of positioning devices to hold the electric radiant heating element at desired locations in the floor while the floor is constructed. Furthermore, one can install the mat in odd-shaped rooms or in rooms that will use an electric radiant heating element that is a branch of another room's electric radiant heating element, without having to first wait for installation in other portions of the odd-shaped room or the other room to be completed.

The invention relates to a liquid reservoir (34) for an electronic smoking device (10), an atomizer/liquid reservoir portion (14) with a liquid reservoir (34) for an electronic smoking device (10) and to an electronic smoking device (10) with a liquid reservoir (34). In order to be able to provide gaseous material that has not been atomized by an atomizer (26) of the electronic smoking device (10), the liquid reservoir (34) comprises first and second storage volumes (40, 42) that are each in communication with a liquid outlet (46) or a fluid outlet (50), wherein the liquid outlet (46) and the fluid outlet (50) are arranged one after the other in a longitudinal direction (L) of the liquid reservoir (34).

Methods of manufacturing a heater are provided that generally include forming a laminate having a dielectric layer, a first double-sided adhesive dielectric layer, and a conductive layer. Next, a circuit pattern is created into the conductive layer, and then the circuit pattern is covered with a second double-sided adhesive dielectric layer. The second double-sided adhesive dielectric layer is covered with a sacrificial layer, and then the heater is formed, the heater comprising the dielectric layer, the first double-sided adhesive dielectric layer, the conductive layer, and the second double-sided adhesive dielectric layer. Subsequently, the sacrificial layer is removed.
