There is also provided an aerosol generating device including a housing configured to receive an aerosol-forming substrate, a heating element configured to heat a portion of the substrate, and a positioning mechanism configured to move the heating element from a first position next to a first portion of the substrate, to a second position remote from the substrate, and then to a third position next to a second portion of the substrate.

An apparatus for inducing drive is shown that includes a primary drive shaft and four secondary drive shafts. The primary shaft and secondary shafts are fitted with magnets that are oriented such that when the primary shaft is rotated the secondary shafts are caused to rotate due to attractive or repulsive forces. The primary shaft is connected to and rotated by a rotational energy source such as a motor powered by electricity or a battery, although any source of energy to cause rotation of the primary shaft may be used. Each secondary shaft is fitted with two annular magnetic discs that are oriented to vertically support the weight of the shaft (and any attachments/fittings thereto) above the alternating or generating device. The discs can be arranged to provide either an attractive or repulsive magnetic force between them.

A portable hot water heater for larger-scale applications including emergency use, situations involving hazardous materials, and the like. The hot water heater advantageously efficiently and rapidly heats large quantities of water for providing a stream of hot water for immediate use. The hot water heater includes a pump that can draw water from any suitable water source, a power source, a heating assembly that quickly and efficiently heats the water as it flows through the heating assembly. The heating assembly is attached to a shower head or other fixture.

A pipeline for transmitting oil or other substance which forms a solid residue such as wax when the substance is cooled, as in a subsea oil pipeline. Pass a tube through the interior of the pipeline, e.g., at the wall of the pipeline. Transmit heated liquid or water through the tube for heating the material being passed through the pipeline to a temperature which avoids or eliminates the solid residue and for heating the pipeline.

The various embodiments of the present system disclose a system for an optimal cooling by a thermoelectric cooling module and an electric fan thereof. The system comprises a thermoelectric cooling module, an electric fan and a housing. The thermoelectric cooling module comprises a plurality of thermoelectric sub-modules, a hot side management module, a cold side management module and an integrated control module. The present invention provides an optimal cooling on the basis of an external weather condition. The present invention further provides an optimal cooling by implementing an efficient fluid circulation mechanism. The present invention also provides a dynamic management over the working of various modules of the said system.

A compact reversing flow catalytic converter with protection from overheating includes a valve unit which directs exhaust gases through a container filled with catalytic material to permit a bypass of catalytic material when a temperature of the material exceeds a predetermined threshold. The container defines a U-shaped gas passage that communicates with two ports at the top of the container. The valve unit is mounted to the top of the container and includes an intake and an exhaust cavity. The valve unit includes a valve disk having two openings therethrough. The valve disk rotates around perpendicular central axis between a first, a second and third positions. When overheating of the catalytic material is predicted, a controller relinquishes control of the valve disk and a center return mechanism rotates the valve disk to a third position, in which each of the openings communicates with both ports so that the exhaust gas flow bypasses catalytic material. The catalytic material is thus protected from damage due to overheating. The advantage is a compact, reliable, highly efficient catalytic converter that is inexpensive to manufacture, durable, and adapted for extended service life. An alternate version of the compact reversing flow controller is also described wherein the valve unit and container are essentially as described above but the valve disk is a four position disk with the fourth position blocking communication between the valve housing and the container isolating the monolith so that maximum heat is retained during engine shut down. The valve is driven by a stepper motor that moves and holds the valve to its four positions including block, bypass, forward and reverse flow. The alternate version also replaces the oxidizing flow-through monolith with an oxidizing filter trap and adds a fuel injection system under control of the controller so that measured amounts of fuel can be injected into the valve inlet to enhance oxidation.

A microwave water heating system includes a metal casing having an outer wall defining an interior casing chamber. An inner housing is positioned within the casing and includes an outer wall displaced from the casing outer wall to form an insulating vacuum space. The inner housing includes an inlet port connected to an upstream water source and an outlet port connected to a downstream conduit. The casing and inner housing include generally spherical configurations. The inner housing is configured to induce a vortex of a water stream flowing between inlet and outlet ports. At least one magnetron is mounted to the casing for transmitting microwaves into the inner housing for heating the water stream at the vortex. A float valve in the inner housing allows the water stream to flow and be heated upon demand as the valve operates according to upstream and downstream pressure differentials.

A shallow foundation form and method of using are provided. The form is useful for pouring concrete slab foundations and results in a frost protected foundation with improved thermal characteristics. The form may include brackets to hold rebar at various locations. The brackets are designed to avoid the use of fastening devices, such as wire ties. When used to pour a concrete foundation, the form and brackets reduce construction material input costs, reduce the amount of skilled labor required, and reduce the amount of time required to pour a foundation.

Exemplary embodiments provide a movable sweat hearth for use with a metal melting furnace having a wall provided with a metal-loading entrance. The sweat hearth includes a hearth body movable relative to the furnace into and out of contact with the wall of the furnace at the entrance. The body has exterior walls enclosing a hollow interior except at a furnace-engagable side wall of the hearth body provided with an opening communicating with the interior. The interior has a floor adapted to support a charge of scrap metal, and the opening is positioned relative to the floor to allow molten metal to drain from the interior through the opening. The floor is arranged at an angle to horizontal to slope in a downward direction towards the opening when the container is moved into sealing engagement with the wall of the furnace with the opening aligned with the furnace entrance. Other exemplary embodiments relate to a combination of a movable sweat hearth as described above and a metal melting furnace having a front wall provided with a furnace entrance.

A cooking apparatus suitable for outdoor use including a substantially ellipsoid or ovoid housing which at least partially defines a cooking area within the same. The housing is substantially formed from aluminium.

A solar thermal collecting system captures solar radiation into a vessel containing an opaque or partially opaque fluid medium. The solar radiation is reflected and intensified using interior parabolic reflectors inside the vessel to generate hot zones throughout the fluid medium; and the generated heat in the fluid medium is transported to a separate system designed to utilize the heat with minimal heat loss. The system of the present invention comprises a vessel that contains the fluid medium. An at least partially transparent or translucent lid enables passage of solar radiation into the vessel. The lid may have integrated solar panels to generate power from solar radiation. Multiple reflective parabolic reflectors integrated in the vessel focus solar radiation throughout the fluid medium to create hot zones that intensifies heating the fluid medium. The vessel is resilient to withstand variances in pressure and temperature. After fluid medium absorbs heat, an insulated conduit transports the heated fluid medium for storage or other beneficial uses such as conversion to power with minimal heat loss.
