Abstract: Disclosed are methods and apparatus for smoking food such as meats, under pressure. In many examples, the source of pressure, and some heat, will be an internal combustion engine; with the exhaust from the engine communicated to a pressure chamber in which the meat or other food is placed. A separate heat source will be associated with the pressure chamber to provide increased temperatures within the pressure chamber. In some examples, the heat source can be a gas flame source, such as either propane or liquid natural gas.

Abstract: Systems and methods are provided for thermal control using vascular channels. Vascular channels are incorporated in a network within a component. The component is a part of a manufactured environment configured for occupants. A fluid circuit is connected with the vascular channels and circulates a fluid through the component to alter a thermal state of the component.

Abstract: A rainwater recycling system for a motor vehicle includes a rainwater collector, a rainwater reservoir connected to the rainwater collector and a heat exchanger to heat rainwater in the rainwater reservoir. A related method of recycling rainwater is also disclosed.

Abstract: A fuel-fired combustor includes a housing with a combustion chamber. The housing has an inlet and an outlet. A fuel inlet to the housing supplies fuel to the combustion chamber. An igniter ignites a mixture of exhaust gas and fuel to produce a flame for increasing an internal temperature. At least one sensor measures or monitors at least one combustor characteristic and generates a corresponding combustor characteristic signal. A controller receives the combustor characteristic signal, compares the combustor characteristic signal to a predetermined combustor criteria and generates an output signal to change at least one combustor operating condition if the combustor characteristic signal varies from the predetermined combustor criteria.

Abstract: Various embodiments of a gas valve and a sear-zone gas burner are described and claimed herein. One embodiment described herein relates to a cooking chamber with a cooking surface, which has at least two portions including a first portion and a second portion. The first and second portions of the cooking surface each have at least one heat source disposed underneath. The at least one heat source for each cooking surface in turn has a highest setting such that a first maximum heat output is provided to the first portion of the cooking surface when set at the highest setting and a second maximum heat output is provided to the second portion of the cooking surface when set at highest setting, wherein the second maximum heat output provided to the second portion is greater than the first maximum heat output provided to the first portion of the cooking surface.

Abstract: The present invention provides a heating device of a drinking fountain in a car. It has a helical pipe, a wire net, an iron container, fireproof mud and a car exhaust pipe. The helical pipe is installed outside the car exhaust pipe and the wire net is used to cover the pipes. The iron container covers the wire net, the helical pipe and the car exhaust pipe. Fireproof mud is poured into the reserved space in the iron container and it is sealed completely. One end of the helical pipe is a water outlet, while the other end is a water intake. The car exhaust pipe generates high temperature and heats the helical pipe which is insulated by fireproof mud. When users push the drinking fountain switch, a motor will operate to pump out water from water storage. The water is heated when it goes by the helical pipe.

Abstract: A convection oven for use in a food delivery vehicle comprises an oven cavity with an air inlet and an air outlet, an air feed conduit for feeding an air feed into the oven cavity through the air inlet and a heating arrangement for heating the air feed before it is fed into the oven cavity, the heating arrangement comprising a heating device that is electrically powered and being arranged to maintain a temperature of at least 130° C. in the oven cavity. A food delivery vehicle may comprise such an oven and the oven may be heatable from an electric current provided by the engine of the vehicle.

Abstract: A modular portable gas grill including an energy management system for even temperature control, enhanced flavor devices, and electronic, electro-mechanical, or mechanical controls is provided. The grill includes a touch control system including sliders or knobs providing efficient, precise and accurate control. Heat and flame deflecting shields provide an improved air draft, heat, and flavoring system and can be removed for cleaning. Modular design construction and a quick-connect gas manifold permit the addition of additional components at a later date such as a rotisserie, and a smoke chute for flavoring. Burner shields protect the burner and flame from greases and liquids. The grill also features the ability to easily convert between propane and natural gas fuel and an electronic reigniting system providing individualized control to the burners. The grill also features a dual fuel mode giving a user the ability to use propane or natural gas along with charcoal or other solid fuel.

Abstract: Methods for cyclone boiler flame diagnostics and control, including methods for monitoring the operating state of a cyclone furnace using linear and nonlinear signal analysis techniques, including temporal irreversibility and symbol sequence. Adjustments may be made in the air flow distribution to optimize performance. Signals for the main flame and lighter scanners are relatively independent, thereby allowing for independent control of the primary air flow to the burner and secondary air flow to the barrel.

Abstract: A roasting oven and a heating device thereof able to produce three-dimensional radiation heating of food material, mainly including a fire tray, and an igniting platform is formed at a central position thereof, which enables igniting solid fuel material thereon. After igniting, the fuel material is made to drop into lateral combustion troughs using any method, and the vacated igniting platform then provides for holding and roasting food material thereon. Heat radiation waves produced by the burning fuel material in the lateral combustion troughs form a three-dimensional angular heat radiation side wall that is able to realize synchronous omnidirectional roasting of the surface of food material. Moreover, the present invention enables easy cleaning away of ashes after finishing roasting.

Abstract: Apparatus for keeping hot and for transporting prepared dishes, in particular pizzas, from the producer to the consumer, using a motor vehicle equipped with a thermally insulated container, which in its lower portion is provided with a heat exchanger using which the heat supplied by an external source is transmitted to the air in the container by heat conduction and radiation, characterised in that the container is laid out as an essentially square box at the bottom of which the heat exchanger is incorporated. One of the four lateral walls of the box is linked to the box, forming a door which is sealed and gives access to the container. The other three lateral walls and the top cover of the box are laid out as double walls enclosing air interspaces, which on their sides are all mutually interconnected and towards the front, towards the access door, are connected to the inner chamber of the container.
