Abstract: A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

Abstract: An outdoor cooking grill assembly having a side gas oven which is positioned at substantially the same elevation as the grill and preferably also includes a gas burner assembly of the same type used in the grill.

Abstract: A lightweight, portable filter system that is especially adapted for use in commercial kitchen cleaning services such as hoods used in commercial kitchens is described. The invention is defined by a container adapted for holding a filter and which has a drain opening that may be connected to the usual drain. A filter is suspended in the interior of the container with a special structure that allows for quick and easy insertion of the filter and removal of the filter when it is spent and the top of the filter is open to define a relatively large opening. In use, the tarp that is used to isolate a hood during cleaning is tucked into the opening into the filter so that effluent that flows from the hood during cleaning, and the cleaning fluids (water, degreasers, etc.) are channeled into the filter. The material used for the filter is selected for the particular type of cleaning that is being done, and in any event removes the desired compounds from the effluent stream.

Abstract: A cleaning system for a cooking range exhaust having a range hood, a backsplash, and an exhaust flue for exhausting cooking effluent is disclosed. The cleaning system can include a fluid delivery system constructed for partial placement within the cooking range exhaust. The fluid delivery system can include a hood spray conduit constructed for placement within the hood and comprising spray openings for directing a degreasing composition to the backsplash. The fluid delivery system can also include a flue spray conduit constructed for placement within or outside the exhaust flue and comprising at least one spray opening for directing the degreasing composition to an interior surface of the flue. The cleaning system can include a pump system constructed for conveying the degreasing composition from a degreasing composition source and through the fluid delivery system. A method of cleaning a cooking range exhaust and a self-cleaning exhaust system are also disclosed.

Abstract: A kitchen hood assembly includes a combination hood cleaning and fire suppression system. The hood assembly includes a hood structure and a riser connected thereto. An exhaust blower forces an exhaust stream of air into the hood and through the riser. A combination hood cleaning and fire suppression system is incorporated into the hood structure. The combination hood cleaning and fire suppression system includes an elongated spray bar that is connected to a water source and includes a surfactant injector that injects a surfactant into the water being directed to the spray bar. In one mode of operation, the spray bar is effective to clean the hood assembly. In another mode of operation, when a fire is sensed in or in the vicinity of the hood, the same spray bar is utilized to inject an aqueous liquid into the hood to suppress the fire.

Abstract: A method and apparatus (22) for treating culinary gaseous effluents (Eg) carried in an air extraction duct of a kitchen, the apparatus includes: a unit (24) for storing in liquid form a nucleophilic active product (Pa), or odour destroyer, able to fix foul-smelling molecules in the form of inert salts, a nebulizing and diffusing unit (26) which vaporizes or sublimates the active product (Pa) coming from the storage unit, and which diffuses the vaporized or sublimated active product (Pa) in an extraction duct (18), at ambient temperature, so as to minimize the discharge of foul-smelling molecules at the outlet of the extraction duct. A plant including this apparatus is also disclosed.

Abstract: A process and device for removing and oxidizing organic substances from an extracted air stream. The air stream is flowed through a filter which adsorbs the organic material, where the airstream is bypassed around a catalyst until the filter is saturated. At saturation a heater supplies heat to the filter to desorb the organic material. The catalyst is heated by another heater at the desorption period and receives the organic material and extracted air stream to oxidize the organic substances.

Abstract: The invention essentially comprises a scraping device for mounting at the end of a rod, having a body comprising a plurality of radial extending arms. At the ends of each arm is the scraping surface. The construction of this scraping device is such that when the device is positioned in a flue or like structure, debris and incrustations can be scraped therefrom by a reciprocal movement of the scraping device against the surface to be cleaned.

Abstract: A flue cleaning device for cleaning the interior cavity of a flue of the type used with a wood burning stove or the like. The device comprises a laterally extending tubular member in fluid communication with the flue, a slideable chute is mounted in the tubular member which is moveable into interfering relationship with the flue cavity to receive the combustion product debris scraped from the flue walls during a cleaning operation. A cleaning brush mounted on a cable and suspended from a pulley in an upper portion of the flue permits the brush to be moveable up and down the flue as well as being retained when desired within the laterally extending tubular member. The brush is moved by a winding device mounted within the laterally extending tubular member and operable from outside the tubular member. Discharge apparatus for receiving combustion materials and chute movement apparatus are also described.

Abstract: A heating system for heating a confined area with an open-hearth wood-burning fireplace. A fireplace jacket is provided which comprises a multi-chambered double-walled arrangement or a grate member. Log supporting portions of the jacket slant upward slightly in order to prevent a pinging sound by creating convectional force when water is circulating therethrough. The grate member includes first and second headers formed from prisms with triangular bases, and water conducting pipe portions extending on three sides of a fire burning in the open-hearth fireplace. The fireplace jacket is readily utilizable with a conventional forced-air furnace in association with a heat exchanger disposed in the furnace cold air return. Combustion air for the fire is provided from an area external of the confined area to be heated by the heating system.

Abstract: A nonmetallic disc has a plurality of kerfs extending radially inwardly from the outer periphery. Magnets are disposed in the bottom of the kerfs so as to form a space between the magnets and the outer periphery of the disc to collect magnetic particulate material in this space. An eyelet is provided for attachment to a cable for pulling the disc through a pipe to remove magnetic debris therefrom.
