Abstract: Solar concentrator plant using natural-draught tower technology, in which the tower is, in turn, used as cooling system. The tower houses saturated or superheated steam receivers in cavities with different orientations, with adaptive dynamic control of the heliostat field in order to direct said receivers towards different focusing points, for the production of electricity, process heat or solar fuels or for use in thermochemical processes.

Abstract: A ceiling support box is an interface for coupling two sections of pipe as part of a venting apparatus for a heating appliance. Dual functionality is provided in a single integrated device by having a vent path for exhausting combustion by-products, and a separate air inlet path to draw in combustion air for use by the heating appliance.

Abstract: A venting apparatus includes a projecting member with a projection base, and a mating socket member with a socket base, and first and second ducts in fluid communication with an appliance to vent emissions along an emission flow path. The projection base engages a first one, and the socket base engages a respective other one, of the first and second ducts. The projecting and socket members have default configurations. The projecting member is movable from the default configuration towards a deflected configuration, and biased for return therefrom. The first and second ducts are movable between sliding and locked configurations. In the sliding configuration, the projecting and socket members bear against one another, with the projecting member removed from the default configuration. In the locked configuration, the projecting member is in the default configuration, and secured to the socket member, such that the second duct securely engages the first duct.

Abstract: A waterproofing and humidity control system is provided for a building which includes drain members located in trenches provided in ground beneath and adjacent the basement of the building. A suction and fan and motor assembly is located within a housing positioned within the building. Conduits communicate with the drain members and the motor and fan housing. An exhaust vent is located in the wall of the building spaced from the motor housing and has an air inlet and outlet. A separate conduit or duct communicates with and connects the inlet of the vent with an outlet of the motor and fan housing. The duct may extend between joints in the wall of the building. An adapter conduit is used with the system and is positioned between the motor and fan housing and the duct. The adapter conduit has portions which are offset from each other to allow the fan housing to be positioned in front of a finished basement wall.

Abstract: An interfitting modular metal duct made up of elements forming an inner d, pairs of elements being united by respective collars, sealing between the two elements being provided by a lip gasket and a fold chamber mounted in the female end of an element and bearing against the outside surface of the corresponding male portion.

Abstract: An exhaust gas diffuser interface includes a stainless steel shell with varying levels of insulation. The varying levels of insulation concentrate thermal expansion and contraction at the turbine outlet end allowing it to be connected to the outlet by way of a seal weld. This construction allows expansion and contraction of the diffuser interface in unison with the attached turbine outlet, as well as the diffuser inlet.

Abstract: An exhaust vent adapter is provided for use in a heating system having a plurality of heating units, which allows all heating units to discharge combustion gases through a single exhaust opening. The adapter comprises a body with a plurality of discrete chambers formed therein, each chamber communicating with a separate heating unit. The body of the adapter has a single exhaust opening formed therein, through which each chamber is independently connected to a separate exhaust vent pipe. The vent pipes leading from plurality of the chambers are concentrically arranged, and may be extended through a single opening in either the wall or ceiling of a building in which the heating units are installed. In a preferred embodiment, the body of the adapter has a single divider secured therein, which defines two chambers and segregates the combustion gases from a pair of heating units.
