Abstract: An exhaust recovery system vents exhaust from an exhaust pipe of a vehicle, located in an enclosed structure, as the vehicle is driven out of the structure. The system includes a coupling attached to a detachably connectable coupling support assembly to support the coupling proximate the vehicle exhaust pipe. An elongate flexible hose has a first end and a second end, where the first end of the hose is connected to the coupling. The second end of the hose is connected to an extendable assembly. A first member is interconnected between the support assembly and the extendable assembly that when tensioned as a result of the vehicle being driven out of the structure extends the extendable assembly.

Abstract: An exhaust recovery system to vent exhaust from an exhaust pipe of a vehicle within a building. A coupling is detachably connectable to the exhaust pipe of the vehicle. An elongate flexible hose is interconnected between the coupling and a telescoping assembly. The telescoping assembly includes a plurality of tubular members slidably engaged within one another. As the vehicle is moved away from the telescoping assembly it causes the tubular members to slide with respect to one another permitting the vehicle to exit the building while exhaust from the vehicle passes through the hose and the telescoping assembly.

Abstract: A radiant space heating element (12) in the shape substantially of an equilateral triangle for providing uniform distribution of heat by radiation from an interior space (32) that is a passage for an energy source such as hot water, steam, hot stack gases or any other source of infrared energy. The heating element (12) has two radiating surfaces which meet at a vertex (20) so that there is a substantial uniformity of temperature over an area on either side of a line directly under the heating element which is nearly equal to five times the separation of the heater element from the surface. The heating element (12) has insulation (14), a web element (36) that acts both to support the insulation (14) and as a reflector, and a bracket (16).
