Abstract: The ductless air handling system draws return air from a low level and discharges conditioned supply air at a high level, thereby de-stratifying and covering a large area without the need for field-installed ductwork. The outlet is composed of a series of vertical and horizontal vanes with respective adjustable louvers and flaps as well as an integral turning vane. This outlet turns the airflow from vertical to horizontal, straightens the airflow and subsequently directs the airflow for uniform distribution throughout the space without the need for ductwork. Further, a germicidal irradiation chamber within the conduit connecting the base to the outlet can disinfect air as it is circulated by the air handler.

Abstract: A metal panel generally constructed from sheet material, such as sheet metal, and assemblies thereof which can be used to construct an enclosure, and specifically a no-through-metal enclosure. There is also provided methods for constructing a floor, walls, and roof of a no-through-metal enclosure utilizing such panels or construction techniques. The construction can still utilize metal fasteners such as rivets, bolts, or screws for maintaining strength which still maintaining the no-through-metal construction.

Abstract: A wall panel which can be used to provide a lower, more rigid, perimeter wall to an air supported structure. The wall panels may be attached to the earth via a hinged connection to provide for improved ease of raising the air supported structure and to allow for flexing, or may be rigidly attached. The wall panels will generally be modular and interchangeable.

Abstract: An improved combustion chamber comprises a shell having a circular array of integral teeth formed at one end thereof. Shrunkfit onto said shell end at or near the roots of the teeth is a ring. The toothed end of the shell is received in an opening in a sheet header so that the ring engages against the header sheet and a continuous weld bead is formed between the ring and the header sheet all around the shell. The shell teeth are bent radially outward and engage the header sheet on the opposite side thereof from the ring so as to be in intimate thermal heat exchange contact with the sheet and these teeth are also welded to the header sheet. The aforesaid engagement between the chamber and rear head minimizes stresses on hot end of the chamber and prolong its useful life. Means engaged around the opposite end of the shell supports, and yet permits lengthwise movement of, that end of the shell.
