US Patent:

43345247, Jun 15, 1982

Filed:

Apr 18, 1980

Appl. No.:

6/141475

Inventors:

Robert W. McCullough - Tarrytown NY
Thomas A. Hewett - Chappaqua NY

Assignee:

Union Carbide Corporation - New York NY

International Classification:

F24J 302

US Classification:

126449

Abstract:

A solar heater including a housing having a transparent front wall for passing incident solar radiation, a radiation absorbent collector element positioned in the housing and arranged to accept incident solar radiation passing through the front wall, means for passing a fluid medium to be heated through the housing in heat transfer relationship with the collector element and a transparent heat trap disposed in the housing between the collector element and the front wall. The heat trap is made from a cellular structure containing a multiplicity of adjacent cells having walls which are integrally formed with the walls of other cells in one continuous piece from a thermoformable material. The thermoformable material used for the heat trap may be glass or a clear plastic composition which is opaque to infrared radiation emitted from the collector element.

US Classification:

126441

Abstract:

A solar heater including a housing having a combined transparent front wall and heat trap, a radiation absorbent collector element positioned in the housing and arranged to accept incident solar radiation passing through the front wall, and means for passing a fluid medium to be heated through the housing in heat transfer relationship with the collector element. The combined front wall and heat trap are integrally formed in one piece from glass or a clear plastic composition which is opaque to infrared radiation emitted from the collector element.

International Classification:

G01J 142
G01N 2164

US Classification:

250372

Abstract:

A source produces light, preferably in a wavelength band of approximately 185-200 nm and in pulses at a suitable frequency (e. g. , 100 Hz). The light may be directed in a progressively diverging beam into the atmosphere for a Rayleigh scattering by molecules in the atmosphere in the 185-200 nm wavelength band and for fluorescence by particular molecules (e. g. oxygen) in the atmosphere in another wavelength band (e. g. 210-260 nm). The Rayleigh scattered light and the fluorescent light may pass in a progressively converging beam to two detectors, one responsive to the Rayleigh scattered light to produce first signals and the other responsive to the fluorescent light to produce second signals. Optical elements may prevent the second detector from responding to the fluorescent light and the second detector from responding to the scattered Rayleigh light. A data processor processes the first and second signals to provide outputs representative of the atmospheric pressure and temperature.

International Classification:

F24J 302

US Classification:

126436

Abstract:

A solar air heater including a housing having a transparent front wall and an inlet and outlet for establishing a flow path for a gas such as air to be heated and a porous radiation absorbent collector plate positioned across the flow path and arranged to accept incident solar radiation passing through the front wall wherein a radiation trap is placed inside the housing either adjacent to the front wall, directly on top of the collector plate or between the collector plate and the front wall. The radiation trap has a cellular structure such as honeycomb and is made from a material which is light-transmitting but opaque to infrared radiation emitted from the collector plate in a direction toward the front wall. When the radiation trap is placed adjacent to the front wall the trap can additionally serve as an air buffer layer. In this instance, however, the radiation trap must be maintained in at least firm mechanical contact with the front wall and preferably the trap is actually bonded to the front wall.
