Sherman, Jr, B F

A collector of waves is disclosed, such as of solar radiations entering from any direction, concentrates them upon a receiver that converts them to useful purposes. Moderate concentration factors are achieved without the necessity of tracking the sun. The reflective surface of the collector is a semicircular arc developed by rotation about an axis either in the plane of the arc passing through the center of curvature to form a hemisphere, or in the plane of the arc and tangent to one end to form a hemitoroid with a central cusp, or about some other axis; or some combination of these shapes. The device is compounded to provide an increased concentration factor. Means are taught for adapting the device to heat-collecting plates, heat pipes, or photovoltaic conversion devices (solar cells) of either disc, ribbon, or tube construction and for installing the device on surfaces of buildings with or without the capability of tracking the sun.
