摘要:
A collector of waves, 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 panel 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.

A hollow ball-like construction is disclosed as including a plurality of hollow wedges having a variety of different shapes and angles, which wedges are mounted on a central disc to form a unitary assembly. Cylindrical and spherical wedges of different configurations are utilized to complete the constructions into a plurality of outlines, such as a trapezoid, a rhombus, a square, a triangle, a pentagon, a hexagon and other irregular outlines.

An automobile fuel tank cap retaining device includes a flexible member interconnecting a pair of mounting ends having adhesive surfaces. One end of the device can be adhesively secured to a cap and the other end to a stationary surface so that when the cap is removed from its reservoir inlet the cap will hang adjacent thereto.

摘要:
A light concentrator of paraxial rays emanating from at least one point source and/or of multidirectionally dispersed rays, employing at least two confocal warped shells generated by the revolution of a conic section, has in a preferred embodiment two truncated confocal paraboloids, an outer of a larger dimension and an inner of a smaller dimension, mounted about a common axis with their vertices in line on one side of the common focal point of their surfaces. The inner face of the outer shell and the outer face of the inner shell are developed at least over selected portions thereof as reflectors. The vertex of the outer shell has an exit orifice for the passing of a concentrated beam therethrough, said beam originating in unconcentrated form from an area spaced opposite from the open ends of the paraboloids.The direction of paraxial rays from the source, the arrangement of the confocal warped shells, and the angles of the reflectors are correlated into a multiple reflection system to produce the desired concentration and emission of a high-intensity beam through the vertex of the outer shell.A paraxial ray reflected from the interior face of the outer paraboloid toward its focal point, impinges on the exterior face of the inner paraboloid, having the same focal point, and is reflected from there parallel to the direction of the original light ray and the common axis of the two paraboloids in continuous or stepwise successive reflections, whereby the light intensity of each ray contributes to the light intensity of the resultant common beam.
