A tobacco smoke filter for use with a cigarette comprising a tube having a conical disc at its upstream end adjacent the tobacco. A capillary orifice through the apex of the conical disc permits discharge of tobacco smoke from the cigarette at high velocity into a downstream chamber for sublimation of alkaloids and other harmful matter to solid particles by rapid expansion. A parabolic disc is positioned in line with the high velocity jet to trap the solid particles and reverse flow to promote turbulence. The disc has a periphery closely adjacent the inner wall of the tube to promote a high speed flow around its edge. The resulting turbulence causes additional deposition of solids on the disc's downstream face. A tube integral with the disc extends to a circular opening in the downstream end of the tube for discharge of filtered smoke. Certain surfaces in the filter, such as the upstream side of the disc, may be coated with a catalyst to enhance a beneficial chemical reaction of constituents in the tobacco smoke.

The disclosure illustrates a receiver for the focused beam component of solar radiation. The receiver comprises an elongated element of heat insulating material and an elongated heat conductive element secured to the insulating element along its marginal edges to form a passage for heat transfer fluid. The heat conductive element has a concave or convex outer surface that has portions normal to reflected solar radiation coming from a range of different directions. Preferably the heat conductive element is formed from a thin walled extrusion which has an internal fin to maximize the surface area of the passage for the heat transfer fluid.

The disclosure illustrates a receiver for focused solar radiation. The portion of the receiver in the path of the reflected radiation has a microporous surface to enhance reception of solar radiation while the remainder of the surface has a highly polished receiver to minimize radiation losses.

The disclosure illustrates an elongated receiver for a solar energy collector of the focusing type. The heat transfer fluid passage in the receiver contains an element having a plurality of tines to promote turbulence and a tube plugged at both ends to direct the heat transfer fluid only along the walls of the receiver that are exposed to solar radiation. Both treatments to the passage increase the heat transferred to the fluid.

The disclosure illustrates a solar collector comprising an evacuated generally rectangular glass shell of a configuration commonly used for television tubes and a flat plate receiver having a black chrome surface positioned within the shell. A conduit in heat exchange relation to the plate has a single inlet and outlet for heat exchange fluid which extends through an insulating seal in the neck of the glass shell. This configuration permits a far greater collector surface area than prior evacuated cylindrical tube configurations.

The disclosure illustrates a flat plate solar collector comprising a vacuum formed tray, of low conductivity material, such as ABS, of sufficient thickness to form a structural support. A layer of glass beaded foam is placed in the tray. A receiver of layers of thin copper with heat transfer fluid passages is positioned over the glass beaded foam. Single or double glass glazing is provided to cover the tray and reduce heat losses. Foam insulating material on the outside of the tray further minimizes heat losses. The receiver and glass beaded insulating material are secured to the tray which forms a low cost, easily manufacturable structural base for the collector.
