Abstract: A conical magnifying stage lens M:RT-TR-2RT:C comprising four component lenses with concave conical, convex conical and planar sections (faces). An afocal indicent beam from the object is refracted and enlarged two times and emitted parallel to the incident beam and the optic axis. The stage lenses can be stacked vertically to produce multiple magnification of images.

Abstract: A single conical lens with a planar section (face) which transmits an annular incipient beam, a concave conical reflective section which reflects the beam, and a concave conical section which refracts the beam, forming a concentrated circular whole beam which is emitted parallel to the optic axis.

Abstract: Two reciprocating cylindrical drive cams, each with a continuous spiral groove, mounted on a splined shaft, a driven cylindrical cam with two continuous spiral grooves mounted on a parallel shaft, and two reciprocating pins mounted in an intermediate housing between the drive cams and driven cam. The upper ends of the pins engage the grooves of the drive cams, and the lower ends of the pins engage the grooves of the driven cam. When the drive cams are locked together on the splined shaft, the drive cams revolve and the grooves impart reciprocating motion to the pins which impart revolving motion to the driven cam. When the drive cams are allowed to reciprocate on the splined shaft, the drive cams do not revolve and no motion is transmitted to the pins or to the driven cams.

Abstract: A bilateral prism having two angular wedge faces which receive two convergent incipient beams of indirect sunlight and having two angular V-groove faces which emit a concentrated sheet beam. The prism is mounted on a rectangular block with angular lateral sides. The angle of the sides is such that two or three prisms can be mounted side by side with adjacent sides in contact so that the projected concentrated sheet beams converge onto a heat duct through which water or air circulate.

Abstract: A hollow transparent glass prism having a planar face which receives a rectangular solar beam perpendicular thereto and having two angular wedge faces which refract the beam to form two concentrated convergent rectangular beams.

Abstract: The disclosure is a hollow glass cylinder with an aluminized interior for the reception, temporary retention and study of concentrated solar radiation. The cylinder is toroidal in shape, with an inside wall and an outside wall joined by two end walls. A concentrated beam of high intensity is directed into the cylinder through a rotary light valve, with the line of entry of the beam forming a tangent with the inner surface of the outside cylinder wall. The beam is reflected around the inner surface of the wall, with the direction of propagation at the end of each revolution being parallel to the beam being received through the light valve.

Abstract: A conical beam concentrator consisting of a series of six component lenses which receive a convergent conical beam of diffused sunlight and emit a concentrated circular whole beam. There are six annular lenses aligned on the veritcal optic axis, as follows; an upper lens with a convex conical section which forms the apex of the concentrator, and five lower lenses with inset convex conical sections of graduated increased diameters. Each lens consists of twelve sections separated by radial walls which are covered by an opaque coating of paint which intercepts radiation not perpendicular to the convex conical sections of the lenses. The upper and lower conical walls of each lens are also covered by an opaque layer of paint to intercept extraneous radiation.

Abstract: An upper component lens which transmits and refracts a circular whole incipient beam into a lower component lens which transmits and refracts the beam, forming a divergent lateral beam in the horizontal plane.The beam concentrator is to be used as the lower stage of a pipe cutter.

Abstract: An upper stage lens which receives a convergent conical incipient beam and emits a concentrated whole beam into a lower stage lens which emits a concentrated whole beam. The upper stage lens is located on the roof of a building and projects a beam through a light conduit to the lower stage lens in the room below. A chamber into which various colored water solutions can be pumped is located in the conduit above the lower stage lens.

Abstract: Five concentric annular conical beam concentrators mounted above a black-water heat-transfer tank through which domestic household water circulates in tubes. The conical beam concentrators receive convergent conical incipient beams of diffused sunlight and emit concentrated annular beams into the black water. The black water absorbs the heat of the beams and transfers the heat to the tubes through which the domestic water circulates. The panel is designed for use in cloudy overcast areas which receive little direct sunlight during the winter months.

Abstract: A convex-concave conical lens which refracts a convergent conical incipient beam of diffused sunlight and a double convex conical lens which refracts and emits a spectral beam. The blue through red portions of the spectral beam are reflected laterally and the ultraviolet and violet portions are emitted through a conical aperture in the base of the concentrator.

Abstract: A convex conical-concave conical lens with louvers for the reception of convergent conical beams and the interception of nonconvergent conical beams, for use in convergent conical beam concentrators which receive incipient beams of diffused sunlight.

Abstract: An upper stage lens which receives a convergent conical incipient beam and emits a concentrated whole beam into a lower stage lens which emits a concentrated whole beam. The upper stage lens can be any one of the spectral colors.

Abstract: A stator comprising a cylindrical permanent magnet and a helical charging coil wound thereon and embedded inside a cylindrical plastic casing, and a reciprocator comprising two cylindrical electromagnets with helical charging coils wound thereon and a helical charging coil embedded inside a hollow cylindrical plastic casing enclosing the stator. The two electromagnets are mounted at opposite ends of the permanent magnet and are axially aligned therewith, with an intervening space to allow for longitudinal movement of the electromagnets. The helical charging coil occupies the electromagnetic field of the permanent magnet.The helical charging coils of the electromagnets are wound in opposite directions so that when one electromagnet attracts one end of the permanent magnet, the other electromagnet repels the opposite end.

Abstract: A flat circular plate glass window and a conical circular metal disk mounted below the window so as to form an expansion chamber through which a black-dye solution of water and alcohol circulates. Water enters the chamber through a 1 mm peripheral gap between the window and disk and exits through a vertical pipe located at the center of the chamber 15 mm below the window. The heated water expands outward against the tapered walls of the chamber and deflects in the direction of flow, thereby increasing the rate of flow.

Abstract: A glass or metal wall forming an involute curve through three revolutions around a central axis parallel thereto, mounted between parallel front and rear walls perpendicular thereto and forming a chamber which is curved in cross section and rectangular in longitudinal section.The chamber is reflective in the interior and communicates with the exterior through a rectangular port formed by the terminating involute wall and the section of involute wall adjacent thereto.A concentrated rectangular beam of sunlight from a prismatic beam concentrator is projected into the chamber through the port. The beam undergoes further concentration as it curves in toward the center of the concentrator, where it is emitted through an aperture in the rear wall, forming a concentrated circular beam parallel to the axis of the concentrator.

Abstract: A cylindrical glass prism with one planar entry face which refracts incident beams and with multiple exit faces perpendicular to the refracted beams which are emitted without refraction and without reduction in width. The prism can be revolved on a concave cylindrical base.

Abstract: Two single-refraction prisms which produce enlarged or reduced images in two dimensions. The prisms have cylindrical members which can be revolved so as to emit the refracted beams without additional refraction. The first prism enlarges the image in the vertical dimension, and the second prism enlarges the image in the horizontal dimension.
