Patent number: 4770824Abstract: A casting die, for forming a segmented mirror, is formed by the steps including:providing a negative or positive casting of the desired continuous surface shape;cutting the casting into small segments to form non-circular gaps between segment cross-sections;translating the segments relative to one another in a common direction to contact a shaping surface or surfaces, while maintaining constant gap widths between the segments;joining the segments to form a unitary body by adding filler material to the gaps.Type: GrantFiled: August 3, 1987Date of Patent: September 13, 1988Assignee: Roxor CorporationInventor: C.

Patent number: 4750825Abstract: The invention concerns a method of making a segmented mirror, the mirror comprising, in combination(a) a myriad of surfaces carried by a support, certain of said surfaces dimensionally offset from one another in a common direction generally parallel to the general direction of incident radiation to reflected, said surfaces being radiation reflecting sufaces each oriented in such a way that as a group they collectively reflect radiation essentially as they were a continuous reflecting surface,(b) each of said surfaces having a periphery comprising an irregular or repeating series of line segments which are connected, curved or linear, the peripheries of said surfaces, when projected in said common offset direction onto a plane perpendicular thereto, contiguously conforming to one another,said method including providing a die, used for casting the mirror segmented surface and constructing the die from a casting of a continuous surface of the desired shaped by cutting said casting, or a casting thereof, into smaType: GrantFiled: November 14, 1986Date of Patent: June 14, 1988Assignee: Roxor CorporationInventor: C.

Patent number: 4674850Abstract: In a transparent molded segmented mirror having individual sectors on a transparent molding and comprising a myriad of reflecting surfaces at the rear side of the mirror away from the viewer, said surfaces located to produce, in the eyes of the viewer, a virtual image, or separate virtual images from separate portions of such molded mirror, there being zones separating the reflecting surfaces, the improvement comprising:(a) a material coating said zones and which includes a light absorber,(b) such material having approximately, the same index of refraction as the transparent molding,(c) whereby undesirable reflections from said zone are substantially reduced, because light impinging thereon cannot be reflected, but is only absorbed.Type: GrantFiled: November 18, 1985Date of Patent: June 23, 1987Assignee: Roxor CorporationInventor: C.
