Abstract: A reflecting system utilizing a uniquely designed external mirror of specified shape to project and reflect light beams, distortion-free to the eye, from a light source to a receiving surface. The light source is uniquely positioned in relation to the mirror and supplemental mirrors may also be utilized to afford flexibility in the positioning of the elements. A uniquely designed reflector is constructed of a plurality of points specifically determined by an iterative method of solution utilizing as critical variables the size of the viewing surface, the distance from the light source to the reflector and the distance from the reflector to the receiving surface.
Abstract: A screen for a projection system supported by a pair of cross members extending to the four corners of the screen where they receive a tensioning member disposed around the perimeter of the screen and held in stress by a tensioning mechanism secured to a portion of one of the cross members. The cross members may be secured in their "up" position by means of a restraining member and the screen may be tilted forward as permitted by one of several modes of support. The screen may be shaped with curvilinear edges preferably of a catenary configuration to increase tautness which is imparted thereto by the tensioning member.
Abstract: A projector case assembly designed for use with a projector system which utilizes a system of mirrors to provide enlarged panoramic viewing. The projector case assembly is designed to accommodate any standard movie or slide projector and it serves as both support means during the time of actual projection and as a storage means when the equipment is not in use.
