	Foldable transparency enlarger for overhead projector - Patent 4728184
		Overhead projectors in general have a top surface with a glass plate through which light travels along an optical path to an overhead lens so that a transparency placed on the glass plate will be projected onto a remote screen.
		While the use of such self-made transparencies is clearly desirable, a problem is encountered in viewing these transparencies through a conventional overhead projector since the transparencies are only three inches by four inches and white light shows around the sides of the transparency when projected on a screen.
		Lens 32 ensures the proper focusing of the image of the transparency projector 1 on the lens proper, whereas the predetermined pivoting movement of the leg means as shown in FIG.
