US Classification:

46 74D

Abstract:

A high utility disk toy for use in a multitude of indoor and outdoor games, comprising of a disk hull with a concave/convex surface with a central crown and dome and a peripheral horizontal rim wing flight stabilizer that extends outwardly from the base of the disk hull. In one embodiment of the invention the toy is molded or formed so that the three major parts, the disk hull, central crown and dome and the rim wing flight stabilizer are of a single piece construction with the same lightweight material. In an alternative embodiment of the invention the three major parts are made separately of the same or different materials in various shapes, sizes and colors. Said parts are then assembled by the users, to achieve desired results or to study and observe the effect of a part change on the spin or flight characteristics of a given unit. The new high utility disk toy can be placed on the tip of the finger and spun as a spinner or it can be inverted with the dome down and spun like a top on a smooth surface or it can be thrown and caught as a single unit or it can nest into or onto another or more of like design and can be thrown as a plurality of units that will separate in flight and fly the full flight in formation to the target area to be caught by one or a plurality of participants.

Abstract:

In a color-slide duplicator having a housing containing a light source which illuminates an opening in a housing wall, and a support for a camera above the housing for photographic reproduction of a slide to be duplicated; an assembly for supporting the slide comprises a carrier plate releasably and adjustably secured by magnets to the housing wall so as to span the illuminated opening which registers, at least in part, with an aperture in the carrier plate, and first and second parallel guide bars having undercut, beveled edges facing toward each other and being arranged on the carrier plate at opposite sides of the aperture in the latter, with one of the guide bars being movable laterally and resiliently urged in the direction toward the other guide bar, such guide bars being included in a quick-release mechanism by which the slide to be duplicated is positioned and held against the carrier plate over the aperture therein. In the case of a slide having a rigid frame, opposing side edges of the frame can be directly engaged by the beveled guide bar edges. When the slide is an unmounted flexible film, a bearing and masking plate with an aperture registering, at least in part, with the carrier plate aperture is engaged, at opposing side edges, by the beveled guide bar edges to be urged thereby against the carrier plate with the flexible film held flat between the carrier and bearing plates.
