Abstract: A concentric rotating disc assembly includes a pair of outer discs and an intermediate disc. The intermediate disc rotates about a journal which is die cut from the center of the intermediate disc with each face of the journal adhesively secured to an inner face of an abutting outer disc. The assembly is fabricated from a rectangular paperboard blank having parallel fold lines which divide the blank into three square panels. Score lines are provided in each panel to define its respective disc and a central circular score line in the intermediate panel defines the periphery of the journal. When the panels of the blank are folded along their fold lines in a predetermined order, the panel carrying the intermediate disc is positioned between the panels carrying the outer discs and all discs are concentrically registered.

Abstract: A low cost smokeless ashtray includes an upper, generally cylindrical receptacle having a bottom panel with a pair of selectively closeable apertures. Extending downwardly from the center of the bottom panel is a unitary journal having a radially projecting key. The receptacle is rotatably mounted to a base with the journal extending through a keyed orifice. The base includes an upper planar bearing plate having a pair of butt receiving wells. The wells are accessed by rotating the receptacle relative to the base until the bottom panel apertures are registered with the wells. The receptacle and base are each preferably molded in one piece construction of a suitable thermosetting polymer such as an amino resin, for example, a melamine molding compound with an alpha cellulose filler.

Abstract: A suspended sign display includes rigid front and rear leaves hinged together adjacent their upper edges. The rear leaf includes a device for attachment to a supporting surface such as a store window. The leaves are held folded together by a magnet which is secured to the inner face of each leaf. An indicia bearing placard sign is clamped between the magnets. An abutment projects from the rear leaf to assist in positioning the placard. The outer face of the front leaf includes additional sign indicia either directly imprinted on the leaf or on a card carried by the leaf, and the outer face of the rear leaf may also include sign indicia. In one embodiment, each leaf is a separate extrusion having a grooved channel along its upper edge. A separate hinge extrusion is engaged in each of the channels. In an alternate embodiment the mount is formed as a single extrusion, and the device for attaching the mount to a supporting surface includes a pair of diverging webs which clip to a shelf edge molding.
