Abstract: A hand held electrically driven cutter assembly for removing casts from the body of a patient includes a vertically articulatable bottom plate insertable between the cast and the body surface which on the interior of the cutter assembly forms a switch in series with a trigger switch connected to the main power. Two circular cutters, inclined relative each other, are disposed above and ahead of the bottom plate to open up a kerf therefor. The power to the cutters is transmitted through a pulley and gear combination to be driven by an electric motor. It is this electric motor that is series connected to the bottom plate switch and power will be applied to the cutters only upon upward urging of the cutter assembly.

Abstract: A power driven shaver of the type that includes a housing that has a prime mover therein, with one end of the housing supporting a transverse thin curved shield. The shield has a number of longitudinally and circumferentially spaced slots therein that are of such dimension that whiskers may extend therethrough. A number of helical shaped blades are rotated by the prime mover in close proximity to the interior surface of the shield, with the blades serving to sever inwardly projecting portions of the whisker by a rotating slicing action. The present power driven shaver is free of vibration, and exerts no uncomfortable pulling action on whiskers as they are severed, or the whiskers as they are cut are not compressed or pinched.

Abstract: A device for use in maintaining that portion of a poster between upper and lower edge portions thereof in a flat configuration. First and second rigid frame piece assemblies removably engage upper and lower horizontal edge portions of the poster and are disposed to the rear thereof. First end portions of first and second elongate members engage the first and second frame assemblies with the elongate members situated to the rear of the poster, and with the elongate members being of sufficient length that the second end portions thereof overlap. The overlapping second end portions are frictionally and adjustably engaged by holding means to permit the device to be moved from a first to a second position, and when the poster device is in the second position, that portion thereof between the first and second end portions is slightly tensioned and disposed in a flat configuration whereby the poster and the device may be suspended from a wall by a conventional picture hanger.

Abstract: A table tennis assembly including a table having a flat upper surface, a transversely disposed net that divides the surface into two playing areas, a ball, and a pair of paddles that include ball striking surface that is characterized by at least the periphery of the flat upper surface, the net, the ball and the striking surfaces of the paddles having a fluorescent material thereon. The fluorescent material is selected from a group that comprises organic compounds, dyes, and inorganic compounds that emit light visible to the human eye when exposed to electromagnetic radiation in the infra-red or ultra-violet range. When the assembly that includes the fluorescent material is exposed to radiation to which the fluorescent material is responsive, the table, net, ball and paddles are illuminated to the extent that table tennis may be played in the dark.
