Abstract: A device including a pair of superimposed pliable sheets that are interconnected or sealed along peripheral edges. The device includes an enclosed, liquid-containing inner chamber defined by the sealed peripheral edges and by the pair of superimposed pliable sheets. The liquid is freely movable within the chamber. At least one discrete article is suspended within the liquid, and the article is manipulatable by causing displacement of the liquid medium. Graphics are included on one of the sheets. These graphics correspond in shape to the discrete article, and that discrete article is alignable with these graphics.

Abstract: This invention pertains to a retractable roller-hinge assembly for use with retractable overhead doors. More particularly, this invention relates to a novel roller-hinge assembly which when installed on conventional retractable overhead doors, such as garage doors warehouse doors or truck doors, enables the door panels to pull away more quickly from the door frame as the overhead door is raised, or lowered. A hinge assembly for connecting upper and lower panels of a retractable overhead door comprising: (a) upper devices for securing to the upper panel; (b) lower devices adapted for securing to the lower panel, the lower devices being hingedly connected by a pivotal axis to the upper devices; (c) roller and roller axle devices rotatably connected to the upper devices, said roller and axle devices being adapted to move towards the lower devices as the upper devices are pivoted about the pivotal axis.

Abstract: An article of manufacture, comprising a pair of superimposed pliable sheets. The sheets are interconnected along at least their peripheral edges. A liquid-containing chamber is provided at the center of the article, and this chamber is formed with the pair of superimposed, pliable sheets. A generally flat figurine within the chamber floats within the liquid, and a point of the figurine is secured to at least one of the pliable sheets to enable the figurine to float securely within and pivot about in the liquid.

Abstract: A protective serving mat is disclosed comprising generally flat first and second chambers superimposed on each other. The first chamber is transparent and is adapted to embody fluid media and objects suspended therein for amusement. The first chamber includes a resealable opening so that a user may access the first chamber to alter the contents as desired. The second chamber is visible through the first chamber and is used to protect and display generally flat items such as papers with sealing decorative or amusing indicia or menus. The second chamber includes an opening to allow access to the chamber so that the menus or indicia bearing papers can be varied as desired by a user.

Abstract: The present invention is an article of manufacture comprising an inner surface, an outer, generally visually transparent surface, and a generally annular space between and defined by the inner and outer surfaces. The annular space contains a liquid. One or more generally flat disks are provided within the annular space, and the disk or disks floats upon the liquid. A plurality of fins within the annular space imparts turbulence to the liquid and propels the disks as the article is rotated about its axis.

Abstract: A serving mat includes a pair of superimposed sheets sealed to each other to define a chamber having a free-flowing liquid medium therein with a plurality of discrete articles suspended in said liquid medium and movable by manipulation of the liquid medium in the chamber.
