Abstract: A toothbrush has an integral identification system for distinguishing one (1) toothbrush from another. At the bottom of the toothbrush handle is a cylinder and rotating thumb wheel assembly. The cylinder has a plurality of indicia which are visible one (1) at a time through a window on the side of the brush handle. A user rotates the thumb wheel to display an individual indicium. Once selected, a locking pin mechanism prevents the cylinder from being accidentally turned. These features allow multiple users to distinguish their toothbrush from another's by verifying the displayed indicia. Alternative embodiments can be retrofit and/or replaced on a toothbrush handle.

Abstract: A rolling information display apparatus and a method of displaying product information on a roller grill. A circular and symmetrical thimble device is configured to accept replaceable product information displays through the center of the device. The thimble acts as a collar for the product display information sign which is removable to allow for changing product information. The apparatus rolls along with the movement of the roller grill on which products are kept warmed in a typical retail display. The apparatus and the method of display disclosed allow for immediate labeling of products on a retail roller grill along with quick change capability to allow information to be changed in the thimble without the need to open up any apparatus or device.

Abstract: In one aspect, a rolling information display apparatus for use with a roller grill includes an elongated envelope. A cap is removably positioned over at least one opening of the envelope. An information bearing medium is removably positioned inside the envelope. In one embodiment, a sealing member is disposed to create a substantially watertight seal over at least one opening of the envelope. In another aspect, a rolling information display apparatus for use with a roller grill is a cylindrical rolling member having one or more rolling surfaces rolling in contact with heated rolling surfaces of the grill. The cylindrical rolling member also has one or more recessed surfaces bearing information about food items offered for sale on the grill. The recessed surfaces are provided in regions of the rolling member that are of diameter less than regions of the rolling member in which the rolling surfaces are provided.

Abstract: A display system includes a frame and a plurality of rotatable columns carried by the frame. Each of the plurality of rotatable columns may include a column connection member, at least one display engagement member carried by the column connection member, and a plurality of display members carried by the at least one display engagement member. The display system may also include a respective plurality of display guide members carried by the frame to engage each of the plurality of rotatable columns. Each of the respective plurality of display guide members may include an arcuate shaped guide. Each display guide member may have four imaginary quadrants and a portion of the arcuate shaped guide extends through each of the four imaginary quadrants. Each portion of the arcuate shaped guide extending through each of the imaginary quadrant preferably has a different shape.

Abstract: A display system may include a frame, column connection members connected to the frame, and column members rotatably connected to the column connection members. The display system may also include a magnetic drive assembly carried by the frame that engages the column connection members to selectively rotate the column members. The magnetic drive assembly may include a power source, energizing members connected to the power source, and column movement members connected to the column connection members. The energizing members may include an electromagnet, and the column movement members may be positioned spaced-apart from and overlying the energizing members. The electromagnet of the energizing members may be selectively energized to form a magnetic field between the energizing members and the column movement members to selectively cause rotation of the column members.

Abstract: A display system may include a frame, column connection members connected to the frame, and four-sided column members positioned adjacent one another and rotatably connected to the column connection members. Each column member may include a connector and elongate display members positioned adjacent one another and pivotally connected to the connector. The display system may also include a drive assembly carried by the frame that engages the column connection members to rotate each column member so that selective display members pivot in a predetermined direction during rotation to change the shape of the column members allowing rotation thereof when positioned adjacent one another.

Abstract: An information displayer with interchangeable boards for use in displaying advertising messages. Two sets of boards are disposed on two chains respectively, with each chain rotating about a pair of pinions. One pinion is stationary while the other is connected to a stepping motor. Hooks on a rigid bar grasp openings in the boards to release and display the boards. A pre-programmed microprocessor controls the stepping motor, permitting the boards to be displayed in any selected manner.

Abstract: A conductive paste in which cracks do not occur even at boundaries between areas of different film thicknesses comprises spherical and flake-form silver powders, a low softening point glass frit, organic rhodium material and an organic vehicle; the proportion of the flake-form silver powder with respect to the total amount of silver powder is in the range 15 to 80 wt % and the proportion of the rhodium contained in the organic rhodium material with respect to the total amount of silver powder is 0.0001 wt % or less.

Abstract: Two spaced apart, generally flat, outer members have a connector connecting them together at their centers. A third member having at least one segment portion connected thereto by resilient inwardly biasing members is positioned in the space between the outer members and has an inclined surface on at least one side thereof mating with a complimentary inclined surface on one of the outer members, whereby squeezing the outer members together at their perimeters adjacent the segment portion causes the segment portion to extend outwardly from the perimeters of the outer members and the connector, and to retract when the squeezing pressure is removed.
