Abstract: An apparatus for creating a water disk effect without water. The apparatus includes first and second disks, each having a first side with a substantially planar surface and a second side with a surface textured with a three dimensional (3D) pattern or topography including raised, arcuate ridges in a whirlpool or spiral arrangement. The apparatus includes a housing that supports the first and second disks for independent rotation about a common axis. The disks are positioned such that the first sides are proximate but spaced apart to avoid contact, such that the 3D patterns face outward toward viewers of the apparatus. The apparatus includes a drive assembly rotating the first disk in a first direction and concurrently rotating the second disk in a second direction opposite the first direction. A water disk effect is created during counter rotation when light from the Sun or other source strikes the disks.

Abstract: An automatic rotating decoration includes a rotating body, a support, a driving device connecting the support, and a transmission member connecting the driving device and the rotating body. The support, the driving device and the transmission member all are received in the rotating body. An opening is defined in the rotating body. The support is exposed to the opening. The driving device includes a driving body and an output shaft extending from the driving body. The driving body includes a motor body and a battery seat electrically connecting the motor body. The automatic rotating decoration of the present invention may automatically rotate around the support on another object without additional housing thereby simplifying the structure of the automatic rotating decoration, increasing fun of the automatic rotating decoration and facilitating the handling.

Abstract: A tension fabric display structure incorporates segmented tubular framework permitting easy on-site assembly and disassembly and includes an integral drive motor coupled to a drive shaft that is supported for rotation within a framework tube. Each one of a plurality of attraction elements suspended from the framework tube housing the drive shaft is rotationally driven by a coupling assembly connected to the drive shaft.

Abstract: A circular sealed panel 1 includes transparent walls 10-13 separated by spacer rings 14-16 to form intervening sealed chambers 18-20. The chambers are filled with different colored translucent liquids leaving colorless air spaces in each chamber. The panel is supported on friction rollers 2 and 3, one of which is driven by a motor to rotate the panel. The spacer rings 14-16 are formed with cup-like recesses 32 which collect air from the top of each chamber and release it towards the bottom of the chamber so that colorless volumes of air continuously travel upwardly through the chambers thereby presenting continuously moving shapes and color combinations to an observer looking through the panel.

Abstract: The present invention comprises of an enclosure with an opening wherein a 3-dimentional translucent picture is attached to said opening. Multiple pieces of polarized film are attached behind various portions of the 3-dimentional translucent picture. The enclosure contains a light source, a polarized film, and means for moving said polarized film within the enclosure. The 3-dimentional translucent picture will appear to have motion when the polarized film is moved relative to the pieces of polarized film attached behind the 3-dimentional translucent picture.

Abstract: A visual display device for providing a continuous, non-reversing animated sequence of displayed images to an observer with a separation member; a plurality of interposed coded images fixed to a first surface of the separation member to form an image member; a plurality of shutter elements fixed to the second surface of the separation member, and a plurality of viewing elements interposed between the plurality of shutter elements to form a shutter member. The coded images, the plurality of shutter elements, and the plurality of viewing elements can share a common orientation and a given pitch. The image member may be transparent except for the plurality of coded images. A strand of flexible material may be provided for suspending the visual display device for continuous rotation.

Abstract: An apparatus for the formation of a visual sense effect comprises a first object A having a plurality of windows disposed around an axis of rotation C and a second object B so disposed as to show part thereof through the windows W of the first object A, with the first object A and the second object B adapted to be rotated relative to each other round the axis of rotation C. By virtue of the visual sense effect in vision, this apparatus allows an object of a polygonal shape to be perceived as though the object were repeating enlargement, contraction, deformation, and eccentric movement.

Abstract: A traffic control device has a base (14) and a sign (16) rotatably carried by the base. The sign has at least two sides, one of which bears a "GO" indication and the other a "STOP" indication. A radio control means (11) causes a motor in the base to position the sign with the "GO" and "STOP" sides alternately in substantially the same angular position relative to the base.

Abstract: A display device consisting of a plurality of rotating segments each carrying elements of a message or sign, each rotating relative to each other, the center of rotation of each being contained within the circumference of its adjacent segment, either eccentrically or concentrically. These segments are driven by a series of planetary gear systems or their equivalent, arranged in layers, each driving the next. To these segments may be attached a plurality of auxiliary devices, all driven by the same mechanism, which can enhance the attraction of the device, carry elements of the message, etc. Each segment or auxiliary device can be of a variety of shapes, colors, graphics, etc. Segments can be nested or overlapping, totally or in combination. Message can be continuously or intermittently scrambled and unscrambled.

Abstract: A traffic control signal particularly adapted for alternate one-way traffic situations such as are frequently encountered in highway construction zones whereby `STOP` AND "SLOW" sign panels can be alternately displayed with suitable control mechanism which produces a combination rotational and axial displacement of a signal panel whereby one traffic control message can be superimposed upon another for displaying either a "STOP" message or a "SLOW" for the vehicular traffic.

Abstract: A point-of-purchase display assembly or signage includes gear discs which rotate about parallel axes and have light transforming material disposed on their outer faces. The discs are rotated (at about 10-20 rpm) to continuously change the visual perception by an observer of the light transforming material. The light transforming material may be holographic or diffraction material, or patterned metallized foil. Modules of the gears are mounted in a linear support, or in channels in a bar or plate, and are covered by a lens. Alternatively, a number of gears/discs may be connected together by chain links. All of the elements are preferably of plastic.

Abstract: A computer-controlled coin parking meter for managing the use of a parking lot having up to about ten parking spaces. It includes a first display device which singularly identifies the parking places and push button switches for operating it; a second display device indicating the parking time bought for the identified space; a rotary disk having, along its periphery, visible indicia indicating whether or not parking time has been paid for the parking places and a step-motor for rotating the disk so as to provide this latter information. The meter further includes a coin receiving and counting machine capable of allowing operation of the second display device so that it indicates the parking time bought and also capable of allowing rotation of the step motor and therefore of the indicia disk to display the information.

Abstract: The present invention relates to an improved solar powered sign including one or more solar panels used to charge batteries which power various components of the sign. The sign may include a rotary display which is electrically powered and may also include a lamp. The sign may be mounted on a base facilitating easy transport.
