Abstract: Greeting cards can be organized into multiple sender profiles. Greeting cards for each profile are displayed in one or more displays. The display can include one or more tiered display panels. Each tiered display panel can include multiple rows of pockets for displaying greeting cards in a full-facing or partial facing manner and captions at one or more of the pockets to display the internal content of the greeting cards. The display also can include a display panel identifying the sender profile associated with the apparatus. Each sender profile can be assigned a unique color which is applied to the display panel associated with the respective sender profile.

Abstract: A device for successively changing elongated flexible objects from an active viewable position to a non-active, non-viewable position includes a rotatable drum to which the flexible objects are attached, a motor driving the rotatable drum in opposing rotational directions, and a controller unit controlling motor speed and direction. A balancing spring is preloaded when the flexible objects are unwound from the drum, providing a lifting force when the flexible objects are wound up on the drum. By using a freewheeling clutch, preloading only occurs in one rotational direction, the balancing spring freewheeling in the other direction, taking no load. Utilizing a magnetically interactive identification strip the device gains highly accurate information on the position of the flexible elongated objects. By pre-attaching the flexible elongated objects on each other and providing the identification strip on the designated carrier flexible object exchanging the set of flexible elongated objects is made very simple.

Abstract: A rotary imaging device has a hollow body. A wall of the body is formed with a window. An interior of the body has a stopping piece protruding from the wall. An outer side of the rotary shaft is installed with a rotary shaft mounted within the body. A periphery of the rotary shaft has a plurality of sheets with figures being depicted or printed thereon. The rotary shaft is driven to rotate the sheets along a predetermined orientation; and outer ends of the sheets resist against the stopping piece so as to stop intermittently to present an effect as playing movies. Music machine center or chip can be added to the rotary imaging device so as to present image and music at the same time. Furthermore, a pen sharpener can be added to the rotary imaging device.

Abstract: Advertisement at the point of purchase is presented by a box containing a rotary device which displays graphic material on each step of the device. The rotary device is mounted in a box having a lens focused on the graphic material. A very low cost is achieved by a plastic plate shaped to form two cantilever springs, one of the cantilever springs has a tooth which steps the rotary drive into a viewing position, and the other of the cantilever springs has a tooth which stops the rotary device in a viewing position.

Abstract: A device for storage and display of photographs consisting of a housing with front frame and a spindle containing photo envelopes supported mid-way across the front frame. The spindle is formed in unique manner to carry a large plurality of photo envelopes by heat welding each envelope to the spindle in close spacing. Each envelope contains two photos back-to-back, and rotation, either manually or motor controlled, indexes intermittent display of the successive photos with two photos always in view in the frame.

Abstract: An improved photo display device of the type having a housing with frame and double photograph envelope providing dual photo viewing as presented within the frame, a first improvement consisting of an alternative picture rotating mechanism that includes both a manual ratcheting system on one side of the housing and a motor drive or automatic ratcheting system on the other side, and a second improvement that consists of a unitary housing/frame formation that receives a spindle assembly directly through the front frame which is then secured by side entry and snap-fit of right and left ratcheting knob assemblies.

Abstract: A teleindicator for information boards is described. The main characteristic of the teleindicator consists in comprising first means for the registration of input signals relating to an indication which has to be presented by the said teleindicator, second means adapted to process the signals from the said first means and to control third means which actuate, in a mechanical way, the display of the said indication by means of indicator elements.

Abstract: A leaf type indicating device provided with a synchronizing piece made of a spring material, rotatably mounted on a main shaft and having a side portion engageable with a lug formed on one leaf belonging to a first indicating leaf group having a large number of turns per unit time, a bent portion engageable with at least one leaf belonging to a second indicating leaf group arranged adjacently to the first indicating leaf group and having a small number of turns per unit time and an end portion inserted in a hole formed in a body frame and connected with the body frame in order to make the manufacture at a low cost possible.

Abstract: A rotary indicating device comprising a rotary drum supporting respectively rotatably a plurality of indicating plates, a ring-shaped spring fitted on one side surface of the rotary drum and resiliently pressing the respective rotary shaft portions of the plurality of indicating plates in a direction along the diameter of the rotary drum and a member for turning the plurality of indicating plates in turn with the rotation of the rotary drum so as to be able to be simply assembled and to stably hold the indicating plates in the indicating position.

Abstract: A picture display device includes an array of picture frames hinged together, as by an endless belt, in which the inner ends of the frame sections are attached to the endless belt. The frames radiate outwardly from the belt and are arrangeable in a pair of side-by-side packs in which the frames in each pack lie flat against each other, and in which the inner frame sections of one pack abut the inner frame sections of the other pack. A support is provided to hold the packs in side-by-side relation in a manner which permits advancement of and guides the frames from one pack to the next. The frames and the support are arranged so that advancement of a frame from the end of one pack to the beginning of the next pack causes all of the other frames in the array to advance an incremental amount. Means also are provided for biasing each of the frames in each pack flat against each other as well as to bias one of the packs against the other of the packs.
