  • Publication number: 20080301984
    Abstract: A method and apparatus for card viewing used to select desired layered compound images is disclosed. The device includes viewing windows, slots, and various card types. The cards, each of which may contain an element of the compound image to be formed are inserted into the slots in a prescribed manner such that layered combinations may be viewed through viewing panes. Some embodiments may include a background card to place the layered combination in context, or, by excluding the background card, the compound image may be placed against a desired background such that a portion of the background remains visible with the compound image superimposed thereon. In one embodiment, the method and apparatus may be used to select art frame and mat design combinations in connection with representations of works of art and desired backgrounds.

  • Patent number: 4856215
    Abstract: A device useful in sorting slides can be constructed so as to include a tray formed of a white polymer material and so as to include a plurality of slide holders pivotally mounted on the tray generally above the bottom of it so that they may be rotated between storage positions in which slides held by the holders are generally parallel to the bottom of the tray and adjacent to the bottom of the tray to a sorting position in which slides held by the holders are located at an angle to the bottom of the tray. Detents are provided for temporarily positioning the holders in the sorting positions. When they are held at an angle to the bottom of the tray slides held by the holders can be viewed as they are illuminated by ambient light. Because of the manner in which the slides are held they may be arranged in any desired manner by moving them to various position in the holders as they are illuminated.

  • Patent number: 4685231
    Abstract: The viewer includes a main body defining a horizontal opening within which a photographic disc is rotatably supported. A light source below the horizontal opening projects the viewed image onto a magnifier lens located above the opening. A viewing port renders the image identifying number on the disc visible. A switch control automatically closes a switch upon grasping of the handgrip portion of the main body. The control is inherently biased to a switch opening position.

  • Patent number: 4648189
    Abstract: An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a plastic core panel having light-transmitting properties, one face of the panel having formed thereon a metallized layer functioning as a double-faced mirror. Mounted on the layer and on the other face of the panel, respectively, are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of the panel are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the panel and is reflected by the convex terminations and by the inner face of the mirror to provide multiple internal reflection, causing the light to illuminate the front transparency to enhance its readability.

  • Patent number: 4531317
    Abstract: A portable apparatus for simultaneously viewing a transparency and a reflection copy image. The apparatus preferably complies with American National Standard Institute standards "Direct Viewing of Photographic Color Transparencies" and "Viewing Conditions for the Appraisal of Color Quality and Color Uniformity in the Graphic Arts." The apparatus includes a case which opens to have a cover portion positioned approximately horizontally near the top of an approximately vertical body portion. Pivotal side light shield plates can be opened to shield the sides of the apparatus from undesired ambient light, and a pivotal bottom plate can be positioned approximately horizontally for viewing prints. A transparency viewing plate having back lighting means for illuminating a transparency is positioned within the field of light from a source in the cover portion which strikes both the transparency and simultaneously the reflection copy image on the approximately horizontal plate.

  • Patent number: 4389803
    Abstract: A slide viewer or projector is provided with a device for preventing two or more slides from attempting to enter into the viewing or projecting area simultaneously. The device comprises a barrier with a wiper pivotally mounted thereon. The barrier and wiper are spaced apart from the path taken by a slide so that the slide pivots the wiper against the action of biasing means and then the barrier is raised into engagement with the upper surface of the slide and this allows the wiper to wipe over the upper surface of the slide to "kick off" any other slide resting on the surface.

  • Patent number: 4382664
    Abstract: Apparatus is disclosed for viewing photographic slides carried in a long magazine by a slide projector which is configured to accept only a circular slide magazine or carrousel. This invention provides a simple and efficient mechanism for using long magazines with a circular magazine projector without the need of first transferring by hand all of the slides from the long magazine into a circular magazine. An attachment adapted to be fastened to the projector housing has a covered channel for accepting and advancing a long magazine inserted therein. Adjacent the long magazine within the attachment is an intermediate storage tray which contains slide compartments and which is moved synchronously with the long magazine. Slanting guide rails extend from the long magazine to the intermediate storage tray, and these rails individually transfer the slides from the long magazine into the storage tray as the long magazine is advanced.
