Abstract: The compact view scope enables an observer to view miniaturized textual and pictorial images mounted in the scope. The compact view scope includes axially co-extensive outer and inner cylindrical bodies. The interior of the inner cylindrical body is hollow and is light transmissive. A first seal is established between the inner and outer cylindrical bodies by complementary thread members. The first axial end of the inner body defines an integral light filter end cap having at least one surface channel thereon. In a preferred embodiment, the surface channel has a U-shaped cross-section and provides a thinned end piece region which filters light therethrough. A film carrying miniaturized textual and pictorial images is disposed at the first axial end in the hollow, light transmissive interior of the inner cylindrical body adjacent the axially inboard side of the light filtering end cap. At the other, second axial end of the inner cylindrical body, a first lens chamfer is formed.

Abstract: A navigation device is disclosed, having a lens across an opening at one end of a case, and a compass across an opening at the opposite end of the case. A transparency holder is positioned between the lens and the compass, adapted to receive a map transparency with magnetic north thereon aligning with a north marking on the body of the compass, at a distance from the lens approximating the focal length of the lens. A grid wheel is provided between the transparency holder and the compass, having a transparent or translucent central area inscribed with parallel grid lines and at least one first directional arrow aligned parallel to the grid lines, the grid wheel being in close proximity to the transparency holder such that it is also at a distance from the lens approximating the focal length of the lens.

Abstract: An apparatus for viewing a representation of the celestial vault including a tube bearing a ring of graduations that indicate the dates of the days of a year, and a tube bearing a ring of graduations that indicate the hours of a day. The tubes are axially aligned and rotatable with respect to each other about the axis. One tube contains a representation of the night sky, and the other contains an element, such as a lens, for viewing the representation. The tubes are separably joined so that they can be disassembled, each tube rotated end-over-end through 180.degree., and the tubes reassembled. In one condition of assembly, a sky representation of the northern hemisphere is used, and in the other condition of assembly, a sky representation of the southern hemisphere is used.

Abstract: In one embodiment, the medical pendant includes a hollow center, elongated plastic housing with two opposing open ends. The housing is made of a material that is translucent and diffuse light into the housing's interior. A magnifying glass is sealingly mounted in the interior of the housing at one end thereof. A film retainer is removably mounted at the other end of the housing opposite the magnifying lens. The film retainer is made of a material that is also translucent to light and diffuses light into the interior of the housing. The medical or physical information is carried on a diazo film having a solid color background with light transmissive characters depicting the information. The film is mounted on an inboard surface of the film retainer. More particularly, the diazo film has a solid blue background with transparent characters.

Abstract: The viewer is constituted by a monolithic housing in plastic material, presenting a window with side guides and an external slot for inserting the slides, said window separating a chamber closed by a lens, from a receptacle containing a source of light and its supply means.According to the invention, the supply and lighting means are re-grouped inside a removable unit, which can be extracted from the receptacle housing it and in which it is connected; said receptacle comprising opposite the lens, a reflecting surface inclined to form an angle of about 45.degree. with the optical axis.

Abstract: A device is adapted for viewing transparencies disposed circumferentially on a disk. It comprises a case (10) adapted to contain a disk (12). A pin (15) is adapted to mount the disk (12) for rotation within the case (10). The disk (12) may be driven in rotation by virtue of at least one peripheral opening (10F, 10G) in the case (10). A pair of windows (10C, 10D) are disposed in face to face relationship and so that the transparencies (13) can move between them. A front member (11B) on one side of the windows is adapted to support an optical system comprising at least one lens (15) in line with and spaced from the windows. A rear member (11C) is adapted to constitute a shank for clipping the device to an article of clothing. The device may be used and worn as a badge, since the front surface of the case (10) may carry any form of inscription or illustration.

Abstract: A hand held microfilm reader wherein the film is maintained within the reader housing and the controls for positioning the film are easily manipulated by one hand. An optical system provides an intense automatically focused image projected onto a screen for viewing by the user. The light source is a conventional lens end bulb that has been rendered uniformly directional by its having been mounted in pre-aligned relationship with respect to a clip which is configured to be precisely registered with remaining portions of the optical system.

Abstract: A pendant type capsule is provided to be worn on the person as jewelry and having within an air and water-tight cavity therewithin a small microfilm containing the medical history or medical and personal characteristics of the person carrying or wearing the jewerly together with a suitable light sensitive backing for or adjacent to the film to provide lighting characteristics, and a lens at the other end of the cavity, with the film and lens fixedly mounted to provide fixed focus for observing the medical history of the person without the necessity of using other devices.

Abstract: A portable microfilm viewer for viewing a microfilm contained in a cassette. The viewer includes a housing with a lens system mounted therein. The cassette is removably received on a film transport mechanism which both supports and drives the film. A source of rotary motion is fixedly mounted on the housing and a bidirectional engaging device couples the rotary output to the film transport means for selectively transporting the film of the cassette in either of two directions across the lens system. The source of rotary motion can be a manual wheel or a motor device. A counter can be included for determining the film frame being viewed and for setting a desired film frame to be viewed, whereby the device will automatically stop when the desired film frame is in view. In an embodiment of the invention the microfilm viewer can also accommodate microfiche cards which can be viewed through the same lens system.

Abstract: A supporting frame with a handle has a transparent supporting plate mounted therein. The plate supports a thin transparency over the exposed surface of the plate. The transparency has a multiplicity of demagnifying fresnel lenses formed therein in abutting relation and in vertical and horizontal rows. The lens areas are rectangular in outline with very fine and closely spaced concentric light refracting grooves formed in one surface of the transparency and extending to the edges of the several areas. The frame has retaining shoulders therearound for removably holding one of several different opaque silhouette cards of different household furnishing articles, which are provided, along one edge of the frame.

Abstract: A plastic microfiche carrier has a central clearance for enabling an insertion of a replaceable microfiche film in the carrier. The corners of the carrier are tapered to facilitate an alignment of the carrier, and therefore the microfiche in a library file housed within the cartridge. The front or leading edge of the carrier is concave in the width dimension with a bullet-like nose double taper in the thickness dimension to guide and direct the microfiche, as it slips into and out of the library file.
