A web of material is drawn by the machine from a removable supply roll over a first self-centering pulley, across a flat reviewing surface, over a second set of self-centering pulleys arranged in a figure S fashion, and is wound on a removable takeup shaft. Cutting means are provided for severing the portion of the web wound on the takeup shaft from the remainder of the web, and motor driven means are provided for selectively driving either the takeup shaft forwardly or the supply roll rearwardl...

The invention relates to a pulsed laser viewing system adapted to view range intervals in a scene by gating the detector signal; according to the invention, the viewing system also includes a switching device for repetitive interchange of the range interval viewed so that the image contrast of a viewed target may be repetitively alternated between positive and negative. The switching device may operate to interchange either the detector gating time periods or the detector signal channel. Alterna...

A viewing toy is provided which may be held by a user in front of his eyes. The toy has a plurality of transparent openings and, when the toy is rotated by the user's finger, a pleasant visual effect is obtained when viewing a visual target.

An instrument for the individual viewing of pictures disposed successively on a transparent film strip, with a housing in which a binocular viewing window and a lens system enlarging the viewing angle and located in the ray path between viewing window and object are provided, and with holding and guiding means holding the film strip in a viewing plane, wherein the beam paths or optical axes associated with the two viewing windows are brought together approximately in the center of a common pictu...

A laryngoscope curved blade includes a pair of fiber optic bundles, one fiber optic bundle adapted to transmit light to the distal end of the blade and the other fiber optic bundle adapted to provide a viewing channel for telescopic viewing of the area adjacent to the distal end of the blade. A lens attached to the proximal end of the blade gathers and focuses the light transmitted by the viewing channel fiber optic bundle. Additionally, a lamp located on the proximal end of the blade provides i...

Preferred forms of viewing apparatus according to the teachings of the present invention are shown as including an enclosed and elongated see-through passage having a hooded front opening. The rear end of the enclosed and elongated see-through passage includes a visually opaque annular perimeter portion extending around a rear opening of a size smaller than the front opening.

The front portion is generally arcuate, with straight top and rear portions joined by a further arcuate portion. The top portion inclines upward and rearward and support pillars are mounted on each top portion, spaced apart along the top portion. Seating members are mounted on the pillars and flooring members are...

The invention of this disclosure is a viewing head that packages a spherical mirror, beamsplitter, and cathode ray tube (CRT) in an enclosed container. The process of assembling the viewing head will automatically maintain the spherical mirror, beamsplitter, and CRT in optical alignment, making a time-consuming alignment procedure unnecessary. Because the optical equipment is contained within an enclosed container, the optical equipment will not have to be cleaned as often.
