    摘要: A telescope body is disclosed. The telescope body generally includes a primary structure for holding a mirror, a secondary structure for holding a means for receiving a reflection from the mirror, and a mounting section connecting the primary and secondary structure. The primary and secondary structures include four-bar linkages which have linkage action planes intersecting at the focal point of the mirror. Apparatus for preventing the secondary structure from intruding in a raypath of light to the means for receiving a reflection is also disclosed.

    摘要: Apparatus for processing individual rolls of an exposed composite self-developing type transparency film structure. The composite film structure includes first and second sheets which are adapted to be located in superposed relation prior to having a processing liquid spread therebetween to initiate the formation of a visible image within the composite structure. The apparatus includes a first pair of rollers for withdrawing the first sheet and a portion of the second sheet from a film cassette, and a second pair of rollers which are adapted to advance the first and second sheets, in superposition, into a dark chamber while simultaneously spreading a processing liquid between and in contact with the sheets so as to initiate formation of the visible image in the composite film structure.
