A cap assembly is provided for use with a container for storing and supplying aqueous ammonia to a diazo type copying machine. The cap assembly comprises a closure member mounted on the container and a key device associated with free ends of an ammonia feed tube and a drain tube connecting the container to a developer system of the copying machine. The closure member includes a feed outlet to permit ammonia flow from the container to the feed tube and a drain outlet to permit ammonia flow from the drain tube to the container. The closure member also includes a seal adapted for selective actuation by the key device between a first position for closing the feed and the drain outlets to prevent ammonia flow and a second position for opening the outlets to permit ammonia flow. The key device is releasably retained by the closure member when the seal is in the second position and is released from the closure member when the seal is in the first position, to thereby prevent escape of ammonia fumes from the container to the ambient atmosphere during replacement of an empty container with a container providing a fresh supply of ammonia. The key device also includes a lock actuable between a locked position to prevent movement of the key device and actuation of the seal between the first and the second positions, and an unlocked position to permit movement of the key device.

An optical device for a micro-image viewer or a micro-image viewer-printer machine receives a projected image of an illuminated micro-image, adjusts the spatial disposition of the projected image in an image plane and transmits the adjusted projected image to a viewing screen for viewing or to an exposure station for reproduction purposes. The optical device, in a preferred embodiment, includes a pechan prism positioned in a micro-image viewer-printer machine for receiving a projected image from a projection lens assembly. The pechan prism is rotatable about the illumination path or optical axis of the viewer-printer machine to enable the spatial disposition of the projected image to be rotated at least from 0 degrees to 180 degrees in an image plane. The pechan prism is mounted in the optical axis of the viewer-printer machine by a novel mounting assembly that enables both the controllable rotational movement of the pechan prism about the optical axis and the controllable longitudinal movement of the pechan prism along the optical axis. Additionally, the novel mounting assembly enables the pivotal movement of the pechan prism into and out of the optical axis to provide access to the projection lens assembly for the adjustment, repair, removal and replacement of the projection lens assembly.

Optical device

A self-priming pump is provided for metering a positive controlled amount of a volatile liquid to a utilization device. The pump comprises a piston means for pumping the liquid from a liquid supply container to a chamber, and from the chamber to a reservoir where the liquid is maintained at a uniform and constant level by an overflow port which drains any excess liquid back to the liquid supply container. The liquid remaining in the reservoir flows through an outlet passage to a well from which the liquid is dispensed in metered units under control of an adjustable needle valve. The needle valve is provided for controlling the rate of feed of the liquid to the utilization device, and is accessible for adjusting the liquid flow while the pump is in operation. The reservoir is also provided with vent means to prevent impediment of liquid flow and, also, to permit liquid flow immediately in response to initial start-up and operation of the pump.

The pechan prism is rotatable about the illumination path or optical axis of the viewer-printer machine to enable the spatial disposition of the projected image to be rotated at least from 0.degree. to 180.degree. in an image plane. The pechan prism is mounted in the optical axis of the viewer-printer machine by a novel mounting assembly that enables both the conrollable rotational movement of the pechan prism about the optical axis and the controllable longitudinal movement of the pechan prism along the optical axis. Additionally, the novel mounting assembly enables the pivotal movement of the pechan prism into and out of the optical axis to provide access to the projection lens assembly for the adjustment, repair, removal and replacement of the projection lens assembly.

An exposure system for a microfiche duplicating machine includes a mercury vapor light source and a light transparent platen disposed above the light source for supporting an original microfiche card and a duplicating film card for exposure by the light source. A shutter mechanism is interposed between the light source and the transparent platen to control the exposure of the duplicating film card, and a cover is disposed over the transparent platen to prevent the escape of light from the duplicating machine during the exposure. A mechanical linkage is provided for automatically opening a pair of shutters within the shutter mechanism upon the closing of the cover to initiate the exposure of the duplicating film card. Simultaneously, a timer is energized by the closing of the cover to initiate an exposure timing sequence. Upon completion of the timing sequence, a timer energized by a solenoid actuator releases the cover, and the shutters are automatically closed by the mechanical linkage to terminate the exposure.
