    • The duplicator comprises a housing with a carrier supporting first and second spaced platens alternately movable by the carrier to a light exposure station in the housing. Master microfiches to be duplicated are manually positioned on the platens such that when a master microfiche on the first platen is in the housing being exposed, a second master microfiche may be loaded on the second platen, preparatory to having a duplicate made. A foot pedal is provided to actuate movement of the platen carrier and also control a vacuum hold down system for the master microfiches positioned on the platens. A capstan driven by a geneva movement in the housing positions successive lengths of film from a film reel in the housing at the light exposure station for contact printing with the master microfiche on the platen positioned at the light exposure station. A pivoted pair of rollers exert a tension bias on film from the reel to the capstan to maintain it taut and also provide an arrangement whereby the resistance to pulling movement of the successive lengths of film by the capstan is always the same for each successive length independently of the amount of film on the supply reel in the housing.
    • 复印机包括具有载体的壳体,该载体支撑第一和第二间隔开的压板,其可由载体交替地移动到壳体中的曝光站。 要复制的主微缩胶片手动地定位在压板上,使得当第一压板上的主缩微胶片在壳体中被暴露时,可以将第二主缩微胶片装载在第二压板上,准备具有制备的副本。 提供脚踏板来致动压板架的运动,并且还控制用于位于压板上的主微缩胶片的真空压紧系统。 在壳体中由日内瓦运动驱动的绞盘从在曝光站处的壳体中的胶片卷轴定位连续长度的胶片,用于与位于曝光站的压板上的主缩微胶片进行接触印刷。 一对转动的辊子将胶片上的张力偏压从​​卷轴施加到绞盘上,以保持其拉紧,并且还提供一种布置,其中由主导轴对连续长度的膜的牵引运动的阻力对于每个连续长度独立地总是相同的 在外壳中的供带盘上的胶片量。

    • A purging system is provided for reducing and substantially eliminating contaminants, moisture, residual gas and the like from a work station such as, for example, a developer station in which ammonia gas is used for development of diazo type films. The system includes a check valve connected between one end of the developer station and a supply of compressed air, and a 3-way valve connected between the other end of the developer station and a supply of ammonia gas and an ammonia exhaust container. During development, the ammonia is passed into the developer station under a relatively high pressure and the flow of the ammonia is stopped by the check valve. After development, the pressure in the developer station is lowered thereby opening the check valve and causing flow of air from the supply of compressed air through the developer station, the 3-way valve, and into the exhaust container to thereby purge the entire system of contaminants, moisture and residual ammonia gas.

    • A dry-process method and apparatus for producing archival microform records from light reflecting hard copy utilize a dry-process mask film strip which is photosensitive to and microimaged by light reflected and reduced or condensed from the hard copy and developed by heat to provide microimaged transparencies therein as the mask film strip is moved to an imaging and developing station. It also utilizes a dry-process microform film which has archival properties and which is sensitive to and microimaged and developed by short pulses of electromagnetic energy above a threshold value applied thereto through the microimaged transparencies of the superimposed mask film strip when it is moved to an image transferring station to provide in the microform film imaged microform records which conform to the transparent microimages in the dry-process mask film strip and, hence, the hard copy and which have achival properties. The microform film is preferably in the form of a microfiche.
