摘要： Photographic apparatus and process employing an applicator body disposed in communication with a container of processing liquid and adapted for conduction of the liquid to a surface of the body which is pressed into contact with the photosensitive area of an exposed sheet of photographic material. The applicator body is of filter material which upon contact with the liquid is pervious to the liquid and impervious to gas within a given range of pressure differential such that upon application of a suitable pressure to the source, gas-free liquid is conducted to the applicator surface and uniformly distributed thereat. Preferably, the container of the source of liquid and the applicator body are provided in a disposable assembly adapted for releasable mounting on a camera, and the container includes a plurality of deformable areas which may be selectively activated for repetitive application of a differential pressure to the applicator body in accordance with processing of successive film sheets. Additionally, a movable member mounted within the camera, for pressing of each film sheet into contact with the applicator body, includes a resilient non-planar surface having a raised surface portion configured for displacement of air from between the photographic material and the applicator as the photographic material is pressed thereagainst.

摘要： A lens mounting and securing apparatus in the form of a resilient retaining ring fits over a portion of a lens housing to secure the lens assembly to the shutter housing of a photographic camera. The resilient retaining ring is configured with a plurality of inwardly extending tab members which allow a portion of the lens housing to pass through the retaining ring in one direction while preventing any movement in the opposite direction to thereby fixedly secure the lens housing to the shutter housing. Additionally, the retaining ring is provided with a plurality of tab members for proper positioning of the retaining ring.
