Abstract: A film-engaging mechanism for incorporation in a camera which uses self-developing film has a receptacle for a film cassette and a processor for developing the film. The receptacle houses a replaceable film cassette, positions it to align the foremost film unit therein at the image surface of the camera, and advances each film unit for transport to the processor. The processor is aligned to receive each film unit advanced out of the receptacle, and subjects it to the critical operations that assure proper photographic development. The film-engaging mechanism thus brings together, in a single, readily-mounted assembly, the camera structure necessary for engaging a self-developing film unit in a camera to ensure proper photographic treatment, but leaves the design, construction and fabrication of the camera otherwise free of the film-engaging requirements.

Abstract: This disclosure depicts method and apparatus for screening slot-mask, stripe screen type color cathode ray tubes particularly method and apparatus for improving screen stripe uniformity and edge definition. The method involves supporting a curved, approximately rectangular faceplate which has on its concave inner surface a photosensitive coating and which has supported adjacent its inner surface an exposure mask defining an array of columns of spaced slots oriented parallel to the minor axis of the faceplate. A line source of radiation actinic to said coating is supported on or near a central axis of the faceplate. The disclosed method includes producing a virtual image of the line source which appears, when viewed from off-axis points on the faceplate, to be rotated in a direction effective to decrease an unwanted rotational displacement of the mask slot images induced by the relative geometry of the line source, the mask slots and the faceplate inner surface.

Abstract: The method of this invention is utilized by the manufacturer of a camera apparatus of the type having an automatic shutter latch mechanism, as well as an automatic film advancement mechanism to adjust the control system of the camera apparatus prior to the shipment so that even if the shutter latch mechanism is accidentally unlatched, the user will still be able to insert a film cassette into the film receiving chamber without incurring an automatic film advancement operation prior to closing the film loading access door. The method provides for the advancement of the camera control system through a portion of its photographic cycle by an external motor to a point in the cycle where a film unit would have otherwise been processed and advanced from the camera thereby insuring that the first time insertion of the film cassette within the camera by a user will not result in a film advancement operation if the automatic shutter latch mechanism should become unlatched during transit.
