Abstract: Long wearing and reusable lithographic printing members are prepared from a zirconium metal or alloy that has an anodized zirconium metal or alloy printing surface. In use, the anodized printing surface of the printing member is imagewise exposed to electromagnetic radiation which transforms it from a hydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. Such inked areas can then be used to transfer an image to a suitable receiving material in lithographic printing. These printing members are directly laser-imageable as well as image erasable.

Abstract: Photographic film loading method and apparatus and a camera frame assembly having an internally baffled supply chamber. In the method, a guide is interposed in the chamber and a leading portion of the filmstrip is transported into the chamber. The filmstrip is then coiled within the chamber, between the guide and the baffle to form a film roll. During the coiling, an internal diameter of the film roll is maintained constant. The guide is withdrawn and the baffle is retained within the chamber with the film roll.

Abstract: An electronic camera includes a low resolution image sensor responsive to image light for generating a low resolution output signal that is used for camera control functions, such as image viewing, and a high resolution image sensor responsive to image light for generating a high resolution output signal that is used to produce an output image signal. The camera further includes an electronic display driven by the output signal from the low resolution image sensor, a zoom lens for varying the size of the image incident upon the high resolution image sensor and a zoom interpolator responsive to a zoom setting of the zoom lens. The output signal from the low resolution image sensor is then applied to the zoom interpolator, which processes the output signal so that the size of a display image obtained from the low resolution signal corresponds to the zoom setting of the zoom lens.

Abstract: Modification of process control signals so as to enable electrostatographic reproduction apparatus, including a dielectric support member transported about a path into operative association with electrographic process elements to form an information reproduction on a receiver member and a process controller for receiving and sending appropriate timing control signals in an expected value range for controlling the electrographic process, to operate over an alternate process range. For the desired signal modification, an input signal in a particular value range is received. A predetermined gain is applied to the received signal, and thereafter a predetermined offset is applied to the signal as modified by the gain application. The signal derived by gain application and offset is then emitted at an alternate value range to effect process control.

Abstract: Printer defining a reduced exterior envelope and method of providing same. The printer comprises a housing having a top wall. The printer also has a front side wall with an aperture for receiving a dye-carrying cartridge therethrough. A printhead is disposed in the housing. A movable platen is disposed in the housing in a first position spaced-apart from the printhead and a movable arm attached to the platen and engageable with the cartridge as the cartridge is received through the aperture. The arm moves from a first location to a second location thereof as the arm engages the cartridge and the platen moves from the first position to a second position thereof adjacent the printhead as the arm moves from the first location to the second location. In this manner, the printer defines a reduced exterior envelope because the cartridge is loaded through the aperture in the front sidewall rather through the top wall of the printer.
