Abstract: A focal plane assembly facilitates a molybdenum base plate being mounted to another plate made from aluminum. The molybdenum pin is an interference fit (press fit) in the aluminum base plate. An annular cut out area in the base plate forms two annular flexures.

Abstract: Methods are disclosed for producing multi-layer peelable sheaths having formed tips, for use as medical introducer devices, e.g., sheaths for inserting a catheter or the like into a patient. The methods include the steps of preparing a first composition blend for forming an inner layer of the multi-layer sheath, preparing a second composition blend for forming an outermost layer of the multi-layer sheath, combining the first and the second composition blends into a multi-layer pre-form, processing the multi-layer pre-form for producing tubing, and forming a tip at one end of the tubing using a thermal process, thereby producing the multi-layer sheath having the inner layer, the outermost layer, and the formed tip. The methods of the present invention include adding a detectable material to the blend used for making the inner layer for facilitating external visualization of the multi-layer sheath, thereby achieving a sheath with a formed tip having no visible discoloration.

Abstract: A raster image processor for an all points addressable marking engine includes a page memory having a data input and a write enable input. Halftone tints are applied to bit maps of objects stored in the page memory by applying a tint bit pattern to the data input of the page memory while a bit pattern representing the object is being applied to the write enable input of the page memory. Prior to applying the object bit maps to the write enable input of the page memory, the object bit maps may be combined with a texture bit pattern or clipped by a window bit pattern.

Abstract: Electrophotographic copying apparatus is disclosed having an elongated electrosensitive web defining a plurality of selectable image areas and having a plurality of perforations formed along an edge therein and movable along an endless path relative to a plurality of actuable work stations disposed along the path. The work stations are operative when actuated to perform a work operation on a selected image area of the web, respectively. The apparatus includes means disposed at a fixed location along the path for sensing the perforations to produce signals, a logic and control unit having a programmable computer with a stored program and responsive to such perforation signals for actuating the work stations in accordance with the program to cause the work stations to perform work operations on the web in timed relation to movement of selected image areas along the path respectively.
