摘要： A multi-ply radiation dosage indicator, and method of manufacture, is disclosed including a first ply having visible indicia thereon and a second ply having a radiation sensitive zone overlying the indicia of the first ply. The radiation sensitive zone is capable of changing opacity in response to exposure to a radiation dosage exceeding a predetermined threshold so as to change the visibility of the indicia thereby providing an indication as to whether the indicator has become irradiated. An optical filter ply may be provided overlying the indicia, and the indicator also may be provided with a transparent protective outer ply. A pressure sensitive adhesive ply having a removable release sheet is employed for attaching the indicator to a substrate.

摘要： A memory element for an electron beam target comprising an electrically insulating support laminated to a conductive layer which, in turn, is laminated to a dielectric surface layer having a thickness less than 1 micrometer, e.g. 0.04-0.8 micrometer, a resistivity of at least 10.sup.16 ohm-cm and a dielectric strength of at least 10.sup.5 volts/cm; said dielectric surface layer comprising a material sensitive to electron beam irradiation and provided, essentially coplanar with its exposed surface, with focusing means or indicia in the form of shaped patterns that provide reference points for locating recording or retrieval points during electron beam exposure and scanning of the target surface.Writing is accomplished by irradiating with an electron beam either to develop a charge pattern or to alter the state of polymerization of cross-linking or both in a prescribed pattern for transmitting data. Where polymerization or cross-linking is involved, the material is altered such that subsequent contact with a solvent selectively removes the material in the state of lesser polymerization, leaving behind permanent islands of the unremoved material. By assigning a given logical meaning to the permanent islands or to the charge stored in the dielectric layer, for example, a dual character code is provided such that digital data can be stored. The focusing means or indicia allow addresses to be located in the memory element with sufficient precision that in excess of 10.sup.8 bits/cm.sup.2 can be recorded and retrieved.

摘要： A window processing system is disclosed for fabricating window frames. A welding station has welding heads to weld or fuse vinyl frame parts together. The frames are taken to a cleaning station having a number of cleaning heads that are independently actuated to move into a position relative selected portions of the window frame to clean off burrs, weld beads etc from the welded window frame. The cleaning process involves both training of a controller to recognize certain frame profiles and a compensation process for adjusting the cleaning process for individual variations in the frame that occur during fabrication. Real-time cleaning involves coupling a visual sensor to a moving support that also supports a cleaning tool.
