Abstract: A high-speed cold laminating system including a cartridge having two rolls of pressure-sensitive laminating film. The goes into a receptacle of the laminating system. A steering module is upstream of the pressure rollers and a cutter is downstream of the pressure rollers. The steering module orients and positions sheets with respect to a directional path. The cutter severs a length of the laminating film containing a sheet from the remaining laminating film. A controller controls the conveyance of sheets and is programmed for bi-directional communication with an EEPROM of the cartridge. The EEPROM provides information to the controller regarding the laminating film, and the controller tracks film consumption within the system. The controller is programmed to periodically update the EEPROM of the laminating film cartridge with a current remaining film length during use within the laminating system based on the laminating film consumption tracked by the controller.

Abstract: A high-speed, cold laminating system includes a lamination unit for inline use connected with a paper feeder supplying at least 30 ppm. The lamination unit further includes a set of unheated motor-driven laminating pressure rollers along a laminating path, and a cutter between the rollers and an exit. A diverter gate passes the paper sheets to the laminating path or to the exit without passing along the laminating path. The system includes a controller to control the motor, the diverter gate, and functions of the lamination unit. The controller is programmed to control the motor to pause the pressure rollers with a leading sheet therein while a subsequent sheet moves toward the pressure rollers so a laminated spacing distance between a trailing edge of the leading sheet and a leading edge of the subsequent sheet to equal a prescribed spacing distance.

Abstract: The present invention provides methods for enhancing chemical reactions of molecules, e.g., biomolecules, with destructible surfactants. The chemical reactions may involve and/or be associate with analysis, e.g., solubilizing, separating, purifying and/or characterizing the molecules. In one aspect, the anionic surfactants of the present invention may be selectively broken up at relatively low pH. The resulting breakdown products of the surfactants may be removed from the molecule/sample with relative ease. The invention has applicability in a variety of analytical techniques.

Abstract: A method is provided for microelectropolishing a transmission electron microscopy nonhomogeneous multi-element compound foil. The foil is electrolyzed at different polishing rates for different elements by rapidly cycling between different current densities. During a first portion of each cycle at a first voltage a first element electrolyzes at a higher current density than a second element such that the material of the first element leaves the anode foil at a faster rate than the second element and creates a solid surface film, and such that the solid surface film is removed at a faster rate than the first element leaves the anode foil. During a second portion of each cycle at a second voltage the second element electrolyzes at a higher current density than the first element, and the material of the second element leaves the anode foil at a faster rate than the first element and creates a solid surface film, and the solid surface film is removed at a slower rate than the second element leaves the foil.
