Patent number: 5145743Abstract: An improved X-ray intensifying screen comprising phosphor crystals having an effective amount of a light scattering particulate material, e.g., barium sulfate, strontium sulfate, calcium sulfate, titanium dioxide or magnesium oxide, adhered thereto is described. This screen will give high speed and yield an image with increased sharpness when exposed with a single-side coated medical X-ray film element, compared to one made without the particulate material.Type: GrantFiled: October 25, 1990Date of Patent: September 8, 1992Assignee: E. I. Du Pont de Nemours and CompanyInventors: Jacob Beutel, Lothar H. Brixner

Patent number: 5011260Abstract: A buffered optical fiber (20) includes an optical fiber (21) comprising a core and a cladding. Typically, the optical fiber is enclosed by at least one layer (23) of coating material. The optical fiber is enclosed by a plastic buffer layer (30). Interposed between the optical fiber and the buffer layer is a decoupling material (40) which provides a controlled coupling of the buffer layer to the underlying coating material. As a result, there is sufficient adhesion between the buffer layer and the underlying coating material to maintain the buffer layer in place during normal use of the buffered optical fiber. On the other hand, the adhesion is low enough so that the buffer layer may be removed upon the application of resonably low stripping forces. Advantageously, the decoupling material also allows the selective removal of the optical fiber coating material as well as the plastic buffer layer.Type: GrantFiled: July 26, 1989Date of Patent: April 30, 1991Assignee: AT&T Bell LaboratoriesInventors: M. Fred Marx, Parry A. Moss, Mary J. Presnell, John W. Shea
