摘要： A radiographic silver halide film has improved processability because it includes a silver halide emulsion composed of cubic grains having a critical molar ratio of chloride, iodide, and bromide. In particular, the cubic grains comprise from about 1 to about 20 mol % of chloride and from about 0.25 to about 1.5 mol % of iodide, with the remainder being bromide. The cubic grains also have an ECD of from about 0.65 to about 0.8 &mgr;m. This film is particularly useful in mammography for imaging dense soft tissue.

摘要： A radiation-sensitive emulsion is disclosed comprised of cubic silver iodochlorobromide grains comprising 0.25 to about 1.5 mol % iodide, 1 to about 25 mol % chloride, and from about 73.5 to 98.75 mol % bromide, each based on total silver in the emulsion, wherein the grains have an average equivalent circular diameter of greater than 0.6 micrometers and contain from 10−7 to 10−3 mole per silver mole of a metal ion coordination complex dopant of Formula (I) in an internal region of the grains formed after 10 percent and before 95 percent of the total grain silver has been precipitated: [ML6]n (I) wherein n is zero, −1, −2, −3 or −4, M is a filled frontier orbital polyvalent metal ion, other than iridium, and L6 represents bridging ligands which can be independently selected, provided that at least four of the ligands are anionic ligands, and at least one of the ligands is a cyano ligand or a ligand more electronegative than a cyano ligand. Doping of relatively large grain silver iodochlorobromide cubic grain emulsions in accordance with the invention provides optimized speed, contrast and low intensity efficiency.

摘要： A high quality direct radiographic film is useful for dental care. The film contains relatively high silver coverage preferably coated on both sides of the support. It also contains sufficient silver halide desensitizer to reduce silver halide sensitivity to X-radiation by at least 0.02 log E. The combination of silver and desensitizer coverages provides sufficiently high photographic speed, excellent image quality and increased stability to background radiation sources.

摘要： An optical cable comprises a longitudinally extending flexible central reinforcing member, e.g. a steel wire or wires; a layer of compressible material, such as cellular rubber or cellular plastics material, surrounding the reinforcing member; a plurality of separate optical fibres stranded side by side about the central reinforcing member in such a way that each optical fibre is in contact with the layer of compressible material; and, surrounding the optical fibres, an outer protective sheath. When the separate optical fibres are subjected to a tensile force, at least some of them can move transversely inwardly of the cable to compress the compressible material and thereby reduce the strain that would otherwise be imparted to the fibres.
