摘要： A unitary intensifying screen and radiographic element are disclosed comprised of adjacently coated silver halide emulsion and X radiation absorbing fluorescent layers. The fluorescent layer (a) is capable of attenuating at least 5 percent of a reference X radiation exposure produced by a Mo target tube operated at 28 kVp with a three phase power supply, wherein the reference X radiation exposure passes through 0.03 mm of Mo and 4.5 cm of poly(methyl methacrylate) to reach the fluorescent layer mounted 25 cm from a Mo anode of the target tube and attenuation is measured 50 cm beyond the fluorescent layer, (b) contains a phosphor which exhibits a conversion efficiency at least equal to that of calcium tungstate, (c) exhibits modulation transfer factors greater than those of reference curve A in FIG. 3, and (d) exhibits an optical density of less than 1.0. The emulsion and fluorescent layers are contiguously coated or optically coupled through a transmission medium transparent to latent image forming radiation and having a refractive index of at least 1.33, and the silver halide emulsion layer contains an agent for promoting the oxidation of silver atoms to silver ions to offset the effects of background radiation.

摘要： A method of mammography imaging includes exposing a patient to a peak voltage greater than 29 kVp using X-radiation generating equipment comprising rhodium or tungsten anodes. The film used in this method comprises a cubic grain silver halide emulsion layer on one side of the support and a tabular grain silver halide emulsion layer on the other side. The cubic grain silver halide emulsion layer comprises a combination of first and second spectral sensitizing dyes that provides a combined maximum J-aggregate absorption on the cubic silver halide grains of from about 540 to about 560 nm. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine, the second spectral sensitizing dye is an anionic oxycarbocyanine. The cubic grain silver halide emulsion layer also includes a mixture of gelatin or a gelatin derivative and a second hydrophilic binder other than gelatin or a gelatin derivative. The cubic silver halide grains comprise from about 1 to about 20 mol % chloride and from about 0.25 to about 1.5 mol % iodide, both based on total silver in the cubic grain emulsion layer, which cubic silver halide grains have an average ECD of from about 0.65 to about 0.8 μm. Moreover, the cubic silver halide grains are doped with a hexacoordination complex compound within part or all of the innermost 95% of the grains. The film can be exposed to provide a black-and-white image having a d(γ)/d(log E) value greater than 5.

摘要： A process and system for vacuum impregnation of a fiber reinforcement, such as carbon cloth, with a resin to produce a resin-fiber composite. Liquid resin enters in arrangement or system comprising a fiber reinforcement layer on a tool or mold and is directed via a system of flow paths to impregnate the fiber reinforcement layer uniformly across the width thereof and along the length of the fiber reinforcement layer. According to one embodiment, a fiber reinforcement layer, e.g., carbon cloth, is placed on a tool. A porous paring film is applied over the fiber reinforcement layer and a bleeder layer, e.g., fiberglass, is applied over the parting film. A non-pourous film is placed over the bleeder layer, a breather cloth, e.g., fiberglass, is then applied over the non-porous film, and a vacuum bag is placed over the entire assembly and sealed to the mold surface. Liquid resin is fed to the assembly within the vacuum bag. Resin spreader means, e.g., a transverse strip of fiberglass cloth, or mechanical means, such as a slotted tube, receives the liquid resin and distributes it initially across the panel adjacent one end of the reinforcement layer after the vacuum has been applied to the assembly. The liquid resin is drawn through the bleeder cloth and through the fiber reinforcement layer from one end to the opposite thereof to completely impregnate same. The resin system is designed so that it will commence to gel when the liquid resin has completely impregnated the fiber reinforcement layer.

摘要： A method for processing a life insurance facultative case summary submission over a network between a ceding company and a reinsurer. Initially, a facultative case summary submission is received by the reinsurer from the ceding company via the network. Thereafter, a facultative decision is rendered by the reinsurer based on the received facultative case summary submission. Because the information is summarized and sent electronically or via voice message, less information is processed in a faster period of time thereby rendering quicker decisions than when the complete case history is submitted to the reinsurer for review.
