Abstract: A bond coating material providing unexpectedly high thermal cyclic fatigue resistance and sulfidation resistance, and unexpectedly prolonged thermal cycle life in high temperature environments of gas turbine engine components with and without the presence of sulfur contains: a) 10% to 30% by weight chromium, b) at least one of tantalum and molybdenum in a total amount of 3% to 15% by weight, c) 5% to 13% by weight aluminum, d) 0.1% to 1.4% by weight silicon, e) 0.1% to 0.8% by weight yttrium, f) 0% to 1.2% by weight carbon, g) 0% to 1% by weight dysprosium, h) 0% to 1% by weight cerium, i) the balance being nickel, and the percentages of a) to i) adding up to 100% by weight. The total amount of tantalum and molybdenum, and the amounts of aluminum and silicon are each critical for avoiding delamination of a top coat from a bond coat.

Abstract: A swing set designed to have improved structural integrity wherein the swing set includes components manufactured from either 3500 psi concrete or 5000 psi concrete. The swing set includes a first vertical column and a second vertical column that are in axial alignment and further include a portion thereof inserted into the ground. The first vertical column and second vertical column are superposed concrete mounting pads. A horizontal crossbeam is coupled to the upper ends of the first vertical column and second vertical column and functions to have a plurality of swings suspendedly mounted thereto. The first vertical column and second vertical column further include a mounting structure operable to mateably couple with a portion of the horizontal crossbeam. The aforementioned swing set elements additionally include metal support bars of varying sizes and additionally have stirrups coupled thereto wherein the stirrups vary in distance between centers.

Abstract: A structural capacitor includes a first carbon fiber material layer, a second carbon fiber material layer, and an interlayer dielectric including a diamond-like-carbon material layer.

Abstract: In an oxidation process in a shell and tube reactor (10), an improvement is disposing a short bed of packing material (30) about the tube (50) inlets. The short bed operates to direct contaminants derived from heat exchange media away from the headspace (20) and thus prevents formation of combustible gas mixtures.
