Abstract: This is a nickel-base superalloy with excellent weldability and high strength. Its composition consists essentially of, by weight percent, 10-20 iron, 57-63 nickel, 7-18 chromium, 4-6 molybdenum, 1-2 niobium, 0.2-0.8 silicon, 0.01-0.05 zirconium, 1.0-2.5 titanium, 1.0-2.5 aluminum, 0.02-0.06 carbon, and 0.002-0.015 boron. The weldability and strength of this alloy give it a variety of applications. The long-time structural stability of this alloy together with its low swelling under nuclear radiation conditions, make it especially suitable for use as a duct material and controlling element cladding for sodium-cooled nuclear reactors.

Abstract: A solid solution strengthened Ni-Cr-Fe alloy capable of retaining its strength at high temperatures and consisting essentially of 42 to 48% nickel, 11 to 13% chromium, 2.6 to 3.4% niobium, 0.2 to 1.2% silicon, 0.5 to 1.5% vanadium, 2.6 to 3.4% molybdenum, 0.1 to 0.3% aluminum, 0.1 to 0.3% titanium, 0.02 to 0.05% carbon, 0.002 to 0.015% boron, up to 0.06 zirconium, and the balance iron. After solution annealing at 1038.degree. C. for one hour, the alloy, when heated to a temperature of 650.degree. C., has a 2% yield strength of 307 MPa, an ultimate tensile strength of 513 MPa and a rupture strength of as high as 400 MPa after 100 hours.

Abstract: A vehicle for traveling alongside a burning airplane, on an airport runway, while pumping fire extinguishing fluid on the burning engines, wings or fuselage, is an elongated tank trailer with multiple rear wheel axles and a forward end supported on, and moved by a motorized tractor.The trailer includes a 5000 gallon water tank, foam tanks, a built-in motor and pump, foam spreader bars and an elevatable water tower.The trailer can pump from the nozzle of the elevated tower while advancing at the speed of the plane and includes mobile outrigger means to prevent overturning.

Abstract: A roller guide assembly for guiding a workpiece into the roll pass of a rolling mill has hydraulic or mechanical reaction means operable to apply a substantially constant load through the guide rollers to the workpiece irrespective of the lateral displacement of the rollers by the workpiece. The guide rollers are carried by pivotally mounted arms which extend lengthwise through the assembly housing and the reaction means bear against these arms.

Abstract: A modular fire-fighting unit can be used on the ground as an individual fire piece connected to a water source such as a hydrant, for producing foam or as a nurse unit to other fire apparatus, or it can be quickly mounted on, or demounted from, a portable source of water such as a 5,000 gallon tank truck, for producing foam to extinguish runway fires. The module includes a protein tank, an AFFF tank, an inflexible connection to a source of water, mixing valves and a motor driven pump so that foam may be dispersed from either a turret gun or an airport spreader bar.

Abstract: A work roll assembly for a cantilever-type rolling mill includes a work roll shaft which is drivable from one end and which has a locating spigot extending axially outward of the shaft at its other end. The annular work roll to be mounted to said shaft has an axial recess to receive the spigot. A hydraulic device is provided to urge the roll into engagement with the shaft so as to axially locate the work roll. The locating spigot is expandable in a radial direction to engage the cylindrical inner surface of the work roll recess so as to radially locate the roll to the shaft.

Abstract: A clamp-on valve structure for use in dispensing pressurized fluid from a can having an annular projecting lip. The valve structure includes mounting structure having a manipulatable portion which is effectively locked to prevent removal of the valve structure from the can with the valve installed on the mounting structure.
