    Abstract: A magnetometer is integrated with a miniature vibrating beam accelerometer fabricated out of silicon on a common substrate. Dual pendulum-DETF force sensing accelerometers have integrated conductor coils on the pendulums that circulate alternating current to cause an additional pendulum motion also sensed by the DETF transducers for sensing local earth magnetic field. The integrated magnetic and acceleration sensing is used for each of three reference axes in a triaxial inclinometer magnetometer for borehole drill steering and surveying.

    Abstract: Coextruded films having a one inner core layer of polyamide homopolymer or copolymer, and an outer layer on each side of the polyamide core of a blend of a polyolefin homopolymer or copolymer and an adhesive composition which comprises a polyolefin having at least one functional moiety of an unsaturated carboxylic acid and/or anhydride thereof. The coextruded films are typically prepared by a blown film technique. Such structures are suitable for use as release and barrier films for sheet molding and other reinforced plastic applications.

    Abstract: A nickel-chromium-based brazing alloy has a composition consisting essentially of about 9.5 to about 16.5 atom percent chromium, 0 to about 5 atom percent iron, about 10 to about 15 atom percent silicon, about 6 to less than 7 atom percent boron, and 0 to about 5 atom percent molybdenum, the balance being essentially nickel and incidental impurities. The alloy is especially suited for use as a brazing filler metal for joining stainless steel and/or superalloy at temperatures above 1100 degree(s) C. Such a filler metal has a thickness ranging from about 65 to 100 micrometers and a width ranging from 100 to 250 millimeters and more. Honeycomb structures and thin corrugated fin/plate structures particularly suited for use in manufacture of plate-type heat exchangers formed at least in part from stainless steels and/or superalloys are brazed using a unique process. The process is characterized by a long holding time at brazing temperature, and combines brazing and diffusion annealing in one technological step. Brazements produced by the process exhibit complete disappearance of central eutectic line and britlle intermetallic compounds from the joint microstructure. The brazements further exhibit joint ductility, as well as high strength and fatigue and corrosion resistance.
