Abstract: An ion-beam based system enables quantitative analysis and visualization of a sample with atomic and molecular specificity. The system comprises a liquid metal ion source that directs a tightly focused beam of ions at the sample, the beam having an ion density that is insufficient to materially change the surface properties of the sample. A controller connected to the liquid metal ion source gates on the ion beam for a period of time that is sufficient to enable the ion source to achieve a tight focus of the beam at the sample and for further scanning the ion beam across the sample. A laser beam is positioned over the sample and has a wavelength that resonantly ionizes components of the sample that are liberated by action of the scanned ion beam. A detector measures the liberated ionized components and is connected to a display system that provides an image of the distribution of the species on surface of the sample.

Abstract: An improved method for detecting an incipient failure in a multiphase electric motor includes the following steps: periodically measuring or continuously monitoring voltage and current values at each input to the motor; determining negative sequence voltage and current values for each periodic measured input voltage and current value; calculating an effective negative sequence impedance phasor value angle from each of the determined negative sequence voltages and current values; and comparing the calculated negative sequence impedance phasor angles and/or real and imaginary components over a plurality of periodic measurements to detect a change therein, which change is indicative of an incipient failure mode.

Abstract: Polymeric hydrocarbons having reactive borane groups at chain ends or in the polymer chain are described. These types of polymers can be used as intermediate materials for preparing a broad range of polymers which have functional groups located at both ends of the polymer chain (telechelic polymers). The process of preparing the borane-containing polymers involves metathesis degradation of the polymer at the double bond locations in the backbone and simultaneous functionalization of the broken chain ends by borane monomers. Depending on the nature of the borane monomer, the location of boron atoms can be controlled to be at either the chain ends (telechelic) or in the polymer backbone. The concentration of boron in the resulting polymer is related to the reaction time and the mole ratio between borane monomer and the double bonds in the starting hydrocarbon polymer. In turn, the borane groups are interconvertible to various functional groups, such as OH, NH.sub.2, and halides, under mild reaction conditions.

Abstract: An apparatus is disclosed for performing thermomechanical processing of gears in which precise control of the thermal, metallurgical and mechanical action during the forming process is maintained. The apparatus comprises an induction heating system which reaustenitizes the surface of the gear with minimum decarburization, a material transfer system which provides timely operations on the work piece, tooling and fixture adjustments which provide accurate initial conditions for forming, and a process control architecture that provides the precise sequence and timing necessary to achieve metallurgically sound and dimensionally accurate gears. Using this invention the induction heating cycle can be controlled from the peak, average or minimum gear surface temperature detected with a high response optical pyrometer. An inert environment is maintained around the workpiece during the induction heating and transfer to quenching above the M.sub.s temperature.

Abstract: An apparatus for mixing fluids is described which includes a flexible tubular member disposed between opposed ends. Filling and clamp systems are placed adjacent each of the opposed ends, creating sealed chambers in the tubular member, each chamber including a reagent fluid. The sealed reagent chambers are separated by a mixing chamber, and all of the chambers are disposed within the tubular member. A spring driven plate pressurizes each of the reagent chambers. A control system is coupled to each of the clamp systems for selectively opening a channel between at least one reagent chamber and the mixing chamber, with reagent in a reagent chamber being forced, via the open channel, into the mixing chamber by the spring biased pressurizing plate.

Abstract: Apparatus is disclosed for measuring creep stiffness of a specimen, for example, asphalt cement, or other viscoelastic material, having a flexural modulus greater than approximately 1,000 psi. The specimen and the lower part of a loading mechanism are submerged in a constant temperature coolant thereby providing buoyant support to the specimen, preventing it from deflecting under its own weight, as well as providing means for controlling the test temperature. The coolant temperature is maintained to within approximately +/-0.1.degree. C. of a desired temperature. The specimen, having known dimensions, is supported within the coolant on two spaced apart support members. A loading head actuated by an air bearing/pneumatic piston mechanism engages the specimen midway between the two support members. The deflection of the specimen is measured with an LVDT and the load imparted to the specimen by a load cell provided under at least one of the specimen support members.

Abstract: A solid-state tunable transducer has been developed by incorporating an elastically nonlinear material, silicone rubber, into an electroacoustic transducer made from piezoelectric ceramics. The resonant frequency and mechanical Q of the transducer are tuned mechanically by applying a uniaxial compressive stress to the composite. The resonant frequency is tuned electrically by placing a piezoelectric actuator into the composite and varying the magnitude of the d.c. bias.

Abstract: The 700.degree. C./4 min. rapid thermal anneal described in the prior art for converting amorphous Si to polycrystalline Si can be reduced to a temperature range of from 550.degree. C. to 650.degree. C. This is accomplished by depositing a very thin discontinuous film of a nucleating site forming material over the amorphous Si prior to rapid thermal anneal. Furthermore, by selectively depositing the material in a pattern, only that amorphous Si beneath the deposited pattern is caused to crystallize during annealing, while the remaining areas of amorphous Si remain in the amorphous state.

Abstract: A method for lowering the oxygen potential of an inert processing atmosphere containing a reducing gas such as hydrogen, by introducing a metal catalyst to induce reaction between the reducing gas and oxygen, which may originate from leaks into the system or from other sources. The catalyst, such as a precious metal, increases the rate of reaction between gaseous hydrogen and gaseous oxygen to form water vapor, thereby decreasing the amount of molecular oxygen available to react with oxidizable materials exposed to the inert processing atmosphere.

Abstract: Hexachlorocyclotriphosphazene and poly(dichlorophosphazene) react with the sodium salt of ethyl p-hydroxybenzoate to give small molecule cyclic and high polymeric phosphazenes with aryloxy ester side groups; reaction of these compounds with potassium tert-butoxide brings about complete hydrolysis of the ester groups to yielding aqueous media-soluble, carboxylic acid bearing cyclic and high polymeric phosphazenes; the carboxylic acid bearing high polymer formed ionic cross-links when treated in aqueous media with salts of di- or trivalent cations yield hydrogels and membranes. The cross-linked gels were stable in neutral or strongly acidic aqueous media, but the cross-linking process was reversed in basic aqueous solutions of excess monovalent cations.

Abstract: This invention describes an acoustic transducer assembly wherein an extremely high figure of merit (d.sub.h g.sub.h) is obtained as a result of converting incoming acoustic axial stress into radial extensional stress thereby multiplying its effect. The piezoelectric active element is encased in a metal sandwich enclosing two semilunar air spaces which allow the device to withstand extremely high hydrostatic pressure yet still respond to low level sound waves when acting as a hydrophone. The mechanical prestress induced by the differential coefficients of expansion between the metal case and the piezoelectric ceramic element also serves to prevent depolarization aging.
