Abstract: Two Nb.sub.3 Sn superconducting tapes are overlapped by an amount equal to about two times the width of the superconducting tapes. A filler material of material substantially similar to the tapes is placed between the two tapes in the overlapped region. A NdYAG laser (4) sends a 20-40 watt beam focused by a lens that heats the tapes to create a bridge of superconductivity material formed over the region where the tapes are joined.

Abstract: A method for forming a porous carbonaceous preform includes forming a mixture comprised of up to about 50 volume percent of furfuryl alcohol or tetrahydrofurfuryl alcohol, about 1 to 10 volume percent of a nonionic polyethylene oxide polymer ranging in molecular weight from about 100,000 to 5,000,000, about 30 to 80 volume percent of a carbonaceous material, and the balance water. The mixture is cast to form a body, and heated to decompose the polymer and form the porous preform. A molding composition for carbonaceous material includes, up to about 50 volume percent of furfuryl alcohol or tetrahydrofurfuryl alcohol, about 1 to 10 volume percent of a nonionic polyethylene oxide polymer ranging in molecular weight from about 100,000 to 5,000,000, about 30 to 80 volume percent of the carbonaceous material, and the balance water.

Abstract: A method for improving eddy current flaw detection by simultaneously exciting a select plurality of eddy current probe elements with a multiplicity of select frequencies in a simultaneous parallel or serial manner to form a corresponding multiplicity of direct and/or differential images which can be processed together for improved eddy current image resolution. Select eddy current probe elements when driven at select multiple frequencies further provide a capability for simultaneous flaw detection and characterization by dual resolution scanning. Dual flaw resolution is accomplished by first locating a flaw using low resolution frequencies; and thereupon, switching to higher resolution frequencies to characterize the flaw.

Abstract: In order to reduce emissions of NO.sub.x, CO and unburned hydrocarbons, the flame temperature must be kept between 2500.degree.-2800.degree. F. Premixing combustor tubes are used to premix the fuel and air before the mixture is burned in the combustion chamber. The tubes are flashback resistant due to the flow of the fuel and air mixture through them. If it is desired to reduce the load operation of the combustor to substantially below 100% of its maximum load operation, as is the case during off-peak hours, the fuel and air flow rate can be regulated to reduce the load operation while still keeping the low emissions and the low flame temperature.

Abstract: This invention relates to methods for measuring surface treatment coverage, and more particularly, to such methods for measuring shot peening coverage. Such methods generally employ an automated computer analysis of the peened surface coverage by analyzing surface line traces to determine when a particular surface has been surface hardened enough.

Abstract: A method of imaging and quantitatively measuring blood velocity distribution within a selected vessel employs Nuclear Magnetic Resonance excitation of a number of regions of a subject to be imaged by an rf excitation pulse applied in a magnetic field gradient. The rf excitation pulse has several frequency bands with the frequencies between the bands having essentially no amplitude. A frequency band causes excitation of a region of the subject. Each frequency band is encoded with a unique phase angle offset so that the signals from each region may be separated. The excited regions are Fourier velocity encoded along a second axis based upon their flow velocities. A re-radiated signal is acquired in the presence of a readout gradient to provide resolution along a selected axis and reconstruct a velocity profile. This method can be combined with cardiac synchronization to measure flow dynamics or it can be applied without synchronization to measure steady flow.

Abstract: A method for estimation and display of current source distribution within a living creature utilizes magnetic measurements taken outside of the living creature combined with 3D anatomical data generated from any procedure, such as MRI or CT scanning, which generates this type of anatomical data. The method is a modified minimum norm technique whereby the solution is limited to areas of the living creature where the electric source is expected.

Abstract: Apparatus for selectively regenerating at least one portion of an adsorbent bed in an adsorption system with a movable microwave device while the remainder of the bed is still being used. The adsorbent bed is held by a frame which divides the bed into a plurality of sections, each section holding a portion of the adsorbent. At least one movable regeneration carriage assembly which moves from section to section is provided. The carriage assembly supports a microwave heating device which heats the adsorbent in the section adjacent to the carriage assembly. Each section can be isolated from the others in turn and be regenerated while the remaining sections continue the adsorption function. The isolated section is swept by a purge gas which is conveyed to and from the section by flexible cords connected to the carriage assembly.

Abstract: An dynamoelectric machine is provided having a hollow shaft adapted to receive fluid at one end and to discharge it at the other. The hollow shaft has a stack of laminations mounted thereon. A hollow disk is situated adjacent to and in contact with an axial end of the stack of laminations. The hollow disk includes a generally circular baffle for dividing the hollow disk into two interior sections and to cause the fluid to rotate at the same angular velocity as the hollow disk. The two interior sections are in flow communication with one another of the periphery at the generally circular baffle. The hollow shaft is in flow communication with one of the sections for providing fluid and in flow communication with the other section for removing fluid. A stator surrounds the laminations and is spaced away therefrom.

Abstract: A system for reducing noise created by multiple rotating machines by synchronizing the machines so as to establish a phase relationship between the machines which minimizes the noise. One or more feedback sensors, such as microphones, are placed so as to sense the noise to be reduced. The noise signals from the microphones are sent to a controller. Tachometer signals of the rotational speed of each machine are also sent to the controller. The controller generates an output signal in response to the inputs from the microphones and the tachometers that is fed to one or more of the rotating machines in order to establish the desired phase relationships.

Abstract: The trajectory of a surgical instrument or tool used for a stereotactic medical procedure is controlled by a passive apparatus having two pivots into which the tool may be inserted. The pivots, which serve as end effectors, are placed at points along a selected trajectory. The pivots are mounted to members attached to carriages. The carriages allow movement in a plane, whereas the members may move perpendicular to the plane. Indicia allow the pivots to be moved to a desired point and fasteners then secure the pivots in place, while allowing the pivots free rotation relative to two perpendicular axes.
