Abstract: A low temperature method for reducing and purifying refractory metals, metal compounds, and semi-metals using a catalyst. Using this invention, TiO2 can be reduced directly to Ti metal at room temperature. The catalyst is an ion in an electrolyte that catalyzes the rate of the reduction of a compound MX to M, wherein M is a metal or a semi-metal; MX is a metal compound, a semi-metal compound, or a metal or semi-metal dissolved as an impurity in M; and X is an element chemically combined with or dissolved in M.

The second end is attached to the device portion. There is at least one pair of parallel insertion guides extending from the first end of the attachment portion to substantially the second end along the inner surface. The insertion guides are separated by an insertion slot created by an insertion slot base disposed between the insertion guides and adjacent to the inner surface. The insertion base has a first thickness at the first guide end and a second thickness greater than the first thickness at the second guide end.

Abstract: Disclosed is a portable air filtration system for removing contaminants from room air. In one embodiment, the air filtration system includes a power supply and an air blower module electrically connected to the power supply. The air filtration system further includes an ionization module engaged with the air blower module and including a first control grid and a high voltage grid electrically connected to the power supply.

Abstract: A system for first setting a blind rivet and then verifying the correctness of the set comprising a rivet setting tool to set the rivet and computer logic to verify the correctness of the set. The setting tool includes a jaw assembly for holding the stem of the rivet's mandrel fitted to an axially movable pulling shaft. Both the pulling force of the setting tool and the displacement of the pulling shaft are measured and the measurements are interpreted by an integrator to determine the total energy of the setting process. The determined total energy is then compared with an ideal total energy to assess whether or not the set of the particular rivet is acceptable. Other quantitative comparisons may be made against other ideal values.

Abstract: A tool for setting blind rivets. The load of the motor which drives the pulling head between fully forward and retracted positions is monitored. When the pulling head is displaced to set a rivet motor direction will be changed if a moderate load is not sensed in a short period of time or if following such sensing of a moderate load the sensed low drops to a minimum value. When the pulling head is displaced in the opposite direction a stop will be engaged at the fully forward position and the sensing of a moderate load will stop the motor.

Abstract: A MESFET wherein a Schottky top gate which extends across the channel region between the source and drain regions and beyond sides of the dielectric isolation in which the device is built at two points. The bottom gate also extends beyond the dielectric isolation below the surface of the island and intersects the bottom of the source and drain regions. Where a bottom gate contact region forms an annulus encompassing the source and drain, the top gate extends across the channel and only onto sides of the bottom gate contact region at two points. The source and drain regions which are formed are sufficiently spaced from the dielectric isolation so as not to effect the I.sub.DSS resulting from variation in the island size.
