Show moreA process and apparatus for pulverization of natural and synthetic polymeric material by heating to a pre-melt or softening temperature below its melting point, cooling and applying normal and shear stresses sufficient to form fine powder, and fluidizing the powder in a gas stream preventing its agglomeration. The same process and apparatus is suitable for enhancement of reactivity of polymeric and solid monomeric material to form homopolymers, copolymers, and new polymeric materials.

Show moreA method and apparatus for producing ultrafine metal powders in which a laser beam is focused on the surface of a workpiece or feedstock and moved thereacross so as to create a cavity within the workpiece through melting and vaporization that contains the metal melted to form the cavity. A subsonic pulsating blast of inert gas is directed at the cavity to atomize the molten metal, rapidly cool the resulting droplets, and transport the droplets to a collection area. The cavity formed by the laser beam is a "keyhole" of deep cavity having a depth approximately three to four times greater than its width. The focal point of the laser beam is moved across the workpiece at a rate from approximately 50 to 80 inches per minute to ensure that the molten metal remains in the cavity prior to the gas atomization. Alloy metal powders can be produced by this method of laser blast atomization providing an alloying metal at the base metal where the cavity is formed so that, upon melting of the base metal, the alloy metal will melt into solution with the molten base metal in the cavity prior to gas atomization. Additionally, nonmetallic impurities may be removed from the molten metal contained within the cavity formed by the laser beam by vaporization.

Show moreA coiled metal sheet is placed in a container, which may be thereafter evacuated slowly with the strip outgassing, and then the highly evacuated container is sealed with the coiled strip therein. The evacuated container may be stored until ready to be mated with a high vacuum process chamber. The container is brought to the vacuum processing chamber and is connected thereto; and the coiled strip is unwound from the container and passed through the vacuum chamber, where it is treated while under a high vacuum. The treated strip is then preferably wound in a highly evacuated take-up container.

Show moreA method of providing acceleration support to a combustion engine using an integrated starter/alternator. The integrated starter/alternator is in rotational combination with the crankshaft and connected to a battery system. The integrated starter/alternator is adapted to function at times as a power source adding torque to rotate the crankshaft to overcome friction and non-linear hydrodynamic forces within the engine. At other times the integrated starter/alternator functions as a power generator for subtracting torque from the crankshaft to provide electrical current to the battery system.

Show moreA method for the construction and utilization of a medical records system capable of providing a continuous data stream of epidemiological data to the records system via kits provided to the symptomatic population to obtain and record an epidemiological profile in a searchable database by applying data mining or automated intelligence techniques whereby, when a valid epidemiological profile is established in the database, automated diagnosis and prescription of treatment may be had for patients presenting similar symptoms. Knowledge discovery techniques may further operate on the database to provide suggested courses of treatment for a virtual class of patients, epidemic threat awareness, and knowledge of drug resistance mutations by a pathogen without direct query of the database.

Show moreA digital controller for controlling variable speed and dynamic torque applications of an electric motor. The controller includes a state observer monitoring a torque load requirement and sending a signal based on the torque load requirement, and a digital control unit for receiving the signal from the state observer and sending an output to the electric motor. The output is a value that corresponds to a first motor operating state or a second motor operating state.

Show moreA process and apparatus for pulverization of thermosetting, crosslinked thermoplastic and natural polymeric materials by applying normal and shear stresses by oppositely rotating meshing conical screws sufficient to form fine powder. The process may be conducted at relatively low temperatures, and in the case of many materials, at ambient or near ambient temperature and pressure conditions. The fine powder may be fluidized to aid in its discharge.

Show moreA method of making a magnetic transducer head or element thereof from a binary alloy of silicon and iron, preferably containing from about 3 percent to 7 percent of silicon by weight, including provision of a grain-oriented silicon-iron core, annealing the core at a temperature above the Curie point in a dry hydrogen atmosphere and during cooling from that temperature subjecting the core piece to a magnetic field applied in the direction of the working flux at the core. The annealed core piece is formed so as to provide a gap-defining face for coupling to a magnetic record medium, the gap being of the order of about 1 micron.

Show moreA portable video recording system, particularly for amateur video reporting operations and the like, employing a camera station and a recording station which are physically separated from one another and connected over wireless links, the camera station being of a size to be readily manually carried on the person and designed merely to produce video and associated signals and transmit the same by radiation of a high frequency carrier, light or other signal to the recording station, and processed by receiving means thereat to derive the signals to be recorded, the recorder being operatively controlled from the camera station, whereby both the camera and the recorder of the remote recording station are under the control of the camera operator. Signals are also transmitted from the recording station to the camera station for indicating to the camera operator the operation of the recorder. Such indicating means may be a video monitor, an audio signal such as a tone signal, a visual signal such as an indicator light, or a combination thereof. Means also may be provided for effecting a selective switching, whereby a video signal may be returned to the camera either from the play-back head during recording operations, or from the recording head when the recording mechanism is not in operation.

Show moreIon exchange resins contaminated with a radioactive component are treated by exposing the contaminated ion exchange resins to a bound radio frequency electric field for uniformly heating them to drive off water. The dried ion exchange resins are then uniformly heated by a transversely uniform bound radio frequency electric field to a second higher temperature which chemically inactivates the functional groups of the ion exchange resins to destroy their hydrophilic property and convert them to a stabilized product for long-term safe storage.
