Abstract: A permanent magnet brushless torque actuator is comprised of an electromagnetic core capable of generating an elongated toroidally shaped magnet flux field when energized.  Outside the generally cylindrical coil is an outer housing with upper and lower end plates at each end. Mounted to the end plates and extending towards each other are stator pole pieces separated from its opposing pole piece by an air gap.  A permanent magnet rotor is disposed in the air gap and mounted on a shaft which in turn is rotatably mounted in each of the end plates.  The permanent magnet rotor comprises at least two permanent magnets, each covering an arcuate portion of the rotor and having opposite polarities.  Energization of the coil with current in one direction magnetizes the pole pieces such that each of the two pole pieces attracts one of the magnets of the rotor and repels the other magnet of the rotor resulting in a torque generated by the output shaft.  Reversal of the current flow results in a reversal of the torque and rotation of the rotor in the opposite direction.  Preferred embodiments are disclosed having multiple cells, i.e. a plurality of stator rotor stator combinations and/or cells in which there are a plurality of pole pieces at each stator pole plane.

Abstract: A gas concentration and/or bulk flow rate sensor suitable for measuring the oxygen concentration and the bulk flow rate of gas delivered to a patient for medical purposes. Two piezoelectric transducers mounted on a printed circuit board are interconnected by an elongated coiled tube. The gas is flowed around one of the transducers, through the tube and around the other transducer. Periodically, one of the transducers is energized with a single short duration pulse to transmit a sonic wave through the gas to the other transducer. The travel time for the sonic wave is measured. The two transducers are alternately used as transmitters and receivers so that the wave travel time is measured both with and against the gas flow direction. A thermistor is located in the center of the coiled tube for measuring the temperature of the gas. From the measured times, the measured temperature and stored formulas, a microprocessor calculates the oxygen concentration and/or the bulk flow rate for the gas. The sensor also may be used to measure other components of a gas mixture.

Title: Method of forming structural panel assemblies
Inventor: MERSER N KEITH
IPC: B29C44/12
Filed: 1994-02-03
Granted: 1998-04-07
Abstract: The method of forming rigid panel assemblies of this invention eliminates the requirement for mechanical fasteners and may be used to bond wall boards to studs, floor joists to wood flooring such a plywood or OSB boards and trusses to ceiling panel. The method of this invention includes applying a thin bead of a thoroughly mixed two-component liquid polyurethane foamable resin adhesive on the surface where the components are to be joined. The foamable resin is formulated to provide a long tack time or delay curing until the assembly is complete. The foamable resin is then allowed to cream and rise before bonding. Where the bead is applied to the side faces of the support members, the support members are preferably turned to orient the foam beads over the fibrous panel, which is preferably supported on a flat horizontal support surface. Finally, the beads are compressed against the fibrous panel, wetting the panel with liquid foam resin before the foam has gelled, permanently bonding the support member to the panel and forming the structural panel assembly. Where an enclosed panel assembly, such as a closed wall is desired, the structural members are attached to a first panel, orienting the support members for application of the polyurethane foam bead, as described.
