Publication number: 20080136275Abstract: A plurality of fan blades are secured to a rotor assembly of a single directional motor. When the motor is powered on, a force generated by the fan blades pushes the rotor assembly in a direction of a low friction thrust interface. When the motor is backdriven in a direction opposite the powered direction, the force generated by the fan blades pushes the rotor assembly in a direction of a higher-friction thrust interface, causing a tapered surface of the pinion and a tapered surface of a bearing retainer to be pressed against each other to produce a frictional braking force. The backdriven speed of the motor and drive device is therefore reduced, improving the reliability of the motor assembly. The invention can be applied to motor actuators used to control air dampers and other valves in gas or fluid delivery systems. The invention can also be used to reduce water hammer in water delivery systems.Type: ApplicationFiled: December 11, 2006Publication date: June 12, 2008Applicant: Hansen CorporationInventor: Lincoln J.

Publication number: 20080136291Abstract: This invention relates to a system for exciting oscillations of micromechanical cantilever sensors and for measuring and evaluating the corresponding oscillations. Such sensors can e.g. be used to detect chemical substances, biomolecules, microorganisms or viruses, or to analyze surface-related phenomena and processes such as conformational changes or phase transitions in thin layers, or to measure physical properties of their surrounding, such as viscoelastic properties of liquids. In the so-called dynamic operation mode, cantilever oscillations are excited and the frequency shift of the ground frequency and/or of one or some higher harmonics, occurring because of a process taking place at the cantilever surface, are measured. In the so-called static mode, the deflection of the cantilever is determined. The setup described in this invention allows measurements in gases as well as liquids.Type: ApplicationFiled: December 11, 2007Publication date: June 12, 2008Applicant: CONCENTRIS GMBHInventor: Felice Mauro Battiston

Publication number: 20080136294Abstract: A self-regulating permanent magnet device has a first rotor segment and second rotor segment, each supporting a set of permanent magnets, wherein the position of the second rotor segment relative to the first rotor segment is modified based on the speed of the self-regulating permanent magnet device. By modifying the position of the second rotor segment relative to the first rotor segment, the alignment between their respective sets of permanent magnets, and therefore, the electromotive force (emf) generated in the stator coils is regulated. The position of the second rotor segment is defined by the connection of a torsion spring between the first rotor segment and second rotor segment and a reactionary torque device connected to the second rotor segment. The torsion spring creates a spring force that acts to maintain the alignment between the first rotor segment and the second rotor segment.Type: ApplicationFiled: December 6, 2006Publication date: June 12, 2008Applicant: Hamilton Sundstrand CorporationInventors: Theodore Clifton Powers, Michael Raymond Hernden, Mahesh J.

Publication number: 20080136296Abstract: The present invention is related to a desk structure. The desk structure comprises a writing surface, and a book box which is secured to the writing surface. A plurality of receiver sleeves are integrally molded with the book box. Each receiver sleeve has an outer wall and an inner wall. The inner wall of the receiver sleeve has a slot and a plurality of radially spaced ribs. The inner wall defines an opening. The desk structure further comprises a plurality of legs. Each leg has an upper leg portion. The upper leg portion of each leg is received by the inner wall opening of a corresponding receiver sleeve. Additionally, each upper leg portion includes a detent. The detent is adapted to engage a corresponding inner wall slot when the upper leg portion is received by the inner wall opening of the corresponding receiver sleeve. Thus, the detent both secures the leg to the book box and positions the upper leg portion within the opening.Type: ApplicationFiled: November 22, 2006Publication date: June 12, 2008Inventors: Mack Daniel Westbrook, Matthew Murphy Lafleur, Lewis Dorsey Cox, Jeffrey Stout
