20110107775 | Parallel Condensing Unit Control System And Method - A system comprises a condenser for a refrigeration system and a control module. The condenser has a plurality of variable speed condenser fans. The control module controls the plurality of variable speed condenser fans. The control module increases condenser fan operation by activating a deactivated variable speed condenser fan at a first fan speed when at least one variable speed condenser fan of the plurality is deactivated and by increasing a fan speed of an activated variable speed condenser fan to a second fan speed when each variable speed condenser fan of the plurality is activated and operating at the first fan speed. The second fan speed is faster than the first fan speed. | 05-12-2011 |

20100324852 | DETERMINING THE RESONANCE PARAMETERS FOR MECHANICAL OSCILLATORS - The prior art describes the application of mechanical oscillators for the measurement of corrosion and/or deposition. Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. However, the prior art does not consider the required precision for measuring frequency or Q in the presence of noise to make these measurements. In particular, the ability of the mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. The present invention discloses methods for measuring these resonance parameters with a high precision in the presence of noise. This degree of precision is required to maximize the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. All of the embodiments described herein employ curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds considerable precision in measuring resonance parameters. | 12-23-2010 |

20080314150 | Mechanical oscillator activated or deactivated by a predetermined condition - The present invention is a mechanical oscillator for detection and measurement of corrosive or foreign materials. The elements include a means for mechanical excitation, and a mechanical oscillator, wherein said mechanical oscillator has a resonant frequency, f, and a quality factor, Q. A fuse fixed to the oscillator to change oscillator amplitude to or from essentially zero to resonance amplitude. In a preferred embodiment, the mechanical oscillator has the shape of a tuning fork where one region is compatible with the service fluid and the other region is incompatible with the service fluid or other contaminant. The sensor alarms when a measured amount of the incompatible material has been removed or the physical strength of the material has been compromised. | 12-25-2008 |
20120130026 | MITIGATION OF ELASTOMER REACTOR FOULING USING MECHANICAL VIBRATION - Method of reducing fouling in an elastomer polymerization process that includes providing a reactor capable of housing an industrial-scale elastomer polymerization reaction, and applying a mechanical force to the reactor so as to create a vibration in at least one wall of the reactor, in which fouling is reduced in the reactor. In one embodiment the reaction is an industrial scale butyl polymerization reaction and the reactor is a butyl polymerization reactor. | 05-24-2012 |

20100286876 | POWER SPLIT DEVICE AND METHOD - A variable power split device having radially inner and outer races, each comprising at least two axially spaced parts. A plurality of planetary members are arranged for rolling contact between the races and a planet follower carrier engages the planetary members. A first rotatable power element spindle connects with the planet follower to couple power between the planet follower carrier and a first power element. A second rotatable power element spindle connects with the inner race to couple power between the inner race and a second power element. A third rotatable power element spindle connects with the outer race to couple power between the outer race and a third power element. Means for adjusting axial separation adjust separation of the axially spaced parts of at least one of the races to vary a power split ratio between the first, second and third rotatable power element spindles. | 11-11-2010 |
