20090193597 | APPARATUS FOR CLEANING A WOODWIND INSTRUMENT - The present invention provides an apparatus for cleaning a woodwind instrument including a housing and a motor mounted within the housing, the motor having a rotatable drive shaft extending outwardly from the housing. An elongated cleaning tool is coupled to the drive shaft and insertable into the tube portion of a woodwind instrument for cleaning the inner wall of the tube. The apparatus further includes an instrument support attached to the housing adjacent the cleaning tool. The instrument support defines a length aligned substantially parallel with the length of the cleaning tool for supporting the instrument during a cleaning process. The cleaning tool being rotatable via the drive shaft for cleaning the interior of an instrument positioned over the cleaning tool and supported by the instrument support. A strap is provided to secure the instrument to the instrument support. | 08-06-2009 |

20140360590 | High Reliability Pressure Relief Valve - A pressure relief valve is disclosed with a first stage valve that is in series with a second stage valve, with an enclosed cavity between the first stage valve and the second stage valve. The first stage valve relieves pressure from an enclosure into the enclosed cavity between the stages, when the pressure is above a cracking pressure of the first stage valve. The second stage relieves pressure from the enclosed cavity when the pressure is above the cracking pressure of the second stage valve. | 12-11-2014 |

20100009120 | PATTERN PRODUCTION AND RECOVERY BY TRANSFORMATION - A transformative periodic structure includes a plurality of elastomeric or elasto-plastic periodic solids that experiences a transformation in the structural configuration upon application of a critical macroscopic stress or strain. The transformation alters the geometric pattern changing the spacing and the shape of the features within the transformative periodic structure. For the case of elastomeric periodic structures upon removal of the critical macroscopic stress or strain, the transformative periodic solids are recovered to their original form. For the case of elasto-plastic periodic structures upon removal of the critical macroscopic stress or strain, the new pattern is retained. Polymeric periodic solids can be recovered to their original form by heating or plasticizing. | 01-14-2010 |

20140034614 | METHODS FOR CONTROLLING LASER CUTTING PROCESSES AND LASER CUTTING SYSTEMS IMPLEMENTING SAME - Laser cutting processes are provided which are controlled using as a reference signal one or more emission lines which are characteristic of the radiation emitted by a gas or, more generally, by an emitting element present in the volume irradiated by the laser beam focussed by a laser head and adjusting, on the basis of this reference signal, at least one of the following process control parameters: the power of the laser, the frequency and the duty cycle of the laser pulse, the pressure of an assisting gas emitted by a nozzle forming part of the laser head, the relative speed of the laser head with respect to the workpiece, the distance between the laser head and the surface of the workpiece, and the distance between the focal point of the laser beam and the surface of the workpiece. Laser cutting devices are also provided. | 02-06-2014 |
