20130309873 | METHOD OF SELECTIVELY ETCHING A THREE-DIMENSIONAL STRUCTURE - A method of selectively etching a three-dimensional (3-D) structure includes generating a plasma in contact with the 3-D structure, and illuminating a designated portion of the 3-D structure with a laser beam while the plasma is being generated. Nonilluminated portions of the 3-D structure are etched at a first etch rate, and the designated portion of the 3-D structure is etched at a second etch rate, where the second etch rate is different from the first etch rate. | 11-21-2013 |

20140162465 | PLASMA SHIELD SURFACE PROTECTION - Apparatuses and methods are provided for electrostatically inhibiting particle contamination of a surface of a process structure, such as a mask or reticle. The apparatuses include a plasma-generating system configured to establish a plasma shield over the surface of the process structure. The plasma shield includes a plasma region and a plasma sheath over the surface of the process structure, with the plasma sheath being disposed, at least partially, adjacent to the surface of the process structure, between the plasma region and the surface of the process structure. The plasma shield facilitates negatively charging particles within the plasma shield, and electrostatically inhibits negatively-charged particle contamination of the surface of the process structure to be protected. | 06-12-2014 |

20150273251 | FIRE SACK - The present invention provides a fire sack for the quick and safe extinguishing of household, office, retail, commercial, and medical appliance and device fires. The fire sack includes an outer layer of sturdy canvas and an inner layer of fire-retardant material, preferably wool fire blanket material. The fire sack has two or more handles to assist in quickly placing the fire sack over a burning, smoking, melting or flaming appliance, and one or more drawstrings to quickly close the fire sack around a burning, smoking, melting or flaming appliance. The fire sack can be used to transport the device or appliance to a safe location, and avoids the mess and potential damage of fire extinguishing liquids or foams. | 10-01-2015 |

20110067368 | FILTER ARRANGEMENT AND METHODS - A filter element includes a single seamless media pack having first and second opposite ends and first and second lateral sides extending between the first and second ends. The media pack also has pleats extending between the first and second ends and a first cross-section defined between the first and second lateral sides. The first cross-section having at least one outward projection that defines an internal radius of at least ¼ inch wherein a plurality of pleats of the media pack are fanned around the internal radius. A first end cap is secured to the first end of the media pack while a second end cap secured to the second end of the media pack. Additionally, a frame member is secured to the first end cap, second end cap, the first lateral side, and the second lateral side. A pre-filter is usable with described filter arrangements. | 03-24-2011 |
