20160113415 | ICE MERCHANDISER - An ice merchandiser for storing bagged ice for purchase by a customer is provided. The ice merchandiser includes a housing defining a cavity and an opening, wherein the opening provides access to the cavity of the ice merchandiser. The ice merchandiser also includes a door that is movable between a first position and a second position, wherein in the first position the door covers the opening and in the second position, the door is positioned away from the opening such that the cavity is accessible. The ice merchandiser further includes an ultraviolet lamp located in the cavity of the ice merchandiser. | 04-28-2016 |

20120267830 | Method of rapid sintering of ceramics - Rapid sintering techniques for densifying zirconium dioxide based ceramic materials employing electromagnetic induction heating or inductive coupled plasma, reducing processing time from hours to minutes. In one embodiment a water-cooled coil is connected to a radio frequency power supply. The coil surrounds a susceptor body which in turn surrounds the ceramic to be sintered. The susceptor heats up in response to a magnetic field emanating from the coil as the coil receives electric power. The heat in turn is radiated from the susceptor and heats the ceramic. In another embodiment, the coil is connected to a radio frequency power supply of sufficiently high frequency and power to establish a plasma in the gas which surrounds the ceramic. The plasma then heats the ceramic. The method is especially useful for sintering ceramic dental appliances, in minutes which can lead to in situ fabrication of such appliances while a dental patient waits. | 10-25-2012 |

20110269618 | NANO-CRYSTALLINE DENTAL CERAMICS - Unlike conventional dental ceramic powder made by grinding, dental ceramic nanocrystals are formed by vaporization into individual particles. Tetragonal zirconia particles thus formed are not broken into pieces, and so do not transform to weaker monoclinic zirconia and weaker sintered products. The particles created by this approach can be much smaller, and dental prostheses sintered from this powder can be stronger and more realistic. For instance, the smaller size of sintered tetragonal zirconia crystals increases optical translucence by reducing scattering from birefringence, and the small average particle size and tight distribution of sizes and shapes can essentially eliminate pores in a sintered product. Cylindrical and spherical particles can be manufactured by this approach, whereas prior art dental ceramic particles were generally neither. In addition to tetragonal zirconia, various dental ceramic particles and powders can be made by this approach, which can be used to form various sintered dental prostheses. | 11-03-2011 |

20090095068 | SYSTEM FOR AND METHOD OF PROVIDING A WIDE-RANGE FLOW CONTROLLER - An improved flow measuring device, such as a mass flow meter or mass flow controller, providing a high turn-down ratio as compared to prior art devices. In accordance with various embodiments of the invention, a flow sensor includes a sensor flow path that includes one or more restrictions configured to provide the sensor flow path with a non-linear relationship between a pressure drop across the sensor flow path and the flow of fluid through the flow sensor conduit. Such a flow sensor preferably achieves a high turn-down ratio by way of a variable bypass ratio that is directly proportional to the sensor tube mass flow rate so that the turn-down ratio of the mass flow controller will be ideally proportional to the square of the turndown achievable by the flow sensor conduit fluid sensing portion alone. In some embodiments, the restriction can be employed as a part of a fluid seal having an orifice and disposed between a flow sensor portion of a flow meter and a bypass portion of the flow meter. | 04-16-2009 |
