20120298012 | Admixtures for Shrink Crack Reduction of Portland Cement-Based Mortars and Concretes - Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC). | 11-29-2012 |

20120097050 | DYNAMIC CONTROL SYSTEM AND METHOD FOR CONTROLLED ATMOSPHERE ROOM - A control system for a controlled atmosphere room (“CA room”) for storing perishable commodities, such as fruits and vegetables. The control system includes an enclosure that can be placed within the CA room to store a representative sample of the commodities in the CA room. The control system includes an atmosphere valve selectively operable to provide atmospheric communication between the enclosure and the CA room or to isolate the enclosure from the CA room. The control system includes a sampling control system for determining a dynamic control value based on the isolated representative sample. The dynamic control value may be determined by monitoring the respiratory quotient in the enclosure while it is isolated. Once determined, the control system can use the dynamic control value to adjust the atmosphere of the CA room, thereby using tests on a representative sample to control the atmosphere for the full volume of commodities in the CA room. When not testing, the enclosure generally remains in atmospheric communication with the CA room, which improves the correlation of the representative sample with the commodities in the CA room. | 04-26-2012 |
20120325086 | SYSTEM AND METHOD OF OPERATION FOR CONTROLLED ATMOSPHERE STORAGE - A nitrogen-flush scrubber system for a controlled atmosphere room in which the amount of nitrogen required to flush the regenerated scrubber beds is significantly reduced. The present invention provides a dual-bed scrubber system in which low oxygen air salvaged from the active scrubber bed is used to flush high oxygen air from the regenerated scrubber bed prior to nitrogen flush. The scrubber system may include two scrubber beds that are used alternately to scrub air from the CA room. One scrubber bed is used as an active scrubber bed to remove carbon dioxide from the air. The inactive scrubber bed may be regenerated while it is inactive. When the active scrubber bed becomes sufficiently saturated, the control system may switch the active scrubber bed, using the regenerated bed as the active scrubber bed and allowing the saturated bed to be regenerated. Before switching, the regenerated bed is purged to reduce the oxygen level, which increased during regeneration. First, a volume of low oxygen air is salvaged from the active scrubber bed. The low oxygen air may be salvaged by moving it back into the CA room or into a storage reservoir, such as an air bag. The salvaged low oxygen air may then be moved into the regenerated scrubber bed to reduce the oxygen content in that bed. After the low oxygen air has been introduced into the regenerated scrubber bed, a nitrogen purge process may be used to further reduce the oxygen content in the regenerated scrubber bed. Once the desired oxygen level is reached, the regenerated bed may become the active scrubber bed. | 12-27-2012 |

20130259610 | SYSTEM AND METHOD FOR GAPPING CONVEYED SUBSTRATES - A method for gapping substrates conveyed through a vacuum chamber is disclosed. The method may include positioning an upstream substrate outside the vacuum chamber as a downstream substrate is conveyed within the vacuum chamber, detecting a position of the downstream substrate within the vacuum chamber and conveying the upstream substrate into the vacuum chamber at a conveyance rate greater than a conveyance rate of the downstream substrate to set a gap between the downstream substrate and the upstream substrate. | 10-03-2013 |
20130306620 | HEATING SYSTEM AND METHODS FOR CONTROLLING THE HEATERS OF A HEATING SYSTEM - A method for controlling a plurality of heaters of a heating system is disclosed.

20140354145 | VOLUMETRIC LIGHT EMITTING DEVICE - A volumetric light emitting device includes a substrate, a semiconductor light emitting diode disposed on the substrate and a reflector ring extending axially from the substrate. The reflector ring defines a first volume bounded by the substrate, an inner wall of the reflector ring, and a terminal plane at a distal end of the reflector ring. An encapsulant fills the first volume and encapsulates the semiconductor light emitting diode. A volumetric light conversion element surrounds the reflector ring and the first volume wherein the volumetric light conversion element is adapted to down-convert light emitted from the semiconductor light emitting diode at a first wavelength and emit the down-converted light at a second wavelength. A second volume of encapsulant or scattering material extends axially between the terminal plane and the volumetric light conversion element. | 12-04-2014 |
