20100204945 | System and Method for Detecting Fluid Delivery System Conditions Based on Motor Parameters - Systems and methods for detecting various system conditions in a fluid delivery system (such as an HVAC system) based on a motor parameter are disclosed. Embodiments of the present invention relate to detecting: filter condition, frozen coil condition, register condition, energy efficiency, system failure, or any combination thereof. Embodiments of the present invention relate to detecting fluid delivery system conditions based on motor parameters including system current, system power, system efficiency, motor current, motor power, motor efficiency, and/or a change (or rate of change) in motor parameters. Techniques for responding to a clogged filter and a frozen coil are also disclosed. Also disclosed are techniques for characterizing a fluid delivery system off-site, prior to system installation. | 08-12-2010 |

20100143738 | Process for Producing Biopolymer Nanoparticle Biolatex Compositions Having Enhanced Performance and Compositions Based Thereon - The present invention provides novel biolatex conjugate compositions and methods of production and use thereof. The novel biolatex conjugate compositions comprise a biopolymer-additive complex (prepared by co-extruding a biopolymer feedstock, at least one performance-enhancing additive, and at least one plasticizer under shear forces) reacted with a crosslinking agent under shear forces. The biolatex conjugate compositions exhibit enhanced performance properties for coated paper, paperboard, and other applications using extremely low levels of performance-enhancing additives. | 06-10-2010 |
20110042841 | PROCESS FOR PRODUCING BIOPOLYMER NANOPARTICLES - A process for producing a biopolymer nanoparticles product is disclosed. In this process, biopolymer feedstock and a plasticizer are fed to a feed zone of an extruder having a screw configuration in which the feedstock is process using shear forces in the extruder, and a crosslinking agent is added to the extruder downstream of the feed zone. The biopolymer feedstock and plasticizer are preferably added separately to the feed zone. The screw configuration may include two or more steam seal sections. Shear forces in a first section of the extruder may be greater than shear forces in an adjacent second section of the extruder downstream of the first section. In a post reaction section located after a point in which the crosslinking reaction has been completed, water may be added to improve die performance. | 02-24-2011 |
20130062807 | PROCESS FOR PRODUCING BIOPOLYMER NANOPARTICLES - In a process for producing a biopolymer nanoparticles, biopolymer feedstock and a plasticizer are fed to a feed zone of an extruder and the biopolymer feedstock is processed using shear forces. A crosslinking agent is added to the extruder downstream of the feed zone. The process has a production rate of at least 1.0 metric tons per hour. The feedstock and the plasticizer are preferably added separately to the feed zone. The extruder may have single flight elements in the feed zone. The temperatures in the intermediate section of the extruder are preferably kept above 100 C. The screw configuration may include two or more steam seal sections. Shear forces in a first section of the extruder may be greater than shear forces in an adjacent downstream section of the first section. In a post reaction section, water may be added to improve die performance. | 03-14-2013 |
