20140093396 | COMPRESSED GAS PRODUCTION AND CONTROL - A method and apparatus for producing and controlling flow rate of a compressed gas produced by a compression system having one or more stages of compression formed by a centrifugal compressor or compressors, inlet guide vanes to control flow through the compression stage or stages and an electric motor directly coupled to the stage or stages having a restricted speed zone within which vibrational modes can damage the electric motor. A desired flow rate is obtained by speed adjustment alone and with the inlet guide vanes positioned at 0° when the speed will lie above or below the restricted speed zone. Where a desired flow rate would require extended operation of the electric motor at a speed within the restricted speed zone, the speed is set to the uppermost level of the restricted speed zone and the desired flow rate is obtained through appropriate positioning of the inlet guide vanes. | 04-03-2014 |
20150377244 | SYSTEM AND METHOD FOR COMPRESSING AIR - A compression train system and method for compressing air for an air separation unit is provided. The system includes at least one initial air compressor configured to receive and compress a flow of ambient pressure air and driven by a variable speed motor. The system further includes a plurality of downstream compressors or compression turbo-machines disposed in a series arrangement with the at least one initial compression stage. The desired flow rates to the compression system is controlled by adjusting the speed of the variable speed motor and the position of inlet guide vanes to increase or decrease the flow rate of the ambient pressure air and keep the speed of the variable speed motor above or below a restricted speed zone. | 12-31-2015 |

20160032934 | METHOD FOR COMPRESSING AN INCOMING FEED AIR STREAM IN A CRYOGENIC AIR SEPARATION PLANT - A method for compression of an incoming feed air stream using at least two variable speed compressor drive assemblies controlled in tandem is provided. The first variable speed driver assembly drives at least one compression stage in the lower pressure compressor unit driven while the second variable speed driver assembly drives higher pressure compression stage disposed either in the common air compression train or the split functional compression train of the air separation plant. The first and second variable speed driver assemblies are preferably high speed, variable speed electric motor assemblies each having a motor body, a motor housing, and a motor shaft with one or more impellers directly and rigidly coupled to the motor shaft via a sacrificial rigid shaft coupling. | 02-04-2016 |

20120278097 | Creating and Visualizing Professionally Crowdsourced Structured Medical Knowledge - A system and a method are disclosed for gathering and visualizing votes on the comparative efficacy, tolerability, and cost of medical treatments, including surgeries, drugs, devices, radiological and other procedures and interventions, using an Internet-based, credentialed physician social network. The system includes a method for intuitive head-to-head visualization of competing treatments, based upon aggregated community physician votes, with respect to their performance on the principal clinical dimensions of efficacy, tolerability, and cost. The system additionally includes a method to reduce intentional and unintentional voting bias. | 11-01-2012 |
20140129386 | COMPUTERIZED REAL-TIME VALUE SCORING OF VEHICLES - Systems and methods for real-time value scoring of automobiles are described herein. In one aspect, a criterion identifying a type of vehicle is received. A number of vehicles offered for sale are identified, based at least in part on the criterion. A metric indicating the relative value of each of the identified offers for sale is provided, based at least in part on the other identified offers. The identified offers are organized based at least in part on options included on each vehicle and the metric indicating the relative value of each of the identified offers. The organized identified offers are then provided. In some implementations, the relative value metric may be generated based at least in part on the other identified offers. | 05-08-2014 |
