20110161405 | INTELLIGENT NETWORK MANAGEMENT PLATFORM FOR IKVM SERVERS - An IP-based KVM (IKVM) switch system includes a plurality of control centers connected by a network via respective routers. A group of IKVM switches is connected to each router. Each IKVM switch is connected to a plurality of remote computers. Each control center stores system configuration information regarding all other control centers, including their IP addresses, port information, information about the IKVM switches managed by them, and (optionally) the remote computers connected to each IKVM switch. The control centers use a master-slave scheme to share the configuration information among them. When a client logs on to any control center, all IKVM in the system are displayed on a UI so that the client can select any IKVM or (optionally) remote computer for access. The control centers perform necessary functions to facilitate the access to the select IKVM or remote computer by the client. | 06-30-2011 |

20160046820 | METHOD AND COMPOSITE FOR PREPARING HEAT EXCHANGERS FOR CORROSIVE ENVIRONMENTS - The present invention provides application of perfluoroalkoxy (PFA) onto metallic substrates to form a pinhole-free protective layer by means of electrostatic powder coating, by adding highly thermally conductive fillers such as graphite or ceramic powders/fibers/whiskers/flakes into virgin PFA powder to improve the thermal conductivity, as well as the application of the filled PFA powder onto various metallic substrates, including convoluted or finned tubes, outer or inner surfaces. Using a simple powder coating technique, a pinhole-free protective layer thinner than a PTFE covering film and with much higher thermal conductivity is produced on the metallic tubes and a physical bond is created at the interface between the PFA and the tube. These make the overall heat transfer coefficient much higher than a PTFE covered tube, which must have a thicker PTFE film to avoid pinhole and is lack of physical bond at the interface. | 02-18-2016 |

20130264195 | PUMPLESS, FANLESS ELECTROLYTE-CIRCULATION SYSTEM - A pumpless, fanless electrolyte-circulation system comprises an electrolyzer core that generates hydrogen and oxygen gases and includes a water electrolyzer having a plurality of electrolytic serial clusters connected substantially in parallel with each other and assembled into respective sealed reaction cells. Each of the electrolytic serial clusters includes a plurality of electrolytic cells. An electrolyte container includes a plurality of electrolytes in form of a concentration and is substantially separated from and connected to the electrolyzer core with a supply tube and return tube. A frame is substantially resistant to the concentration and separates a plurality of electrodes. Releasing of the gases brings the electrolytes in the electrolyzer core out of the electrolyzer core through the supply tube into the electrolyte container. The return tube allows each of the electrolytes to enter the electrolyzer core such that the electrolyte is forced to circulate by a releasing force of the gases. | 10-10-2013 |

20090205795 | Combined process of peroxide bleaching of wood pulps and addition of optical brightening agents - A process for improving optical properties of high-yield pulp (HYP) for producing paper products with superior brightness. Optical brightening agents (OBAs) can effectively improve the optical properties of high-yield pulp (HYP). The present process involves incorporating the OBAs into the alkaline peroxide bleaching process. By combining peroxide bleaching with an optical brightening agent, one can decrease the bleaching cost to reach the same brightness target. Some key advantages of adding OBA to HYP at the pulp mill over the conventional wet-end addition of OBA include: i) the quenching effect on OBA by the wet-end cationic polymers such as PEI is decreased by fixing OBA on HYP fibers; ii) the negative impact of metal ions in the white water system on the OBA performance is minimized when OBA is pre-adsorbed and fixed on HYP fibers; iii) the photo-yellowing (color reversion) of HYP and HYP-containing paper sheets is decreased when more OBA is on HYP fibers to protect them from harmful UV radiation. | 08-20-2009 |
