Patent number: 9796849Abstract: A process for preparing polyurethane composites includes (i) providing a dispersion of nanocrystalline cellulose in (a) one or more polyols, (b) one or more isocyanates, or (c) one or more polyols and one or more isocyanate, mixed together; wherein the amount of water in the nanocrystalline cellulose is less than about 1% w/w; (ii) mixing the dispersion of (i)(a) with an isocyanate or (i)(b) with a polyol and a catalyst to allow polymerization; or mixing the dispersion of (i)(c) and a catalyst to allow polymerization; and (iii) isolating the polyurethane composite. A method for improving properties of polyurethanes includes dispersing nanocrystalline cellulose into one or both parts of a two part polyol/isocyanate precursors prior to allowing polymerization of the precursors, wherein the amount of water in the nanocrystalline cellulose is less than about 1% w/w; mixing the dispersion with a catalyst; and polymerizing the precursors to provide the polyurethane.Type: GrantFiled: May 22, 2014Date of Patent: October 24, 2017Assignee: Celluforce Inc.Inventors: Richard Berry, Alain Granger

Patent number: 7715718Abstract: Optical Time-Domain Reflectometer (OTDR) troubleshooting of a passive optical network (PON) can be enhanced by deploying cascaded splitters, at least some of which have multiple inputs. That is, at least some of the splitters in the PON have not only a first input coupleable to the optical line terminator (OLT) or output of another splitter but also a second input directly coupleable to an Optical Time-Domain Reflectometer (OTDR). Optical time-delay reflectometry can be performed upon a selected portion or segment of the PON by selecting a splitter and transmitting an optical test signal from the OTDR directly to the input of the selected splitter and analyzing the reflected signal.Type: GrantFiled: August 1, 2006Date of Patent: May 11, 2010Assignee: Alcatel LucentInventors: Joseph Lee Smith, Alain Granger

Patent number: 7660409Abstract: A multi-dwelling unit (MDU) module is configured for providing telephony communicating services and non-telephony services. The MDU module includes a motherboard and a plurality of service units connected to the motherboard. Each one of said service units and the motherboard are jointly configured for providing non-telephony service and telephony service to a plurality of service subscribers. The motherboard is configured for providing overload power management to limit power consumption associated with said telephony services during an overload condition and for providing lifeline power management to limit power consumption associated with said non-telephony services during a power outage condition. The MDU module optionally includes lightning primary surge protection blocks configured for being connected to the service units.Type: GrantFiled: December 30, 2004Date of Patent: February 9, 2010Assignee: Alcatel LucentInventors: Richard Marion Czerwiec, Manal Afify, Atahan Tuzel, Barry Lee Moffitt, Joseph Lee Smith, Anthony Peter Noto, David Charles Fargo, Bobby Lane English, John David Boyle, Alain Granger, Jak Yaemsiri, Andreas Flach, John Scott Cao, Ali Rezaki, Charles Pearse, Bakri Aboukarr, Arkin Aydin, Angelo Arlotta, Nicholas Adam Bundza

Patent number: 3979284Abstract: An artificial haemodialysing kidney and method of operation in which the haemodialyser has one chamber connectable to a blood stream and another chamber on the opposite side of its membrane forming part of a constant volume closed vessel for dialysis liquid. The system can be operated as a closed circuit during which time a fraction of the dialysis liquid is withdrawn from the constant volume closed vessel at a desired flow rate and the reduction in pressure then existing in the vessel near the membrane is noted. The system is then switched to open circuit with the dialysis liquid being fed from a source thereof and the used liquid is dumped, the pressure during this period being adjusted to the noted value.Type: GrantFiled: March 21, 1975Date of Patent: September 7, 1976Assignee: Rhone-Poulenc S.A.Inventors: Alain Granger, Andre Sausse

Patent number: 3939069Abstract: A method of ultrafiltration and an artificial kidney therefor, in which a membrane which is capable of simultaneous ultrafiltration and dialysis of blood is arranged to form a portion of the wall of a constant volume, closed loop vessel. A dialysis liquid is circulated in the vessel, while blood is passed on the opposite face of the membrane, and a fraction of the dialysis liquid is withdrawn from the vessel at a predetermined rate. The remainder of the dialysis liquid is kept at a constant temperature and is regenerated.Type: GrantFiled: December 6, 1972Date of Patent: February 17, 1976Assignee: Rhone-Poulenc-TextileInventors: Alain Granger, Andre Sausse
