| 20110067991 | THERMAL TREATMENT OF BIOMASS - A biomass pyrolysis process is provided in which biomass feedstock is mixed with a heat carrier. The heat carrier at least partly comprises char. The ratio by weight of biomass to char is in the range 1:1 to 1:20. The process may be carried out by in a screw/auger pyrolysis reactor in which the solid feedstock components are conveyed along the reactor by a first screw. A second screw conveys at least a portion of the solid products of the biomass pyrolysis back to a heat transfer medium input port. Thus, the heat transfer medium includes char from the biomass pyrolysis. | 03-24-2011 |
| 20110070628 | BIOMASS PROCESSIGN - A biomass processing system is disclosed, with an algae biomass growth container and a pyrolysis reactor for pyrolysis processing of the algae biomass. A conveying apparatus links the pyrolysis reactor and the biomass growth container for conveying at least part of at least one of the pyrolysis products from the reactor to the biomass growth container for promoting algae biomass growth. The pyrolysis product is a nutrient-rich aqueous phase produced directly or indirectly through pyrolysis processing to the biomass growth container, e.g. an aqueous phase derived from the vapour products of the pyrolysis, or a char wash obtained by washing the char product of the pyrolysis. | 03-24-2011 |

| 20110278149 | STAGED BIOMASS PYROLYSIS PROCESS AND APPARATUS - A biomass pyrolysis process in which biomass feedstock particles (having a d5o mean particle size of at least 1 mm) are thermally treated substantially in the absence of oxygen to pyrolyse the biomass feedstock particles. The thermal treatment of the biomass feedstock particles includes a heat treatment drying step at a temperature in the range 100° C. to 250° C. Then, at a pre-pyrolysis heating location in a heat treatment system, the biomass feedstock particles are heated to a temperature in the range 280° C. to 350° C., held within the same temperature range for a time of at least 5 seconds and then moved from the pre-pyrolysis heating location to a pyrolysis heating location by a conveyor system for heating to a temperature above 350° C. for pyrolysis. | 11-17-2011 |

| 20090099810 | METHOD FOR FAULT DETECTION IN AN ACTUATOR - A method for detecting fault in an actuator. By transmitting a control value, which is generated by a control unit, to an input of the actuator a signal for the measured actuator position is produced at the output of the actuator. The signal for the measured actuator position is sent to an input of a signal conditioning unit which determines from it a measure of actuator movement. The control value is also transmitted to an input of a modeling unit, which calculates from it an expected measure of actuator movement. These movements are sent to a computer unit, which produces a corresponding status signal for the functionality of the actuator and for the functionality of the sensor for determining the actuator position. | 04-16-2009 |
