Patent number: 7708886Abstract: Method and apparatus in which a biomass is carried on a substrate that is fluidised. The fluidised substrate has a layer of distributor particles below it, through which the fluidizing medium passes prior to contact with the fluidised substrate and biomass associated therewith. The effect of the distributor layer is that the particles damp out excessive turbulence in the fluidizing medium, thus preventing undue turbulence of the medium within the fluidised layer. The particles may be recycled through the distributor layer to strip excess biofilm from the substrate particles prior to returning the substrate particles to the fluidised bed.Type: GrantFiled: December 17, 2007Date of Patent: May 4, 2010Assignee: Advanced Bioprocess Development LimitedInventor: Michael John Dempsey

Patent number: 7309433Abstract: Method and apparatus (8) in which a biomass is carried on a substrate which is fluidised. The fluidised substrate has below it a lazer of distributor particles through which the fluidising medium passes prior to contact with the fluidised substrate and biomass associated therewith. The effect of the distributor layer is that the particles damp out excessive turbulence in the fluidising medium thus preventing undue turbulence of the medium within the fluidised layer. This has the advantage of controlling, to some extent, the thickness of the biofilm, which may be carried by the fluidised substrate particles. The particles may be recycles (1, 2, 5) through the distributor layer where the action of the distributor particles serve to strip exces biofilm from the substrate particles which latter are then returned to the fluidised bed.Type: GrantFiled: October 9, 2002Date of Patent: December 18, 2007Assignee: Advanced Bioprocess Development LimitedInventor: Michael John Dempsey

Publication number: 20070046063Abstract: A traffic collision cover is disclosed which restricts the view of physical damage to one or more vehicles involved in a traffic accident to passing motorists and pedestrians who may slow down and obstruct traffic while observing an accident scene. This invention allows emergency personnel to quickly cover one or more vehicles or parts of vehicles with fabric to hide the damage done in an accident. As a result, this invention helps prevent traffic congestion and increase traffic flow at accident scenes.Type: ApplicationFiled: August 26, 2005Publication date: March 1, 2007Inventor: John Dempsey

Patent number: 6572773Abstract: The present invention concerns the field of nitrification of fluids, and particularly relates to the treatment of aqueous fluids to oxidize ammonia and nitrites to produce nitrates. One aspect of the present invention seeks to provide an alternative nitrification process which is readily capable of commercial implementation, and in which the nitrification rate more nearly approaches the rate of ammonia generation. According to one aspect of the present invention there is provided a microbiological process for the nitrification of a fluid comprising passing the fluid to be nitrified through an immobilized biomass comprising nitrifying bacteria, characterised in that the bacteria are immobilized as a biofilm grown on porous particles, in particular coke.Type: GrantFiled: June 29, 2001Date of Patent: June 3, 2003Assignee: The Manchester Metropolitan UniversityInventor: Michael John Dempsey
