Patent number: 8516968Abstract: A fluidized bed is described and which includes a multiplicity of fluidizing manifolds positioned in spaced relation one relative to the others; an enclosure positioned in gravity receiving relation relative to the multiplicity of fluidizing manifolds and which has an intake and a discharge end, and wherein particulate matter received in the fluidized bed moves under the influence of gravity from the intake end to the discharge end, and a moveable gate is mounted on the second discharge end of the enclosure and which is operable to selectively occlude a discharge aperture and which further facilitates the selective removal of particulate matter and waste material entrained with same, and which moves under the influence of gravity to the discharge end thereof.Type: GrantFiled: March 29, 2010Date of Patent: August 27, 2013Assignee: Outotec OyjInventors: LeRoy B. Pope, Michael L. Murphy, James M. Scranton, James R. Thomas, Peter Mohr, Ben H. Cosby, Michael E. Tracey, Mark R. Castle, Douglas W. Scrafford, Greg Dahlstrom

Patent number: 7509914Abstract: A folding leg apparatus for an article of furniture having a top and a support leg movable between an extended and a folded position comprises a mounting plate configured for attachment to the top of the article of furniture and including a pair of mounting flanges extending along opposite sides of the mounting plate, an upper pivot rod attached to the support leg adjacent the top end, a first pivoting connection between each end of the upper pivot rod and a corresponding one of the pair of mounting flanges and a second pivoting connection between the support leg and a corresponding one of the pair of mounting flanges offset on the support leg from the upper pivot rod. A latch mechanism is provided that includes a pair of pivot arms, each pivotably mounted to a corresponding one of the pair of mounting flanges and positioned between the flanges. Each of the pivot arms includes an actuator plate positioned between the flanges and adapted to be manually pressed.Type: GrantFiled: March 7, 2006Date of Patent: March 31, 2009Assignee: Ditto Sales, Inc.Inventor: Michael L.

Patent number: 6972114Abstract: A biomass gasifier apparatus (10) produces low BTU gas from biomass, while removing the char and ash in an efficient manner. A fluidized bed gasifier cell (20) receives biomass fuel from a fuel input system (280). A preferred fluidized bed gasifier cell includes a vertically oriented cylindrical enclosure. A layer of bed material (40), typically having a consistency similar to sand, is carried at the base of the enclosure. A plenum (60) supplies hot compressed gas to a plurality of parallel manifolds (80), each of which support a number of nozzles (100). Gas released by the nozzles fluidizes the bed, catalyzing the process of gasification of the biomass, while a low oxygen environment prevents excessive combustion. A bed change-out system (120) removes waste introduced into the fluidized bed gasifier with the biomass. Gas discharged from an upper portion of the fluidized bed gasifier includes low BTU gas that is the desired output of the system.Type: GrantFiled: February 16, 2001Date of Patent: December 6, 2005Inventors: LeRoy B. Pope, Michael L. Murphy

Patent number: 6276306Abstract: An apparatus (10) for recovering hydrocarbons or other volatile material from granular solids includes an infeed conveyor (20) that moves the mud, containing a mixture of particulate solids and hydrocarbons, into the fluid bed (40). The fluid bed fluidizes the mud; i.e. transforms the mud from a first condition wherein it is a mass having a consistency with elements of similarity with oatmeal, to a second condition wherein it is a mass of swirling particles. Some of the particles leave the fluid bed through a slide gate at the bottom. Other particles, gas and the hydrocarbons leave the fluid bed through an opening at the top, and are transferred to one or more cyclones (60). In the cyclones, the rapid circular motion of the gas, hydrocarbons and particles results in the particles hitting the inside surface of the cyclone, sliding downwardly, and leaving the cyclone through a slide gate.Type: GrantFiled: August 3, 2000Date of Patent: August 21, 2001Inventors: Michael L.

Patent number: 5101742Abstract: A continuously operable fluidized bed vessel system and method for incinerating and disposing of materials which produce high tramp residue. The system is particularly effective in combusting shredded tires and disposing of large amounts of wire tramp without requiring down-time for cleaning. Emission of undesirable gases is controlled by a sensing and controlling system which provides for automatic injection of combustion by-product-modifying gases and solids. Further control of undesirable gas emission is controlled by employing sealed combustible material input and solid waste output ports. Fluidizable bed material which is entrapped and discharged with the other residue is separated from magnetic tramp and larger grain sized non-magnetic tramp and recycled to continuously replenish the fluidized bed.Type: GrantFiled: June 28, 1991Date of Patent: April 7, 1992Assignee: Energy Products of IdahoInventors: Norman K. Sowards, Michael L. Murphy
