Title: Heavy duty air filter with integral snow valve
Inventor: MACHADO JOSEPH
IPC: F02M31/06
Filed: 1990-01-22
Granted: 1999-06-01
Abstract: An air cleaner assembly for a motor vehicle includes and housing which carries a substantially flat valve cover plate which defines a pair of openings.  A valve is slidable relative to the valve cover plate through a linkage operated from the vehicle operator's compartment to cover one or the other of the openings in the valve cover plate.  During normal operation of the vehicle, combustion air is communicated to the air cleaner housing through the normal air induction system.  However, when heavy snow blocks  communication through the normal air induction system, the vehicle operator operates the linkage to move the valve to a position opening the other opening into the air cleaner, so that underhood air may be used for combustion as long as the normal air induction system is blocked by snow.

Title: Hot gas generation system for producing combustible gases for a burner from particulate solid organic biomass material
Inventor: MOREY NORVAL K
IPC: F23K3/14
Filed: 1991-12-19
Granted: 1997-10-14
Abstract: A bottom-feed, biomass material gasification system feeds fuel such as green and wet woodchips from below up through a central opening in a stationary, perforate fire table which supports the mound-like fuel bed which is formed.  A plurality of ring-like air manifolds contiguously below the fire table, and surrounding the fuel supply tube are separately provided with air in a controlled manner according to the demand for the combustible gas produced, and a greater volume of air is supplied to the centralmost manifold, than to the outer manifold, or manifolds.  The system includes, in addition to a primary heating chamber, a secondary heating chamber which receives the hot gases generated in the primary chamber and, via a centrifugal cyclonic action, combusts fly ash particles which may remain entrained in the gas, before passing the hot gases to the boiler burner for combustion.  The atmosphere in the primary combustion chamber is partially starved, insofar as the supply of oxygen is concerned, and is maintained under a lower pressure than the gases which outlet from the primary chamber to the secondary chamber so that there is a continuous suction or draft pulling the hot gases generated in the primary chamber directly to the secondary chamber.  An ash disposal system has paddles mounted on a rotary band bearing on the fire table for moving the ash which is generated from the perimeter of the fire table, when the ash build-up is sufficient to warrant it.
