Abstract: Various embodiments of the present disclosure provide techniques for enabling a user to efficiently design a programmable logic device (PLD) capable of partial reconfiguration. In some implementations, a processor is configured to run a system level design tool and accepts, as inputs from a user, an identification of at least two personas to be used within a reconfigurable region of the PLD. The design tool defines one or more boundaries of a partial reconfig (PR) domain, the PR domain including a partitioned reconfigurable region of the PLD that is selectably configurable as any of the at least two personas. In some implementations, the PR domain includes at least one IP component configured to safely shut down at least one signal, the at least one signal originating from or directed toward an element of the PLD outside of the PR domain.

Abstract: A charging device for charging a shaft furnace, including a rotary distributor and a variable drive for rotating the rotary distributor about an essentially vertical axis of rotation, where the rotary distributor includes a plurality of guiding members which form sliding channels for charge material, and where the rotary distributor comprises a junction slide from which each guiding member issues and which is arranged such that a flow of charge material slides via one specific guiding member in function of the velocity and/or the sense of rotation of the rotary distributor.

Abstract: A screw press separator is provided herein for separating and deliquifying a slurry of solids and liquids e.g., a slurry of manure and water, or any other slurry of similar physical characteristics. The separator includes a cylindrical housing having a slurry inflow port. A cylindrical strainer basket extends rearwardly from the housing for the passage of separated liquid therethrough. A cylindrical discharge chamber extends rearwardly from the outlet end of the strainer basket to define a solids discharge opening. A motor driven auger is disposed within the housing and the strainer basket, the auger including a shaft extending through the housing, through the strainer basket and through the cylindrical discharge chamber, for driving the auger for advancing the slurry rearwardly within the cylindrical housing. A spring-loaded door assembly which is connected to the shaft, is provided at the exit of the cylindrical discharge chamber.

Abstract: A gravity operated burner for particulate fuel. Fuel held in a hopper drops downwardly through a fuel tube to fall on an inclined chute. The chute feeds a shelf where burning takes place in a high heat zone. Material on the shelf stops unhindered flow of fuel down the chute.

Abstract: Apparatus for feeding solid waste material to one or more chargers of the type for forcing solid waste material into a furnace or boiler. An elongated auger housing is mounted above the chargers and includes a plurality of openings along its length and for depositing solid waste material into hoppers of the chargers. An auger is supported in the housing and conveys solid waste from one end of the auger housing to the other. A supply conveyor is provided for carrying a continuous supply of solid waste material to one end of the auger housing from a supply container. A return conveyor is positioned adjacent a discharge end of the auger housing and returns excess waste material to the supply container.

Abstract: There is disclosed a furnace for burning wooden wastes and, more specifically, sawdust and/or barks. The furnace is provided with an oil burner required for starting the fire. The draught from the oil burner fan is directed within a perforated box, located in the combustion chamber of the furnace, and the sawdust or the barks or other wooden particles fall, according to a measured flow, over the perforated box. The sawdust is first alighted by the oil burner flame, and combustion thereafter builds up thanks to the draught from the perforated box. This box draught comprises a vertically-upwardly-oriented vector, for alighting the wood particles before the latter reach the box, and a horizontal vector extending toward the interior of the furnace to force the burning particles away from the side wall of the furnace. The system includes measured flow feeding system for the sawdust and/or the bark, and having a pair of flap-doors to prevent the escape of smoke from the furnace.

Abstract: The disclosure herein describes a furnace for consuming solid fuel, such as wood, which comprises a gravitational feed chute for feeding the solid fuel in a combustion chamber; the chute has an open lower feed end adjoining the combustion chamber, the feed end being equipped with a plurality of flexible spaced retaining elements which serve to support the load of solid fuel in the chute; air nozzles are provided in the combustion chamber facing the feed end of the chute to create a circulation forcing combustion gases to pass through a zone of high temperature in the combustion chamber.

Abstract: The present invention relates to a fuel level indicator for a heating unit, such as a stove or furnace. In particular, the invention relates to an indicator for a wood burning heating unit with a grate which is slightly elevated when there is insufficient wood causing an electrical signal which may be used with a light or buzzer to indicate the need for fuel or with a conveyor automatically to feed fuel into the heating unit.
