Abstract: A semi-automated wood-cutting machine includes a receiving/alignment stage adapted to receive a piece of wood, the receiving/alignment stage having an alignment aid adapted to facilitate manual alignment of the piece of wood, and a cutting stage spaced from the receiving/alignment stage, the cutting stage being configured to cut the piece of wood along a predetermined cut pathway.

Abstract: A process of removing off-flavors and off-odors, such as caused by TCA, from food or beverage products by contacting the food or beverage with one or more aliphatic synthetic polymers so as to sufficiently lower the concentration of the off-flavors and off-odors that they are undetectable by taste or smell.

Abstract: Various burner configurations for combustion of a particulate fuel such as sawdust, and many types of varying moisture content biomass fuels such as poultry litter. The burners exhibit a high turndown ratio. the burners include a housing defining an upright combustion chamber lined with refractory material and generally circular cross section, a main combustion region within an upper extent the combustion chamber, an initial combustion zone at a lower end of the combustion chamber of reduced-size cross-section compared to the combustion chamber and a transition region increasing in cross-section from the initial combustion zone to the main combustion region. A principal fuel (e.g., sawdust) is supplied with combustion air to the initial combustion region, and an auxiliary ignition fuel supplies heat to the initial combustion region for igniting the principal fuel.

Abstract: A combustor system provides high temperature, high-dwell combustion of emission products, as from charcoal kilns, with inner and outer combustion chambers. Multiple inlets receive emission products from multiple heat exchangers omnidirectionally extending for continuous heat exchange connection between the combustor and emission sources. Hot products of combustion are delivered to each heat exchanger, each with multiple ducts in mutual heat exchange relationship including at least a hot products of combustion duct for receiving at the proximal end hot products of combustion from an outlet of the outer chamber, and conveying the hot products of combustion to the distal end at a respective emission source, an emissions inlet duct for receiving emission products at the distal end from the emission source, and a return products of combustion duct for receiving at the distal end the hot products of combustion and returning them to the combustor.
