Abstract: A wood burning stove is provided. The combustion chamber in which the fire occurs has a baffle plate that is moveable to direct air flow through one of two different pathways from the combustion chamber to the chimney. When in a first position, the baffle plate forces the air and smoke to move through a first pathway; when in a second position, a by-pass pathway is opened, allowing air and smoke to move through a second pathway. The stove can have a door in the front wall, or the top wall, or both walls, to provide access to the combustion chamber.

Abstract: An automatic air intake control includes a timing mechanism that regulates the amount of air entering a combustion chamber enclosure during combustion of a fuel. The amount of air is regulated to provide an efficient and clean burn of a solid fuel. The control may include a cover, an actuating assembly, and a controller. The cover is movable between open and closed positions relative to an air passage opening into the combustion chamber enclosure. The actuating assembly is coupled to the cover and configured to move the cover between the open and closed positions. The controller is coupled to the actuating member and configured to control the position of the cover through the actuating member to regulate the air intake into the combustion chamber. The controller may be a time-based device such as a timer, or may be any other device that uses inputs associated with the combustion of fuel in the combustion chamber or a user's preferences for the characteristics of combustion in combustion chamber.

Abstract: A method for sensing and controlling the weld quality of gas metal arc welding employs sampling of the welding current and voltage signals and making determinations of the weld quality state based on information embedded in those signals. The signals are processed such that the quality of the weld can be determined and the appropriate steps are taken to respond to the detected quality level. If the quality level is deemed unacceptable the process is terminated and the operator is alerted. The method includes determinations based on the standard deviation of the electrical signal, the summed power spectrum of the electrical signal, and/or the average absolute value of the time derivative of the electrical signal.
