Abstract: A control system for a fuel-burning appliance such as a wood or pellet burning stove may include a particulate matter sensor. The control system may also include an ignition system to ignite an ignition charge of ignitable fuel. A processor controls the operation of the functional components of the appliance to maintain operating conditions within pre-determined parameters.

Abstract: A press apparatus for forming molded products is provided and includes an motive source and a press assembly in fluid communication with the motive source. The press assembly includes a press plate and a device configured to actuate axial movement of the press plate as initiated by the motive source. A mold base is positioned within the press assembly and configured for engagement with the press plate. The mold base includes a plurality of mold cavities and each of the mold cavities includes a mold cavity aperture. Each of the mold cavity apertures is arranged in a pattern and configured to provide access to a molded product positioned in a mold cavity. A release assembly is configured for engagement with the mold base and has a plurality of release fingers, each extending from a base plate. The plurality of release fingers is arranged in a pattern that aligns with the pattern of the mold cavity apertures.

Abstract: A method and controller compensates control variables of a continuous process prior to the control variables being input to the controller/control matrix to at least partially mask the effect of a selected disturbance or a manipulated variable on that controlled variable to the controller. The controlled variable(s) has been chosen to be an inference of a desired underlying or related variable which is not directly measurable. The selected disturbance to be masked is one which does affect the (measured) controlled variable, but not the underlying desired variable. By at least partially masking the effect to all intents and purposes the controller is unaware of the effect of the selected disturbance on the controlled variable and therefore, for a fully masked disturbance, does not make any adjustment to a manipulated variable associated with the selected disturbance which would unnecessarily alter the underlying desired variable.
