    摘要: A delivery fan includes a plurality of blades defining a fan pocket for receiving a signature. The plurality of blades includes two sets of blades. The blades of one set are axially equally spaced apart and define one side of the pocket. The blades of the other set are axially equally spaced apart and define the other side of the pocket. The blades of both sets of blades have surfaces for engaging opposite sides of the signature and for deforming the signature into undulations extending in a direction transverse to the direction of movement of the signature. While the signature is being engaged and deformed, the frictional contact between the signature and the surfaces in the pocket slows down the signature. This minimizes buckling and/or bouncing of the signature in the pocket.

    摘要: A forced air furnace comprises an enclosure, an adjusting mechanism, an interface, an electric heating element and a fan. The enclosure has an air inlet and an air outlet. The adjusting mechanism is operative to adjust the air outlet between an open position and a partially closed position. The interface is located proximate to the air outlet and is used to connect the air outlet to a duct. The fan is powered by an electric motor. Both the fan and the electric heating element are located inside the enclosure. There is also described a method of installing a forced air furnace. The method comprises the step of adjusting a size of an exhaust area of an air outlet of the forced air furnace in order to produce a desired exhaust airflow through the exhaust area when the forced air furnace is connected to a ductwork.
