The pointing device tracks movement of the two hand wheels and communicates the movement to a control system which controls a moveable element. The contact is made long enough so that it makes contact at each end with a metal layer, but design rule spacing is still maintained between the connections with the metal layer. The architecture provides for fault-tolerant, transparent interaction of components and services and supports a variety of standards for each level of the open systems interconnection layers and layers of TCPIP. The feed screw is rotated to convey the cellulose pulp in the transverse direction through the distributor housing.
