Abstract: An apparatus for docking a portable data processing unit is provided in which a cylindrically shaped, pivotal support member is attached to a base member for supporting the portable unit. An interface card extends from a cavity within the support member and is configured to electrically and mechanically engage within a card interface slot of the portable data processing unit. In addition to providing an electrical interface between the docking apparatus and the portable data processing unit, the interface card provides a mechanical guide for guiding the portable data processing unit into the support member and provides additional support for the portable data processing unit when engaged within the cavity of the support member. The docking unit is tiltable relative to the base member to accommodate a suitable viewing angle.

Abstract: A method of controlling the particle size distribution in a fluidized bed reactor in which a primary bed of particulate material having a varying size and including fuel is established. Air is introduced into the bed to fluidize the material and promote the combustion of the fuel. A portion of the particulate material is discharged from the bed and into a secondary bed. Air is introduced to the secondary bed at a velocity sufficient to fluidize the particulate material and entrain some of the finer portions of the particulate material. The air and the entrained finer material from the secondary bed are passed back to the primary bed and the velocity of the air introduced to the secondary bed is varied to vary the amount of the finer material that is entrained and thus control the size of the material in the primary bed.

Abstract: A process for removing nitrous oxides from a gas, comprising the step of passing air through a bed of particulate material including a carbonaceous material to fluidize the material and promote combustion of the fuel and adding additional carbonaceous material to the bed. Additional air above the area of introduction of the air passes through the bed and passes the gas through the bed so that carbonaceous material scavenges the oxygen in the nitrous oxides.
