Abstract:
A system (10) for de-icing aircraft (12) in a de-icing area includes a first recessed storage area (24) located substantially below ground level on a first side of the de-icing area. A first spraying boom (22), having at least one boom section, is used to apply de-icing solution to surfaces of aircraft (12). A first spray nozzle (64), for applying de-icing solution to surfaces of aircraft, is supported by the first spraying boom (22). The first spraying boom (22) may be raised out of the first recessed storage area (24) when an aircraft needs de-icing and lowered into the first recessed storage area (24) for storage when aircraft de-icing is complete.

Abstract:
A drying system includes a fluidized bed dryer and fluidizing gas loop. The system is a closed loop so that fluidizing gas used to dry particulate matter can be reconditioned and recycled to fluidize and dry additional particulate matter. The fluidizing gas is reconditioned by removing fine particulates and water vapor. The drying system includes oxygen control features to prevent oxygen from entering the system. A method for drying particulate matter includes fluidizing the particulate matter in a dryer with a fluidizing gas, heating the particulate matter to remove water, removing water vapor and fluidizing gas from the dryer, removing fines and water vapor from the fluidizing gas, recirculating the fluidizing gas to the dryer to fluidize additional particulate matter and removing dried particulate matter from the dryer. A modular drying system reduces the amount of construction necessary at the installation site.
Abstract:
A system for replacement of abrasive (152) in machinery which uses the abrasive to finish the surfaces of workpieces that pass through the machinery on a belt, such as so-called widebelt sanders. One preferred embodiment of the system employs an abrasive material (152) that is frictionally held on each edge to mounts (210, 220). The position of the mounts may be varied to increase or decrease the tension of abrasive material against the working surface of the platen (100), that the assembly may he removed from the apparatus. In another embodiment, the abrasive material is formed with integral, permanent mounts (320) on the edges of the abrasive material, so that the entire combination may be supplied or replaced as a unit. A variety of configurations of mounts may be used.
