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: Improved barbecue and kabob skewers are described. The barbecue skewer includes a rod or brochette to support, warm and cook food and a structure that allows for easy and effective removal of food when served. As an additional feature of the remover may include a safety guard to protect fingers, hands and arms from burns. The remover may also include a brush or tough material to scrape and clean the skewer. Further, the remover may be attached to a skewer handle for storage and convenience or may be separately applied for use.

Abstract: A method and apparatus for providing the wearer of a typical safety helmet, face shield, or other headwear a mirror system that improves the wearer's awareness of the rear and side ambient environment. A display is provided to the wearer of a safety helmet that encompasses a reverse field of view and an extended side view of the surrounding environment. This system not only compensates for the limited peripheral view of the helmet but also extends the wearer's visual perception.
