Abstract: This invention is for boosting the performance of any existing rockpile-type sauna generator by dividing the rockpile to two parts, the lower part for steam generation and the upper part for steam drying and superheating. The parts are separated from each other by an enclosed space, clear of rocks, which allows water to spread out onto a large area of the rocks at the lower part the rockpile and steam to expand into a large space below the top part of the rockpile and thus to touch a large volume of hot rocks when it rises through the rockpile. Water is transported down to the space above the bottom part of the rockpile without touching the hot rocks at the top of the rockpile, by using bypassers which allow water to run down past the upper part of the rockpile and to spread out over a large area of rocks at lower part of the rockpile.

Abstract: A dryer has an internal drying chamber for accommodating articles that are subjected to heated circulating air to remove moisture from the articles. An air mixing chamber contains a first fan for moving air through a heater into the drying chamber. A second fan draws air out of the drying and mixing chambers and discharges air back into the mixing chamber through a filter into the external environment. The heated air in the drying chamber is mixed with fresh air and recirculated through the drying chamber to minimize heat losses and increase drying effectiveness. Ultraviolet lamps within the drying chamber destroy contaminants in the air and articles within the chamber. A boot dryer, located in the drying chamber, has fans that move air through tubes used to support boots, shoes, skates and socks. Ultraviolet light in the boot chamber destroys contaminants in the air in the boot chamber. One modification of the dryer has a bench to permit the dryer to be used as a dry sauna.

Abstract: A shower PUVA apparatus has a reservoir within which a medicinal solution may be placed.
