Granted: 1997-03-15
Abstract: The fomenter has the excellent effects on recovery of fatigue, skin cosmetics, solution of stress and prevention of various disease such as adult disease. Such effects are caused by excreting a various of waste materials resulting from the promoted blood circulation and vigorous metabolism. On using, one should sit or lie down on the plate(8) heated to suitable temperature by heater(31). If so, the functional power generated from each layer permeates deeply to the body so it perform its function. At the same time, the fomenting action is produced by the heated plate and infrared ray. Consequently, the capillary is extended and circulation of blood is promoted by augmentation of cell molecule movement, with much sweat being excreted. Therefore, the fomenter assists to excrete a various of waste material, a harmful material in the body, and residual heavy metals with sweat, and to activate metabolism.

Abstract: PCT No. PCT/CA91/00006 Sec. 371 Date Jan. 21, 1993 Sec. 102(e) Date Jan. 21, 1993 PCT Filed Jan. 8, 1991 PCT Pub. No. WO92/00152 PCT Pub. Date Jan. 9, 1992.This invention pertains to a method and apparatus for reclaiming gypsum from waste paper laminated gypsum wallboard. The invention is directed to an apparatus that is useful for separating paper laminate from gypsum wallboard comprising: a roller and a plate spatially disposed from the roller. The aperture between the roller and the plate is sized to be slightly less than the wallboard thickness thereby creating a fracturing action between the gypsum and the paper laminate. The first roller can be driven by a power source. A roller can be substituted for the plate and can be undriven or driven independently of the first roller.
