Abstract: A device for assisting invalids into and from a seated position, e.g., over a toilet. The device has a frame and a seat hingedly attached at the front thereof to a support member which is vertically slidable on the frame. A stop is associated with the hinge to prevent the seat from pivoting below the horizontal attitude. An extendable arm is connected at one end to the frame and, at the other end thereof, to the seat between the hinge and the center of gravity. Control means selectively activates extension of the arm to initially vertically elevate the seat in the horizontal attitude, and then to pivot the seat upwardly to assist an individual seated thereon into a standing position; or activates retraction of the arm to initially pivot the seat into a horizontal attitude, and then to vertically lower the seat in a horizontal attitude to assist an individual into a seated position.

Abstract: Wood burning stove having several features for reducing emissions output and for improving energy efficiency by increasing the supply of oxygen to combustible materials, by increasing the mixing of oxygen with combustible materials, and by lengthening the residence time of combustible materials within the stove. The features include a turbulence-creating means positioned at an upper, front region of the combustion chamber, and a baffle located near the outlet for increasing both turbulence and the pathway of combustible materials exiting the stove.
