    Abstract: A respiratory gas analyzer system and apparatus for medical purposes is provided. The system includes a thermal conductivity cell for measuring the amount of carbon dioxide in a sample of a subject''s expired air. The system also includes a computer which periodically calculates and provides a digital display of the carbon dioxide production in the expired air. The latter computer also calculates and digitally displays the ratio of carbon dioxide production to oxygen depletion in the expired air, which is known as the ''''respiratory quotient''''.

    Abstract: An exercise treadmill is provided for diagnostic and therapeutic purposes, which includes, among other features, an eddy-current, variable speed drive to obtain a belt speed range from zero to maximum speed, and a differential drive through a slip clutch to the two rollers imparting motion to the belt. Safety of the subject is enhanced by an electrically non-conductive coating on the handrails to eliminate any possibility of grounding electricity through the patient''s body. Incorporation of a chair as an integral part of the assembly assures a rest place in appropriate proximity to the walking surface. The treadmill walking surface is positioned and maintained at the desired inclination with minimum apparatus load by virtue of locating the fulcrum at approximately the center-of-gravity. The inclination is displayed on a remote control panel which also provides the capability of controlling all functions of the unit. Regardless of what inclination the treadmill walking surface is positioned at, the chair positioned proximate thereto is, in one embodiment thereof, maintained level with the floor on which the treadmill is supported.

    Abstract: A boom structure including a plurality of crossed links having their centers and ends pivotally connected to define a lazy tong structure includes a compression spring positioned to exert a force between the next to last and last links making up the lazy tong structure when the structure is in collapsed position to aid extension of the structure. The spring has one end secured close to the central point of the next to last link and its other end is free. The opposing last link portion includes a guiding cone for receiving the free end of the compression spring when the structure is collapsed. When the lazy tong structure is extended, the compression spring effects initial extension of the next to last and last links while the initial crossed links at the base of the boom are separated by the driving force for extending the structure. A smooth unfolding of the respective links can thus be realized.
