Abstract: There is disclosed a thermoelectric device suitable for drying gases in which a finned heat-dissipating device is in contact with the hot face of a thermoelectric element and a thermal sink is in contact with the cold face thereof. The thermal sink has formed therein a conduit which zig-zags from an inlet at the upper part thereof to a point at the bottom thereof and then upwardly to an outlet at the other side. The conduit is formed by routing out a channel in a block and sealing it off with a face plate to provide the desired conduit. The various elements are held together by face plates spanning the heat-radiating device and the thermal sink, and the space between the two is desirably filled with insulating material. The device is used in combination with a gas analyzer in which exhaust gases, for example, from an internal combustion engine, are fed through the dryer and then into the analyzer.

Abstract: A square base with upright side walls and a flat top wall defining a large circular opening has an upstanding ring spaced concentrically around the opening. A cylindrical hood open at the bottom fits within the ring and is pivotally connected to the top of the base. A pair of fluid pressure operated cylinders with piston rods are connected to opposite sides of the base and the hood to swing the hood about its pivot to open position above the base. A work supporting grid is supported within the base below the ring. A tank is connected to one side wall of the base, and an inclined collector plate located in the base below the grid drains to a hole opening to the top of the tank. Liquid delivery couplings connected to the top of the hood and the top of the collector plate centrally thereof with fixed cylindrical outlet housings projecting toward the inside of the hood have receiving connections on their ends located outwardly of the hood and plate.
