An insulated, decorative hot drink cup for hot coffee or the like is provided which can be grasped and drunk from without fear that the user's fingers will be burned. The cup includes an inner, integral, synthetic resin cup member having a series of spaced, exterior, longitudinally extending, triangular in cross section ribs on the sidewall thereof, and an outer decorative paper overwrap permanently applied over and in contact with the ribs. This structure defines a series of discrete, juxtaposed, dead air chambers or cells in the cup assembly sidewall for maximum heat insulation, and the thermally minimal, essentially line contact between the rib apices and overwrap enhances this effect. An uppermost circumferential bead formed on the cup member provides a further seal and prevents passage of liquid between the overwrap and member sidewall.

A heat exchanger is mounted to the combine and receives waste heat from the combine engine. A blower is mounted to the combine and sucks ambient air through the heat exchanger to heat the air and blows the heated air into a closed end duct that has a portion mounted in the combine crop hopper. The portion of the closed end duct mounted in the crop hopper has a plurality of perforations therein so that the heated air can dry the combined crops. An apparatus is provided for controlling the temperature of the air blown into the combined crops including a damper for supplying a desired mixture of ambient air and heated air to the closed end duct. A transducer mounted in the closed end duct and a transducer responsive damper actuating apparatus moves the damper in response to the transducer response to the temperature of the air passing the transducer. The transducer responsive damper actuating apparatus is shown as a mechanical, pneumatic and electrical apparatus.
