Abstract: A feeding mechanism for a round hay baler is capable of feeding plastic sheet, netting, or alternatively twine by means of a single set of parallel feed rolls. The device includes a control mechanism which, upon sensing of a full bale having been formed within the baler, initiates a programmed control sequence beginning with driving of one roll for an incremental period of time. The driven roll engage netting, sheet or twine against the second idler roll and feeds the netting, sheet or twine into the bale forming mechanism for wrapping about the bale. Upon completion of the wrapping sequence, a special knife descends and cuts the twine or sheet of netting or plastic. The controller then resets the mechanism.

Abstract: A concurrent-countercurrent air flow grain dryer of the type having an enclosed bin with a wet grain inlet at the top and a dry grain outlet at the bottom includes means for introducing hot air near the top of the bin to serve as a drying medium for the grain in a flow concurrent with the grain. Means are provided at the bottom of the bin to introduce cool air which flows countercurrent to the grain flow. An exhaust is provided intermediate where the hot and cool air are introduced. A manifold for the exhaust directs parts of the exhaust air through the hot air inlet portion of the dryer. In this manner, at least a portion of the exhaust air is recycled prior to ultimate exhaust from a vent associated with the exhaust manifold.

Abstract: A turbocharger especially for marine engines includes a dual chamber block interposed between the carburetor and the turbocharger. The block includes a first chamber for receipt of a fuel air mixture and a second chamber separated by a heat transfer wall from the first chamber. The second chamber receives hot water from the cooling system of the engine and effectively directs heat through the heat transfer wall to prevent condensation of fuel from the fuel air mixture in the first chamber. Consequently, it is possible to use a rich air fuel mixture and maintain the mixture in a vaporized state to prevent premature detonation and deterioration of the engine.
