  • Patent number: 4176596
    Abstract: To form round bales of fibrous agricultural material, windrowed material is fed into a baling zone formed within a frame. The frame is formed of a stationery front part and a rear part pivotally connected to the front part. Circumferential peripheral surface of the baling zone is lined with conveying elements, either belts, chains, drums, rollers or the like can be used. The material enters in the lower portion of the front part through an opening between two adjacent conveying elements. As it is carried along by the conveying elements, the material is turned over on itself gradually producing a round bale limited in size by the circumferential periphery of the baling zone. As the zone becomes filled, the conveying elements compress the material, wherein the inner layers fold together in a stellate manner. When the bale is completed the rear part pivots away from the front part to discharge the bale.

  • Patent number: 4176637
    Abstract: A method and apparatus for mixing fuel and an oxidizing agent includes an electrically charged electrode which forms an electrostatic field through which a stream of fuel is passed so that the fuel particles become electrostatically charged and subsequently repel one another to disperse into and mix with an oxidizing agent and vaporize on contact with a heat source such as the wall surface of an intake manifold of an internal combustion engine or the walls of fuel burning apparatus, or combustion chambers of jet or rocket engines and the like. Fuel particles passing through the electrostatic field are charged by induction charging and in addition may also be electrostatically charged by direct contact with the electrode, which is provided with an open outlet end to permit a relatively unobstructed flow of intermixed fuel and oxidizing agent with a minimum of flow resistance and little possibility of ice formation.

  • Patent number: 4176642
    Abstract: A starting control for a fuel injected diesel engine retards movement of the fuel injection control rack out of the starting position by a degree which varies with temperature to improve the starting characteristics of the engine without interfering with normal operation of the fuel injection system and its control rack. Movement of the control rack out of the starting position in response to the increasing force exerted by the governor on the control rack coupled floating lever of the fuel injection system is resisted by a damper in the form of a dashpot having a plunger coupled to the floating lever. The dashpot may be coupled to the floating lever by a pivotable crank and a pair of magnets respectively mounted on the crank and the floating lever, the magnets eventually separating to remove the starting control from the fuel injection system when the opposing forces of the governor weights and damper become great enough due to increased engine speed or when the crank reaches an adjustable limit stop.
