  • Patent number: 10791727
    Abstract: An agricultural implement has a product supply chamber, and a pair of transversely extending product delivering booms, each with a plurality of conduits of varying lengths terminating in product distributing nozzles. A fan supplies air to a mixing chamber which also receives product from the supply chamber providing an air entrained flow of product to each conduit. A controller monitors product delivery and controls implement operation. Each conduit has a pressure tap near the nozzle for providing the controller with a pressure differential indication. The controller initiates a corrective action modifying the operation of the delivery system when a predetermined pressure differential threshold is exceeded. The corrective action may include an increased air flow volume, an additional burst of higher pressure air into the conduit, a temporary increase in air flow from the air flow source, or a reduction in the rate of product flow from the supply chamber.

  • Patent number: 10774719
    Abstract: A side feed inlet port for an injector, which makes use of stamped parts to form a compact, high strength three-piece inlet port at a significantly reduced cost. By using an inner sleeve and an outer sleeve, injector sealing is accomplished using the interior sleeve, creating a sealing point, while allowing for inlet conduit attachment to the outer sleeve at, above, or below the sealing point of the DEF injector. The construction of the inlet port is such that there is proper sealing between the inner sleeve and one or more seals, while allowing for the connection between the inlet conduit and the outer sleeve to reduce the overall height of the inlet port, and therefore, the injector. The position of the inlet conduit may be altered without affecting the sealing connection between the inner sleeve and the seal(s), such that the desirable overall height may be achieved.
