A seed metering gate assembly (12) is provided for use with an upright seed bin (10) having a shiftable primary gate (24), wherein the gate assembly (12) provides an additional seed flow control function allowing more accurate dispensing of seed from the bin (10). The gate assembly (12) includes a seed hopper (13) equipped with a fore and aft-shiftable metering gate (42) movable between a closed position and an open position presenting a seed output passageway (40). Apparatus (62) is operably coupled with the gate member (42) in order to determine the travel of metering gate member between the fully closed position and a plurality of open positions presenting respective, differently sized passageways (40). The apparatus (62) preferably includes a rod (64) having a series of through openings (70) and coupled with the gate member (42), with a shiftable, motion-limiting collar (72) mounted on the rod (64) and securable at any of the openings (70) by a clip (76). The opening movement of the rod (64) is limited by engagement between the collar (72) and a bracket (68) affixed to hopper (13).

An assembly for selectively supplying particulate material to an air seeder, an agricultural implement able to selectively supply and dispense particulate material into the ground and a method of selectively dispensing particulate material into the ground are provided. The assembly has at least one supply receptacle for receiving particulate material from a source and a metering roller for supplying the material to an air seeder. The assembly is operative to selectively supply the material to the air seeder and prevent the material from being supplied to the air seeder. The implement can use the assembly to selectively supply particulate material to ground engaging openers where the particulate material will be dispensed into the ground. Particulate material can be selectively supplied to the implement when it is desired to have the particulate material dispensed into the ground and then prevented from being supplied to the implement when it is not desirable.

A product-on-demand delivery system for an agricultural machine having a main hopper arrangement wherein each outlet nozzle of the main hopper nozzle manifold is connected to plural product hoses that are each in communication with an auxiliary product hopper of an application unit. The nozzle manifold includes an inlet for receiving pressurized air, and an outlet nozzle allowing air with entrained seed or product to exit the main hopper. The outlet nozzle includes a splitter portion, such as a Y-shaped fitting, having a single splitter inlet and two splitter outlets. The single splitter inlet is coupled to a nozzle portion of the outlet nozzle and the two splitter outlets are coupled to two product hoses that are each coupled to a respective application unit. An internal divider wall extends through the nozzle portion and partially through the splitter portion from the splitter inlet to the splitter outlets. The divider wall evenly divides flow of air and entrained seed or product between the two splitter outlets to the two application units.

A product-on-demand delivery system applies an agricultural product, such as seed, to a field. The system includes a frame that mounts a main hopper, a splitter fitting, a primary product hose, a secondary product hose, a primary application unit and a secondary application unit. The main hopper has an air nozzle wherein an air stream through the air nozzle entrains product within the air stream and delivers the air / product to the primary outlet hose. The splitter fitting has a splitter inlet flow-connected to the primary product hose and two splitter outlets flow-connected to the application units. The secondary application unit is coupled to the primary product supply hose by the secondary product hose connected at an outlet branch. The outlet branch is connected at an angle such that a product flow velocity vector in the primary product supply hose at the outlet branch is at an obtuse angle to a flow velocity vector of product flowing through the outlet branch. The outlet branch is oriented for a vertical upward flow of air and product.

An unmanned helicopter has a fuselage (1a) with a main body (4) and a tail body; a main rotor (6) provided above the main body (4) and driven by an engine in the fuselage (1a); a tail rotor placed at the rear of the tail body (5); a pair of left and right support legs (8,8) extended downward from lower left and lower right sections of the main body (4); a pair of left and right skids (9) provided at lower ends of the support legs (8,8) and positioned, in a front view, more on the outside in the width direction of the fuselage (1a) than the main body (4); and a radiator (71) positioned, in a side view, more on the front side than the front edges of the skids (8) and formed so as to extend downward from the vicinity of a bottom surface (83) of a main body front section so that an airflow receiving surface of the radiator is oriented in the front-rear direction of the fuselage (1a). Outer edges, in the width direction of the fuselage (1a), of the radiator (71) are projected outward, in the front view, from outer edges of a main body bottom surface (83) near the radiator (71). Also, outer edges (71a) of the radiator (71) are positioned more on the inside, in the width direction of the fuselage (1a), than the skids (9).

A row crop unit for use in an agricultural seeder includes a furrow opener for opening a furrow in the soil, a seed metering system for metering seed to be placed in the furrow, and a seed placement system for placing seeds in the furrow. The seed placement system and the seed metering system are in communication with each other and at least in part define a seed travel path associated with the furrow. A furrow closer covers the seed in the furrow with soil. A seed temperature conditioner is associated with the seed travel path for varying a temperature of seed traveling through the seed travel path. A temperature sensitive sensor is positioned to sense seed which has been deposited in the furrow between the furrow opener and the furrow closer. An optional packaging tube holds a temperature sensor or sensor array. A lens is mounted with the same tube. A larger diameter tube may be positioned around the sensor packaging tube. A positive air pressure / air flow may be introduced between the two tubes. This positive air-flow forms a positive pressure and / or air flow barrier to push dust away from the sensor lens or sensor surface.

A pistol-shaped powder delivery device consolidates propellant pulse creation, powder storage, powder aerosolization and aerolsolized powdered delivery in a single device while providing dose, pattern and coverage control of the output spray. The single-hand-held, single-hand-operated device includes a housing having a handle portion that is selectively collapsed to generate a propellant pulse that is conveyed into and through powder stored in a reservoir mounted at an upward angle to the horizontal in a receptacle provided in the housing. Powder in the reservoir is caused to be aerosolized by the propellant pulse whereupon aerosolized powder exits the reservoir through an open end of, and elongate slots provided in the sidewall of, an elongate hollow member extending from an outlet in the receptacle through the stored powdered material into a head space in the reservoir. The outlet is connected a barrel portion for output of the aerosolized powder spray.
