Abstract: A hand-held tool for not only placing granular materials such as grass seed, granular chemicals, or a combination thereof into soil but also aerating it and detecting near surface rocks and the like. The tool includes a hopper, a shaft which terminates in a soil-piercing spike, and a spring-actuated sleeve slideably mounted on the shaft. The shaft defines a partially hollow bore and an orifice, the orifice being disposed on a sidewall of the shaft distal from the hopper and proximate with the juncture between the shaft and the spike. The bore and the orifice fluidly communicate with each other and with the hopper. The spring-actuated sleeve normally blocks the orifice, so that seed and/or chemicals cannot spill out of it. Granular materials are dispensed by dropping them by gravity out of the orifice whenever the spike can be driven into the soil far enough.

Abstract: A lubricant dispenser comprising a housing, a lubricant supply container, a plunger, a telescopic hollow spindle, and an electromechanical servo-drive for changing the length of the telescopic hollow spindle. One end of the telescopic hollow spindle is fixed on the housing. With its other end, the telescopic hollow spindle cooperates with a plunger containing a passage opening for lubricant. The telescopic hollow spindle has a lubricant passage channel in which at least one check valve is arranged on the inlet side. The telescopic hollow spindle alternately carries out setting strokes of different lengths that increase or reduce the length of the spindle. The setting strokes are coordinated with each other so that with a setting stroke of the telescopic hollow spindle increasing the length of the spindle, a preset amount of lubricant displaced by the movement of the plunger enters the lubricant passage channel through the opening check valve.

Abstract: A product distribution system includes a cone shaped member for receiving a mass of solid flowable product thereon and a pair of concentric downwardly extending cylindrical walls. A top portion of the first of the downwardly extending cylindrical walls is adjacent to and abutting the base of the cone shaped member. A plurality of circularly arranged electromagnetic feeders which extend outwardly in a radial direction from the cone shaped member are disposed below the cone shaped member at the bottom of the first cylindrical wall, and in close proximity thereto, for moving product away from the first cylindrical wall and toward a plurality of circularly arranged weigh hoppers. The second cylindrical wall or retaining member has a diameter which is greater than the first cylindrical wall and together with the first wall forms a circular trough at the base of the cone shaped member.

Abstract: A dome-shaped pressurized can contains a foil sack for holding a substrate, which is positioned in the can cylinder, whose upper edge is fastened in a welt connecting the can cylinder with a dome cover. The upper edge of the foil sack is clamped between the inner wall, the double cylinder and an adjacent edge of the dome and the clamped edge of the foil sack has a diameter which is larger than the diameter of the adjoining sack cylinder and rests on the inside of the can cylinder.

Abstract: A skirt board and mounting arrangement to seal the side edges of a conveyor belt to prevent the escape of material being conveyed. The skirt board sections include a pair of opposed side faces, one of which is placed against a mounting surface. One of the faces includes a specially constructed engagement surface which is operative, when engaged by a stop to permit the skirt board to be adjusted downwardly toward the conveyor belt but prevents the skirt board from moving upwardly away from the belt. A clamp secures the skirt board against a mounting surface.

Abstract: Apparatus for feeding wood chips and the like into a treatment bin includes a feed tube assembly adapted to lead into the bin at a non-zero angle relative to the horizon. A plate is supported underneath the lower end of the feed tube assembly to collect in a mound wood chips fed through the feed tube. The height of the lower end of the feed tube assembly is adjusted so that the lower end of the feed tube assembly engages the mound of wood chips and thereby forms a seal with the mound. A plow is supported between the plate and the lower end of the feed tube assembly. Either the plate is stationary and the plow rotates or the plow is stationary and the plate rotates to knock wood whips from the mound off the plate. The apparatus optionally includes a feed screw mounted within and longitudinally of the feed tube assembly to compress the wood chips into the mound.

Abstract: Apparatus for feeding granular material into a gas stream, for example seed or fertilizer into multiple airstreams of an agricultural vehicle, includes a receptacle for granular material, a duct for a gas stream, and a pair of resiliently compressible surfaces which contact or almost contact to define a nip between them. The surfaces may be provided by contrarotatable rollers and are disposed so that granular material may pass from one side of the nip through a port into the duct, and are moveable into the nip from the other side. The apparatus further includes metering means defining a controllable outlet from the receptacle and positioned with respect to the nip for feeding granular material into the nip from said other side at an adjustable controlled rate. Also disclosed is a distributor for gas-entrained granular material which includes a conical, part-conical or inverted conical surface in a diverging housing.

Abstract: An apparatus for the precise dispensing of particulate matter either at a uniform flow rate or in repetitious accurately measured discrete batches. The apparatus includes a housing having a hopper with a hopper outlet orientated over an endless conveyor belt. A metering tube is connected to the hopper outlet and is movable toward and away from the upper surface of the forward run of the conveyor belt. The distance of the lower end of the metering tube from the conveyor belt provides one measure of regulation of flow rate of the particulate matter from the hopper to the conveyor belt. The speed of the conveyor belt provides a second measure of regulation of the rate of flow from the hopper to the conveyor belt and eventually to a dispensing station.

Abstract: A dispenser for an aqueous solution of a chemical, such as potassium permanganate, that should be confined at all times encloses the chemical in a lightweight disposable jar. The dispenser is actuated by a valve that has a relatively large float on one end of a stem and a diaphragm at the other end of such stem. It is not necessary for the user of the chemical to ever remove it from the container in which it is sold.
