A talc applicator is provided for use with agricultural equipment such as grain carts and seed tenders. The talc applicator includes a supply hopper with a trough, a discharge, a feed auger extending through the trough and discharge, and an agitator assembly positioned in the supply hopper immediately above the feed auger and trough. The agitator assembly includes a drive gear driven by the drive element of the feed auger and an elongated agitator element including at least two elongate bars and a plurality of angled crossbars connecting the two elongate bars. The agitator element rotates to assist with flow of talc into the trough so that the feed auger can move the talc to the other agricultural equipment. The talc applicator may also be provided with a hydraulic motor and a flexible flighting in the feed auger.

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.

An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO.sub.2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO.sub.2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO.sub.2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO.sub.2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO.sub.2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.

A powdering system, having a working configuration and a cleaning configuration and including a powder reservoir, including a supply chamber receiving powder; a sprayer, including a powder applicator, and a cleaning inlet, fluidly connected to the supply chamber such that, in the cleaning configuration, a cleaning air supply source can be connected to the cleaning inlet so as to circulate cleaning air in the supply chamber, wherein the powder reservoir includes a discharge opening, arranged through a wall of the supply chamber and opening into the supply chamber, and a movable plug, which is movable between a closing position, in the working configuration, and an open position, in the cleaning configuration, such that the circulation of cleaning air causes residual powder to be discharged through the discharge opening.

A dry electrode manufacturing process employed for low cost battery through a dry mixing and formation process. A thermal activation renders the dry fabricated electrode comparable to conventional slurry casted electrodes. The dry electrode mixture results from a combination of a plurality of types of constituent particles, including at least an active charge material and a binder, and typically a conductive material such as carbon. The process heats the deposited mixture to a moderate temperature for activating the binder for adhering the mixture to the substrate; and compresses the deposited mixture to a thickness for achieving an electrical sufficiency of the compressed, deposited mixture as a charge material in a battery.

A dilute phase powder pump for pumping powder, particularly coating powder, from a powder reservoir to a powder spray-coating device, includes a powder inlet, which is or can be flow-connected to the powder reservoir, and a powder outlet, which is or can be flow-connected to the powder spray-coating device. The dilute phase powder pump also has a powder pumping injector with a motive fluid nozzle and a converging inlet nozzle, and has a valve device for optionally interrupting a flow connection between the powder inlet (80) of the dilute phase powder pump and a powder inlet of the motive fluid nozzle.

A powder supply device includes: a hopper that stores powder; a tubular chute that extends in an axial direction, includes one end connected to a lower end of the hopper, and discharges the powder supplied from the hopper from a discharge port provided at an opposite end thereof; an auger screw that is rotatably provided in the chute and includes a helical blade for transporting the powder toward the discharge port; and at least one strip-shaped portion which is provided on an inner wall surface of the chute and has an elongated recessed or protruding shape and of which a longitudinal direction extends in a direction intersecting with at least a part of the blade.

The present invention relates to a method for distributing particulate material in a target area. The method comprises the steps of (i) providing in a reservoir particulate material comprising particles to be distributed in a target area, which reservoir is provided with exits, (ii) providing a gas displacer, (iii) generating with the gas displacer a forced gas flow in the blow direction, and iv) directing the particles from the exits in the forced gas flow. The invention further relates to a device for performing the method according to the invention. Further aspects of the invention relate to the use of the device for distributing particulate material, a gas flow modification device, the use of such modification device for modifying the gas flow in a device for distributing particulate material and a kit of parts comprising (a) the gas flow modification device and (b) a device for distributing particulate material.

At the rear end, the powder cup spray gun has an injector, a powder cup and a receptacle for the powder cup. The powder inlet of the injector is connected to the receptacle. The powder cup and the receptacle are designed in such a way that the powder cup can be fitted into the receptacle. In addition, a grip with a connection for conveying air, a connection for atomising air, and a connection for metering air is provided. The connection for the conveying air and the connection for the metering air are connected to the injector via lines running in the grip.
