Abstract: A seed treating and conveying apparatus includes an elongated auger unit on which a liquid chemical applicator tank is mounted for treating the seeds as they are conveyed through the auger tube. The auger includes a central shaft having brush flighting thereon for gentle handling of the seeds as well as for picking up treatment and thoroughly and uniformly applying it to the seeds. The auger unit is pivotally supported for adjusting the position of the discharge end without moving the vehicle on which it is mounted.

Abstract: A device for applying glue to the cut leading end of a veneer sheet which is applicable to use in a veneer jointing apparatus is disclosed herein. The device has hold-down means for holding the veneer sheet adjacent its cut leading end against a support surface on which a glue deposit is formed previously along a line across the veneer feeding direction, so that the end is straightened against said support surface at least while the glue is picked up by the cut surface on the moving leading end. It is so controlled that said holding means is shifted to its holding position before the cut leading end of the veneer sheet reaches the glue deposit and also that it is shifted away from the holding position only after the glue has been picked up by the cut leading end.

Abstract: A device for attachment to a conveyor of the auger type for supplying a liquid additive to a particulate material, such as seed grain, being transferred through the conveyor. The device includes a bracket for rigid connection to an outer casing of the conveyor, the bracket including upstanding arms between which is mounted a container for holding a supply of the additive. An additional member is clamped to the conveyor and provides an inlet to the interior of the casing, and a conduit connects an outlet of the container to the inlet member. A pivotal mounting between the container and the arms of the bracket allows the container to be moved to an upright position regardless of the angle of the conveyor.

The auger includes a central shaft having brush flighting thereon for gentle handling of the seeds as well as for picking up treatment and thoroughly and uniformly applying it to the seeds. The auger unit is pivotally supported for adjusting the position of the discharge end without moving the vehicle on which it is mounted. In one embodiment, the auger unit is mounted on a slide track so as to be both longitudinally and pivotally movable. In another embodiment, the auger unit is removable from the associated large seed hopper for use in filling the hopper.

Abstract: A liquid chemical treatment measuring device as for metering treated chemicals for agricultural seeds. A housing containing a disc-like rotor sandwiched between stationary discs or headers, there being flat faces between the rotary disc and the stationary headers or discs. A rotary disc has a multiplicity of measuring chambers extending endways through its thickness. The stationary discs have supply and recirculation manifold grooves opposite each other and confronting the measuring chambers of the revolving disc, and also an inlet port and an overflow port producing continuous flushing of the measuring chambers and supply and recirculation grooves. The stationary discs or headers also have discharge and relief manifold grooves opposite each other and draining the liquid chemical treatment from the measuring chambers of the revolving rotor and supplying air into the chambers to allow rapid draining.

Abstract: An apparatus for encapsulating magnetic particles by enclosure within oil drops, mixing in an aqueous solution and dispersing the oil drops with the enclosed particles by application of an alternating magnetic field. The dispersed and oil covered particles are microencapsulated with at least one type of polymer.

Abstract: To impregnate loose cotton staple and like fibers with chemicals, a mass of such fibers is fed into and through a series of compartments in a baffled housing assembly and is there acted upon by a series of cooperating rotating paddle assemblies while in contact with a chemical containing aqueous liquor at room temperature and atmospheric pressure. The paddle assembly initially produces, with the liquid, turbulent columns of bubbles within each of the compartments, with the result that the cotton fibers are located in the thin walls between the bubbles.

Abstract: Apparatus and a method for the selective conditioning, wetting and coating of particles with a selective wetting agent. The apparatus includes a horizontally extending surface capable of vibration which vibration induces uniform translatory movement along the surface to particles upon the surface. A vertically extending barrier is on the surface and extends across the surface and at right angle to the direction of movement of particles upon the surface. A means for spraying the selective wetting agent onto the particles as they move along the surface and before they reach the barrier is provided. Means for removing excess wetting agent are provided on the surface along the direction of movement of the particles after the barrier. A pool of the selective wetting agent forms behind the barrier upon the surface.

Abstract: Method and apparatus are disclosed for producing very uniform coatings of a desired material on discrete microsized particles by electroless techniques. Agglomeration or bridging of the particles during the deposition process is prevented by imparting a sufficiently random motion to the particles that they are not in contact with each other for a time sufficient for such to occur.

Abstract: An improvement in an apparatus for treating seeds or other particles with a liquid. The apparatus includes a receiving chamber for receiving particles and liquid, and means for conveying consecutive batches of particles and liquid to the receiving chamber. Liquid is metered in batches through a liquid metering means which includes a container and a cyclic container transport. The latter is responsive to the conveyance of batches of particles to the receiving chamber and cycles the container between a dip position in a supply of treating liquid and a dumping position in which a batch of liquid is conveyed to the receiving chamber. The transport orients the container in its dip position so as to drain the container when the level of treating liquid recedes below the container. The retention of treating liquid in the container when the apparatus is not in use is thus avoided.

Abstract: A system and apparatus for treating articles of variable size and shape is disclosed in the illustrative embodiment utilizing vibrating feeder bowls into which fluids are introduced for treating the articles simultaneously with their automatic advancement. The system is further adapted for various spacial dispositions in accordance with the area available. A particular system is disclosed for treating aluminum nails by continuous advancement through a succession of feeder bowls at which the nails are subject to cleaning, washing, coating and rinsing.

Abstract: An elongated impregnator chamber is provided with superposed trough and rotating auger means which are positioned to be below the surface of an activating solution that will be introduced into and retained in the chamber during impregnating operations. The counter-rotation of the auger means in the successive superposed troughs will provide for a relatively rapid continuous movement of particles through the impregnator chamber and, in turn, provide improved efficiency in comparison to batch impregnations. Chamber discharge is through a conduit communicating with the lowermost trough and extending upwardly above the solution level in the chamber.

Abstract: Small workpieces to be coated with plastic material are preheated and dropped onto a fluidized bed of plastic powder subjected to compound vibratory motion which causes the powder and the workpieces to move along a helical ramp onto a screen overlying the point of entry, with some of the particles fusing onto the workpiece surfaces to form a film. The remainder of the powder, on reaching the screen, drops back onto the bed as the coated workpieces move on to a receptable. Fresh workpieces are deposited on the bed through one or more chutes traversing the screen; to prevent the rise of any particles through the chutes, a downward airflow is created therein.

Abstract: Method and apparatus for agitating an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material are disclosed. Movable vanes are disposed beneath the surface of a bath of the composition. The vanes have a relatively large surface area and are moved through the bath at low speed so that the shear stress imposed on the dispersed particles is minimized. This prolongs the stability of the composition.
