Apparatuses and systems for and methods of generating and placing zero-slump-pumpable concrete
11766807 · 2023-09-26 ·

Methods, systems, and devices, are developed for in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement.

Method for mixing a stream of particulate material by inducing backflow within an inclined belt conveyor

An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.

20220016585 · 2022-01-20 ·

A vortex generator device in channels or ducts that makes it possible to take advantage of the wingtip vortex that is formed in the aerodynamic profiles as a consequence of having a finite wingspan. These aerodynamic profiles have one or two marginal edges from which the wingtip vortex emerges, causing the appearance of an oscillatory movement that subjects the particles that travel with the current to an ascending-descending cycle, and has the fundamental advantage that transverse speeds are produced to the main current, with hardly any pressure drops.

Methods for Maintaining a Metered Flow Rate of Fluid Treated Seed

A stream of seed may be maintained at a metered flow rate through multiple stages of a treatment process. These multiple stages include dispensing, first application of fluid, second application of fluid, and seed transport. Seed transport may be accomplished through a conveyor configured to maintain the metered flow rate while providing static mixing, drying, and conditioning of the treated seed. The metered stream of seed may be treated within a first treatment applicator where a first wet treatment is applied, transferred through the incline conveyor, and treated again within a second treatment applicator where a second wet treatment is applied. Overtreating in multiple stages may layer consecutive seed treatments around the treated seed. A predetermined amount of seed treatment may be applied to the coated seed based on the metered flow rate established. Maintaining the metered flow rate through multiple stages eliminates the need for multiple metering steps.
