In one aspect, a system for removing blockages present within a delivery conduit of a seeder may include a plurality of delivery conduits, a plurality of flow blocking devices, and a plurality of blockage sensors. A controller may be configured to determine when a blockage is present within a first delivery conduit of the plurality of delivery conduits based on measurement signals received from the plurality of blockage sensors. The controller may be further configured to control the flow blocking devices to occlude the flow of air through the other delivery conduits of the plurality of delivery conduits such that an air pressure in the first delivery conduit is increased.

A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.

A continuous production system continuously produces a product from a raw material powder. The system includes a first processor that performs a first process on the raw material powder, a second processor that performs a second process on the powder on which the first process has been performed by the first processor, and a test chamber through which the powder being sent from the first processor to the second processor passes. A cleaner blows gas from an inlet side opening formed in the inner face of a channel connected to the test chamber from the first processor on the downstream side of an inlet side gate valve for opening and closing the channel toward a direction to form a swirling flow along the inner face of the channel.

A method and a device for transporting a plurality of insects from a chamber to a location via a channel, wherein the insects are transported by means of an apparatus for producing a medium flow, and wherein a transport additive is added to the medium flow during transport, the amount of the transport additive being set in accordance with the amount of insects moved.

A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

A method to manufacture a tubular element for transferring abrasive materials such as concrete, inert materials or suchlike, wherein the tubular element comprises an internal tubular component made of chromium carbide or other wear-resistant material, and an internal tubular component in contact with and coaxial to the internal tubular component and made of composite material.

An auto-fill two-layer two-half wear resistant elbow of a concrete pump truck consists of an outer-layer protection elbow, an inner-layer heterogeneous wear resistant combined elbow and a wear resistant connecting flange. A filling space is provided between the outer-layer protection elbow and the inner-layer heterogeneous wear resistant combined elbow. The wear resistant elbow is designed as a two-layer two-half unique structure including a protection layer and a wear resistant layer. Upon using the wear resistant elbow for the first time, the concrete grout fills the reserved slit via the heterogenous combined elbow and enters the reserved filling space, allowing the outer-layer protection elbow and the inner-layer heterogeneous wear resistant combined elbow to be fixed as a whole.

The present invention is directed to an applicator having an agricultural product mechanical and/or pneumatic conveying system which transfers particulate material from one or more source containers to application equipment on demand, and meters the material at the application equipment. The conveying system includes a static distributor interconnecting the supply lines of the conveying system with the distribution lines connected to the individual nozzles. The static distributor includes internal structures that effectively divert the incoming particulate material evenly across the interior of the static distributor such that the particulate material is evenly distributed into each of the distribution lines. The static distributor accomplishes this without the need for any moving parts or control systems/devices. In addition, damage done to the particulate material flowing through the distributor is not high, and the operation of the distributor creates a lower pressure drop across the distributor than prior art vertical distributors.

A module connector for holding and/or transporting of bulk goods for connecting a first container module to a second container module, the container modules being joined together have an aligned container inner surface, a first seal arranged between the first container module and the second container module, a second seal arranged between the first container module and the second container module, the first seal is arranged in a recess and the second seal in a groove, the first seal forming an inner seal and the second seal forming an outer seal, the second seal produces a sealing of the interconnected container modules especially if the first seal fails, the first seal has at least one crimp region, which is crimped by a first and/or second flange surface such that one end face of the first seal is situated flush and/or aligned with the container inner surface without forming a cavity in the area of the end face of the first seal as well as a seal element for the module connector for the sealing of the container.
