An exhaust system of an agricultural product container includes a first media screen configured to be coupled to the agricultural product container. The first media screen includes a first plurality of apertures. The first media screen is configured to block a granular product from entering the exhaust system and enabling an air flow into the exhaust system. The exhaust system includes a diffuser having a first diffuser aperture configured to diffuse the air flow in a downward direction. The exhaust system further includes a passage fluidly coupled between the first media screen and the diffuser. The passage is configured to selectively guide the air flow from the first media screen toward the diffuser.

Provided is a polycarbonate resin powder, including a polycarbonate-polyorganosiloxane copolymer, in which an amount of particles each having a particle diameter of 300 m or less in an entirety of the powder is 60 mass % or less.

The here present invention introduces a method and a device applying said method for the separation of a primarily heterogeneous material stream, as commonly encountered in the waste management industry. The device primarily constitutes a housing which features a cylindrical component, into which a gas stream is introduced by means of a gas injection nozzle, which passes through the material stream, which contains individual fractions at least once. Due to the specific curvatures of the cylindrical housing part and the specific arrangement of several flow control elements as well as the associated interaction of the undisturbed laminar gas/material stream with the separation of the individual fractions in the interior of the housing, a compact design of the device as well as a high degree of separation can be achieved.

A method and a dense phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or the like installation for spraying coating powder are disclosed. In order to reduce the number of components of the dense phase powder pump that require maintenance, the dense phase powder pump is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber for conveying coating powder.

A seed metering system includes a volumetric meter and a plurality of row units. Each and every one of the plurality of row units includes a singulating meter, a bypass conduit, and an outlet that is common to and downstream of the singulating meter and the bypass conduit. The seed metering system further includes a dispersion unit including an inlet and a plurality of outlets and operable to disperse the plurality of seeds from the volumetric meter to the plurality of row units. The seed metering system is operable in a first mode of operation in which the volumetric meter communicates with each singulating meter via the dispersion unit to singulate the plurality of seeds. The seed metering system is operable in a second mode of operation in which the volumetric meter communicates with each bypass conduit via the dispersion unit such that the plurality of seeds are not singulated.

A method and system for conveying material in a pneumatic material conveying system includes a material input point, a material conveying pipe connectable with a feed-in container, the system being configured to provide a pressure difference in the material conveying pipe that includes a partial-vacuum generator, and a separator device in which the transported material is separated from the transport air at an outlet end of the material conveying system. The material is conveyed in a first stage from the input point to a conveying pipe, into a container space of an intermediate container arranged between the input point and the separator device by a suction/pressure difference provided by the partial vacuum generator in a first time period, and the material conveyed into the container space of the intermediate container is conveyed by a suction/pressure difference provided by the partial-vacuum generator to the separator device.
