Abstract: A loading system for light particulate materials. A storage hopper for granular material includes an airlock by which the material is fed into an air stream. The air and accompanying material are fed to a distribution pipe with multiple flexible downward projecting fill spouts which are spaced at regular intervals.

Abstract: A two-way pipe switch for bulk material includes a housing with an inlet port, a coaxial first outlet port connectable to the inlet port to define a first flow path and a second outlet port connectable to the inlet port to define a second flow path which rectangularly branches off the first flow path. Accommodated in the housing is a cock which is rotatable by about 120.degree. from a first position into a second position for selectively connecting the inlet port with the first and second outlet ports. The housing has a cylindrical inner wall which between the inlet port and the first outlet port defines a first area and between the inlet port and the second outlet port defines a second area, with each area being provided with a pocket-like recess facing the respective outlet port and including edges which cooperate with the respective end face of the cross piece in such a manner that bulk material particles are prevented from penetrating the respective sealing gaps.

Abstract: A device for closing a pipe branch, especially for closing either orifice of a Y-shaped distributor connection, which is to close the inflow of the unoccupied flow-off in a gastight and watertight manner, is proposed. At the same time, there will be the possibility of mixing the medium for all the connections. To achieve this object, for this purpose either branching-off junction connection is made closeable by means of a common rotary plug, the rotary plug being designed as an oblique cylinder section (see the drawing for this).

Abstract: A sorting method is disclosed in which particles suspended in a fluid are conducted in a closed duct and pass a measurement location in which particles to be selected trigger a signal by a sensing device. At a downstream fork, a pressure wave generated in response to the signal diverts the stream containing the particles from one branch to the other. An apparatus for carrying out this method is disclosed and includes a supply duct for the particle stream, a measurement duct, a measurement position in the measurement duct, a fork downstream of the measurement duct leading to a sorting branch duct and waste branch duct, and a pressure wave generator which is disposed in one of the ducts leading away from the fork.

A plurality of control elements is arranged in the passage, respective two of such control elements being situated between each adjacent two of the chutes. Each of the control elements has a substantially plate-shaped control member which is pivotally mounted at the bottom region of the duct, and a block member that extends substantially at a right angle to the control member remotely from the pivot axis and extends toward and into the respective chute. The control element can be pivoted into and arrested in any selected pivoted position, including a closed position in which the block member thereof substantially completely prevents the flow of the transporting medium past the same.

Abstract: Disclosed is a pipe divider for use in pipes intended for conveying solids of small particle size, constructed in such a way that a feed pipe leads into a cylindrical distributor chamber and two distributor pipes, each having a shut-off means, lead away from this chamber. In preferred embodiments, the cylindrical distributor chamber has continuous, inwardly-curved weirs around the outlet points to the distributor pipes, and a distributor pipe leads away from each of the two end faces of the cylindrical distributor. This special arrangement results in a low mechanical and/or corrosive stress on the functional components.

The feed pipe leads tangentially into the cylindrical distributor chamber, the distributor pipes lead tangentially away from the distributor chamber, and the distributor chamber includes an internal cylinder to which the tubes are mounted in such a way that they surround the internal cylinder. Owing to this special arrangement, only low mechanical and/or corrosive stresses occur.

Abstract: A duct and flop-gate construction for handling particulate material and a method of handling dust or other particulate material. The collected material drops down a duct which contains a flop-gate for directing the material to either of two bins. A mild current of air is drawn upwardly through the duct and flop-gate counter to the movement of the material to subject the bins to negative pressure and prevent outward leakage. The same duct serves both to carry material downwardly to the bins and as a means for applying negative pressure to the bins.

The metering device includes a blocking mechanism responsive to the control for cyclically blocking and unblocking the conveyance path.

Abstract: A new apparatus for suspending and transporting particulate material is described. The apparatus is particularly useful for transporting and depositing thermal insulation into building spaces. The apparatus includes a conduit junction having a particle inlet conduit for the particulate material, an outlet conduit and an air inlet conduit to supply air under pressure for suspending the particulate material passing into the junction, e.g. from a closed receptacle such as a plastic bag in which the particulate material is stored. The air inlet conduit provides air at superatmospheric pressure to the closed receptacle, thereby placing the stored particulate material and the interior of the receptacle at or above the air pressure in the junction. The particulate material is then able to move into the junction without traversing an air current travelling in the opposite direction. The outlet conduit carries air and particulate material away from the junction to a delivery point.
