Abstract
Abstract A container with at least one nozzle for introducing turbulent compressed air into the container for transport of granular or sluggishly flowing material out of the container, which nozzle forms the outlet from a housing into which the air is pulsed by means of a rotor driven by the air entering the housing, which rotor may be eccentric balanced to produce vibrations of the housing in the container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
Improvement in a container for compressed air transport of granular material or sluggishly flowing material comprising at least one nozzle (3) arranged on the inner peripheral surface of the container (1) for introduction of compressed air, with plateshaped element (6) provided with turbulence-producing channels connected in front of the nozzle (3), characterized in that the plate-shaped element (6) is mounted in a cylindrical housing (4) connected to the nozzle (3), that in the housing (4), between the element (6) and the end wall (8) of the housing, a rotor (9) is provided for production of vibrations, and that the compressed air is introduced into the housing through an inlet pipe (5) arranged eccentricly to the housing (4) on the peripheral surface of the housing in the area of the rotor (9).
Claim 2
Dependent Claim
131 words
Improvement in a container for compressed air transport of granular material or sluggishly flowing material comprising at least one nozzle (3) arranged on the inner peripheral surface of the container (1) for introduction of compressed air, with plateshaped element (6) provided with turbulence-producing channels connected in front of the nozzle (3), characterized in that the plate-shaped element (6) is mounted in a cylindrical housing (4) connected to the nozzle (3), that in the housing (4), between the element (6) and the end wall (8) of the housing, a rotor (9) is provided for production of vibrations, and that the compressed air is introduced into the housing through an inlet pipe (5) arranged eccentricly to the housing (4) on the peripheral surface of the housing in the area of the rotor (9).
Claim 3
Dependent Claim
34 words
Improvement according to claim 1, characterized in that the rotor is formed as one or more rod-shaped elements (9) having a closure plate (10) for the inlet pipe (5) at least at one end.
Claim 4
Dependent Claim
25 words
Improvement according to claim 2, characterized in that the closure plate (10) is obliquely disposed with respect to the cylindrical surface of the housing (4).
Claim 5
Dependent Claim
29 words
Means according to claim 2, characterized in that the rotor (9) is produced from light materials and has its centre of gravity located at the axis of rotation (7).
Claim 6
Dependent Claim
30 words
Means according to claim 2, characterized in that the rotor (9) is produced from heavy materials and has its centre of gravity located eccentrically to the axis of rotation (7).
