Abstract: A seeding machine (1) and method of use, for introducing seed material into a soil (11), with a first ploughing device for drawing at least one furrow into the soil and a filling device for closing the first furrow. A dust separator (5) separates air during the seeding process into an air component (13) and a dust component (7). A line from the dust separator delivers the dust component separated from the air component into the soil.

Abstract: The invention relates to a seeding machine (1) for introducing seed material into a soil (11), comprising a first ploughing device for drawing at least one furrow into the soil and a filling means for closing the first furrow, furthermore comprising a dust separator (5) through which air that is aspired during the seeding process and contains dust particles can be separated into an air component (13) and a dust component (7), characterised in that introducing means (10) for introducing the dust component separated from the air component into the soil are provided. The invention also relates to a seeding method.

Abstract: Apparatus for separation of particles from a fluid stream entraining said particles comprises an inlet zone, a centrifugal separation zone, particles collection means and exhaust means, in which the inlet and separation zones are in communication via a transition zone for inducing vortical flow in the fluid stream, the transition zone having a diameter greater than the diameter of the inlet zone and comprising means defining an outlet port to the separation zone, an entry port being formed in the transition zone upstream of the baffle means, the entry and outlet ports being mutually arranged to minimise fluid perturbation in the fluid stream in use.

Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical separation container, an inlet tube parallel to the axis of the chamber having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the separation chamber tube. The separation chamber includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the separation chamber includes a curved surface and sharp edge for lifting air flow off the chamber wall. A outlet tube disc spaced from the inlet of the outlet tube is located in the chamber below the disrupter ring.

Abstract: A dirt separation and collection assembly suitable for use in a bagless vacuum cleaner including two dirt separation and collection zones is provided. Dirty air enters the upper portion of a container and enters a first stage dirt separation zone including a disruptor ring extending inwardly from the outer wall to allow coarse dirt particles and fibers to pass through and collect at the base of the outer wall of the device. The spinning air is then drawn through a conical shroud and fed into a second stage conical separator for separating fine dirt particles and collecting them in an inner substantially cylindrical collection chamber. Air exits the conical separator at the opposite cone opening before being drawn to the suction source. Elements may be oriented upwardly or downwardly depending upon the configuration of the housing for receiving the dirt separation and collection assembly.

Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical housing, an inlet tube parallel to the axis of the housing having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the housing. The housing includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the housing includes a curved surface and sharp edge for lifting air flow off the housing wall. An outlet tube disc spaced from the inlet of the outlet tube is located in the housing below the disrupter ring.

Abstract: A dirt separation and collection container suitable for use in a bagless vacuum cleaner including two dirt separation and collection zones is provided. Dirty air enters the mid-section of the device and enters a first stage dirt separation zone including a cylindrical baffle spaced inwardly from the outer wall of the device with an inclined slot to allow coarse dirt particles and fibers to pass through and collect at the base of the outer wall of the device. The spinning air is then fed into a second stage conical separator for separating fine dirt particles and collecting them in an inner substantially cylindrical collection chamber. Air exits the conical separator and device opposite the cone opening before being drawn to the suction source. Elements may be oriented upwardly or downwardly depending upon the configuration of the housing for receiving the dirt separation and collection device.
