Abstract:
An anti-reentrainment device is provided for use with a cyclone separator. The anti-reentrainment device has a plurality of vane upwardly extending members positioned in the bottom of a cyclone chamber and extending radially inwardly across the bottom. The vanes separate the bottom of the cyclone from the cyclonic fluid flow portion, thereby creating a reduced flow region above deposited particles settling on the bottom of the cyclone. The device impedes the cyclonic flow from reentraining the deposited particles.

Abstract:
A cyclone separator having an improved efficiency to remove a broader spectrum of contained particles is disclosed. The transverse section of the inner wall of the cyclone separator is configured to impart changes in the rate of acceleration of a fluid as it rotates within the cyclone cavity.
Abstract:
A vacuum cleaner handle is provided which offers improved ergonomic characteristics by providing a grip portion which is rotatably mounted and may be offset from the center line axis of the cleaner head.
Abstract:
A machine for de-aggregating a bale of insulation and blowing de-aggregated insulation, has a single upper de-aggregation member and a single lower de-aggregation member, each de-aggregation member having a rotary mounted shaft having a length and a plurality of paddles angularly staggered around the shaft and extending along the length of the shaft, the paddles of the upper de-aggregation member have first and second paddles having differing lengths and both the first and second paddles are interleaved with the paddles of the lower de-aggregation member.
Abstract:
