Abstract
Abstract Apparatus for separating a suspension into at least two fractions of different densities, which comprises one or more cyclones, each mounted for rotation about an axis spaced therefrom and oriented transversely of said axis, and each having an inlet adapted to communicate with a source of said suspension, a first outlet for discharging the lighter of said two fractions and a second outlet for discharging the heavier of said two fractions and which is more distant from said axis than the first outlet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
Apparatus for separating a suspension into at least two fractions of different densities, which comprises at least one cyclone having a first opening, for the introduction of the suspension, a second opening, for the discharge of the heavier of the separated fractions, and a third opening, for the discharge of the lighter of said fractions, and means for feeding said suspension to said cyclone from a source, said means including at least a rotary housing for receiving said suspension and said cyclone being rigid with said housing, in spaced relationship with respect to the rotational axis of the housing, and communicating with the housing through said first opening.
Claim 2
Dependent Claim
108 words
Apparatus for separating a suspension into at least two fractions of different densities, which comprises at least one cyclone having a first opening, for the introduction of the suspension, a second opening, for the discharge of the heavier of the separated fractions, and a third opening, for the discharge of the lighter of said fractions, and means for feeding said suspension to said cyclone from a source, said means including at least a rotary housing for receiving said suspension and said cyclone being rigid with said housing, in spaced relationship with respect to the rotational axis of the housing, and communicating with the housing through said first opening.
Claim 3
Dependent Claim
66 words
Apparatus according to claim 1, wherein said cyclone has a longitudinal axis transverse to the rotational axis of said housing and said cyclone is so oriented that its second opening may discharge said heavier fraction in a substantially radially outward direction, and which further comprises a conduit connected to said third opening and directing the discharge of said lighter fraction in a substantially radially outward direction.
Claim 4
Dependent Claim
30 words
Apparatus according to claim 2, wherein the outlet end of the conduit and the second opening of said cyclone are substantially equally spaced from the rotational axis of the housing.
Claim 5
Dependent Claim
79 words
Apparatus according to claim 2, wherein said cyclone and said conduit are so oriented that said heavier and lighter fractions may be discharged in different planes transverse to the rotational axis of the housing, and which further comprises a recovery trough having a first channel so disposed as to receive the heavier fraction discharge and a second channel so disposed as to receive the lighter fraction discharge throughout rotation of said cyclone about the rotational axis of the housing.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 2, wherein said cyclone and said conduit each have a nozzle oriented in a direction opposite to the rotational direction of the housing.
Claim 7
Dependent Claim
38 words
Apparatus according to claim 1, wherein the housing is adapted to be connected to said source through a hollow rotary shaft which is solid with said housing and which is subjected to the action of a drive mechanism.
Claim 8
Dependent Claim
31 words
Apparatus according to claim 6, wherein the housing includes an annular chamber coaxial with said hollow shaft and rigidly attached thereto, and a connecting means between said housing and said shaft.
Claim 9
Dependent Claim
34 words
Apparatus according to claim 1, further comprising a second cyclone arranged in cascade relationship with respect to the preceding cyclone and having its first opening connected to the second opening of said preceding cyclone.
