Abstract
Abstract A separator for separating fluid media from minute particles of impuritiesncorporating a housing with a partition arranged to form two chambers, one containing a ferromagnetic filtering packing and the other, a filtering packing in a ferroelectric material; a space at an end of the housing serving to connect the chambers to each other and pipes at the other end of the housing used to feed and discharge a fluid medium; and a magnetic system for a magnetic field in the zone of the housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A separator for separating a fluid medium from minute particles of impurities, comprising: a housing, a partition in said housing, a first chamber and a second chamber defined in said housing by said partition, a means defining space at an end of said housing which connects said chambers to each other, a pipe means connected at a second end of said housing for feeding the fluid medium into said first chamber, a second pipe means connected at the second end of said housing for discharging cleaned fluid medium from said second chamber, a ferroelectric filtering packing contained in said first chamber, a ferromagnetic filtering packing contained in said second chamber, and a magnetic system for producing a magnetic field in the zone of said housing through both said first and second chamber.
Claim 2
Dependent Claim
132 words
A separator for separating a fluid medium from minute particles of impurities, comprising: a housing, a partition in said housing, a first chamber and a second chamber defined in said housing by said partition, a means defining space at an end of said housing which connects said chambers to each other, a pipe means connected at a second end of said housing for feeding the fluid medium into said first chamber, a second pipe means connected at the second end of said housing for discharging cleaned fluid medium from said second chamber, a ferroelectric filtering packing contained in said first chamber, a ferromagnetic filtering packing contained in said second chamber, and a magnetic system for producing a magnetic field in the zone of said housing through both said first and second chamber.
Claim 3
Dependent Claim
16 words
A separator as claimed in claim 1, wherein said ferroelectric packing is made from an electret.
Claim 4
Dependent Claim
19 words
A separator as claimed in claim 1, wherein said chamber with said ferroelectric packing also contains a ferromagnetic packing.
Claim 5
Dependent Claim
28 words
A separator as claimed in claim 1, wherein said ferroelectric packing in said first chamber is spontaneously polarized in the absence of an electric field being applied thereto.
Claim 6
Dependent Claim
25 words
A separator as claimed in claim 1, wherein said first and second chambers are concentrically disposed, with said first chamber disposed inside said second chamber.
Claim 7
Dependent Claim
38 words
A separator as claimed in claim 1, comprising a plurality of said first and second chambers in tubular form, with a respective tubular first chamber contacting a respective tubular second chamber along contiguous walls thereof forming said partition.
Claim 8
Dependent Claim
28 words
A separator as claimed in claim 6, wherein said chamber containing said ferroelectric packing is provided with at least a pair of radially-extending electrodes through said ferroelectric packing.
