Abstract
Abstract A separator for spacing records in a stack comprises a thin metal plate provided with a central hole whose diameter is larger than the diameter of the central hole of the records and having a self-acting adhesive on one of its faces. The plate is adhesively attachable by means of the self-acting adhesive to one of the faces of a record, in the central zone thereof. An additional part of the separator is constituted by a central portion having a hole whose diameter is at least as great as the diameter of the central hole of the plate, a magnetic zone surrounding the hole, and peripheral portions defining elastic zones that extend over the surface of the additional part. In use, the additional part is magnetically adhered to the metal plate with its elastic zones facing away from the record.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
Separators for spacing records making up a stack of records, comprising a plurality of thin metal plates each provided with a central hole whose diameter is larger than the diameter of the central hole of the records and having a self-acting adhesive on one of its faces, said plates being adhesively attachable to at least one of the faces of each record in the central zone of the latter; and a plurality of parts constituted by a central portion having a hole whose diameter is at least as great as the diameter of the central hole of the plate, a magnetic zone surrounding said hole, and peripheral portions defining elastic zones that extend over the surface of said parts.
Claim 2
Dependent Claim
119 words
Separators for spacing records making up a stack of records, comprising a plurality of thin metal plates each provided with a central hole whose diameter is larger than the diameter of the central hole of the records and having a self-acting adhesive on one of its faces, said plates being adhesively attachable to at least one of the faces of each record in the central zone of the latter; and a plurality of parts constituted by a central portion having a hole whose diameter is at least as great as the diameter of the central hole of the plate, a magnetic zone surrounding said hole, and peripheral portions defining elastic zones that extend over the surface of said parts.
Claim 3
Dependent Claim
34 words
Separators as claimed in claim 1, characterized in that the magnetic zone is constituted by a groove made in the part around the hole, in which groove is inserted a band of magnetic material.
Claim 4
Dependent Claim
15 words
Separators as claimed in claim 2, characterized in that the groove is circular and continuous.
Claim 5
Dependent Claim
24 words
Separators as claimed in claim 2, characterized in that the groove is discontinuous with straight runs arranged according to the sides of a square.
Claim 6
Dependent Claim
36 words
Separators as claimed in claim 1, characterized in that the peripheric portions of the parts are formed like radial extensions each of whose faces is at least partically covered with a band of softly-textured elastic material.
Claim 7
Dependent Claim
113 words
A separator for spacing records in a stack, comprising a thin metal plate provided with a central hole whose diameter is larger than the diameter of the central holes of the records and having a self-acting adhesive on one of its faces, said plate being adhesively attachable at its said one face to one of the faces of a record in the central zone thereof; and a part constituted by a central portion having a hole whose diameter is at least as great as the diameter of the central hole of the plate, a magnetic zone surrounding said hole, and peripheral portions defining elastic zones that extend over a surface of said part.
Claim 8
Dependent Claim
113 words
A separator for spacing records in a stack, comprising a thin metal plate provided with a central hole whose diameter is larger than the diameter of the central holes of the records and having a self-acting adhesive on one of its faces, said plate being adhesively attachable at its said one face to one of the faces of a record in the central zone thereof; and a part constituted by a central portion having a hole whose diameter is at least as great as the diameter of the central hole of the plate, a magnetic zone surrounding said hole, and peripheral portions defining elastic zones that extend over a surface of said part.
Claim 9
Dependent Claim
83 words
A separator as claimed in claim 6, in combination with a record, said plate being adhesively attached at its said one face to one of the faces of the record in the central zone thereof, and said part being magnetically adhered to said metal plate with the hole in its central portion positioned to allow a spindle to pass freely through the central hole of the record and with the elastic zones defined by said peripheral portions being directed away from the record.
