Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
135 words
Jacket container means adapted to house a prescribed pack of flexible disk records and to accommodate the rotation and partition of the pack, within the jacket as well as accommodating the selectible introduction of transducer means to operate upon this pack, and also adapted to accommodate registration within associated automatic disk drive apparatus automatically so-rotating, partitioning and transducing this pack, this said container means comprising: a pair of like panel means joined along two opposing edges by a pair of like side-wall means and further joined along an intermediate bottom-edge by bottom-wall means; said wall means all being dimensioned and adapted to accommodate the full partitioned height of said pack when so operated in situ and also being configured and adapted to be automatically non-rotatably positioned in said apparatus for automatically carrying out said operations.
Claim 2
Dependent Claim
135 words
Jacket container means adapted to house a prescribed pack of flexible disk records and to accommodate the rotation and partition of the pack, within the jacket as well as accommodating the selectible introduction of transducer means to operate upon this pack, and also adapted to accommodate registration within associated automatic disk drive apparatus automatically so-rotating, partitioning and transducing this pack, this said container means comprising: a pair of like panel means joined along two opposing edges by a pair of like side-wall means and further joined along an intermediate bottom-edge by bottom-wall means; said wall means all being dimensioned and adapted to accommodate the full partitioned height of said pack when so operated in situ and also being configured and adapted to be automatically non-rotatably positioned in said apparatus for automatically carrying out said operations.
Claim 3
Dependent Claim
52 words
The combination as recited in claim 1, wherein said container means also includes sealing means along a mouth edge opposite said bottom-edge and is adapted to accommodate associated spreading means for automatically opening and unsealing said sealing means so as to admit said transducing means for operation upon the pack contained within.
Claim 4
Dependent Claim
60 words
The combination as recited in claim 2, wherein said container means is also adapted to be expanded with said panels being spread apart to better accommodate said rotation, partition and transducing operations, in situ and wherein said container means is also adapted to accommodate expander means adapted to automatically thrust said panel means apart for so expanding the container means.
Claim 5
Dependent Claim
22 words
The combination as recited in claim 3 wherein said wall means are made expandable along their width to accommodate said spreading means.
Claim 6
Dependent Claim
28 words
The combination as recited in claim 3 wherein said wall means are made wide enough to accommodate said rotation, partition and transducer operations of said pack in situ.
Claim 7
Dependent Claim
50 words
The combination as recited in claim 1 wherein said container means is also made normally self-sealing against the intrusion of dust and the like into the region of the pack contained within and wherein the container means is further adapted to be automatically unsealed for injection of said transducer means.
Claim 8
Dependent Claim
41 words
The combination as recited in claim 6 wherein said container means is also adapted to accommodate spreader means automatically operative to unseal said container means and admit said transducer means when the container means is inserted into said disk drive apparatus.
Claim 9
Dependent Claim
54 words
The combination as recited in claim 7 wherein said container means comprises at least one flap means along the top edge of said container means opposite said bottom-edge; said flap means being spring-urged to normaly be disposed in closed sealing condition while also adapted to accommodate spreader means to divert the flap means unsealingly.
Claim 10
Dependent Claim
22 words
The combination as recited in claim 8 wherein said container means includes holes in said panel means to accommodate such spreader means.
Claim 11
Dependent Claim
43 words
The combination as recited in claim 9 wherein said spreader means comprise a plurality of plungers adapted to be injected through said holes so as to thrust said panel means apart sufficiently to accommodate said rotation, partition and transducing operations on said pack.
Claim 12
Dependent Claim
94 words
An improved cartridge comprising a jacket container means together with partitionable pack of flexible disk records contained there within said jacket container means comprising: a pair of like panel means joined along two opposing edges by a pair of like side-wall means and further joined along an intermediate bottom-edge by bottom-wall means; said wall means all being dimensioned and adapted to accommodate the full partitioned height of said pack when so operated in situ and also being configured and adapted to be automatically non-rotatably positioned in said apparatus for automatically carrying out said operations.
Claim 13
Dependent Claim
94 words
An improved cartridge comprising a jacket container means together with partitionable pack of flexible disk records contained there within said jacket container means comprising: a pair of like panel means joined along two opposing edges by a pair of like side-wall means and further joined along an intermediate bottom-edge by bottom-wall means; said wall means all being dimensioned and adapted to accommodate the full partitioned height of said pack when so operated in situ and also being configured and adapted to be automatically non-rotatably positioned in said apparatus for automatically carrying out said operations.
Claim 14
Dependent Claim

Claim 15
Dependent Claim
100 words
Improved disk drive apparatus adapted to receive a cartridge containing a pack of floppy disk records adapted to be rotated, partitioned and transduced while held within jacket container means, said apparatus being adapted to automatically receive such cartridge and thereafter selectably and automatically invoke said rotation, partition and transducing operations while holding said jacket means in a prescribed position non-rotatably; said apparatus also including automatic jacket spreader means adapted to automatically open said jacket to accommodate said pack rotation, partition and other manipulation while also including automatic pack partition means adapted to partition said disk pack for said transducing operations.
Claim 16
Dependent Claim
100 words
Improved disk drive apparatus adapted to receive a cartridge containing a pack of floppy disk records adapted to be rotated, partitioned and transduced while held within jacket container means, said apparatus being adapted to automatically receive such cartridge and thereafter selectably and automatically invoke said rotation, partition and transducing operations while holding said jacket means in a prescribed position non-rotatably; said apparatus also including automatic jacket spreader means adapted to automatically open said jacket to accommodate said pack rotation, partition and other manipulation while also including automatic pack partition means adapted to partition said disk pack for said transducing operations.
Claim 17
Dependent Claim
