Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
A device for external attachment to a computer diskette drive having a slotted aperture, comprising: a base having a first and second surfaces including a first aperture and a second aperture extending therethrough, said first aperture featuring a recessed flange and dimensioned to receive a screw and said second aperture being surrounded by a recess on said first surface dimensioned to receive a stop washer of a desired configuration, and a recessed flange formed in said second surface dimensioned to receive a nut, a rotatable blocking means for blocking the diskette drive when rotated from an unblocking position to a blocking position, said blocking means having a cylindrical core with axially extending grooves, a lock plug featuring retractable pins, and a shaft of non-circular cross-sectional dimensions, said lock plug being positionable in the core of said blocking means and said shaft extending through said blocking means, a stop washer of desired configuration to correspond to said recess, and having an aperture of corresponding dimensions to the cross-section of said shaft, a nut dimensioned to attach to said shaft where said shaft extends through said stop washer and is attached to said base with said nut, a screw for passing through said first aperture and dimensioned to pass into the computer, and a plug dimensioned to fit into said first aperture over said screw.
Claim 2
Independent Claim
223 words
A device for external attachment to a computer diskette drive having a slotted aperture, comprising: a base having a first and second surfaces including a first aperture and a second aperture extending therethrough, said first aperture featuring a recessed flange and dimensioned to receive a screw and said second aperture being surrounded by a recess on said first surface dimensioned to receive a stop washer of a desired configuration, and a recessed flange formed in said second surface dimensioned to receive a nut, a rotatable blocking means for blocking the diskette drive when rotated from an unblocking position to a blocking position, said blocking means having a cylindrical core with axially extending grooves, a lock plug featuring retractable pins, and a shaft of non-circular cross-sectional dimensions, said lock plug being positionable in the core of said blocking means and said shaft extending through said blocking means, a stop washer of desired configuration to correspond to said recess, and having an aperture of corresponding dimensions to the cross-section of said shaft, a nut dimensioned to attach to said shaft where said shaft extends through said stop washer and is attached to said base with said nut, a screw for passing through said first aperture and dimensioned to pass into the computer, and a plug dimensioned to fit into said first aperture over said screw.
Claim 3
Independent Claim
166 words
A method for retrofitting a blocking device for computer data drive access aperture, comprising the steps of: selecting a solvent capable of dissolving the thermoplastic composition of the computer data drive, forming a housing containing a key-actuated lock plug where the housing and lock plug are rotatable relative to one another, forming a base to which the housing and lock plug are connected from a thermoplastic composition capable of partial dissolution in the selected solvent, affixing a blocker lug in a rotatable relationship relative to the base, positioning the base proximate to the access aperture on the computer data drive, applying the selected solvent to the surface of the base abutting the computer data drive and to the computer data drive, and screwing the base onto the computer data drive where the base is partially amalgamated with the computer data drive via the solvent and is mechanically affixed to the data drive by the screw, and rotating the blocker lug to block the data drive aperture.
Claim 4
Independent Claim

Claim 5
Independent Claim
173 words
A device for external attachment to a computer diskette drive having a slotted aperture, comprising: a base having a first and second surfaces including a first aperture being surrounded by a recess on said first surface dimensioned to receive a stop washer of a desired configuration, and a recessed flange formed in said second surface dimensioned to receive a nut, a rotatable blocking means for blocking the diskette drive when rotated from an unblocking position to a blocking position, said blocking means having a cylindrical core with axially extending grooves, a lock plug featuring retractable pins, and a shaft of non-circular cross-sectional dimensions, said lock plug being positionable in the core of said blocking means and said shaft extending through said blocking means, a stop washer of desired configuration to correspond to said recess, and having an aperture of corresponding dimensions to the cross-section of said shaft, and a nut dimensioned to attach to said shaft where said shaft extends through said stop washer and is attached to said base with said nut.
Claim 6
Independent Claim
173 words
A device for external attachment to a computer diskette drive having a slotted aperture, comprising: a base having a first and second surfaces including a first aperture being surrounded by a recess on said first surface dimensioned to receive a stop washer of a desired configuration, and a recessed flange formed in said second surface dimensioned to receive a nut, a rotatable blocking means for blocking the diskette drive when rotated from an unblocking position to a blocking position, said blocking means having a cylindrical core with axially extending grooves, a lock plug featuring retractable pins, and a shaft of non-circular cross-sectional dimensions, said lock plug being positionable in the core of said blocking means and said shaft extending through said blocking means, a stop washer of desired configuration to correspond to said recess, and having an aperture of corresponding dimensions to the cross-section of said shaft, and a nut dimensioned to attach to said shaft where said shaft extends through said stop washer and is attached to said base with said nut.
Claim 7
Dependent Claim
36 words
A device according to claim 3 where the base is comprised of a polymer selected from the group consisting of polycarbonate blends, polyphenylene oxide, and high impact polystyrene to permit solvent bonding to a computer drive.
Claim 8
Dependent Claim
31 words
A device according to claim 3 where the base includes a second aperture and further comprising attachment means for attaching said aperture to the computer by extending through said second aperture.
Claim 9
Dependent Claim
13 words

Claim 10
Independent Claim
136 words
A method for retrofitting a blocking device for computer data drive access aperture, the blocking device including a housing containing a key-actuated lock plug where the housing and lock plug are rotatable relative to one another, a base to which the housing and lock plug are connected, and a blocker lug rotatable relative to the base, comprising the steps of: positioning the base proximate to the access aperture on the computer data drive, choosing a material selected from the group consisting of an epoxy adhesive and a solvent capable of dissolving the thermoplastic composition of the computer data drive, applying the selected material to the surface of the base abutting the computer data drive, to mechanically affix the blocking device to the commuter data drive, and rotating the blocker lug to block the data drive aperture.
