Abstract
Abstract A strip recording station having two vacuum rings axially spaced apart to grasp a strip record by its edges and cause the strip to conform to a cylindrical shape surrounding a positionable read/write head. The strip is revolved past the read/write head by rotating the vacuum rings about their axis, as many times as necessary and ejected upon completion of the read/write function.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
66 words
A strip record read/write processing station comprising: a plurality of revolvable vacuum rings coaxially spaced apart; support means internal to said vacuum rings and extending therebetween for rotatably supporting said rings with respect to said support means, said support meAns being stationary with respect to said rings; transducer means positioned between said axially spaced rings; pressure reducing means connected to the interior of said vacuum rings.
Claim 2
Dependent Claim
66 words
A strip record read/write processing station comprising: a plurality of revolvable vacuum rings coaxially spaced apart; support means internal to said vacuum rings and extending therebetween for rotatably supporting said rings with respect to said support means, said support meAns being stationary with respect to said rings; transducer means positioned between said axially spaced rings; pressure reducing means connected to the interior of said vacuum rings.
Claim 3
Dependent Claim
28 words
A strip record read/write processing station as in claim 1 wherein said transducer means is slidably positionable on an axis parallel to the axis of said vacuum rings.
Claim 4
Dependent Claim
36 words
A strip record read/write processing station as in claim 1 wherein said rings have a plurality of orifices extending radially therethrough and spaced uniformly around the peripheries of said rings, communicating with said pressure reducing means.
Claim 5
Dependent Claim
23 words
A strip record read/write processing station as in claim 3 wherein said station further comprises fluid impinging means partially radially surrounding said cylinder.
Claim 6
Dependent Claim
32 words
A strip record read/write processing station as in claim 3 wherein said station further comprises synchronous driving means connected to said rings, driving each of said rings at identical velocities and directions.
Claim 7
Dependent Claim
34 words
A strip record read/write processing station as in claim 3 in combination with selectively operably gating means supported adjacent to said cylinder controlling the entrance and exiting of a strip record from said station.
Claim 8
Dependent Claim
45 words
A strip record read/write processing station as in claim 6 wherein said gating means further includes a selectively operated entrance gate to cause a record strip to enter said station and a selectively operated exit gate to allow said record strip to exit said station.
Claim 9
Dependent Claim
96 words
A record strip processing station for transporting a record strip in a cylindrical path with minimal abrasive damage comprising: a support means; two vacuum rings rotatably mounted on said support means to grasp and transport said record strip by said strips edges, with the recording surface of said strip inwardly directed toward the axis of said cylindrical path; transducer means supported between said rings and adjacent said cylindrical path; fluid impinging means partially radially surrounding said cylindrical path to direct fluid flow against the other surface of said strip maintaining a cylindrical shape of said strip.
Claim 10
Dependent Claim
96 words
A record strip processing station for transporting a record strip in a cylindrical path with minimal abrasive damage comprising: a support means; two vacuum rings rotatably mounted on said support means to grasp and transport said record strip by said strips edges, with the recording surface of said strip inwardly directed toward the axis of said cylindrical path; transducer means supported between said rings and adjacent said cylindrical path; fluid impinging means partially radially surrounding said cylindrical path to direct fluid flow against the other surface of said strip maintaining a cylindrical shape of said strip.
Claim 11
Dependent Claim
154 words
A record strip processing station for transporting in a cylindrical path, reading and recording a record strip with minimal abrasive damage and maximum control of recording quality and variations comprising: a support means; two ported vacuum drive rings rotatably mounted on said support means and spaced apart from each other attracting and forming said strip into a partial cylindrical shape with the recording surface of said strip directed inwardly toward the axis of said cylindrical shape; transducer means moveably supported between said rings to read and record said record strip; actuator means connected to said transducer means and support means to align said transducer means with said strip; vacuum means connected to said vacuum drive rings providing attractive forces of said rings; synchronous drive means connected to said vacuum rings, rotating said rings and transporting said strip; fluid impinging means partially surrounding said cylindrical path to maintain said partial cylindrical shape of said strip.
