Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
223 words
A system for processing intelligence recorded by deposits of magnetizable ink in form of binary bar patterns, said system including a. a rotatable platen roller (9); b. auxiliary rollers (10) for maintaining sheets (8) of paper in engagement with said platen roller (9) to cause joint movements of sheets (8) of paper with said platen roller (9); c. magnetic modulating means (MH) and magnetic readout means (RH) in cooperative relation to a portion of the surface of said platen roller (9) situated between said auxiliary rollers (10); d. an electric motor (14) for moving said modulating means (MH) and said readout means (RH) relative to said platen roller (10); e. a transmission (12, 12'', 12'''') interposed between said electric motor (14) and said modulating means (MH) and said readout means (RH) to convert rotary motions of said electric motor (14) into oscillary motions of said modulating means (MH) and said readout means (RH) parallel to the axis of said platen roller (9); and f. control means for modulating means (MH) and said readout means (RH) to render said modulating means (MH) effective and said readout means (RH) ineffective during the time of the motions thereof in one direction, and to render said modulating means (MH) ineffective and said readout means (RH) effective during the time of the motions thereof in the opposite direction.
Claim 2
Independent Claim
223 words
A system for processing intelligence recorded by deposits of magnetizable ink in form of binary bar patterns, said system including a. a rotatable platen roller (9); b. auxiliary rollers (10) for maintaining sheets (8) of paper in engagement with said platen roller (9) to cause joint movements of sheets (8) of paper with said platen roller (9); c. magnetic modulating means (MH) and magnetic readout means (RH) in cooperative relation to a portion of the surface of said platen roller (9) situated between said auxiliary rollers (10); d. an electric motor (14) for moving said modulating means (MH) and said readout means (RH) relative to said platen roller (10); e. a transmission (12, 12'', 12'''') interposed between said electric motor (14) and said modulating means (MH) and said readout means (RH) to convert rotary motions of said electric motor (14) into oscillary motions of said modulating means (MH) and said readout means (RH) parallel to the axis of said platen roller (9); and f. control means for modulating means (MH) and said readout means (RH) to render said modulating means (MH) effective and said readout means (RH) ineffective during the time of the motions thereof in one direction, and to render said modulating means (MH) ineffective and said readout means (RH) effective during the time of the motions thereof in the opposite direction.
Claim 3
Dependent Claim
47 words
A system as specified in claim 1 including a screw drive for operating said modulating means (MH) and said readout meaNs (RH) having a dual helix drive screw (12, 12'', 12'''') arranged parallel to said platen roller (9) inside a gap bounded by said auxiliary rollers (10).
