Abstract
Abstract A train of information is sectioned into two groupings of information. Each grouping is an alternate sample of the original information and is channeled to one ear of a listener thereby adjusting the listening time with minimal discarding of any of the original information. Two quadripole transducers, secured to a shaft so as to be offset with respect to each other, sample the original information to obtain the two groupings.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
66 words
A method for time adjustment of information comprising: sectioning a train of information into two different groupings of information, each of said two groupings being a series of alternate sections; abutting the sectioned information in each of said two groupings of information so that it is a continuous grouping of alternate sections; and simultaneously channeling each of said two groupings of information to separate listening devices.
Claim 2
Independent Claim
66 words
A method for time adjustment of information comprising: sectioning a train of information into two different groupings of information, each of said two groupings being a series of alternate sections; abutting the sectioned information in each of said two groupings of information so that it is a continuous grouping of alternate sections; and simultaneously channeling each of said two groupings of information to separate listening devices.
Claim 3
Independent Claim
86 words
A method for time adjustment of information comprising: sectioning a train of information into two different groupings of information, each of said two groupings being a series of alternate sections; abutting the sectioned information in each of said two groupings of information so that it is a continuous grouping of alternate sections; and simultaneously channeling each of said two groupings of information to two separate listening devices so that transitions between sections of information in each of said two groupings occur at different points in time.
Claim 4
Independent Claim
86 words
A method for time adjustment of information comprising: sectioning a train of information into two different groupings of information, each of said two groupings being a series of alternate sections; abutting the sectioned information in each of said two groupings of information so that it is a continuous grouping of alternate sections; and simultaneously channeling each of said two groupings of information to two separate listening devices so that transitions between sections of information in each of said two groupings occur at different points in time.
Claim 5
Dependent Claim
87 words
Apparatus for time adjustment of information comprising: an information recording element having two recording tracks with a continuous train of information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of alternate intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; and means for providing relative movement between said recording element and said transducer devices.
Claim 6
Dependent Claim
87 words
Apparatus for time adjustment of information comprising: an information recording element having two recording tracks with a continuous train of information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of alternate intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; and means for providing relative movement between said recording element and said transducer devices.
Claim 7
Dependent Claim
19 words
The apparatus of claim 3 wherein there is provided means for restoring the original frequency to said intermittent portions.
Claim 8
Dependent Claim
17 words
The apparatus of claim 4 wherein there is provided means for listening to said frequency-restored intermittent portions.
Claim 9
Dependent Claim
45 words
The apparatus of claim 5 wherein said means for listening comprises two listening devices, one listening device adapted to pick up frequency-restored intermittent portions of one transducer device, and the other listening device adapted to pick up frequency-restored intermittent portions of the other transducer device.
Claim 10
Dependent Claim
137 words
Apparatus for time adjustment of information comprising: an Information recording element having two recording tracks with information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; means for providing relative movement between said recording element and said transducer devices; means for restoring the original frequency to said intermittent portions; means for listening to said frequency-restored intermittent portions; and means for mounting said two transducer devices so that said plurality of pickup heads associated with one of said transducer devices is offset with respect to said plurality of pickup heads associated with the other transducer device.
Claim 11
Dependent Claim
137 words
Apparatus for time adjustment of information comprising: an Information recording element having two recording tracks with information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; means for providing relative movement between said recording element and said transducer devices; means for restoring the original frequency to said intermittent portions; means for listening to said frequency-restored intermittent portions; and means for mounting said two transducer devices so that said plurality of pickup heads associated with one of said transducer devices is offset with respect to said plurality of pickup heads associated with the other transducer device.
Claim 12
Dependent Claim
45 words
The apparatus of claim 7 wherein said means for listening comprises two listening devices, one listening device adapted to pick up frequency-restored intermittent portions of one transducer device, and the other listening device adapted to pick up frequency-restored intermittent portions of the other transducer device.
Claim 13
Dependent Claim
122 words
Apparatus for time adjustment of information comprising: an information recording element having two recording tracks with information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; means for providing relative movement between said recording element and said transducer devices; and means for mounting said two transducer devices so that said so that said plurality of pickup heads associated with one of said transducer devices is offset with respect to said plurality of pickup heads associated with the other transducer device.
Claim 14
Dependent Claim
122 words
Apparatus for time adjustment of information comprising: an information recording element having two recording tracks with information recorded in phase on each of said tracks; two transducer devices, each having a plurality of pickup heads, each transducer device being positioned for sequential and continuous pickup of intermittent portions of the information recorded on one of said tracks at a frequency different from the original frequency at which recorded; means for providing relative movement between said recording element and said transducer devices; and means for mounting said two transducer devices so that said so that said plurality of pickup heads associated with one of said transducer devices is offset with respect to said plurality of pickup heads associated with the other transducer device.
