Abstract
Abstract Methodology and apparatus for representing many numbers in an ordered sequence of numbers by substitute numbers where each such substitute number consists of fewer digits than the number for which it has been substituted and storing and processing signals representative of all the numbers in the ordered sequence, including the substitute numbers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A method of recording signals representative of a collection of numbers, each number being comprised of a plurality of digits, which numbers were at first randomly required and subsequently arranged in an ordered sequence of relative magnitude wherein N successive such numbers after a first such number differ from said first number by no more than a predetermined number of lesser significant digits without having to record signals representative of all the digits of every number in the collection comprising: recording on a storage medium having a finite storage space signals representative of all the digits of the first number of the ordered sequence; and, recording in succession signals representative of only no more than a predetermined number of the lesser significant digits of the N successive numbers of the ordered sequence of numbers, whereby signals representative of the entire collection of numbers is recorded on the storage medium within said finite storage space.
Claim 2
Independent Claim
154 words
A method of recording signals representative of a collection of numbers, each number being comprised of a plurality of digits, which numbers were at first randomly required and subsequently arranged in an ordered sequence of relative magnitude wherein N successive such numbers after a first such number differ from said first number by no more than a predetermined number of lesser significant digits without having to record signals representative of all the digits of every number in the collection comprising: recording on a storage medium having a finite storage space signals representative of all the digits of the first number of the ordered sequence; and, recording in succession signals representative of only no more than a predetermined number of the lesser significant digits of the N successive numbers of the ordered sequence of numbers, whereby signals representative of the entire collection of numbers is recorded on the storage medium within said finite storage space.
Claim 3
Independent Claim
115 words
A method of recording a collection of randomly acquired numbers on a storage medium having a plurality of recording channels, each number being comprised of a plurality of digits and wherein none of the numbers in the collection differs from the lowest number in the collection in more than a predetermined number of lesser significant digit locations comprising: recording signal representative of all of the digits of the lowest number in the collection in a first channel of the storage medium; and, recording in succeeding channels in said storage medium signals representative of no more than the differing digits in the predetermined number of lesser significant digit locations of successively higher numbers in said collection.
Claim 4
Independent Claim
115 words
A method of recording a collection of randomly acquired numbers on a storage medium having a plurality of recording channels, each number being comprised of a plurality of digits and wherein none of the numbers in the collection differs from the lowest number in the collection in more than a predetermined number of lesser significant digit locations comprising: recording signal representative of all of the digits of the lowest number in the collection in a first channel of the storage medium; and, recording in succeeding channels in said storage medium signals representative of no more than the differing digits in the predetermined number of lesser significant digit locations of successively higher numbers in said collection.
Claim 5
Independent Claim
112 words
A method of recording a collection of randomly acquired numbers on a storage medium having a plurality of recording channels, each number being comprised of a plurality of digits and wherein none of the numbers in the collection differs from the highest number in the collection in more than a predetermined number of lesser significant digit locations comprising: recording signals representative of all of the digits of the highest number in a first channel of the storage medium; and, recording in successive channels in said storage medium signals representative of no more than the differing digits in the predetermined number of lesser significant digit locations of successively lower numbers in said collection.
Claim 6
Independent Claim
112 words
A method of recording a collection of randomly acquired numbers on a storage medium having a plurality of recording channels, each number being comprised of a plurality of digits and wherein none of the numbers in the collection differs from the highest number in the collection in more than a predetermined number of lesser significant digit locations comprising: recording signals representative of all of the digits of the highest number in a first channel of the storage medium; and, recording in successive channels in said storage medium signals representative of no more than the differing digits in the predetermined number of lesser significant digit locations of successively lower numbers in said collection.
