Abstract
Abstract A system which accepts an input medium and provides an output copy having a right hand edge which is controlled by means of a variable control zone. The control zone may be made 1) relatively wide with a resultant extremely ragged right hand edge; 2) quite narrow with a resultant slightly ragged right hand edge; or 3) equal to a value of one escapement unit with a resultant even right hand edge. The system is operable such that in the event that more than one word space occurs in the zone, the word space nearest to the right hand side of the zone which corresponds to the end of the measure is chosen. No operator intervention is necessary to achieve the desired result after the system has been started.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
294 words
A system for automatically controlling, after set up, the alignment of output lines to be printed without requiring hyphenation decisions from character and space codes input to said system, said system comprising: means for holding an operator selected measure count; means for holding an operator selected control zone count; means for holding a count equal to said measure count minus said control zone count; means for holding an operator selected minimum interword space size count: means for tabulating a running count of said character and space codes from the left hand margin of said output lines up to a point of last space which does not exceed said measure count; means for holding a multiple of said control zone count; means for tabulating a running count of said space codes from the left margin of said output lines up to said measure count; means for comparing said point of last space in said running count of said character and space codes for said output lines, which does not exceed said measure count, with said count equal to said measure count minus said control zone count; and means upon said comparison 1) for causing a carrier return signal when said point of last space exceeds said count equal to said measure count minus said control zone count; and 2) when said point of last space does not exceed said count equal to said measure count minus said control zone count for adding, for justification purposes, a multiple of said control zone count to said minimum interword space size count for said running count of said space codes up to said point of last space for causing said point of last space to exceed said count equal to said measure count minus said control zone count.
Claim 2
Independent Claim
294 words
A system for automatically controlling, after set up, the alignment of output lines to be printed without requiring hyphenation decisions from character and space codes input to said system, said system comprising: means for holding an operator selected measure count; means for holding an operator selected control zone count; means for holding a count equal to said measure count minus said control zone count; means for holding an operator selected minimum interword space size count: means for tabulating a running count of said character and space codes from the left hand margin of said output lines up to a point of last space which does not exceed said measure count; means for holding a multiple of said control zone count; means for tabulating a running count of said space codes from the left margin of said output lines up to said measure count; means for comparing said point of last space in said running count of said character and space codes for said output lines, which does not exceed said measure count, with said count equal to said measure count minus said control zone count; and means upon said comparison 1) for causing a carrier return signal when said point of last space exceeds said count equal to said measure count minus said control zone count; and 2) when said point of last space does not exceed said count equal to said measure count minus said control zone count for adding, for justification purposes, a multiple of said control zone count to said minimum interword space size count for said running count of said space codes up to said point of last space for causing said point of last space to exceed said count equal to said measure count minus said control zone count.
Claim 3
Dependent Claim
40 words
A system according to claim 1 further including means for comparing a count of said character and space codes with said measure count upon each space code input to said system for determining when said measure count has been exceeded.
Claim 4
Dependent Claim
46 words
A system according to claim 2 further including means for gating a count for each space code input to said system to said means for tabulating a running count of said space codes when said character and space code count does not exceed said measure count.
Claim 5
Dependent Claim
62 words
A system according to claim 3 further including means for gating said count of said character and space codes up to said point of last space to said means for comparing said point of last space with said measure count minus said control zone count when said count of said character and space codes from said left margin exceed said measure count.
