Abstract
Abstract The impregnants for electrolytic recording paper are divided into two or more parts thereby separating parts which may react with time, and/or be oxidized by atmosphere or light from those used to cause other reactions when in contact with metallic substances, which may ionize in an electrolyte, resulting in a long life package. Not only may there be electrolysis, but there may also be reactions with the paper or extraneous ingredients in the paper. Paper and electrolyte packaged in this manner will not only keep for long periods but will also withstand very severe environmental conditions without change or deterioration. Such packaging is of a special utility in military applications.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
In an electrolytic recording paper package, the combination of: a two part package; a roll of paper in one of said parts; an electrolyte in the second of said parts; and wherein said roll of paper is impregnated with a solution comprising a predetermined selection from the ingredients making up an electrolytic marking solution exclusive of marking compounds and a solution of the balance of the ingredients of said solution comprising said electrolyte in the second of said parts.
Claim 2
Dependent Claim
79 words
In an electrolytic recording paper package, the combination of: a two part package; a roll of paper in one of said parts; an electrolyte in the second of said parts; and wherein said roll of paper is impregnated with a solution comprising a predetermined selection from the ingredients making up an electrolytic marking solution exclusive of marking compounds and a solution of the balance of the ingredients of said solution comprising said electrolyte in the second of said parts.
Claim 3
Dependent Claim
33 words
An electrolytic recording paper package as set forth in claim 1; and including an intermediate third part between said two parts containing an indicator for indicating leakage of electrolyte from said second part.
Claim 4
Dependent Claim
40 words
An electrolytic recording paper package as set forth in claim 2; and including a first clamp between said intermediate part and said one of said parts and a second clamp between said intermediate part and said second of said parts.
Claim 5
Dependent Claim
43 words
An electrolytic recording paper package as set forth in claim 2; and including a dual clamp for sealing an area of said package between said intermediate part and said one of said parts and said intermediate part and said second of said parts.
Claim 6
Dependent Claim
92 words
In an electrolytic recording paper package, the combination of: a two part package; means for sealing one of said parts from the other; a roll of recording paper impregnated with an electrolytic composition which is substantially free from marking compound contained in one of said parts; and an electrolyte including a marking compound along with a predetermined amount of water for completing the impregnation of said paper and for bringing said paper to a predetermined moisture content in combination with said impregnation of said paper contained in the other of said parts.
Claim 7
Dependent Claim
92 words
In an electrolytic recording paper package, the combination of: a two part package; means for sealing one of said parts from the other; a roll of recording paper impregnated with an electrolytic composition which is substantially free from marking compound contained in one of said parts; and an electrolyte including a marking compound along with a predetermined amount of water for completing the impregnation of said paper and for bringing said paper to a predetermined moisture content in combination with said impregnation of said paper contained in the other of said parts.
Claim 8
Dependent Claim
112 words
In an electrolytic recording paper package the combination of: a two part package; means for sealing one of said parts from the other; a recording paper roll impregnated with a salt chosen from the group comprising sodium nitrate and potassium nitrate, sodium phosphate, and oxalic acid sufficient to provide pH of the order of 3 to 5 and enough water to provide a predetermined moisture content contained in one of said parts; and an electrolyte comprising a marking compound, a stabilizer, a wetting agent and sufficient water to provide a predetermined liquid content to said electrolytic recording paper in combination with said predetermined moisture content contained in the second of said parts.
Claim 9
Dependent Claim
