Definitions

  • Barber 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.
  • the moisture content of the paper for storage may be reduced to a low value to further promote stability but should not be reduced so far as to render the paper brittle or easily damaged.
  • Another way of greatly increasing the useful life of electrolytic recording paper is to impregnate the paper completely, drive off substantially all the moisture for storage purposes and prior to marking, to restore the optimum water content by merely putting back the proper amount of water.
  • FIG. 1 is a view in perspective of one form of dual package for electrolytic recording paper and electrolyte in accordance with one form of the present invention.
  • FIG. 2 is a view in perspective of a form of core for the paper roll useful in connection with the present invention.
  • FIG. 3 is a view in perspective of a second form of the present invention.
  • FIG. 4 is a view of a second form of closure which may be employed as sealing means between the'two parts of the package which provides a third enclosure useful for enclosing anindicator which shows whether or not there has been leakage between the main packages.
  • FIG. 5 is a plan view of a paper roll suitable for use in accordance with the. present invention wherein the paper roll is coreless.
  • FIG. 1 shows a roll of electrolytic recording paper or the like 1 wound on a suitablecore 2 (although coreless paper rolls may also be used as shown in FIG. 5) and enclosed in a first portion 3 of a two-part sealed package.
  • the second part of the package 6 contains an electrolytic solution 7, an end seal 9 and a clamp 4-5 effectively separating the two portions or parts of the package and preventing electrolyte 7 from reaching paper 1 until clamp 4-5 is removed.
  • the electrolyte 7 in the second part of the package contains the marking compounds such as pyrocatechin, a stabilizer such as thiourea, and an optional wetting agent to promote diffusion of the electrolyte when it comes in contact with the paper and sufficient water to produce optimum moisture content of the impregnated paper when the marking compound plus stabilizer (such as thiourea is released into the paper-containing part of the package and when the electrolyte has been absorbed by the paper.
  • the marking compound plus stabilizer such as thiourea is released into the paper-containing part of the package and when the electrolyte has been absorbed by the paper.
  • the exact amount will depend on the characteristics of the paper and the desired final moisture content.
  • electrolytic paper can be stored for prolonged periods without discoloration and, in particular, that environmental conditions such as elevated temperatures can also be tolerated without color change of the stored paper or deterioration or chemical reaction of the ingredients of the electrolyte and paper impurity reactions.
  • the clamp 4-5 may be removed and electrolyte 7 allowed to penetrate the paper roll 1. As soon as this penetration is complete, the package may be opened and the paper placed in the facsimile recorder or similar marking device ready for use.
  • FIG. 3 Another method of greatly prolonging the useful life of electrolytic-recording paper is to impregnate the paper with all of the various marking compounds and then to remove the water content as by vacuum drying whereupon the paper is sealed and may be stored for long periods.
  • the second part of FIG. 3 is a modified form of two-part package in which a large outer package 10 sealed along one end at 11 contains the paper roll 1-2 treated as described above and a second package 13 containing the electrolyte 14 as described above and sealed along one end at 15. When the time comes to complete the impregnation of the paper, the second package 13 is ruptured allowing the electrolyte 14 to complete the impregnation whereupon the paper is ready for use and the outer package 10 may be opened.
  • FIG. 4 shows a modified form of package in which the neck 16-26 from one part of the package to the other is closed by a first clamp 17-18-19-20 and a second clamp 22-23-24-25 or a dual clamp provided by connecting the two as at 27 leaving a small pocket 21 therebetween.
  • This third pocket may contain an indicator such as litmus compounds which changes color when in contact with the electrolyte. Thus, if any of the electrolyte leaks past one of the clamps, the indicator will change color showing that this leakage has taken place.
  • This provision is a means for showing the condition inside the two parts of the package.
  • FIG. 5 shows a paper roll 1 produced to be coreless, that is the inner opening 28 of the roll is mainly self-supporting.
  • end plugs 29 and 30 may be provided for mounting the paper roll in the recording machine. Where such end plugs are used, they are provided with openings 31 and 32 to permit electrolyte to pass into the inside of the roll to speed impregnation.
  • 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.
  • an electrolyte including a marking compound along with a
  • 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 l 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 v predetermined liquid content to said electrolytic recording paper in combination with said predetermined moisture content contained in the second of said parts.
  • a salt chosen from the l 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
  • an electrolyte comprising a marking compound, a stabilizer, a wetting agent and sufficient water to provide a v predetermined liquid content to said electrolytic
