Definitions

  • This invention relates to a sheet having transferable coating containing magnetizable material, and more particularly pertains to such a sheet through which a marking impression may be made and in the coating of which the magnetizable material is present in small particle form as a dispersion in a waxy medium.
  • Such a sheet is usefu as a means for transferring magnetizable spots or magnetized spots to record material, such spots by their location or number on a piece of rec ord material representing selected data.
  • record material with unmagnctized spots is disclosed in application for United States Letters Patent, Serial No. 97,222 of Konrad Collins, filed June 4, 1949, now abandoned, and a method of using such record material is disclosed in application for United States Letters Patent, Serial No. 102,843, of the same Konrad Rauch, filed July 2, 1949, now abandoned.
  • novel sheet of this invention is used in a manner similar to the way carbon transfer paper is used, that is, it is placed, coated side down, on top of the coated sheet at points where marks are to be left on the record sheet, a portion of the coating being transferred to the record material because of the applied pressure.
  • the transferred coating material has carried therewith the proportionate amount of the dispersed magnetizable substance, be it in the magnetized or unmagnetized condition. If the particles are in magnetized condition in the transfer sheet the particles transferred to the record sheet will remain so, as the transfer of materials is made by pressure or impact forces, such as would occur through use of a stylus or a type member, which will not disturb the orientation of the particles suliiciently to seriously interfere with the mass effect.
  • the magnetization of the sheet should, to get best results, be made with the poles of all the magnetized particles oriented in the same direction parallel with plane of the sheet and not perpendicular to it. This may be easily done by drawing a magnet across the front or rear surface of the sheet.
  • Another object of the invention is to provide such a coated sheet with the particles normally unmagnetized therein.
  • Another object of the invention is to provide such a coated sheet with the particles normally magnetized therein.
  • Tin. pref :red sheet used a to which the coating is applied, is paper, although other thin sheeting whether of woven or film construction, and through which a printing or marking impression may be made, may be used. For example, finely woven cloth or cellulose acetate film may be used instead of paper.
  • the preferred coating waxy base is made of the fol lowing ingredients: petrolatum having a melting point of between and Fahrenheit, an apparent viscosity at 80 Fahrenheit of between 2500 and 4500 Saybolt Universal seconds at a rate of shear of 1200 reciprocal seconds, and a neutralization number of 0.05 as determined by American Society for Testing 1V aterials method; parathn wax having a melting point of between 125 and 30 Fahrenheit; vegetable fiber wax having a melting point of approximately 173 Fahrenheit, a saponiiication number of approximately 65 and an iodine number of 20 to 30; yellow beeswax having a specific gravity of 0.95 to 0.97 at centigrade, a melting point of be tween 62 and 65 centigracie, an acid value of between 17' and 24, a saponilication value of 87 to 104, and an ester value of 70 to 80, all as determined by the U.
  • petrolatum having a melting point of between and Fahrenheit, an apparent
  • magnetizable particles which, preferably, is in the form of finely powdered magnetic iron oxide, finely powdered iron, or both.
  • the waxy base will hold and still retain its coating and transfer characteristics.
  • About 50 pounds of either iron oxide or iron powder may be incorporated in the above mentioned 30.1 pound batch of the waxy base.
  • the proportions of magnetizable material and waxy base may vary considerably from this figure.
  • the magnetic iron oxide may be magnetized while in the coating and so transferred in the magnetized state to the record material to be marked. Such marks may be sensed as magnetic spots by standard pick-up appart tus in which such merits generate a current as they pass over the poles of an electromaguet.
  • the unmagnetized iron oxide marks may be magnetized on the record material before being so sensed.
  • the iron powder marks, while they may not be sensed as a magnetic spot, may be sensed as areas of increased magnetic permeability.
  • the magnetizable par"cle size measured by diameters, preferably is or" the order of 1 to 5 microns.
  • the coating is applied to the sheet hot by means of a coating machine like those used for carbon transfer coating.
  • this transfer coated sheet finds its primary use as a carrier of magnetizable material to be transferred to record material by pressure or impact.
  • a transfer sheet including,
  • a base sheet through which a printing or marking impression may be made; and a pressure-transferable magnetizable coating on a surface thereof, which may be locally transferred by placing the transfer sheet onto an undersheet so the transfer sheet coating is in contact therewith and making a printing or marking impression through said transfer sheet, and said coating being of waxy material having dispersed therein fine particles of magnetizaole material, the magnetizable material being of microscopic particle size and constituting the major portion by Weight of the weight of the entire coating.
  • material includes particles of iron, ranging from 1 to 5 microns in diameter.
  • a sheet through which a printing or marking impression may be made said sheet having coated on a surface thereof a waxy substance having dispersed therein microscopic particles of magnetizable material, said Waxy substance and contained magnetizable material being transferable locally by a printing or marking impression applied to the sheet.
