Definitions

  • a microfilm index card wherein a rectangular sheetlike carrier supports several rows of microcopies each of which has an exposed information-bearing portion and an unexposed portion.
  • the unexposed portions of the microcopies are connected with the carrier by ultrasonically welded spots which allow for detachment of microcopies without damaging the carrier.
  • the emulsion sides of themicrocopies face away from the carrier to permit the placing of such sides into immediate proximity of photosensitive layers during contact printing.
  • the spots are strong enough to normally prevent turning or other movements of microcopies with reference to the carrier.
  • microcopies in 18x24 or mirofiche size are obtained by stepwise exposure of successive documents on discrete sheets of film or by a continuous microfilming method.
  • an elongated roll of microfilm can be exposed stepwise or continuously to store information in the form of negative microframes or microcopies, and the roll is thereupon subdivided into strips of to 12 frames each.
  • strips are thereupon mounted on a card by resorting to self-adhesive tape.
  • the cards may have openings or cutouts for the exposed microfilm frames.
  • An object of the invention is to provide a novel and improved microfilm index card with a plurality of microcopies.
  • Another object of the invention is to provide novel and improved connections between a sheet-like carrier and a plurality of microcopies.
  • a further object of the invention is to provide a microfilm index card with connections which secure microcopies to a sheet-like carrier in such a way that the microcopies are safely retained in desired orientation but can be readily detached without damaging the carrier.
  • An additional object of the invention is to provide an index card wherein a large number of microcopies can be stored in a small area and wherein the connections between the microcopies and the carrier do not affect the quality of information which is stored on the microcopies.
  • the improved microfilm index card comprises a sheet-like carrier, at least one row of sheet-like microcopies or microframes on the carrier, and spots of ultrasonically welded connections between the carrier and the microcopies.
  • Each microcopy preferably comprises an exposed information-bearing portion and an unexposed portion, and the spots of welding connect the carrier with the unexposed portions of the microcopies.
  • the emulsion side of each microcopy preferably faces away from the carrier to facilitate accurate contact printing.
  • the connections formed by the ultrasonically welded spots will not deteriorate on prolonged storage of the index card.
  • the drawing illustrates a microfilm index card which comprises a rectangular sheet-like carrier 1 and several parallel rows of sheet-like microcopies or microframes 3 which are separably but safely secured to the carrier 1 by circular ultrasonically welded spots 2.
  • the carrier 1 may consist of transparent material and each microcopy 3 comprises an exposed information-bearing portion 3a and an unexposed portion 3b.
  • the spots 2 connect the carrier 1 with the unexposed portions 3b.
  • spots 2 By properly positioning and adjusting the ulrasonic welding apparatus, one can form spots 2 of required size and depth to thus insure that the microcopies 3 are held against turning with reference to the carrier 1, i.e., that the microcopies remain in a desired orientation in which a substantial number of such microcopies can be stored on a relatively small carrier.
  • the spots 2 allow for repeated separation of selected microcopies 3 without any damage to the carrier 1.
  • a fresh spot 2 is provided whenever a previously separated microcopy 3 is to be reattached to the carrier 1 in a selected position. This allows for convenient detachment of one or more selected microcopies for the purpose of viewing in a reader or for reproduction of information on their exposed portions 3a.
  • microcopies 3 mount the microcopies 3 on the carrier l in such a way that their emulsion side faces away from the carrier. This is advisable when the information on the microcopies 3 is reproduced by contact printing because the emulsion side can be placed into immediate proximity of the photosensitive layer on a sheet or roll of printing paper. Such positioning of microcopies during contact printing insures the making of highly satisfactory prints with sharply outlined details of the information which is stored on the microcopies.
  • a microfilm index card comprising a sheet-like carrier having a rectangular outline and consisting of a light-transmitting material; a plurality of groups of sheet-like microcopies on said carrier, each of said changed at will.
