Abstract: A business form, which may be a tag, label, ticket, identification card, or the like, comprising a base sheet adapted to receive writing or printing and a transparent sheet having adhesive by which it can be laminated to the base sheet, and a liner sheet covering the adhesive. A removable carbon paper or other sheet lying between the liner and base sheets is secured to the former whereby removal of the carbon sheet automatically causes the liner sheet to be pulled off and removed and the transparent sheet to be applied to the face of the base sheet.

Abstract: An apparatus and method for making single crystals of a high melting point substance by a crucibleless skull process are provided wherein the apparatus operates with less power consumption than comparable prior art systems. The apparatus utilizes a self-sealing and self-venting charge comprising a mass of the substance with a preformed vent therein, the mass being held and retained by a side wall made of a felt of the substance. The charge is retained by an encircling plurality of rods comprising a nonsusceptible material. The charge is heated by RF induction from the center of the charge to form a melt which extends outward. The melt is extended longitudinally by translating the charge in the RF field.

Abstract: A ribbon cartridge for use in combination with a printing machine having a ribbon quantity sensor for reversing the direction of ribbon movement is provided. The cartridge has at least two spools therein with an inked ribbon attached to each spool and includes means for immobilizing both of the spools and means for locking each of the spools in a preferred position for insertion into the printing machine.

Abstract: A batch reading system for automatically reading documents such as tags or tickets having data marked thereon in the form of human readable characters which are also automatically readable by suitable apparatus, the system being capable of feeding documents which are curled, wrinkled, bent, and otherwise deformed or mutilated. The documents are fed from an input hopper by first feed means, which may be a vacuum belt, from which they are fed to a second vacuum belt on whose underside the tags are held and fed past an underlying automatic reading device. The documents which are properly read are each stripped from the overlying vacuum belt by a flipper arm into a discharge chute, while other tickets are fed past the discharge chute to a reject stacker. To accurately laterally position the documents being fed, one of their longitudinal edges is pressed against a reference surface.

Abstract: System for printing particular information-bearing symbols corresponding to data emanating from a source comprising: source means capable of generating data in a particular sequence; memory means for storing information-bearing symbols; selection means for selecting particular symbols from said memory means corresponding to data emanating from said source; said selection means ordering said particular symbols in a predetermined sequence for printing; a medium adapted to bear printed information-bearing symbols; and transmitting means for transmitting each of said particular characters from said memory means to said medium.

Abstract: A ribbon cartridge is adapted for insertion into a printing machine such as a printing electronic calculator having a printer, a platen, and a ribbon quantity sensing and reversing lever. The cartridge comprises a cassette with an inked ribbon therein connected between two ribbon storage members. The cassette has ribbon guide members for directing the ribbon from one ribbon storage member in between the printer and platen to another ribbon storage member. The ribbon cartridge is improved by incorporating as a part of the cassette a member or members for moving the lever into a non-interfering position during the insertion of the cartridge into the printing machine, the member(s) being positioned below the operating plane of the lever upon complete insertion of the cartridge.

Abstract: A label manufactured from sheet-shaped material, comprising a first part destined for bearing information and a second part connected with the first part and destined to be secured to an article, characterized in that the second part consists of a strip of sheet-shaped material provided with a plurality of incisions extending substantially in the longitudinal direction.

Abstract: An improved manually actuatable electric keyboard switch and retainer capable of being easily removed and reoriented or replaced to provide a different function.

Abstract: A driving device for a print head including printing mechanism actuated at predetermined times for marking characters on a data carrier carried by a print roll, comprising motion converting mechanism comprising a housing including an interior continuous gear path, said housing being coupled to said print head; said gear path comprising a pair of opposing straight path portions substantially parallel to the axis of said print roll; said straight path portions being joined, at each end thereof, by respective curved path portions; rotatable pinion mechanism in continual engagement with said gear path; said pinion mechanism being coupled to the shaft of a motor driving mechanism; said straight path portions being mutually separated by a distance greater than the outside diameter of said pinion mechanism and said curved path portions being mutually separated by a distance substantially greater than the distance separating said straight path portions; rotary motion of said pinion mechanism being converted to recipr

Abstract: A method of graphic data redundancy reduction in an optical facsimile system wherein picture elements are optically represented by a grey coded number having N digits where N is at least 5 comprising evaluating at least the first N-2 bit planes to determine whether these bit planes should be processed in high or low resolution, and arbitrarily processing the remaining at least one bit plane at low resolution.

Abstract: A matrix print head comprising a plurality of electromagnets each having an associated armature; a plurality of elongated print elements having ends adapted for printing markings on a data carrier; each of said print elements being associated with an armature; each of said print elements including a straight-line portion substantially perpendicular to said data carrier; said print element straight line portions being parallel to each other and being disposed in the same plane each of said print elements including an armature-engaging portion for resiliently maintaining its associated armature against its associated electromagnet, each of said print element armature-engaging portions permitting its associated armature to pivot about a first surface of its associated electromagnet whenever said electromagnet is energized, whereby the associated print element is thereby moved in a direction parallel to the straight-line portion thereof to thereby permit a marking on said data carrier to be printed.
