  • Patent number: 6467382
    Abstract: An extraction apparatus for extracting or separating cut or partially cut pieces or parts from a cut sheet at an extraction station comprises: a sheet gripping and moving device for gripping and moving a cut or partially cut sheet through an extraction station; and an extraction roller at the extraction station positioned for movement transversely of a cut sheet and being constructed, arranged and operated to move transversely of the path of movement of the cut sheet when the leading edge scrap web of the cut sheet is adjacent the extraction roller to engage and deflect the scrap web of the cut sheet passing through the gripping and moving device away from the cut pieces or parts.

  • Patent number: 4429217
    Abstract: Apparatus and method of verification of credit cards, including sensing information thereon and comparing said information with information on a specially designed pre-printed carrier, followed by insertion of one or more cards in the matching carrier as required, folding and stacking card-inserted carriers in a manner ready for subsequent insertion into mailing envelopes. Sensing, input, comparison logic, and timed command circuitry for coordination of operation includes a pause mode of card advance and may optionally include a multiple card search mode to find matching cards when card sequence is improper.

  • Patent number: 4215813
    Abstract: Device and method for reading indicia embossed, punched or impressed in a sheet of base material, such as credit-type cards and the like. The reader employs a head having a plurality of movable fingers disposed to sense the holes or embossing when the card is moved relative to the head. The fingers carry light guides thereon which are spaced from and disposed to transmit light from a fixed source. A light cut-off shield is disposed between the source of the light and the light guides to intercept and prevent or permit transmission of the light when the fingers pass over the embossed indicia or holes. Light detectors are disposed at the opposite terminus of the light guides to detect the presence or absence of light and produce electrical pulses corresponding thereto. These electrical pulses can be used or processed in any circuitry as information input correlating to the indicia on the base material, e.g.

  • Patent number: 4034210
    Abstract: Single-sheet, multi-panel carriers for receiving and retaining credit cards during credit card issue and mailing procedures. Cards may be inserted in the carriers manually or by machine. Plural carrier forms are preferably provided in a continuous fan-folded web, and individual carriers are separable therefrom at perforations between subsequent and/or adjacent carriers. The carriers have special slits or slots for retaining one to four cards singly, or double that in a piggy-back manner, in vertical or horizontal configurations. Carriers also have a plurality of panels which assist in retaining the cards by wedge trapping during manual or machine issue processing (inserting, collating, verification and stuffing) and mailing operations. Carriers also carry verification and/or identification information thereon relating to the account, e.g.
