    Abstract: The invention teaches means for detecting unauthorized tampering or substitutions of a device, and has particular utility when applied on a "seal" device used to secure a location or thing. The seal has a transparent body wall, and a first indicia, viz., a label identification is formed on the inside surface of this wall. Second and third indicia are formed on the outside surface of the transparent wall, and each of these indicia is transparent to allow the parallax angled viewing of the first indicia through these indicia. The second indicia is in the form of a broadly uniform pattern, viz, many small spaced dots; while the third indicia is in the form of easily memorized objects, such as human faces, made on a substrate by means of halftone printing. The substrate is lapped over the outside surface of the transparent wall.

  • Patent number: 4197982
    Abstract: A device for closing and sealing bags which eliminates the tightening of the mouth, and makes the operation simple, rapid and safe. The device, according to the invention, comprises a flat housing with an open bottom which receives the folded mouth (preferably two series of folds reminiscent of an accordion) of a bag. An element is extended between the two larger sides of the housing, passing through aligned orifices in the folded mouth of the bag. This effects immobilization between the element and the two larger sides. In the preferred embodiment, the element is, in reality, two lengths of cord fixed to one of the larger sides and freely passing across the other. In this case, the larger sides form part of two halves of the housing, which are separable for opening the bag. In the closed position, the two halves can be locked and sealed.

    Abstract: The invention is directed to a security device which detects tampering with secured closure. A fiber optic bundle is looped through a closure and secured at opposite ends of the bundle to a snap-together connector. An intermediate length of the fiber optic bundle surrounds the snap-together connector preventing access to its locking mechanism unless fibers are severed. After installation, light is passed through the fiber optics and a particular pattern is generated at a viewing end of the connector. Tampering with the closure will cause individual fiber optics to be disturbed or cut so that subsequent viewing of the fiber optics will generate a different viewing pattern than originally observed.

  • Patent number: 4118057
    Abstract: A reusable, tamper-indicating seal comprises a drum confined within a fixed body and rotatable in one direction therewithin, the top of the drum constituting a tray carrying a large number of small balls of several different colors. The fixed body contains parallel holes for looping a seal wire therethrough. The base of the drums carries cams adapted to coact with cam followers to lock the wire within the seal at one angular position of the drum. A channel in the fixed body -- visible from outside the seal -- adjacent the tray constitutes a segregated location for a small plurality of the colored balls. A spring in the tray forces colored balls into the segregated location at one angular position of the drum, further rotation securing the balls in position and the wires in the seal. A wedge-shaped plough removes the balls from the segregated location, at a different angular position of the drum, the wire being unlocked at the same position.
