  • Reproduction of holograms
    Patent number: 5227897
    Abstract: A multidimensional, visually readable, diffractive surface grating such as a hologram is reproduced by providing a master grating, generating a negative image plate from the master grating for insertion into a forming device, and replicating the master grating in plasticizable material in the forming device so as to provide a directly visually readable grating.
    Type: Grant

    Inventors: Scott R. Fohrman, Steven L. Smith
  • Flexible multiple compartment drug container
    Patent number: 5176634
    Abstract: A flexible container is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments, separated by frangible seals, in which the diluents and medicaments are stored. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through a standard IV arrangement to a patient.

  • Method and apparatus for producing full color stereographic holograms
    Patent number: 5134504
    Abstract: A method and apparatus for producing temporally coherent, full color holograms is disclosed whereby a linear array of stereographically positioned cameras are simultaneously triggered to obtain a temporally coherent sequence of full color exposures. The exposures are then sequentially exposed upon an H1 plate using multiple wavelength, "white" laser light to obtain a virtual full color hologram image in a single step operation.

  • Multiple layer packaging films and packages formed thereof
    Patent number: 4910085
    Abstract: The invention discloses a multiple layer film useful in packaging, and the packages made therefrom. A first layer of the film is a material containing an ester group, a polycarbonate or a polyether block amide copolymer. A second layer of the film is a sealant, preferably polypropylene polymer blended with an elastomeric styrene ethylene butylene styrene copolymer. A third functionally adhesive layer is between the first and second layers. The composition of the third adhesive layer is typically either a polypropylene modified with a carboxy group such as an organic acid or anhydride or a styrene ethylene butylene styrene copolymer.
