Leonard Holley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5508343
    Abstract: An antistatic composition comprising an admixture of a water soluble polymer of a quaternary ammonium salt and a an amino or sulfonyl titanate or zirconate composition. The titanate or zirconate composition is present in the admixture in an amount sufficient to reduce the moisture sensitivity of the quaternary ammonium salt polymer while retaining its antistatic properties. The antistatic properties of the composition are greater than the additive antistatic properties of the polymer and the titanate or zirconate composition. An associated method and coated antistatic surface are also disclosed.
    Type: Grant

  • Patent number: 5491013
    Abstract: An electrostatic dissipating packaging tape is disclosed that comprises a transparent substrate, a substantially transparent adhesive layer on one surface of the substrate, and a clay coating on the opposite surface of the substrate from the adhesive. The clay is characterized by being able to provide a surface resistivity of 10.sup.14 ohms per square or less when present on a surface in amounts that are low enough to remain transparent, and the clay is present on the substrate surface in an amount sufficient to provide the coating with a surface resistivity of 10.sup.14 ohms per square or less, but less than an amount that would substantially reduce the transparent optical properties of the packaging tape.

  • Patent number: 5447784
    Abstract: A transparent static dissipative adhesive tape is disclosed. The tape comprises a transparent polymer substrate having opposed first and second surfaces, a transparent static dissipative coating on the first surface of the substrate, and a transparent static dissipative adhesive coating on the second surface of the substrate. The adhesive coating comprises a transparent conductive layer on the second surface formed of conductive particles in a polymer matrix, and a transparent adhesive layer without any conductive particles over the conductive layer. The exposed surface of the adhesive layer exhibits conductivity substantially the same as the conductivity of the underlying conductive layer.

  • Patent number: 4458461
    Abstract: A partitioning system includes a plurality of support posts between which are carried partitions or panels. The support posts have slots therein into which key members positioned on the ends of the panels or partitions may be placed. At each end of the support posts are provided key caps which also include slots into which part of the key members may be positioned.
