Patents by Inventor Geiza Esperandio de Oliveira

Geiza Esperandio de Oliveira 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: 11739193
    Abstract: The present invention refers to a polymer composite that comprises sand preferably medium, at least a load, at least a resin selected from among dicyclopentadiene polyester resin (DCPD) and resin PET and at least a phase-compatibilizing additive and/or flexibilizing agent of the polymer structure. Further, the present invention refers to process of preparing said composite besides the use of said composite for preparing some articles including sleepers. This composite presents several advantages when compared to the materials used today for preparing sleepers as it is more versatile than steel, more available and as effective as wood, more durable than the concrete as it comprises an optimized composition that combines ideal physical-chemical properties to exercise the function for which it was intended.

  • Patent number: 10323513
    Abstract: An apparatus for estimating an ambient environment at which organic scale will form in a downhole fluid includes a stress chamber disposed in a borehole in a production zone at a location of maximum pressure and configured to receive a sample of the fluid from the production zone and to apply an ambient condition to the sample that causes the formation of organic scale. A sensor is configured to sense formation of organic scale within the chamber and an ambient environment sensor is configured to sense an ambient environment within the chamber at which the formation of organic scale occurs. The apparatus further includes a processor configured to receive measurement data from the organic scaling sensor and the ambient environment sensor and to identify the ambient environment at which the formation of organic scale occurs using the organic scaling sensor measurement data and ambient environment sensor measurement data.
