Patents by Inventor Carlos A. Salvado

Carlos A. Salvado 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: 5095442
    Abstract: The weight fractions of the phases of a composite material working specimen are determined nondestructively by first performing a sufficient number of nondestructive and destructive calibration measurements on the properties of calibration specimens. The information learned from the calibration specimens is used in combination with nondestructive measurements of the working specimen to determine the fractions of the phases therein, without damaging the working specimen. In one version of this approach, ultrasonic measurements are used to determine fractions of the fiber and matrix in a nonmetallic composite material.
    Type: Grant

  • Patent number: 4961346
    Abstract: An apparatus for performing ultrasonic measurements of compliant material specimens includes a pair of facing but spaced apart ultrasonic transducers between which the specimen is placed, and which transmits signals into the specimen and receives signals from the specimen, a structure which presses the transducers against the opposite surfaces of the specimen with a reproducibly controllable force so that the same compressive force may be applied for successive measurements, a gauge that measures the separation of the two transducers, and a controller which drives the transmitting transducer and receives the signals from the receiving transducer. The apparatus permits the determination of comparable ultrasonic properties for different points on one specimen, and the determination of comparable properties of a number of specimens, by making the measurements under identical conditions.
