- A sealant and a methodIntellectual Property Available to LicenseUS Patent 7,438,755 B2
- Chemically Bonded Phosphate Ceramic Sealant Formulations for Oil Field Applications (IN-02-045)
A sealant for an oil or geothermal well capable of setting within about 3 to about 6 hours at temperatures less than about 250° F. for shallow wells less than about 10,000 feet and deep wells greater than about 10,000 feet having MgO present in the range of from about 9.9 to about 14.5%, KH2PO4 present in the range of from about 29.7 to about 27.2%, class C fly ash present in the range of from about 19.8 to about 36.3%, class F fly ash present in the range of from about 19.8 to about 0%, boric acid or borax present in the range of from about 0.39 to about 1.45%, and water present in the range of from about 20.3 to about 21.86% by weight of the sealant.
A method of sealing wells is disclosed as are compositions for very high temperature wells is disclosed as is a composition for treating oil field wastes.
- Cryoloop auto-centering for crystal location and alignment to an x-ray beamIntellectual Property Available to LicenseUS Patent 7,438,472 B1
- Automatic Cryoloop Alignment for Protein Crystals (IN-06-117)
Methods and apparatus for implementing robust and efficient cryoloop auto-centering for crystal location and alignment to the x-ray beam are provided. Image processing techniques are used for recognition of the small protein crystals. The detected crystal location enables crystal positioning in the x-ray beam, and optimization of the x-ray optics such as beam profile and intensity to the size and shape of the protein crystals.
- This is the first demonstration of an “autonomous” frequency source that can maintain a constant frequency and vibrating amplitude when no external power is provided, making it ideal for applications requiring an oscillator in low power, or limited and inIntellectual Property Available to LicenseUS Patent 9,680,414 B1
- Frequency and Amplitude Stabilization in MEMS and NEMS Oscillators (IN-15-101)
This invention comprises a nonlinear micro- and nano-mechanical resonator that can maintain frequency of operation and amplitude of operation for a period of time after all external power has been removed from the device. Utilizing specific nonlinear dynamics of the micromechanical resonator, mechanical energy at low frequencies can be input and stored in higher frequencies modes, thus using the multiple degrees of freedom of the resonator to extend its energy storage capacity. Furthermore, the energy stored in multiple vibrational modes can be used to maintain the resonator oscillating for a fixed period of time, even without an external power supply.
