  • Controllable seismic source
    Patent number: 9146328
    Abstract: An apparatus for generating seismic waves includes a housing, a strike surface within the housing, and a hammer movably disposed within the housing. An actuator induces a striking motion in the hammer such that the hammer impacts the strike surface as part of the striking motion. The actuator is selectively adjustable to change characteristics of the striking motion and characteristics of seismic waves generated by the impact. The hammer may be modified to change the physical characteristics of the hammer, thereby changing characteristics of seismic waves generated by the hammer. The hammer may be disposed within a removable shock cavity, and the apparatus may include two hammers and two shock cavities positioned symmetrically about a center of the apparatus.

  • Alkylcellulose and salt compositions for dust control applications
    Patent number: 8945667
    Abstract: A method of reducing dust generation from an aggregate surface is described. The method includes applying a dust suppression compound to the aggregate surface. The dust suppression compound may be made from an aqueous mixture of an alkylcellulose compound and a halogen containing salt.

  • Citrate containing deicing compositions with improved eutectic temperatures
    Patent number: 8808572
    Abstract: Deicing compositions are described for reducing an amount of ice formed on a surface. The deicing compositions may include about 1 wt. % to about 15 wt. % of a salt of citric acid. The compositions may further include about 23 wt. % to about 28 wt. % sodium chloride when the deicing composition forms an aqueous solution.
