  • Publication number: 20130339545
    Abstract: This invention relates to the use of optimal (hyperspeed) paths for command and control (and other high priority) traffic and suboptimal (slower) paths for all other traffic in order to implement sophisticated network service differentiation and defensive techniques. A reaction time window is created to ensure that packets sent along hyperspeed paths can arrive sufficiently in advance of malicious traffic in order to alert network devices and initiate defensive actions. Assortments of defensive options are available to networks employing the invention and the inventive algorithms.

  • Patent number: 8574744
    Abstract: A three-dimensional nanobattery formed by individually wiring nanostructured electrodes and combining them with an electrolyte. Short, capped nanotubes termed ‘nanobaskets’ are formed by sputtering coating onto nanoporous templates. Metallic nanowires are grown by electrochemical deposition from the nanobaskets and through the template, making electrical contact with each nanobasket electrode. The same procedure can be used to fabricate both a battery anode and a battery cathode. A thin layer of electrolyte is placed between the two nanobasket electrodes, and electrical contact is made through the nanowires.

  • Patent number: 8419931
    Abstract: The current invention provides an improved petroleum coking process wherein the risk of silicone poisoning of units downstream of the coke drums is eliminated. The method of the current invention controls the foam layer within the coke drum by injection of a non-silicone anti-foam agent, preferably a tire oil. In another embodiment, the current invention provides a controlled foaming method which increases the liquid production from the coke drum. In the controlled foaming method, an anti-foam agent is cyclically injected into the drum early in the coke drum fill cycle. The cyclic injections manage the foam layer without inducing the induction phase in the coke feedstock, thereby increasing the total volume of feedstock received by the coke drum.

  • Patent number: 7740028
    Abstract: A composite plug system and a process to repair a hole in a tubular pipe. The process includes the steps of inserting a fastener through an opening in an oblong inner plate having an elongated diameter and a shorter diameter. The oblong plate is inserted into the pipe hole wherein the elongated diameter is greater than a diameter of the pipe hole and wherein the shorter diameter is less than the pipe hole diameter so that the oblong plate is within the tubular pipe beneath the hole. An initially liquid adhesive filler is applied over the oblong inner plate over the pipe hole. An outer plate having a central opening and a diameter larger than the pipe hole diameter is affixed over the pipe hole so that the central opening receives the fastener. The outer plate is secured to the oblong inner plate and the tubular pipe with the fastener until the adhesive filler solidifies. After the filler solidifies, the oblong plate and the outer plate are structurally bonded to the pipe wall through adhesion.

  • Patent number: 7736724
    Abstract: A method of producing a nanobasket and the applications or uses thereof. The method includes the steps of providing a substrate with at least one (1) pore having diameters of about one (1) nanometer to about ten (10) micrometers. Material is deposited by sputter-coating techniques along continuous edges of the pores to form a capped or partially capped nanotube or microtube structure, termed a nanobasket. Either a single material may be used to form nanobaskets over the pores or, alternately, a layered structure may be created wherein an initial material is deposited followed by one or more other materials to form nanobaskets over the pores.

  • Patent number: 7616524
    Abstract: A wavelet-based method for improving the quality of seismic data utilizing the intercept determined by applying least squares regression to the wavelet transform of a seismic trace. The intercept is calculated for every time point of the wavelet transform for each seismic trace. The intercepts are then plotted versus time or depth. These plots are used in place of seismic traces themselves to create two dimensional and three dimensional seismic section images. In one embodiment, the real and imaginary portions of the selected wavelet transform are weighted to generate a finer representation of the intercept. In another embodiment, a minimum amplitude value is utilized to establish a noise floor, thus stabilizing the regression calculation. In yet another embodiment, a taper of the amplitude is applied to wavelet enhance the resolving power of the wavelet.

  • Patent number: 7601426
    Abstract: An intumescent coating in the form of an initially liquid coating which cures to a solid and adheres to a substrate. The coating includes a flexible thermosetting epoxy, such as diglycidyl ether of bisphenol-A (DGEBA), with an aliphatic amine curing agent, expandable graphite flakes with reagent chemicals that react upon heating and decompose into gaseous products, and fumed silica. In the presence of heat or flame, an intumescent layer develops at the coating surface, insulating the substrate. The coating is found to add intumescent characteristics which provide heat resistant and fire retardant qualities.

  • Patent number: 7546880
    Abstract: A process for extracting hydrocarbon gases from marine sediment hydrates. In one embodiment, the process includes drilling from a sea floor into a hydrate rich subsea sediment to form at least one opening therein. Electrical heaters are inserted into the opening or openings. The hydrate rich subsea sediment is heated with the electrical heaters in order to release hydrocarbon gas therefrom. The released hydrocarbon gas is collected in an overhead receiver. The hydrocarbon gas forms hydrates again when moving through the cold sea water and inside the overhead receiver. The overhead receiver is raised to a sea depth where pressure and temperature permit the hydrates to dissociate and to release the hydrocarbon gas. The hydrocarbon gas is then gathered from the top of the overhead receiver.

  • Patent number: 6807849
    Abstract: An apparatus and process to generate a liquid-gas-surfactant foam and to measure its viscosity and enable optical and or electronic measurements of physical properties. The process includes the steps of pumping selected and measured liquids and measured gases into a mixing cell. The mixing cell is pressurized to a desired pressure and maintained at a desired pressure. Liquids and gas are mixed in the mixing cell to produce a foam of desired consistency. The temperature of the foam in the mixing cell is controlled. Foam is delivered from the mixing cell through a viscometer under controlled pressure and temperature conditions where the viscous and physical properties of the foam are measured and observed.

  • Patent number: 6745129
    Abstract: A wavelet-based method for analysis of singularities improves analysis and information gathering from seismic trace data. A wavelet transform is applied to seismic trace data. The Hölder exponent is calculated for every time point of the wavelet transform for each seismic trace. Hölder exponents are then plotted versus time. These graphs are utilized in place of seismic traces themselves in creating two and three dimensional images. The graphs produced using Hölder exponents greatly improve interpretation of stratigraphic boundaries and other geological information to be readily identified. This provides for better, more accurate stratigraphic analysis. In addition, the nature of the Hölder exponents of the seismic trace are consistent with Hölder exponents calculated from acoustic impedance of the various strata.
