A composition of matter and a method of sealing a permeable formation is provided incorporating the composition to reduce or eliminate lost circulation in permeable formations. The composition comprises one or more sealing components, ranging in size from approximately 10 to approximately 750 microns, a wetting component, a viscosifier component and an activator or flocculant. A dry mixture of the components may be added directly from the bag to the drilling mud to the permeable formation and will not set up inside the drill string. The mixture will seal the formation in an aqueous or organic environment, thus removing the need to form a pill in a slugging pit prior to introduction. The mixture dewaters at a rapid rate without regard to the time and temperature required for curing agents or other additives. The mixture does not require additional agents such as defoamers, accelerators, retarders or spacers to dewater and set as a solid plug.

A method and an apparatus for advantageously introducing a flame and a high velocity oxidizing gas into a furnace for metal melting, refining and processing, particularly steel making in an electric arc furnace. The steel making process of an electric arc furnace is made more efficient by shortening the time of the scrap melting phase and introducing an effective high velocity oxidizing gas stream into the process sooner to decarburize the melted metal. In one implementation of an apparatus, improved efficiency is obtained by mounting a fixed burner / lance closer to the hot face of the furnace refractory at an effective injection angle. This mounting technique shortens the distance that the flame of the burner has to melt through the scrap to clear a path to the molten metal and shortens the distance the high velocity oxygen from the lance travels to the slag-metal interface thereby increasing its penetrating power. The method additionally includes supplying a plurality of reaction zones with the high velocity oxidizing gas to decarburize the melted metal. The plurality of reaction zones increases the surface area available for the reaction thereby allowing a more rapid rate of decarburization and a more homogenous metal bath. The reaction zones are supplied with the high velocity oxidizing gas according to an oxygen supply profile which is related to the carbon content of the metal bath. In this manner an optimal amount of oxygen can be introduced into the metal bath to shorten the decarburization process without producing excessive oxidation of the metal bath and excessive free oxygen in the furnace.

Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.

The system and method autonomously and selectively jams frequency-hopping signals in near real-time by incorporating a fundamental change in the detection and reaction technology, to provide a reaction time that is short enough, within milliseconds or less, to capture and then jam even the fastest frequency hopping radios in use today, without relying on prior art methods of using standard CPU driven technology.The system automatically determines if detected signal(s) should be jammed, and subsequently to automatically end extremely quickly activates the jamming transmitter on the frequency-hopper transmitter's frequency. Finally, the system provides a programmable user interface so that operators can set up the system to act autonomously as intended, such that operator intervention is unnecessary when the system is placed in jamming operation mode.
