Abstract: A portable, pallet-mountable, remotely controlled deluge system provides a means for rapidly delivering a large quantity of a liquid to a region of hazardous materials or a fire. An accumulator, mounted, for example, on a pallet is charged with a quantity of water, aqueous film-forming foam, or other liquid quenching agent. The liquid is pressurized with an inert gas and the liquid is held in the accumulator by an electric/hydraulic valve. The valve is connected to a control panel which is wired to a remote control. The control panel also includes an antenna to receive a remote control signal by electromagnetic communication. The system provides a method of quickly getting a fire-fighting liquid or a deluging liquid to a scene of a fire or a hazardous waste spill without subjecting personnel to the hazard.

In a preferred embodiment, the capstan comprises a drive wheel that is enclosed within the pressure housing and the pressure housing is made up of a pair of seal plates or flanges with a seal ring between them. A drive shaft penetrates one of the flanges. This arrangement minimizes the size of a rotating seal in the pressure housing.

Abstract: A system and method of marking goods for authentication and tracking purposes is described. The system and method include a central control which enables the system. The method and system are accomplished in real time, affording manufacturers the ability to eliminate problems associated with counterfeiting and diversion which begin at the manufacturing site. A central control unit enables the system by providing an allotment of goods to a host unit. The host unit directs printing terminals to mark particular goods with specific information encoding symbols. Following marking, goods are scanned to insure proper marking and then packaged for shipment. Following marking, the goods can be checked by illuminating the symbols printed thereon and cross referencing this data with the host database by using a field reading unit.

Abstract: The present invention provides a blowout preventer in which a first set of hydraulic ports communicate with either side of a first piston coupled to a first piston rod, a second set of hydraulic ports communicate with either side of a second piston coupled to a second piston rod, and the first and second pistons and associated piston rods may be actuated independent of each other. Each piston rod is coupled to a ram, and preferably, the first piston rod is coupled to a pipe ram and the second piston rod is coupled to a slip ram. A feature of the present invention provides that all of these elements are contained within a single chamber extending laterally of and communicating with the bore of a BOP.

Abstract: Methods and apparatus for the disposal of solid particulate material in subterranean formations are disclosed. The invention is not limited to the disposal of oil field waste and therefore provides means and methods for the disposal of virtually any type of waste slurry stream. A slurry is formed at the surface of the earth by mixing the solid waste in particulate form with liquid and viscosifier thereby forming a slurry. A borehole is drilled into a selected injection formation and the slurry is pumped from the surface through the borehole and into the injection formation. Some surface pretreating of the slurry may be required including sizing of the particulate solids, adding weighting material, removing excessive amounts of oil and grease and diluting to reduce the level of radioactivity. The injection formation is preferably dipping in angle with respect to the horizontal and highly fractured.

Abstract: The present disclosure sets forth an adapter for installation on an automobile engine in lieu of a disposable cartridge filter. The adapter includes inlet and outlet fittings. The inlet and outlet fittings connect through a pair of flexible hoses to a raised filter housing installed at an elevated location in the engine compartment. The system also includes an oil reservoir which accumulates oil under pressure where the oil under pressure is stored until engine starting. This enhances lubrication within the engine at the upper portions thereof to avoid dry starting which occurs when the oil otherwise settles to the bottom of the engine. The reservoir in conjunction with the filter housing operates with selected valves and checkvalves so a hydrostatic head of oil pressure is achieved even when the engine is not operating.

Abstract: An architectural support comprised of various splines, key ways, and collars which interlock and when assembled form a complete unit. This unit may be used as an architectural support in the construction or fabrication of a table, display, cabinet, stand, and platform. This architectural support in the above items would be used as a table leg, support leg, or door pull. In addition, the architectural support could be used for decorative or aesthetic purposes.

Abstract: A well tender system for controlling, separating, storing and offloading well fluids produced from subsea hydrocarbon formations. The system comprises a vertically aligned series of tethered cylindrical tanks which are torsionally stabilized by flexible catenary production riser and export riser bundles, and serviced by separate catenary pipe bundles. Piles are secured to the seabed, each pile assembly being pivotally connected to a lower rigid tendon, which is in turn connected to tendons arranged about the periphery of the interconnected cylindrical tanks.

A layer of polycrystalline material, resistant to corrosive and abrasive materials, is disposed over the outer end portion of the metal carbide stud to form a cap. An alternate conic form has a flat tip face. A chisel insert has a transecting edge and opposing flat faces. It is also covered with a PDC layer.

Abstract: A sampler develops a digital representation of an analog signal at a predetermined sampling rate. The highest frequency of a period of samples is determined and, if sampling rate of the sampler exceeds the Nyquist rate, indicating oversampling, redundant sample points are discarded from the period and the reduced record is stored. A multiplicity of periods make up a recorded session. To reconstruct the original signal, a common time domain is determined and the reduced records are expanded based upon the common time domain.

Abstract: A system and method provide a low distortion hydrophone. A first known piezoelectric element is mounted so as to receive a pressure signal. A second piezoelectric element is provided with a means of receiving and enhancing the same pressure signal. Since a piezoelectric element is a capacitor, another capacitor is coupled in parallel with the second element to serve as a divider. The output voltage of the combination of the two elements is taken as the difference between the positive terminals of the two elements. Thus, the effect of the pressure enhancer and capacitance divider is to provide a difference in potential between the fundamentals from the two elements, while rendering the amplitude of the second harmonics equal. The two equal second harmonics cancel each other out at the output terminals, while retaining a useful fundamental for further signal processing.

Abstract: A pulsed rare gas photoionization detector apparatus is set forth and incorporates a closed chamber for receiving a carrier gas flowing there through between inlets and outlets, and the carrier gas is exposed to a pair of electrodes forming a spark across the chamber and through the carrier gas. One component of the carrier gas is a dopant which selected from a plurality of rare gases. The sample to be analyzed is injected into the closed chamber where it commingles with the carrier gas. One reaction involves the formation of selected dopant in an excited state, which upon decay, serves as a source of ionizing radiation which reacts with sample compounds producing detectable events. These events are used to identify and quantify unknown compounds contained in the sample. The methods and apparatus are especially useful in selectively ionizing the compounds to be measured while not ionizing other constituents of the sample. This greatly enhances the signal-to-noise ratio for detecting impurity compounds.
