  • Patent number: 5600075
    Abstract: The present disclosure sets out a sample collection system which involves a single valve having six ports and two positions. The valve is operated to isolate two ports so that the system process flows into the valve. In the other position of the valve, a sample loop is filled. The sample loop includes a sample storage container. The sample loop connects with the container through quick disconnects and separate isolation valves.

  • Patent number: 5599004
    Abstract: A method and apparatus for the installation of cable into a reel of coiled tubing includes a cable injector. The cable injector comprises a capstan drive within a pressure housing. 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.

  • Patent number: 5592561
    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.

  • Patent number: 5590867
    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.

  • Patent number: 5584158
    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.

  • Patent number: 5549070
    Abstract: The present invention provides a simple system for in-water dry docking pleasure boats using existing boat slips. The system includes a dry-dock basin having a pair of ballast tanks mounted below the bottom surface of the basin. The basin is submerged using guide pipes below the boat slip where the boat is typically stored.

  • Patent number: 5549164
    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.

  • Patent number: 5544713
    Abstract: A cutting element which has a metal carbide stud having a conic tip formed with a reduced diameter hemispherical outer tip end portion of said metal carbide stud. 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.

  • Patent number: 5543792
    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.

  • Patent number: 5541894
    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.

  • Patent number: 5541519
    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.
