4703664 Fluid flow measurement system sensor mounting block
Marine PollutionBulletin being tensioned so that the mooring lines are substantially straight. A counterbalance for the drilling string includes a weighted section located near the bottom of the caisson. A deep draft caisson constructed and arranged so that heave motions are minimal.
4703664 FLUID FLOW MEASUREMENT SYSTEM SENSOR MOUNTING BLOCK Lloyd V Kirkpatrick, John R McGee A system, or apparatus combination, and apparatus components, for the measurement of fluid flow. Such system, or apparatus can be used, e.g. for measuring the amount or flow of drilling fluid, or mud, introduced into a well bore, the amount or flow of mud returned from the well bore, and differences in flow rate and density between the mud introduced into the well bore and the mud returned from the well bore. The system measures or calculates, inter alia, flow rates, viscosity, temperature, density and gas content and compensates for variations; and in marine installations the system additionally measures vessel motion and compensates for wave and tide motions.
4704050 J-CONFIGURED OFFSHORE OIL PRODUCTION RISER Norman R Wallace assigned to Bechtel Power Corporation A riser system having at least one riser with a Jshaped configuration for transporting hydrocarbon fluids from a subsea manifold or wellheads to a surface vessel. The riser has a horizontal section, an upright section, and a sag bend section interconnecting the horizontal and upright sections. The horizontal section is connected at one end to the subsea manifold and extends along and in frictional engagement with the seabed away from the manifold. The upright section has a vertical end part coupled to the surface vessel. The vessel can remain in position with dynamic thrusters or mooring lines, and the vessel remains on station applying horizontal pull to the riser while heading into the prevailing sea and as hydrocarbon fluids are transported from the manifold through the riser to the surface vessel. The horizontal pull on the riser due to the surface vessel is taken up by friction forces between the horizontal section of the riser and the seabed. The riser system can be comprised of a number of risers coupled together in a cluster. In this case, the manifold has a rotatable connector box provided with a number of bores for receiving the lower ends of respective risers. 188
4705642 HAZE, OXIDATION, AND CORROSION RESISTANT DIESEL ENGINE LUBRICANT Rodney L Sung, Benjamin H Zoleski, Ronald L O'Rourke assigned to Texaco Inc A haze, oxidation, and corrosion resistant diesel engine lubricant composition, particularly useful in marine and railway diesel engines, contains 0.1-5.0 weight percent of a reaction product additive. The reaction product additive is produced by first reacting substantially equimolar amounts of an anhydride compound which is either a dibasic acid anhydride or isatoic anhydride and a hydrocarbon-substituted mono primary amine or ether amine at a temperature range of 50 degrees C.- 150 degrees C. to produce an intermediate reaction product. The intermediate reaction product is thereafter further reacted at an elevated temperature with a substantially equimolar amount of a heterocyclic azole or polyalkylene polyamine compound to form the final reaction product.
4707348 METHOD FOR NEUTRALIZING WASTE SULFURIC ACID BY ADDING A SILICATE Roelof D Schuiling, Bilthoven, Netherlands assigned to Rijksuniversiteit Utrecht It has been shown that magnesiumsilicates, particularly Mg-rich olivine, is very advantageous for neutralizing waste sulfuric acid. A silicagel and a Fe/Mg-containing liquid are formed. The experiments show that a distinct separation of the silicagel from the Fe-containing liquid is possible in case the neutralization process is performed in an inert atmosphere. After separation of the SiO2-rich gel a Fe-V precipitate may be formed by means of aeration. The SiO2 gel may be rinsed well, so that an acceptable product is formed that e.g. is useful in the concrete industry. The liquids formed are MgSO4 rich. They may simply be drained into sea-water.
