Patent EP-0417936-A2 (EP)
Inventor: COX PERCY TERRELL
IPC: E21B47/10
Filed: 1990-08-29
Abstract: Fluid from an oil well being tested is allowed to accumulate in a settling tank and, after a predetermined settling time, is pumped through a flowmeter (25) and a water-cut meter (30). The water-cut meter first determines the impedance of the free water pumped from the tank and later determines the impedance of the oil/water emulsion flowing from the tank. The ratio of the emulsion impedance to the free water impedance is proportional to percent water-cut of the fluid during the water-continuous phase. When the flowing emulsion becomes an oil-continuous phase, the system utilizes probe impedance for the water-cut determination. The water-cut and flow rate signals are combined to calculate the total oil and water content of the settling tank fluid. The magnitude of the phase difference between high frequency current and voltage probe signals is used to determine the point at which the flowing emulsion becomes an oil-continuous phase.

Abstract: A bus arbitration method is disclosed for multiple processors (20,21) that can be incorporated into an arbitration scheme that is designed to include only a single processor. The method includes consolidating the individual bus requests of each processor into a single bus request supplied to the single processor arbitration scheme (75). When control of the bus (54) is allocated to the single processor, the multiprocesor arbitration (134) arbitrates among the processors who requested the bus. The bus protocol used includes a least recently used method for granting bus access to the multiple processors coupled with a means (PCL1,PCL2) for giving one processor priority over the others for access to the bus. The protocol also includes protection from interruption for the respective processor in control of the bus for a preset period of time.

Abstract: Melt-blended filled thermoplastic resin compositions include a thermoplastic matrix resin, a filler material and a thermoplastic additive resin. The compositions of the invention include discreet continuous phases of matrix resin (A) and additive resin (C), with the filler material (B) being present substantially entirely within the the additive resin phase (i.e. substantially absent from the matrix resin phase). The components A, B and C are selected so that their respective surface tensions allow the additive resin to form a complex three-dimensional network structure within the matrix resin when melt-blended, and such that substantially all of the filler material is homogeneously dispersed throughout the three-dimensional network structure.

Abstract: A thin film metal alloy magnetic recording disk has an improved protective overcoat which is both wear resistant and which creates a low level of stiction in a rigid disk file. In a preferred embodiment the overcoat is a film of essenti­ally amorphous carbon or hydrogen-containing carbon with relatively small amounts of additives of iron (Fe), tungsten (W) or tungsten-carbide (WC). The structure of the overcoat is a relatively smooth planar carbon surface with discrete clusters of the additives which project slightly above the smooth carbon surface. The specific additives to the carbon overcoat improve the wear resistance of the disk and permit the sliders to contact the disks in contact start/stop (CSS) operation without damage to any of the disk file components.

Abstract: This invention relates to a method of manufacturing bi-metallic tubing by the successive steps of explosive bonding, hot extrusion and co-extrusion. Bi-metallic tubing, having an inner wall made from a corrosion resistant material, is of particular use in the oil and gas industries. The invention offers a number of advantages over previously known manufacturing methods, such as increased cladding capacity, reduction in the number of joints required, and an improvement in dimensional accuracy. These are achieved by explosively bonding a tube (3) of a first metal to a substantially incompressible billet (1) of a second metal. A length of the bonded composite (15) so formed is subsequently hot extruded to form a bi-metal shell (25). A length of the shell (25) is then placed within the bore of a hollow billet (33), the interface (35) formed between the shell (25) and billet (25) sealed, and the assembled composite (39) so formed co-extruded to form a bi-metal tube (41).

Abstract: A RIM molding technique includes a mold having a mold plate which is permitted to move in response to the injection of a liquid resin material, thereby permitting injection at a low injection pressure. The technique is applied to applying a molded resin coating film on the surface of a resin molding such as, for example, a fender of an automobile. In one embodiment, the molding is formed by blending resin component A with resin component B immediately prior to injection into the mold cavity. The coating film is similarly blended, and injected as the mold plates are permitted to move apart to accommodate the added material. In another embodiment, the molding is formed by compression molding of a resin composition sheet. The coating film is injected over the resulting molding while the mold plates are permitted to move apart. A resin handling system circulates resin component A and resin component B in isolated paths until it is time for blending the components and injecting them into the mold cavity. At that time, the blender (25) blocks the outlets, and directs the two components to a blending area. The blending area communicates with an injection nozzle (26) for injecting the resulting blend into the mold cavity. Material A generally contains an active hydrogen component (polyamine) and material B generally contains an isocyanate component.
