    摘要: In accordance with an exemplary embodiment of the present invention, association forming entities are: a) maintained as objects in a like manner to the data objects being associated; and b) are themselves partitioned objects comprising two or more association fragments, each association fragment being mostly concerned with the interfaces to a particular data object participating in the association. In accordance with an exemplary embodiment of the present invention, each association fragment affiliated with a particular data object is stored in a location that enhances the ease of interaction between the association fragment and the data object. For example, where a first data object and second data object are maintained in data stores at some distance from one another, physically or logically, then a first association fragment will be located with or near to the first data object, and a second association fragment will be located with or near the second data object, at least within the same partition. This arrangement may be preferable because the volume of interaction between a data object and its respective association fragment may far outweigh the interaction needed between the two association fragments. This arrangement may also be preferable as the volume of interaction between a client application and both the data object and respective association fragment may exceed the interaction needed between the two association fragments. Some interactions will employ only one of the association fragments with the net result being a reduction in communications requirements and an improvement in performance. The present invention further provides for defining logical domains which are arbitrary and entirely orthogonal to partitions.

    摘要: A method for selecting a design parameter for a drill bit is disclosed. The method includes entering a value of at least one property of an earth formation to be drilled into a trained neural network. The neural network is trained by selecting data from drilled wellbores. The data comprise values of the formation property for formations through which the drilled wellbores have penetrated. Corresponding to the values of formation property are values of at least one drilling operating parameter, the drill bit design parameter, and values of a rate of penetration and a rate of wear of a drill bit used on each of the formations. Data from the wellbores are entered into the neural network to train it, and the design parameter is then selected based on output of the trained neural network.

    摘要: A removable header for a soft top or similar accessory for a sport utility vehicle. The header has a main body that is releasably securable to the vehicle windshield using just clamps. The header also includes short extensions on each side of the main body that extend rearwardly of it. In use, the extensions abut portions of the safety bar arrangement immediately adjacent the windshield of the vehicle and prevent the header from rotating beyond a predetermined position relative to the windshield.

    摘要: Phosphorus is recovered from the phosphorus sludge formed in the electrothermal production of phosphorus by contacting the sludge with a hydrophobic surface with sufficient force to cause the droplets of phosphorus in the sludge to coalesce and accumulate on the surface, from which it can become detached in the form of large phosphorus drops. One such recovery process involves contacting the sludge, under hydrostatic or other pressure, with a porous membrane formed of a hydrophobic material, through which passes coalesced phosphorus from the sludge, the water and the bulk of the impurities of the sludge being restrained against passage. Other coalescing procedures involve shearing the sludge between sliding hydrophobic surfaces and passing the sludge between hydrophobic surfaces in rolling contact. Typical hydrophobic materials are polyethylene, polypropylene, and rubber.

    摘要: The strength of phosphate shale agglomerates or briquettes is enhanced by adding to and mixing with crushed phosphate shale ore tempering water and a water-soluble alkali metal or ammonium phosphate. The water-soluble phosphate salt is preferably dissolved in the tempering water and the solution sprayed onto the crushed shale ore. The tempering water is added in an amount to bring the moisture content of the mixture between about 9 and 12%. The phosphate salt is added in an amount up to 0.1%. The mixture is compacted into desired size and the compacts calcined.

    摘要: Finely-divided, water dispersible, low molecular weight, linear polyamide resin particles having a unique morphology and of uniform particle sizes are formed by preparing a linear polyamide of a predetermined low molecular weight in the presence of water followed by rapidly quenching the reaction mass with an aqueous medium below the freezing point of the polyamide and continuing the cooling of the mass to a temperature sufficiently low so as to prevent particle growth and structural alteration while regulating the pH of the quenched mass to provide particles of predetermined, uniform size dispersed in the aqueous medium. The particles vary from ultimate flaky sheets or lamellae to loosely packed, randomly oriented, clusters of flaky sheets. Spray dried products may be agglomerates which disintegrate readily in water to the original particles or aggregates depending upon intended uses. The dispersions and dried products are useful in the coating art and the polyamide may be polymerized to high molecular weights after application to a substrate.
