Abstract: A framework for managing data that provides correlation information in a distributed computing system is provided. The framework includes a generic correlator data structure and service for generating and managing correlators. The generic correlator data structure defines a generic correlator to uniquely identify a specific event occurring at a specific time on a specific thread of a specific process of a specific application executing on a specific machine in the distributed computing system. The correlator may be used to correlate the specific event with another event, even one occurring on a different machine. The generic correlator data structure may be extended, optionally, to include additional context data, for example, specific information selected by a service, tool or other application requiring the correlators. Preferably, the generic correlator data structure is configured to include an association to a partner correlator for a correlated event.

Abstract: A method and apparatus for constructing displays of partially ordered information for event tracing and debugging from systems exhibiting concurrent processing characteristics, such as distributed systems. The method and apparatus provide displays wherein the information is maintained in the partial order while allowing intuitive scrolling of the information on the display through the implementation of predefined unidirectional movement, monotonicity, priority, maximal display and minimal change constraints. The arrangement of the information on the display may be changed by the user and appropriate labels and identifiers can be included as desired. The information may also be grouped into clusters to reduce clutter on the display, allowing information of particular interest to be examined more easily.

Abstract: Pressure-sensitive copying material comprises 3,1 benzoxazine chromogenic material(s) in a solvent comprising vegetable oil and/or a mono-, di or tri-functional ester of a non-aromatic mono-carboxylic acid having a straight or branched hydrocarbon chain with at least three carbon atoms in the chain in addition to the carboxyl carbon atom and an inorganic colour developer. The surface pH of the colour developer is not more than about 8.7, which gives rise to enhanced image intensity and fade resistance compared with the use of 3,1 benzoxazine chromogenic materials in the same solvent with the same colour developer at higher surface pH values.

Abstract: Pressure-sensitive copying material utilizes a blend of rapid- and slow-developing chromogenic materials in vegetable oil solvent and an acid clay or synthetic inorganic color developer. The surface pH of the color developer is not more than 8.7, which gives rise to enhanced image intensity and fade resistance compared with the use of conventional higher color developer surface pH values.

Abstract: A colour developing composition for use in pressure-sensitive (carbonless) copying paper sets comprises an inorganic pigment extender (e.g. kaolin, talc or calcined kaolin) and a hydrated silica/hydrated alumina composite. The composition is produced by precipitating the hydrated silica/hydrated alumina composite in the presence of the extender by the following steps:a) gradually adding a metal silicate solution to a solution of an aluminium salt which is initially at a pH below 4 until the pH of the resulting mixture is approximately 4, thereby to induce some precipitation and to form a sol;b) gradually adding alkali to said sol to raise the pH to approximately 7, thereby to induce further precipitation and gel the sol or further gel the sol, said gelled sol being a hydrated silica/hydrated alumina composite;c) separating the resulting product from the aqueous medium and washing to remove dissolved salts; andd) drying the washed product and reducing it in particle size.

Abstract: A register system such as a carrier management system has a scale for weighing parcels, and a computer for determining shipping costs of the parcels. The computer has a memory including one or more accounting registers. A user PROM having a unique identification number therein is insertable in the system, and an initialization program stores this number in the system memory. Transactions cannot be accounted unless the numbers in the PROM and memory compare. A further PROM is insertable in the system in order to enable the initialization program.

Abstract: A carrier management system includes a scale for weighing parcels to be shipped, a computer connected to receive data from the scale related to the weight of a parcel thereon, and first input keys enabling the input of information. The computer has a data base for storing shipping charge data for a plurality of carriers and/or shipping classes, based upon the weight of a parcel of the scale. The computer is responsive to the operation of the first keys for determining shipping charges for predetermined carriers and/or shipping classes represented by data in the data base. The input includes auto-rate selection key, and the computer is responsive to operation of the auto-rate selection key for determining shipping charges of the least costly carrier and/or shipping class of a predetermined subgroup of carriers and/or shipping classes represented by data in the data base. In one operating mode, the computer may determined the next least costly shipping charges.

Abstract: A carrier management system includes accounting registers, and a program for setting the registers. The program may be responsive to the input of coded values for decoding these values and storing them in the registers. The program may be enabled, for a single operation, by insertion of a service PROM in the system.

Abstract: A carrier management system includes a scale for weighing parcels to be shipped, a computer connected to receive data from the scale related to the weight of a parcel thereon, and a keyboard enabling operator input to the computer. The keyboard has a plurality of keys including a plurality of selection keys corresponding to separate ones or groups of the carriers and/or classes. The computer stores shipping charge data for a plurality of carriers and/or shipping classes, on the basis of weight data from the scale. A second memory receives and stores discount data from the keyboard, corresponding to discounts allocable to any of the carriers and/or classes. The computer is responsive to operation of the selection keys for applying discounts stored in the second means to any carrier and/or class to which they are applicable.

Abstract: Offshore loading system comprising a dynamically positioned vessel and at least two flexible elements, such as hoses extending in different directions from two spaced apart locations according to a preferably double catenary configuration towards a disconnectable coupling provided on an outboard extending arm of the vessel, the arm being swingable inboard and outboard while in the disconnected mode of the coupling. The central position of the coupling is obtained by the catenary configuration of the flexible elements, preferably by giving these elements the form of a double catenary line, obtained by means of a buoyancy device attached to each element and anchored to the sea bottom by a cable or the like.
