Abstract: A bearing arrangement comprises: first and second thrust bearings, each including an inner race which is disposed on a shaft and an outer race which is supported by at least one resilient element. Applying a shaft thrust load elastically deforms the resilient elements so as to axially displace the respective outer races in order that the thrust load is shared between the first and second thrust bearings.

Abstract: This invention concerns a system for cooling components in a gas turbine engine, the gas turbine engine including a compressor for driving a primary gas flow to a combustor and a turbine arranged to be driven by combustion gases from the combustor, wherein the system includes: an annular cooling flow passage arranged for fluid communication between the compressor and the turbine, the flow passage having a first inlet arranged to receive gas from the primary gas flow downstream of compressor, and a second inlet located upstream of the first inlet, wherein the annular cooling flow passage has at least one internal wall for guiding airflow from the first inlet towards the airflow from the second inlet, the airflow from the first and second inlets coalesce within the annular flow passage prior to passing along the passage in a direction from the compressor to the turbine.

Abstract: A bearing arrangement is disclosed. The bearing arrangement includes first and second bearings, with each bearing including a respective support element and a respective set of rolling elements and defining a respective load path extending through the respective support element and rolling elements. The support elements are coupled such that a load applied to either support element is transmitted through both the first and second load paths. The arrangement further includes a pair of superelastic titanium alloy elements located in the respective load paths to provide resilient movement between the bearings when a load is applied to the bearing arrangement.

Abstract: A gas turbine engine comprising at least one drum pack having two or more annular discs 62a-c. Adjacent discs 62a-c are connected by drive arms 68 the drum pack is provided with a tubular sealing body 84 positioned radially inwards of the drive arms 68 and extending from a first disc 62a to a last disc 62c in the drum pack. The first 62a and last 62c discs have the greatest axial separation of all discs 62a-c in the drum pack. The sealing body 84 engaging the first 62a and last 62c discs and the engagement being arranged to limit or prevent the ingress of liquid into a drum cavity 76 defined between the first 62a and last 62c discs, the drive arms 68 and the sealing body 84.

Abstract: Methods and apparatus provide for an event identity manager that defines a topology of resources. The topology of resources represents relationships amongst the resources in a data center and each of the resources comprises resource attributes described in a data model. The event manager acquires event data describing an event that occurred amongst the resources. In addition, the event data comprises a format that is incompatible with the data model. The event manager correlates the event data with the data model in order to determine a locus of the event data within the topology of resources, the locus of the event data being a resource where the event is most likely associated.

Abstract: A gas turbine engine having three shafts connecting respective high, intermediate and low-pressure turbines and compressors is characterised by an intermediate pressure turbine that includes two rotor stages.

Abstract: The invention relates to compounds of formula I and to pharmaceutically acceptable salts, prodrugs, solvates or hydrates thereof; wherein B, D, E, R1, R2, R3, R4, R5, R8, m, n, p, q, r, s, t and u are as defined herein.

Abstract: A method, apparatus, and article of manufacture for providing round-trip resolution to customer error reports (CERs). This improves on CERs in supporting quality assurance for software systems by providing appropriate responses to the customers. The result is a novel technique for improving software quality and customer satisfaction.

Abstract: A method, apparatus and article of manufacture for prioritizing customer error reports for a software application. A sub-bucketing algorithm is performed in a computer to sort stack traces associated with the customer error reports by a plurality of lines or entries in the stack traces, in order to create a hierarchy for categorization of the customer error reports.

Abstract: The invention relates to NEP inhibitors for treating cardiovascular disorders. Preferred NEP inhibitors are compounds of formula (I) wherein R1 is C1-C6alkyl, C1-C6alkoxyC1-C3alkyl or C1-C6alkoxyC1-C6alkoxyC1-C3alkyl; R2 is hydrogen or C1-C6alkyl; L is a three atom linkage selected from —CH2—X—CH2— and —CH2—CH2—X— where the right hand side of the linkage is attached to R3 and where X is oxygen, sulfur or methylene; R3 is phenyl or aromatic heterocyclyl, either of which may be independently substituted by one or more groups selected from: C1-C6alkyl, halo, haloC1-C6alkyl, C1-C6alkoxy, haloC1-C6alkoxy, C1-C6alkylthio, haloC1-C6alkylthio and nitrile; and R4 and R5 are either both hydrogen, or one of R4 and R5 is hydrogen and the other is a biolabile ester-forming group that in the body of a patient is replaced by hydrogen.

Abstract: This Object-Oriented programming system migrates persistent objects when their class declarations are modified. The objects and their class descriptions are persistently stored and the persistent versions of an objects' superclass descriptions are compared to later versions of the objects' superclass descriptions. When a persistent version and a later version of the class description for the object differ, the object is migrated from the persistent version to the later version based on the differences between the two superclass descriptions. Finally, the migrated object is persistently stored with changes in its persistent class description.

Abstract: This system involves an object persistence framework for an object-oriented program which provides a persistent class, data storage class and a data cursor class, that permits specialized implementations of object storage and retrieval with heterogeneous permanent storage systems.

Abstract: Software modules which are not part of a database systems source code is provided for interactively maintaining the semantics of concept hierarchies when concept properties and concept interrelationships are modified. These separate modules include command and rules modules. Each of the commands in the command module are linked to the appropriate rules in the rules module. The rules module is bifurcated into a check section and an action section. If the command does not violate any applicable rule in the rules section, the action section implements the command. If the command violates one or more applicable rules, the action section suggests alternate action. If no suitable action can be found, the action section implements reverse commands to return the database to its unaltered state.

Abstract: This invention uses a rule based system which is configurable at run time(1) to decide whether suitable preconditions exist for proposed modifications to a data base, (2) if not, optionally attempt to bring about such preconditions, and (3) prevent the proposed modifications if preconditions remain unmet.

Abstract: The present invention is an catalog database system and method in which there are a plurality of catalog objects. Each catalog object contains at least one attribute and at least some of the catalog objects have at least one search path leading to at least one other object. A first object and the attributes of other objects in the electronic catalog are displayed. Those attributes which are defined in the first object and inherited to all descendant objects which are in any search path leading from the first object are displayed as strongly relevant attributes. Those attributes which are defined in at least one object which is in any search path leading from the first object are displayed as weakly relevant attributes. Those attributes which are contained in no objects which are in any search path leading from the first object are displayed as irrelevant attributes. To access a catalog object, a selection of an attribute or attribute value from among those displayed is accepted from a user.
