  • Patent number: 11578439
    Abstract: A method of manufacturing a wet-laid nonwoven web includes the following steps: feeding a pulp suspension onto a forming screen for depositing a fibrous web thereon, wherein the pulp suspension has industrially produced, inorganic fibers or fibers of synthetically produced polymers and the pulp suspension is substantially free from binders, such as chemical binders, and hydraulic consolidation of the fibrous web to generate the nonwoven web through water jet needling of the fibrous web.
    Type: Grant

  • Patent number: 11118309
    Abstract: A device dewaters a wet-laid non-woven web formed from a fibrous suspension. The device has a multiplicity of dewatering strips which are disposed so as to be mutually spaced apart. Mutually neighboring dewatering strips conjointly delimit a dewatering gap for discharging liquid from the fibrous suspensions. The device further has at least three format slides which along the longitudinal direction of the respective dewatering gap are disposed or disposable so as to be distributed relative to one another and which partially obscure the dewatering gap in such a manner that any discharging of the liquid by way of the obscured part of the dewatering gap is prevented.

  • Patent number: 9792563
    Abstract: Defining a human resource system is disclosed. Metadata models are defined. Processes are defined. The human resources system is stored including metadata models and processes, wherein the stored metadata models and processes are interpreted using an interpretive engine, wherein the interpretive engine is configured to process the metadata model and process definitions without compilation of any code, and wherein defining metadata models and defining processes when interpreted by the interpretive engine is sufficient to define a fully functional human resource system.

  • Patent number: 7970779
    Abstract: An application programming interface configured to transform data responsive to a transform process definition. The transform process definition is interpreted concurrently with the transformation process. This interpretation dynamically determines navigation within, and processing of, the data to be transformed. Under control of the transform process definition, a transform engine is configured to transform input data using recursive calls to a transformation process. The recursive approach is responsive to data structures within the transform process definition and simplifies operations such as parallel processing, load-balancing of transformation tasks, nesting, un-nesting, filtering, and the like.

  • Patent number: 7831982
    Abstract: Various techniques for processing service operations and for developing a service interface in a service oriented data architecture are provided. When processing a service request, a first service implementation is executed in a first operation mode. The first service implementation calls at least one second service implementation, which is executed in a second operation mode. When developing a service interface, at least one aggregated service object and at least one aggregated service operation are defined, the aggregated service operation using the aggregated service object such that the aggregation structure of the aggregated service operation matches the aggregation structure of the aggregated service object.
