摘要:
The invention includes a method and apparatus for managing a system specification. The method includes identifying a first system specification defined at a first refinement level where the first system specification includes specification data, generating a second system specification at a second refinement level where the second system specification inherits the specification data of the first system specification, modifying the inherited specification data of the second system specification, and storing the second system specification including the modified specification data.

A reconfigurable hardware architecture, in the form of a System-on-Chip 1, includes an ASIC (19) and an embedded FPGA (18) which define static and reconfigurable parts of an IC architecture (15) respectively. Incoming Ethernet, or other format, packets are applied to a packet filter (14), which detects those packets containing reconfiguration data. The reconfiguration data is used to update the FPGA (18).

The invention relates to a contact arrangement (1) for a relay for switching high load currents. Furthermore, the invention relates to a relay (43) for switching high load currents having a contact arrangement (1). Finally, the invention relates to a method for assembling a relay. In order to be able to assemble the contact arrangement (1) in the relay in an at least partially automated manner, without additional retention devices being required for a cord (4), there is provision according to the invention for the cord (4) to be retained in an inherently stable manner owing to its shape as a self-supporting structure and for the method to have a method step in which the cord (4) is shaped to form a self-supporting structure with a bent shape.

For connecting flexible corrugated hoses, which are not provided with fittings, for transporting preferably gaseous media in connection with high-pressure applications, a holder 3 is provided, which receives an exposed end of the corrugated pipe 6 of the flexible corrugated hose 2 and is pressed together with it to form a metallic seal. The metallic seal is achieved by the surface pressure between the interior wall 18 of an element 16 of the holder and the ribs 8 of the corrugated pipe 6. Elastomeric seals 24, 25, as well as a soldering joint 34, if desired, can be provided as aids. However, in connection with a preferred embodiment the required sealing is already achieved by the strong pressure against each other of the metallic exterior of the corrugated pipe 6 and the metallic interior of the element 16. A further element 17 of the holder 3 fixes a section 28 of the sheathing 11 of the flexible corrugated hose 2 in the axial direction, as well as in respect to tilting movements, so that pivot movements of the flexible corrugated hose 2 do not lead to a relative movement between the corrugated pipe 6 and the holder 3, in particular the element 16. Thus, the sealed area remains unaffected, even in case of mechanical tensile or bending stresses of the flexible corrugated hose assembly 1.

The invention relates to an electromagnetic relay with an electromagnetic coil for exciting a magnetic field and an iron circuit for guiding the magnetic field, wherein the electromagnetic coil surrounds at least part of the iron circuit and the iron circuit comprises a core, a movable armature and a yoke. The electromagnetic relay further comprises a contact system with a movable contact bridge which can be actuated dependent on the magnetic field. In order to provide an electromagnetic relay that is able to disconnect or connect a plurality of electric contacts simultaneously in a particularly secure and loss reduced manner, according to the present invention there are provided at least three electric contacts on the contact bridge. According to an advantageous embodiment, the contact system comprises three fixed contacts which are corresponding each to one of three phases and the contact bridge forms a star point of the three phases.

The invention includes a method and apparatus supporting system specification creation by providing descriptor management functions. A method according to one embodiment of the invention includes receiving a request for descriptor information maintained in a descriptor dictionary comprising a plurality of descriptor entries defining a respective plurality of descriptors, determining a context associated with the request for descriptor information, retrieving a subset of the descriptor entries of the descriptor dictionary according to the determined context, and inserting into a presentation data stream imagery associated with the subset of descriptor entries to enable selection of one or more of the descriptor entries for insertion of the corresponding descriptor within a worksheet.

A widening device for increasing the width of a moving web of material comprises a rotatable profiled roller, the outer surface of which defines a plurality of radial projections and recesses distributed along the length of the roller and first and second co-operating rollers rotatable at the same speed as the profiled roller. The first and second co-operating rollers define projections and recesses complementary to those of profiled roller and define first and second treatment nips which serve to increase the width of a web of material passed therethrough. The projections on the co-operating roller defining the second treatment nip extend more deeply into the recesses of the profiled roller than do the projections on the co-operating roller which defines the first treatment nip so that the web of material is stretched gradually over two stages with the stretching effect being uniform across the entire width of the web.
