This invention relates to the partitioning of a communications network. The idea of the invention is to divide the logical connections of a communication network into several partitions, each partition representing a certain type of transmission traffic, such as access or regional traffic. The partitioning is based on simple criteria: capacity of an endpoint of a logical connection, representing a node; distance between a pair of endpoints, and traffic category representing the stability of the ...

A tensioning apparatus for a lashing strap (8) includes a frame (1) having side walls (5, 5'). One end of the lashing strap (8) is fixed to the frame. A spindle (11) is rotatably secured to the frame (1), bridging the space between the side walls (5, 5') and bearing a tensioning lever (17) for winding the lashing strap (8) up from its free end. Ratchet devices that are employed at either end of the spindle (11) permit the operator to select whether a push or a pull on the tensioning lever (17) i...

Method of flux-free contacting of components on a substrate, having the following process steps: producing elevated contact metal bumps of a flux-treated gold-tin solder material on tags of the component; removing flux residues on the surface of the component; melting the elevated contact metal bumps and contacting the contact metal bumps with tags of the substrate.

The present invention relates to a low-vulnerability solid-propellant motor (1) comprising a charge (11) of solid propellant, a heat shield (2) covering the inside of a metal structure with a front end wall (3) and a rear end wall (4) which carries at least one nozzle (10), the said front and rear end walls being fastened to a cylindrical shell (5) having wide apertures which are circumferentially distributed and temporarily sealed by sealing plugs (8). The object of the present invention is to ...

Improved techniques for reporting events raised by entities running on computer networks are disclosed. The techniques provide an event distribution system that handles events generated by various software and other entities installed on a computer or communications network. The event distribution system is capable of handling large volumes of event traffic and can be installed and operated separately from other network management software components to provide thereby more robust operations in ...

A software facility for automatically identifying subnetworks in a network is described. The facility receives a plurality of addresses of hosts in the network, and accesses a binary tree. The nodes of the binary tree each represent a range of addresses within the network. A facility traverses the binary tree to identify candidate nodes where both child nodes have one or more descendent leaf nodes representing host addresses. The facility tests the address range represented by each candidate nod...

An apparel folding device suitable for folding apparel in a quick and consistent manner is disclosed.

A bottom panel hingedly connected to the first panel may also be provided between the two side panels. The bottom panel and two side panels may each include a lipped handle. In addition, each of the two side panels may be constructed from two sub-panels. This permits the device to be shipped in a ...

A system and hydraulic jack are disclosed for stressing concrete structures with stranded steel cable. In one embodiment, a pocket is formed in a concrete slab with two pairs of stranded cables extending in opposite directions in the slab. Each pair of cables defines a plane that is perpendicular to the plane formed by the other cable pair. One pair of cables is passed in a first direction through apertures in a splice block and secured to it with conical grips. The other pair of cables is passe...
