Abstract: A welding head for a welding device is operable to weld a component which is not rotationally symmetrical onto a workpiece. A head attachment includes a holding device for holding the component and to carry a welding current to the component. A mouthpiece is arranged around the holding device and the component during a welding operation. The holding device and the mouthpiece move in relation to each other along a welding axis. The mouthpiece contacts the workpiece and provides a protective gas tangentially about the welding component. An interface device supplies the welding current to the holding device. A connecting device mechanically connects the holding device to the interface device. The connecting device is subdivided into a first connection piece connected to the holding device and a second connection piece electrically insulated from the first connection piece.

Abstract: The invention relates to a welding head for a welding device for welding components which are not rotationally symmetrical onto workpieces such as for example metal sheets, with a head attachment, the head attachment having a holding device for the component and being designed for carrying a welding current to the component, wherein the holding device is mechanically connected by means of a connecting device to an interface device, via which the welding current can be supplied, the connecting device being subdivided into a first connection piece and a second connection piece, which are electrically insulated from each other.

Abstract: The invention includes an apparatus and associated methods for facilitating communication between a managed system and management systems. The apparatus includes at least one protocol agent and a management layer. A protocol agent is adapted for communicating with at least one management system using a protocol. The protocol agent includes at least one protocol entity. The management layer is adapted for facilitating communication between the at least one protocol entity and system hardware including a plurality of physical system entities. The management layer includes a plurality of logical system entities associated with the physical system entities. The management layer supports at least one mapping between the logical system entities of the management layer and the protocol entities of the protocol agent. The apparatus facilitates downstream communications from one or more management systems to the managed system, and upstream communications from the managed system to one or more management systems.

Abstract: The invention includes method and apparatus for generating a protocol agent adapted to facilitate communications between a managed system and at least one management system. The method includes generating an implementation of a unified information model from an information model specification and generating the protocol agent from a protocol specification. The protocol specification includes first mappings to the information model specification and the protocol agent includes second mappings to the implementation of the unified information model. The second mappings are formed using the first mappings. The information model specification includes a model of hardware of the managed system. The implementation of the unified information model includes a plurality of logical entities, wherein the logical entities represent a plurality of physical entities of the managed system. The protocol specification includes a model of a protocol. The protocol agent includes a plurality of protocol entities.

Abstract: The invention relates to a formulation having a plurality of phases containing active ingredients. Said formulation is characterised in that: it contains a first, innermost, finely distributed phase (I) consisting of active ingredients or an active ingredient solution, preferably some of the phase particles being surrounded by a barrier sheath (M); the formulation has a second, intermediate phase (II) that serves as a dispersant for the first, inner phase (I) and can also be dissolved in the active ingredient; and the formulation has a third, outer phase (III) that serves as a dispersant for the second intermediate phase and can, in turn, be dissolved in the active ingredient and/or can be in the form of solid particles that can, in turn, be surrounded by a barrier sheath. In this way, a plurality of biological active ingredients can be produced in the different phases in different concentrations and with a respectively controlled release rate in a single formulation.

Abstract: There is provided a system for connecting signals between at least two electronic modules. The interconnection conduits are provided via one or more blades, which are equipped with connection areas along their edge toward the modules. This structure opens up more room for high frequency signaling connections. The blades used for the interconnect can be replaced in a live system during operational conditions.

Abstract: The process for producing crystallisation products with an average particle diameter of <1 .mu.m is based on the atomisation of a solution and the simultaneous evaporation of the solvent. The atomised solution A crystallises in a gas atmosphere, in which it is simultaneously contacted with a cloud of drops 4 of a surfactant-containing liquid B, thus forming an aerosol mixture A, B which is then deposited in the form of a colloidal crystal suspension in which the surfactant-containing liquid B forms the continuous phase. The cloud of drops 4 of the surfactant-containing liquid can also be produced by atomisation.

Abstract: A computer having a plurality of plug-in modules is provided with a holding circuit for transmitting an interrupt signal over an interrupt signal line. The holding circuit conducts the interrupt signal in the appropriate manner regardless of whether or not a given module is plugged in. At the same time it ensures that a plugged-in module responds to the interrupt signal in the appropriate manner.
