A method and apparatus for providing back-up management of a network element in a multi-tiered network management system. Network elements have a primary element manager responsible for managing communications with that network element and a secondary element manager that can be at a geographically remote location responsible for assuming control of communications with the network element should t...

The conveying apparatus has a transport belt (10) which is intended to feed flexible, flat articles (12) arising in imbricated formation (S), resting freely, to a conveyor (14). The transport belt (10) is led around a deflection drum (16) and, together with the latter, forms a deflection and conveying gap (26) for the imbricated formation (S). On one side, an edge section (21) of said imbricated f...

Process for the preparation of hydrogen and/or carbon monoxide rich gas by catalytic steam reforming of a hydrocarbon feedstock, wherein a first stream of the feedstock is autothermally steam reformed in parallel with a second stream of the feedstock being steam reformed in presense of a steam reforming catalyst in heat conducting relationship with hot effluent from the autothermal steam reforming...

An externally powered propulsion device particularity designed to propel floating and submerged water craft, as well as any other vehicles (land or air). The device utilizes a helical coil drive mechanism which causes a flexible body plate(s) to move and undulate in such a way that a travelling unilineal wave motion is produced. The resulting wave creates thrust within any fluidic medium. (See att...

The building is divided into two main sections, one being a section (1) for organic compost material, and the other being a section (3) for refuse sorted into different fractions.

An ultrasound reflector (29) is secured to the treatment catheter (12) at a given distance from the heat source (10, 11) in order to localise heat in the gland (19). A catheter is inserted into the urinary tract and connected to a heat source in order to warm up the tissue adjacent to this source, the power for the heat being supplied from an external unit.
