The present invention relates to a mobile communication system comprising a mobile services switching center and a visitor location register and a home location register, the information on particular subscriber stations being stored therein, and comprising means for transmitting a cancellation message to said visitor location register for removing the subscriber information on a particular subscr...

Disclosed are absorbent cores for inclusion in articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent core is designed so as to retain low levels of fluid in the crotch region, relative to the other core regi...

At least one active part such as an airbag for the head or knees, and at least one passive part such as a deformable, energy-absorbent cushion are incorporated into a replaceable modular unit.

The invention relates to an arrangement for establishing a leaktight connection for a thin-walled plastic vessel for connection of a hose or a pipe or members performing functions or carrying out measurements. The arrangement can be mounted in its entirety from the outside of the vessel. The arrangement comprises on the one hand a first surface (10; 110; 210; 310) designed in such a manner that, d...

Filters for filtering molten light metals comprise a reticular foam having a composition comprising graphite, wollastonite, silica and an alkali phosphate glass. The filters have a low hardness and can readily be machined accurately from large pieces of the filter material. In a preferred embodiment the exterior surfaces of the large pieces of filter are coated with a composition comprising graphi...

Improved solar cell circuit layouts and cell structures that protect solar arrays located on spacecraft disposed in geosynchronous earth orbit from electrostatic discharge. An insulating material, such as RTV adhesive, for example, is used as a barrier that disposed in intercell gaps between solar cells. The use of the insulating material modifies sparking in the gaps caused by electrostatic disch...
