A centrifugal separator for cleaning of a gas from solid and/or liquid particles suspended therein, includes a stationary housing and a rotor arranged therein. The rotor at its one axial end has a central inlet for gas to be cleaned and delimits a central space communicating with the inlet. Around the central space a stack of conical separation discs is arranged in the rotor. These discs form betw...

According to the invention, the compiled packet filter code is managed in a plurality of pieces, not as a single unit as according to prior art. Preferably, the compiled packet filter code is managed in equally sized pages. When a filter rule is changed, added or removed, only the affected page or pages are changed, added or deleted. This allows for fast updates of the filter code.

Conventional beds have a spring mattress and a sprung base for the comfort o f the user, but on profiting beds, a sprung base cannot be used and, ordinarily, a mattress is laid on lifting and lowering mechanism, with a result that when pivoted or folded, folding or rucking of the surface of the mattress occurs to the discomfort of the user. A first object of the invention is to avoid the above dis...

A cathode layer structure for a solid polymer fuel cell is disclosed. It comprises a composite cathode layer (48) of catalyst (11), anion ion conducting polymer (12) and cation conducting polymer (14). The interface between the anion ion conducting polymer (12) and the cation conducting polymer (14) is located entirely within the cathode layer (48). In particular the catalyst (11) is embedded in s...

A server unit for a multi-user application distributed in a communications network. The server unit comprises at least one storing element for storing application names used only in an application session for an application item during the application session and for storing tag values adapted for application data units for sending application data in the communications network, and mapping elemen...

An exhaust gas channel insert for generating turbulence and/or for mixing gas flowing through said channel (6; 9), said insert (1) partially covering the cross-sectional area of the exhaust gas channel. The invention is characterised in that the insert (1) includes a helical, elongate wire element where each wire turn (2) in the helix includes angled portions such that each turn will have an essen...
