A multichannel decentralized radiocommunications system is known in which each station, before establishing a radio link to a neighboring station, scans all channels and creates a so-called channel occupancy list. The neighboring station can be used as a relay station by establishing a radio link to a further station in a corresponding manner ("radio chain"). Each station must thus have a scanning...

Device to grip and manipulate bobbins of textile thread, used to grip, move and transport cops (10) after the textile thread has been wound on, the cops (10) having an inner cavity (10c) and flanges (10b) at the ends, the device being suitable to cooperate with at least one end of the cop (10), the end of the cop (10) including toothed clamping means (18) protruding therefrom and facing outwards, ...

A method for defining a color gradient across a region in a display space that includes defining a bi-cubic patch enclosing the region. The bi-cubic patch includes four corners having a color associated therewith and four curves connecting pairs of the corners forming a closed loop. The four curves define the color gradient across the bi-cubic patch as a function of the four colors associated with...

A capsule holder for retaining a mixing capsule on a rotary mixing device includes a carrier plate 10, an actuator disk 11 rotatable relative to the plate, and two retaining arms 12, 13 for clamping the capsule from opposite sides, the retaining arms having driving pins 22 engaging spiral cam slots 26 of the actuator disk 11. By rotating the actuator disk 11, the retaining arms 12, 13 are moved aw...

The present invention describes an improved electrode suitable for application in solid polymer electrolyte fuel cells, comprising a thin, porous, planar, conductive substrate having one side coated with a pre-layer consisting of conductive carbon having a low surface area mixed to a first hydrophobic agent, to which is applied a catalytic layer consisting of platinum supported on conductive carbo...
