The method for fabricating a composite rattan piece having an effective diameter sufficient to form a rigid structure. Relatively smaller diameter rattan segments are steam heated until deformable. These segments are then helically wound to define a larger diameter piece. The piece is cooled and shaped into the desired configuration to define a rigid support which can be used to assemble furniture...

Method of collecting information as to the actual starting and finishing points of journeys taken with public transport, irrespective of changes in route and/or conveyance, at least the points of time and boarding at the start of the journey being registered on a fare document. In conjunction with boarding the conveyance it is examined whether predetermined transfer conditions for a previous journ...
