    摘要: The invention relates to a legrest for a wheelchair, provided with a footrest and a calfrest. In a first, supporting position (ready for use), this footrest and calfrest are designed for supporting at least a part of a leg of a user seated during use in the wheelchair. The calfrest can be moved to a non-supporting, second position (ready for transfer), wherein the calfrest is located outside the space which is occupied by the legs of a wheelchair user upon sitting down in and/or rising from the wheelchair. The pivotal direction of the calfrest is then such that the path of travel between said first and second position is located substantially outside the space occupied by the legs of the wheelchair user in the first, supporting position.

    摘要: An improved method for producing tantalum (V) nitride by means of nitriding an oxidic tantalum (V) compound is described. The Ta.sub.3 N.sub.5 product obtained in accordance with this method may be used as a red coloring pigment, particularly for coloring plastics and varnishes. An improved color intensity can be achieved and/or the reaction time can be shortened using the process in accordance with the invention. The process includes nitriding tantalum (V) hydrated oxide with the composition of the formula Ta.sub.2 O.sub.5 .multidot.aq with a hydrate content (i.e., aq content) in a range of 14 to 17% by weight. The nitridation preferably takes place in the presence of a fluxing agent such as ammonium carbonate or boric acid.
