Abstract: A keyboard for a typwriter and the like, has at least one elongated key, elements for swivellably supporting the key and including at least one substantially U-shaped bracket with a U-bottom, two U-legs connected with opposite ends of the U-bottom, and two projections extending from free ends of the U-legs and parallel to the U-bottom, such that the key is swivellably supported on the projections with a play. At least two stationary swivel bearings swivellably support the U-bottom of the bracket. At least one of the bracket and the key is supported in a bearing point in a noise-dampening manner.

Abstract: In a keyboard for typewriters, printers or the like, where a contact bearing film is disposed underneath the keys, there is provided for achieving a cost-efficient arrangement, while avoiding the use of separate restoring springs, that the contact bearing film (10) has U-shaped cut-outs (11) in the area of the keys (1), the film tongues (12) are bent by 180.degree. and are acted upon by the key tappet (3) of the keys (1), the contacts (14, 15) formed between the base of the film, the underside of the film tongue (12), and the film tongue (12) act at the same time as a restoring spring.

Abstract: A process is disclosed for the preparation of alloy powders, which can be sintered and which are based on titanium, by the calciothermal reduction of the oxides of the metals forming the alloys in the presence of neutral additives. This can be accomplished by mixing TiO.sub.2 with oxides of the other components of the alloy, admixing an alkaline earth oxide or carbonate with the metal oxides, calcining the mixture. After cooling, the mixture is crushed and calcium is added. Thereafter, green compacts are formed which are heated and leached to remove the calcium oxide. The powder obtained is of uniform structure composition, is free of segrations of oxides nitrides carbides and/or hydrides and has high bulk and tap densities and can be molded by isostatic hot molding.
