Abstract: The wall (29) of the friction-spinning means (28) has bores (30) of a diameter L and, on its side facing a fibre feed channel, a coating (34) which extends over and beyond the edges (31) into the bores (30). A hole (37) is thereby formed at the mouth (32) and has a diameter J smaller than the bored diameter L and an area of less than 0.283 mm<2>, but at least 0.07 mm<2>. This as far as possible prevents fibres or fibre particles from penetrating into the hole (37) when air flows through the holes (37) in the direction of the arrow (M), whilst at the same time preserving a hole shape advantageous in terms of flow and clogging.

Abstract: In a system comprising a collection of signal processing apparatuses (1, 2, 3, 4) and a switching device (5), each apparatus is connected, by means of a universal con­nector (6, 7, 8, 9) which is identical for each apparatus, to an arbitrary connection of the said switching device. The signal path between two or more connected apparatuses is established in that a first apparatus supplies a report command for the switching device in at least one further apparatus, after which the switching device finds out to which connector a further apparatus is connected in that said further apparatus in reaction to the report command has supplies an identification signal as a result of which the switching signal recognises the connector to which said further apparatus is connected. Once it has been found out to which connec­tor the first and the further apparatuses have been connected, the switching signal establishes a signal path herebetween.

Abstract: Une boîte de changement de vitesses à plusieurs étages avec marche arrière se caractérise par une longueur hors tout très courte. Elle comprend un arbre moteur (11) et un arbre mené (12) agencés coaxialement, deux arbres secondaires (13, 14) parallèles aux premiers et des jeux d'engrenages agencés sur ces arbres, les engrenages se situant sur trois plans. Les manchons de couplage des divers engrenages avec leurs arbres se situent sur un même plan, qui à son tour se situe entre les plans des engrenages. Cet agencement a pour résultat une construction extraordinairement compacte de la boîte de changement de vitesses, surtout pour ce qui est de sa longueur axiale, de sorte que cette boîte de changement de vitesses s'associe particulièrement bien avec une boîte de changement de vitesses agencée coaxialement en aval de la première; sa construction sous forme d'un système d'engrenages planétaires permet de maintenir la longueur totale dans les limites de celle des boîtes de changement de vitesses simples de l'état antérieur de l'art.

Abstract: Recently, processes have been described for producing gypsum fibre boards, in which the boards are formed from a paste containing calcium sulphate dihydrate and fibres. By heating and subsequent cooling of the boards, the dihydrate is first converted into hemihydrate and then recrystallised again to give dihydrate. In the prior processes, setting times of several days resulted, which are unsuitable for large-scale industrial utilisation of these processes. According to the invention, water is drawn through the boards after cooling. Preferably, setting accelerators are dissolved in the water. These measures shorten the setting time to less than two hours. The strength of the boards (7) can be increased by adding a binder, for example starch. …<IMAGE>…
