Abstract: Multi-node data processing apparatus is described, in which the nodes (10) are interconnected by multiple transmission links (11). Before a node can transmit a message, it must acquire a unique transmission sequence number (TSN) which it appends to the message when transmitted. Each node receives messages from all the links, and organises them into strict TSN order before processing. This ensures that all the nodes process all the messages in the same sequence. The TSN may be acquired, for example, from a special ring (12) interconnecting all the nodes.

Abstract: An optical switch array comprises a plurality of optical switches of the kind utilising the interaction between light propagating along one of two waveguide path sections in close proximity to one another and an electrical field produced by electric switching voltages applied between electrodes actively associated with the waveguide path sections in order to effect switching of the light from one of the waveguide path sections to the other. The waveguide path sections which provide links between the optical switches of the array and which require electrical isolation from one another have dissimilar physical or other characteristics in order to prevent coupling therebetween in the presence of a nearby electric field.

Abstract: Es wird eine Zweikomponentenmasse auf Basis von härtbaren Präpolymeren sowie üblichen Zusätzen beschrieben, die im Unterschied zu herkömmlichen Zweikomponentenmassen in beiden Einzelkomponenten härtbares Präpolymer enthält, wobei das Präpolymer in der ersten Komponente ein Polyurethanpräpolymer mit freien NCO-Gruppen ist und das Präpolymer in der zweiten Komponente ein Polymer mit freien SH-Gruppen ist. Die 1. Komponente enthält Härter und gegebenenfalls Beschleuniger für das Polymer mit freien SH-Gruppen, und die 2. Komponente enthält Härter und gegebenenfalls Beschleuniger für das Polyurethanpräpolymer mit freien NCO-Gruppen. Durch die Verwendung von zwei Präpolymeren können die beiden Komponenten der Zweikomponentenmasse in einem für praktische Zwecke günstigen Volumenverhältnis verwendet werden. Außerdem können Viskosität und Dichte der beiden Einzelkomponenten auf etwa gleiche Werte eingestellt werden, so daß die Vermischung der beiden Komponenten unproblematisch ist. Die beschriebenen Zweikomponentenmassen härten sehr schnell aus und sind gegenüber Dosier- und Mischfehlern wenig empfindlich. Darüber hinaus liefern die beschriebenen Zweikomponentenmassen im ausgehärteten Zustand bei gegebener Elastizität hohe Festigkeiten. Die beschriebenen Zweikomponentenmassen eignen sich insbesondere als Dichtstoff, Klebstoff, Beschichtungsmassen und Gießmassen.

Abstract: A method and apparatus for the conversion of stationary magnetic energy into mechanical energy, under the application of two or more, in their relation to one another, movably positioned bodies. Said bodies consist wholy or in part of permanent magnetic or magnetizable material. With at least one of the bodies a stationary magnetic field is created, under the influence of which, on at least one other of the bodies in magnetized condition, locally a force of magnetic origin is exerted, of which the vectorial resultant makes an angle unequal to zero degrees with the normal to the polar plane at said location of said other body. As a result, said bodies mutually move in substance along each others polar planes. Said stationary magnetic field may be generated by permanent magnet means or electromagnet means, excited by a constant electric current. Preferably superconducting electromagnet means are used.

Abstract: The invention relates to a process for the production of elastomer skins as coating material for plastic mouldings, for instance motor vehicle fascias, in which a preliminary mould taken from a working model has introduced into it first of all a release agent and then a polyurethane system, which forms an elastomer skin suitable for handling and stable in storage, which upon completion of the reaction is demoulded and finished in a final mould to produce a moulding. The invention is based on the object of further developing this so-called in-mould coating in such a way that UV-resistant elastomer skins can also be produced with undercuts and narrow, deep depressions without any problems and absolutely accurately in their dimensions. According to the invention, this is achieved by a polyurethane lacquer being provided between release agent and polyurethane system, the preliminary mould being moved, before the layers are introduced, by turning at least to some extent into a position in which its side facing the injection mould has a substantially convex curvature, and by the demoulded elastomer skin being turned back again before its finishing in the final mould.
