Abstract: Joints métal/métal pour joints tubulaires de type à extrémités mâles et femelles (70, 80) où les surfaces annulaires d'accouplement (75, 85) sont usinées à des angles légèrement différents si bien que la charge du contact initial repose entièrement sur le bord d'attaque de la surface annulaire de l'élément mâle et le bord arrière de la surface annulaire de l'élément femelle. La variation de la surface de scellage est choisie pour toute géométrie spécifique de joints de telle façon que, au blocage final, la distribution de la charge s'effectue d'une manière relativement régulière sur toute la surface de scellage en contact, distribuant ainsi largement les pressions de contact de blocage et minimisant toute tendance au grippage qui pourrait en résulter, en particulier pour des joints dotés de parois relativement minces pour des organes à extrémités mâles et des organes à extrémités femelles.

Abstract: A receiver for radio broadcasts is proposed which has an analysis circuit for digitally transmitted traffic information. The radio receiver has a memory with road-oriented segments which are subdivided into route segments. For reception of digital traffic information it is sufficient to specify the road, the route segment, and the direction. On the basis of the arrangement in the memory, it is then possible for the receiver to generate the other information itself. This means that the digital data transmission can take place at a high repetition rate. <IMAGE>

Title: Measuring device
IPC: G01B5/00
Filed: 1987-12-28
Granted: 1990-12-05
Abstract: As shown in Figure 1, in this length measuring device (1) a rigid material measure (2) is connected by means of two angularly mobile couplings (11, 12), which are stiff in the longitudinal direction of the material measure (2), to the two fastening elements (9, 10), which fix the material measure (2) on one of the machine components (5) to be measured. As a result, changes due to heat in the length of the machine component (5) are transferred to the material measure (2) with the correct sign. Because of the angular mobility of the couplings (11, 12) harmful transverse forces cannot act on the material measure (2). <IMAGE>
