Patent EP-0242633-A1 (EP)
Inventor: SPOTORNO LORENZO DR-MED
IPC: A61F2/34
Filed: 1987-03-27
Abstract: The external bowl of the hip joint endoprosthesis is provided with a plurality of circumferential rows of projections. In addition, each projection is provided with a flank in a plane perpendicular to the axis of symmetry of the bowl and a second flank which faces the equatorial plane of the bowl which defines an angle of from 15 DEG to 45 DEG  with the other flank. Upon penetration into bone tissue, the flanks displace and condense the tissue to approximately the same extent so that the axial force components acting on the flanks are approximately equal. This reduces the tendency of the endoprosthesis to be expelled from the bone.

IPC: H05K7/20
Filed: 1987-10-14
Abstract: 2.1 Cooling by convection or by fans is necessary to dissipate the heat losses from drawers, containing assemblies of electrical apparatuses, which are pushed one above the other into cabinets. Space is required between the drawers for this purpose, and this takes up useful space in the cabinet. The new drawer housing is intended to reduce the space requirement for ventilation and to render the known fan drawers and heat sinks superfluous. In standardised systems in the past, at least two height units were required for each ventilation measure. 
<??>2.2 In the new drawer housing, its jacket 2 is only one height unit HE higher than the assembly carrier 1. Within the jacket 2, underneath the assembly carrier 1, there is an air inlet shaft 9 and an air outlet shaft 10 above it, the air inlet shaft 9 being connected to a front air inlet 15, provided in a front frame 17, and the air outlet shaft 10 being connected to an air outlet opening 16 in the rear wall 8 of the housing. 
<??>2.3 The drawer housing, which is just as suitable as a table housing as for pushing in, is used within the context of the 19 inch construction system.

Abstract: The invention uses direct position measurement. A measuring signal generated by a measuring head 2 upon reaching the desired position of a part 1 of the machine tool is converted by a digital control 7, which is a component part of a position regulation 5, into a reversal signal, changing the direction of rotation of the drive motor 10. The normal position regulation is interrupted by the reversal signal and at the same time a predetermined reset value 57 is generated in a correction control circuit 20, is superimposed as reset signal 59 on the position regulation and turns the drive motor 10 back by an angle corresponding to the backlash on reversal. <IMAGE>

Filed: 1987-07-08
Abstract: An optical duplex system may continue to operate after a break in a fibre if light is reflected at the break and received back at the transmitting station, and that station is unable to identify the origin of the data. To prevent this, in a simple 2-channel duplex system, data transmitted from one end is inverted prior to transmission and reinverted at the receiving end, while information from the other end is transmitted and received without inversion. If there is a break, the stations at both ends will receive inverted data and the fault is quickly revealed. In a 2x4 channel multiplex system, one channel from one end is inverted before transmission, whilst three channels from the opposite end are inverted before transmission.

Abstract: Bei symmetrischer Zeilenablenkung kann infolge von Hysterese der Elektronenstrahl von Zeile zu Zeile verschoben werden, so daß keine Synchronität mit dem Bildinhalt vorliegt. Zur Beseitigung dieses Fehlers wird angestrebt, die Abweichungen des Elektronenstrahls an den Bildrändern sicher zu erkennen. Erfindungsgemäß wird wenigstens ein vertikaler, vorzugsweise an einer der Seiten der lichtemittierenden Schicht angeordneter Indexstreifen angeordnet. Ferner sind Sensoren vorgesehen, die mit einer Auswerteschaltung zur Auswertung des Zeitpunktes, in dem der Elektronenstrahl den Indexstreifen passiert, verbunden. Eine Komperatorschaltung zum Vergleich der Indexsignale mit den Zeilenablenksignalen bewirkt über eine Steuerschaltung eine Verschiebung des Bildinhaltes von aufeinanderfolgend geschriebenen Zeilen. Die Erfindung ist besonders für Fernsehempfänger mit großer Bildröhre und energiesparender Zeilenablenkschaltung geeignet.
