Title: Separable plug connection for a tubular plug-in part with a circular support rib
Inventor: MORETTI ERMINIO
IPC: F16L37/133
Filed: 1993-12-07
Abstract: A releasable plug-in connector for receiving a tubular plug-in part having a peripheral retaining rib. The plug-in connector consists of a housing having a cylindrical receiving space for receiving the plug-in part, and a separate securing ring made from a hard/resilient plastic material. The ring has retaining edges directed inwardly in the form of an arc of a circle that are pushed apart as the plug-in part is pushed into the connector and that then spring back elastically and engage behind the retaining rib after the plug-in part has been pushed in to lock the part in the connector. The retaining edges are connected to one another at their ends by a pair of V-shaped spring webs that are accessible from the outside of the housing so that they can be pushed into an unlocked position permitting the part to be pulled out of the connector.

Abstract: A method of detecting a drillstring washout during an operation involving the addition or removal of pipes from the drillstring such as back reaming, comprising: a) performing at least one such operation and determining by hydraulic coefficient k from the relationship            P = kQ       a              ,where Q is the flow rate, P is the standpipe pressure and a is the flow exponent, from each pipe added or removed, so as to derive a series of values indicating the development of k for said operations, and b) on subsequent operations, determining k and comparing the determined values with the series obtained previously, a drillstring washout being detected when the determined value of k falls substantially below the corresponding value of k in the series. The trend in the development of k can be calculated and used to determine if an anomaly exists in the determined value of k.

Abstract: A high frequency voltage generator ( 10 ) produces a high positive voltage and a high negative voltage. A parallel connected coil ( 26 ) and diode ( 30 ) are connected between the high voltage supply and a target ( 44 ) of an x-ray tube ( 40 ). A second parallel connected coil ( 28 ) and diode ( 32 ) are connected between the negative voltage and an electron source ( 42 ) of the x-ray tube. The coils are preferably a multiple pancake design (FIGURE 3). When the tube starts to arc, the sudden increase in current flow through the coil is converted and stored in a magnetic field leaving only a small current to contribute to arcing. The coils are sized such that the current which passes to the x-ray tube is sufficiently small that the arcing is usually extinguished without an avalanche phenomenon occurring. The diodes permit the energy stored in the magnetic field to be converted into a current flow through the coil and diode such that the energy is dissipated as heat by the inherent electrical resistance of the coil with only a minimal amount of the energy passing over time to the x-ray tube.

Abstract: L'invention se rapporte à des modifications de la somatotrophine qui ont entraîné des améliorations inattendues dans sa stabilité structurelle et chimique sans perte de bioactivité. Les changements de ces caractéristiques ont été obtenus par la modification des somatotrophines par mutogenèse dirigée sur le site. Ces changements augmentent la stabilité de conservation de ces protéines. Les modifications typiques sont celles des somatotrophines du porc comportant des substitutions de glutamine et d'histidine arginine aux positions 19 et 20, respectivement (Q19H, H20R); l'acide glutamique est substitué à la phénylalamine à la position 52 (F52E), et l'acide glutamique est substitué à la leucine à la position 137 (I137E).
