Patent EP-0474914-A1 (EP)
Inventor: SAILER HEINRICH DIPL-ING
IPC: H04B10/54
Filed: 1990-09-14
Abstract: In a bi-directional optical waveguide telecommunications system with telecommunications devices which in each case have a laser module, the monitor diode of which is also used as a receiving diode, the telecommunications devices work in grouped-frequency operation entailing a modulation circuit which precedes the laser transmitting diode converting the electrical transmission signal into a frequency band other than that occupied by the electrical reception signal; a frequency filter following the monitor diode then leads on the one hand to a reception-signal demodulation circuit and on the other hand to the operating-point control circuit of the laser transmitting diode.

Abstract: Un dispositif de déviation d'un faisceau de rayons sur un angle prédéterminable O comprend un prisme déviateur rotatif autour de l'axe d'un faisceau incident de rayons (7), dont la surface (4) d'impact des rayons est approximativement perpendiculaire à l'axe de rotation. Le dispositif de déviation comprend en outre un système de reproduction associé au prisme déviateur. Le prisme triangulaire permet d'obtenir des basculements de l'axe de rotation, dans la direction du faisceau dévié, inférieurs d'un facteur 10 environ aux basculements obtenus avec un miroir ou un demi-cube. L'utilisation du prisme triangulaire représente une simplification considérable par rapport à l'utilisation d'un prisme quadrangulaire selon Wollaston ou d'un prisme pentagonal dans un dispositif du même type, étant donné qu'il présente uniquement trois faces optiquement planes au lieu de quatre, une seule étant pourvue d'une couche réfléchissante (6) au lieu des deux des autres types de prismes. On peut ainsi obtenir des économies de matériau supérieures à 50 %, avec des tolérances de fabrication moins contraignantes.

Abstract: PCT No. PCT/DE90/00632 Sec. 371 Date May 27, 1992 Sec. 102(e) Date May 27, 1992 PCT Filed Aug. 14, 1990 PCT Pub. No. WO91/05356 PCT Pub. Date Apr. 18, 1991.In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft. This drive shaft passes through the housing of the grounding switch. To design the contact elements that transfer the ground potential to the movable switching piece as simply as possible, the drive shaft consists of electrically conductive material. In addition, the drive shaft is insulated as it enters the housing. The drive shaft is also coupled with means to transfer the ground potential, e.g., a current strip, outside the housing. Thus, the drive shaft serves both to transfer force and to transfer potential. A switch blade is designed to be elastically deformable in part, and serves as the movable switching piece. This grounding switch for an encased, compressed-gas-insulated high-voltage switching system can also be used as an insulated grounding switch to carry out measurements.

Abstract: The present invention is directed toward methods for the production of non-infectious, replication-deficient, immunogenic human immunodeficiency virus (HIV)-like particles. These particles are prepared from a recombinant expression vector comprising a heterologous promoter operatively connected to a DNA molecule comprising a modified HIV genome devoid of the long terminal repeat (LTR) regulatory regions but containing at least the gag and pol genes in their natural genomic arrangement. This vector is introduced into mammalian cells to produce the particles of interest. These particles should prove useful in a number of diagnostic, virologic, and immunologic applications.
