IPC: H02M7/515
Filed: 1991-07-18
Granted: 2000-06-20
Abstract: With respect to their connection to snubber capacitors (C1, C2), a discharge resistor (12) connecting these snubber capacitors, and a link capacitor bank (3), inverter circuits with GTO thyristors (T1, T2) connected in series have parasitic leakage inductances which limit the level of the permissible link direct voltage. In order to reduce the leakage inductances, the snubber capacitors (C1, C2). are surrounded by effectively conducting capacitor covers (17). Sheet-metal shielding covers are fitted over the two ends of the discharge resistor (12).      Parallel and series connected capacitors of the link capacitor bank (3) are connected to the positive/negative terminals (23, 24) of the GTO thyristors (T1, T2) in the middle of a heat sink connecting strainer (33), the supply leads being guided essentially parallel and the capacitors being arranged in opposite planes.

Title: Manufacture of an air bag fabric
Inventor: KRUMMHEUER WOLF RUEDIGER
IPC: B60R21/16
Filed: 1991-09-06
Granted: 1999-07-27
Abstract: Manufacture of an air bag fabric having zones of differing air permeability which are variable in shape and size.  A dobby, tappet or Jacquard machine is used to weave into a fabric having a tight basic weave window-like zones with a weave which differs from the basic weave, as a result of which these zones have a high air permeability.  The  zones  of  low air permeability  are arranged in such a way that later they form the edges of cuts and seams. It is further possible to manufacture fabrics which have zones of differing air permeability by alternating sections of high warp or weft sett with sections of low warp or weft sett. The fabrics of the invention are suitable in particular for the filter part of air bags.

Title: Night vision backlighting system for liquid crystal displays
Inventor: FARRELL JAMES F
IPC: G02F1/1335
Filed: 1992-07-16
Granted: 1999-06-15
Abstract: This invention presents a way to provide night vision viewing compatibility of backlit electrooptic modulated light valve or LCD displays designed for daylight viewing.  Liquid crystal displays (LCD) designed with backlighting systems which provide a high brightness, good contrast display under daylight conditions are inappropriate for use in dark, night time conditions where viewing of the display is desired utilizing electronic night vision equipment.  This invention describes improvements to standard backlighting displays which through the utilization of arrays of low-level intensity light sources such as secondary fluorescent light sources, miniature incandescent lamps or light emitting diodes, the general means used in daylight vision can be turned off and the secondary low-level lighting sources achieve a minimum intensity acceptable for night vision electronic viewing.

Title: Process for preparing a polymer using lithium initiator prepared by in situ preparation
Inventor: OZAWA YOICHI
IPC: C08F36/04
Filed: 1993-10-18
Granted: 2000-10-17
Abstract: A process for preparing a polymer comprises polymerizing a conjugated dime monomer and/or a vinylaromatic hydrocarbon monomer in a hydrocarbon solvent in the presence of or in the absence of a randomizer by using a lithium polymerization initiator which is formed by bringing an organolithium compound and at least one secondary amine compound into contact with each other in the polymerization system in the presence of at least said monomer. The secondary amine is an amine compound having two hydrocarbon groups bonded to N or an imine compound in which an NH group and a saturated or unsaturated cyclic structure group form a cyclic structure.      The cyclic structure group comprises a hydrocarbon group as the ring member and may also comprise N or O. The method of production uses the initiator which does not require separate preparation of the initiator, shows excellent reproducibility, allows for the evaluation of accuracy of concentration and realizes high effective initiator concentration. The high molecular weight polymer produced by the method has a narrow molecular weight distribution; is controllable; has a highly reproducible molecular weight and microstructure; exhibits excellent coupling properties based on the living polymerization and provides low hysteresis loss properties.
