Abstract: The present invention relates to novel ethane derivatives of the formula 1 <IMAGE>  in which R<a> is straight-chain alkyl having 1 to 8 carbon atoms, <IMAGE> or (m = 1 or 2; n = 0 or 1) and R<b> is straight-chain alkyl having 1 to 8 carbon atoms in which, in addition, one or two non-adjacent and in each case non-terminal CH2 group(s) may be replaced by -O-, and to the preparation of the compounds of the formula 1, to liquid-crystalline phases containing compounds of the formula 1, and to their use as components of liquid-crystalline phases. The compounds of the formula 1 have high chemical stability and only low conductivity. They are colourless and readily miscible with all common liquid crystals. Their use in liquid-crystalline phases results in broader mesophase ranges and reduced viscosity. The compounds of the formula 1 according to the invention are thus highly suitable for liquid-crystalline phases for electrooptical display devices, such as, for example, TN cells or guest-host cells.

Title: Method of manufacturing a vehicle body consisting of a synthetic resin, vehicle body manufactured with this method and vehicle provided with such a vehicle body
IPC: B62D29/04
Filed: 1989-03-18
Granted: 1992-05-20
Abstract: A method for manufacturing a synthetic vehicle body 1 is presented. The body 1 is laminated integrally with a bottom part 2 and with synthetic longitudinal girders 3 to form a self-supporting and flexible deformable unit. Because of the flexibility of the laminated self-supporting body 1, the body is able to take up torsion forces by deformation of the body. Such forces arise for example when driving in a car with a loaded vehicle body. By flexible deformation of the body 1 high point loads at supporting points of the body 1 with the chassis of a car are avoided. Preferably U-shaped girders 3 are reinforced by extra laminating in particular the curved parts of the girders 3. A body 1 with such girders 3 is laminated into a stable closed structure.

Abstract: Monitoring equipment is provided in a charging rectifier for operational monitoring of a converter supplied by the AC voltage supply network and is provided with DC voltage feed via two rectifiers serving the purpose of decoupling, in particular, via one of the two rectifiers from an auxiliary converter likewise supplied from the AC voltage supply network, on the one hand, and via another of the two rectifiers from a DC converter supplied by the DC energy storage device, on the other hand. The DC voltage offered by the DC converter is higher than the DC voltage offered by the auxiliary converter. The monitoring equipment distinguishes between these DC voltages with reference to magnitude and, when receiving a lower DC voltage, checks for the presence of the DC voltage supplied to the DC converter by the DC energy storage device. When receiving the lower DC voltage and given the presence of the DC voltage supplied to the DC converter, the monitoring equipment outputs a signal that indicates a malfunction of the DC converter.
