Patent EP-0741727-A1 (EP)
Inventor: KEPLINGER DIETMAR
IPC: C07D491/22
Filed: 1995-01-31
Abstract: To produce defined isomer mixtures of compounds with spiro β-aminocarboxyl and/or β-aminocarbonyl systems the invention proposes that they be dissolved in solvents which have good dissolving power for these compounds, whose relative permittivity is sufficient to stabilize the amphoteric intermediates occuring in isomerization, which as proton donors constitute hydrogen bridges, whose basicity is less than that of the compounds for isomerization and whose boiling point is so high that an adequate reaction speed can be attained by raising temperature. Further, the invention proposes that the isomerization be influenced or terminated by altering at least one of these factors and/or by altering the temperature.

Abstract: In a secure communication system 100, communication units in different communication groups may be simultaneously rekeyed over the air by having a managing key unit 101 generate a key packet 121. This key packet 121, which includes a unit key 122, a key alias 123, and a key representation 125, is transported to at least one fleet key unit 102. Upon receiving the key packet 121, the fleet key unit determines, based on the key alias, which communication units of which communication groups are to be rekeyed. Once this is determined, the key representation 125, which represents the unit key (encryption key) 122, is transmitted to the communication units, thus rekeying multiple communication units in multiple communication groups simultaneously.

Patent EP-0734432-A1 (EP)
Title: Synthetic ester lubricant stabilizer composition
Inventor: LAI JOHN T
IPC: C10N60/04
Filed: 1994-12-15
Abstract: An antioxidant composition suitable for ester fluid lubricants is the reaction product of diphenylamine and N-aryl naphthylamine in the presence of an organic peroxide. The mole ratio of diphenylamine:N-aryl naphthylamine is about 1:1 to about 10:1. This results in more oligomeric reaction products and significantly less unreacted monomeric residual reactants. The resultant product composition comprises DPA homo-oligomers and DPA-NPA cross oligomers. The diphenylamine and N-aryl naphthylamine are desirably substituted with alkyl groups having from 1 to 20 carbon atoms or styryl groups. The reaction temperature is preferably about 130° to about 150° C. Controlled reaction conditions allow the use of solvents with extractable hydrogen atoms without producing significant amounts of dehydrocondensation between the solvent and the diamines. The reaction products have superior oxidative resistance in the Oxidation Corrosion Stability Test (OCS) and Vapor Phase Coker Test over dehydrocondensation products produced under other conditions and are useful in lubricant composition, especially in synthetic ester fluid lubricants such as turbine engine oils.

Title: Circuit for processing signals from a yaw-rate sensor
Inventor: LOHRENZ FRANK
IPC: B60T8/00
Filed: 1995-03-08
Abstract: The circuit described for processing the signals from a yaw-rate sensor (11) is intended particularly for controlling the stability of a motor vehicle (1). The circuit has a control unit (18) to which are fed the signals from the yaw-rate sensor (11) as well as those from other sensors (4, 5, 6, 7, 10, 12 and 13) which measure travel-condition-dependent parameters such as wheel rpm, steering-wheel angle, lateral acceleration and longitudinal acceleration. The control unit (18) computes from the inputs from one or more of these other sensors a reference yaw rate and compares it with the rate measured by the yaw-rate sensor (11). In addition, the plausibility of the yaw-rate sensor signal is checked, taking into consideration the vehicle travel condition. If the difference between the two yaw rates is greater than a given threshold value, the signal from the yaw-rate sensor (11) is rejected as faulty on the basis of the plausibility check.

Filed: 1995-06-14
Abstract: A video signal processing apparatus contains a teletext processor (107) with a non-volatile memory (115) for storing characters to be displayed on a screen, said characters being recorded with a redundancy-reducing code. A control device (111) ensures that the data are decoded when they are read and are retransmitted to a device (113) that generates screen driving signals. Since the characters are compressed before being stored, the teletext processor (107) may be produced as an integrated circuit even when extensive sets of characters need to be processed.

Abstract: The invention relates to a process for regulating a four-quadrant regulator (1), the output side of which powers three-phase drives via a d.c. intermediate circuit (5) and pulse rectifier (6) and the input side of which is connected to an a.c. system (4), preferably via a multi-winding transformer (2) with secondary windings (8, 9) for the four-quadrant regulator (1) and additional consumers, e.g. auxiliary converters (10) and an interference filter set (3), especially for use in catenary-powered three-phase locomotives. In order to provide a process by means of which the often considerable additional reactive power generated on the mains side by the auxiliary converters (10), especially with the traction converter on partial load, can be compensated simply and cheaply, the invention  proposes that in addition to the effective power regulation, the reactive current to be fed into the a.c. mains (4) by the four-quadrant regulator (1) be constantly regulated, where, besides the sum of the currents in the drive or four-quadrant regulator (1), the currents in the interference filter set (3) and possibly those of the auxiliary operating converter (10) are detected and used for reactive current control.
