Inventor: KOWALSKI BERND DIPL ING
IPC: H04L9/32
Filed: 1993-07-16
Abstract: 2.1 In securing data traffic in known systems of this type, discrepancies occur between optimum protection against unauthorised intervention, even of an internal nature, on the one hand and hindrances to use, e.g. storage problems and the protection of personal data, on the other hand. 2.2 In the method according to the invention, a mutually exclusive division of the scopes of authorisation is carried out, in which one type a) relates to the operating system and to the guaranteeing of availability and reliability, and a second type b) serves to prevent and identify unauthorised intervention and to collect associated operator data. For this purpose, two separate databases with different methods of access are formed and a session number is set up as an aid to data integration. 2.3 The invention is suitable for all types of security management systems in distributed and complex data transmission, telecommunications and data processing systems, even for commercial payment transactions.

Title: Process for preparing acicular cobalt-containing magnetic iron oxides
Inventor: SCHWAB EKKEHARD DR
IPC: G11B5/84
Filed: 1994-08-12
Abstract: The invention relates to a process for preparing high-coercitivity acicular (needle-shaped) cobalt-containing magnetic iron oxides having a core-shell structure and low temperature dependence of the coercive force resulting therefrom, wherein, in a first step, a surface activation is carried out on the iron oxide core under an inert gas atmosphere by means of iron(II) and cobalt ions under alkaline conditions, before, in a second step, an epitactic coating containing cobalt ferrite is subsequently applied, which coating is oxidatively formed from iron(II) and cobalt(II) hydroxide under likewise alkaline reaction conditions. The total amount of the cobalt ions used for the doping remains unchanged in comparison with the known doped iron oxides or is even lower. In the second process step, the achievable coercive force can be controlled by the proportion of air in the gas mixture during the formation of the epitactic coating.
Patent DE-4430262-A1 (DE)
Inventor: WEISENBERGER HELMUTH DIPL ING
IPC: F16F15/129
Filed: 1994-08-26
Abstract: A torsional vibration damper for a clutch plate of a motor vehicle comprises two side discs 17 rigidly connected together but spaced apart and a central disc 27 arranged axially therebetween. Helical compression springs 29 are arranged in windows 31, 33 in the central disc 27 and the side discs 17 to couple the side discs to the central disc in an angularly resilient manner. A stop element 35 passes through a window 31 in the disc 27 radially inwardly of one of the springs 29. The stop element 35 limits the maximum relative angle of rotation between the central disc 27 and the side discs 17 to a value which prevents the turns of the springs 29 from becoming "solid". The stop element 35 does not take up space in a circumferential direction at the expense of the springs 29. It can also connect ring elements of a friction device to the side discs 17. <IMAGE>

Filed: 1994-09-01
Abstract: An oscillation circuit with a high frequency accuracy is disclosed which is capable of performing a stable frequency oscillation even when a PLL is in a standby state and is suitable for use in communication equipment of a TDMA method using one PLL. The oscillation circuit includes a PLL frequency synthesizer circuit (1). Input to a flip-flop (9) are a power save signal PS from a CPU for controlling the entire transmitter-receiver and a lock detection pulse LOCKDET from a PLL IC (1). When the power save signal PS and the lock detection pulse LOCKDET are input at the same time, the flip-flop outputs the power-save signal after the lock detection pulse LOCKDET ceases. As a result, the oscillation circuit is controlled to be placed in a standby state without making the operation of a VCO unstable. <IMAGE>
