Abstract: A circuit arrangement for a control device implements a fail-silent and/or fail-safe function, particularly with a hardware-realized detection of a fault or a faulty state in a microcontroller of the circuit arrangement. The circuit arrangement interrupts the communication of the control device with a communications network when a fault is detected.

Abstract: The invention relates to a circuit arrangement for a control device (SG). The circuit arrangement serves to implement a fail-silent function/a fail-safe function, particularly with a hardware-realized detection of a fault/fault state in a microcontroller (MC) of the circuit arrangement, as well as to interrupt the communication of the control device (SG) with a communications network (BN) in the event of a fault.

Abstract: Polyesterols having reduced reactivity are prepared by catalytic polycondensation of dicarboxylic acids/dicarboxylic acid derivatives and H-functional substances using tin catalysts by a process wherein the polyesterols are brought into contact with oxygen after the end of the esterification reaction. The polyesterols themselves obtained by this process are used for the preparation of PU.

Abstract: A RF antenna system mounted on, for example, a dielectric carrier plate is accommodated as a homing head in the front under a radome in a missile provided for locating radar systems or the like, in addition to other, further sensors potentially present in free spaces. The RF antenna system is composed of a three's or four's group of logarithmic-periodic crossed dipole antennas whose long axes proceed with optimized dimension obliquely relative to one another and that are interconnected with a monopulse feed network for taking aggregate and difference diagrams in azimuth and elevation. The antenna system for long-range missiles enables a monopulse position fixing in azimuthal or, respectively, elevational direction in an extremely broad frequency range.

Abstract: This invention relates to radio-derivatized polymers and a method of producing them by contacting non-polymerizable conjugands with radiolysable polymers in the presence of irradiation. The resulting radio-derivatized polymers can be further linked with ligands of organic or inorganic nature to immobilize such ligands.

Abstract: A drop coating compound in particular, for unhoused electrical and electronic circuits and components. The compound includes highly filled ultraviolet-curable epoxy resin compounds having improved properties with respect to their use and in comparison to previously used, predominantly two-component, thermally curable resins.
