Abstract: A process and apparatus for the plasma deposition of a carbon-rich coating onto a substrate is provided. This method includes the steps of: providing a substrate in a vacuum chamber; and generating a carbon-rich plasma in the vacuum chamber by injecting a plasma gas into a hollow cathode slot system containing a cathode made of two electrode plates arranged parallel to each other, providing a sufficient voltage to create and maintain a carbon-rich plasma in the hollow cathode slot system, and maintaining a vacuum in the vacuum chamber sufficient for maintaining the plasma. The plasma is deposited on the substrate to form a carbon-rich coating.

Abstract: Rail vehicles have a brake linkage being acted on by a brake cylinder for acting on at least one wheel set of a bogie, truck or running gear of the rail vehicle through brake blocks having brake block shoes and brake block shoe inserts. A block brake for rail vehicles should be economical and be constructed in such a way that higher braking capacities can be achieved, that damage to the tires of the wheels of the wheel set is avoided and that wheel noise of the wheel sets is minimized. The block brake includes at least one rotationally symmetrical brake body being fixedly disposed on a wheel set shaft of the wheel set between the wheel discs of the wheel set. The acted-on brake block rests on an outer surface of the brake body.

Abstract: A device for mounting and fixing the hydraulic unit of an anti-lock system as a carrier for the hydraulic unit includes a bracket which is itself fastenable to the vehicle body. The hydraulic unit is mounted in a vibration-insulating manner by three rubber bearings on the bracket arranged fixedly on the body. These bearings each comprise a bearing journal connected firmly to the housing of the hydraulic unit. A thick-walled rubber sleeve buffer surrounds the bearing journal coaxially. A half-shell-shaped bearing element is fixed to the bracket and supports the respective rubber buffer over a lower 180.degree. region. The half-shell-shaped bearing elements and the shell parts are equipped with catch elements which can be brought into positive engagement with one another.

Abstract: A voice control circuit controls the volume range of the voice signals in a communication terminal, such as a video telephone having a hands-free facility. In a hands-free facility, the signal-to-noise ratio is lower than in telephones with handset. To avoid audible feedback, hands-free facility conventionally includes a volume control circuit which decreases or increases the gain in the receive path as the gain in the set path increases or decreases. The problem to be solved is to utilize the maximum possible loop gain without reducing the gain in the receive path. The idea is to place behind the microphone (50) a controllable compandor (52) in which the signal voltages from the microphone (50) are A. compressed if they lie above a predetermined level, B. expanded if they lie below the predetermined level, and C. imparted maximum gain if they have the predetermined level.

Abstract: Chemical complexes, useful as radiopharmaceuticals, are formed by reacting technetium-99m with substituted or unsubstituted alkyl monophosphonic acids and certain ester derivatives thereof. The complexes are formed by reducing pertechnetate ion chemically or electrolytically in the presence of the phosphonic acid. By chemical modification of the phosphonic acid complexing agent, it is possible to "tailor" complexes for kidney, liver or bone imaging. The complexes are normally used in a physiologically acceptable aqueous medium.
