Abstract: The display device has an instrument dial (1) of transparent material into which light can be introduced from the side. Underneath the instrument dial (1), a luminous pointer (10), which also consists of transparent material, is arranged rotatably about a pointer axis (15). At a deflection area (12) of the pointer (10), light rays are radiated in the longitudinal direction of the pointer. By designing the pointer (10) to radiate light, the pointer appears to be luminous to an observer. Since the surface (6) of the instrument dial (1) facing the observer is roughened apart from a concentric ring (5), but the ring is polished, the entire area of the instrument dial (1) is weakly luminous whilst the ring remains dark. It is only at the location of the pointer (10) that the latter shines brightly through the ring (5). <IMAGE>

Abstract: A liquid fuel tank for a vehicle is provided with a fuel outlet duct in a circuit about the base of the tank and fuel outlet duct vents connected to the outlet duct and extending above the highest part of the tank. During normal operation of the tank, a non-return air vent allows the flow of fuel from the outlet duct. In the event of an accident, or some other occurrence which results in the tank being tilted, further fuel flow from the outlet duct is cut off by air drawn into the fuel outlet duct from the outlet duct vents. The angle through which the tank must be tilted to allow air from the outlet duct vents to be drawn into the outlet duct may be predetermined by the extent of the circuit about the base of the tank of the outlet duct. Such a non-spill fuel tank, which is self contained in operation, is suitable for use in on-road and off-road wheeled and tracked vehicles, hovercraft, and aircraft which are in danger of being blown over when on the ground.

Abstract: A communications system has a data highway made up of two optical communications channels (28,30) forming a ring to interconnect stations (10,11) whose signals are interfaced with the ring by an optical-electrical repeater (24,25). Each repeater (24,25) includes an optical detector (32) and an optical transmitter (39) for each channel and normally functions as a repeater except when the associated station is transmitting. A control element (31) can prevent the repeater from repeating and a line (33) is provided for receiving the transmitted signal at the transmitting station after it has gone around the ring (28) for checking the condition of the ring. 
     The transfer of mastership is accomplished by grouping into a logical loop of high traffic stations those stations which must be serviced frequently, and the grouping into at least one other logical loop of low traffic stations those requring less frequent service. The token signifying mastership is passed from station to station in the high traffic loop at a maximum speed compatible with the work to be done by each station until a predetermined time period has lapsed since the mastership was passed through the low traffic group. Upon expiration of that time period, mastership is passed sequentially through the low traffic loop stations. Mastership is then returned to a previously determined high traffic loop station. 
     Each local network has two metallic cables (20,22) providing redundant channels between stations (10,11) of a group, the redundant optical rings (28,30) forming the highway interconnecting those networks. The control element (31) connects the output of the detector (32) with the transmitter (39). A control signal supplied over one metallic line (35) from the station which is transmitting causes the control element (31) to disconnect the detector (32) and . transmitter (39) to prevent operation of the combination as a. repeater. The transmission is supplied over another metallic line (38) from the station to the transmitter (39) and thence around the ring until it is converted to an electrical signal at the corresponding detector (32). The resulting electrical signal is then conducted to the transmitting station over still another metallic line (33) for checking as a means for determining if the ring is complete.

Abstract: Es wird ein elektrischer Kondensator vorgeschlagen, welcher vorzugsweise nicht imprägniert und selbstheilend ausgebildet ist und im Wickel zwischen den Dielektrikumsfolien und metallischen Belägen einen gas- oder dampfförmigen Zusatzstoff zum Dielektrikum aus mehratomigen Kohlenwasserstoffverbindungen aufweist. Die Zusatzstoffe, welche als Gas oder Dampf in die Hohlräume des Dielektrikums gelangen, bestehen aus halogenfreien, mehratomigen Kohlenwasserstoffverbindungen, deren Ionisations-potential kleiner ist also dasjenige zumindest eines Teils der Zersetzungsprodukte des Kondensatordielektrikums. Hierdurch wird es möglich, daß im Lichtbogen eines Durchschlages im Kondensatordielektrikum von positiven Ionen der Zersetzungsprodukte die Ladung übernommen wird und Folgedurchschläge weitgehend vermieden werden. Außerdem absorbieren diese Zusatzstoffe bei einem Durchschlag UV-Photonen, wodurch, die Emission von Sekundärelektronen an den Kondensatorbelägen behindert wird. Die Zusatzstoffe sollen weiterhin vorzugsweise frei von Schwefel und/oder von Stickstoff sein, um die Bildung von Säuren und Laugen zu vermeiden, welche sich mit den unvermeidlichen Wasserresten im Kondensatordielektrikum bilden und insbesondere die metallischen Beläge angreifen können.

Abstract: © The measurement circuit for evaluating a digital-to-analog converter (DAC) comprises a clock generator (11) for generating clock pulses, a word generator (3) for generating digital input word for the DAC (1) under clock control, a sampling unit (5, 13, 15) for performing a delayed sampling of the analog DAC output signal under clock control, with a fixed delay time, and a pulse swallower (17) and the word generator (3) for selectably swallowing a number of clock pulses, thus to introduce a permanent time shift between the application of digital input words to the DAC (1) and the sampling of the analog DAC output signal. Thus a digital input word may be selected, by selection of the number of pulses to be swallowed, for application to the DAC (1) for subsequent sampling of the corresponding DAC output signal to occur. This eliminates the need for using a programmable delay line in the sampling unit. The sampling unit (5, 13, 15) may include a fixed delay line (15) and a frequency divider (13). The sampled analog output signal may be digitized by an ADC (7) and processed by a microprocessor (9, 19)
