Abstract: A drive system (30) for a closure device at the casting nozzle of a metallurgical vessel (10) has a piston/cylinder unit (40) which is attached to the said vessel, controls the closure device via a linkage and has a valve lock which is made up of a control valve (55) and of a by-pass valve (55) used for the manual operation of the closure device. According to the invention, the piston/cylinder unit (40) is designed as a synchronised-motion cylinder, the cylinder of which has a part (46) that forms the working chamber (49) for the piston (45) sliding therein and a part (48) which is connected to the abovementioned part and contains the valve block. Part (48) and the piston rod (42') arranged therein are provided with a travel sensor (60) while the piston rod (42) opposite the piston (45) is coupled to the linkage for the movement of the closure member (20). These two parts (46, 48) of the cylinder are furthermore manufactured from aluminium. This and the fact that the said lines and hence the valve lock are fully integrated into the said parts (46, 48) give the considerable advantage over the known solutions that this piston/cylinder unit (40) is very light overall and, furthermore, very compact and, as a result, very small in size. <IMAGE>

Abstract: In the alternate routing in a communication network (NI) for switched connections, the path sections for setting up a connection are tested step by step for their seizability from exchange (Vst A,... Vst E, Vst G, Vst H) to exchange (Vst B,... Vst F, Vst G, Vst H). Blocking (BL1) of a path section and lacking or failed overflow mandatorily cause the desired connection to be released to the originating exchange (Vst A). According to the invention, the alternate routing can be used again step by step in rear transit exchanges (Vst C) involved in the setting up of the connection when the blocked connection is released in the reverse direction. <IMAGE>

Abstract: The ball valve coupling includes first and second ball valve units having interengageable lugs for releasably connecting the ball valve units in face-to-face relation. The first ball valve unit includes a ball valve movable between open and closed positions. A safety lock-out key is mounted on the first ball valve unit for movement from a first position toward a second position in response to partial engagement of the lugs on the first and second ball valve units. A stem pin is mounted on the first ball valve unit for movement with the ball valve between the open and closed positions. The safety lock-out key is moved from the first position and when the ball valve is in the closed position to prevent movement of the ball valve to the open position. The stem pin engages the lock-out key when the lock-out key is in the first position and when the ball valve is in the open position to prevent movement of the lock-out key from the first position.

Abstract: Applicants have discovered that glass optical waveguides subject to hydrogen-induced loss increases can be passivated by treating the glass with deuterium. The deuterium-treated glass not only exhibits a lower rate of loss increase when later exposed to environments containing H₂, but also retains high transmission of light in the 1.55 and 1.31 micrometer wavelength regions immediately after the deuterium heat treatment. The method applies to Er-doped fiber, transmission fiber and planar waveguides. Under some circumstances, hydrogen can be substituted for deuterium.
