Abstract: An amplifier (60) provides an amplified video signal in response to a video input signal supplied thereto. A cathode current sensor (Q3), couples an output of the amplifier to the cathode of a kinescope (20) and also provides an output current (Ik) proportional to the kinescope cathode current. A feedback path (82) applies a portion of the sensed cathode current provided by the cathode current sensor to a circuit node (65 or 63) in the amplifier for imparting gamma correction to images produced by the kinescope. In one application the cathode current is apportioned (Q3, Q5) to provide gamma correction for the kinescope and to provide automatic kinescope bias (AKB) control.

Abstract: A metallurgical vessel has a refractory head piece and a vessel outlet at the refractory head piece. A sliding gate valve for this metallurgical vessel includes a housing frame that is mounted to the vessel at the outlet so as to be removable therefrom. A slider unit is mounted in the housing frame having a sliding plate therein. A refractory base plate is also mounted in the housing frame, and has an upper side with a plane sliding surface that is engaged with the refractory head piece and a lower side having a lower sliding surface that is parallel to the plane sliding surface. The sliding plate is pressed against the lower sliding surface of the refractory base plate. The refractory base plate is fixed in the housing frame in a direction parallel to the sliding surfaces of the refractory base plate, but is movable in the housing frame in a direction perpendicular to the sliding surface of the refractory base plate.

Abstract: A discharge assembly for controlling the discharge of molten metal from a vessel includes a stator member mounted to extend through the vessel and a rotor member coupled to the stator member to be rotatable relative thereto. A lateral opening in the rotor member is brought into and out of alignment with a lateral opening in the stator member, thereby opening communication to a longitudinal discharge passage through the stator member. One of the members has a projection fitting into a recess in the other member, with complementary sliding sealing surfaces therebetween. The projection comprises an insert formed separately from the respectively member and fixed thereto to be non-rotatable relative thereto.

Abstract: A main body of a bearing (12) is guided on a guide rail (10) by at least one rolling-element circuit (14, 16) and receives at one end an end plate (13). A deflection duct (50, 52) is recessed in the end plate and receives a deflection piece (60), which crosses the deflection duct (50, 52). A lubricant-supply system (86) for the rolling-element circuit (14, 16) is provided inside the end plate (13). The lubricant-supply system (86) is partly within a deflection-piece receiver duct (58) which accommodates the deflection piece (60). The lubricant-supply system (86) includes a lubricant channel (92) which runs entirely within the end plate (13) so that it is encapsulated completely by the material of the end plate (13).

Abstract: A slide gate nozzle for controlling the discharge of molten metal from a spout of a converter vessel includes a refractory bottom plate to be positioned stationarily with a discharge opening thereof aligned with an opening of the spout. A refractory slide valve plate is mounted for sliding movement relative to the bottom plate such that a discharge opening of the slide valve plate is brought into and out of alignment with the discharge opening of the bottom plate. A plurality of refractory shut-off plates are positioned sealingly between the bottom plate and the slide valve plate. A coupling mechanism is operably mounted to the shut-off plates to sequentially connect the shut-off plates rigidly either to the bottom plate or to the slide valve plate. As a result, the shut-off plates may be used sequentially to replace the slide valve plate.

Abstract: The material web (15) is guided through a treatment zone which is formed by numerous collector tubes (33, 34, 35) and by a shaft. Each collector tube is provided with a separate connection (36, 37, 38) and can be fed with its own treatment medium. The collector tubes preferably form a unit which is adjustable through a limited range in relation to the fabric web (15). Through the combined use of liquid and gaseous treatment mediums (44, 45, 46) an intense effect can be achieved, for example for washing, impregnating or similar.

Abstract: A unit for controlling the discharge of molten metal from a metallurgical vessel includes a valve having a refractory stator fixed to refractory material of the unit constituting lining of the vessel and a refractory rotor disposed in the stator and movable relative to the stator between open and closed positions of the valve. The stator and the rotor have flow control passageways extending therein which can place the interior of the metallurgical vessel in communication with a discharge opening of the valve. A seal is established between the stator and the rotor over a portion thereof that surrounds the flow control passageways such that molten metal may not pass from the flow control passageways into an area between the stator and the rotor.

Abstract: Stationary and sliding refractory valve bodies of a sliding closure unit, for use in controlling the discharge of molten material from a vessel, are mounted on respective support frames to be precisely centered with respect thereto and to prevent the application to the refractory valve bodies of stresses due to such mounting during operation of the unit. At least one bore hole and at least one elongated groove are formed in the refractory valve body. First and second rods are fixed to the respective support frame and extend therefrom into the bore hole and the groove, respectively. The bore hole is centered on a longitudinal axis of the groove extending in the direction of elongation thereof.

Abstract: A sliding closure unit for controlling the discharge of molten metal from a metallurgical vessel includes a stationary refractory plate, a stationary housing assembly for mounting the stationary refractory plate on the metallurgical vessel, a movable refractory plate, the stationary and movable refractory plates having complementary, abutting relative sliding surfaces, and a movable frame mounting the movable refractory plate for movement with respect to the stationary refractory plate. The movable frame and movable refractory plate are urged toward the stationary refractory plate by levers mounted in the housing assembly for pivotal movement about axles fixed to the housing assembly and extending transverse to the direction of movement of the movable frame and movable refractory plate. Springs are mounted in the housing assembly to urge the levers to pivot about the respective axles toward the movable frame to thereby urge the movable frame and movable refractory plate toward the stationary refractory plate.
