Abstract: A transparent safety panel for producing resistant, surface flush butt joint glazing, including two plates and a receiving profile. The two plates are spaced apart from each other and are arranged substantially parallel to each other. The safety panel has an abutting end side and a mounting end side extending at a right angle from the abutting end side. The mounting end side can be mounted in the frame and permit fixing of the safety panel in the frame. The receiving profile is arranged between the spaced apart plates in a border region in the vicinity of the abutting end side. The receiving profile forms an open groove towards the abutting end side. A further safety panel can be connected to the safety panel in a surface flush manner without an additional frame via the abutting end side of the safety panel with the groove.

Abstract: There is provided a bustle pipe arrangement of a shaft furnace, in particular for feeding hot gas into the shaft furnace such as e.g. a blast furnace, wherein the bustle pipe arrangement comprises a circumferential bustle pipe arranged along the outer casing of the shaft furnace, at a certain distance therefrom. The arrangement further comprises a plurality of first support arms connecting the bustle pipe to the outer casing of the shaft furnace on a first level; and a plurality of second support arms connecting the bustle pipe to the outer casing of the shaft furnace on a second level, the first level being separate from the second level. The first and second support arms are configured to support the circumferential bustle pipe. First blow channels are arranged through the first support arms for fluidly connecting the bustle pipe to the interior of the shaft furnace.

Abstract: A device for regulating the temperature of a gas in a hot gas main for feeding hot gas to a blast furnace includes a mixing pot with two mixing chambers in fluid communication with each other by means of a Venturi restriction. The first mixing chamber includes three inlet ports for feeding hot gas into the first mixing chamber, feeding cold gas into the first mixing chamber and feeding cold gas into the second mixing chamber, respectively. The first mixing chamber further includes an outlet port for feeding a first stream of mixed gas from the first mixing chamber to a first gas distribution system. The second mixing chamber includes a second outlet port for feeding a second stream of mixed gas from the second mixing chamber to a second gas distribution system. The first and second streams of mixed gas have different temperatures.

Abstract: A gear train includes at least one planetary gear stage and one gear train stage. One end of a sun shaft of the planetary gear stage is concentrically surrounded by a hollow shaft of the second gear train stage. The sun shaft of the planetary gear stage is co-rotationally coupled to the hollow shaft by a denture clutch. A lubricant feed ring is arranged at a front face of the hollow shaft facing toward the sun gear of the planetary gear stage and has a cone-shaped passage opening, which has an internal diameter which decreases in the direction of the sun gear of the planetary gear stage, and concentrically surrounds the sun shaft of the planetary gear stage. At least one lubricant feed nozzle is aligned with a circumferential gap between the lubricant feed ring and the sun shaft of the planetary gear stage.
