Patent number: 6929719Abstract: The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates (1), which extend essentially over the entire length of the ranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers (2) which are arranged in the intermediate space delimited by the cheeks (1) at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between he cheeks (1). The height (3) of the coal carriers (2), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks (1) and the cheek form a gas channel (6) above the coal carriers (2) which is essentially free of built-in components.Type: GrantFiled: July 2, 1999Date of Patent: August 16, 2005Assignee: DMT Deutsche Montan Technologie GmbHInventors: Hans-Josef Giertz, Jürgen George, Klaus-Dieter Ruthemann

Patent number: 6884325Abstract: A sealable lid assembly for a vacuum distillation apparatus has a lid pivotally and telescopically mounted to the vacuum distillation apparatus. Spaced-apart wheels are rotatably mounted to the lid. Tracks are disposed on the vacuum distillation apparatus in a position to engage the wheels and raise the lid vertically above a manhole of the vacuum distillation apparatus upon pivotal movement of the lid, which is initiated by nominal physical exertion of a single operator. Extending outwardly from and adjacent the manhole is a flange. The flange has a channel to receive a gasket. A protrusion extends outwardly from a bottom of the lid in a position to extend into the channel and sealably engage the gasket when the wheels disengage the tracts. Clamp assemblies are provided to releasably engage the lid with the flange and draw the protrusion into sealable, releasable engagement with the gasket.Type: GrantFiled: April 7, 2000Date of Patent: April 26, 2005Assignee: IHS Solvent Solutions, Inc.Inventors: Michael D.
