Abstract: The present invention relates to a shaped article comprising an elastomeric material, a process for making the shaped article and the use of the shaped article for forming an thermal and/or acoustic insulation, acoustic and/or vibration damping, mechanical protection and/or for applications requiring load bearing as well as a structure, such as a pipe, a pipework, a tank or a vessel, having an insulation formed from the shaped article. The shaped article has a planar form with two main sides and a plurality of tapered recesses formed in one of the main sides. The tapered recesses form each a pointed angle and the sum of the pointed angles of all tapered recesses is 300 to 355 degrees. The protrusion of the recesses into the form is more than 20% but not more than 80% of the thickness of the planar form.

Abstract: The invention relates to a method and a device for cleaning the door of a coke oven, said door comprising a sealing edge and a membrane that is attached to the door panel of the coke oven. According to said method, cleaning tools comprising jet nozzles, which are supplied with a flow medium at high pressure, are situated and displaced back and forth in the region between the sealing edge and the door panel of the coke oven, in such a way that the interior surface of the membrane and the sealing edge are cleaned. The coke oven door is cleaned directly after the coke oven chamber is opened, by at least one jet nozzle element, which is supplied with compressed air and is displaced along the sealing edges. The jet nozzles are oriented in such a way that the air hits the surface to be cleaned at an acute angle.

Abstract: A coke-oven door has an annular periphery normally juxtaposed with an annular door frame. A seal assembly for the door has at least two flexible, relatively displaceable, metallic, and annular membranes each having an annular inner periphery and an annular outer periphery and a U-section channel fixed to the outer periphery of only one of the membranes, open toward the door, and having annular inner and outer edges. The other membrane bears on the one membrane and therethrough on the channel. A mount secures the inner peripheries of the membranes to the periphery of the door. A spring urges the edges of the channel with a spring force against the door frame.

Abstract: The invention relates to a seal for coke oven doors comprising an encircling door frame, which is closed at the top on the oven chamber and which has even sealing surfaces on the exterior thereof. The inventive seal also comprises a door body, which can be fixed to the door frame, and comprises an encircling sealing element, which is attached to the door body and which rests against the door frame when the door is closed. A comb-shaped sealing strip (1) having a sealing edge (2) and notches (3) is attached to the door body.

Abstract: 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.

Abstract: The invention relates to a coke oven door (1) with a gas channel that substantially encloses the oven door and a membrane that is fastened on the coke oven door (1) and that can be forced against the chamber frame against the action of a spring. The gas channel (5) is fastened on an at least bilayered membrane (3).

Abstract: The invention relates to acarviosyl transferase from actinomycetes, mainly from Actinoplanes sp. SE 50/110 and its mutants, to a process for isolating, purifying and characterizing the enzyme, to the isolation and characterization of the acbD gene encoding the acarviosyl transferase, to the expression of the acarviosyl transferase in a heterologous host organism, to the use of the acarviosyl transferase for converting acarbose minor constituents into acarbose or for preparing acarbose homologues, to the use of the acarviosyl transferase in acarbose purification, and also to the preparation of production mutants in which formation of minor constituents is reduced by means of inactivation of the acarviosyl transferase gene.

Abstract: The present invention relates to the new use of p-hydroxyphenylacetic acid, by itself or in a mixture with other chemical compounds, for reducing the repellency of insecticides in the control of cockroaches, and to cockroach control compositions which comprise these mixtures, details being found in the description.
