Abstract: A plastic ferrule (1) for optical connecting systems, in which a optical wave guide (3) of an optical fibre (6) is guided through a support element (2), whereby the optical wave guide (3) is surface-conditioned in a partial area (4) in order to bond in a force-actuated way to a hardened casting mass (5) in this partial area (4).

Abstract: An optical plug connector comprises a socket part, adapter part or coupling part with a socket housing for releasable connection to a plug part. An inside of the socket housing defines an inner space, into which a plug portion of the plug part may be introduced. Moreover, a switch device is present, by way of which a radiation power led to the plug part and/or the socket part, adapter part or coupling part (1) may be reduced or switched off when the plug connection is released. The switch device comprises a first element which is present or fastenable on the socket part, adapter part or coupling part, and a second element which is present or may be fastened on the plug part, wherein the switch device is actuated in that the first and the second element cooperate.

Abstract: The invention specifically relates to a plug-and-socket connection part (1) of a plug-and-socket connection for a data transmission cable with a plurality of electrical conductors, comprising a connection housing, and per electrical conductor, a connection contact element (31) held by the connection housing, in each case with one insulation displacement contact (31.1) or a piercing contact, for contacting the electrical conductor, as well as in each case a contact (13.1) for contacting corresponding contacts of a corresponding counter piece with the plug-and-socket connection part. Each insulation displacement contact (31.1) or each piercing contact is electrically connectable to one of the contacts. The invention is characterized essentially in that the connection housing is shaped, such that the connection contact elements (31) may not be introduced from the outside into the connection housing.

Abstract: A filter element formed of a pleated filter medium (11) and having a seal or gasket element (15) on its periphery or end faces. On one side of the filter element, which may represent either the inlet or the outlet side of the filter element, at least one adhesive track or reinforcing member (12, 13, 14), and preferably at least two adhesive tracks or reinforcing members (12, 13, 14), is/are arranged in such a way that the filter element can be bent to a curved configuration in one direction.

Abstract: Slabstock foam may be produced, in particular in larger dimensions, in homogeneous form and with less waste, by introducing a foam-forming reaction mixture into a stationary moulding box, transporting a mobile foaming station (preferably on guide means) over the molding box, curing the foaming reaction mixture, optionally under defined pressure conditions, transporting the foaming station away from the molding box, and, demolding and removing the slab of foam from the molding box.

Abstract: 1-(4-Chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid carboxymethyl ester as known per se is obtainable by a novel and more simple method comprising mild acid hydrolysis of 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetoxyacetic tetrahydropyran-2-yl ester. The final product is a valuable drug having antiinflammatory activity.

Abstract: A pressure vessel including a cylindrical vessel shell body, a bottom, and a cover, which are composed of cast elements and are clamped together or restrained by axial prestressing tendons located in channels which are distributed over the periphery of the cylindrical shell body, have axes which are parallel to the axis of the vessel, and by tangential prestressing cables located in annular channels on the outer surface of the vessel. The pressure tank also includes a steel liner which is anchored by means of a special gun welded or bolt connection directly to the inner side of the tank shell body. This tank shell body includes at least two cylindrical shells which are formed of cast elements and are successively arranged when viewed in the radial direction.

Abstract: 1-(4-Chlorobenzoyl)-5-methoxy-2-methyl-3-indole acetic acid as known per se is obtainable by means of a novel and more simple method. This method comprises hydrolizing 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-3-indole acetic acid tetrahydropyranyl ester, which ester is a novel compound. The final product obtained is a valuable drug having antiinflammatory activity.

Abstract: A regenerator lining for regenerator chamber cells in coke ovens, comprises a stone or brickwork having either a honeycomb or lamellar structure, with a plurality of gas passages extending therethrough and terminating in openings on the top and bottom sides of the structure. The transverse portions or sides are made of frame portions having a material thickness of up to 20mm. The webs or spacing between the openings is up to 10mm in thickness. In the case of circular, hexagonal, or similar shape passages, the openings have diameters of up to 16mm and in a construction which includes a slot formation, the slots are made up to 16mm wide.
