Abstract: A method and apparatus of a device for obtaining a geometric representation of an object including a thin structure having a first surface and a second surface; generating one or more 2D blocking faces as a simplified representation of one of the first surface or the second surface; generating one or more 3D blocks based on an extrusion of the one or more 2D blocking faces; and determining a 3D mesh of the object based on the one or more 3D blocks.

Abstract: An adjustable chargehole closure for adjusting the closure cover of a charging hole in a coking oven chamber. The adjustable chargehole closure has as an inner frame for a closure cover, and the frame can be rotated both with respect to the closure cover and with respect to an outer frame, designed asymmetrically with respect to a vertical plane, so that the closure cover is displaced along a longitudinal axis when the inner frame is rotated in the horizontal plane. The position of the charging hole opening and the closure cover present therein on the ceiling of a coking oven chamber can thereby be changed without requiring construction measures on the ceiling of a coking oven chamber. The capability is in particular advantageous in order to match the position of the charging hole cover to the precise charging position of the charging machine.

Abstract: A coke-oven battery has at least two chambers separated by a heating wall head and having openings provided with vertical jambs juxtaposed with the head. An upright anchor post is spaced horizontally forward from the head, and a plurality of U-shaped yokes are provided between the post and the head. Biasers bear on the anchor post and press the yokes against the jambs and thereby press the jambs against the head. A thin-walled sheet-metal head cover having upright edges is clamped between the jambs and the head and extends horizontally as a single piece between the jambs.

Abstract: The invention relates to a wall protector for a heating oven head (2) between two oven chamber openings (1, 1?) of a coke oven battery, said wall protector being laterally bounded by vertical frame elements (5, 5?). The wall protector comprises an anchor stand (4) arranged in front of the heating wall head (2), extending vertically, and pressing devices (6) fixed to said anchor stand (4). Additionally, the wall protector has U-shaped yoke elements (7) onto which pressure is exerted by the pressing devices (6), and a rectangular head cover (10) covering the heating wall head (2). According to the invention, the U-shaped yoke elements (7) fit tightly against supporting surfaces of the frame elements (5, 5?) in a force-fitted manner and the head cover (10) consists of a thin-walled metal sheet constrained between the frame elements (5, 5?) and the heating wall head (2).

Abstract: A sputter ion source includes an ionizer; a sputter cathode, including a cathode, a sputter insert, and a shielding cap; a forming electrode; cathode insulator; a hollow, cylindrical shielding cathode, surrounding the sputter cathode, and tapered rotationally symmetrically in the region of the sputter insert; and a vacuum-tight housing for enclosing all of the foregoing. The sputter ion source has a prolonged operating life, low maintenance costs, and prevents atomization of parts of the ion source, for generating negative ions, in the vicinity of the cathode insert.

Abstract: It is an object of the invention to prolong the service life of a sputter ions source, to lower the maintenance costs and largely to prevent atomization of the parts of the ions source, which are in the vicinity of the cathode insert, necessary for generating the negative ions.

Abstract: A large-scale coking reactor including a housing provided with a chamber and with outer and inner chamber frames, a displaceable outer door elastically compressed against the outer frame and formed with a respective elastic peripheral seal compressible against the frame and with an outer high temperature membrane interposed between the door and the seal and elastically pressed thereagainst to seal the door opening, a displaceable inner door spaced from the outer door and formed with an inner high temperature membrane interposed between the inner door and the inner frame to fit elastically the inner frame, the inner and outer doors being releasably interconnected upon displacing the outer door, so that the doors are mounted in the housing to be operatable either selectively or in combination with one another.

Abstract: A latch assembly is disclosed for latching a leveling door used to close a leveling rod opening which is surrounded by a seal in a leveling box at the upper portion of a coke-oven door. The latching assembly includes spaced apart side flanges connected together at one of their ends by a cross web. The opposite ends of the flanges carry a rod which, in one embodiment, engage claws on arms extending from the leveling box and in a second embodiment the is pivotally connected with arms extending from the leveling box. In the first embodiment, an arm extends from a leveling door and forms a pivotal connection with retaining members that are in turn, secured to a spring plate.
