    摘要: A method for replacing a fuse casing (4), which is riveted to the casing (2) of an active component (1) containing an explosive charge (3). The new fuse casing (4) laser-welded to the remaining rivet parts (5) of the active component casing (2). Welding filler materials are used to attach the new fuse casing (4) easily and securely to the active component casing (2), such that the connection can withstand even high firing accelerations, without this resulting in impermissibly high thermal stress to the explosive charge (3) in the active component. Welding powders (7) or welding pastes can be used as welding filler materials, which are inserted into gaps (8) remaining between the remaining rivet parts (5) and the bores (6) in the fuse casing (4) before the remaining rivet parts (5) are welded to the fuse casing (4). Also used are discs (9) that cover the bore holes (6) in the fuse casing (4). The disks are placed onto the frontal faces of the remaining rivet parts (5) and are welded to these.

    摘要: A method produces homogenous quartz glass plates without streaks. The method is applied to starting quartz glass body which has an X—X geometrical axis and good refractive index homogeneity in its central area, and a refractive index homogeneity decreasing as the axis lies further from a central area. The body is divided into at least two concave parts by longitudinal cuts parallel to the axis once the central area has been processed out of the body. The parts are placed separately in corresponding molds and heated therein such that they are molded to form quartz glass plates having a desired thickness.

    摘要: In a method for producing a streak-free quartz glass sheet with a highly homogeneous degree of refraction, a quartz glass rod is lowered into a melting pot parallel to a longitudinal axis of the quartz glass rod. A cross-section of the melting pot is larger than a cross-section of the quartz glass rod and determines a contour of the quartz glass sheet. The quartz glass rod is heated in the melting pot to a flow temperature whereupon the quartz glass rod is lowered until the quartz glass rod melts and a height of the quartz glass flowing in the melting pot reaches a desired quartz glass sheet thickness. The melting pot and the quartz glass rod move relative to each other in a direction which is perpendicular to the longitudinal axis of the quartz glass rod during the melting process. Preferably, the movement involves a rotational and a transverse movement.
