A filler made of glass beads is provided. The glass improves the absorption and the distribution of the energy of the beam such that an internal wall of the hollow component is not damaged. A process for producing a through-hole in a hollow component is provided. Also, an apparatus for laser drilling is provided.

A method for preparing a blade of a turbomachine for a spray coating process is provided. The method includes providing a sheet of flexible material which is shaped such that, when the sheet is bent circumferentially around a blade root of the blade along a longitudinal axis of the blade, the sheet forms a circumferential cover on the surface of the blade root, and bending the sheet around the blade root to form the cover. The sheet is positioned on the blade root up to a platform between an airfoil and the blade root. The sheet is placed on the blade root such that the sheet forms a circumferentially closed structure around the blade root. Further, an arrangement for a spray coating process is provided.

A shielding device for shielding a root of a blade or a vane for a spray coating process of the blade or the vane is provided. The shielding device includes a removable insert having a first member with one or more projections sized to sealingly fit into corresponding one or more grooves over an exposed part of the root of the blade or the vane, a second member with one or more projections sized to sealingly fit into corresponding one or more grooves over a remaining part of the root of the blade or the vane, wherein the first member and the second member are adapted to be coupled to sealingly fit on the blade or the vane.

A mine, especially an antitank mine, that can be laid on the ground surface by being dropped from the air and that impinges on the ground in a preferred impact direction includes a detonator and an explosive charge located in a housing. The housing is subdivided into an operational part containing the detonator and into an active part containing the explosive. Both the active and operational parts are coupled together by a shape-mating connection. The shape-mating connection is severed when a predetermined impact load on said mine has been exceeded and at this time the active part is separated from the operational part by the impact shock.

A vehicle brake control wherein a driver generated braking prompt signal is compared with a measured deceleration signal and, according to which, a correction signal is generated. The correction signal is processed with the braking prompt signal into an output signal. The correction signal is constantly maintained over one or more clock pulses when the value of the deceleration signal lies within a given value range or tolerance band. However, the correction signal is changed from one plus to the next when the instantaneous deceleration lies outside said tolerance band.
