For the purpose of reducing manufacturing costs and mounting defects, an electric ignition device has a one-piece basic body as a base for a primary and a secondary charge, so that the tightness is also increased with respect to moisture penetration.

Ignition device

The innovation relates to an electric ignitor for a pyrotechnic element hng a rotationally symmetrical electrical plugging arrangement comprising two plug elements connected together and with a short-circuiting spring being open in the progress.

Plug connection for an electric ignitor

A shock wave generator for the fragmentation of concrements, having a light-pulse-transmiting light guide and a converter arranged at the distal light guide end and having an ionization surface which, when a light pulse impinges, initiates a shock wave in the surrounding fluid, as well as having a shock wave outlet zone. In order to increase its efficiency and durability, the generator is constructed such that the ionization surface extends obliquely sloped with respect to the beaming axis of the impinging light pulse and the shock wave outlet zone is arranged in the direct shock wave beaming area of the ionization surface, thereby permitting a largely unhindered, low-loss propagation for the shock wave to the application point.

Shock wave generator

An apparatus for the fragmentation of a solid body surrounded by a fluid, in particular in a living being, by means of acoustic shock waves which are induced by the light of a laser. A reflector for acoustic waves focuses the shock waves onto the body. In the region of the reflector, an element is provided which consists of a material absorbing the laser light, and onto which the laser light is directed, so that the plasma state triggering the acoustic shock wave develops at the surface of the element. The apparatus thus has the advantage that even under unfavorable conditions acoustic shock waves can be generated with certainty at every laser pulse.
