    摘要： A laser diode gas sensor for the spectroscopic measurement of a gas sample, with a retroreflector and a concave mirror, which define between them an open measuring path with the gas to be analyzed. Laser light passes through the measuring path, is reflected at the retroreflector, and is directed toward a detector via a concave mirror in order to determine the mean concentration of the gas component to be analyzed in the optical measuring path. Optical elements, such as beam splitters, lenses, etc., which lead to losses of intensity, were used before to couple the laser light into the beam path onto the retroreflector, and to decouple the reflected light to the detector. An improved optical imaging array, which minimizes losses, is provided. The concave mirror is provided centrally with an opening transparent to the laser light, through which a weakly divergent bundle of laser light is directed onto the retroreflector, so that the retroreflector is illuminated essentially over its entire surface. The retroreflector is made with a matrix consisting of a plurality of triple mirrors, which reflect the incident, weakly divergent bundle of laser beams as a bundle of laser beams with convergent properties onto the concave mirror. The concave mirror is arranged or shaped such that the laser light reflected by the retroreflector is focused by the concave mirror directly onto the detector, which is arranged outside the principal beam path.

    摘要： A device for actuating an ignition mechanism of an oxygen-releasing mechanism in a respirator, with a striker spring fastened in a mounting support and with a striking hammer, which is located at the free end of the striker spring and actuates the ignition mechanism. The striking hammer can be released several times in succession, whereby the replacement of the cartridge is facilitated. The device is provided with a release lever, which can be pivoted from a starting position around a fixed axis and has a tensioning tongue, which extends, at least partially, below the free end of the striker spring and deflects the striker spring in the pretensioning direction. The release lever has a return member automatically restoring the starting position. The mounting support and the axis are fastened to the receiving housing of the respirator, which accommodates the cartridge.
