Abstract: An antenna for an electronic projectile detonator. A desired antenna pattern which is rotationally symmetrical to the longitudinal axis of the projectile is produced by designing the antenna as a dipole which is fed via a coaxial line and which is decoupled from the feeder line by a .lambda./4 wave trap. The dipole is realized by a frustoconical widened portion of an extension of the inner conductor of the coaxial feeder line, which widened portion constitutes the detonator head in the tip of the projectile and coincides, as regards position and direction, with the longitudinal axis of the projectile at the feed point of the antenna, and the wave trap which is also designed to be rotationally symmetrical to the longitudinal axis of the projectile.

Abstract: A method and apparatus for determining the deposition of particles in the respiratory tract and/or for checking the operating function of the respiratory tract by means of pulses of gases or aerosols injected into a stream of air inhaled by a test patient and by obtaining a measuring signal in each of the inhaled and exhaled streams. The main stream of the inhaled and exhaled air is conducted directly through a band of light (3), and the region of the intersection of the band of light with at least part of the inhaled and exhaled streams is placed in the object plane of an optical image system for a light measuring device. Either the individual pulses generated by the individual particles in the inhaled and exhaled streams or the scattered radiation emanating from the gases and aerosols in these streams is measured to obtain the ratio of the exhaled to the inhaled numbers of particles and/or the concentration profile in the inhaled and exhaled streams.

Abstract: Method for producing nuclear traces, or microholes originating from nuclear traces, from a single ion or a countable number of ions in a solid body by means of an accelerator, e.g. heavy ions in a heavy ion accelerator. A widened or attenuated beam or ions is directed onto the surface of a solid body via a preliminary aperture to cut out any non-required particles. The impinging of an individual particle, after or before passage through the solid body, is determined directly and depending of this determination, other particles which might possibly pass through the aperture are prevented from doing so.

Abstract: Apparatus for evaluating optoelectronically generated picture rasters wherein, for the purpose of regulating the tape movement of a tape-shaped material (tape), the tape position is detected with the aid of a video camera by continuously reproducing an edge of the tape or a marking line on the tape as a sudden change in contrast, each picture raster or frame is scanned line-by-line for the purpose of evaluation and the picture elements in each line occurring up to the selected sudden change in contrast are counted by means of a picture element counter, and the count is used to provide an analog output signal, by means of a digital/analog converter, which is used to form a setting instruction to mechanically adjust the tape position to the desired position. The input signal to the digital/analog converter is provided by the output of a second counter which serves as a memory having a counting content of picture elements corresponding to the previously detected tape position.
