Abstract: A water separator is disclosed for removing water from a minute flow of gas/water sampled from a patients exhalation and prior to the gas being introduced into an analyzer. The separator comprises a housing with an inlet (l8), an outlet (38), and a pair of chambers (24, 30) in series through which the sample is drawn. The first chamber (24) has a pair of substantially closely aligned wall surfaces of predetermined narrow distance from each other such that the surface tension causes the liquid in the sample to adhere to the wall surfaces. As the sample progresses to the second chamber (30), the wall surfaces are further apart and thus the tension effect is broken and only the gas continues through the second chamber (30) to the separator outlet (38). A drain (40, 42) is located in the lower part of the first chamber (24) for withdrawal of the accumulated liquid from that chamber.

Abstract: The device comprises two rods (11, 12) which are each intended to be connected to one of the structural elements (3, 5) and at least one helical spring (15) whose ends are connected to two discs (13, 14), each associated with one of the rods (11, 12), so as to oppose the movement apart of the rods (11, 12) through the discs (13, 14). The latter are mounted for axial sliding relative to the associated discs (13. 14) and are formed in such a way that their movement both towards and away from each other causes tensioning of the spring (15) from its undeformed rest condition. The device acts as a rigid connecting element when the stresses applied to it are less than a predetermined threshold. When the stress exceeds the threshold, however, it deforms resiliently to limit the amount of stress transmitted to the members (3, 5) between which it is connected.

Also claimed is a measuring process for monitoring the degree of filling of a continuous casting mould with powder covering the melt surface in which the casting stream is detected and the disappearance of the stream in the powder is used as a measurement signal of the level in the mould.

Abstract: A semiconductor light modulator is disclosed. The light modulator comprises a semiconductor body and a waveguide for guiding light rays formed in the body. The waveguide comprises waveguide sections of first and second types formed alternately in a series. Each waveguide section of the first type is delimited at least in part by a depletion zone. A voltage U may be applied for controlling the size of the depletion zone delimiting the sections of the first type to vary the ability of the sections of the first type to guide light. Illustratively, when the voltage U is near zero, the light confining characteristics of the sections of the first and second type are substantially identical, so that light rays are guided along the waveguide from one section to another. When the voltage U is increased so as to increase the size of the depletion zones delimiting the waveguide sections of the first type, then there are losses within the waveguide sections of the first type and at the interfaces between the waveguide sections of the first and second type. Thus, the voltage U may be applied to selectively modulate the intensity of light propagating in the waveguide.

Abstract: An apparatus for counting a number of record tracks which an optical head (2) traverses on a basis of a periodical track transverse information INFTR representing the traverse of the head across the record tracks. The periodical track transverse information INFTR is derived by sampling a track information of the record tracks preformed discretely on record tracks TR. In the track counting apparatus (6), a tracking signal generating circuit is installed for generating tracking signals VOP and VOQ which vary their frequencies and phases so as to follow those of the track transverse information INFTR. The number of record tracks which the optical head (2) has traversed are counted on the basis of the tracking signals VOP and VOQ. The tracking signals VOP and VOQ have continous waveforms so that the number of the tracks can accurately be counted even if only a discrete information is derived as the track transverse information INFTR.
