<p>1,215,327. Pneumatic gauges. TOKYO KOKU KEIKI K.K. Dec.27, 1967 [Jan. 10, 1967; Feb. 17, 1967; (2) March 9, 1967; Oct. 14, 1967], No. 58746/67. Heading G1M. Apparatus for detecting a break or other abnormality in a fast moving thread or filament comprises two opposing nozzles, 1, 4 Fig. 4 each supplying gas to form a Collision plane; passage of the filaments between the nozzles provides a back pressure which is modified by a break or other change in the filament. The reacting signal may be fed from outlet B to a fluid controlled OR-NOR element 2 Fig. 1 to change the flow of control fluid from path 'a' to path 'b' which may be applied via a fluidic amplifier, to an indicator, counter or cutting apparatus. A plurality of pairs of opposing nozzles may be used to improve the signal.</p> |
