The units (16) can be adjusted to eliminate play and thereby ensure that tipping moments acting on the be...

Compressed air splicer has a yarn cutter with a cutting blade at less than 90 deg. to the yarn axis ends can be introduced into opening tubes by guide layers. When an end break is detected, yarn grippers bring the yarn ends (9, 11) into the splicing channel (10) along the direction shown in dotted lines. Cutters (7, 8) cut the ends at an angle of less than 90 degrees to produce an extended end whi...

An optical spectroscopy system, wherein a pulse of a radiation to be analysed is sent to a diffractive element (2) presenting high temporal chromatic dispersion, and information relevant to the radiation spectrum is obtained from pulse broadening in the time domain.
