Prior to the actual splicing process, a preparation process is carried out in a preparation apparatus. The apparatus comprises a preparation tube having one or more circumferentially arranged air jet nozzles. The axis of each nozzle is inclined to the axis of the preparation tube and has a mouthpiece at the inlet end. The yarn end to be prepared is introduced into the preparation tube, where it is...

The two threads (83, 84), coming from opposite ends, are inserted into the splicing device (85). The end of each thread (83, 84) is then caused to be at a pre-set distance from the splicing device (85). Then, each thread end (83', 84') is thrown into vibration, is loosened, combed, unravelled so as to form individual fibres, is cleaned and expanded by means of compressed gas, which flows obliquely...

PURPOSE:To imporve the reproducibility of desired optical characteristics by irradiating an optical fiber or rod which has a refractive index distribution successive in a sectional direction with a radiation, and distributing its sectional light transmittivity. CONSTITUTION:A graded index type glass rod has a sectional center part made of only quartz glass by an inner side CVD method and also has ...

There is disclosed a needle assembly comprising a needle, a needle-retaining portion, a removable needle protector portion, and a resilient member for removing liquid from the surface of the needle which is disposed around the needle rearward of its point. The liquid removing member has a needle-accommodating opening with a diameter approximately that of the outside diameter of the needle. The mem...

A system for controlling the propulsion on motor vehicles which not only enables the output torque of the drive unit of the vehicle to be utilized in an optimum manner in critical driving situations, especially under extreme road conditions, but also endows the vehicle with good stability and enhanced driving safety. A comparator is provided, in a propulsion control system which is triggered by at...
