In order to ensure that the thread is drawn off without tension, the needle thread spool fitted on a central sleeve (1) is inserted into an outer sleeve (2) and axially uniformly pressed from both faces by piston rams (3) with the application of heat. This fully stress-relieves the needle thread spool (4) so that neither the material nor the seam is prestressed. Thus undesired tension curling phen...

On a two-fold doubling frame, yarn is spliced automatically by a service robot which picks up the ends from both supply reels, having been forced upwards by air pressure. Auxiliary pressure is also given to the anti-ballooners, so that a suction tube can pick up both threads at the tension section, to lift them across a thread separator, and into the double splicer. At the same time a suction tube...

Fluid from a producing well is accumulated in an accumulator (10) and allowed to separate into free water, a water-continuous phase and an oil-continuous phase; the separated fluid flows through a monitor (30) having electrodes (104-106;152-157) exposed to the fluid; a power source (125) provides an AC voltage and current to the electrodes and provides an injection voltage signal (Vi) and an injec...
