Title: Improvements relating to Capacitive Voltage Transformers
IPC: H02H9/00
Filed: 1968-01-03
Abstract: Ferroresonant oscillations in a capacitive voltage transformer 1 are suppressed by the circuit arrangement shown, in which the occurrence of such oscillations triggers a bi-directional semi-conductor switch 4 to connect a damping burden 3 across the intermediate voltage transformer 2, the triggering being effected by a relaxation oscillator which supplies a train of firing pulses to ensure that the switch 4 conducts for the duration of the oscillations. The oscillator comprises capacitors 5, 7, resistors 6, 9 and a voltage-dependent (Shockley) diode 8, the capacitor 5 being connected to a control voltage source 10 for charging when unwanted oscillations occur.

Title: Apparatus for treating yarn with fluid material
IPC: D06B1/08
Filed: 1973-04-18
Abstract: Methods of and apparatus for treating yarn with a fluid material include a chamber through which the yarn is advanced and an injection nozzle for impinging fluid on the yarn as it advances through the chamber. The injection nozzle is registered with a fluid circulation system in which a dyeing substance or other fluid treating substance or material is circulated. Upon interrupting the circulation of the fluid treating material, a portion of the material is diverted into the chamber through which the yarn is advancing. By interrupting the circulation of the fluid treating material according to a selected pattern, the fluid treating material will impinge on the advancing yarn with a corresponding pattern. If it is desired to impinge treating materials having different characteristics, such as dyes of different colors, then a plurality of circuits may be utilized to direct the fluid materials into the chamber through which the yarn advances. The fluid circuits may be controlled and coordinated according to selected patterns in order to produce a varying effect on the yarn progressing through the chamber.
