Abstract

This apparatus provides an in-line detector 10 for two wires 12,14 which is capable of rotating and moving linearly with the wire twisting mechanism 16 and yet is capable of providing a stationary fluid outlet 18. The apparatus consists generally of a pressure manifold fluid 20, mounted on sealed ball bearings 22, which does not rotate with the rest of the system thus providing an output coupling. The detector 10 can be directly plugged in line with the twisting mechanism 16 or it can be made a part of the twister itself since it is small and does not add appreciable inertia to the twister 16.

Fluidic Wire Detector

This apparatus provides an in-line detector 10 for two wires 12,14 which is capable of rotating and moving linearly with the wire twisting mechanism 16 and yet is capable of providing a stationary fluid outlet 18. The apparatus consists generally of a pressure manifold fluid 20, mounted on sealed ball bearings 22, which does not rotate with the rest of the system thus providing an output coupling. The detector 10 can be directly plugged in line with the twisting mechanism 16 or it can be made a part of the twister itself since it is small and does not add appreciable inertia to the twister 16.

The detector 10 consists of a mainblock 24 with two parallel axial passages 26 and 28. The diameter of these passages depends on the diameter of the wire being used. The radial ports 30 and 32 are located in the center of the passages 26,28. The block 24 is connected to and rotates with the twister 16 during the twisting operation but the outer manifold 20 does not rotate thus making it possible to connect output port 18 of the sleeve to a Fluidics Switching System. The fluidics system consists of a Schmitt Trigger 34. The control port C1 of the Schmitt Trigger 34 is connected to the outlet 18 of the manifold 20 while the control port C2 has a biased pressure. This bias pressure is set such that with wires 12,14 present in the feed passages 26,28, the output through port 02 of the Schmitt Trigger is 1 while the output at port 03 is 0. The port 03 is co...
