Abstract: Continuous method of manufacturing coil type slide fasteners by forming synthetic monofilaments into a pair of uncured fastener element coils. The fastener coils are then intermeshed in coupled relation and sewn onto the adjacent edges of a pair of uncured knit tapes. The coil, sewing thread and knit tapes are each composed of the same thermosetting resin. The fastener chain is advanced at uniform tension and velocity through a pressing stage (25) and viscous dye bath (30) containing a dispersion type thermosoling dye. The advancing chain is then vacuumed (40) to provide uniform deposition of the dye on the tape and coil. The chain is then dried (45) and led through a heating zone (50) maintained at a temperature which simultaneously fixes the dyestuffs and cures or thermosets the coil and knit tapes. Thereafter, the moving chain is washed (60) and calendered (65) while being maintained under tension. The continuous zipper chain is then cut to length and supplied with a slider and end stops (75).

Abstract: An apparatus is provided for causing circulation within a large standing body of fluid, for a body of liquid containing sewage. The apparatus comprises a large-bubble generator (20) exposed to the pressure of the fluid at a predetermined level, a vertically extending standpipe (18), an inverted siphon (23) between the standpipe (18) and the generator, and a transverse connection (15) between the standpipe (18) and a vertically extending stackpipe (13). Upon generating a large gas bubble into the stackpipe (13), the gas acts as a piston within the stackpipe (13), pushing liquid upwardly therethrough, and thereby drawing liquid into the bottom. The continuous passage of such large bubble through the stackpipe (13) results in a current flow circulation through the large standing body of liquid. The generator can be placed at a position beneath the surface of the standing body of liquid a distance limited only by the rapidity at which a large bubble can be generated, as it is desirable that in steady state operation, a large bubble enter the stackpipe before the preceding large bubble has exited from the top.

Abstract: Thermoplastic yarn is texturized by the known method of forwarding it in a heated condition to a crimping zone at the entrance of a stuffer chamber 7 so as to form a plug 8 of crimped yarn within the chamber and withdrawing the yarn from the other end of the plug at a speed which is related to the inputspeed.The improvement comprises deriving signals from the speed of the yarn plug 8 in the stuffer chamber 7 by means of a sensing wheel 11 which drives a gapped monitoring disc 13. The disc 13 operates to intercept a beam of light from a source 14 which is directed on to a photosensor 15. The output of the photo-sensor is supplied to an electrical controller 36 which measures the time during which light is received for each gap in the disc 13 to provide a measure of the speed of the yarn plug. The resultant signals are used to control the temperature of the yarn passing to the crimping zone in such a way asto maintain the speed and hence the quality of the bulk yarn substantially constant. For this purpose the signals from the controller 36 are fed to a heater controller 28 to adjust the current to a heating element 5 in a chamber 4 through which steam passes before feeding the yarn 1 through a jet passage 2 leading to the chamber 7.

Abstract: A pair of optical fibres 16, 19 which are to be joined are located with their end portions in coupling elements 15, 18 one of which is transparent to light. The coupling elements are located such that the ends of the fibres are in approximate alignment. Light is transmitted along one fibre 16 so that it is received by the fibre 19 in the transparent coupling element. Light which is not coupled into the core of the fibre 19 is sensed by a sensor 20 and the relative position of the fibres is adjusted until the level of sensed light is a minimum. The sensing of the light is carried out at positions spaced angularly about the waveguide so that an indication of the direction of any misalignment is obtained. The coupling elements are then secured in this position. The adjustment of the fibres can be carried out using a linear translation stage 10 and a microprocessor 25 which controls the stage 10 in accordance with signals from the sensor 20.
