Title: Improvements in or relating to processes for decoloring thermoplastic materials composed on a polyvinyl halide basis
IPC: C08J7/12
Filed: 1947-04-28
Abstract: Articles made from vinyl halide polymers and copolymers are decoloured by swelling in a solvent and treating with hydrogen peroxide.  If the treatment decreases the content of softening agent or stabilizer, the article may be after-treated with a softening agent in which, if desired, a stabilizing agent is dissolved.  In the example, a polyvinyl chloride foil containing tricresyl phosphate is swollen in tetrachlormethane at 80 DEG  C. and hydrogen peroxide solution added.  An electric conductor having an extruded covering may be similarly treated.

The heating element 3 is actuated by closing a time delay switch Si which opens automatically after the thermistor Xi registers a temperature high enough to switch transistor T 1  to non-conducting and transistor T 2  to conducting energizing a relay RL and completing a circuit for the heating element 3. At a predetermined temperature difference the transistor T 1  conducts and transistor T 2  ceases to conduct thereby breaking the circuit to the heating element. The circuit remains energized. In a modification, the switch is a push button switch S 2 , and the thermistor X 2  has a resistance R9 in parallel, the resistance being significant when cold but insignificant when the system is hot whereby the heating element is energized at the commencement of the drying cycle Fig. 2 (not shown). As shown in Fig. 3 the relay has a second pair of contacts, the second pair controlling energizing a motor 5 and in series with a bi-metallic thermostat 6 whereby the drum continues to rotate after the heating element is switched off to allow the clothes inside the drum to cool before rotation is stopped.

Title: Improvements in and relating to the production of multifilament yarn
Inventor: BEAUMONT ALBERT GORDON
IPC: D01D1/06
Filed: 1959-04-08
Abstract: Multifilament polyolefine yarns, the denier of each filament not exceeding 25, are produced by melting the polyolefine in a screw extruder which feeds the molten polymer to a gear pump which is maintained at at least 300 DEG C. and which forces the polymer through one or more granular filters and then through one or more multi-hole jets maintained at at least 300 DEG C. to form a number of filaments, cooling them immediately they leave the jet by a transverse current of air directed across the face of each jet and subsequently stretching them over a length of path which is not less than the minimum over which the collected stretched filamentary bundle is substantially free from broken filaments, e.g. for producing 1 to 5 denier filaments, a path of at least 4,5 feet.  The length of path is preferably at least 25% greater than the minimum. If the filaments are of high-pressure polythene, they may be stretched at ordinary temperatures, and if of low-pressure polythene, usually at elevated temperatures, e.g. in steam.  The stretching may be about fiveto ten-fold.  The temperature of the gear pump may be 325 DEG  to 380 DEG C., and that of the jet 300 DEG  to 320 DEG C. In the example, a mixture of 90 parts of low pressure Phillips polythene, 10 parts of high pressure polythene and 2 parts of low pressure Ziegler polythene is fed by a screw extruder at 300 to 600 p.s.i. and 270 DEG -280 DEG C. to a gear pump at 340 DEG -350 DEG C. which feeds the melt through a sand pack to 45 hole jets.  The extruded filaments are cooled by a current of air at ordinary temperature flowing across the jet faces, collected, untwisted, as a cheese, passed from a feed godet through a steam chamber 7 feet long wherein they are stretched 9-fold and thereafter collected as a twisted 175 denier /45 filament yarn. The process facilitates the production of multi-filament polythene and polypropylene yarns of low denier.  Specifications 471,590, 472,051, 779,540, 790,195, 790,196, 807,248, 810,023, 818,100 and 905,668 are referred to.
