Title: A method for manufacturing fibrous and microfibrous products
IPC: D04H3/00
Filed: 1966-01-10
Abstract: 1,087,212. Making webs of non-woven fibres. STATNI VYZKUMNY USTAV TEXTILNI. Jan. 10, 1966 [Jan. 9, 1965], No. 1008/66. Heading B5B. A fleece or web of non-woven artificial interlaced randomly arranged fibres is produced by extruding downwards a solution of hereinafter specified viscosity of a polymer such as polyacrylonitrile in an aqueous electrolyte-containing solvent through a spinneret provided with at least one row of extrusion orifices into a space filled with a gas which does not coagulate the polymer and causing a liquid which coagulates the polymer solution to flow downwards through the space at a greater linear velocity than the polymer stream to stretch and carry away the extruded streams of polymer solution while coagulating them while they are still in a plastic and incompletely solidified state, regularly decelerating the fibres thus formed to interlace them in a random manner, drawing them through rollers or the like, and separating the web thus formed from the coagulating liquid. The web of fleece thereby formed is washed, treated in a finishing bath and dried. The polymer solution has ball-fall viscosity at 20‹ C. of at least 500 seconds (steel ball diameter of 3-8 mm., falling distance 20 cm.), the extrusion orifices may have a diameter of about 0-4 to about 2-0 mm. and the stream of coagulating liquid may flow through the coagulation and stretching zone in a direction which is at an acute angle to the spinneret axis. The filaments may be carried downwards by the stream of coagulating liquid through a vertical conduit of rectangular cross-section which tapers towards its lower end and which terminates at the lower end in a slot-shaped outlet. The filaments are caused to become interlaced in a random manner in the conduit and on leaving the bottom of the conduit are deposited as a web of fleece on an endless travelling foraminous belt before being washed and treated. The spinneret orifices may be arranged in two parallel rows each fed with two different spinning solutions. Each spinneret orifice may be fed simultaneously with two separate streams of solutions of two different polymers which when individually formed into filaments produce filaments which differ in shrinkage when heated. Some of the spinneret orifices may be fed with a solution of a thermoplastic polymer, the thermoplastic filament thus obtained binding the filaments of the web together when the web is calendered at temperatures above the softening points of the thermoplastic filaments.

Title: Improvements in or relating to the production of pure titanium or zirconium
Inventor: LEVY JOSEPH PEPPO
IPC: C22B34/14
Filed: 1953-07-02
Abstract: 757,910. Extracting titanium or zirconium. LEVY, J. P., PICKARD, D. H. and PICKARD, L. April 22, 1954 [July 2, 1953], No. 18420/53. Addition to 722,184. Class 82(1). In a process for the production of titanium or zirconium according to the parent Specification wherein an inert gas, e.g. argon, circulating in closed circuit is used as a vehicle to carry magnesium vapour in excess of the stoichiometric amount through a venturi and into a vessel to meet and reduce a current of titanium or zirconium tetrachloride, the inert gas circulated is divided into two interconnected circuits, the major proportion of the inert gas conducting the products of reaction to the collector and being recirculated and the minor proportion being passed from the high-pressure side of the main circuit through the reduction zone and returned to the low-pressure side of the circuit. In the apparatus shown for the production of titanium, the major proportion of the argon circulates through the chamber 51, the cyclone separator 45, the circulating blower 41 and the pipe 35. The minor proportion of the argon is tapped off at 37 from the pipe 35 on the high-pressure side of the blower 41 and is passed through a preheater 40 and a cleaning box 16 containing calcium to a nozzle 21 in a vaporizing vessel containing boiling magnesium. The magnesium vapour is entrained by the argon leaving the nozzle and passes through the venturi 11 and into the mixing vessel 10 meeting a stream of titanium tetrachloride vapour issuing from 15 in the upper part of a reaction vessel 29. The lower part of the reaction vessel is cooled by circulating fluid 30 and the cooled reaction products, titanium and magnesium chloride, fall into the chamber 51 and are carried by the main argon circulation to the cyclone separator. The product collected here is treated to remove the magnesium chloride and unreacted magnesium e.g. by the process described in Specification 757,894. Two cyclone separators may be fitted and the circulating gas may be gathered by collecting and discarding the products of reaction.
