Title: Improvements in the manufacture and production of artificial filaments, threads, bands and the like
Inventor: WORMELL ROBERT LOUIS
IPC: D01F4/00
Filed: 1950-12-13
Abstract: Artificial threads are produced from protein by extruding a solution of a protein into a setting medium, subjecting the freshly-extruded thread to a hardening treatment to render it resistant to cold water and stabilizing the hardened thread against the action of hot water and hot dilute acid by treating it with an aqueous solution containing an ionogenic compound giving rise to cyanic ions in such a manner that the treated thread contains or carries substantially no free chemically uncombined cyanate and then drying the thread at an elevated temperature, preferably between 50 DEG  and 90 DEG C.  In an example stretched lactic casein threads are hardened for 3 hours in an aqueous bath at 55 DEG C. containing in each litre 380 grams of sodium sulphate, 10 grams of formaldehyde and 40 grams of sulphuric acid.  The threads are then washed in water and immersed for 20 minutes in an aqueous bath containing, in each litre, 20 grams of sodium cyanate and 1 gram of a cation-active soap as a finishing agent.  The threads are then centrifuged to about 100 per cent. liquor retention and dried for 3 hours in a humid atmosphere at 70 DEG C.  The cyanate bath may contain about 5 grams per litre of cadmium chloride as a bactericide.  In other similar examples the hardening bath also contains aluminium sulphate and two successive hardening baths are used prior to the treatment with sodium cyanate. In another example lactic casein thread is esterified with methyl alcohol in the presence of sulphuric acid between two hardening treatments (as described in Specification 690,492) before treatment with sodium cyanate.  The number of processing steps of the present invention following the hardening treatment is less than that of the similar protein thread treatment disclosed in the parent Specification.  Specification 653,188, [Group IV(b)] also is referred to.

Title: Automatic yarn piecing and knotting method and apparatus for the  open-end spinning machine
IPC: D01H4/50
Filed: 1971-07-01
Abstract: 1357422 Piecing arrangement for break spinning machine HOWA KOGYO KK 1 July 1971 [4 July 1970 26 Dec 1970 (2) 29 Dec 1970 (3) 25 May 1971] 30815/71 Heading DID Yarn is pieced in a break spinning machine by feeding a first yarn end 404 into a delivery aperture of a break spinning rotor 203 to piece the yarn and withdrawing an upstream length of spun yarn from the rotor, retrieving a second yarn end from the take-up package 302 and leading parallel and close to the first yarn end, knotting the yarn ends and cutting off the excess and resuming normal spinning (Fig. 3 is the only Figure shown). As described, a travelling carriage containing the yarn piecing devices moves along a break spinning frame until it stops automatically where a yarn break has occured. Piecing yarn in rotor: Holding device 21 is moved upwards to place supplementary yarn end 404 below the delivery aperture of the rotor. An air stream directs the yarn end into the aperture, the end is released and rollers in supply device 1 feed the yarn end into the delivery aperture (Fig. 14, II). A yarn reserve in a deflected yarn path is released to allow the feed of the supplementary yarn into the rotor, (Fig. 14 III). The supply of separated fibres and take up rollers 206 are restarted to allow new yarn to be withdrawn from the rotor. Aligning yarn ends for knotting: A suction device S1 moves forward to the new yarn being spun, cuts this yarn, sucks up the ends and moves back to its original position. The second yarn end from the take-up package is retrieved by a swinging suction nozzle S2 and laid across guide wires (106, 108 Figs. 12, 13). As the knotter 75 moves forward, the guide wires move the second yarn end parallel to the first yarn end. The yarn ends are then knotted and the take-up package is lowered onto its drive roll. In an alternative embodiment, the broken end from the take up package is sucked up and fed to the holding device 21. This end is then led to the rotor, pieced and cut. The section of yarn containing the pieced portion is then cut off after knotting the yarn from the rotor with the yarn from the take up package.

Title: Improvements in or relating to the refinement of tin
IPC: C22B25/00
Filed: 1947-11-22
Abstract: 631,784. Refining metals; tin. NAAMLOOZE VENNOOTSCHAP BILLITON MAATSCHAPPIJ. Nov. 22, 1947, No. 31011. Convention date, Sept. 13. [Class 82(i)] A continuous refining process for the removal of lead from otherwise pure tin comprises continuously passing molten impure tin, in countercurrent flow downward through a column of lead removal medium consisting of stannous chloride and lead chloride, continuously regenerating the lead removal medium by distillation, alloying the lead, recovered from the said medium with a small quantity of tin and condensing the chloride vapours for re-use. The apparatus shown comprises a column 1 for receiving molten lead removal medium through conduit 5 which delivers the medium near the bottom of the column. Molten impure tin is fed into the column at 9 and passes through the medium in the form of droplets, purified tin overflowing from container 2 at 4. Depleted lead removal medium rises to the top of the column and is removed by outlets 3 to either of two retorts 10. The column of lead removal medium is maintained throughout at 260-300‹C. 'Lead removal medium flows into one of the retorts 10 which operates initially at a temperature of 630-650‹C. A small quantity of tin is introduced into the retort at the beginning of its operation, thus producing a stannous chloride vapour having a low lead chloride content. The retort temperature is increased to 700-800‹C. in the last stage of its operation. At this stage the flow of depleted lead removal medium is diverted to the second retort which is similarly operated. Chloride vapours are condensed in condensers 14 and pass to head tank 17. A storage tank 16 feeds fresh make-up stannous chloride into the circuit as required. From tank 17 is delivered the stannous chloride feed to the column 1. Electronic temperature control means are provided for maintaining the column, the retorts and the condensers at the required temperatures.
