Title: Threads of thermoplastic material and their manufacture
Inventor: LACY GEORGE HAYES
IPC: D01D5/42
Filed: 1956-09-12
Abstract: An artificial thread having along its length areas upon which a pigment or dye has been deposited alternating with areas upon which no pigment or dye has been deposited is produced by depositing a pigment or dye (or a composition containing a pigment or dye) on predetermined areas of the surface of a length of film of organic synthetic thermoplastic material and then slitting the film longitudinally to form a plurality of threads, each in the form of a narrow <PICT:0821149/IV (a)/1> <PICT:0821149/IV (a)/2> strip, the disposition and shape of the pigmented areas of the film with respect to the direction of slitting being such that pigmented and unpigmented areas alternate along the threads.  The film material may be cellulose acetate butyrate, cellulose acetate propionate, cellulose acetate or polyethylene terephthalate.  The web of film may be printed with transversely extending bands of colour or patterns having sharply defined boundaries.  The web may include several sheets laminated together prior to slitting and pigment applied to one or all of the sheets is preferably included within the laminate and not on its outer surfaces.  The film may be laminated with a foil of metal, such as aluminium, or may have metal deposited on it from metal vapour under high vacuum.  The printing of the patterns or bands of colour on the web may be effected before or after the lamination of the web with metal foil or deposition of metal on the web from vapour.  As shown in Fig. 1, webs 10, 11 of transparent film from feed rolls 12, 13 are laminated by the rolls 17 with a metal foil 15 from the feed roll 16.  The webs 10, 11 are printed by the printing rolls 14 with a striped pattern in which clear strips 18 alternate with coloured portions 19 and the lamination is taken up on the roll 22.  In the laminated web the clear stripes 18 reveal the metallic surface of the foil 15.  As shown in Fig. 2, the laminated web is then slit into numerous threads 20 by the knives 21, the threads being then collected on spools (not shown).  The threads may be employed in woven fabric, either as a warp or as a filler, and may be woven twisted or flat.  The clear stripes across the web may be non-parallel, so that each thread cut from the web has a pattern differing from that of the other threads.  The printing on the web may have a form other than transverse stripes, e.g. a box design.

Title: Improvements in and relating to the manufacture of paints, enamels or the like and drying oils therefor
IPC: C09D17/00
Filed: 1931-10-08
Abstract: Drying oils for paints, enamels, &c. are purified by prolonged contact with finely-divided basic zinc compounds such as the oxide, hydroxide, carbonate, or a basic salt, in the absence of water, and without heating, the residue being separated by filtering or centri fuging.  In treating oils having a low content of acid, the zinc compounds are added in the form of a paste with an oil of high acid content in order to avoid settling, and in this case the residue may be used for cleaning further batches of oil.  The residue, added in small quantities to any paint or enamel, prevents settling of the pigments.  Paints, which have a high percentage of pigment, and do not settle or thicken, may be prepared from an oil partially cleaned by conducting the treatment with zinc compounds so as to leave a certain amount of free acid; or by mixing the pigments to a paste with a drying oil having a content of free acid below 0,5 per cent, treating the paste in a high-speed mixing machine or allowing to stand, and diluting the paste with any drying oil, with varnish, or with a thinner.
