Title: Process of improving resins
IPC: C08G2/00
Filed: 1923-07-31
Abstract: The Specification as open to inspection under Sect. 91 (3) (a) describes melting colophony with castor oil to obtain an agglutinant which may be used as bird-lime.  This subject-matter does not appear in the Specification as accepted.ALSO:Artificial resins obtained by polymerization or condensation of aldehydes alone or with other substances, excluding those obtained by condensation of phenols with aldehydes and of formaldehyde with urea, are improved by incorporation in the resin of one or more compounds containing a hydroxyl or a carbonyl group or their derivatives or mixtures of them with other substances. The process is promoted by the presence of a solvent or by working under pressure.  The resins may be hardened before or after treatment in known manner, for example by thermal treatment or by esterification.  Examples show the incorporation by melting in polymerized acetaldehyde resins of ricinoleic acid, of castor oil and aluminium oxide, of castor oil alone and of mesityl oxide, and in polymerized crotonaldehyde resins of phenol and of castor oil.  Other examples of suitable additions are dioxystearic acid, salicylic acid and phorone.  The elasticity solubility and fusibility of the resins are improved.  Specifications 26928/10 and 182,459 are referred to.  The Specification, as open to inspection under Sect. 91 (3) (a) describes also the improvement by the method described above of artificial resins in general and contains also the following examples-melting Alberto (a phenol-aldehyde resin) with castor oil, and coumarone resin with dioxystearic acid.  Dioxyabietic acid is also referred to as a suitable addition.  This subject-matter does not appear in the Specification as accepted.

Filed: 1972-05-04
Abstract: 1340281 Texturized thread; turbulent fluid jet AEROTEX SA 4 May 1972 [4 May 1971] 20763/72 Headings D1F and D1W A method of manufacturing a texturised thread comprises continuously winding two bundles of filaments B, C around a central bundle of filaments A, one in the S-direction, and the other in the Z-direction at a rate of 50-200, preferably 80-110 turns per metre of the group of filaments thus obtained, subjecting the group of filaments D thus obtained to the action of a fluid under pressure and in turbulence that is channelled in the direction of movement of the group of filaments D, and during the action of the fluid, the group of filaments is not subjected to drawing tension. Referring to Figure 1, a bundle of filaments A is taken from supply bobbin A and fed through the bore of a rotating bobbin 5 from which a bundle of filaments B is taken to wind about the bundle A. The composite bundle A, B is fed through the bore of an oppositely rotating bobbin 6 from which a bundle of filaments C is taken to wind about the composite bundle to form bundle D. The bundle D passes over feed roll 7 and guide 8 to texturising apparatus 9. The texturised thread E is taken up on roll 12. The speed of take-up is reduced by 10-20% relative to speed of roll 7 to allow the filaments freedom to intermingle in the apparatus 9. Some of the filaments of the thread E possess superficial loops. The composition of the three bundles may be the same or different in respect of the number of filaments and/or the material of the filaments. The filaments may be synthetic, natural, organic, inorganic or mineral; they are preferably chosen from the group of polyamides, polyacrylics, polyesters, chlorofibres, elastomers, glass or cellulose filaments. The texturising apparatus 9 comprises two aligned and associated elements 15, 17 which define between them a chamber 18 for fluid under pressure. The first element 15 has an axial channel 19 for conveying a group of filaments, and the second element 17 has an exit channel 20 common to the filaments and the fluid. Adjacent the inlet of the exit channel 20, the element 17 is provided with an annular wall 22 which is perpendicular to the channel 19. Conduits 23 are provided in element 15 for conveying pressurised fluid from inlet pipe 10 to the chamber 18, the conduits 23 discharging opposite the wall 22 to create a turbulent fluid zone. The channel 20 flares from the inlet to the outlet to provide freedom for expansion in the group of filaments. The fluid is preferably supplied under a pressure of 3-6 kg/cm<SP>2</SP>, and the dwell time for the filaments in the fluid is 0.1-0.2 seconds. Suitable dimensions are given for the channels 19 and 20.
