Filed: 1926-11-19
Abstract: 278,543. Morton Sundour Fabrics, Ltd., Morton, J., and Webster, J. B. Nov. 19, 1926. Weft deflecting for slackening.-The weft W, after insertion in the shed of a carpet loom &c., is acted upon by vertically-moving fingers 32 and angularly-moving or pulling fingers 28 whereby it is slackened and undulated, after which the extra length of weft thus obtained is beaten up. The vertical fingers 32 are carried by a rod 34- from levers 35 furnished with rollers 37 engaging cam slots 38 in stationary brackets 20, so that the levers 35 are rocked as the lay moves, the fingers 32 being withdrawn downwards through their guides 31 just before the beat up. The pulling-fingers 28 are carried between the vertical fingers 32 by collars 24, which are oscillated on a shaft 25 by cranks 23 and adjustable rods 21 adjustably connected to spring-controlled levers 15 acted upon by respective cams 13 on a shaft 6 driven from the picking shaft 5. The cams are so arranged that the pulling-fingers 28 are rocked upwards in recesses 29 in the lay in sequence from one side of the loom to the other corresponding to the direction of movement of the shuttle, so that the inserted weft engaged by the vertical fingers 32 is gradually moved into wave form. The pulling-fingers 28 are all withdrawn in unison into their recesses. The lumps 30 of the cams 13 are made separate from the bodies and are removably fitted in slots therein and secured by screws. To vary the amplitude of the waves formed in the weft to suit different fabrics &c. the shaft 25 is adjusted in its bearings towards or away from the front of the batten. The vibrations of the fingers 28 are damped by a rod furnished with a rubber sleeve 40. In a modification, the vertical fingers are actuated by lever mechanism from cams on the shaft 6. A modification is also described wherein the pulling- fingers 28 are actuated by two cams on the shaft 6.

Title: Improvements in curing polyhydric alcohol-polycarboxylic acid condensation polymer compositions
IPC: C08L67/00
Filed: 1947-11-03
Abstract: A fast-curing composition comprises a major proportion, e.g 70-98 per cent by weight of polyhydric alcohol-polycarboxylic acid condensation polymer at the stage in which it has visible cold flow, a minor proportion, e.g. 2-30 per cent by weight of an alkylated urea- or melamine-aldehyde condensation polymer and intimately dispersed therein, 0.2-5.0 per cent by weight of pure colloidal carbon black with particle size hetween 25 and 100 millimicrons and a pH of 7 to 10.  In the higher ranges of carbon black proportion, the excess over that required for curing acts as a filler.  A vinyl polymer, e.g. polyvinyl butyral may be included in the composition to produce an adhesive cement.  Pigments, e.g. TiO2 or ZnO may be added to mask the colour of the carbon black.  Preferred polyhydric alcohol-polybasic acid condensates have an acid number below 50 and contain 10-35 per cent of dihydric alcohol of 2-6 carbon atoms, e.g. ethylene, propylene, diethylene or triethylene glycol; 10-55 per cent of saturated aliphatic dibasic acid, e.g. adipic, pimelic, suberic, azelaic, sebacic, or dimethylsuccinic acid, or of a mixture of acids such as roleic acid.  There may also be present 10-20 per cent of short chain monofunctional acid or alcohol, or 10-55 per cent of cyclic dibasic acid, e.g. phthalic; 3,6 - endomethylene - D 4 - tetrahydrophthalic anhydride or Petrex acid.  Other components may be glycerol, trimethylolpropane, butanetriol-1,2,3, or pentaglycerol; or acids, e.g. lauric, myristic, palmitic, stearic, ricinoleic or their glycerides.  The urea of melamine aldehyde condensation product is preferably alkylated with a saturated alcohol having 3-10 carbon atoms.  In example 1 a condensation product of glycerine, diethylene glycol and phthalic acid dissolved in xylene is mixed with carbon black and with a solution in butanol and xylene of a butylated urea-formaldehyde condensation product, an acid catalyst for the butylated urea-formaldehyde, a curing catalyst which is benzoyl peroxide or calcium sulphate, and xylene.  The composition was used to impregnate Kraft paper (see Group VIII), and was dried and cured by infra-red radiation for a short time.  The product remained flexible, but had improved physical strength.  A number of similar examples are given, different resins or combinations of resins being used and changes also being made to the solvents, fillers and catalyst employed.
