Title: Improvements in or relating to the finishing of cellulose materials
IPC: D06M13/358
Filed: 1960-02-08
Abstract: The resistance to scouring of fibres, filaments, threads or fabrics of natural or regenerated cellulose is improved by treating them without previous alkali treatment with an aqueous dispersion of a triazin which contains at least two N = C-halogen groups, e.g. cyanuric chloride or bromide, at a pH of 7-10 for 1-30 minutes at a temperature of 15 DEG -60 DEG C. in the presence of an acid binding agent, drying them without washing and subjecting them to a heat treatment at a temperature above 100 DEG C.  The aqueous dispersion may contain a buffer, e.g. borax.  The cellulosic material may be rendered water-repellent by treating it with an amine compound, e.g. urea, melamine or an aliphatic amine such as heptylamine, oleylamine or stearyl amine, which may be present either in the same bath as the triazine or in a subsequent bath prior to drying.  The material treated with the triazine and amino compound may be treated with an aldehyde, e.g. formaldehyde or glyoxal, in the presence of a catalyst, e.g. ammonium biphosphate, prior to drying.  Alternatively a cyanuric halide may be reacted with an amino compound in an aqueous alkaline medium and the product which contains two halogen atoms then used to treat the cellulosic material.  Specifications 342, 167, 347, 926, 393, 914, 818, 492 and 818, 778 are referred to.

Title: Improvements in and relating to treatment of rosin and the products obtained thereby
IPC: C09F1/00
Filed: 1930-02-10
Abstract: <PICT:0354332/III/1> Wood or gum rosin is distilled under low pressures (below 20 mm. and preferably below 10 mm.) so as to avoid decomposition and the distillate is collected in fractions so as to obtain first the unsaponifiable ingredients referred to as resene and then the rosin acids referred to as abietic acid, with intermediate fractions containing varying proportions of these two ingredients. Temperature up to 260 DEG  C. are used.  The colour of the product may be lessened by passing a stream of air through the rosin during distillation.  Moisture and turpentine are removed from the rosin before treatment by a preliminary distillation under low pressure.  A still 11 heated directly or through a molten metal bath is fitted with a foam trap 15 from which a steam-jacketed vapour pipe 16 leads to two condensers 17 cooled by steam or hot water and fitted with barometric discharge legs 18 about 36 feet in length leading through traps 19 to condensate receivers 20.  The legs 18 are jacketed and heated by exhaust steam.  The condensers are connected through a trap 22 and pipe 21 to a vacuum pump.  Abietic acid free from resene is used for making resin soap.  In making ester gums, abietic acid containing varying proportions of resene is used so as to vary the nature of the products obtained.  Specifications 18235/14 and 298,214, [both in Class 32, Distilling &c.], and U.S.A. Specification 1,219,413 are referred to.ALSO:Ester gums are prepared from the products obtained by distilling rosin under low pressure so as to avoid decomposition and collecting the distillate in fractions containing varying proportions of the unsaponifiable ingredients and of the rosin acids.

Title: Percussion fuze, more particularly for small calibre ammunition
IPC: F42C15/22
Filed: 1938-02-16
Abstract: 503,697. Projectile fuzes. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST, BRNO. Feb. 16, 1938, No. 4870. Convention date, March 17. 1937. [Class 9 (i)] Relates to a direct- - . - . action percussion fuze, particularly for small calibre ammunition, in which the striker is retained in the inoperative position by means of elements that are released by centrifugal force during, flight. According to the invention, the striker is normally held in the inoperative position by supporting members arranged between and located by a pair of conical seatings provided on parts that are prevented from relative movement by a plurality of locking elements, said elements being movable under the action of centrifugal force to free said parts for relative movement and thereby enable the supporting members under the action of centrifugal force, acting on them also, to move outwardly from between the conical seatings so as to release the striker and render it operative.. As shown, the body 1 of the projectile is formed with an axial bore in which is screwed a sleeve 2 carrying the detonator charge 3. Above the sleeve 2 and separated from it by a thin metal disc 4, is arranged a guide-sleeve 5 which is also screwed into the body 1. The sleeve 5, which is,provided with an axial bore 6 for the striker 10, is also formed on its upper surface with a conical seating 7 adapted to support the centrifugal balls 9. The striker is formed with a headpiece 11 which is located in an off-set bore in a ring 15, the underneath surface of this headpiece forming with the under surface of the ring 15 an uninterrupted conical seating 12, 16 which supports the striker on the balls 9. A membrane 19 is arranged in the bore of ring 15 to protect the striker. The ring 15 is provided on its lower circumference with resilient projections 17 which terminate in relatively large feet 18 adapted to engage in recesses 8 in the sleeve 5. In operation, after discharge of the projectile, the centrifugal force of the feet 18 overcomes the resistance of the projections 17 and the feet are disengaged from the recesses 8, thereby freeing the ring 15. The balls 9, which are also freed, are urged outwardly by the centrifugal force and consequently exert a pressure on the conical seating 12, 16 of the headpiece 11 and ring 15. The weight of the balls is so chosen that, after discharge of the projectile from the gun barrel, the centrifugal force is able to overcome the resistance of the air pressure acting on the outer surface of ring 15 and on the membrane 19 and to displace the striker, together with the ring, in the direction of travel of the projectile. The passage between the sleeve 5 and ring 15 is thus freed and the balls 9 drop out into recesses 20 in the body 1 and the striker is armed. If desired, the projections 17 may be attached directly to the striker and the recesses 8 may be formed directly in the body 1 or in any other part, rigidly connected therewith.

[Classes 72 and 82 (i)] An alpha-beta brass also contains 0.3-2.5 per cent of magnesium with or without one or more of the elements nickel, manganese, iron, lead, tin, aluminium and silicon, the total amount of such elements not exceeding 3 per cent, the aluminium content not exceeding 2 per cent, the silicon 1 per cent, lead 2 per cent and iron 1 per cent when present. In examples : where 1 per cent of nickel is present the copper content is 54.8-61.6, for 1 of manganese the copper 55.7-62.6, for 1 of tin the copper 56.8-63.6, for 1 of aluminium the copper 59.0-66.1 and for 1 of silicon the copper 61.1-68.6. For an alpha-beta brass containing 56 per cent of copper the magnesium content is 0.9-2.5 per cent, and for brass containing 60 of copper the magnesium is 0.5-2.5, a particular example containing 0.9-1.2 per cent of magnesium for a copper content of 59-61. The alloys are heated-treated by quenching from a temperature, e.g. 700-850‹ C., above that at which the alloy becomes substantially " beta " in structure and which may be produced by hot working or the initial heating, with or without re-heating to 200- 500‹ C. for 30 minutes to 5 hours and allowing to cool. The alloys may be hot worked, e.g. rolled, forged or extruded, after casting and. before being heat-treated. If the alloys are subjected to cold deformation either after annealing (slowly cooling from 650‹ C.) or fully heat treated when the final stage was carried out at 400-450‹ C., the hardening effect of the cold working may be removed by further treatment at 400-455‹ C.
