Title: Process for the modification of flat-shaped textile articles
IPC: D06C7/02
Filed: 1975-01-06
Abstract: 1496689 Forming patterns on textile articles PLAUENER GARDINE VEB 6 Jan 1975 [7 Jan 1974] 413/75 Headings C3P and C3G [Also in Division B2] A process for forming a pattern on a surface of a flat textile article comprises (a) applying a paste containing a monomer, prepolymer or polymer in the form of the desired pattern to the surface of the article, (b) evenly irradiating the whole surface of the article with high energy radiation, and (c) deactivating the irradiated surface. Step (a) may be performed before or after step (b). The radiation is suitably accelerated electron beams and before step (c) is effected the article may be moistened or exposed to moist air. Step (c) is suitably effected with the aid of hot air or long-wave radiation. The monomer or (pre)polymer paste may contain a thickening agent, colouring or tinting agent, a hygroscopic substance, a grafting accelerator, or a polymerization inhibitor. In the examples the articles are formed from polyamide, polyester or polypropylene and are treated with an aqueous paste containing acrylamide and/or an aqueous paste containing acrylic acid.
Patent GB-735358-A (GB)
Title: Process for sizing nylon yarn
IPC: D06M15/263
Filed: 1953-01-07
Abstract: Nylon yarn is sized with the ammonium salt of a hydrolysed copolymer of vinyl acetate and crotonic acid wherein, before hydrolysis, the mol. ratio of vinyl acetate to crotonic acid is between 5.5 and 19 to 1, and the degree of hydrolysis is at least 15 per cent.  The salt decomposes on contact with the atmosphere or on heating to form the free acid copolymer on the yarn. Examples describe the use of solutions in 1 per cent aqueous ammonia of (3) 50 per cent and 70 per cent hydrolysed copolymers, and (4) a 15 per cent hydrolysed copolymer containing 85 per cent vinyl acetate and 15 per cent crotonic acid.ALSO:Nylon yarn is impregnated with a hydrolysed copolymer of vinyl acetate and crotonic acid wherein, before hydrolysis, the mol. ratio of vinyl acetate to crotonic acid is between 5.5 and 19 to 1 and the degree of hydrolysis is at least 15 per cent, by treating the yarn with the ammonium salt of the hydrolysed copolymer, which decomposes on contact with the atmosphere or on heating to form the free acid copolymer.  Hydrolysis is preferably effected by heating the copolymer in a large excess of aqueous ammonia under autogenous pressure at 80 DEG  to 90 DEG  C. until 40 per cent of the acetate groups have been hydrolysed, cooling and allowing to stand, whereby lactone formation and cross-linking are avoided. The copolymer may be prepared by refluxing crotonic acid and vinyl acetate in the presence of benzoyl peroxide, gradually adding to the viscous solution benzoyl peroxide in a butanol-xylene mixture, continuing to reflux and finally adding more butanol and xylene. The solvent is removed by vacuum distillation and the copolymer dissolved in aqueous ammonia.

Filed: 1957-01-08
Abstract: <PICT:0832248/III/1> <PICT:0832248/III/2> <PICT:0832248/III/3> <PICT:0832248/III/4> The temperature of a silicon monocrystal i reduced from above 400 DEG  to below 400 DEG  C. at a rate not exceeding 20 DEG  C. per minute.  The minority carrier lifetime is thereby maintained or restored.  A particularly beneficial effect on lifetime is obtained if the body is held at a suitable annealing temperature for a long period before the temperature is reduced to 400 DEG  C.  In one embodiment a pulled monocrystal containing a junction between 30 ohm. cm. P-type and 0.3 ohm cm. N-type silicon is cooled at a rate of 20 DEG  C. per minute from 1000-1200 DEG  C. to 400 DEG  C. in two stages with intermediate cooling to an annealing temperature in the range 700-900 DEG  C. which is maintained for a period of between 1/2 and 4 hours.  In another embodiment silicon with high lifetime is produced by a process of seed crystal withdrawal in which the rate of cooling of the crystal as it leaves the melt is controlled by means of heaters disposed along its length. The maximum rate of cooling is again 20 DEG  C./minute and the cooling step may include a soaking at a suitable annealing temperature.  Fig. 1 illustrates graphically the lifetimes in silicon monocrystals after cooling from various temperature at rates ranging from that associated with oil quenching (10,000 DEG  C./second), curve A, to 0.5 DEG  C./minute, curve E.  Figs. 2, 3 and 4 show the fraction of the original lifetime which may be recovered after quenching from temperatures of 450 DEG , 580 DEG  and 710 DEG  C. respectively by periods of annealing of varying duration at a number of temperatures followed by cooling to 400 DEG  C. at a rate of less than 20 DEG  C./minute.  Prior to the heat treatment the bodies are thoroughly cleansed by etching first in a mixture of nitric and hydrofluoric acids and then in hot nitric acid.  The heat treatment is carried out in vacuo or in a flow of helium, hydrogen or nitrogen by mounting the bodies on a tantalum tray in a scrupulously cleansed silica tube. Specification 818,419 is referred to.

Abstract: 635,870. Automatic control systems for aircraft. SPERRY GYROSCOPE CO., Inc. Jan. 9, 1948, No. 741. Convention date, Jan. 9, 1947. [Class 38 (iv)] The altitude of a pressurized-cabin aircraft is normally maintained at a datum level by atmospheric pressure responsive means which act on the elevator ; should the cabin pressure fall, for any reason, the elevators are operated to cause the aircraft to fly at a predetermined lower level. As shown in the gyro-vertical stabilized auto-pilot, Fig. 1, the bellows 48 is sensitive to the ambient air pressure and positions the elevator 25 through the pick-off 43, amplifier 21 and motor 24 to maintain the craft at an upper predetermined level. Deviation of the craft from this level is accompanied by contraction or expansion of the bellows and the armature 90 as described in U.S.A. Specification 2,419,979, is moved relative to the winding 91, the output from which corresponds in phase-sense and amplitude with altitude deviation. Follow-up is effected by the application of the pick-up signal to amplifier 81, which supplies the motor 84, the rotation of which effects translation of the casing 49 supporting the bellows 48. The bellows 130 is sensitive to cabin pressure and upon reduction of cabin pressure, e.g. due to the development of a leak, expansion occurs, the contacts 125 close and relay 104 is energized and the motor 84 moves 49 along shaft 60 and thereby rotates 90 to produce a signal in 91 which deflects the elevator 25 and reduces the craft altitude until the rotation of gearing 69, 70, 73, 73<1>, 100, 101 causes opening of contacts 115 and motor 84 stops. The follow-up then levels off the craft. Specification 603,221 is referred to.
