Filed: 1973-09-19
Abstract: 1443321 Yarn packages; winding TEIJIN Ltd 19 Sept 1973 44011/73 Heading B8M [Also in Divisions D1-D2] A package of crimped thermoplastic synthetic fibre yarn has a winding hardness (measured as described) of from 80-95 degrees and a moisture content such that the moisture content of the yarn at the inner portion (defined) of the package is less than or equal to the equilibrium moisture content of the yarn at a relative humidity of 60%. The yarn is preferably a polyamide yarn. The yarn may be produced by heat-setting a false twist yarn and winding the yarn on a package such that when the yarn is unwound, the force acting on the yarn at the unwinding point is opposite to the torque acting on the yarn as a result of false twist. The package may be wrapped in a moisture-impervious material, e.g. fuse-sealed thermoplastic polymeric material. The package is produced by winding the yarn at a tension of from 0À25-0À7 gm./denier in an atmosphere of relative humidity at most 60%. The yarn is preferably knitted or woven in an atmosphere of RH at least 60%.

Foodstuffs exemplified by coffee, butter, eggs, fruit, vegetables, sardines, salami and sliced salted bacon, are preserved against chemical deterioration by storing them at ambient temperature in a protective atmosphere maintained at a pressure not exceeding about 1 atmosphere and consisting of, or comprising, nitrous oxide. The atmosphere may consist of nitrous oxide, one or more inert gases, and/or oxygen; the partial pressure of the oxygen in the atmosphere should not exceed 20% of the partial pressure of the nitrous oxide. The treatment with nitrous oxide may be used in combination with other sterilizing treatments e.g. irradiation with radio-active isotopes. The nitrous oxide-containing atmosphere may be produced by (i) first evacuating air from the foodstuffs contained in a receptacle and then feeding in nitrous oxide to the required pressure, (ii) successive washing operations with inert gases, then exhausting such inert gases and feeding in nitrous oxide to the required pressure, or (iii) successive washing operations with nitrous oxide until the required partial pressure of nitrous oxide is reached. The foodstuffs may be stored under the nitrous oxide atmosphere in containers made of metal, plastic, or paper impregnated with synthetic solutions, and in warehouses or silos.
