  • Patent number: 5426957
    Abstract: A method of knitting single knit fabrics on a circular knitting machine such that the fabric has improved elasticity, soft hand and drapeability and including controlling two types of needles arranged alternately in the cylinder and sinkers arranged in the sinker dial through four processes in which alternate needles are raised to the knitting level in the first process and intervening needles are raised to the tucking level and an old loop has cleared the latch on each needle and a previously fed yarn is held in the hook of each intervening needle, a first ground yarn is fed to the alternate and intervening needles and the needles are lowered to a high welt level for the alternate needles so that the old loop is not knocked over and a low welt level for the intervening needles so that the old loop is knocked over and a new double yarn stitch loop is formed. The levels to which the alternate and intervening needles are raised are reversed in the third process.

  • Patent number: 3930830
    Abstract: A method for forming a glass article of a devitrifiable glass having an optimum working temperature in the vicinity of its liquidus temperature, wherein the temperature of the molten glass is, during the molding operation, maintained at considerably higher temperature than both the optimum working temperature and the liquidus temperature, the molded article is passed through water or a layer of wet granular materials floating in water before the temperature of the molded article drops down to the liquidus temperature and before the molded article is deformed to rapidly cool the article to a temperature below the devitrifying temperature.
