Title: Artificial filamentary material
Inventor: JR STEWART WELLS MORSE
IPC: D01F2/28
Filed: 1959-05-13
Abstract: The process of the parent Specification (wherein a spinning solution of cellulose triacetate in methylene chloride, or in a solvent containing methylene chloride as the major component, is extruded in filamentary form into a coagulating liquid comprising methylene chloride and an aliphatic alcohol containing 1-3 carbon atoms and the filaments are stretched during their passage through the coagulating liquid, the coagulating liquid containing more than 25% of methylene chloride and the conditions being predetermined to yield a product of a tenacity of at least 1,8 grams per denier coupled with an extensibility of more than 18%) is modified in that, before drying the filaments, they are treated with an organic liquid, other than isopropanol, in which methylene chloride is soluble and the cellulose triacetate insoluble.  The liquid preferably boils below 150 DEG C. and may be an aliphatic hydrocarbon or a mixture of such hydrocarbons, a cycloaliphatic hydrocarbon, e.g. cyclohexane, an aromatic hydrocarbon, particularly xylene, or an ether, e.g. isopropyl ether.  The liquid is preferably used at 20 DEG -40 DEG C. In an example, a 22% by weight solution of cellulose triacetate in a mixture of 91 parts by weight of methylene chloride and 9 parts by weight of methanol is spun upwardly through a 40 hole spinning jet through 1,7 metres of a coagulating liquid consisting of 42,2/57,8 by weight methylene chloride/methanol maintained at 35 DEG C. and circulated upwardly through a vertical column.  After emerging from the coagulating liquid, the yarn is passed to a driven feed roll and thence through a horizontal bath of xylene at room temperature to a take-up bobbin rotated at a peripheral speed the same as or somewhat lower than that of the feed roll.  The yarn is finally dried first in air and then at 50 DEG C. under subatmospheric pressure.  The liquid used for treating the filaments may be methanol or a mixture of methylene chloride and methanol in which the concentration of methanol is at least 5% lower than its concentration in the coagulating liquid.  Said treating liquid and the coagulating liquid may pass through a vessel, e.g. a vertical spinning column, containing the liquids in the same direction and the treating liquid, e.g. methanol, may be introduced into the column at a point along the path followed upwardly by the filaments so as to form the treatment liquid by blending with the coagulating liquid.  The washing of the filaments before drying, according to the invention, prevents the filaments from coalescing when the filaments are dried in contact with one another.  Specification 881,856 also is referred to.

Abstract: 605,259. Impedance networks. TUSTIN, A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 5, 1944, No. 16979. [Class 40 (viii)] [Also in Group XXXVIII] A phase-advancing network in a control system, e.g. for a gun, sight or searchlight, comprises a series-resonant circuit tapped in such a way that the amplitude of the output is relatively small at frequencies above the working range. The invention is applicable for checking hunting, providing for pre-retardation, and compensating the personal time-lag of a manual operator. The voltage V1 derived from the controlling means is applied at a, b, Fig. 1, and the voltage Vo applied through leads c, d to the controlled equipment comprises the vector difference between a fraction k1, v1 of the input voltage and the voltage across the lower part of the condenser C. The vector diagram, Fig. 4 (not shown) indicates that while the phase advance increases rapidly with frequency at the lower frequencies, the output amplitude approaches a finite value k1, v1 at high frequencies, in contradistinction from systems in which the output is proportional to the rate of change of the input. A damping resistance R is included to prevent undue attenuation at low frequencies. In a modification, Fig. 2 (not shown), the inphase component comprises the whole of the input voltage, so that k1 =1, and the condensers are shunted by a leak resistance to prevent ambiquity at zero frequency. Figs. 6, 7 (not shown) are diagrams for use in selecting values of R, L and C to suit given conditions.
