    Abstract: A composition comprising an aromatic co-polyester and poly(ethylene oxybenzoate), in which A. THE AROMATIC CO-POLYESTER IS A RESINOUS PRODUCT REPRESENTED BY THE FORMULA:
    WHEREIN X is -O-, -S-, -SO-, -SO2-, an alkylene group or an alkylidene group; R1, R2, R3, R4, R''1, R''2, R''3 and R''4, which may be the same or different, each is a hydrogen atom, a chlorine atom, a bromine atom or a hydrocarbon group having 1 to 6 carbon atoms and n is a positive integer which provides a resinous product; B. THE POLY(ETHYLENE OXYBENZOATE) IS PRESENT IN AN AMOUNT OF FROM 0.1 TO 50 WEIGHT % BASED ON THE SUM OF THE WEIGHT OF THE AROMATIC CO-POLYESTER AND THE POLY(ETHYLENE OXYBENZOATE); AND C. THE

    MOIETY IN THE ABOVE FORMULA IS A TEREPHTHALIC ACID UNIT OR AN ISOPHTHALIC ACID UNIT, AND IS PRESENT IN THE AROMATIC COPOLYESTER AT A MOLAR RATIO OF 9:1 TO 1:9, RESPECTIVELY, USEFUL AS A COMPOSITION FOR PRODUCING MOLDED ARTICLES HAVING IMPROVED HYDROLYSIS, CRACKING AND CRAZING RESISTANCE.

    Abstract: A fishing gill net made of synthetic fiber yarns whose legs or parts between the knots constituting the meshes thereof, each in parallel or which are specifically loosely entangled but untwisted with one another. In water, depending on these constructions of the filaments composing legs, respective filaments separate from each other and form small meshes between the two knots in addition to ordinary ground meshes between the multiple legs.

    Abstract: The device of the present invention is used for checking whether each of running yarns is twisted at the standard turns per minute. This device comprises a driving shaft, a motor provided with a variable speed means and a yarn contact means. The driving shaft is rotated at a rotating speed corresponding to the standard turns per minute, at which each of running yarns should be twisted. The yarn contact means is imparted a torque from the shaft and running yarn, which is brought in contact with it. The shaft and the yarn contact means carry marks which can be viewed with a stroboscope to determine whether the shaft and contact means are rotating at the same speed.
