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:
This specification discloses skis having the following characteristics: (1) an upwardly curved front tip, (2) an uncurved sliding surface, (3) a steering string attached to the curved front tip, (4) a boot heel binding near the tail end of the ski plate so as to place the center of the body weight near the tail end of the ski, (5) overall length which is remarkably shorter than that of conventional skis, and (6) gradually increasing thickness from the front tip to the tail end.
Abstract:
THIS INVENTION RELATES TO VERY THIN POLYAMIDE FILMS HAVING HIGH PURITY AND TRANSPARENCY, HIGH TENSILE STRENGTH, AND OTHER IMPROVED PROPERTIES.
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.
