Abstract: A method and apparatus for measuring the remaining charge of a galvanic cell effects the measurement of the remaining charge by superimposing an AC voltage or current on DC voltage or current issuing from the cell to produce a higher harmonic current or voltage, determining the value corresponding to a higher harmonic component of n'th order from the higher harmonic current or voltage, and comparing the value thus measured of the cell under test with that measured previously in the same manner of a reference galvanic cell. Since the corresponding value of the higher harmonic current or voltage of n'th order varies notably with the decrease in the remaining charge of the galvanic cell, the comparison of the found corresponding value with the reference characteristic is effected with ease and the measurement can be carried out accurately and simply.

Abstract: A method for the formation of a three-dimensional woven fabric comprises causing arms of carriers disposed around one component yarns out of three mutually perpendicular component yarns and having the other two component yarns separately held thereon to be rotated, opposing carrier arms of adjacent carriers to each other thereby effecting transfer of yarns, and successively effecting said transfer of yarns to carrier arms of the subsequent carriers thereby enabling the two component yarns to be displaced and zigzagged relative to the remaining one component yarn. An apparatus for effecting the aforementioned method essentially comprises a multiplicity of carriers arrayed longitudinally and laterally on a carrier holding plate and means for imparting necessary movements to the carriers. The three-dimensional woven fabric can be formed in a desired shape or yarn arrangement by suitably varying the pattern of arrangement of the two component yarns.
