    摘要: This invention provides an overload protection device wherein a dangerous situation warning is given to workers in architectural construction when a load value imposed on a temporary column reaches a preset value. The device comprises a load pedestal above and a base pedestal below, a load detecting equipment which detects the load value on the load pedestal after converting the load value into a hydraulic pressure value, a pressure detecting equipment which operates when the pressure reaches the preset value, and a notice equipment which informs workers that the load value imposed on the temporary column has reached the preset value.

    摘要: The present invention provides elastic polyurethane yarns which possess excellent elongation, recoverability, heat resistance and chemical resistance, as well as a method of manufacturing the same. The elastic polyurethane yarns comprise a polyurethane being composed mainly of a polymeric diol and a diisocyanate, and contains through incorporation a compound having within the molecule a phosphorus-nitrogen interatomic bond(s). The process can produce the elastic polyurethane yarns by adding to a solution of the polyurethane a compound having within the molecule a phosphorus-nitrogen interatomic bond(s), followed by spinning.

    摘要: The present invention relates to a process for producing an alkyleneoxide adduct, including the steps of reacting an aliphatic alcohol containing a hydrocarbon group having 6 to 22 carbon atoms with an alkyleneoxide in the presence of a catalyst to obtain a reaction product containing an alkyleneoxide adduct; and subjecting the reaction product successively to acid treatment and reduction treatment, and an alkyleneoxide adduct having a carbonyl value of 5 μmol/g or less. The alkyleneoxide adduct is useful as a raw material of various anionic surfactants, and the anionic surfactants derived from the alkyleneoxide adduct are free from undesirable coloration.
