    摘要: Organopolysiloxanes having SiC-bonded oxyalkylene units and Si-bonded hydroxyl groups, in which an average of at least 15 mol percent of the siloxane units contain only one SiC-bonded monovalent organic radical and the silicon valences which are not satisfied by the SiC-bonded monovalent organic radical are satisfied by siloxane oxygen atoms or oxygen atoms of hydroxyl groups. These organopolysiloxanes are preferably prepared by reacting triorganosiloxy end-blocked organopolysiloxanes consisting of diorganosiloxane units, in which at least part of these units contain SiC-bonded oxyalkylene units and, if appropriate, organohydrogensiloxane units or organohydroxyl siloxane units or organoalkoxysiloxane units of mixtures of at least two such monoorganosiloxy units with water in the presence of an acid or base or, and subsequently with a silane or simultaneously with water and a silane in which the silane contains one SiC-bonded monovalent organic radical, or partially hydrolyzed products of the silane. The new organopolysiloxanes are applied to textile fibers to impart hydrophilic properties thereto.

    摘要: A wrench having a handle with an actuating lever arm pivoted for operation to rotate a nut engaging ring geometrically configured to accept a nut or bolt head. The nut engaging ring includes two tappets extending in the plane of rotation of the lever arm. A torque applied to the lever arm engages these tappets and thereby causes the nut engaging ring to rotate with increased force.
