Abstract: The chain is formed of a series of links of general C-shape with the link diameter greater than the width of the gap at the ends of each to prevent disengagement therethrough, and a sound absorbing continuous length of sash cord of a diameter substantially equal to the gap width is combined with the chain length by insertion through the link gaps of such cord successively in alternating fashion along the length of the chain.
Abstract: Toy elements are connected with sprocket chain elements by mutually cooperating connecting means, in form of undercut keys and of correspondingly shaped, undercut grooves. Each toy element has at least one of said connecting means, while at least some of said chain elements have the cooperating connecting means. The elements of the chain detachably connect with each other. The toy elements may be tread members or bucket members, and the latter may be connectable to the sprocket chain in two different positions.
Abstract: A binder of a plastic material is disclosed which comprises a slender shaft with a suitable thickness and a plurality of disc-shaped flanges disposed at fixed intervals in the longitudinal direction of the said shaft. Articles given to be fastened are bundled or bound by winding this binder around the articles, crossing the loose remaining ends of the binder each other at right angles and pressing the corresponding pairs of adjacent flanges into entanglement.
Abstract: A chain cable in which each link is characterised by being formed from a bar .[.bent into a.]. .Iadd.of .Iaddend.U-shape bridged at the extremities by a cylindrical pin of length substantially equal to its diameter which mates under load with the U-shaped bar of a next adjacent link to give a substantial bearing area between links so that bearing failure may be eliminated as a first-occurring manner of failure of the chain cable when it is subjected to a tensile load.
