Abstract:
An improved starter pull cord for an internal combustion engine having significantly increased stiffness, resistance to wear, and strength, the starter pull cord being comprised of rope having high modulus fibers selected from the group consisting of liquid crystal polymer (LCP), aramid, and high-modulus polyethylene (HMPE). The higher stiffness of the high modulus starter pull cords of the present invention translates to greater impetus during the act of pull starting the engine, which is apt to start more quickly than with starter pull cords of the prior art. The increased strength of the high modulus starter pull cords translates to fewer breakages over the lifetime of an engine and therefore increased reliability.
Abstract:
A bead wire has a composition of Mn: 5 - 35 at% and Al: 5 - 20 at% and the reminder being Fe and inevitable impurities, in which a steel structure is an austenite single-phase structure, and achieves weight reduction and high ductility without reducing strength.

Abstract:
The invention relates to a wire cable (12) which is produced by producing the wires already in the cable configuration by layer construction. Preferably, the wires are already formed onto terminal couplings. The wire cable (12) so produced is suitable for specific purposes only. It is advantageous in that it is not influenced by variations in quality of the starting product or by variations in manufacturing parameters. The inventive wire cable (12) is used for applications where short cables are required and where their absolute regularity can be made use of. An important field of application of the inventive method is the production of samples for obtaining background data required for optimizing wire cable construction. According to the inventive method, samples of identical basic cable structure but different wire diameters and/or lay lengths of strands, a core wire and/or the cable are produced and the characteristic features of interest are determined. In the tests, different absolute values are found. However, the values in relation to each other show influences of geometry, i.e. wire diameters and lay length modifications. A comparison with samples produced according to conventional manufacturing methods can be used to find correctional variables which can be taken into consideration when required.
Abstract:
A steel cord (10) adapted for the reinforcement of an elastomer comprises steel filaments (12,14) of a pearlitic structure. The steel cord has a plastic and elastic elongation at break of x % and a plastic and elastic elongation capability in the vulcanized elastomer of y %, the values x and y fulfilling following equation : y - 0.50 ≤ x ≤ y + 0.50, which means that the total elongation at break does not reduce considerably after embedding the steel cord into an elastomer. The steel core (10) has a high elongation capability which is largely independent of the structure of the steel cord.
Abstract:
The invention relates to a multifilament yarn containing n filaments, wherein the filaments are obtained by spinning an ultra-high molecular weight polyethylene (UHMWPE), said yarn having a tenacity (Ten) as expressed in cN/dtex of Ten(cN/dtex)=f×n−0.05×dpf−0.15, wherein Ten is at least 39 cN/dtex, n is at least 25, f is a factor of at least 58 and dpf is the dtex per filament.
