An isolator decoupler comprising a shaft (1), a pulley (2) journalled to the shaft, a torsion spring (10) engaged between the pulley and a carrier (9), the torsion spring loaded in an unwinding direction, a wrap spring (11) engaged between the carrier and the shaft, the wrap spring comprising a cylindrical inner portion (94) and a planar outer portion (93) connected by a tapered portion (155), and the inner portion frictionally engaged with the shaft in a winding direction.


This disclosure relates generally to a hose coupling (100) for attachment to an end portion of a hose (128). The hose coupling (100) may include a fitting (107), a termination attachment (106), and an end termination (200). The fitting (107) may be attachable to the end portion of the hose (128). The fitting (107) may include a ferrule (104) and a stem (102). The ferrule (104) may be attached to the stem (102). The termination attachment (106) may be attached to the fitting (107) in opposing relationship to the end portion of the hose. The end termination (200) may be associated with the termination attachment (106). In some examples, the end termination (200) is threaded, welded, integrally formed, integrally machined, or otherwise associated with the termination attachment (106).

A flexible hose or a tubing having a barrier layer of polyamide 6 having an impact modifier, and/or branched molecular structure, a flexural modulus of 1 to 2 GPa and/or a tensile elongation of 100% or more. The hose may have additional layers such as an HNBR rubber inner tube, an EVM/CPE rubber blend outer cover, a textile or wire reinforcement, or the like. Permeability to ethanol- and methanol-containing fuels is very low. Permeability to B20 biofuels is very low.

A method for preparing a preblend of nano-structured carbon, such as nanotubes, fullerenes, or graphene, and a particulate solid, such as polymer beads, carbon black, graphitic particles or glassy carbon involving wet-mixing and followed by optional drying to remove the liquid medium. The preblend may be in the form of a core-shell powder material with the nano-structured carbon as the shell on the particulate solid core. The preblend may provide particularly improved dispersion of single-wall nanotubes in ethylene--olefin elastomer compositions, resulting in improved reinforcement from the nanotubes. The improved elastomer compositions may show simultaneous improvement in both modulus and in elongation at break. The elastomer compositions may be formed into useful rubber articles.

This disclosure describes systems and methods which utilize organoclays compounded with zinc acrylates to improve the performance of drive belts. In performing research on organoclays, the inventors created formulations and methods of compatibilizing organoclays with metal salts of --unsaturated organic acids and incorporating the compatibilized organoclays into the belt compound so that the planar organoclay particles are substantially aligned with the longitudinal plane of the belt. This is shown to provide a) lower Mooney viscosity (resulting in greater ease of processing), b) higher stiffness (both tensile and dynamic) c) improved tear resistance, d) lower crack growth rate and e) nearly equivalent fatigue resistance in spite of the increased stiffness. This combination of traits in the belts created utilizing the organoclay/zinc acrylate technology described herein results in an unexpectedly improved belt.
