Abstract: A rope comprising a plurality of yarns, where at least one of the plurality of yarns is a blended yarn comprising a plurality of first fibers and a plurality of second fibers. Abrasion resistance properties of the blended yarn are greater than abrasion resistance properties of the first fibers. A coefficient of friction of the first fibers is less than a coefficient of friction of the second fibers. The second fibers substantially define abrasion resistance and coefficient of friction characteristics of the at least one blended yarn. When the rope contacts a structural member, the first set of fibers of the at least one blended yarn substantially bear tension loads on the at least one blended yarn and at least a portion of the second fibers of the at least one blended yarn substantially lie between the set of first fibers and the structural member.

Abstract: A guide system comprising a plurality of guide members, where each guide member comprises an exposed surface and an intermediate portion between first and second end portions. The first end portion comprises a deformable detent member defining a detent projection. The second end portion defines at least first, second, and third detent edges defining a detent opening. The guide system operates in storage configuration and a plurality of use configurations. In the storage configuration, detent members of two guide members extend through detent opening of the two guide members. In the use configurations, a detent member extends through one of the detent openings such that longitudinal axes of the first and second guide members are substantially co-linear or perpendicular and the exposed faces of the first and second guide members are substantially coplanar.

Abstract: An aerosol system or method for mixing first and second materials comprising first and second container assemblies and a coupler. The first container assembly contains the second material and a propellant material that pressurizes the second material. The second container assembly contains the first material and at least a partial vacuum. The coupler comprises first and second coupler connecting portions and is arranged such that the first coupler connecting portion engages the first container assembly and the second coupler connecting portion engages the second container assembly. The propellant material and the partial vacuum in the second container assembly cause a portion of the propellant material and at least a portion of the second material to flow into the second container assembly to form a mixture in the second container assembly. The propellant material within the second container assembly forces at least a portion of the mixture from the second container assembly.
