A preassembled parallel wire cable creates a random cast of loops. Any of the random cast of loops is hung for transport, thus eliminating costly and time-consuming coiling and reeling operations.

A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.

A belt for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members spaced from each other along a width of the belt and extending longitudinally along a length of the belt. A jacket at least partially envelopes the plurality of tension members and forms at least one outer belt surface along a width of the belt. A groove is located in the at least one outer belt surface extending longitudinally along the length of the belt.

A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt and a plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure. A coating at least partially encapsulates the composite belt structure to improve two or more operational characteristics of the belt. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and arraying the plurality of tension elements longitudinally along a belt. A plurality of fibers are interlaced with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure to improve at least two operational characteristics of the belt.

An adjustable sports rope comprised of a hollow base rope sheath and an adjustment rope. The hollow base rope sheath is a hollow sheath with at least two openings. The adjustment rope enters into the hollow base rope sheath through one of the at least two openings and exits the base rope sheath through another of the at least two openings. The one end of the hollow base rope sheath terminates at a tie point. The end of the adjustment rope disposed furthest from the hollow base rope sheath tie point is also a tie point. By creating a tensile force between the tie point of the hollow base rope sheath and the tie point of the adjustment rope, the hollow base rope sheath will tighten on the adjustment rope, holding the adjustment rope in place.

The present invention relates to an engineered fiber bundle for reinforcement of composite materials. Specifically, the engineered fiber bundles of the present invention enhance the tensile behavior of the composites reinforced with the fiber bundles. Methods of making the same are further provided.

An elevator system includes a hoistway, an elevator car movable along the hoistway, and one or more belts operably connected to the elevator car to propel the elevator car along the hoistway. A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.

Wire-shaped perovskite devices and methods for manufacturing the same are provided. The perovskite devices have a uniform layer thickness of perovskite material on wire-shaped substrates of semi-conductor or carbon material. The method includes an electro-coating process, which advantageously allows for predictability and repeatability.

A muscle-like actuator comprises a motor with a rotatable drive shaft and a string with a shear thickening fluid (STF) embedded therein. One end of the string is attached to the drive shaft and the other end is connected to a load to form a twisted string actuator (TSA). By controlling the speed and current of the motor, the characteristics of the actuator can be changed. Multiple strings may be located in a flexible soft tube to improve the mechanical properties of the actuator.
