  • Patent number: 8904743
    Abstract: A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.

  • Patent number: 8161721
    Abstract: A cable-stranding apparatus for performing SZ-stranding of strand elements about at least one core member is disclosed. A first stationary guide member individually guides the strand elements in a spaced apart configuration and centrally passes the at least one core member. At least one hollow-shaft motor is arranged downstream of the stationary guide member. A rotating guide member is disposed in the hollow shaft and rotates with the hollow shaft according to a rotation relationship. The rotation relationship controls the rotational speed and direction of the rotating guide member to SZ-strand the strand elements about the at least one core member to form an SZ-stranded assembly. Embodiments of cable-stranding apparatus having multiple hollow-shaft motors and respective multiple rotating guide members are also disclosed.

  • Publication number: 20080209825
    Abstract: A coating system and method for assisting in the heating or cooling of an underlying structure includes applying a first seamless, elastic solar reflective membrane over the structure, applying a second seamless, elastic thermochromic membrane over the first membrane, and applying a third seamless protective membrane over the second membrane. The second membrane has a color changing material with a clear state above a first transition temperature to permit transmission of solar radiation to the first membrane to reduce structure cooling requirements, and an opaque state below a second transition temperature to absorb radiant energy and reduce structure heating requirements. In addition, a method of detecting defects in a structure includes applying a layer of thermochromic material to the structure, observing a localized area of non-uniform color associated with the thermochromic layer, and ascertaining whether a defect is associated with the localized area.
