Abstract: An apparatus for separating, controlling, and directing a lift cord or lift chain of an architectural opening includes a body structure having first and second upper openings that are separated by an upper medial guide member that protrudes beyond the upper openings A rotatable wheel within a cavity of the body structure is configured to engage a lift cord or lift chain provided as a loop, wherein such engagement allows free passage of first and second segments of the loop through the cavity in opposing directions, while preventing free passage of the first and second segments through the cavity in the same direction. The apparatus may be coupled to a top end of a cord channel enclosure having a slider moveably engaged thereto to actuate the lift cord or lift chain, with a fixed length loop portion of lift cord or lift chain extending upward from the apparatus.

Abstract: A nacelle for a wind turbine includes a housing defining an outer wall and a heat transfer assembly embedded at least partially within the outer wall of the housing. The heat transfer assembly includes a heat transfer apparatus having a body with a flow path formed in an outer surface thereof and a working fluid configured to flow through the flow path. The heat transfer apparatus also includes a plate member arranged adjacent to the flow path of the body. As such, the plate member and the outer wall of the housing of the nacelle are configured to conduct heat from the working fluid to ambient air.
