Abstract: To prevent snap-over of a flexible connecting tube conducting solar-heated liquid to a mirror which follows the travel of the sun through the sky and then changes to an inverted "night" position, as shown in FIG. 1 at (a), a flexible corrugated or pleated tube or hose (6) with a braid (9) to form a multi-layered structure (6,9) is surrounded by a stiffening jacket (10) in the form of a spiral metal tube with interlocking adjacent windings. The stiffening jacket has the characteristic to dampen movement of the tube and additionally the tendency to retain the tube in straight or at least single-bend position, so that unstable double bends (FIG. 1, B, C) are avoided. This substantially increases the lifetime of the tube. A lubricant (15) may be introduced between the corrugated tube (6) or the braid (9) and the stiffening jacket (10). Preferably, the braid is a wire mesh or braid (9) surrounding the corrugated tube (6).

Abstract: A convoluted conduit is especially well adapted for use in hostile environments subject to vibrations which bring on fatigue failures. To prevent the conduit from having a uniform resonance throughout its length, the convolutions have a variable wall thickness. One way this variable wall thickness may be achieved is by forming the conduit walls by wrapping tape in successive layers to form a multiple layered wall. The width of the tape may be such that each alternate convolution has more layers than its two adjacent neighboring convolutions. Another way of making the conduit is to provide a plurality of coaxially nesting tubes which cooperate to form a wall thickness. Brazing or packing material may be positioned between adjacent layers of tape to seal the conduit and to make the wall behave at that point as a single layer.
