Abstract: A flexible-to-rigid tube is flexible when routed and is then rigidized to increase burst strength. According to the preferred embodiments of the present invention, the flexible-to-rigid tube is included in a cooling plate assembly for transferring heat from electronic components mounted on a circuit board. In one embodiment, the flexible-to-rigid tube (while in a flexible state) includes a polydimethylsiloxane (PDMS) or other silicone containing pendant or terminal epoxy, vinyl and/or acrylate functional groups and an initiator (e.g., a sulfonium salt photoinitiator, a free radical photoinitiator, or a thermal initiator). In another embodiment, triallyl isocyanurate (TAIC) and an initiator are incorporated into a conventional PVC-based tubing material. The flexible-to-rigid tube changes from the flexible state to a rigid state via formation of a cross-linked network upon exposure to actinic radiation or heat.

Abstract: A flexible garden hose having an inner tube member made from elastic material and an outer tube member made from a non-elastic material. The inner tube member is secured to the outer tube member only at an inlet coupler and an outlet coupler. The inlet coupler is constructed to secure to a water supply provided from a conventional household water spigot. The outlet coupler is coupled to a flow restrictor allowing the inner tube member to equalize in pressure with pressurized water received from the water supply. Pressurized water expands the elongated inner tube member longitudinally along a length of the inner tube member and laterally across a width of the inner tube member thereby substantially increasing the length of the hose to an expanded condition wherein the hose contracts to a substantially decreased length when there is a decrease in pressurized water.

Abstract: A flexible tubing for fine bubble aeration is provided with an air passageway defined in part by an upper portion and a lower portion. The tubing can be made of a uniform weighted material with more material in the lower portion than in the upper portion. This makes the tubing self-orienting, in that it will tend to orient itself with micro-slits along the upper portion facing upward and the lower portion facing downward when submerged in a body of water. An automated, one-stage production line converts raw tubing material to a finished tubing product without the need for separate processing. A method of coiling the tubing places the micro-slits approximately 90° away from the surface of a spool hub, thereby avoiding a longitudinal arch in the tubing and ultimately preventing roll-over and improper slit orientation after installation in a water body.

The pipe is made of material such as high carbon content steel that allows the pipe to change its shape back to the pre-frozen shape as the water inside is thawed out.

Abstract: Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.
