Benefits of technology

"The invention provides a low-cost alternative to current water control gates for low damming heights, which are easy to transport and install. The air bladders used in the invention are easy to inflate, do not require heated abutment plates for winter operation, and can be vulcanized in a single stage vulcanization process. The air bladders can be secured to a dam spillway with a simple rectangular clamp bar, which is less expensive, easier to install, and requires less space than alternative clamping systems. The air bladders can be fitted with inter-panel seals and abutment seals to create a leak tight assembly with minimal installation time. The air bladders can be made of a material which bonds to the elastomeric body during vulcanization, and may be co-vulcanized with other components of the system. The invention also provides a simple method for inflating and controlling the air bladders, as well as a method for co-vulcanizing the air bladders with other components of the system."

Problems solved by technology

De-lamination, which can occur in some conventional designs, may reduce structural integrity or cause leakage.

Embodiment Construction

[0189] At least one embodiment of the present invention may utilize an inflated bladder stress reduction apparatus such as an extruded profile or insert which may be elastomeric in at least one embodiment and which may remain secured to the interior surface of an inflatable article (a general term used to define any inflatable object, apparatus, structure or product) when the article is inflated. This configuration may eliminate the need to remove or dissolve a profiled tool or mandrel during the manufacturing process (but the insert may indeed be removable (as simply by force, or dissolvable) if such is desired—the fact that the element is termed an insert does not preclude its removal or dissolving from the inflatable apparatus because in all cases it serves as an insert, although when it is dissolved or removed it serves as an insert only temporarily). One face on a tear drop shaped extruded profile, which may be more generally referred to as a substantially elongated, substantia...
