Latest Patents

Pessin holds a patent for an "Inflation Shape Control System for Inflatable Packers." This invention features an inflatable packer that includes a mandrel carrying upper and lower heads. The packer element consists of a normally retracted inner elastomer bladder and an outer expansible armor or carcass. The design ensures that the ends of the packer element are anchored to the respective heads. One embodiment of the invention incorporates a hydraulically operable system that applies a restraining force to the heads. This system controls the shape and deployment of the packer element during inflation, preventing the entrapment of fluid bubbles outside the element and the formation of Z-folds in the bladder. Other embodiments utilize various methods to supply the restraining force, including disc springs, frictional engagement, shearing action of materials, swaging a sleeve member, and axially crushing a sleeve member.
