An apparatus for connecting a main casing section to a lateral casing section using, thermoset plastic molding. The apparatus is used to set a flexible sock made of a hardenable, material at a location adjacent to an intersection between the main and lateral casing sections. The sock is inflated so that it conforms to the inner surfaces of the main and lateral casing, sections. Heat is applied to the hardenable material so that the sock is cured in the inflated, operating position. Heat may be applied by releasing chemicals which provide an exothermic, reaction and/or by using a heater positioned within the sock.

Why it's free to use
- Filed March 9, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 9, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 9, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
