Abstract: A thermal pad system is disclosed in which two or more thermal pads can be connected together to cover a larger region of the body than a single pad, and the joining is done in such a way that there is substantially no gap between the volumes of thermal material in each pad on the side of the pads that is applied to the user's body. Each thermal pad is substantially flat, and includes a fringe portion around a volume of thermal material, wherein the two sides are joined together to create a liquid barrier. A joining clip is used to connect two thermal pads together by lifting the fringe portions along corresponding edges of the two pads away from the side of the pads to be applied to the body, and the joining clip is configured to not just hold the fringe portion sections together, but also to urge the two volume portions together under the joined fringe portion sections.

Abstract: A connection assembly for pipes is provided. The assembly includes a pipe, a corrugated conduit, a circumferentially expandable and contractable seal positioned between portions of the conduit and the pipe and a clamp encircling the conduit, seal and pipe. The seal is circumferentially contractible to secure the conduit and the pipe together with the seal serving to effect a gas-tight seal while filling the annular gap between the conduit and pipe. Additional embodiments provide flared sleeves on the corrugated conduit and stops for limiting movement of the components.
