Abstract: A moldable sink insert assembly includes a gasket that is comprised of a moldable material to conform to a sink opening in a stone countertop. Additionally, the gasket is comprised of a thermoformable material to precisely conform to the sink opening. The gasket is comprised of a deformable material to inhibit a sink positioned in the sink opening from damaging the stone countertop. A heat source is included for emitting heated air outwardly therefrom. The heat source is in thermal communication with the gasket when the heat source is positioned within a minimum distance from the gasket. In this way the gasket can be thermoformed to facilitate the gasket to be shaped to conform to the sink opening.

Abstract: A hair roller which can be heated by induction has a cylindrical core (1) formed of ferromagnetic material enclosed within a heat storage layer (2) which is heated by conduction from the core. The layer (2) is formed of cellular silicone rubber which modifies the rate of heat transfer to an outer gripping layer (4). An end cap (5) incorporates a thermo-sensitive substance (10) which changes colour when the roller is heated to its working temperature. The roller can be handled immediately after heating and provides a sustained level of heat output.
