CA 2405245

Beads of activated alumina with a mixture of glycerol and water absorbed therein are enclosed in a cloth pad which has two functionally different surfaces, one moisture permeable and the other moisture impervious. When the pad is preheated by microwave energy, moist heat is delivered by the moisture permeable surface of the pad and dry heat is delivered by the moisture impervious surface. When the pad is pre-chilled in a freezer, cold is transmitted through its impervious surface. Moisture lost in moist heat applications is replenished automatically by the glycerol, from ambient air, when the pad is not in use.

Selon l'invention, des billes d'alumines activées contenant un mélange de glycérol et d'eau absorbé dans ces dernières sont enfermées dans un tampon en tissu qui présente deux surfaces possédant des fonctions différentes, l'une étant perméable et l'autre imperméable à l'humidité. Lorsque le tampon est préchauffé au moyen d'énergie micro-onde, sa surface perméable à l'humidité fournit de la chaleur humide et sa surface imperméable à l'humidité fournit de la chaleur sèche. Lorsque le tampon est prérefrigéré dans un congélateur, sa surface imperméable transmet du froid. L'humidité perdue dans les applications de chaleur humide est reconstituée automatiquement par le glycérol, à partir de l'air ambiant, lorsque le tampon n'est pas utilisé.
