Abstract: A microwaveable exercise putty includes a borosiloxane or stannosiloxane reaction product. The resulting reaction product is mixed with a second polysiloxane, an internal lubricant such a monounsaturated fatty acid, and a particulate material which creates heating upon subjection to microwave energy. Precipitated silica is a particularly preferred particulate material. The exercise putty may be manipulated by patients, and at the same time is capable of delivering heat to the body part undergoing the manipulation.

Abstract: An oven door stretch gasket which comprises an extruded length of silicone rubber having a relatively short hooked metal insert adhered to the interior of the ends thereof. The insert is adhered by means of room temperature vulcanizing silicone rubber cement. The hook ends are adapted to be engaged in apertures which are provided at the corners of an oven chamber in a stretching action, the openings being spaced apart somewhat more than the unstretched distance between the hook ends. To install or remove the gasket it must be stretched.The invention herein is concerned with a structure which will provide a more tenacious adherence between the insert and the length of gasket.
