Abstract: A therapeutic device is provided for use in the treatment and/or rehabilitation of injuries to bodily extremities, such as the hands or feet. In the device a capsule or chamber is provided which is at least partially filled with a Newtonian or non-Newtonian liquid. An area approximating the shape of the extremity to under therapy, such as a hand, is formed and made an integral part of the capsule such that the extremity undergoing therapy may be inserted to move freely within the liquid physically coming into contact with the liquid. In one embodiment the capsule is molded from a single piece of transparent rubber with a fluid chamber formed at one end and a glove-like area formed at the other. The fluid chamber is filled with a liquid, such as medical grade silicone or organic polymer liquid, and then the glove-like area inverted to be located within the outer walls of the capsule.

Abstract: The invention discloses an improved structural glass composition and process for manufacture. In one embodiment in which the improved structural glass may be used in isolation, the glass comprises a foamed glass core which is manufactured by supplying a glass base through which a gas is infused, either by reaction or by entrapment. As the gas to glass ratio is increased to an optimum level, the quality of the foamed glass moves from a stiff homogeneous glass which is strong in compression, weak in compression and brittle, to a foamed glass which is strong in compression, weak in tension and ductile. In a second embodiment of the invention inorganic fibers supported by a glass matrix may be wrapped around the foamed glass core. This fibrous material is generally strong in tension and also ductile. The resultant combination is a glass structure which is both strong in compression and strong in tension and which is ductile.
