Abstract: Accidental surgical procedures are sometimes performed on patients' limbs, tissue and/or other body parts. These surgical mistakes are tragic for the patient and cost hundreds of millions of dollars each year in lawsuits and damage awards against doctors, hospitals and/or other health care providers. Media attention has exposed this disturbing trend, but there has been no practical solution to the problem until the advent of the present invention.

Abstract: From prior oral hygiene devices, this invention, in its preferred embodiment, is dry and intended for oral use in cleaning and polishing the teeth and for cleaning the gums, tongue, and surrounding mucosa of the mouth and in plaque removal, with the user's own mouth furnishing the only liquid required, which reconstitutes, in situ, the ingredients which are dehydrated and/or impregnated within a membrane.

Abstract: A reactor tube for a high temperature chemical reactor having a precisely controllable porosity comprises a plurality of layers of a fabric of a fibrous refractory material such as carbon or graphite cloth. Difficulties connected with the handling of carbon cloth, which has an extremely high coefficient of friction, are substantially eliminated by winding the cloth on a mandrel to form the reactor tube. After winding, the mandrel is contracted, allowing its removal without damaging the inside surface of the tube. Heating elements for the high temperature chemical reactor are also formed by winding carbon cloth on a mandrel. A preferred embodiment of the reactor contemplates that a plurality of such heating elements be positioned radially outwardly of the reactor tube.
