Abstract: A trough soaking device for use in a process for complete wet removal of asbestos insulation covering from pipes, joints, and valves comprising: a flexible waterproof sheet material having disposed at its shortest ends a strip of sealing means for placement about pre-formed outermost adherent contact points on an asbestos covered pipe, and sleeve means at its longest ends to accommodate insertable support rods; a pair of support rods for insertion into a portion of said sleeve means; and at least a pair of saddles containing arched-out semi-circles for placement over pre-formed innermost adherent contact points on an asbestos covered pipe; said saddles containing slot means disposed at its lengthwise ends to accommodate press-fitting of support rods disposed in said sleeve means when said sealing means of said shortest ends of said waterproof sheet material are sealed together over said pre-formed outermost adherent contact points on said asbestos covered pipe.

Abstract: A medical instrument including a tubular extension within which and to which two movable end effectors, such as jaw members, are rotatably attached by a pivot. The proximal end of each end effector is pivotally attached to and butts against a drive surface of its respective arm of a dual action drive member also located within the tubular extension. As the dual action drive member is moved proximally or distally within the tubular extension, the distal ends of the end effectors rotate or counter rotate about the pivot in opposition to one another. The dual action drive member paired arms have end surfaces which transfer, to the end effectors, the force required to rotate the end effectors toward one another, thereby reducing the shear force applied to pivot posts on the arms used to open the jaws. The dual action drive member may be used with a variety of different end effector devices including but not limited to medical grippers, hole punches, dissectors, extractors, scissors, and clamps.

Abstract: An ophthalmological apparatus for opening the eyelids to permit access to the eye, and for illuminating the eye, primarily suited for ophthalmological procedures upon the surface of the eye. In one embodiment, a pair of optical fibers is provided along the arms of a speculum.

Abstract: Method for complete wet removal of asbestos from pipes comprising placing a trough with semi-circular recesses in insertable end walls around a pipe, sealing spaces between recesses and pipe after securing trough to pipe, pouring solution on to trough to immerse pipe and soften asbestos, removing solution, cleaning off asbestos with tool, and wiping pipe with a soaked cloth.

Abstract: Device for use in wet removable of asbestos from pipes comprising a trough having end wall semi-circular recesses for receiving pipes, means for securing the troughs on pipes in manner which allows poured-in aqueous solution to completely immerse pipes and sealing means to prevent leakage of said solution from spaces between semi-circular recesses and pipe.

Abstract: A process for use in wet removal of asbestos from pipes comprising placing a trough about an asbestos covered pipe, securing said trough around said pipe, adhering a continuous seal between trough end walls and said pipe, immersing said pipe in water, to soften said asbestos, draining off the water, removing said asbestos with a tool, and wiping the pipe with an oil or water soaked rag.

Abstract: Device for use in wet removable of asbestos from pipes comprising a trough having means for securing the trough on pipes, and means to allow a poured in aqueous solution to completely immerse said pipes and prevent leakage of said solution from spaces between said pipe and said sealing means.

Abstract: A rotary cutting scissors for surgery is disclosed. The rotary scissors instrument comprises a pair of scissor blades mounted on an end of a shaft assembly for snipping away soft tissue during surgery wherein the other end of the shaft assembly is mounted within a spring-loaded rongeur handle that is adapted to be comfortably grasped by the cupped hand of a user. When the handle is squeezed, a helical drive mechanism housed in an upper portion of the handle is actuated to rotate one of the scissor blades against the other so as to cause the desired snipping action.

Abstract: A process for the production of ferrous carbonate is provided wherein a mixture of an alkali metal bicarbonate and a ferrous compound such as a ferrous salt in solution is heated to a temperature in the range of about 100.degree. C. to about 300.degree. C. for a sufficient time to allow a precipitate to form. A molar ratio of alkali metal bicarbonate to ferrous compound is at least 2:1, such a ratio giving an extremely pure precipitate of ferrous carbonate.

Abstract: A rotary cutting scissors for microsurgery is disclosed. The rotary scissors instrument comprises a pair of scissor blades mounted on an end of a shaft assembly for snipping away soft tissue during surgery wherein the other end of the shaft assembly is mounted within a spring-loaded rongeur handle that is adapted to be comfortably grasped by the cupped hand of a user. When the handle is squeezed, a helical drive mechanism housed in an upper portion of the handle is actuated to rotate one of the scissor blades against the other so as to cause the desired snipping action.The instrument further comprises an internal fiber-optic light source that emits a bright light near the scissor blades during surgery to illuminate the area being operated on so that the surgeon can see precisely what he is dealing with and thereby avoid mistakes. This light constantly illuminates the line of cut by moving in tandem with the instrument during surgery.
