Abstract: An apparatus and method for inserting prosthesis implants into a patient pocket. The apparatus has three openings including a prosthesis opening, a larger proximal opening, and a small distal opening. The apparatus prevents infection; eases insertion and placement; and reduces complications. In use, the inverse bellow is placed through the patient incision while allowing the bellow to be manipulated to force the prosthesis into a surgical pocket of a patient.

The apparatus prevents infection; eases insertion and placement; and reduces complications. In use, the bellow is placed through the patient incision while allowing the bellow to be manipulated to force the prosthesis into a surgical pocket of a patient. Then the bellow is rotated so the distal end becomes the proximal end and inserted into the second incision while allowing the bellow to be manipulated to force the prosthesis into the second pocket.

Abstract: An apparatus and method for inserting prosthesis implants into a patient pocket. The apparatus includes a universal bellow, prosthesis, and a retractor. The apparatus prevents infection; eases insertion and placement; and reduces complications. In use, the retractor anchors the universal bellow to the patient while allowing the bellow to be manipulated to force the prosthesis into a surgical pocket of a patient.

Abstract: The apparatus includes a funnel member, a coupling member and retractors. The funnel member is flexible and is frusto-conical in shape. The funnel member proximal end opening is larger than the distal end opening. The funnel member couples to a distal or coupling member that is located at the funnel member distal end portion. The distal or coupling member is rigid and has catches for removably coupling to the retractors. In use, the retractors anchor the apparatus to the patient while allowing the funnel member to be manipulated to force the prosthesis into a surgical cavity of a patient.

Abstract: A matrix band for dental applications including a base material and a coating. The base material has an outer surface and a tooth contact surface as well as a perimeter. The coating is applied to the tooth contact surface and extends to the perimeter of the tooth contact surface. The coating is a fluorinated ethylene propylene, polytetrafluoroethylene and polyether sulfone.

Abstract: The invented spray valve DEFINES two orifices that generate respective spray patterns. Preferably, the spray patterns are each conical in shape and coaxially configured so that the inside spray pattern is enveloped by the outside spray pattern. The spray valve includes two bias units that urge respective orifices to close, in a direction contrary to pressure exerted by a pressurized fluid supplied to the spray valve, that urges the orifices to open. The bias units are independently adjustable to control the amount by which each orifice is urged to close so that the proportional variation of the orifice opening size to a given variation in the fluid flow rate through the orifice, or equivalently, the fluid pressure differential across each orifice, maintains the continuity of the spray patterns over a broad range of fluid flow rates.

Abstract: Impurities such as PH.sub.3, AsH.sub.3, and B.sub.2 H.sub.6 may be removed from SiH.sub.4 by means of selective photolysis with ultraviolet radiation of the appropriate wavelength. An ArF laser operating at 193 nm provides an efficient and effective radiation source for the photolysis.

Abstract: In a process for the conversion of normal butane to maleic anhydride at a pressure between about 15 and 100 psig and a temperature above 675.degree. F, by contacting the normal butane with an oxygen-containing gas and an oxidation catalyst disposed in a fixed catalyst bed or set of tubes in a reactor vessel, and withdrawing an effluent comprising unreacted normal butane, oxygen, Co, Co.sub.2, N.sub.2 and maleic anhydride from the catalyst bed or tubes, improvements in yield, product quality and plant operability are obtained by rapidly cooling the effluent gas to a temperature below 675.degree. F. One method of accomplishing this is by contacting the effluent gas with cooling coils contained within the reactor but below the catalyst bed.
