Abstract: A gun lock utilizes an internal combination wheel which is advanced by the pressing of combination buttons which urge a combination wheel toward an unlock position. The unlocking of the gun lock enables a spring loaded rachet to be springingly urged quickly out of engagement with a main housing of the gun lock to enable the gun to be readily fired. The combination is set by the orientation and radial positioning of a series of angled blocks supported by the combination wheel. The combination setting for each advanced position of the wheel is based upon the combination wheel's position resulting from the prior movement in executing the previous combination number.

Abstract: In a method of and an apparatus for checking the degradation of the pressure vessel of a nuclear reactor with the pressure vessel of the nuclear reactor being directly measured in a non-destructive manner, a magnetic yoke having an exciting coil and a magnetic flux measuring coil is closely placed in contact with the inner wall of the pressure vessel of the nuclear reactor. The hysteresis magnetization characteristics of the closed magnetic path formed by the magnetic yoke and the pressure vessel of the nuclear reactor are measured. The coercive forces are obtained by the hysteresis characteristics. The hardness of the material comprising the pressure vessel of the nuclear reactor at the part of the magnetic path formed in the pressure vessel of the nuclear reactor is obtained from the coercive forces and the degradation of the material comprising the pressure vessel is checked from the hardness.

Abstract: A nuclear reactor plant has a nuclear reactor vessel in a containment vessel. Air ducts, sump discharge lines, service water lines and other non-process non-critical lines extending through the wall of the containment vessel can be isolated passively (i.e., without instrumentation and control systems or power) should a postulated event which raises the atmospheric temperature within the containment vessel occur. The passive containment isolation system includes an isolation valve disposed in the non-process line and an actuator responsive to the atmospheric temperature within the containment vessel. The actuator is operatively connected with the isolation valve for closing the non-process line in response to the atmospheric temperature. The actuator is preferably disposed in or adjacent a containment sump at the bottom of the reactor vessel or adjacent the reactor vessel cavity where the temperature of the local atmosphere will most rapidly rise.

Abstract: This application is dedicated to the public. A method and apparatus for reducing the emissions of a fluorinated gas from a wafer processing facility begins by providing a fluorinated exhaust gas from wafer processing tools (10) through (16) via an input line (17). The fluorinated exhaust gas is then optionally gettered via an gettering system (18) to remove oxygen from the exhaust gas. After gettering, the fluorinated exhaust gas is directed to a molten aluminum bath (44). The fluorine in the exhaust gas reacts with the aluminum to form AlF.sub.3. A measurement device (56) is used to monitor the amount of fluorine being exhausted from the molten aluminum bath (44). When the amount of fluorine in the exhaust is too high, the molten aluminum bath (44) is saturated with fluorine. The bath is then cooled to form an inert solid brick of AlF.sub.3. Therefore, fluorinated gases which are detrimental to the environment are cost-effectively removed from the output of a wafer fabrication facility.

Abstract: A new osteotomy guide for guiding saw blades when making an osteotomy cut in a bone is disclosed. Osteotomy is the surgical dividing of bone. The guide includes a base, a pair of prongs and a handle. The base includes a bore for passage of a K-wire or other guide pin. The prongs define a slot for passage of a surgical saw blade. The bore and slot are deeper than prior art osteotomy guides and thus stabilize the guide and the blade relative to the guide pin so that the plane of the saw blade remains parallel to the guide pin. This ensures that in multiple-cut osteotomy procedures all the planes of opposing cuts will exactly coincide when the cut ends are reattached.
