  • Patent number: 5680722
    Abstract: A firearm having a trigger which is pivoted to the frame, a hammer which is pivoted to the frame and biased in a forward position, a barrel which is pivotally mounted on the frame so that the breech end of the barrel can be moved between a closed position and an open position. A latch is operatively connected to the hammer and to the trigger for positioning the trigger in its cocked position when the hammer is in its cocked position and for releasably maintaining the hammer in its cocked position, and for releasing the hammer to its firing position upon manual actuation of the trigger. A first locking means is operatively connected to the barrel for preventing the barrel from moving to its open position when the hammer is in its cocked position. A second locking means is operatively connected to the barrel and to the hammer for preventing the hammer from moving to its cocked position when the barrel is in its open position.

  • Patent number: 5678341
    Abstract: A compact muzzleloader firearm has a barrel and a ramrod mounted below the barrel. The ramrod extends through a tubular member supporting a slide block connected to a hammer with struts. A spring mounted on the tubular member biases the slide block to move the hammer from a cocked position to a fire position. A manually operated safety structure on side plates adjacent the hammer prevents the hammer from moving to the fire position. The safety structure is also releasable to allow the hammer to move from the cocked position to the fire position.

  • Patent number: 5671560
    Abstract: A firearm including a frame having a grip for manually grasping the firearm, a control member movable to enable firing the firearm, a locking device including a latch element movable by an inserted key either to a locking position or to a releasing position, and a locking member movably carried by the frame. A spring urges the locking member into contact with the control member such that the locking member moves with the control member to enable firing the firearm. The locking member is located with respect to the latch element of the locking device so as to be engaged thereby when the latch element is in its locking position, to block the movement of the locking member, and thereby to prevent the firing of the firearm when the latch element is in its locking position. Two embodiments are described: a semi-automatic pistol, wherein the control member is a pivotal safety lever; and a revolver, wherein the control member is a rebound slide.

  • Patent number: 5672928
    Abstract: A method for stabilizing direct current generated by neutron activation of a plurality of interconnected .beta.-emitter (nuclear decay electron) cells, which are placed in a specific position in the out-of-core region of a light water nuclear reactor. The method entails a synergistic combination of neutron-absorbing isotopes, in specific relationship to each other, the amount of each absorber and their respective locations in the neutron flux field being chosen to render the total current-time characteristic substantially constant over a significant number of reactor full-power-years. The method enhances the current output and lifetime of the current generator by greatly deferring burn-up of the neutron absorbers. If configured as a DC voltage source for powering radiation-hardened, high-temperature integrated circuitry contained in the reactor pressure vessel, voltage regulation circuitry is not necessary.

  • Patent number: H1681
    Abstract: A continuous digester discharges pulp without mechanically engaging the pulp, by using one or more discharge transitions with one dimensional convergence and side relief. The transitions may be mounted within a pre-existing digester shell (after removal of the discharge rotor), and supported by a number of braces and/or a skirt shaped like a truncated cone. The operation of a digester, or other continuous vessel, may be controlled by automatically sensing the level of comminuted cellulosic fibrous material in the vessel and automatically controlling the introduction of dilution liquid into the vessel to discharge the material from the vessel in response to the sensing.
