Abstract: An indirect firing fastening tool with an anti-firing trigger support. The tool comprises, in one case, an axially movable equipment with a tip guide projecting from the case to drive a fastening member into a support material, a reception housing for a fastener charger and anti-firing safety means to prevent the recoil of the tip guide. Advantageously, an anti-firing trigger support is mounted on said reception housing to convert the tool into a mono-firing tool, the trigger being arranged to cooperate with the anti-firing safety means so as to remove them and authorize firing.

Abstract: Disclosed herein is a rotary lockup action including a firing mechanism for a firearm. The firearm including a receiver having a cavity therein configured to accept the firing mechanism. The firing mechanism comprising a bolt guide rail fixed to the inner surface of the cavity of the receiver. The firing mechanism also comprises a bolt sliding along a longitudinal axis on the bolt guide rail. Also disclosed is a change handle rotatably mounted to the bolt so as to rotate relative thereto about a vertical axis orthogonal to the longitudinal axis. The charge handle may be mounted to the bolt so as to longitudinally reposition therewith.

Abstract: An ambidextrously operated charging handle for use with the M16 family of firearms is provided. The charging handle provides a latch mechanism consisting of two extended handles which are in operational communication with each other. Either handle may be independently retracted to disengage the latch mechanism of the charging handle from the host firearms receiver. The spring-biased mechanism of the charging handle is sheltered within the interior of the charging handle thereby protecting it from the elements. Further, an improved axial pin has been provided to secure the handles of the latch mechanism to the grasping portion of the charging handle.

Abstract: A firearm with safety mechanism in one embodiment comprises a receiver, a trigger-actuated firing mechanism with movable trigger operable to discharge the firearm, and a safety mechanism configured to arrest the firing mechanism. The safety mechanism is movable between a first position preventing movement of the trigger and a second position allowing movement of the trigger for discharging the firearm. In one embodiment, an elongated stock bolt attaches a buttstock to the receiver. The stock bolt passes through a portion of the safety mechanism to engage the receiver. This allows an operating button of the safety to be ergonomically mounted on a top surface of the firearm above the stock bolt. In one implementation, the firing and safety mechanisms may each be operably mounted in a fire control module disposed in the receiver and removable therefrom as a separate self-supported unit.

Abstract: An ambidextrous receiver and bolt operating assembly for use in combination with a standard bolt for a Ruger® 10/22® rim-fire firearm action. A receiver housing is configured to function with the original Ruger® 10/22® firearm bolt and has an ejection port which is smaller than the ejection port of the original Ruger® 10/22® receiver and which does not include a bolt handle reciprocation opening. The receiver housing also includes a longitudinally extending upper guide channel and an opening at an aft end of said channel. A bolt closure mechanism is adapted to bias the original Ruger® 10/22® firearm bolt into battery and to be received in a seat of the original firearm bolt. The engagement member does not include a laterally extending bolt operating handle. An ambidextrous charging handle is positioned in the channel and has a forward portion including a hook portion adapted to retract the original firearm bolt during rearward movement of said handle.

Abstract: A modified toggle link assembly for a lever action rifle including a modified slide channel that, in at least one embodiment, produces a shorter lever stroke and smoother lever cycle. The modified toggle link may also include a modified profile which defines a hump on an upper surface of the rearward link of the toggle link and a corresponding recess on the forward link. This hump allows for the modified geometry of the slide channel. The slide channel may be a modified straight path or a compound, or non-linear path.

Abstract: A pump gun (10) comprises a barrel (11), a main stock part (12), a fore stock (12) supported in longitudinally displaceable manner and is linked to a breech lock (17) which, in the closed position of the pump gun (10), can be made to engage the rearward barrel end (21). The breech lock (17) and the fore stock (12) are linked to each other in a manner that upon displacing the fore stock (12), the breech lock (17) can be driven in the opposite direction to that of the fore stock (12). As a result, the pump gun (10) may be safely operated without recourse to a stop and, in the ready to fire initial state, is devoid also of any pumping excursion gap. The invention moreover offers a weapon matching marksman ergonomics and esthetics in its closed or ready to shoot state.

Abstract: It has been discovered that ?-L-2?-deoxynucleosides are active against drug-resistant hepatitis B virus with mutations. A method for treating lamivudine resistant HBV (M552V) in a host is provided that includes administering a ?-L-2?-deoxynucleoside or its pharmaceutically acceptable salt, ester or prodrug. In addition, a method for preventing lamivudine resistant HBV (M552V) mutation from occurring in a naïve host is provided that includes administering a ?-L-2?-deoxynucleoside or its pharmaceutically acceptable salt, ester or prodrug. A method for preventing and/or suppressing the emergence of the HBV double mutant (L528M/M552V) in a host is also provided that includes administering a ?-L-2?-deoxynucleoside or its pharmaceutically acceptable salt, ester or prodrug.

Abstract: A device that can be used to treat appendage ailments is provided. The device, or appendage sleeve, can be used for wounds, cuts, and blisters, as well as joint related ailments, such as arthritis and carpal tunnel syndrome.

Abstract: A lever action firearm having a receiver, a hammer, a lever pivotal about a fixed point, a bolt and a link which link is pivotal on both the bolt and the lever. The pivotal lever includes first surface means to engage second surface means on the hammer to cause the hammer to be cammed back during unloading. The lever, link and bolt are configured such that when they are in the fire position and are subjected to forces of firing they function as a joint lock to prevent unloading of the bolt and lever. Locking surfaces on the receiver and bolt strengthen the joint lock at the moment of firing.

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.

Abstract: A break open sporting firearm with one to four barrels that lock up in line directly behind the chambers for strength and rigidity.The load from firing is taken up by two or more circularly spaced lugs in the breech engaging with mating lugs on the frame.A rotating breech plate slider and hinge within the breech are the functioning means for this invention.

Abstract: In a multiple-barrel firearm with removable lock housing, the two axially moveable strikers are arranged in superposed relationship, preferably being angular and provided with grooves or edges; this arrangement permits, even in case of only one solid sidewall, a favorable guidance of the strikers and contributes considerably toward making the lock housing very narrow. Since, in this firearm, the movement of a cocking bar just as the movement of firing pins takes place approximately in parallel to the movement of the strikers, the advantage is obtained in addition to a relatively simple structure that the energy for cocking coil springs guided by means of guide pins can be at a minimum as well. The guide pins connected with the strikers also take over safety functions.
