摘要： An over-and-under shotgun apparatus includes a radius track which serves as a hinge for articulating the barrel portion of the shotgun apparatus relative to the receiver/stock portion of the shotgun apparatus. The radius track is defined by a female or concave portion formed on the monoblock attached to the shotgun barrels, and a male or convex portion formed on the frame or receiver section. The radius track defines a pivot axis that is spaced from the radius track. The radius track provides a substantial surface area sufficient to absorb all of the recoil force generated when the shotgun is discharged. No additional abutment surfaces are needed. A further aspect of the invention involves a novel trigger assembly, including a striker which moves toward the front end of the firearm when the firearm is cocked, and moves toward the butt end of the firearm when the trigger is pulled to discharge the firearm. Yet another novel aspect of the invention relates to a four-position safety switch for selecting the firing sequence of the upper and lower barrels.

摘要翻译：一种下射式霰弹枪装置包括半径轨道，该半径轨道用作铰接件，用于相对于猎枪装置的接收器/存放部分铰接霰弹枪装置的枪管部分。半径轨道由形成在霰弹枪筒上的整体上形成的阴或凹部限定，以及形成在框架或接收器部分上的凸形或凸形部分。半径轨道定义与半径轨道间隔开的枢转轴线。半径轨道提供足够的足够的表面积，以吸收在霰弹枪排出时产生的所有后坐力。不需要附加的邻接表面。本发明的另一方面涉及一种新颖的触发器组件，其包括当枪械被起动时朝向枪支的前端移动的撞针，并且当触发器被拉动以释放枪支时朝向枪支的对端移动。本发明的另一新颖方面涉及一种用于选择上下筒的击发次序的四位安全开关。

摘要： A rotary variable differential transformer produces a substantially linear output over about 180 degrees of rotation of a rotor core. The transformer includes a base housing having a central bore, and a rotor having a shaft whose angular displacement is to be determined and a generally planar, circular rotor core mounted off-center at one end of the shaft and in a plane normal thereto. The rotor core is rotatably disposed within the opening of the base housing. Also included is a primary coil disposed in the opening of the base housing to circumscribe the shaft at a location rearwardly of the rotor core. First and second windings, with cores, are carried by the base housing and positioned about the base housing opening so that the axes of the coils are oriented radially of the opening and generally in a common plane with the rotor core. The first and second windings are connected together in series opposition. A casing surrounds the sides of the base housing and at least a portion of the rear of the base housing, and includes an opening through which the shaft projects.
摘要翻译：旋转可变差动变压器在转子芯的大约180度的旋转角度上产生基本线性的输出。变压器包括具有中心孔的基座壳体和具有要确定其角位移的轴的转子，以及安装在轴的一端偏离中心并且与其垂直的平面中的大致平面的圆形转子芯。转子芯可旋转地设置在基座壳体的开口内。还包括设置在基座壳体的开口中的初级线圈，以在转子芯的后方的位置处包围轴。具有芯的第一和第二绕组由基体壳体承载并且围绕基部壳体开口定位，使得线圈的轴线定向于开口的径向并且大致与转子芯的共同平面。第一和第二绕组串联连接在一起。壳体围绕基部壳体的侧部和基部壳体的后部的至少一部分，并且包括轴突出的开口。

摘要： A magazine for introducing a plurality of ammunition cartridges into a firearm is disclosed. Particularly, a magazine may include a first rotor configured for rotating about a first center of rotation and a second rotor configured for rotating about a second center of rotation, wherein a position of the first rotor and a position of the second rotor are fixed with respect to one another. Further, operation of the first and second rotor may cause at least one ammunition cartridge of a plurality of ammunition cartridges that are movable by the first and second rotor to move along a serpentine path. Firearm systems including such a magazine are also disclosed. Another aspect of the present invention relates to a method of introducing an ammunition cartridge into a firearm. More specifically, an ammunition cartridge may be moved along a selected serpentine path prior to introducing the ammunition cartridge into a firearm.
摘要翻译：公开了一种用于将多个弹药筒引入枪支的杂志。特别地，盒可以包括构造成围绕第一旋转中心旋转的第一转子和被配置为围绕第二旋转中心旋转的第二转子，其中第一转子的位置和第二转子的位置相对于彼此。此外，第一和第二转子的操作可以使至少一个可由第一和第二转子移动的弹药盒的弹药盒沿着蛇形路径移动。还包括这种杂志的火器系统。本发明的另一方面涉及一种将弹药盒引入火器中的方法。更具体地说，在将弹药盒引入枪支之前，弹药盒可以沿选定的蛇形路径移动。
