摘要： An adjustable pitch aircraft propeller has peripherally spaced composite blades each including an elongated core of expanded rigid foam material extending from a metal base member having a reduced neck portion and an outwardly projecting flange portion. A casing or skin of plastic resin impregnated fabric material surrounds the core of each blade and extends inwardly along the neck portion and also has a flange portion overlying the flange portion of the base member. The skin material overlying the neck portion of the base member is retained by a filament winding impregnated with plastic resin, and the blade is coupled to the propeller hub by an annular lip portion which projects inwardly and overlies the flange portion of the skin material. The foam core of each propeller blade has longitudinally extending slots, and strips of resin impregnated fabric material extend through the slots to form corresponding webs which connect the skin material forming opposite side of the propeller blade.
摘要翻译：可调桨距飞机螺旋桨具有外围间隔的复合叶片，每个复合叶片包括从具有减小的颈部和向外突出的凸缘部分的金属基底构件延伸的膨胀的刚性泡沫材料的细长芯。塑料树脂浸渍的织物材料的外壳或皮肤围绕每个叶片的芯部并且沿着颈部部分向内延伸，并且还具有覆盖在基底部件的凸缘部分上的凸缘部分。覆盖在基底部件的颈部上的表皮材料由浸渍有塑料树脂的细丝缠绕部分保持，并且叶片通过向内突出并覆盖在皮肤材料的凸缘部分上的环形唇形部分联接到螺旋桨毂上。每个螺旋桨叶片的泡沫芯具有纵向延伸的槽，并且树脂浸渍的织物材料条延伸穿过狭槽，以形成连接形成螺旋桨叶片相对侧的表皮材料的相应腹板。

摘要： A hollow float bulb or shell is secured to a flexible electrical cord and encloses a housing which confines an electrical switch and defines a chamber with an inwardly projecting barrier. A weight member in the form of a metal ball is disposed within the chamber and rolls over the barrier to actuate the switch in response to tilting movement of the shell and housing. In one embodiment, a shuttle in the form of a metal frame is supported within the chamber for sliding movement and carries a switch conductor element. The shuttle frame is impacted by the ball located within the frame when the ball rolls over the barrier, and the frame is restrained by magnets to produce snap actuation of the switch.
