    • A multiple electrical switch comprising a casing, a control knob supported on the top edge of the casing for tiltable movement in four directions, a retainer horizontally mounted within the casing and a conversion knob tiltably supported by the retainer and having an upper portion projecting through the central aperture of the control knob. Upper and lower base plates are disposed on respective opposite sides of the retainer, with each of the upper and lower base plates defining a printed circuit board and having a plurality of fixed connecting contacts. The switch further comprise an insulating elastic sheet having a central portion for covering the upper portion of the conversion knob and opposite side peripheral portions for covering respective top surfaces of the upper base plate and each portion including a swell including a movable connecting contact corresponding to a respective one of the plurality of fixed connecting contacts of the upper base plate.
    • 一种多重电气开关,包括壳体,支撑在壳体的顶部边缘上的用于在四个方向上可倾斜运动的控制旋钮,水平安装在壳体内的保持器和由保持器可倾斜地支撑的转换旋钮, 控制旋钮的中心孔径。 上基板和下基板设置在保持器的相对的相对侧上,每个上基板和下基板限定印刷电路板并具有多个固定的连接触头。 开关还包括绝缘弹性片,其具有用于覆盖转换旋钮的上部的中心部分和用于覆盖上基板的各个顶表面的相对侧周边部分,并且每个部分包括包括对应于 上基板的多个固定连接触头中的一个。

    • A ship having at least its side portions and bottom portion comprised of a double hull construction consisting of an inner hull plating and an outer hull plating connected together solely, except for transverse bulkheads disposed in spaced apart relation in the lengthwise direction of the ship, by a plurality of connecting longitudinals fixed to the bulkheads, at least one of the connecting longitudinals having anti-buckling means extending in the lengthwise direction thereof and tripping means extending in the widthwise direction thereof. According to this arrangement, external forces exerted on the ship may be transmitted through the connecting longitudinals to the transverse bulkheads so that the inner and outer hull platings may be protected from buckling. The absence of transverses crossing the longitudinals considerably facilitates the automatization of welding operation. Furthermore, the fact that at least one of the connecting longitudinals has anti-buckling means extending in the lengthwise direction thereof and tripping means extending in the widthwise direction thereof assures that the longitudinals, or the inner and outer hull platings connected thereby will be more positively prevented from buckling.
    • 具有至少其侧部和底部的船舶由仅由内部船体电镀和外部船体电镀组成的双层船体构造构成,除了横向隔板之外,该横舱壁在船的长度方向上以间隔关系设置, 多个连接纵骨固定在隔板上,至少一个连接纵骨具有沿其长度方向延伸的抗弯曲装置和沿其宽度方向延伸的脱扣装置。 根据这种布置,施加在船上的外力可以通过连接的纵骨传递到横向舱壁,从而可以保护内外层钢板免受弯曲。 没有穿过纵骨的横梁大大有助于焊接操作的自动化。 此外,连接纵骨中的至少一个具有沿其长度方向延伸的抗弯曲装置,并且在宽度方向上延伸的脱扣装置确保连接的纵骨或与其相连的内外壳电镀将更积极 防止屈曲。
