    • Apparatus (10) for converting between rotational and linear movement, comprising: a body (20) configured to rotate about a first axis (A1-A2), the body (20) defining a track (51) having a surface which is asymmetric about the first axis (A1-A2); first and second rollers (33, 34) located on opposed lateral sides of the first axis (Al- A2), the first and second rollers (33, 34) each being configured to rotate about at least a second axis (CBl- CB2) inclined relative to the first axis (A1-A2) and each comprising an outer contact surface configured to engage the surface of the track (51) defined by the body (20) when the body (20) rotates, whereby in use rotation of the body (20) relative to the first and second rollers (33, 34) results in oscillating displacement of the first and second rollers (33, 34); and a pivotable rocker (30) extending between the first and second rollers (33, 34), the rocker (30) being configured to maintain contact between the surface of the track (51) defined by the body (20) and the outer contact surfaces of the first and second rollers (33, 34).
    • 用于在旋转和线性运动之间转换的装置(10)包括:身体(20),其构造成围绕第一轴线(A1-A2)旋转,所述主体(20)限定具有不对称的表面的轨道(51) 第一轴(A1-A2); 第一和第二辊(33,34)位于第一轴线(A1-A2)的相对侧面上,第一和第二辊子(33,34)各自构造成围绕至少第二轴线(CB1-CB2)旋转, 相对于第一轴线(A1-A2)倾斜,并且每个包括构造成当主体(20)旋转时由主体(20)限定的轨道(51)的表面配合的外部接触表面,由此在使用中旋转 主体(20)相对于第一和第二辊(33,34)导致第一和第二辊(33,34)的摆动位移; 以及在所述第一和第二辊(33,34)之间延伸的可枢转摇摆(30),所述摇杆(30)构造成保持由所述主体(20)限定的轨道(51)的表面与所述外部触点 第一和第二辊(33,34)的表面。

    • A vessel (10) for travelling on water comprises a hull means (20) and a keel (30) comprising a member (34) depending from the hull means, the member (34) comprising two limbs (44) each depending from a respective lateral side of the hull means (20), the two limbs (44) defining at least in part an enclosed flow path extending in a bow to stern direction, the enclosed flow path being configured to allow water incident on the vessel to flow over inner and outer surfaces of the limbs (44a, 44b). The limbs (44) each have a zero-lift surface which is angled to generate in use a component of hydrodynamic force directed away from the enclosed flow path when there is a net flow of water along the enclosed flow path.
    • 用于在水上行进的船舶(10)包括船体装置(20)和龙骨(30),龙骨(30)包括从船体装置悬挂的构件(34),所述构件(34)包括两个分支(44) 所述船体装置(20)的横向侧面,所述两个翼部(44)至少部分地限定了以弓形方式延伸到船尾方向的封闭流动路径,所述封闭流动路径被配置为允许入射到所述船舶上的水流过内部 和四肢(44a,44b)的外表面。 四肢(44)各自具有零升力表面,该零升力表面成角度以在使用时产生远离封闭流动路径的流体动力的分量,当沿着封闭流动路径存在水的净流时。
