    • Headgear apparatus allows a viewer to see objects in a periscopic direction and a normal direction simultaneously. A periscope is mounted to a headpiece that is easily supported by the viewers head. The periscope has movable mirrors and an extending periscope section to allow the viewer to change the angle of the periscopic view relative to a plane containing a normal line of sight and the peripheral distance of the periscopic view, respectively. The apparatus further has a sectional periscope, whereby sections containing the reflective elements of the periscope can be rotated relative to each other and change the periscopic view in the plane of the forward line of sight. The head gear apparatus is adapted to a mask or an underwater mask that allows a viewer to see objects in a periscopic direction and a forward direction in diverse environments such as under water.
    • 头饰设备允许观看者同时观看偏光方向和法线方向的物体。 潜望镜安装在容易被观察者头部支撑的头饰上。 潜望镜具有可移动镜和延伸的潜望镜部分,以允许观看者相对于包含法线视线的平面和透视视图的周边距离改变透视图的角度。 该装置还具有截面潜望镜,由此包含潜望镜的反射元件的部分可以相对于彼此旋转并改变在前视线的平面中的透视图。 头盔装置适用于允许观察者在诸如水下的各种环境中观察物体在偏光方向和向前方向上的掩模或水下掩模。

    • Connected to the contestant game pieces of a J-shaped racecourse game are pull cords guided at a semi-circular turn by laterally-spaced guide members and at the finish line by laterally-spaced upper guide holes in the top wall, whence the pull cords pass through radially-spaced intermediate cord guide holes on a pivoted lane-length-compensating sector gear, and finally through lower cord guide holes in a fixed guide bar to connections on the winding hubs of multiple geared spools loosely and rotatably mounted upon a stationary cross shaft. The geared spools mesh with an elongated half gear on a drive shaft rotated by an external hand crank and carrying a sector gear drive gear meshing with the sector gear teeth. The teeth terminate in a lock notch engageable by a lock pin normally slidable along the top face of the sector gear until it reaches its foremost position, whereupon the lock pin drops into the lock nut to lock the sector gear until the end of the race. The pull cords wind differently at random along the hubs of their respective geared spools, thereby causing chance to determine the winner. Disengaging the half gear from the gear spools enables the contestant pieces to be pulled along their respective lanes back to the starting gate for the next race.
    • 连接到J型赛马场比赛的参赛者游戏中,通过横向间隔开的引导构件在半圆形转弯处引导拉绳,并且在终点线处通过顶壁中的横向间隔开的上导向孔,由拉绳 通过径向间隔的中间帘线导向孔在枢转的车道长度补偿扇形齿轮上,最后通过固定导杆中的较低的帘线导向孔连接到松散和可旋转地安装在静止十字架上的多个齿轮销的卷绕轮毂上的连接 轴。 齿轮式线轴通过外部手动曲柄旋转的驱动轴上带有细长的半齿轮,并带有与扇形齿轮啮合的扇形齿轮传动齿轮。 这些齿终止在一个锁定槽口中,锁定销可以通常沿着扇形齿轮的顶面可滑动,直到达到其最重要的位置,因此锁定销掉落到锁紧螺母中,以锁定扇形齿轮,直到比赛结束。 拉绳沿其各自的齿轮线轴的轮毂随机地不同地旋转,从而导致机会确定胜者。 脱离齿轮箱的半档使得参赛者可以沿其各自的车道拉回到起始门,以进行下一场比赛。
