    • A form tie made of an expanded metal material extends between the sidewalls of a concrete form. A web traverses the sidewalls and includes, at the opposed ends of the web, first and second parallel flange walls with a supplemental web wall extending therebetween. A return wall extends from the end of the second flange wall. The use of the flange walls, supplemental webs and return walls stiffens the resulting tie so as to preclude sidewall displacement upon a static load thereon. The same elements resist longitudinal and lateral shifting of the tie and attached sidewalls during concrete pouring. The maintenance of the sidewalls by the tie during static and dynamic load conditions allow for easy form connection as well as prevents buckling and/or "blow out" of the forms during concrete pouring.
    • 由膨胀金属材料制成的成型接头在混凝土形式的侧壁之间延伸。 腹板横过侧壁,并且在腹板的相对端处包括第一和第二平行凸缘壁,其间在其间延伸的补充腹壁壁。 返回壁从第二凸缘壁的端部延伸。 使用凸缘壁,补充腹板和返回壁加固所得的扎带,以防止在其上的静态载荷上的侧壁位移。 相同的元件在混凝土浇注期间抵抗连接和连接的侧壁的纵向和横向移位。 在静态和动态负载条件下通过连接件维护侧壁允许容易的形式连接以及在混凝土浇注期间防止形状的弯曲和/或“吹出”。

    • A rotary actuator for converting reciprocating motion to rotary motion including a housing having spaced-apart end plates connected by guide rods. A bellows is provided having opposite sides one of which is connected to one of the end plates, the bellows being adapted to be connected to a source of fluid under pressure so that the bellows expands from a collapsed to an expanded position. A guide plate is provided movably mounted on the guide rods with the other bellows side being connected thereto. A rack and pinion assembly is provided mounted on the other end plate, the rack being connected to the guide plate so that expansion and contraction of the bellows causes linear movement of the rack thereby imparting rotary movement to the pinion. A spring acts between the guide plate and the other end plate thus resisting expansion of the bellows and returning it to the collapsed position upon the release of fluid pressure. Adjustable stops are provided for limiting rotational movement of the pinion between predetermined first and second angularly spaced positions.
    • 用于将往复运动转换成旋转运动的旋转致动器,包括具有通过导杆连接的间隔开的端板的壳体。 一个波纹管被设置成具有相对的侧面,其中一个连接到一个端板,波纹管适于在压力下连接到流体源,使得波纹管从折叠膨胀到膨胀位置。 引导板可移动地安装在引导杆上,另一个波纹管侧与其连接。 提供安装在另一端板上的齿条和小齿轮组件,齿条连接到引导板,使得波纹管的膨胀和收缩导致齿条的线性运动,从而向小齿轮提供旋转运动。 弹簧作用在导板和另一端板之间,从而抵抗波纹管的膨胀并且在释放流体压力时将其返回到收缩位置。 提供可调止动件用于限制小齿轮在预定的第一和第二角度间隔位置之间的旋转运动。

    • A concrete form tie comprises a pair of laterally displaced sidewall support assemblies with a reinforcing web extending therebetween. The support assemblies bite into the exterior sidewall surfaces as positioned thereat by the web transversely extending between the support assemblies. The web comprises a pair of brackets as formed by a support strut extending through a notch at the top of the form sidewall with a hanger element depending therefrom. A bridge extends between the depending hangers and across a vertical cavity formed between the sidewalls. The tie resists pressures acting on the sidewalls to preclude blow out along the horizontal joints of form courses as well as lateral displacement of the sidewalls. A starter tie is disclosed for respectively securing the lower end of the first course of sidewalls to a footing. A finish tie is disclosed for maintaining the displacement of the sidewalls of the top course of forms.
    • 混凝土结构包括一对侧向移位的侧壁支撑组件,其中在其间延伸有加强腹板​​。 支撑组件咬合到外侧壁表面中,由位于支撑组件之间横向延伸的腹板定位。 腹板包括一对托架,由支撑支柱形成,支撑支柱延伸穿过形式侧壁的顶部处的凹口和从其悬挂的衣架元件。 桥接器在垂直悬挂器之间延伸并且跨越形成在侧壁之间的垂直空腔。 连接件抵抗作用在侧壁上的压力,以防止沿着横向的水平接头以及侧壁的横向位移而吹出。 公开了一种用于分别将第一道路侧壁的下端固定到基脚的起动器扎带。 公开了一种用于保持顶部形式的侧壁的位移的表带。

    • An attachment for the three-point hitch of a farm tractor including a generally vertically disposed, inverted U-shaped frame having outwardly extending lower ends connected to a pair of lower lift arms forming part of the three-point hitch of the tractor. The top portion of the frame is pivotally and longitudinally adjustably connected to a telescopically adjustable stabilizer link or bar having its forward end pivotally connected to the usual attachment point of the stabilizer link of a three-point hitch assembly provided on a farm tractor. The outer end of the stabilizer bar includes a transverse sleeve by which various devices including a round hay bale moving device can be pivotally attached. The upper surface of the longitudinally movable component of the telescopic stabilizer bar is provided with a rigid lug to which a hydraulic ram can be pivotally connected with the other end of the hydraulic ram being connected pivotally to the hay moving device or other device attached to the outer end of the stabilizer bar.
