    • A machine such as a machine tool includes a pair of spaced platforms. One platform (11, 31, 185, 72, 159, 142) may mount an operator such as a tool in a spindle and the other platforms (10, 20, 180, 170, 144, 163) may mount an object such as a workpiece. The spaced platforms are joined by six powered and extensible legs (20-25, 40-45, 64-69, 145-150, 166, 182-84, 187-89) joined to the respective platforms by universal joints. The length of the legs is individually manipulated to vary the position of the platforms and, therefore, the object and operator relative to each other in six axes. The powered legs may be hydraulic cylinders (20-25) or recirculating ball screw driven (195, 197, 198). The distance between the spaced platforms may be measured by separate extensible instrument arms (130, 131, 171) which join the platforms. The instrument arms may use a digital position device (238, 240) to measure the extension and contraction of the instrument arms or may use a laser interferometer (267) for that purpose. The changes in the length of the instrument arms may be used to generate signals that control the extension and contraction of the powered legs. A method is also disclosed for converting part program coordinate block instructions into instructions for varying the length of the powered legs.
    • 诸如机床的机器包括一对隔开的平台。 一个平台(11,31,185,72,159,142)可以将诸如工具的操作者安装在主轴中,并且其他平台(10,20,180,170,144,163)可以安装诸如 工件。 隔开的平台通过万向接头连接到各个平台上的六个动力和可伸展腿(20-25,40-45,64-69,145-150,166,182-84,187-89)连接。 腿的长度被单独操作以改变平台的位置,并因此改变物体和操作者在六个轴线上相对于彼此的位置。 动力腿可以是液压缸(20-25)或驱动的循环滚珠丝杠(195,197,198)。 间隔平台之间的距离可以通过连接平台的单独的可伸展的工具臂(130,131,171)来测量。 仪器臂可以使用数字位置装置(238,240)来测量仪器臂的延伸和收缩,或者可以为此目的使用激光干涉仪(267)。 仪器臂的长度的变化可用于产生控制动力腿的伸展和收缩的信号。 还公开了一种用于将部分程序坐标块指令转换成用于改变动力腿的长度的指令的方法。

    • A joint (52) for connecting arm portions (40, 42) of a ceiling or wall mounted support system includes housing members (60,62) with an annular bearing (64) interposed between opposed surfaces (82,84) thereof. The housing members are clamped together on an axle (98) such that a braking force generated between the bearing and the housing member surfaces opposes rotation of one arm portion relative to the other. A variable braking force is generated between the bearing and surfaces (206) of the housing members which are generally perpendicular to the opposed surfaces (82, 84). The variable braking force is generated by a spring (182) and is greatest when the arm supporting a piece of equipment (24, 26, 28, 56) is at its lowest point, relative to the horizontal. This overcomes the increased forces in the spring which otherwise tend to cause the arm portion (42) to drift upward.
    • 用于连接天花板或墙壁安装的支撑系统的臂部分(40,42)的接头(52)包括具有插入其相对表面(82,84)之间的环形轴承(64)的壳体构件(60,62)。 壳体构件在轴(98)上夹紧在一起,使得在轴承和壳体构件表面之间产生的制动力相对于一个臂部相对于另一个的旋转。 在壳体构件的轴承和表面(206)之间产生可变制动力,其大致垂直于相对表面(82,84)。 可变制动力由弹簧(182)产生,并且当支撑一件设备(24,26,28,56)相对于水平线处于其最低点时的臂是最大的。 这克服了弹簧中的增加的力,否则倾向于使臂部分(42)向上漂移。

    • The invention relates to a windshield wiper for motor vehicles, comprising a support bracket (1) for connection to a wiper arm that is fastened on a motor vehicle. Said support bracket (1) has a substantially U-shaped cross-section and at least one support arm detent recess (7). The windshield wiper further comprises a lower bracket (2) for connection to the wiper blade rubber, said lower bracket (2) having a substantially U-shaped cross-section, at least one lower bracket detent recess (11) and being at least partially enclosed by the support bracket (1). The at least one lower bracket (2) is articulated to the support bracket (1) via at least one joint (3). Said joint (3) comprises a joint base (12) that is at least partially enclosed by the lower bracket (2), at least one lower bracket detent element (13) linked with the joint base (12) and adapted to engage with the at least one lower bracket detent recess (11) and at least one support bracket detent element (16) provided on the at least one lower bracket detent element (13) adapted to engage with the least one support bracket detent recess (7).
