摘要： An adapter is affixed to a conventional weld wire feed roll assembly said adapter having a first opening through which the weld wire passes generally toward the target area. The adapter comprises a second opening which is at a skew angle to said first opening and a third opening which is also at a skew angle and having a larger diameter than to the second opening. A weld guide is inserted into the third opening and the weld guide is bent at its lower portion to intersect the center line of the first opening. Rotational means are affixed to the adapter and weld guide respectively, so that selective rotation of the adapter and weld guide will allow intersection of any point within the weld target area.

摘要： A wheel construction and arrangement wherein a wheel which has a relatively wide surface contact tire, pneumatic, for example, is mounted for rotation in a yoke which extends in the direction of travel of the vehicle which the wheel supports. The yoke is tiltable on a substantially horizontal axis which extends below the wheel axis and relatively close to the supporting surface. Lateral displacement of the body to which the yoke (and wheel) is attached will cause the wheel to tilt in that direction and any subsequent longitudinal motion in either direction of wheel travel will result in the wheel righting itself; i.e., correcting for that displacement. Conversely, tilting of the yoke and wheel to a certain degree will cause the wheel to travel in a precisely prescribed arc. The vertical plane in which the tilt axis lies passes through the area of tire contact with the supporting surface regardless of the angle of tilt.
摘要翻译：一种车轮结构和装置，其中具有相对宽的表面接触轮胎（例如气动的）的轮子被安装成用于在车轮支撑的车辆的行进方向上延伸的轭中旋转。磁轭可在基本上水平的轴线上倾斜，该轴线在车轮轴线下方延伸并且相对靠近支撑表面。轭架（和车轮）所附接的身体的侧向位移将导致车轮在该方向上倾斜，并且任何随后的车轮行进方向上的纵向运动将导致轮子自身弯曲; 即校正该位移。相反，轭和车轮在一定程度上的倾斜将导致车轮以精确规定的电弧行进。倾斜轴所在的垂直平面通过与支撑表面接触的轮胎区域，而与倾斜角无关。

摘要： A drive mechanism for converting rotary to linear movement. A portion of a drive cable is wrapped around a drive shaft. Rotation of the shaft causes the wrapped cable portion to take up a perpendicularly extending cable portion on one end, and feed out a perpendicularly extending cable portion on the other end. As it does so, the wrapped cable portion moves axially along the drive shaft. The diameter of the drive shaft and its site of rotation determine the speed of take-up, and feed out. Axial movement of the wound portion on the drive shaft is determined either by the pitch of the threads in a threaded section on the drive shaft, or the movement of control means on an externally threaded control shaft.
摘要翻译：一种用于将旋转转换为线性运动的驱动机构。驱动电缆的一部分缠绕在驱动轴上。轴的旋转使得被缠绕的电缆部分在一端上吸收垂直延伸的电缆部分，并且在另一端上馈送垂直延伸的电缆部分。如此，缠绕的电缆部分沿驱动轴轴向移动。驱动轴的直径及其旋转位置决定了卷取速度，并将其送出。卷绕部分在驱动轴上的轴向运动由驱动轴上的螺纹部分中的螺纹的螺距或外螺纹控制轴上的控制装置的运动决定。
