Abstract: A blade for cutting and stripping insulation from insulated electrical conductors has two blade angles leading to the cutting edge. The first angle is a gathering angle which opens onto the leading surface of the blade and provides a wide opening for gathering offset insulated conductors. The gathering angle converges toward the interior of the blade and intersects the second blade angle, which also converges toward the blade interior. The second blade angle, the cutting angle, terminates in a radius cutting edge adapted to slice the insulation. The blade walls defining the cutting angle are tangent to the cutting edge radius. The cutting angle is minimized so that the radius cutting edge provides a maximum circumferential contact with the conductor. The blade may include a stop for positively controlling the cutting stroke to avoid nicking the conductor.

Abstract translation: 用于从绝缘电导体切割和剥离绝缘的刀片具有通向切削刃的两个刀片角。 第一个角度是一个通向刀片前导表面的收集​​角，为聚集偏移绝缘导线提供了一个宽的开口。 收集角度朝向叶片的内部会聚，并与第二叶片角度相交，第二叶片角度也朝向叶片内部会聚。 第二叶片角度，切割角度终止于适于切割绝缘体的半径切割边缘。 限定切割角度的叶片壁与切削刃半径相切。 切割角度最小化，使得半径切削刃提供与导体的最大周向接触。 刀片可以包括用于积极地控制切割行程以避免切割导体的止挡件。

Abstract: Method and apparatus for molding an elastomeric component of a shaft seal while bonding it to a fluorocarbon seal lip member. The lip member is initially shaped as a flat washer, and a radially outer portion is flexed during molding to a frustoconical shape. Positive retention of the fluorocarbon washer during molding is assured. Radially inner portion of the fluorocarbon washer rests on a planar annular mold ledge, its radially outer portion overhanging a frustoconical mold surface. A ring of uncured elastomer is located above that radially outer portion and radially inwardly from the outer periphery of the ledge. The radially inner portion has a horizontal toothed mold portion with a series of concentric sharp tooth edges. This directly engages the upper surface of the washer and clamps it firmly and immovably against the ledge. When the mold is closed, the elastomer flows and forces the outer portion of the washer down on frustoconical mold surface while bonding elastomer to washer.

Abstract translation: 用于模制轴封的弹性体部件同时将其粘合到氟碳密封唇部件上的方法和装置。 唇形构件最初成形为平垫圈，并且径向外部在模制期间弯曲成截头圆锥形。 确保在成型期间积极保留氟碳清洁剂。 碳氟化合物垫圈的径向内部部分位于平坦的环形模具凸缘上，其径向外部部分伸出截头圆锥形模具表面。 未固化弹性体的环位于该径向外部的上方并且从凸缘的外周向径向向内。 径向内部具有水平齿形模具部分，其具有一系列同心尖锐的齿边缘。 这直接与洗衣机的上表面接合，并将其牢牢地固定在突出部上。 当模具关闭时，弹性体流动并迫使垫圈的外部部分向下压在截头圆锥形模具表面上，同时将弹性体粘合到垫圈上。

Abstract: The hanking machine of this invention cooperates with a lead forming machine wherein each cord, gripped near opposite ends by intermittently moving cord grippers, arrives at a discharge station where the cord, extending along a horizontal line, is released by the grippers. Two carriages are guided for motion wherein a cord clamp on each tracks said line. In initial positions of the carriages, towards which they are biased and in which their cord clamps close on a cord substantially simultaneously with its release by the grippers, they are spaced substantial distances to opposite sides of a vertical plane; in release positions, wherein they release the cord, they are substantially nearer said plane. A turntable with coiling posts spaced to opposite sides of its rotational axis, has its axis horizontal and contained in said plane and has its coiling posts projecting across said line, one above it, one below it. Hence, upon rotation, the turntable coils the cord from its center while the cord ends are guided by the carriages that are clamped to them. The carriages reach release positions and detach from the cords substantially simultaneously with conclusion of turntable rotation, whereupon the carriages return under bias to their initial positions.

Abstract translation: 本发明的绞肉机与引线成型机配合使用，其中通过间歇移动的叼纸牙在相对端被夹持的每条绳索到达放电站，其中沿水平线延伸的绳由夹具释放。 两个托架被引导用于运动，其中每个轨道夹具跟踪所述线。 在托架的初始位置，它们被偏置并且绳索夹紧在其上的绳索基本上同时被其夹紧器释放，它们与垂直平面的相对侧间隔实质距离; 在释放位置，其中它们释放绳索，它们基本上靠近所述平面。 具有与其旋转轴线的相对侧间隔开的卷绕柱的转盘具有水平的轴线并且容纳在所述平面中并且其卷绕柱突出穿过所述管线，一个在其上方，一个在其下面。 因此，旋转时，转盘将绳索从其中心线圈，而绳索端部被夹紧在其上的托架引导。 托架达到释放位置并与转盘的基本同时脱离，转盘转动结束时，托架在偏压下返回到其初始位置。
