摘要： There is disclosed a method for machining multiple holes in a workpiece to a uniform depth and at a predetermined angle to the surface of the workpiece. The method is performed by a numerically controlled machine tool which orients the workpiece in space with respect to a reference coordinate system which establishes an expected position of the surface of the workpiece. The actual position of the surface of the workpiece is determined by sensing contact between the workpiece and the boring tool. Once the actual position of the workpiece surface has been sensed, the tool is advanced a predetermined distance to provide a uniform depth cut. The expected position, the actual position, and the deviation between the two are recorded to assure that the surface of the workpiece is accurately sensed during subsequent machining steps. In order to minimize false premature sensing of the workpiece, the surface of the workpiece is coated with a nonconductive enamel, air is blown across the surface of the workpiece to remove debris, and an insulating liquid coolant/lubricant is used during the drilling of the workpiece.

摘要： A manual self-inking stamping device including a base for contacting material to be stamped, such base having a recess in which a self-inking stamp pad is supported for vertical movement with respect thereto. A depressable handle threadedly engages a shaft extending through the base from the stamp pad, and a movable member is disposed about the shaft for selective meshing engagement with the base at one end of the movable member and for engagement with the handle at the other end to lock the handle against rotational movement about the shaft. A spring disposed intermediately of the handle and the movable member urges the handle and the stamp pad upwardly and urges the movable member into engagement with the base. The handle may be depressed against the biasing force of the spring to bring the stamp pad into contact with the material to be stamped, the movable member acting as a stop to restrict the vertical depression of the handle. The stamping pressure which may be exerted against the material may be varied by adjusting the effective length of the shaft between the handle and the movable member by moving the movable member upwardly out of meshing engagement with the base and rotating the handle about the shaft.
摘要翻译： 一种手动自上墨印刷装置，其包括用于接触要冲压的材料的底座，该底座具有凹部，在该凹部中自支撑印模垫被支撑以相对于其垂直移动。 一个可按压的手柄，螺纹地接合从印模垫延伸通过底座的轴，并且可动构件设置在轴周围，用于与可移动构件一端的基座选择性啮合接合，并在另一端与手柄接合 锁定手柄以防止围绕轴的旋转运动。 设置在手柄和可动构件之间的弹簧向上推动手柄和印模垫，并且促使可动构件与基座接合。 可以克服弹簧的偏置力来抑制手柄，以使印模垫与待冲压的材料接触，可动件用作止挡件，以限制手柄的垂直凹陷。 可以施加在材料上的冲压压力可以通过通过将可移动部件向上移动离开与基部的啮合接合并使手柄围绕轴旋转来调节手柄与可动部件之间的轴的有效长度来改变。

摘要： A lid for a plastic container, which container is particularly useful for containing paint, includes a sealing flange which engages the inner surface of a rim defining the opening of the container. The sealing flange is held in engagement with the rim by a plurality of locking tabs which are integral with the lid and fit beneath an inwardly projecting lip on the flange. The flange has a generally convex configuration while the rim has a concave configuration so that the lid is prevented from moving axially out of or into the container once it is locked in place by the tabs.

摘要： A loom harness in which the rails thereof are provided with protective attachments here illustrated as nose guides, each of which is formed from a pair of opposed, interlocking molded abrasive resistant plastic elements. The elements are identical to each other and have at one end locking flanges which when fitted together, form a twist-lock assembly for removably joining the ends of the pair of elements together. At the other ends of the elements, there are provided two rows of inwardly extending, staggered opposed blocks within the elements, the blocks intermeshing when the elements are in registry and having grooves or slots which align for slideably receiving the edges of a flat removable tongue for joining the elements together. The plastic of the respective elements may be the same or different so as to provide the same or different wear characteristics. By such a construction, the nose guide is readily removable without the necessity of removing the frame from the weaving loom. Also shown is the protective attachment as a support for the heddle rod support.
