摘要： A pressure sensitive valve is mounted on the barrel of a magnet wire spool to be closed by wire wrapped on the barrel. Superatmospheric pressure is maintained internally of the barrel which is released upon opening of the valve by removal of the wire from the spool. A pressure-sensing device activates in response to such pressure release to provide a warning signal or suitable control function.

摘要： A spool having an elongated barrel has a strap supported at one end at a bottom flange on the barrel with the strap passing upwardly therethrough out of the upper end thereof. The strap is removably attached to the bottom flange. A handle is affixed to the strap portion which extends beyond the upper end of the spool. A rigid frame having an upright portion is affixed to a base supported by casters. The frame has a member rigidly affixed to and transversely extending from the upper end of the upright portion which overhangs the spool. A lever having a transverse portion near one end is pivotally connected at the distal end of the transverse portion to the frame member. An arm is pivotably secured at one end to the upright portion and at the other end is engageable with the spool handle. A link is pivotably connected between said arm and the transverse portion to provide a toggle linkage. A downward force applied to the end of the lever serves to lift the arm and the spool by means of the engagement between the arm and the handle whereas an upward force lowers the spool. The toggle linkage serves to lock the spool in the lifted position.
摘要翻译：具有细长筒体的卷轴具有在筒的底部凸缘上的一端处支撑的带，其带从其上端向上穿过。带可拆卸地连接到底部法兰。手柄固定在带部分上，该带部分延伸超出卷轴的上端。具有直立部分的刚性框架被固定到由脚轮支撑的基座上。框架具有刚性地固定并且从垂直部分的上端横向延伸的部件，该直立部分的上端伸出卷轴。具有靠近一端的横向部分的杠杆在横向部分的远端枢转地连接到框架构件。臂在一端可枢转地固定到直立部分，并且另一端可与卷轴手柄接合。连杆可枢转地连接在所述臂和横向部分之间以提供肘节连杆。施加到杆的端部的向下的力用于通过臂和手柄之间的接合提升臂和线轴，而向上的力降低线轴。肘节联动装置用于将卷轴锁定在提升位置。

摘要： A spool barrel has flat sides which preferably are tapered from one end to the other. Rounded corners are formed between adjacent side edges. Each of the corners has a plurality of wire receiving ridges whereby the first or base layer of wire windings on the spool will nest in the grooves or channels between the ridges and be held thereby against axial movement on the spool barrel. A molded spool barrel having an integral molded lower flange has a molded upper flange removably attached to the upper barrel end.
摘要翻译：卷筒筒具有平坦的侧面，其优选地从一端到另一端逐渐变细。在相邻的侧边缘之间形成圆角。每个角部具有多个电线接收脊，由此，线轴上的线绕组的第一或第二层将嵌套在脊之间的槽或通道中，并且由此抵抗在线轴筒上的轴向运动。具有整体成型的下凸缘的模制卷筒筒具有可移除地附接到上筒端的模制上凸缘。
