摘要： A gas tube fail safe device for use in individual subscriber circuit telephone mmodules and related equipment, in which a fusible element is adapted to by-pass the conductive function of the gas tube in the event of gas tube failure. In one embodiment the construction provides for the fusing of the fusible element upon the occurrence of a sustained current overload. In another embodiment, this operation is supplemented by provision of secondary air gap means operative upon the occurrence of momentary excess voltage surges in the presence of a defective gas tube.

摘要： The front panel of a table saw has a lever which controls the elevation of the saw blade relative to the saw table. The elevation control lever is also coupled to a bevel control means for tilting the saw blade (and its driving motor) with respect to the table. The combination of these translational and bevel movements results in a relatively large traverse of the elevation control lever. The elevation control lever projects through an opening in the front panel of the housing for the table saw, and this opening is of sufficient size and shape to accommodate the total excursion of the elevation control lever in its traverse. An articulated cover means is provided within the housing to prevent dust from entering into the housing via the opening, as well as to prevent inadvertent contact with the operating mechanism. This articulated cover means includes a first cover member which is disposed substantially flush against the opening on the inside of the front panel. This first cover member, which pivots in response to pivotal movement of the bevel control means (and the elevation control lever coupled thereto) has a size and shape sufficient to substantially cover the opening in the front panel in all positions of the bevel control means. The elevation control lever extends through an opening in the first cover member, and the opening is elongated to accommodate the translational movement of the elevation control lever. A second cover member is carried by the elevation control lever and substantially covers the elongated opening in the first cover member. The combination of the first and second cover members thus provides for a total coverage of the opening in the front panel of the saw housing, for all translational movements of the elevation control lever, and at any given setting of the bevel control means.
摘要翻译：台锯的前面板具有控制锯片相对于锯台的高度的杠杆。升降控制杆还联接到斜面控制装置，用于相对于工作台倾斜锯片（及其驱动电动机）。这些平移和斜面运动的组合导致升高控制杆的相对较大的横移。升降控制杆通过用于台锯的壳体的前面板中的开口突出，并且该开口具有足够的尺寸和形状，以适应升降控制杆在其横移中的总偏移。铰链式盖装置设置在壳体内，以防止灰尘经由开口进入壳体，并且防止与操作机构的无意接触。该铰接盖装置包括第一盖构件，该第一盖构件基本上与前面板的内侧上的开口齐平。该第一盖构件响应于斜面控制装置（和与其连接的升降控制杆）的枢转运动而枢转）具有足以在斜面控制装置的所有位置中基本上覆盖前板中的开口的尺寸和形状。升降控制杆延伸穿过第一盖构件中的开口，并且开口被拉长以适应升降控制杆的平移运动。第二盖构件由升降控制杆承载并且基本上覆盖第一盖构件中的细长开口。因此，第一和第二盖构件的组合因此提供锯壳体的前面板中的开口的总覆盖度，用于升降控制杆的所有平移运动，以及斜面控制装置的任何给定设置。

摘要： A switch actuator in the form of a bifurcated elongated member has a pair of legs pivoted relative to each other. In the "off" position of the switch, the legs may be pivoted relative to each other, and the actuator may be withdrawn from the switch. This precludes an unauthorized operation of the switch and the equipment controlled thereby. In the "on" position of the switch, an interlocking means precludes the relative pivotal movement of the legs, and the actuator may not be withdrawn from the switch. In the preferred embodiment, the legs of the actuator automatically engage an operating element of the switch, upon the insertion of the actuator into the switch. Thereafter, the actuator has a limited sliding movement to alternately move the switch into its "on" and "off" positions. Preferably, the switch is of the "pull on/push off" type; and the sliding movement of the actuator is in a plane which is substantially parallel to the linear movement of the switch operating element. Additionally, the actuator is provided with an enlarged outer portion to facilitate manipulation by the operator.
摘要翻译：分叉细长构件形式的开关致动器具有相对于彼此枢转的一对腿。在开关的“关闭”位置，腿部可以相对于彼此枢转，并且致动器可以从开关中撤出。这样排除了交换机的未授权操作以及由此控制的设备。在开关的“开”位置，互锁装置排除了腿的相对枢转运动，并且致动器可能不会从开关中撤出。在优选实施例中，当致动器插入开关中时，致动器的腿自动地接合开关的操作元件。此后，致动器具有有限的滑动运动，以将开关交替地移动到其“接通”和“关闭”位置。优选地，开关是“拉/关”型; 并且致动器的滑动运动在基本平行于开关操作元件的线性运动的平面内。此外，致动器设置有扩大的外部部分以便于操作者的操纵。
