    摘要： A locking device for a folding tool includes a spring member extending from a handle over a tool hub. The hub is formed with a notch shaped with obliquely directed sides and a stop wall spaced from the notch. The portion of the hub including the notch and the stop wall forms a bearing surface. The spring member includes a v-shaped bend that substantially matches the notch and a finger extending from the bend. In an extended position, the tool is secured by the engagement of the bend in the notch and the abutment of the finger on the hub on the bearing surface and stop wall.

    摘要： A faulted circuit detector (10) having an electrically isolated and remotely positioned indicator (14) detects fault currents in a monitored conductor (18). When a fault of a predetermined magnitude is detected, a light pulse is transmitted from the detector to the indicator via a fiber optic cable (16) where, upon receipt, the pulse is converted to an electrical pulse causing the indicator to indicate a ''fault'' state. A reset circuit (56) within the indicator resets the indicator at regular intervals to the ''normal'' state as long as a predetermined minimum voltage is present on the monitored conductor. The detector includes a temperature compensation circuit (150) and low pass filter circuit (160) so as to prevent misoperation due to varying ambient temperatures or high frequency transients. A test circuit (48, 50, 34) is also provided to allow service personnel to field-test the device with the monitored conductor in an energized state.

    摘要： The spark plug comprises an outer shell (1), a central electrode (2), an insulator (3) surrounding the central electrode (2) and at least one ground electrode (4B) connected at at least one point to the outer shell (1). At least one (4B) of the electrodes consists of an outer layer made of a corrosion resistant material (e.g. nickel or a nickel alloy) and of an inner core made of a material having good thermal conductivity characteristics and a good corrosion and erosion resistance (e.g. silver or a silver alloy). In front of the bottom end of the other electrode (2), i.e. at the spark gap (5) the inner core projects through the outer layer perpendicularly to the longitudinal axis of said one electrode (4B). Several embodiments of the spark plug as well as several methods for making the electrodes of the spark plug are described.

    摘要： A current-limiting dropout fuseholder includes multiple current paths through the fuse body. A primary current path includes a high current fusible element. A secondary current path in parallel with the primary path includes a triggering conductor that extends outside the fuse body and is connected so a moveable support. The second current path further includes a first spark gap for severing the triggering conductor upon the occurrence of a fault and the shifting of the fault current from the primary current path to the second current path. A second spark gap formed between the primary and the second current paths ensures that the fault current flows across the first spark gap for a time sufficient to sever the triggering conductor, thereby ensuring that dropout will occur.

    摘要翻译： 限流漏极保险丝座包括穿过保险丝体的多个电流路径。 初级电流路径包括高电流可熔元件。 与主路径平行的次级电流路径包括延伸到保险丝体外部并被连接成可移动支撑件的触发导体。 第二电流路径还包括用于在发生故障时切断触发导体并将故障电流从初级电流路径移位到第二电流路径的第一火花隙。 形成在第一和第二电流路径之间的第二火花隙确保了故障电流流过第一火花隙一段足以切断触发导体的时间，从而确保发生掉落。
