摘要： An AC to DC power supply is provided for supplying DC to switch voltage level detector which is used with a fault detecting circuit as the control signal source when faults are detected. The DC side of the power supply includes means for inhibiting operation of the level detector during interruptions of the AC source, even though momentarily, and thereby stop the level detector from giving spurious control signals due to the interruptions. The inhibit means consists of an electronic switch in the power supply to the level detector and a switch control circuit consisting of voltage regulating means in combination with capacitance. At normal AC voltages, the switch control keeps the switched turned ''''on'''' and during interruption it makes the switch turn ''''off.

摘要： According to the invention an AC voltage, which is a function of line current, is obtained from each line of a three phase AC source. A half-wave rectifier converts the three AC voltages into three trains of pulses of like polarity. Two different ones of the three trains of pulses are applied to the two inputs of each one of three differential integrating circuits. Each circuit integrates the difference of its inputs and gives an output voltage which is proportional to this difference. The voltages of one polarity are selected from the outputs of the three differential integrating circuits and summed. The level of this sum represents the current imbalance of the source. A level detector may be used to detect this voltage level and initiate a control function in response to a predetermined level. A time delay will usually be provided to delay the control function.

摘要： A bus duct run, consisting of a rigid tubular conductor supported inside a rigid enclosure, has a current limiting reactance incorporated in the conductor. The reactance is obtained from a portion of the conductor formed into a helix with spaced-apart turns. The helix may be a tubular conductor cut helically or a conductor wound helically.

摘要： A quick acting current limiting, high voltage fuse comprising a tubular casing made of an insulating material; one or more relatively long fusible elements wound helically on an insulating core which is located inside the casing coaxially therewith; a pair of metallic terminals which close the ends of the casing and are connected to the ends of the fusible elements; and a granular arc extinguishing material which completely fills the casing and embeds the elements and core. Each element consists of a very thin, narrow and long strip of a fusible metal such as silver having along its length in one edge a plurality of spaced notches made by cutting out small segments of strip. Each notch appears in outline on the flat side of the strip as an arc of a circle. These notches define regions of reduced cross section for initiating fusion of the strip. Their configuration and arrangement reduces the tendency of the arcs to run together as they enlarge. Their presence also produce a rapid rise in arc voltage, short melting time, and low I2t.
摘要翻译：一种快速作用的限流高压保险丝，包括由绝缘材料制成的管状外壳; 一个或多个相对长的可熔元件螺旋地缠绕在与其同轴的壳体内的绝缘芯上; 一对金属端子，其封闭壳体的端部并连接到可熔元件的端部; 以及完全填充壳体并嵌入元件和芯体的颗粒灭弧材料。每个元件由非常薄，窄和长的易熔金属条（例如银）组成，其沿着其长度在一个边缘中具有通过切割条带的小部分而制成的多个间隔开的凹口。每个切口在圆条的扁平侧呈轮廓圆弧。这些凹口限定了用于引起条的熔合的减小横截面的区域。它们的配置和布置减少了电弧放大时一起运行的趋势。它们的存在也导致电弧电压快速上升，熔化时间短，I2t低。

摘要： A pneumatic brake actuator comprises a coaxial array of a discshaped brake shoe, a cylindrical shoe carrier supported for axial movement, a compression coil spring, a fixed cylindrical carrier, a ring diaphragm, a disc-like head, a nut, and a rod secured to the movable carrier and projecting axially therefrom through the spring and through axial openings in the fixed carrier, diaphragm, head and nut. The rod is guided for axial movement by a bearing surface in the opening of the fixed carrier. It is fitted into the opening in the head and its free end is threaded into the nut so as to compress the spring between the two carriers. The diagram is located between flat surfaces on the fixed carrier and the head and is secured to the head along its outer and inner edges. An opening is provided in the head for admitting compressed air into the space between the head and the diaphragm. In operation, the spring applies the brakes and the compressed air releases them.

摘要： A high-voltage circuit breaker comprising a plurality of separate interrupter units connected in series, each unit comprising a set of main contacts, the series combination of a resistor and resistor switch in parallel with the main contacts, and an actuator for operating the main contacts. The actuator of one of these units operates the resistor switch of this particular unit and is mechanically linked with the resistor switches of all the other units so that the contacts of the other resistor switches are closed by the closing action of this one actuator. The resistor switches are opened in synchronism, each one by the actuator of its unit during contacts-opening action. During a circuit interruption, all the main contacts open simultaneously, placing all the resistors in series in the line; a few milliseconds later all the resistor switches open simultaneously to complete the opening cycle. During closing, the main contacts of the one unit close first, after which all the resistor switches close simultaneously, placing the resistors of the other units in series in the line; a few milliseconds later the main contacts of the other units close simultaneously to complete the closing cycle.

摘要： A drive comprises at least two synchronous motors coupled for driving a load. Each of the motors has an armature winding for producing a rotating magnetic field when energized with alternating current, and a main field winding for producing a multipolar steady state magnetic field when energized with direct current. At least one of the motors also has an auxiliary field winding displaced with respect to the main winding. When energized with direct current the auxiliary winding produces a second multipolar steady state magnetic field having its polar axes displaced with respect to the polar axes of the main field. In one embodiment of the invention, axial slots centrally disposed within the pole piece heads serve to retain one side of two adjacent auxiliary field coils having a span of approximately one pole pitch while in a second embodiment of the invention, one side of the auxiliary field coils extend through a plurality of axial slots in the pole piece head with the other side of the coil being situated between the head and the main field coil disposed about the body of the pole piece. Load sharing is accomplished by varying the relative values of the direct current applied to said main and auxiliary windings of the one motor.
