摘要： In order to provide a gun head of stud welder (weld gun) which maintains a proper lifting height and at the same time prevents defective welding resulting from spatter, a gun head (11) has a collet (12) to hold, place and lift a stud, and is attached movably along a gun slide (13) fixed to the body of a weld gun. It welds the stud to a workpiece (5) by lifting the stud held by the collet (12) to a predetermined height from the workpiece and after producing an arc discharge across the stud and the workpiece, presses the stud onto a portion of the workpiece and of the stud melted by the arc discharge. The gun head (11) is provided with transition means to move the entire gun head along the gun slide 13 toward the workpiece over a distance equal to the maximum stroke (14) so as to bring the weld stud into surface-contact with the workpiece and an electric current established therebetween, and lifting means to lift the collet to the predetermined height while the moved gun head is held in that position.

摘要： A device (10) for sucking up material removed by the bit of a portable drill is made in the form of a casing provided with means (16) for securing it to the drill and having at least one portion constituting a handle (11) to enable it to be gripped in one hand by the operator. The device (10) comprises a suction head (26) fitted slidingly on the casing to enable it to be kept close to the point of penetration into the surface of a body to be drilled by the bit fitted on the drill. Disposed inside the casing (19) of the device are a fan (13) with intake connected to said head (26) through a connecting duct (23,24) and with outlet blowing into a container (34), supported by the casing, for collecting the aspirated material, an electric motor (14) to actuate the fan (13), electric batteries (15) to supply power to the motor (14) through an operating switch (35). The casing of the drill alternatively comprises an electric socket designed to receive a corresponding plug mounted on the vacuum device (10) so as to supply power to the fan motor (14) by taking it from the power supply of the drill.

摘要： In an electrically powered combination screwdriver/drill (10), opposing halves (60, 62) of a ratchet type torque transmitting clutch (58) are normally biased axially apart by a compression spring (70). The output half (62) of the clutch is fixed on the output spindle (56) of the tool which is free to move axially within limits. For screwdriving operation, operator bias of the tool against the workpiece overcomes the spring, retracting the output spindle and bringing the clutch halves into engagement. An adjustable stop (78) in the nose of the tool limits axially rearward movement of the output spindle and hence depth of engagement of the clutch teeth (60, 62), thus providing a variable limit on torque transmitted. For the drilling mode, the rearward half of the clutch is cammed forward so that the clutch is firmly engaged for continuous rotation of the output spindle without specific torque limitation. An operator may switch from drilling mode to screwdriving mode and back without disturbing the torque limit adjustment of the screwdriving mode.

摘要翻译： 在电动组合螺丝刀/钻头（10）中，棘轮式扭矩传递离合器（58）的相对的半部（60,62）通常被压缩弹簧（70）轴向地分开。 离合器的输出半部（62）固定在工具的输出轴（56）上，其在限制范围内自由地轴向移动。 对于螺丝起子操作，刀具对工件的操作者偏压克服了弹簧，缩回输出主轴并使离合器半部接合。 刀具鼻部中的可调节止动件（78）限制输出主轴的轴向向后移动，并因此限制离合器齿（60,62）的接合深度，从而为传递的扭矩提供可变限制。 对于钻孔模式，离合器的后半部向前凸轮，使得离合器牢固地接合以便输出主轴的连续旋转而没有特定的扭矩限制。 操作员可以从钻孔模式切换到螺丝起子模式，而不会影响螺丝起子模式的扭矩极限调整。

摘要： A unitary bifurcated brush holder (52) for a small electric motor (10), has a pair of spaced coplanar terminal tabs (134, 136). The tabs are laterally offset from the brush holder sleeve (110), and extend axially of the motor for direct plug-in engagement with terminals (38) at the commutator end (12) of a stator assembly (24). The brush holder (50) is made from a single sheet metal stamping. The terminal tabs (134, 136) are carried at the end of a support arm (114) extending from a wall (122) of the brush holder sleeve (110). In assembly, the brush holder is mounted in an insulator (50) which includes support bosses (92, 94) for engaging and augmenting the support of the rear end of the terminal tabs.

摘要： A dust bowl (54) of a hand-held vacuum cleaner (42) is attached to a power unit (44) using top (72) and bottom (74) latches which are actuated by pushing a single actuator button (84). Both latches (72,74) are outside a sealed space through which air flows, and are thus not sources of air, soil or liquid leakage. A wishbone-shaped pusher (102) transmits mechanical actuation forces from the actuator button (84) for actuating the upper latch (72) to a spring bar (110) connected to a bottom latch cam (118). When the actuator button (84) is pushed, the spring bar (110) is correspondingly moved to release the bottom latch (74) in coordination with release of the top latch (72). A forward support member (52) of the power unit (44) cradles a portion of the dust bowl (54) to provide support and lateral stability between the elements. A tab (76) extends from the bottom of the dust bowl (54) to overlap a forward edge (78) of the forward support member (52) to provide further stability to the fit.

摘要： An electrical storage cell, having a headed current collector pin (7) protruding through a sealing grommet (12) at one end of the cell, has a short threaded portion (18) in the stem (8) of the collector pin adjacent the head (9) which increases the bite on the grommet of the stem of the collector pin passing through said grommet. The thread may be interrupted. The sealing of the stem of the collector pin in the grommet may be enhanced by the provision of a small, flexible upstand (20) formed in the grommet which is distorted and deflected inwardly on assembly to form an additional seal against the stem. The axial force required to remove a collector pin is greatly increased. A weak point may be provided so that the stem fractures before it can be extracted, the major proportion of the stem being left in the cell when the head is thus torn from the collector pin; the broken stem left in the cell provides a significant seal against leakage of the contents of the cell.

摘要： Switching mode power supply for supplying power to service equipment consuming heavy currents, in particu­lar electrical welding equipment, in which the mains voltage is rectified by a mains rectifier, the direct voltage thus obtained is converted into a high-frequency square-wave voltage by means of semi-conductor switches controlled by high-frequency and the high-frequency square-wave voltage is transformed by a transformer and is rectified by an output rectifier, wherein the conductors of each electrical circuit carrying high-frequency power in the region between mains rectifier and output of the output rectifiers are formed as thin laminated metal plates having thin-film, preferably foil, insulation lying there-between.
