摘要： A method of riveting includes drilling a hole in a workpiece with a drill bit held in a spindle mounted on an axial centerline of a drill/rivet machine. The drill descends through a drill/suction cavity of a movable shuttle and drill chips cut by the drill bit are suctioned away from the workpiece as they are made. The drill bit is withdrawn to a level just above the drill/suction cavity, which is then moved to position a rivet insert station over the newly drilled hole in the workpiece. A rivet is blown into the rivet insert station, is guided into alignment with the hole and injected directly into the hole by air pressure. The shuttle moves a rivet die over the newly installed rivet in the hole and a driver of an electromagnetic riveter is lowered into contact with the die, which in turn is pressed against the rivet head. Another rivet die is pressed against the rivet tail on the other side of the panel by a driver of another electromagnetic riveter. Both electromagnetic actuators are energized to propel the drivers toward each other and cause the dies to upset the rivet.

摘要： A method of detecting an effluent level in an aircraft lavatory holding tank and a device for practicing the method. The device uses electrodynamic forces of different values generated by an electro-impulse solenoid to determine whether a detector is contaminated, to dislodge contaminants, and to measure the fluid level in the holding tank when the detector is clean enough to produce an accurate reading.

摘要： An asymmetric coil which has an "A" winding on one pole of the "C" core and a "B" winding of opposite helical twist, on the other pole, we can achieve relatively uniform, intense heating between the poles with relatively insignificant heating outside the poles. Only one core winding is active at one time. This coil allows us to heat uniformly to the ends of the susceptors on the ribs without remelting or overheating the welded area under the abutting spar, as FIG. 6 illustrates. The asymmetry provided by the two windings of opposite helical sense and the core design allows us to travel in either direction by activating the appropriate coil.

摘要： Nondestructive evaluation of conductive materials is disclosed wherein a magnetic field having a relatively slow rise time and a relatively fast fall time induces eddy currents in the conductive material being tested and subsurface flaws such as internal cracks or other discontinuities are detected by monitoring the magnetic field produced by the eddy currents. The magnetic field is generated by sequentially discharging two capacitor banks through a coil with the currents supplied by the capacitor banks being of opposite polarity and the first capacitive discharge exhibiting a time constant that is substantially longer than the second capacitive discharge. The initial, slowly rising portion of the magnetic field establishes magnetic flux that extends to substantial depths within the conductive material and the fast fall time of the magnetic field causes eddy currents of substantial magnitude to circulate within the region of the conductive material being examined. Flaws within the material cause perturbations in the eddy currents and induce current variations in a pickup coil during a time interval occurring shortly after the magnetic field begins to collapse. Detection equipment, connected for receiving the signal supplied by the pickup coil, monitors the amplitude of the pickup coil signal and, in some situations, its relationship in time relative to the rapid collapse of the magnetic field to determine the presence and location of a flaw.

摘要： An electromagnetic force (EMF) machine with a universal portable power supply is disclosed. The universal portable power supply energizes either a multiple turn flux concentrator or a single turn flux concentrator. The flux concentrators produce magnetic fields that create an outward tension force adapted to perform non-destructive bond tests (tension proof loading) and/or dent removal operations on panels or the like. The power supply includes a slow current pulse subsystem; a fast current pulse subsystem; slow and fast crowbars; and, a firing control. The firing control controls the production of pulses by the slow and a fast current pulse subsystems, and, the operation of the slow and fast crowbars. The slow pulse subsystem, via the flux concentrator, slowly creates a magnetic field that penetrates the panel; the fast pulse subsystem, via the flux concentrator, rapidly decreases the magnetic field, whereby a negative field gradient is produced across the panel. The negative field gradient exerts the outward tension force on the panel. Further, a set of control switches control the magnitude of the current produced by the slow current pulse subsystem; and, determine the flux concentrator to which the slow and fast pulses are to be applied. Finally, a charging circuit controls the charge level of capacitor banks forming part of the slow and fast current pulse subsystems such that a predetermined ratio exists between the pulses produced by the slow and fast current pulse subsystems.
