摘要： The disclosed spark source is adapted to generate electrical sparks to produce light for spectroscopic analysis of materials placed on the spark gap electrodes or introduced into the sparks. The disclosed spark source comprises a high voltage transformer having a secondary winding for supplying alternating current at a high voltage, a storage capacitor, a charging circuit including a rectifier connected between the secondary winding and the capacitor for charging the capacitor, spark gap electrodes having a spark gap therebetween, a discharge circuit including an electronic switching device connected between the capacitor and the spark gap electrodes for discharging the capacitor across the spark gap and control means for supplying a sequence of variably spaced triggering pulses to the input means of the electronic switching device for producing a sequence of spark cycles in which the capacitor is charged to substantially the same voltage for all of the spark cycles. During the intervals between sparks, the capacitor is recharged by the transformer and the rectifier. The timing of the sparks is varied, with reference to the phase angle of the alternating current, so that the capacitor is charged to the same voltage during each of the intervals between sparks. The timing of the sparks is computed to accommodate the variation in the instantaneous voltage developed by the transformer during such intervals. By varying the timing of the sparks, it is possible to vary the voltage to which the capacitor is charged, over a wide range. The electronic switching device may comprise a thyratron in parallel with a shunting diode, to carry the oppositely polarized half-cycles of the oscillatory capacitor discharge current. An inductance element may be connected in series with the thyratron to improve the commutation between the thyratron and the shunting diode. It is also advantageous to insert an inductance element in series with the shunting diode to bring about a further improvement in such commutation.

摘要： An electric spark type light source for producing light for spectroscopic analysis, comprising an analytical spark gap, an energy storage capacitor, a charging and discharging circuit for alternately charging the capacitor and causing the capacitor to discharge across the spark gap to generate sparks which produce light for spectroscopic analysis, such circuit including at least one inductance coil for causing the discharge current through the spark gap to be oscillatory and pulsating in waveform, the circuit including rectifier means for causing the discharge current through the spark gap to have at least a unidirectional component, and time gate pulse generating means for deriving time gate pulses from the circuit in synchronized relation with the oscillatory pulsating spark gap current for use in selecting repetitive segments of the light from the sparks for spectroscopic analysis. The time gate pulses may be derived from the rectifier current, the capacitor discharge current or the spark gap current. A current transformer, a threshold detector and variable delay means may be employed to generate the time gate pulses. The circuit may comprise a capacitor path including a first inductance coil, a spark gap path across the capacitor path and including a second inductance coil, and a rectifier path in parallel with the spark gap path and including a third inductance coil. The spark gap path may include electronic switching means for initiating the discharge of the capacitor across the spark gap. The rectifier means may take the form of a bridge rectifier having its alternating current input terminals connected to an alternating current power supply for charging the capacitor. The direct current output terminals of the bridge rectifier may be connected into the rectifier path for producing a unidirectional pulsating oscillatory current in the rectifier path, while also causing the oscillatory pulsating spark gap current to have at least a unidirectional component.

摘要： A nonwoven fabric is comprised of a blend of fine staple fibers and coarse staple fibers randomly oriented with the fine staple fibers having a higher melt flow than the coarse staple fibers. In the manufacture of the nonwoven fabric, same is needled whereby the needles select the fine fibers and portions of same are positioned in a plane generally transverse to the plane of the fabric. Infrared heat is used to fuse the fine fibers at overlapping portions thereof to provide integrity for the fabric. The coarse staple fibers are held in the interstices of the fabric at least partially by frictional engagement with the fine staple fibers.

摘要： A capacitor is charged to a high voltage, and then is discharged through a circuit comprising an analytical spark gap and first and second inductive elements, whereby the discharge current is oscillatory. The waveform of the discharge current is modified by a diode rectifier shunted across the series combination of the analytical spark gap and the second inductive element. To provide for adjustment of the waveform over a wide range, the second inductive element is adjustable in inductance. The first inductive element is also preferably adjustable in inductance. Provision may also be made for changing the capacitance of the capacitor. A reversing switch makes it possible to reverse the polarity of the diode rectifier. One or more control spark gaps may be connected in series with the analytical spark gap. An electronic switching device may be connected across one of the control spark gaps to initiate the discharge of the capacitor. Either or both of the inductive elements may be replaced with other reactances or impedances, such as transmission lines. Coupling may be provided between the inductive elements. Inductance or impedance may be provided in the diode circuit. The capacitor may be replaced with some other source of alternating current or pulses. The spark may be ignited by high voltage, developed at a radio frequency by a quarter wave line. The diode rectifier may be replaced with a silicon controlled rectifier, silicon controlled switch, or some other active element.

摘要： A shipping deck and shipping storage system is disclosed. The shipping deck is a generally rectangular tile member formed of a plastic material. The shipping deck is substantially planar to support cargo placed thereon. The shipping deck rests upon three or more adjacent cargo bars and a plurality of downwardly projecting legs extend from the tile member in order to limit the movement of the shipping deck and to allow for stacking of the shipping decks when not in use. The cargo bars secure within a track which is located on opposite walls of the shipping container. The shipping deck, the cargo bars, and the track within the shipping container form a system for shipping storage.
