Abstract: A plasma arc torch having a nozzle assembly positioned adjacent the discharge end of the electrode of the torch, and wherein the nozzle assembly comprises a nozzle base defining an annular outer surface and a lower nozzle member defining an annular inner surface which is spaced from the outer surface so as to define an annular water passageway therebetween. The annular water passageway defines an angle with the longitudinal axis of the torch which is less than about 30.degree. which provides both an efficient cooling of the nozzle assembly and constriction of the plasma arc, and without unduly cooling the plasma arc.

Abstract: This invention relates to marking the yarn end of a package, which is wound at the end of a winding cycle over a narrow axial range of the package surface in the form of a yarn bead. For purposes of marking the yarn end (105) of the package (103), a marking strip (126) is used, over which the yarn (105) is wound. A winding mandrel (107) engages into the space between a yarn suction device (106) and the circumferential surface of the package, and is rotated oppositely to the direction of unwinding (112) of the package (103), thereby forming a yarn loop (110) with more than one winding. Inserted axially into the space between winding mandrel (107) and the circumferential surface of the package is the marking strip (126), over which the yarn is wound several times by reversing the rotation of the winding mandrel (107). The excessive yarn (105) of the yarn loop (110) is sucked into the yarn suction device (106), and subsequently the yarn end (105) is cut.

Abstract: A system and method to fanout, breakout and splice into optical fibers in a ribbon cable trunkline extending throughout an aircraft with optical minimal loss. Boxes are positioned at strategic locations along the aircraft's fiber optic trunkline. Within each box, one or more fanout cable assemblies are supported and terminated whereby the optical fibers in the ribbon cable are transitioned into individually jacketed fibers for connection to separate locations. When an optical fiber circuit needs to be broken out at the location of a particular box, the proper individually jacket fiber is cut and the end that results is permanently connected to a breakout connector, also positioned through the box, so that the optical circuit appears on the breakout connector outside the box where a mating connector can be used to further route the optical circuit being broken out.

Abstract: Method of hydrating lung mucous secretions in the lungs of a subject are disclosed. The methods involve administering benzamil or phenamil to the lungs of the subject in an amount effective to hydrate lung mucous secretions. The administering step is preferably carried out by inhalation administration. The method is useful in the treatment of diseases such as cystic fibrosis and chronic bronchitis.

Abstract: A foldable bed is movable between an unfolded position, in which interconnected seat, cavity, and body sections are substantially horizontally aligned and of substantially uniform depth, and a folded position, in which the body section is horizontally disposed, the seat section is horizontally disposed and overlies said body section, the cavity section is generally upright and extends between the body and seat sections. In the folded position, the seat section of the mattress is collapsible, and the cavity section of the mattress is noncollapsible. The bed frame can include a leg that is spaced away from the frame in the folded position that compresses a mattress head section, thereby forming a space within which collapsible springs of the seat section can reside. The bed can include springs having upper, intermediate, and lower runs, wherein the upper and lower runs include offset portions extending in opposite directions that are generally orthogonal to a plane defined by the spring intermediate run.

Abstract: An apparatus for bundling truss plates comprises a mechanism for forming a plurality of truss plates and a mechanism for forming these truss plates into a unitized bundle that is easily shipped, stored, and handled. The apparatus can include a mechanism for orienting each of the plurality of truss plates so that the backing members are substantially parallel to a predetermined plane, an aligning mechanism for aligning the oriented truss plates so that the peripheries of their backing members are substantially aligned, a stacking mechanism for stacking the oriented and aligned truss plates, and an interconnecting mechanism for interconnecting the stacked truss plates into a unitized bundle.

Abstract: A method of fabricating an endodontic instrument by a machining operation is disclosed, and wherein a wire-like rod composed of a titanium alloy is advanced past a rotating grinding wheel at a relatively slow feed rate, with a sufficient depth of cut to remove all of the material on a given surface without over grinding a previously ground surface, and with the grinding wheel rotating at a relatively slow surface speed. The disclosed method is able to efficiently produce endodontic instruments having a high degree of flexibility, high resistance to torsional breakage, and with sharp cutting edges along the working length.

Abstract: A machine tool is provided having a spindle mounted for movement in a direction parallel to the spindle axis, the Z direction, and a direction perpendicular to the spindle axis, the X direction. The machine tool includes a machine bed and has means mounted to the machine bed for supporting at least one tool. At least one spindle is rotatably supported on the machine bed and includes a chuck for supporting a workpiece. The machine tool includes means mounting the spindle to the machine bed for movement in the Z direction and for independent movement in the X direction. Accordingly, the workpiece supporting means may be moved proximate to the tool supporting means and the workpiece may be engaged by a tool. The machine tool may further include feeder means for feeding bar stock to the workpiece supporting means so that the bar stock may be engaged by a tool. The machine tool may also include workpiece transfer means for facilitating the transfer of workpieces to and from the workpiece supporting means.

Abstract: An elongate drainage channel capable of receiving runoff from an athletic surface is provided which includes a bottom wall and a pair of sidewalls extending upwardly from the opposed sides of the bottom wall. The drainage channel also includes a projection extending transversely outwardly from the exterior of at least one of the sidewalls and spaced at a predetermined distance below the open top for defining a height to which a subsurface layer is applied adjacent to the drainage channel. The projection is also fracturable from the sidewall so as to act as a mechanical fuse to prevent vibratory or tamping machinery from damaging the drainage channel. In another embodiment of the invention, an elongate channel section is provided which has a bottom surface which includes end portions which are shaped as generally planar reference surfaces.

Abstract: A kit of endodontic instruments which are adapted for use in performing root canal therapy, and wherein the instruments in the kit have increasing diameters and differing tapers. The instruments are designed to be used sequentially in root canal therapy, and the difference of the tapers serves to prevent the whole working length of the instruments from being engaged with the wall of the tapered canal being formed, to thereby reduce the frictional loading of the instruments and the risk of breakage.
