Abstract: ABSTRACT OF DISCLOSURE        A system wherein a first dust-containing gas current is jetted out through a jetting port.  A gas current is jetted out from a direction opposed to the first gas current, and both gas currents are made to collide with each other. The flow velocity of the dust-containing gas current is made to quickly and infinitely approach zero and only the contained dust is made to advance by its inertia force.  A washing liquid is sent into the gas collision system, and the dust in the gas current is made to collide with the washing liquid at a high velocity by its inertia force.  The dust in the gas is caught with the washing liquid.  To make the dust-contain-ing gas current collide with the gas current opposed to it, the dust-containing gas is pressed into a dust collector with means, such as a pump,and is jetted out through jetting ports opposed to each other in the dust collector.  As a means of sending the washing liquid into the system wherein the gas current collides, and wherein gas flow velocity is made to quickly and infinitely approach zero and only the contained dust is made to advance by the inertia force, the washing liquid is pre-contained in the gas or sprinkled in the system, or the jetting ports opposed to each other are dipped in the washing liquid.     The liquid pressure and jetting pressure are balanced with each other so that a film of the washing liquid may be formed in the gas current collision system.

Abstract: ABSTRACT OF THE DISCLOSURE     A constant potential single phase A. C. power welding source is connected to a thyristor network and an energy storing inductor to create a square wave welding current that is adjustable in height, and is further adjustable to allow either half-cycle to be wider than the other, the sum of two adjacent half-cycles always equaling 360°. The welding current is forced to reverse rapidly by a substantial voltage to insure conduction when the welding load is an arc to an aluminum work piece, and the aluminum tends-to rectify. The heights of the positive and negative half-cycles are simul-taneously adjustable in response to manual control and feedback signals. In addition, the ratio of the heights of the positive and negative half-cycles can be other than 1:1 by selectively enabling a conduction path through a different number of turns on the inductor during the negative and positive half-cycles, such enabling being either continuous or on an adaptive feedback basis as a function of arc length as determined by arc voltage. The height difference is effective in a step fashion since the total ampere-turns must remain constant. The thyristor network may also be re-connected for full-wave rectification for D.C. welding.

Abstract: CURVED BLADE FOR TURBOMACHINERY NOISE REDUCTION       Abstract A turbomachinery stage comprising two axially spaced blade rows, one of which is rotatable, wherein the blades of the upstream row are contoured to present a leaned wake to the downstream row. In the preferred embodiment, the blades of the upstream row extend radially from a central hub and, at a radius above the hub, are physically curved circumferentially from a radial line through the hub. The physical lean locally complements the inherent aerodynamic lean at each radius such that the integrated acoustic power of the stage is essentially at a minimum, thus maximizing the acoustic attenuation, Preferably, the constraint is imposed that the blade physical curvature is essentially smooth, continuous and without an inflection point.

Abstract: ABSTRACT OF THE DISCLOSURE         A butterfly valve assembly is disclosed having a resilient seat to compensate for wear.  The valve has a rigid body with opposing end surfaces adapted to mate with opposing flanges. The body has opposing internal end surfaces spaced inwards from and having a smaller diameter than the external parallel end surfaces, a flexible ring within the annular body is adapted to deform under uneven stresses but to return to its original shape when the stresses are released.          An annular seat of elastomeric material supports the flexible ring in a flexible relationship within the body to form a seat assembly leaving an annular space between an external surface of the seat assembly and an internal surface of the body.  The seat assembly has two external flanges, one at each end which overlap the internal end surfaces and are adapted to be clamped between the internal end surfaces and the opposing flanges.          A valve closure member is rotatably mounted to the body within the seat assembly adapted to seal with an internal surface of the annular seat and thus closes the valve.
