Abstract: TITLE          DISPOSABLE SWAB ARTICLES AND OTHER LIKE PACKAGES     ABSTRACT OF THE INVENTION           This invention relates to disposable swab articles and other like packages comprising an applicator package having distal ends and having a foam applicator pad and a backing member adjacent thereto.  The backing member has at least one reservoir pad formed of a relatively rigid, flat sheet material and a formed material for containing the contents of the reservoir therebetween.          The flat sheet material has a slit or weakened portion in the surface of the material and the slit or weakened portion is transversely disposed of the flat sheet material, so that the slit or weakened portion is ruptured upon forcing the distal ends toward each other about the slit or weakened portion.  The contents of the reservoir are thereby released into the foam applicator pad upon pressure deforming the formed material containing the reservoir.

Abstract: 48,470 ABSTRACT OF THE DISCLOSURE In a combined cycle power plant having one or more combustion turbines and a steam turbine, a dry cata-lytic NOx removal module is disposed in each of the tur-bine exhaust stacks.  A waste heat exchanger system in-cludes an economizer coil and a pair of high pressure evaporator coils on upstream and downstream sides of the NOx removal module to generate steam for injection into the turbine combustors and for delivery to a superheater coil upstream from the upstream evaporator coil.  A bypass stack across the upstream evaporator coil is damper con-trolled to regulate the exhaust gas temperature at the entry to the NOx removal module.  A downstream low pres-sure evaporator coil generates steam for induction into the  low pressure section of the steam turbine.  Super-heated steam is supplied to the high pressure section of the steam turbine.  The compressor inlet guide vanes are closed to increase exhaust gas  temperature as  required after the upstream evaporator bypass flow reaches zero and no longer controls gas temperature. If the inlet guide vanes reach the fully closed position, reductant injection flow is shut off to terminate the NOx  removal process under  low exhaust  gas  temperature  conditions.  A plant afterburner is operated to add heat to the exhaust gas if gas temperature is too low.

Abstract: ABSTRACT OF THE DISCLOSURE   A low cost, high frequency, solid-state dimmable fluorescent ballast is disclosed which utilizes a resonant bridge inverter to provide high frequency sinusoidal power to the lamps.  One embodiment of the invention includes auxiliary windings connected to the filaments of the lamps to be powered which utilize the inductance of the resonant bridge inductor coil to maintain the voltage across the filaments during dimming.  A clamping circuit or auxiliary tuned circuit may be provided to prevent damage due to an over-voltage and over-current condition upon removal of a lamp during operation of the system.  In an alternative embodiment, the auxiliary windings, are re-placed by capacitors across each of the lamps to be powered. This also eliminates the need for the clamping circuit.  If desired, a current splitting capacitance system may be used.  Pulse width modulation of the inverter drive or variable AC or DC power supply input may be used to accomplish dimming.

Abstract: ABSTRACT OF THE DISCLOSURE        A gate station incorporates air pressure flows to direct clips in a production stream through the station and to selectively divert defective clips into a separate reject steam. Mounted on a support plate in the station are an upstream manifold, continuously supplied with low pressure air, and a downstream manifold, having a plurality of downwardly directed air ports and selectively supplied with high pressure air.  Air flow from the upstream manifold is directed laterally over the upper surface of a clip so as to enable atmospheric pressure to maintain the clip travelling through the gate station in the production stream.  If a clip is to be diverted, the downstream manifold is injected with high pressure air causing blasts of high velocity air through the downwardly directed ports.  This high velocity air disrupts the flow from the upstream manifold and forces the leading edge of the defective clip downwards, pressing the clip into the reject stream.
