Abstract: Abstract of the Disclosure An elbow fitting for a tub overflow drain includes an inlet port having a flange extending radially outwardly therefrom.  A plurality of lugs extends axially from the flange to center an annular packing which is disposed about the outside of a tub overflow drain.  A hollow tubular towardly section extends to a discharge end disposed in a plane 90° to the inlet port.  A drain cover is disposed within the tub and centered about the overflow drain, with a threaded member extending therefrom into the inlet port.  A post extends from the inner bore surface of the toroidal section toward the inlet opening, and includes a tapped hole extending axially with respect to the inlet port.  A reinforcing fillet extends from the post to the upper inner bore surface of the towardly section to withstand non-axial forces exerted on the post by the threaded member engaged in the tapped hole.

Abstract: ABSTRACT   Observable changes in the electrical and optical characteristics of individual molecules adsorbed on a conductor or semi-conductor caused by the electrical and/or optical excitation or de-excitation of electrons within such molecules can be used as signals which in turn can be used to carry information and such observable information carrying changes or signals can be switched, amplified, and modulated by varying the optical as well as the electrical inputs to such molecules. in the invention electro-optical molecules are adsorbed on a substrate. The natural characteristic of such a molecule is altered by ionization or electron transfer; more specifically an electron is excited to an excited state. Electron transfer, trapping, or excitation/state change, or molecule ionization is effected and controlled as a function of (1) electric potential across an adsorbed molecule or a layer or layers of such molecules and/or (2) wavelength(s)/frequency(ies) and intensity(ies) of the incident illumination thereof. Such electron transfer, trapping, or state change causes a change in the natural or non-perturbed optical response of the adsorbed molecule. The optical response can be detected using Raman spectroscopy, preferably surface enhanced Raman spectroscopy. Such detection or analysis provides a spatial distribution of the Raman lines, each having a particular intensity or magnitude level, thus providing multioutput and multilevel operation of the device. Analysis of the frequency or spatial distribution as well as the intensity of such output signal(s) or information identifies where such electron is trapped or transferred in the adsorbed molecule. Operation is at high speed, e.g. on the order of 10-13 to 10-15 second, and is functional at conventional room ambient temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE        A fluid coupling for pressurized hydraulic sy-stems permitting the interconnection of coupling parts even while both parts are pressurized.  The coupling in-cludes interconnectable parts employing self-sealing valves, and a manually operated lever axially translates interlocking means to couple the parts.  An expansible motor assists coupling, and a second expansible motor feature utilizes supply pressurized fluid to displace the valve of the supplied part although the same is under pressure during coupling.  The coupling is of the "break-away" type wherein the parts uncouple under predetermined axial tension, and the self-sealing valves will not check under high flow rates.

Abstract: RCA 80,988 ABSTRACT A circuit has two signal paths.  The first path provides a signal with a selected magnitude and phase. The second path selectively provides either no signal or a signal with twice the magnitude and opposite phase with respect to that provided by said first path.  The signals of the two paths are combined to provide a signal with a selectable phase.  The circuit can be used in a stereo decoder in which an L+R stereo sum signal is combined with an expanded R-L stereo difference signal, provided by an expander also used for a SAP signal, to produce left (L) and right (R) stereo signals so that when the SAP signal is being reproduced, it is of the same phase in both left and right channels.

Abstract: QUENCH RING AND DIP TUBE ASSEMBLY                          ABSTRACT          An assembly of a quench liquid distribution ring and dip tube with or without a draft tube for use in a hot effluent gas quench cooling zone containing a pool of quench liquid in the bottom in combination with a vertical cylindrical free-flow refractory  lined reaction  zone of a partial oxidation gas generator.  The hot effluent gas from the reaction zone passes through a bottom central discharge outlet and passage and then through a coaxial vertical dip tube that extends down into a pool of quench liquid.  A quench liquid distribution ring that includes  an  annular  rectangular  shaped  bottom  feed  quench liquid distribution channel, surrounds the outside diameter of the dip tube at its upstream end.  A quench ring face and cover is provided that comprises a vertical cylindrical shaped leg portion and a top horizontal flat ring plate portion that extends perpendicularly outward from the upstream end of the leg  portion.   The  cylindrical  shaped  leg  portion  extends downward and overlaps the outside of the inner wall of said annular rectangular shaped quench liquid distribution channel thereby providing an annular shaped gap therebetween.  The top horizontal flat ring plate portion provides a gas and liquid tight cover with the annular quench liquid distribution channel when the two parts are bolted to a floor flange connected to the support floor for the refractory that lines the reaction zone of the gas generator.  A plurality of slot orifices pass through the inner wall of said annular distribution channel to provide  free  passage  for  the  quench  liquid  between  the distribution channel and the annular gap.  The annular gap may be kept full of quench liquid and free from gas and vapor pockets,  thereby  avoiding  poor  heat  transfer.   The  quench liquid is then evenly distributed over the inside surface of the dip tube.
