Abstract: Abstract of the Disclosure Apparatus and method for water atomizing molten metal to provide a low oxygen metal powder.  A molten metal stream is introduced to an atomization vessel containing a pressurized inert gas.  The metal stream is atomized by impingement of high pressure water within the atomization vessel.  The atomization vessel has an exit aperture located so that the slurry of water and metal powder can exit from the atomization vessel only after deflection within the atomization vessel.  Inert gas contained within the atomiza-tion vessel and entrapped within the slurry during atomiza-tion begins to leave the slurry during deflection, the inert gas returning to the atomization vessel atmosphere.  The inert gas removal process continues after passage through the exit aperture and entrance into a closed degassing vessel.  In this vessel, substantially all of the inert gas is removed from the slurry by gravity separation for return to the atmosphere of the atomization vessel, and the turbu-lent conditions initially present in the slurry are substan-tially dissipated prior to passage of the slurry from the closed degassing vessel.

Abstract: Abstract of the Disclosure A two-layer, narrow bandwidth photovoltaic detector prepared from single crystal films epitaxially grown to controlled thicknesses from materials of selected compositions upon opposite parallel faces of a transparent substrate.  Alternately, the two layers may be grown layer-to-layer, perhaps with either of the layers adjoining one face of a substrate.  In either configura-tion, one of the layers serves as a filter of incident radiation while the other layer acts as a detector of radiation passing through the filter layer.  Where the layers are separated by a transparent substrate, the composition of the filter layer is chosen so that its energy gap equals or exceeds the energy gap exhibited by the composition chosen for the detector layer.  If the layers are grown layer-on-layer, the energy gap of the filter layer should exceed the energy gap of the detector layer.  Detector layer may be used as a photo-conductor or, with the creation of a heterojunction, as a photovoltaic detector.  The thickness of either or both layers may be chosen to make the layers anti-reflective at the peak wavelength responsivity (or wavelengths) of the device.

Abstract: Abstract of the Disclosure A method and apparatus for processing signals produced by a flame detector.  A phase-locked loop is used to generate a binary in-dication of whether the signal from a flame probe is within a predeter-mined frequency band.  A signal indicative of the average analog value of the resulting pulse train is produced and tested to determine whether it is in a range consistent with flame presence.  The resultant binary signal is ANDed with a binary determination of whether the average DC value of the probe signal is within a range consistent with flame pres-ence, and if both the DC and the frequency indications imply possible flame presence, then flame presence is indicated.

Abstract: Abstract of the Disclosure An improved ion-sensitive electrode is described, particularly in terms of the structure of a pH electrode and first and second processes for making the same.  The pH electrode includes a substrate, preferably of forsterite, which is configured as a wafer having a substantially planar wafer surface.  A continuous conducting layer, formed by either thin-film vapor deposition of thick-film screening processes, is formed on the substantially planar wafer surface in a desired configuration.  A first region of the continuous conducting layer, and contiguous portions of the substantially planar wafer surface, are covered by a continuous membrane layer preferably composed of a pH-sensitive glass such as Corning Code 0150 glass.  Typically, the membrane layer is formed by a thick-film process which involves the reduction of the glass to a fine powder, the mixing of the powder with an organic vehicle including an organic solvent and an organic blender to form a glass paste, and the application of the glass paste to the wafer through a wire mesh screen having an open region therethrough corresponding in configuration to that of the desired membrane layer.  The paste when applied to the wafer is fused into a continuous membrane layer by the application of heat, at a first temperature to drive off the organic solvent and a second temperature or temperatures to drive off the organic binder and to fuse the glass.  An insulated output leads is connected directly to a second region of the conducting layer.  Alternatively, an active device chip, such as that including a field effect transistor, is bonded to the wafer and interconnected with the second region of the conducting layer and with the output lead or leads.  The exposed conducting elements of the electrode, including the second region of the conducting layer, the active device chip, and all exposed portions of the leads, are covered by a fluid-tight seal.  Other ion-sensitive electrodes and variations of the aforementioned processes are described.

Abstract: WELDING PROCESS FOR PRODUCTION OF                     A STEEL PIPE     ABSTRACT OF THE DISCLOSURE        Disclosed herein is an improvement of a welding process for welding a steel pipe, wherein a gas metal arc welding is performed to form the first welding layer and a submerged arc welding is performed to form the last welding layer.  According to the conventional gas metal arc welding process, i.e. the MIG or CO2 welding processes, the combined use of a high welding current and a welding wire having a small diameter is known to bring about the rotation of the welding arc and the formation of an undercut along the toe of the weld metal.  The purpose of the present invention is to weld a steel pipe having either a large thickness or an excellent ductility at a temperature of less than -40°C, or both.  According to the present invention, the combined use of a high welding current and a wire having a small diameter is possible, by employing a gas mixture containing an inert gas as a major part thereof and CO2 as an additional part thereof as a shielding gas.  In addition, by adequately selecting the wire extension, the gas metal arc welding is improved to provid the features of:  deep and round penetration; stable arc formation with stiffness of the arc, and; high metal deposition rate.
