Abstract: ABSTRACT OF THE DISCLOSURE An improved filter-grating monochromator of the type having a housing which defines radiation entrance and radiation exit slits, and having simplified construction combined with high accuracy. Means are provided within the housing for collimating radiation from the entrance slit as are an optical grating for dispersing the collimated radiation by wavelength, and means for emitting a selected portion of the dispersed radiation from the exit slit. At least one radiation filter is provided, along with means for selectively positioning the filter in the radiation path. In addition, there is provided a rotatable mount for supporting the optical grating and means for rotating the mount. The rotating means comprises a camming arm secured to the mount for rotation therewith about an axis and a cam follower which is positioned at a predetermined arm length from the axis of rotation of the mount for travel along an arc during such rotation. The arm length corresponds to the hypotenuse of a right triangle which includes the angle of rotation of the mount. A movable camming surface is positioned to advance and retract the cam follower by a distance which is proportional to the sine of the angle. Means are provided for so advancing and retracting the camming surface while simultaneously translating it along substantially the entire arc traversed by the cam follower.

Abstract: ABSTRACT OF THE DISCLOSURE     In the Stretford process wherein hydrogen sulfide, obtained in the catalytic conversion of sulfur compounds, is absorbed into an alkaline solution of the sodium salt of anthraquinone disulfonic acid (ADA) and sodium     vanadate, and eventually converted to ele-mental sulfur by a reaction of the sodium     vanadate and the hydrogen sulfide,  some of the hydrogen sulfide        under-goes side reactions and is converted to undesirable by-products, e.g., sodium sulfate and sodium thiosulfate.  These by-products were removed in the prior art by burning; however, the expen-sive salts of ADA were also burned in the process of the prior art.  In the present improvement, the sodium salts of ADA are preferentially removed in an adsorption column filled with a macroporous adsorption resin, prior to the combustion stage.          The adsorption column can be regenerated either with water or with an aqueous solution of sodium carbonate formed in the combustion stage.

Abstract: METHOD FOR WELDING FERROUS ALLOYS TO ALUMINUM      AND ALUMINUM ALLOYS OR REFRACTORY METALS by Conrad Peloquin ABSTRACT OF THE DISCLOSURE         A method for welding ferrous alloys to aluminum alloys or refractory metals includes the step of coating the portion of the ferrous alloy to be welded with an intermediate metal compound or element such as gold alloy or silver.  An accelerated particle beam is directed at the area to be welded, and is defocused so that approximately one-third of the beam energy falls on higher melting point metal, while the remainder of the beam energy is directed to the portion of the lower melting point material adjacent to the weld line and subsequently melting it.  The intermediate metal compound or element dissolves in the metal alloy having the lower melting point.  As the melted alloy solidifies, the intermediate compound or element precipitates out of solution and diffuses to the interface of the alloy having the higher melting point.  The diffused layer bonds to the higher melting point metal, to effect a metallurgical bond.

Abstract: ABSTRACT OF THE DISCLOSURE         Water-soluble .alpha.-ketocarboxylic acids are continuously converted into the corresponding amino acids in a diaphragm reactor.  The conversion is carried out in the presence of a substrate-specific dehydrogenase, ammonium ions and, as the coenzyme, nicotinamide-adenine  dinucleotide (NAD+/NADH), which had been increased in the molecular weight by linkage to a water-soluble polymer.  At the same time NADH is continuously regener-ated from NAD+ in the presence of a formate dehydrogenase and formate ions.  The diaphragm must have an average pore diameter of 1 to 3 nm.  From 0.1 to 10 mmoles/litre of NAD+/NADH linked to a poly-oxyethylene having an average molecular weight between 500 and 50,000 are used as the coenzyme.  A substrate flow containing 50 to 100% of the maximally soluble quantity (but not more than 200 mmoles per litre) of the .alpha.-ketocarboxylic acid to be reacted, in the form of a water-soluble salt, a quantity  of ammonium ions approximately equimolar to the quantity of substrate and 100 to 6,000 mmoles/litre of a formate is continuously fed to the reactor.  A differential pressure of 0.1 to 15 bars is maintained across the diaphragm.  A filtrate flow containing the amino acid formed is continuously drawn off behind the diaphragm.

Abstract: Abstract of the Disclosure A power supply system which provides a signal indicative of the status of a low-level DC voltage being supplied.  The power supply includes voltage doubler and switching transistor circuits connected to an AC power supply.  The chopped output from the switching transistor circuits is applied to the primary winding of a main power transformer.  The output from the secondary of the main power transformer is rectified, filtered and applied to the load.  The rectified output of the main transformer is sensed and compared with two reference voltages.  As a result of such comparison a status signal having a first level is generated prior to the power supply having been turned on.  A second signal level is generated when the sensed voltage reaches a first predetermined level.  If the sensed voltage falls below a predetermined level the status signal having the first level is generated.

Abstract: Exhaust Gas Scrubber for Internal Combustion Engines ABSTRACT         An exhaust gas scrubber includes a closed tank partially filled with a pool of water and a core assembly within the tank.  The assembly includes a vertical cylindri-cal mixing tube open at its opposite ends and extending above and below water level, an upwardly opening cylindrical deflector cup at the bottom of the tank with its opening concentrically spaced within the lower end of the mixing tube, and a downwardly opening cylindrical deflector hood concentrically receiving the upper end of the mixing tube.          Exhaust gases are introduced into the tank through a gas inlet tube, which extends downwardly concentrically through the deflector hood and mixing tube to discharge the gases through its open lower end into the cup.  The gases are deflected upwardly into an annular mixing and expansion cham-her within the mixing tube through an annular gas orifice defined by an upper side wall of the cup and lower side wall of the inlet tube.  As the gases enter the mixing chamber, they aspirate water droplets through an annular water orifice surrounding the gas orifice.  The water droplets and gases intermix as they rise through the mixing chamber.  The mixture further expands as it is expelled from its upper end, and is then deflected downwardly by the hood toward the pool of water.  The water droplets return to the pool, while the lighter, expanded, cleansed and cooled gases are expelled from the tank through a gas exhaust tube.  The scrubber as described can he used in either a make-up type water tank or a batch-type tank, both of which are dis-closed and characterized by a tall narrow water pool surrounding the core.

Abstract: ABSTRACT            FLOW TRANSDUCER AND APPARATUS     UTILIZING THE SAME     A turbine-type flow transducer for measuring flow rate has a tube through which liquid to be measured passes. Within the tube there is a vaned rotor member that rotates at a speed which is a function of the flow rate of the liquid passing through the tube.  Disposed on opposite sides of the tube are a light source and a photosensitive device that are so positioned with respect to the rotor that the vanes of the rotor cyclically vary the intensity of the light beam passing from the light source to the photosensitive device.  The material of which the tube is constructed is chosen to have a refractive index that is similar to that of the liquid whose flow is being measured, so that the beam of light will pass across the bore of the tube substantially unrefracted when liquid is present in the bore and be detected by the photosensitive device.
