Abstract: A monodisperse aerosol generator forms a stable jet of liquid at a velocity allowing columnar breakup into droplets of uniform size and spacing. To prevent degradation of the monodisperse aerosol, it is dispersed by entrainment in a high velocity gaseous stream. To provide an interface for direct injection into a mass spectrometer or to interface a liquid chromatograph with a mass spectrometer, the generator is followed by a desolvation chamber operating at about atmospheric pressure and a multistage pressure reducer which evacuates solvent vapor and gaseous medium to form a high momentum, solvent-depleted solute aerosol beam which is input into the mass spectrometer. To permit the analysis of higher molecular weight molecules that may be either involatile or thermal sensitive, a fast atom bombardment (FAB) source is used for the production of FAB mass spectra.

Abstract: A solid state infrared source is disclosed which is capable of modulation of the intensity of broadband infrared radiation. A silicon semiconductor body is provided with doped regions which have high emissivity for infrared and an intrinsic region which has low emissivity and low absorption for the infrared. The device is heated and maintained at a temperature of about 500.degree.K to effect the infrared radiation from the doped regions. Modulation is effected by controlling the presence of carriers in the intrinsic region, so as to modify the broadband infrared radiation. The modulating carriers may be due to optical modulation or they may be injected electrically. In either case, the heating may be effected by an external device or the doped regions may also provide a heating PIN diode structure which is forward biased in controlled fashion to attain the desired temperature.

Abstract: A continuous flow weighing apparatus including a support frame, a weighing drum rotatably mounted to an axle and having a plurality of weighing compartments each having an eccentric center of gravity. A balance beam is rotatably mounted on each side of the weighing drum to the support frame. One end of the balance beam is fixedly mounted to the drum axle while the other end is adapted to receive a counterweight. A releasable stop means is provided comprising a drum stop mounted to the exterior side of each weighing compartment. A fixed latch bar and a pivotal latch bar are attached to the support frame and are so configured as to form a notch for receiving the drum stops. The drum stops and the sides of the fixed and pivotal latch bars have inclined mating surfaces which form an angle from the horizontal to give a horizontal resultant force. A horizontal resultant force reduces weighing errors by stabilizing the center of gravity.

Abstract: Photographic images may be produced on a backing such as paper and polyester sheets, from photographic negatives which encompass line rendering, design comps, copy, complex color separation or the like with water-based varnishes and pigments, the resulting images closely resembling, if not exactly, the same image in its commercially printed form. Thus all aspects of color proofs produced by this invention provide greatly improved predictability as to the appearance of the final printed job, with a further improvement of cost savings over conventional techniques of preparing color proofs. Also, said proofing method can be used to provide a "transfer" so that one may transfer the colored image or images to a more suitable or required backing.

Abstract: A process for removing impurities from molten metal by propelling a bullet toward and into the molten metal at a velocity sufficient for the bullet to penetrate, vaporize, and react with the impurities. The bullet contains a reactive substance, is heavier than the molten metal, and is formed of a metal or metals which are to remain with the molten metal when it is solidified.

Abstract: A process for the delignification of cellulosic materials, wherein a high-yield cellulose pulp and high-value by-product, such as reactive lignins of low molecular weight are produced, which comprises degassing lignocellulosic material, rapidly heating the lignocellulosic material in a liquor comprising water, an organic solvent and a buffer thereby maintaining a substantially neutral solvent extraction, such that said lignocellulosic material is cooked in the liquor as it is heated from a temperature of 150.degree. C. to a selected maximum temperature in the range of 200.degree. to 280.degree. C.; and rapidly cooling the mixture to a temperature less than 150.degree. C. The reaction is controlled to maximize reactive lignin solvation while suppressing cellulose degradation.

Abstract: Magnesium bullets are shot into molten Ferrous alloys in a ladle to react with oxygen and sulfur to form magnesium gas and slag. Boron and ferro-boron bullets are also employed with magnesium bullets. The resulting iron alloys have superior physical properties. The machine which discharges the bullets into the ladle includes a first solenoid actuated gate supporting the lowermost bullet in a column of additive bullets received in a tubular upright magazine of an air gun so as to release the bullets by gravity, one at a time, into the chamber of the air gun.The air gun is disposed over a container of molten metal. A second solenoid actuated gate releasably supports the bullet in the chamber and a solenoid actuated valve in a compressed air line releases the air to drive the bullet down through the barrel of the gun and into molten metal. The angle of the counce can be varied. The arrangement is particularly useful for introducing magnesium into white iron and introducing boron into gray steel.

Abstract: A variable transmission output coupler and deviationless tuner forms a part of a tunable laser cavity. The device uses frustrated total internal reflection to provide variable output coupling and laser tunability simultaneously. Two Pellin-Broca prisms are pressed against each other by a variable spring pressure mechanism. An adjustable screw regulates the variable force, controlling the thickness of an air film between two prism faces. The Pellin-Broca prisms enable tuning the laser without angular deviation of the output beam. All beams enter and exit at Brewster's Angle, minimizing losses. No coatings are used on the optical elements, reducing the possibility of damage at high operating power of the laser. The coupler may be used in pulsed as well as continuous wave lasers.
