Abstract: ABSTRACT OF THE DISCLOSURE   A refractory siphon tube is inserted through the axial discharge opening of a rotary melting furnace and down through the slag into the metal within the furnace. Molten metal is withdrawn continuously by suction through the tube into an enclosed chamber maintained under a controlled negative suction pressure through a suction manifold connecting with a receiver, vacuum pump and pressure controller. The enclosed chamber discharges by gravity through a bottom opening, either emptying into a launder with an overflow weir, or discharging directly out through a bottom nozzle equipped with a slide gate shut-off.  The metal is discharged continuously at a controlled rate irrespective of any variations in the feed rate and metal depth in the furnace. The metal depth can be varied by periodically varying the suction pressure and thus can provide for intermittent slag discharge by overflowing the annular discharge open-ing. The depth of the enclosed chamber may be varied as desired, a high vacuum pressure being logically employed with the deeper units which thus also act as vacuum degassers for removing dissolved gases in the molten metal.

Abstract: ABSTRACT OF THE DISCLOSURE           A process of producing a uniform fiber dispersion involves the use of an in-line dispersing chamber to provide an average fiber dwell time of only about ten minutes and less. The chamber is provided with a plurality of weedless, nonthrust-ing impellers that generate regions of reduced pressure and flow disruptive turbulence of high intensity, the turbulence being of sufficient intensity to rapidly open fiber bundles and disperse the individual long fibers during said dwell time within said chamber.  The process produces a machine-made light weight glass fiber web material of exceptionally uniform fiber distribution. The web is comprised of micron diameter glass fibers having a fiber length of about 1/4 inch or more and a basis weight of about 5-30 grams/square meter.  The web material exhibits an isolated multi-fiber defect count of less than 10 per 100 square feet and a visually perceptible overall uniform fiber distribu-tion essentially devoid of "cloud effect" fiber density varia-tions.

Abstract: PROCESSED VEGETABLE SEED FIBER       FOR FOOD PRODUCTS                                ABSTRACT            A processed vegetable seed fiber, particularly soybean fiber, for use in food products.  Processing is accomplished by heating an aqueous slurry of the crude vegetable seed fiber to about 160°F., and then addingacid to reduce the pH of the heated slurry to about 3.5.  The elevated temperature of the slurry is maintained for up to about one hour while the slurry is agitated.   The resulting acid-pasteurized slurry is then dewatered to ob-tain a fiber material at about 20-30% dry solids.  Fresh water is then added to the dewatered fiber material to reslurry it to about 3-4% dry solids.  The reslurried fiber material is agitated at a temperature up to about 140°F. for about fifteen to thirty minutes, dewatered a second time, and then dried to about 10% moisture.  When crude soybean fiber is heated and treated with acid as described above, using sulfuric acid, the hilums of the seed hulls included as part of the soybean fiber be-comes distinctly lighter in color.

Abstract: IMAGE STABILIZATION SYSTEM FOR            CONTINUOUS FILM SCANNING APPARATUS         ABSTRACT OF THE DISCLOSURE                 An optical scanner system such as a projector for the continuous transmission of images to provide image immobilization is provided.  The optical scanner system includes an illumination system, a scanner mechanism, and a projection lens system.  The scanner mechanism is capable of creating virtual images of successive film frames with at least one virtual image point of each film frame positioned on a stationary locus point and at least another virtual image point offset from the stationary image locus point and relatively movable during a scanning movement.  The scanner mechanism can, for example, be of a reflective or refractive polygon geometry.  The specific para-meters of the projection lens system and illumination system recognizes the inherent limitations of the dynamic keystoning aberration in scanner assemblies and seeks to nullify its effect in the projected real image.  The projection means is of a tele-centric design.  The illumination system is matched to the vig-netting capabilities of the scanner and projection system to selectively illuminate different regions of a real image of each film frame so that the light transmission is progressively decreased in the region of each film frame when the relative movement of the real offset image point becomes progressively greater.  Basically, the system deluminates during the greatest rate of defocusing of the real image.

Abstract: ABSTRACT OF THE DISCLOSURE         A dc-to-dc converter having nonpulsating input and output current uses two inductances, one in series with the input source, the other in series with the output load.  An electrical energy transferring device with storage, namely storage capacitance, is used with suitable switching means between the inductances to obtain DC level conversion.  For isolation between the source and load, the capacitance may be divided into two capacitors coupled by a transformer, and for reducing ripple, the inductances may be coupled.  With proper design of the coupling between the inductances, the current ripple can be reduced to zero at either the input or the out-put, or the reduction achievable in that way may be divided between the input and output.

Abstract: ABSTRACT A three-phase alternating current pole-number changing rotating electric machine is disclosed.  The machine is of the type in which the stator winding, lying in a predetermined number of slots, is adapted for switching to provide alternative pole numbers by pole-amplitude modulation and is configured to have similar half-phase windings for connection alter-natively in series and in parallel.  It has been found that the presence of adjacent harmonics of m.m.f. waveform causes low frequency vibration of the machine frame, particularly in large motors of high pole-numbers.  The invention overcomes this problem by the specific design of the stator winding. Specifically, the slot number is divisible into two factors, the first factor being one of the numbers "6", "12", "18" and "24" and the second factor being the number "S" of slots of each half of an initial winding element of the said stator winding, the phase coil-distribution of the said initial winding elements in "S" slots having for a winding element itself a low adjacent harmonic content and near balance between phases.  The stator winding comprises a plurality of final winding elements wherein the number of final winding elements is derived from the number of initial winding elements by at least one stage of symmetrisation.  The invention is particularly beneficial in machines using asymmetrical pole combinations.

Abstract: ABSTRACT OF THE DISCLOSURE   An oven controlled oscillator assembly is described which has an evacuated enclosure, and a piezoelectric crystal plate within that enclosure. Mounting means are provided for thermally insulating the crystal plate.  The enclosure has at least one lid which includes an infrared transmitting window, and an infrared source in close proximity outside of the enclosure to emit radiation through the window to the crystal plate.  A reflector is mounted as a dome over that window, with the infrared source being positioned between the window and the reflector.  The emitted radiation is of a wavelength absorbable by the crystal plate.  Also provided are  temperature sensing means on the crystal plate, and temperature control circuitry for controlling radiation emitted from the infrared source so as to maintain the crystal plate at a predetermined temperature.  The oscillator assembly further includes oscillator circuitry and means for thermally insulating the crystal plate and oscillator circuitry from the environment outside of the assembly.  This configuration provides an oscillator assembly that has both a very small thermal time constant for fast warmup  of the crystal plate, and a very large thermal time constant giving insensitivity to external environmental changes. In one embodiment the enclosure is an oven enclosure provided with a piezo-electric crystal resonator therein.  In another embodiment the enclosure is a crystal enclosure with a crystal resonator provided therein.  In another preferred embodiment electrically conductive thin film strips form electrode tabs to the crystal plate. The tabs are oriented to minimize thermal transient effects caused by anisotropic heating due to the difference in absorbance between electrodes on which the tabs are formed and the crystal.
