Abstract: Crop foods such as peanuts, soybeans, peas, and the like, are ground and processed in a rapid, continuous, in-line production system. The food material is converted into a thermally processed slurry rapidly by mixing the ground food with hot water and steam and then quickly cooling the slurry, preferably in a vacuum chamber. The heat treatment stops the activity of enzymes which normally produce undesirable flavors and odors in mixtures of water and ground peanuts and other foods. The rapid cooling treatment prevents damage to protein content and simultaneously strips away any raw peanut flavor that may have developed. The continuous process produces a slurry of peanuts, or the like, without the characteristic raw peanut flavor, and the bland slurry can be further processed by drying to produce a useful food product such as flour, food extender, or the like.

Abstract: A device is provided for binding together sheets of paper formed with two or more spaced holes and attaching the same to a folder or the like. The binder preferably is injection molded of a semi-flexible material and is formed with a flat backing plate and at least a pair of stems which initially are parallel to one another and perpendicular to the backing plate. The stems are spaced apart by a distance equal to the spacing between the holes in the paper and are formed with co-operating male and female elements along the length thereof which allow the stems to be folded one against the other in locking engagement. Each stem is provided with a hinged stop at the free end thereof, which stop folds in against the stem while papers are being inserted or removed and swings out perpendicular to the length of the stem to prevent accidental separation of papers from the stem. Extension pieces are connectable to the ends of the stems and are provided with stop means at the ends thereof.

Abstract: A scanning X-ray source with an evacuated cylindrical chamber which bounds a cavity that is configured to receive a patient undergoing diagnosis. A moving electron beam is generated from a cathode which is attached to a rotating drum that is mounted within the chamber. The moving electron beam is directed towards and moves along a fixed annular anode mounted within the chamber. The points of beam impingement on the anode define a moving source of X-rays which sequentially irradiate the body from all directions. A plurality of detectors mounted adjacent the anode measure the amount of X-ray absorption. A processor receives the detected signals and reconstructs the absorption at each point to provide a two-dimensional density presentation for each body cross section.

Abstract: Alloys, of iron, cobalt, nickel and chromium containing both metalloids and refractory metals are disclosed. The alloys are rapidly solidified at cooling rates of 10.sup.5 -10.sup.7 .degree. C./sec so as to produce an ultrafine grained metastable crystal structure having enhanced compositional homogeneity. The as-quenched metastable alloys are brittle, permitting pulverization, if desired. Heat treatment is used to convert the metastable brittle alloys into ductile alloys with primary grains of ultrafine grain size which contain an ultrafine dispersion of boride as well as carbide and/or silicide particles. The powders or ribbons can be consolidated into bulk parts. The heat treated alloys possess good mechanical properties, in particular high strength and hardness, as well as good corrosion resistance for selected compositions, making them suitable for many engineering applications.

Abstract: A method and associated apparatus are disclosed for the continuous formation of single crystal silicon ribbons. A seed crystal is placed on the surface of a pool of molten silicon and pulled at a slight angle above the horizontal over the edge of a meniscus attachment member at a rate commensurate with the rate of growth of the ribbon. The formation of the ribbon is controlled in part by a submerged stabilizer disposed under the molten silicon below the advancing edge of the ribbon at the surface of the silicon. A thermal impedance is provided below the surface of the molten silicon to provide stability in the formation of the ribbon and to provide the proper temperature gradients conducive to the efficient formation of the ribbon from the molten material.

Abstract: A smoke detector which responds to the presence of smoke or other aerosol particles within a smoke chamber. The detector includes a photocell and a pair of light sources, one light source aimed directly at the cell and the other light source shielded from direct illumination of the cell, but aimed at an inspection zone to which the cell is visible. The first light source shines in a generally steady state directly against the cell to bias the cell to a predetermined level. Cyclically, the first light source will be turned off and the second light source will be turned on to illuminate any smoke that may be present in the inspection zone. If smoke is present in excess of that which corresponds to the pre-bias of the cell, the output will rise due to reflection of light from the second light source against the smoke and onto the cell. The output will remain the same if the amount of smoke is equal to the pre-bias and the output will drop if the smoke is less than the pre-bias.

Abstract: A method is disclosed for quickly and easily determining the presence and concentration of aflatoxins in peanuts. Aflatoxins are extracted from ground peanuts with a methanol-water solution using a tissuemizer. The extracted sample is filtered and an aliquot of the filtrate is transferred to a separatory funnel. A salt solution is added to remove interferences. The combined aqueous solution is then extracted with dichloromethane. The dichloromethane extract is evaporated to dryness, trifluoroacetic acid is then added and the resulting residue taken up in the mobile phase. The solution is then passed through a minicolumn for filtration and final cleanup. An aliquot is then injected into a high pressure liquid chromatograph system for separation of the four aflatoxin components, B1, B2, G1 and G2. Quantitation is done using a filter fluorescence detector.
