Abstract: The present disclosure is directed to new ferritic alloys comprising iron, chromium, and silicon. The novel alloys have surprisingly enhanced corrosion resistant properties, with excellent workability, strength, and ductility. The disclosed alloys, and products made therefrom are useful in making low cost, efficient, and clean biomass stove combustors, as well as other devices for use with biomass fuel.

Abstract: A method and system for applying therapeutic stimulation to a patient stricken with paralysis or other condition. The inventive method includes the steps of: inserting an acupuncture needle against the spine of the patient and applying an electrical potential to the needle with a signal that mimics natural neural impulses in the body. The needle is located depending on the nature of the patient's condition. In the illustrative application, the needle is inserted against the ligamentum flavum of the patient's spine at L3. In the best mode, the patient's legs are moved during the application of the electrical potential. The inventive system is adapted to minimize a notch reaction and includes an electrode inserted into a tissue of the patient and a circuit for applying an electrical potential to the electrodes with a signal that mimics natural neural impulses in the body.

Abstract: A color negative photographic film wherein on the curve of density versus log E for each color sensitive record: (1) a straight line, which connects the point at density Dmin+0.1 and the point at 1.5log E above the exposure required for density Dmin+0.2, has a mathematical slope .ltoreq. 0.50; and (2) the difference in log E is .gtoreq.1.7 between the point 0.9log E above the exposure required for density Dmin+0.2 and the point where the density difference is 0.1 between the curve and the straight line which results from a linear regression of the three density points at exposures 0.3log E, 0.9log E, and 1.5log E above the exposure required for the density Dmin+0.2; and (3) the difference in log E is .gtoreq.1.20 between the exposure needed for density Dmin+0.1 and the point that corresponds to the exposure, in lux-seconds, of 9.2/(Film Speed). The exposure of the foregoing gray card is a typical normal exposure based on the film speed rating (i.e. the film is not overexposed or underexposed).

Abstract: Free-flowing plural extrudates of a polar ethylene interpolymer, and method of preparing the same. The extrudates are essentially coated with about 0.001-2 percent, by weight of the composition, fumed silica, preferably about 0.025-0.05 weight percent. The fumed silica has an average primary particle size of about 5-25 millimicrons, a surface area of about 200-250 m.sup.2 /g, and is substantially amorphous and non-porous. The interpolymer has interpolymerized therein polar monomer, such as acrylic acid, n-butyl acrylate, vinyl acetate, or the like, in an amount so that the untreated extrudates have high block. The extrudates are treated by admixture with the silica or by contact with an aqueous dispersion of about 0.01-10 wt. % silica. When the interpolymer contains .alpha.,.beta.-ethylenically unsaturated carboxylic acid, the extrudates are optionally surface neutralized with a base.

Abstract: The compatibility and thermal stability of blends of polyamides/carboxyl-containing ethylene polymers is improved by adding thereto an organic carboxylic acid compound, especially di-basic acids such as sebacic acid or tartaric acid. The blends may also contain free-radical scavengers and/or antioxidants. These blends are useful as heat-plasticized adhesives or bonding agents.
