Abstract:
A lubricating composition and method are disclosed for lubricating the inner wall of a hollow conduit and the outer surface of an insulated flexible electrical conductor installed in the conduit. The lubricating composition is a powder comprised of the following powdered ingredients: lubricant such as talc; drying agent such as a micron-mesh silica; surfactant such as calcium stearate; odorant such as sassafras; and colorant such as a nontoxic food or cosmetic dye. The lubricating method first includes the step of blowing a quantity of a powdered lubricating composition into a hollow conduit resulting in the deposition of powdered lubricant on the inner wall of the conduit. In the next step of the method, an insulated flexible electrical conductor is inserted into the pre-lubricated conduit whereby powdered lubricant on the inner wall of the conduit rubs off onto the outer surface of the insulation of the electrical conductor thereby lubricating the insulation as it advances through the conduit.
Abstract:
The present invention relates to a lubricant for use in the drawing and ironing of black plate steel during the manufacture of enclosed containers such as cans. The lubricant comprises an aqueous solution of an active component, such as a major portion of molybdenum disulfide, together with minor amounts of waxes and other materials. In performing the method of the present invention, a lubricant system is employed. The lubricant system comprises a dual lubricant coating. The first, or outside, coating is applied to that portion of the black plate steel which ultimately becomes the outside surface of the can body. The outside coating is applied, such as by spraying or gravure or offset printing, at a rate of about 25 to about 200 milligrams per square foot of steel surface. This coating is dried, as through the use of a heat source, such as infrared heat or hot air. A second, or inside, coating is applied to that portion of the black plate steel which ultimately becomes the inside surface of the can body. The inside coating may also be applied to the surface of the black plate steel in a manner similar to that used for the application of the outside coating. After the can body is produced, the outside and inside lubricants must be totally removed. Such removal may be achieved by washing the can bodies in an alkaline solution (pH about 7.5 to 11.5) having a temperature of about 140.degree. to about 160.degree. F.

Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly, or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
Abstract:
An anti-seizure agent for hot steel working that exhibits excellent wettability and surface film-adherability comprises: an inorganic component (first component); sodium hydroxide (second component); water-soluble resins and/or water-soluble surfactants (third component); and water. With the mass of the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2.0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al2O3, SiO2, CaO, B2O3, K2O, and Na2O. A coating layer formed after application solidly adheres to the steel and does not come off in the environment of both cold and hot working.

Abstract:
The present invention relates to a method for screening and identifying test compounds that bind to a preselected target ribonucleic acid (nullRNAnull). Direct, non-competitive binding assays are advantageously used to screen libraries of compounds for those that selectively bind to a preselected target RNA. Binding of target RNA molecules to a particular test compound is detected using any physical method that measures the altered physical property of the target RNA bound to a test compound. The structure of the test compound attached to the labeled RNA is also determined. The methods used will depend, in part, on the nature of the library screened. The methods of the present invention provide a simple, sensitive assay for high-throughput screening of libraries of compounds to identify pharmaceutical leads.
