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:
The invention relates to mechanical engineering and can be used for friction assemblies. The aim of the invention is to develop a method for forming an antifriction coating for contacting sliding surfaces, which increases the constancy, resistance and life time of said antifriction coating when subjected to normal and intensive mechanical and temperature actions and to ensure a high wearability of the surfaces. The inventive method consists in placing a mechanically pre-activated pulverized mixture of a material and a binding agent, which form the antifriction coating, between the sliding surfaces. Compositions of natural minerals containing in mass %: Mg3Si2O5 (OH)4 - 10-60, MgFe2O4 - 10-60, MoS2 - 1-20, and of associated rare-earth elements - 0,1 - 10, H2O - not more than 5, are used as the material forming the antifriction coating. The mechanical pre-activation can be carried out with a pressure pulsation in a range of 0.01 - 10 MPa at a temperature of 100-200 DEG C.

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:
The present invention provides a transition metal/polymer matrix composite material which has durable, wear and corrosion resistant and friction reducing characteristics which can be used in a powder or liquid form, or, which can be bonded to a desired surface at ambient temperature. The specific components are transition metal dichalcogenide (TMDs) disulfides of tungsten and molybdenum, and the polymer polytetrafuoroethylene (PTFE). This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) and creates a synergistic interaction optimizing the friction reducing properties of PTFE with similar friction reducing properties of select TMD's, and, the TMD's additional wear-resistance and natural tendency for forming a tenacious physical bond at a molecular level. The invention comprises a mixture of PTFE and TMDs (particularly tungsten disulfide and molybdenum disulfide) which can be applied to a substrate through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 micron to 60 microns thick.
