摘要:
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.
摘要:
This invention relates to a cleaning and lubricating solution for guns, gun bores, cartridges, and gun parts, and more especially for black powder guns, gun bores, cartridges, and gun parts. The solution is used to clean dirt and debris from the bores and other parts of black powder firearms and accessories. The solution cleans the bore and the residual material forms a protective coating or film of a light lubricating oil.
摘要:
Concentrated lubricant compositions, dilutable for use in high temperature metal forming processes and containing a triaryl phosphate ester; a non-ionic and/or amphoteric surfactant, an organic sulfur-containing extreme pressure additive, an amine salt of an organic acid, and, optionally, sodium thiosulfate, exhibit improved performance in forming operations and produce parts with less part to part variation.
摘要:
Disclosed is a lubricant carrier salt for facilitating the cold forming of a workpiece of iron or steel, based on boric acid and/or alkali borate. The salt has an additional content of aliphatic di- or tricarboxylic acid, which either is unsubstituted or substituted by at least one hydroxyl group, and/or of alkali salts thereof, the weight ratio of boric acid/alkali borate to the acid is (5 to 15):1. Especially appropriate carboxylic acids are malonic acid, maleic acid, succinic acid, tartaric acid and/or citric acid.Inorganic or organic thickening agents, such as bentonite and/or polysaccharide, aluminate and/or silicate, dispersants, lubricants and/or antioxidants as well as titanium salt can be contained as additional components in the lubricant carrier salt of the invention.Also disclosed is a method for facilitating the cold working of a workpiece of iron or steel, in which the lubricant carrier salt is applied to the workpiece, provided if desired with a phosphate coating, out of an aqueous solution or dispersion with a concentration of 5 to 30 wt-% and with a temperature of 80 to 100.degree. C. by the immersion or pass-through method.
摘要:
A permanent mold casting powdery mold releasing agent according to this invention consists of a granulated or powdery mixture of a lubricant, an organic polymer and a metal soap; wherein the lubricant is coated with the organic polymer or the metal soap. Therefore, the mold releasing agent allows productions of castings of high quality, in a parmanent mold casting work, with good workability and without worsening environmental situations.
摘要:
A die-casting powdery mold releasing agent according to this invention is a mold releasing agent comprising a mixture of powdery or granulated mold releasing base material composed of an inorganic compound as used for lubricant in a solid form and an organic compound giving adhesive property to the mold releasing agent, the both having powdery or granulated configurations, or configurations in which the organic compound is covered on the mold releasing base material. The mold releasing agent allows production of castings of high quality, in the die-casting method with good workability and without worsening environmental situations.
摘要:
A metal-working lubricant comprises an aqueous emulsion of (a) a long-chain aliphatic ester, amide, alcohol or acid, and (b) as a fugitive emulsifier an ammonium or volatile amine salt of a long-chain aliphatic acid. On application to sheet, e.g. of aluminum metal with a chromate or anodic oxide protective surface layer, the water and ammonia or volatile amine evaporate to leave a storage-stable hydrophobic lubricant. The sheet can be formed or made into adhesively bonded structures of shaped components.
摘要:
An oil lubricant for cold plastic processing of metallic material obtained by compounding either one or both types of polymers of 2-ethyl polyacrylate-hexyl ester and polymethacrylic acid lauryl ester with one or two types of oiliness improvers selected from the group consisting of refined lard, oleic acid, phosphate, hindered ester, isostearic acid, and C.sub.18 saturated higher alcohol and which are liquid at room temperature and which are compatible with the polymers. The oiliness improver is compounded as a thinning oil at a specified composition ratio.
摘要:
A lubricant composition comprised of (A) fatty acid, (B) polytetrafluoroethylene fluorocarbon resin powder (C) pyrogenic amorphous silica powder and (D) carrier. The lubricant is prescribed for use with a pneumatic tire and wheel assembly containing a run-flat device. The lubricant is contemplated as a component in such an assembly.
摘要:
A lubricant for working aluminium comprises an olefin or olefins of formula wherein R and R1 are hydrogen or fluorine, R1 may additionally be mono-, di- or trifluoromethyl and R11 is a saturated straight chain alkyl or fluoroalkyl radical having at least 8 carbon atoms. Preferred are straight-chain olefins or fluoro-olefins having 12 to 25 carbon atoms and unsaturation in the 1 or 2 position, and include cetene; 3,3,4-trifluorohexadecene-1; 1,1,1,2-tetrafluorohexadecene-2 and mixtures of olefins derived from the cracking of paraffin or the Fischer-Tropsch process. The olefins may be used by themselves, or with lubricating mineral oils or diesters, or diluted or dissolved in benzene, chlorinated hydrocarbons or kerosene. They may be also used in the form of aqueous emulsions or as greases. The effectiveness of the lubricants is compared with that of saturated compounds, or with compounds wherein the unsaturation is not in the 1- or 2-position.
