摘要:
A lubricant composition capable of effectively preventing a rolling surface of a bearing from flaking owing to hydrogen embrittlement. The bearing is lubricated with the lubricant composition. The lubricant composition is lubricating oil or grease. The lubricant composition contains a molybdate. The lubricant composition also contains an organic acid salt. At least one molybdate is selected from sodium molybdate, potassium molybdate, and lithium molybdate. The organic acid salt is a sodium salt of an organic acid having one to 20 carbon atoms. 0.01 to 5 wt % of the molybdate is added to the entirety of the lubricant composition. 5 wt % to 70 wt % of the organic acid salt is added to the addition amount of the molybdate. The lubricant composition forms a film containing a molybdenum compound in addition to an iron oxide film on a worn surface of the bearing.
摘要:
The exudate of macroalage is collected and selectively dried to produce a health supplement capable of oral, topical, or transdermal delivery to benefit the health of user. The macroalage is preferably brown macroalage of the species Macrocystis pyrifera and the exudate preferably collected within 12 to 24 hours of harvest. High purity Fucoidan derived from Macrocystis pyrifera is administered in an effective amount to benefit the health of a user. Collected exudate, dried exudate or High Purity Fucoidan may be combined with other materials such as krill oil to create a synergistic boost to Antioxidant power and health benefits.

One embodiment may include a gear assembly comprising at least one pair of meshing gears situated inside a gear case having a sump portion and a wall portion. A gear oil mixture may be disposed at least in the sump portion. At least one gear is immersed partially or fully in the oil mixture. The oil mixture comprises a hydrocarbon oil base and a coolant having an endothermic liquid/vapor transition at a temperature between the lower and upper operating temperatures of the gear assembly.
摘要:
A lubricant composition for a resin conveyor, comprising specific (A) a nonionic surfactant and (B) water and, if necessary, (C) (a) a cationic surfactant and/or (b) an amphoteric surfactant, and a method for using same. Using a specific nonionic surfactant as the main component provides excellent washing ability, lubricating ability, and stability in storage. In particular, because excellent ability to prevent stress cracking is attained, the lubricant composition for a resin conveyor can be advantageously employed for transporting PET containers. Furthermore, adding a specific cationic surfactant makes it possible to obtain a lubricant composition for a resin conveyor also demonstrating an effect of inhibiting microorganism (fungi) generation, without degrading the various original performances (effects). Furthermore, a preferred method for using those lubricant compositions for resin conveyors is also provided.
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:
An operable transmission comprising toothed wheels. In order to operate the transmission with a lubricant and coolant which is environmentally friendly while providing improved heat dissipation and temperature-independent viscosity, the transmission contains a mixture of water and a glycol or similar, in which graphite particles are suspended. The mixture contains 40 to 60 percent per weight of the glycol and 2 to 25 percent by weight of graphite in the form of flaky graphite particles having a grain size of less than 12 micrometers, the remainder being composed of water and other admixtures and/or additives. Also disclosed are the lubricant and coolant as well as a method for starting a transmission operated with the lubricant and coolant.
摘要:
Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.
摘要:
A well drill lubricant and shale stabilizer employs a sugar alcohol, such as glycerin or crude glycerol and graphite beads suspended in the liquid alcohol. A viscosity agent, such as a gum, is added to improve viscosity along with water. Some impurities present in crude glycerol, such as ash, methanol and MONG are present in small amounts. The composition is non-toxic, fully biodegradable, while possessing high coefficient of lubricity.
