United States Patent Law
Under United States law, a patent is a right granted to the inventor of a (1) process, machine, article of manufacture, or composition of matter, (2) that is new, useful, and non-obvious. A patent is the right to exclude others, for a limited time (usually, 20 years) from profiting from a patented technology without the consent of the patent holder. Specifically, it is the right to exclude others from: making, using, selling, offering for sale, importing, inducing others to infringe, applying for an FDA approval, and/or offering a product specially adapted for practice of the patent. History 1623. England adopts Statute of Monopolies, which has been acknowledged as a legal predecessor of the US patent law. 1789. U.S. Constitution in Article I, Section 8, Clause 8 authorizes Congress "to promote the Progress of . . . useful Arts, by securing for limited Times to . . .

Synthetic Lubricants
Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in Stamping (metalworking)#Synthetic stamping lubricant, metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks. There are various types of synthetic oils. Advantages of using synthetic motor oils include better low-and high-temperature viscosity performance, better (higher) Viscosity Index, viscosity index (VI), and Chemical stability, chemical and Shear stress, shear stability, while disadvantages are that synthetics are substantially more expensive (per volume) than mineral oils and have potential decomposition problems. Description Synthetic oil lubricant comprises chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemists' Club
The Chemists' Club is a private club in New York whose membership is open to research and industrial chemists from all areas. The Chemists' Club filed for incorporation on December 9, 1898. The Club's goal was "to promote the interests of chemists and those interested in the science and applications of chemistry", by providing academics and industrial chemists with space to meet, work, and study. It provided a place for members of various chemical societies to meet and mingle, including the American Chemical Society, the Society of Chemical Industry, the , the American Electrochemical Society and the American Institute of Chemical Engineers (AIChE). From 1910 to the 1980s, the Club was located at 52 East 41st Street, New York City. Built by the architects York and Sawyer, the 41st Street building contained areas for talks, meetings, and dinners, living and laboratory spaces that could be rented by members, and a world-class chemical research library.

Dibasic Ester
Dibasic ester or DBE is an ester of a dicarboxylic acid. Depending on the application, the alcohol may be methanol or higher molecular weight monoalcohols. Mixtures of different methyl dibasic esters are commercially produced from short-chain acids such as adipic acid, glutaric acid, and succinic acid. They are non-flammable, readily biodegradable, non-corrosive, and have a mild, fruity odour. Dibasic esters of phthalates, adipates, and azelates with C8 - C10 alcohols have found commercial use as lubricants, spin finishes, and additives. Applications Dibasic esters are used in paints, coil coatings, paint strippers, coatings, plasticisers, resins, binders, solvents, polyols, soil stabilization, chemical grouting, oilfield drilling fluids, crop protection products, cedar spray, and adhesives. References See also *Dibasic (other) Dibasic may refer to: * Dibasic, or diprotic acid, an acid containing two potential protons to donate * Dibasic salt, a salt with two h ...
