摘要:
An auto-emulsifying cleaning composition capable of emulsifying upon contact with water, the composition in one typical embodiment comprising, based on the total weight of the composition, (a) from about 1% to about 99% by weight a blend of dibasic esters; (b) from about 1% to about 40% by weight of a blend of surfactants consisting of an organic anion neutralized with an organic cation, where either or both of the anion and the cation have surfactant properties, and the complex of which is soluble in the dibasic ester solvent blend. The blend of surfactants is typically a cationic surfactant and an anionic surfactant, which may or may not be used in conjunction with non-ionic surfactants. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl adipate, dialkyl methylglutarate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C1-C12 hydrocarbon group.
摘要:
The present invention relates to a method for producing a coating based on two organic semi-conducting compounds CP and CN, respectively of type P and of type N, CN being immiscible with compound CP in the coating produced, and wherein: (A) a solution is deposited on the surface of the support, comprising compounds CP and CN in a solvent medium S capable of solvating compounds CP and CN without chemically reacting therewith, said solvent S being formed by a mixture of: a first fraction formed by a solvent or a mixture of solvents S1 capable of solvating both compounds CP or CN; and a second fraction miscible with the first fraction consisting of a solvent or a mixture of solvents S2 with a higher boiling point than that of the solvent or mixture of solvents S1 and which is capable of solvating one of the compounds CP or CN but not the other one; and (B) the solvent S present in the thereby produced deposit is removed by evaporation.

An article includes (a) a glass substrate having a modified surface that comprises a glass surface and a layer of nanoscale inorganic oxide particles disposed in contact with and bound to at least a portion of the glass surface, and (b) a polymer layer disposed in contact with and bound to the modified glass surface. A method for improving the hydrolytic stability of an interface of a glass surface and a polymer surface, includes the step of, prior to forming the interface of the glass surface and the polymer surface, treating at least a portion of the glass surface with nanoscale inorganic oxide particles to modify the glass surface by depositing a quantity of such particles on the portion of the surface.

摘要:
The present invention relates to extended release pharmaceutical compositions of Levetiracetam and processes for preparing the same. The extended release tablet of Levetiracetam is with a core comprising of Levetiracetam and water dispersible rate controlling polymer, and the tablet core is optionally functional coated comprising a combination of water non-dispersible and/or water dispersible polymer. It provides extended therapeutically effective plasma levels over a twenty four hour period with diminished incidences of neuropsychiatric adverse events by eliminating the troughs and peaks of drug concentration in a patient's blood plasma. The composition also exhibits no food effect.

摘要:
For improving the accuracy of a speech recognition system, for the specific task of speech-to-text (dictation style speech) translation, a constrained dictation methodology using speak-and-spell mode is disclosed. The invention is perfectly suited for modern day “text-messaging” applications wherein the number of words being dictated is very small (limited by the 140-160 characters message length constraint). Additionally, the invention adds a control on the way users interact with machines, thereby making the speech recognition task easier and improving system accuracy.
摘要:
For improving the accuracy of a speech recognition system, for the specific task of character recognition, the character that is to be recognized or interpreted, is spoken in accordance with this invention, using simple coding-schemes that result in acoustic renderings that are well separated in the acoustic space. Furthermore, to relax the constraint on users for memorizing multiple words associated with multiple characters, in one embodiment, the coding-schemes are defined based on a combination of the given character and its neighboring/succeeding character(s).
