Publication number: 20150017856Abstract: An article includes a substrate and an intumescent coating to form an intumescent product in response to heating the article. The intumescent coating is disposed on the substrate and includes a primary intumescent precursor and a layered material that includes a silicate mineral, a layered double hydroxide, or a combination thereof. The primary intumescent precursor includes a carbohydrate polymer. A process for forming an article includes forming a liquid composition by disposing in a solvent a primary intumescent precursor and a layered material, contacting a substrate with the liquid composition, and forming an intumescent coating on the substrate to form the article.Type: ApplicationFiled: September 26, 2014Publication date: January 15, 2015Inventors: RICK DOWELL DAVIS, YU-CHIN LI

Patent number: 7918590Abstract: A composite lens plate is applied in a light emitting diode (LED) lighting device having a plurality of LEDs. The composite lens plate includes a plurality of refractive elements. The refractive elements are one-to-one corresponding to the LEDs and guide light emitted by the corresponding LEDs. Each refractive element has a refractive property. The refractive elements are classified into at least two types of lenses according to the refractive property. Lenses of the same type have substantially the same refractive property, and the refractive property of lenses of one type is different from the refractive property of lenses of another type.Type: GrantFiled: September 14, 2009Date of Patent: April 5, 2011Assignee: Leotek Electronics CorporationInventors: Yu-Chin Li, Po-Liang Huang

Publication number: 20080139576Abstract: Compounds of the formula provide pharmacological agents which are inhibitors of PTPases, in particular, the compounds of formula I inhibit PTP-1B and TC PTP, and thus may be employed for the treatment of conditions associated with PTPase activity. The compounds of the present invention may also be employed for inhibition of other enzymes with a phosphotyrosine binding region such as the SH2 domain. Accordingly, the compounds of formula I may be employed for prevention or treatment of insulin resistance associated with obesity, glucose intolerance, diabetes mellitus, hypertension and ischemic diseases of the large and small blood vessels.Type: ApplicationFiled: September 24, 2007Publication date: June 12, 2008Inventors: Gary Mark Coppola, John William Davies, Charles Francis Jewell, Yu-Chin Li, James Richard Wareing, Donald Mark Sperbeck, Travis Matthew Stams, Sidney Wolf Topiol, Isidoros Vlattas
