Publication number: 20030065066Abstract: A novel class of UV absorbers, ortho-hydroxyphenyl substituted triazine compounds bonded to aminoplast resins is provided. Compared to unanchored stabilizers, the anchored stabilizers disclosed herein have increased compatibility with coating resins and have reduced volatility due to higher molecular weights resulting from anchoring. A process for preparing the anchored stabilizers by the reaction of triazines containing active hydrogen with alkoxymethylated aminoplasts in the presence of a catalytic amount of acid. The novel ortho-hydroxylphenyl substituted triazine compounds are bound to the aminoplast resins by carbon-oxygen, carbon-carbamoyl nitrogen or carbon-active methylene carbon linkages. The aminoplasts include alkoxymethylated derivatives of glycolurils, melamines, and urea-formaldehyde resins.Type: ApplicationFiled: July 23, 2002Publication date: April 3, 2003Inventors: Dennis John Jakiela, Ram Baboo Gupta, Thomas P. Sassi, Gottfried Haacke

Patent number: 6365652Abstract: This invention relates generally to amido or carbamate substituted trisaryl-1,3,5-triazines and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of trisaryl-1,3,5-triazines comprises an aryl ring attached to the triazine ring (and preferably an aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine ring) substituted with a group comprising a bondable amido/carbamate containing group para- to the point of attachment to the triazine ring. These materials may, under the appropriate circumstances, be bonded to formulations comprising coatings, polymers, resins, organic compounds and the like via reaction of the bondable functionality with the materials of the formulation.Type: GrantFiled: May 3, 2001Date of Patent: April 2, 2002Assignee: Ciba Specialty Chemicals CorporationInventors: Ram Baboo Gupta, Dennis John Jakiela, Thomas P.

Patent number: 3987781Abstract: Cadmium stannate has been found to be useful as a window for solar heat absorbing systems in which advantage is taken of the unique optical properties of cadmium stannate. When cadmium stannate is in an electrically conductive state, having a conductivity of greater than 10.sup.3 ohm.sup..sup.-1 cm.sup..sup.-1, it becomes transparent to solar radiation and reflective of thermal infrared radiation. This enables the cadmium stannate to function as a window which allows passage of solar radiation through it and incident onto a black body, and at the same time serve as a reflector of thermal infrared radiation emitted from said body. This results in more efficient solar heat transfer to the solar heat collector provided with such a window.Type: GrantFiled: May 27, 1975Date of Patent: October 26, 1976Assignee: American Cyanamid CompanyInventors: Arthur Jack Nozik, Gottfried Haacke

Patent number: 3968639Abstract: Accumulating measuring devices which indicate the flow of electric current on graduated scale. Current flow may be of any fixed rate or value, steady or pulse, and scale may be any desired graduations. Current flow is indicated by a persistent electrochromic display material which changes color due to passage of electric current through it. The entire device is electronic, with no mechanical parts. Other accumulating functions may also be measured with the device if they can be converted first to electric current. One particular application is an elapsed time indicator, e.g. a watch or clock.Type: GrantFiled: July 16, 1974Date of Patent: July 13, 1976Assignee: American Cyanamid CompanyInventors: Donald Joseph Berets, George Augustus Castellion, Gottfried Haacke
