Patent number: 11124448Abstract: A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an addition product of an amine and a reactant to form an amino-amide intermediate. To the amino-amide is added an aldehyde or ketone to form the curable binder composition. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.Type: GrantFiled: May 9, 2018Date of Patent: September 21, 2021Assignee: Johns ManvilleInventors: Bernhard Eckert, Bernd Christensen, Kiarash Alavi, Souvik Nandi, Jawed Asrar, Mingfu Zhang

Patent number: 6670350Abstract: A method of administering dienogest to a women in high dosages for reducing the body of the breast is described. The dosage should be at least ten times the effective dosage for inhibiting ovulation in the women. A pharmaceutical composition for use in the method is also described. Furthermore, retrogression of mastopathic changes in the body of the breast can be brought about. Dienogest is also outstandingly suitable for the prophylaxis of mastopathies. In high dosages, dienogest prevents the formation of mastopathic changes in the body of the breast.Type: GrantFiled: January 14, 2002Date of Patent: December 30, 2003Assignee: JenaPharm GmbH & Co.

Patent number: 5085842Abstract: A process for scavenging hydrogen sulfide from gases, in which the hydrogen sulfide-containing gas is introduced into an aqueous glyoxal solution of at least 15% by weight strength at a pH of a solution of 5 to 11 until the molar ratio of glyoxal to hydrogen sulfide is 3 to 2. The solid reaction product obtained in this way, which contains the hydrogen sulfide in bound form, is separated off. Owing to its stability and insolubility in acids and bases, it can be disposed of without problems.Type: GrantFiled: January 23, 1991Date of Patent: February 4, 1992Assignee: Hoechst AktiengesellschaftInventors: Christoph Porz, Bernd Christensen, Elena Kyaw-Naing, Walter Gulden, Erich F.
