Patent number: 10234958Abstract: A first touch input can indicate a selection of a character from a first virtual keyboard configured for an Indic script. A modified first virtual keyboard can be displayed in response to the first touch input when the selected character is a consonant, the modified first virtual keyboard including diacritic forms of vowels from the first virtual keyboard. A second virtual keyboard can be displayed in response to the first touch input when the selected character is a vowel and a duration of the first touch input is greater than or equal to a predetermined duration, the second virtual keyboard including at least one of (i) diacritic forms of the selected character and (ii) vowels having similar sounds as the selected character. A second touch input can indicate a selection of (i) a vowel from the modified first virtual keyboard or (ii) a vowel from the second virtual keyboard.Type: GrantFiled: December 21, 2016Date of Patent: March 19, 2019Assignee: Google LLCInventors: Ruiyi Chen, Fan Yang, Manish Bhargava

Patent number: 9724619Abstract: The claimed invention provides a technique wherein the two column system is combined into a single column. The light components are concentrated on the prefractionation side (feed side) of the column, where they are removed as an overhead top product. The middle boiling components are removed as an overhead product on the opposite side of dividing wall. For the same product specifications, top divided column requires substantially lower capital and operating cost than a conventional two-column system.Type: GrantFiled: March 14, 2013Date of Patent: August 8, 2017Assignee: GTC Technology US LLCInventors: Manish Bhargava, Cole Nelson

Patent number: 8697917Abstract: Methods and systems for producing low methanol concentration acetone are provided. The method can include oxidizing and cleaving cumene to produce a crude acetone product. The crude acetone product can be neutralized in a neutralization unit to produce a neutralized crude acetone product. The neutralized crude acetone product can be fractionated in an acetone fractionation column to produce an acetone product and an acetone bottoms product. Methanol can be removed from the acetone bottoms product to produce a methanol-depleted product. The methanol-depleted product can be introduced to the neutralization unit, a dephenolation unit, or both.Type: GrantFiled: September 18, 2012Date of Patent: April 15, 2014Assignee: Kellogg Brown & Root LLCInventors: Theodor R.
