Patent CA-2897369-A1 (CA)
Inventor: WERKER ALAN GIDEON
IPC: C02F3/12
Filed: 2014-01-10
Abstract: A method of biologically treating wastewater and, at the same time, incorporating processes that aim to increase the PHA accumulation potential of biomass used in the treatment of the wastewater. The method includes biologically treating the wastewater and enhancing PHA accumulation potential of the biomass by subjecting the biomass to a primary feast-famine process where the biomass is subjected to repeated cycles of feast and primary famine conditions. From time-to-time, the method entails deviating from the primary feast- famine process to a secondary famine process. The secondary famine process comprises subjecting the biomass to secondary famine conditions for a period of time that is substantially greater than the average time period of the primary famine conditions.

Abstract: A hydrostatic variator having a common yoke design and two or more bent axis piston drive units is disclosed in which the rotating group of a drive unit is arranged to be movable relative to the yoke to alter the angle between its drive shaft axis and rotating group axis independent of the other drive unit. This can be accomplished using movable sector plates coupled to the rotating groups that are arcuately movable within the yoke about the axis perpendicular to the respective drive shaft axes of the drive units. Such variators enjoy the response and packaging advantages of a common yoke design while still allowing dynamic adjustment of system size. In turn, varying system size allows for efficiency to be improved at conditions other than at the maximum design torque.

Abstract: Web pages of a website are parsed and a set of n-grams are generated from the parsed web pages. A relevancy value is determined for each n-gram and a second set of n-grams is generated by removing any n-gram in the first set whose relevancy value is below a threshold. A third set of n-grams is generated at least by removing those of the second set of n-grams that have been determined to be similar to another one of the second set of n-grams. Responsive to determining that there is not a web page that is directed at an n-gram, a web page is automatically created with content directed at that n-gram including reusing existing content of the website that is related to the n-gram. One or more links to the created page are added to web pages so that the created page is not an orphan page.
