"The dispute between Mr. Hauge and his former employer, ERI, began more than thirteen years ago over ownership of intellectual property rights related to “pressure exchangers,” a type of energy recovery device used in reverse osmosis. On March 16, 2001, the parties entered into the Agreement resolving the litigation. Three days later, the district court adopted the Agreement and issued the 2001 Order, stating that ERI was to be the sole owner of three U.S. patents and one pending U.S. patent application: U.S. Patent Nos. 4,887,942, 5,338,158, and 5,988,993, and U.S. Patent Application No. 09/508,694, which later issued as U.S. Patent No. 6,659,731.1 "The Agreement and subsequent Order obligated Mr. Hauge to transfer ownership not only of the patents, but also “all other intellectual property and other rights relating to pressure exchanger technology” pre-dating the Agreement and 2001 Order. J.A. 10, 16. The Agreement states: “[t]his assignment and transfer of rights is not intended to extend to inventions by Hauge ․ made after the date of this Agreement.” J.A. 16. The Agreement also contains a non-compete clause, prohibiting Mr. Hauge from making or selling energy recovery devices for use in reverse osmosis salt water desalination for two years from the date of the Agreement. J.A. 18."

Dear Mr.Christopher, I am sorry if this message will bother you but I want to ask you an question regarding the PX device. I am a student from Algeria & I will do my project these on it! I want to know if the rotor inside turns out of the water pressure (as I am thinking) or there is something different that occur the rotary motion of it? again forgive me in advance in case you find this strange from me or if it will bother you. Respectfully, Nassir

"Using just the energy of the reject..." 0:52 "The rotor is turned by the flow itself..." 2:27 I'm no expert but based on the previous statements and the geometry of the fittings I'm pretty sure no additional work is needed. Good luck on your thesis!

thank you so much , you did make it so sure for me what i was assuming, now left for me to make it happen & make my study for it thank you so much here is my Email : [email protected] if anything you want from me specially with design or 3d real view rendering then just contact me Friendly, Nassir

+joao guilherme Me...as a beginner with CAD programs (total beginner, i need to choice from inventor or solidworks) i am very confused, because i' ve searched i while today and opinions like this seems discordants, some people says solidworks is more intuitive and easy, other that is more easy inventor, this is the best...no this is the best...how do i choose??

+kaoselite Solidworks is the most user friendly 3d cad.

Modelero thanks for the reply, autocad is more for architecture right?

+kaoselite plain autocad it's obsolete, yes, there is autocad mechanical but inventor is way better (and it's still an autodesk product)

kaoselite starting with inventor you will learn much more easy how to use a 3d cad software for mechanical engineer, after you learn the logic you adapt to solidworks if you need to use it, cause like Modelero said solid is the most user...

ايه الي كذب بظبط

I think that one you start using Solidworks you'll understand what the fanbase is talking about. You'll know that with solidworks it's never the program that is the limiting factor, but your skill with it.
