Title: A method of inhibiting scale in a geological formation
Inventor: GHORBANI NASSER
IPC: C09K8/528
Filed: 2013-06-06
Granted: 2022-08-23
Abstract: The present invention relates to a method of inhibiting scale in a geological formation such as a hydrocarbon reser-voir and a kit of parts for perfonning the method. An organosilane is deposited on a surface of the geological fomiation.

Granted: 2017-03-21
Abstract: A multi-element lens of controlling defocus and eye diopter and an application thereof belong to the technical field of prevention and treatment glasses for myopia and hyperopia of eyes. One large unit convex lens (1) capable of generating large defocus is comprised. One small unit concave lens (2) capable of generating small defocus or focus through combination is combined on the lens of the large unit convex lens (1), or one small single lens (3) is separately provided on the large unit convex lens. When a human eye watches different distances through the lens, the central view region is in a small nearsightedness defocus or focus state, or a small farsightedness defocus or focus state, whereas the equatorial view region is always in a nearsightedness defocus state or farsightedness defocus state. Through the special influences of light on the view regions of human eyes, the growth of the ocular axis can be effectively controlled, which achieves the characteristics of good and fast prevention and treatment of myopia and hyperopia, and the use is convenient.

Abstract: Disclosed is a system and method for treating municipal and sanitary wastewater that uses only mechanical devices and processes, which eliminates biological processes and settling tanks. The system includes a three-output axial-flow type separator that separates wastewater into three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant sludge is mechanically dewatered without intermediary biological-process systems or sedimentation. The partially clarified water component can be directly filtered by a membrane filter and optionally optically or chemically disinfected for reuse or disposal. The system advantageously simplifies municipal and sanitary wastewater treatment eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.
