Patent number: 10196560Abstract: Described is a proppant composition comprising particulates coated with a polymeric coating comprising a polymerizable natural oil, and a method of making this composition. The polymerizable natural oil is a glyceryl ester that comprises greater than about 40% by weight of polyunsaturated fatty acids, or a derivative of this ester. The proppant composition is made by mixing particulates with a polymerizable natural oil and polymerizing the polymerizable natural oil to coat the surface of the particulates with polymer comprising polymerized natural oil. The composition may be used in a slurry that is used for hydraulic fracturing operations to improve proppant transportation and to mitigate proppant flowback.Type: GrantFiled: January 29, 2016Date of Patent: February 5, 2019Assignee: TRICAN WELL SERVICE LTD.Inventors: Kewei Zhang, Chuanzhong Wang, Weibing Lu, Leo Liu

Publication number: 20150289461Abstract: The present invention discloses a self-watering flower pot, comprising an outer pot, an inner pot and a water absorption rod connecting the outer pot with the inner pot. One end of the water absorption rod is inserted into the bottom of the said outer pot, and the other end protrudes into the soil of the inner pot. A support pillar integrated with the bottom surface of the inner pot makes the inner pot flush with the outer pot, with a well of water between the two. A water level indicator is placed in the flower pot so that users can check water level any time. The water absorption rod continuously waters the plant automatically. Convenient and time-saving, the device solves the problem of often watering.Type: ApplicationFiled: November 19, 2014Publication date: October 15, 2015Inventors: Leo LIU, Monkdy MENG

Publication number: 20110137278Abstract: A soaker pad for a cloth diaper comprising an outer layer, absorbent pad, inner layer, and side panels. The inner longitudinal edge of each side panel is folded inward to create a fold line and fold area. Elastics are located just inside the fold line to create an inner gusset. Elastics are situated parallel to the longitudinal edge of the outer layer to create an outer gusset. Neither the inner nor outer gusset is in contact with the inner layer. Each side panel is adhered to the outer layer in the margin along each longitudinal edge of the outer layer that is not in contact with the inner layer and along the outer margins of the inner layer. The fold area is adhered to the inner layer except at the middle portion of the fold area, thereby allowing the inner gusset to stand up and away from the inner layer.Type: ApplicationFiled: December 7, 2009Publication date: June 9, 2011Applicant: The Natural Baby Company, LLCInventors: Kim Ormsby, Allen Leo (Liu Ming)
