Publication number: 20190309459Abstract: A pressure adjustment mechanism of the sewing machine presser foot comprises a motor, a screw actuated by the motor, a spiral spring and a pressing plate for pressing against an upper end of the presser foot. A nut is screwed and connected on the screw, and the nut is lifted or lowered by the screw. The pressing plate is underneath the nut. The circumferential direction of the nut is unfixed. The spiral spring is located between the nut and the pressing plate, an upper end of the spiral spring is pressed against the nut, and a lower end of the spiral spring is pressed against the pressing plate. The spiral spring is being compressed under the effects of the nut and the pressing plate.Type: ApplicationFiled: June 5, 2018Publication date: October 10, 2019Applicant: ZHEJIANG HONREY SEWING MACHINERY CO., LTD.Inventor: Xi Zheng

Patent number: 10378736Abstract: An LED bracket, LED bracket array, LED device and LED display screen are disclosed. The LED bracket includes a PCB circuit substrate and an insulating material. The PCB circuit substrate includes at least two electrically insulated electrode regions. Each electrode region includes a top electrode region, a side electrode region and a bottom electrode region. The side electrode region connects the top electrode region and the bottom electrode region into an integrated structure. The side electrode region is a side surface sunk from outside to an inner part of the PCB circuit substrate. The insulating material is filled in the side electrode region. An upper end surface and a lower end surface of the insulating material do not exceed an upper surface and a lower surface of the PCB circuit substrate. A thickness of the insulating material is less than a thickness of the PCB circuit substrate.Type: GrantFiled: October 31, 2017Date of Patent: August 13, 2019Assignee: Foshan NationStar Optoelectronics Co., Ltd.Inventors: Chuanbiao Liu, Feng Gu, Yuanbin Lin, Xiangling Luo, Xiaofeng Liu, Xi Zheng, Yan Liu

Publication number: 20190110629Abstract: A device and method for steaming and presenting of food deploys a spacer that rests on top of a cookware vessel. The spacer has a lower inner flange to support a steaming rack. A leg supported serving or presentation rack is adapted for lifting, supporting and presenting the steamed food when the spacer and steaming rack are lowered over it. The spacer has a larger inner diameter than an outer diameter of the presentation rack so that the spacer may be lowered around the presentation rack to engage the steaming rack along the presentation rack. The presentation rack has a sufficient height relative to the spacer height to dispose the food proximal to or above the rim of the spacer.Type: ApplicationFiled: December 11, 2018Publication date: April 18, 2019Applicant: Meyer Intellectual Properties LimitedInventors: Jacquelyn Maitram Truong, Xi Zheng

Patent number: 9401317Abstract: An assembly for a heat sink having a contact plate with opposing first and second faces, a plurality of fins extending from the first face of the contact plate, and a plurality of gaps between the fins. A retaining device has a first pair of opposing sides and a second pair of opposing sides, the first and second pairs of opposing sides surrounding an opening, the first pair of opposing sides having primary framing members, at least some of the primary framing members having a first end at a respective side and a distal free end, with at least one engagement member positioned proximate the distal free ends. The primary framing members define a receiving space for the heat sink. A metal spring is configured in a closed shape cross-section for engagement with the retaining device. The metal spring has a pair of elongated sides, a pair of truncated sides and heat sink engagement regions.Type: GrantFiled: January 26, 2011Date of Patent: July 26, 2016Assignee: Aavid Thermalloy, LLCInventors: Rui Sheng Tan, Xiong Zhang, Zhe Hong Liu, San Xi Zheng
