Patent number: 11802699Abstract: The Desktop Air Purifier with Double-layer Glass Tube Ultraviolet Disinfection Lamp (The desktop air purifier with DLGTUVDL) uses a turbo blower with an air filter to draw in outside air to be disinfected through its specially designed double-layer glass tube ultraviolet disinfection lamp. The ultraviolet disinfection lamp of the desktop air purifier has a double-layer glass tube with an inner glass tube and an outer glass tube. The center of the inner glass tube is a hollow space for external air to pass through and receive UV disinfection. This unique design allows ultraviolet rays to surround the entire hollow tube space to provide 360-degree ultraviolet radiation and disinfection at a close distance without dead ends, which greatly improves the disinfection efficiency. In addition, the desktop air purifier with DLGTUVDL has the function of natural plant scent air purifying agent to provide the disinfected air that carries the natural plant scents.Type: GrantFiled: March 16, 2021Date of Patent: October 31, 2023Inventors: Yan Zhang, Tianlan Zhang

Patent number: 11800886Abstract: Polyesters, such as those formed using polyols and di- or tri-carboxylic acids or anhydrides or salts thereof, are used as foam control agents in foodstuff processing. The polyesters are biodegradable and biocompatible while still providing excellent foam control capacity. In addition, polyesters foam control agents of the disclosure can be used with various apparatus while avoiding forming films that otherwise affect apparatus function. The polyesters can be used at various stages during industrial processing of vegetables (e.g., potatoes and beets) and fruits.Type: GrantFiled: November 19, 2019Date of Patent: October 31, 2023Assignees: Dow Global Technologies LLC, Rohm and Haas CompanyInventors: Wei Gao, Tianlan Zhang, Xue Chen

Patent number: 8764328Abstract: The PB Reader solves the problem that the e-reader presents: the e-reader has a non-paper screen and printed documents need assembly, binding, and page turning via hands. This is an electronic, mechanical device that can quickly search, review and print documents and that has text-to-speech and remote control functionality. The unit is rectangular in shape similar as a traditional book, including a viewing window for reading and printing. The unit is fed by two paper-belt rollers, across which images and printed text are displayed. The two paper-belt rolls, which are held by two square axles that are driven by the stepping motor through multiple reduction gears. A pattern of round dots is printed on the bottom side of the paper belt, which can be decoded by a photoelectric sensor to take action of reeling pages. The signals control the stepper motor, allowing the reader to reel the page forward or backward, or jump directly to a specific position.Type: GrantFiled: April 14, 2011Date of Patent: July 1, 2014Inventors: Yan Zhang, Tianlan Zhang
