  • Patent number: 10640660
    Abstract: The invention relates to a coating for preventing intermetallic bonding, in particular to a water-based high-temperature-resistant titanium-steel anti-bonding coating and its use in the preparation process of titanium ingot. The water-based high-temperature-resistant titanium-steel anti-bonding coating of the invention includes the following components in parts by weight: 50-150 parts of water-based film-forming agent, 0-50 parts of Zn powder, 400-450 parts of Al2O3 powder, and 250-350 parts of talcum powder. The coating of the invention can avoid the bonding reaction with a roller or a winch of the steel equipment in the rolling or perforation process of a titanium tube at 900° C., so as to improve the yield and the production efficiency of titanium material processing. Moreover, the process is simple and easy to operate, the coating is environment-friendly and pollution-free, and easy to prepare.

  • Patent number: 10640889
    Abstract: A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating the film industry with the textile industry.

  • Publication number: 20200137741
    Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to be in agreement on spatial quasi co-location (QCL) assumptions for transmission in certain scenarios. The techniques may be used, for example, to determine QCL assumptions for downlink transmissions sent in an initial control resource set (CORESET) on an initial downlink bandwidth part (BWP) where dedicated signaling of such assumptions may be lacking. In some cases, the techniques may involve a UE determining a beam to use for monitoring for a physical downlink control channel (PDCCH) transmission on the initial CORESET in the initial downlink BWP that lacks dedicated signaling of QCL information and monitoring for the PDCCH on the initial CORESET in the initial BWP using the determined beam. Other aspects and features are also claimed and described.
