  • Publication number: 20200010943
    Abstract: Disclosed are a method and a device for controlling flow of liquid zinc (2) in a zinc pot (1) for hot-dip galvanization. Under the blowing effects of an air knife above the zinc pot (1) for hot-dip galvanization onto strip steel (3), the liquid zinc (2) diffuses and flows outwards to zones (zones I, II, III and IV) comprising the left side, the right side, the front end of the zinc pot, respectively, and a zone between the strip steel (3) and a furnace snout (4), and surface dross rapidly generated on the surface of the liquid zinc (2) is driven to flow outwards to the zones (zones I, II, III and IV). On edge sides of the zones (zones I, II, III and IV), travelling magnetic field generators (71, 72, 73, 74, 75, 76, 77, 78, 712, 756) are arranged in multiple sections above the surface of the liquid zinc (2) in the zinc pot (1), so as to excite a travelling magnetic field to generate an electromagnetic driving force on the liquid zinc (2) to drive the flow of the liquid zinc (2).

  • Patent number: 10530104
    Abstract: The present disclosures relates to cable-connector assembly with heat-shrink sleeve. The coaxial cable-connector assembly comprises: (a) a coaxial cable having an inner conductor, a dielectric layer circumferentially surrounding the inner conductor, an outer conductor circumferentially surrounding the dielectric layer, and a polymeric jacket circumferentially surrounding the outer conductor; (b) a coaxial connector having a central contact attached to the inner conductor of the coaxial cable, an outer conductor body attached to the outer conductor of the coaxial cable, and a dielectric spacer interposed between the central contact and the outer conductor body; and (c) a heat shrink sleeve that conformably overlies a portion of the cable jacket and a portion of the outer body of the connector.

  • Patent number: 10273325
    Abstract: Dispersions of polyurea particles are made by reacting polyisocyanate compounds and coreactants that include at least one polyamine while dispersed in a base polyether. The polyisocyanate or the polyamine, or both, has a functionality of at least 2. A highly preferred coreactant is an alkylthio-substituted aromatic diamine such as 3,5-di(methylthio)-2,4-toluene diamine. The dispersions have extremely small particles, which promotes storage stability.
