  • Patent number: 10527406
    Abstract: Disclosed is a method and device for determining the loss on ignition of at least part of an iron and steel product during passage through a furnace upstream of a descaler. The device includes electromagnetic sensors, with at least one arranged to scan the product's lower surface near the furnace outlet, the sensor oriented so the scanning plane of the electromagnetic radiation from the sensor is perpendicular to a direction of movement; a set of at least two electromagnetic sensors upstream of the descaler, oriented so their scanning planes are substantially on a single plane perpendicular to the direction of movement of the at least part of the product; and at least two electromagnetic sensors downstream of the descaler, oriented so their scanning planes are substantially on a single plane perpendicular to the product's movement direction. The sensors determine the height of the product upstream and downstream of the descaler.

  • Publication number: 20120135250
    Abstract: An antimicrobial article prepared by a method includes forming an antimicrobial mixture by adding a calculated amount of antimicrobial agent to a solution of water and alcohol, depositing the antimicrobial mixture in a container, the antimicrobial mixture having a thickness of 0.1 ?m to 10 ?m, evaporating the water and alcohol of the antimicrobial mixture to form the layer of antimicrobial coating, adding silicone resin on top of the layer of antimicrobial coating and allow the silicone resin to permeate and crosslink with the layer of antimicrobial coating, and removing the silicone composite with the layer of antimicrobial coating from the container.
