  • Publication number: 20050061998
    Abstract: A UV sterilization system with autocleaning structure comprises scrubbing collars, at least one cleaning liquid box and at least one sliding bar. Said cleaning means further comprises at least one towing bar, at least one sliding bar and at least one supporting bar. The boxes are vertically mounted on or fixed to the supporting bar(s) to form together with the supporting bar(s) a rectangular shape. A cleaning liquid addition port and a cleaning liquid drain port are respectively provided at the top and close to the bottom of each cleaning liquid box. Said cleaning liquid addition port is connected with a cleaning liquid supply pipe and the cleaning liquid drain port is closed by a detachable sealing member. Several sets of holes with the same diameter for scrubbing collars are provided on the opposite sides of each box with each set at the same height. Each UV lamp is separately installed within a protective sleeve passing through the scrubbing collars.

  • Patent number: 6022626
    Abstract: The performance of natural rubber based products, such as engine mounts which are susceptible to degradation caused by heat, oxidation, ozone attack or ultraviolet radiation is significantly improved by coating exposed surfaces of the product with a polymeric material having excellent heat and oxidation resistance properties. By applying such polymeric coatings having high resistance towards oxidation under excessive heat, the C.dbd.C bonds of the natural rubber are protected from oxygen and ozone attacks, thereby allowing its strain-crystallization characteristic properties to be retained.
