  • Publication number: 20240132747
    Abstract: A coated substrate comprising a coating extending over at least a part of the substrate. The coating is obtainable from a coating composition comprising (a) a polymeric binder; and (b) a feathering reducing agent comprising a carboxylic acid reactive functional group. The coated portion of the substrate comprises a pretreatment layer. The pretreatment layer is obtainable from a pretreatment composition that comprises a trivalent chromium compound. The invention extends to a method of coating a pre-treated substrate and a coated package, such as a metal can.

  • Patent number: 5636658
    Abstract: A high flow one-way or reed valve mechanism for use in the air/fuel supply system of an internal combustion engine. The reed valve comprising of a reed cage, reed cage ports, and reeds. The reed cage containing two converging main walls and two end walls. Each main wall is afforded multiple width wise reed cage ports. Each reed cage port is covered with a flexible reed. The high flow reed valve is designed to deliver large air/fuel flows into the cylinder of an engine while eliminating detrimental back flow and pressure fluctuations into the air/fuel supply source.
